Storyline

Why Are Thin People Not Fat?The world is affected by an obesity epidemic, but why is it that not everyone is succumbing?

Medical science has been obsessed with this subject and is coming up with some unexpected answers. As it turns out, it is not all about exercise and diet.

At the center of this programme is a controversial overeating experiment that aims to identify exactly what it is about some people that makes it hard for them to bulk up.

    Ooh, very interesting! I wonder if Morgan Spurlock found it easy to get back to his original weight after Super Size Me...

  • Karen

    This video kept freezing up, didn't stream well.

  • http://www.1001recipe.com/ Ciph3ro

    This documentary makes a whole lot of sense.

    I found out that when you reach your natural weight you can tell just by the way you feel. For me it was around 90 kg. lol. Also pays off to keep in shape rather than find your natural weight.

    I still don't see someone's "natural weight" set point being 300 lbs though ... as many "modern humans" that I've seen are around that.

  • Yavanna

    Your "natural" weight is variable accordingly to age related metabolism. I was a skinny fricker till about 35 - used to be able to eat anything drink anything - pig out generally. Then I ballooned. Even so I can still lose weight very easily - I lost 6 stone last year when I put a bit of effort into it. I have my beer belly back now however.

  • Yavanna

    Karen I often have problems with streaming.... When i do I put off viewing you tube until all the yankies are snuggly in bed.

    Lainy regarding Morgan spurlock i seem to remember it took him a whole year to recover form his McDonalds experiment. I have to ask btw are you Loraine Read?

  • doc watcher

    I was shocked to find out the luck out dude of Asian descent put on muscle instead of fat with the excess calories.

    seems to defy logic. would then he be able to eat his way into a body building competition without lifting?

  • Bill

    This documentary sounds particularly clueless with regard to why people gain weight. They need to read Gary Taubs "Good Calories, Bad Calories".

  • Charles B.

    Wow! Boy am I depressed now. So, do I have a "chicken virus" or am I just genetically predisposed to being overweight?

    I thought it sad that when fat people loose weight their brains make them feel like they are constantly starving until they gain the weight back.

    I was just born in the wrong time period I guess. My ancestors had long lives and made it through the depression and starvation (seriously) just fine, so my ars if fat now, and hopelessly so. Thanks, gramps!

    I'm fat but my wife is slim. She eat rice by the plates full; and chocolate. My son (age 3) is slim, and it's sooooo hard to get him to eat anything, but my daughter (17 months), even as we speek (litterally) has fork in hand and is on the kitchen table with bread and jam.

    We're raised both the same, but my boy is obviously genetically taking after my wife, but I sure hope my lovely little girl doesn't follow too much in my foot steps. She trying to feed me bread and jam now! LOL :-)

    P.S. The boy hates bread and jam and has eaten none today despite it's easy availability.

  • karen

    This is possibly the stupidest documentary I've ever seen. The very fact that they're being constricted from their normal amount of exercise creates a huge additional variable. The fact that they're suddenly eating not just more, but a completely different diet because they're responsible for figuring out on their own what to eat to boost their caloric intake is another enormous variable. Would an extra dozen eggs have the same effect as a belgian chocolate shake?

  • karen

    Continuing on, there's no uniformity of what they're eating or how much they're exercising. They're Also not considering how much the subjects were eating before hand. Perhaps for one person, their calorie target is three times their maintenance diet, where for someone else it's double, but that person used to run every day. How on earth can they isolate some 'obesity immunity' when there is no continuity in the actions of the(incredibly small) sample group, and no consideration of their starting points? Good grief, they're not even being photographed in the same clothes. What sort of scientific study photographs bodies in street clothes? Idiocy.

  • Dreighen

    You tell em Karen!

  • nil

    excess calories are excess calories, whether it's 500 calories worth of broccoli or 500 calories worth of potato chips.

  • Lauren

    Well Your body digests calories from chips differently then calories from apples. You don't see a diabetic refuesing to eat an apple because his/her sugar is high do you? no.
    So to everyone who is saying "excess calories are excess calories" that may be somewhat true,but not every calorie is concidered "equal" in the human body.
    oh and sorry for any spelling mistakes it is not my strong point lol

  • lala

    @Lainy- his wife, a vegan cheif, put him on a vegan diet to lose the weight

  • wq

    Wow Martin Wong must be a long lost cousin of mine or something because I'm also like him (except female and chinese-american). I used to be miserable growing up because I would eat a huge amount of calories in a desperate attempt to gain weight/feminine curves and never did. But I was always very athletic and physically strong so maybe the reason my weight gain could be measured by the scale but not visible to the eyes was because I had an increase in muscle mass. Now that I'm at the ripe old age of 26, I can no longer eat the way i did without gaining weight. the good news is, the weight that I've gained is just the amount I want because I FINALLY have boobs now!

    there definitely is a genetic component in resistance to weight gain because the vast majority of my family are slim to normal. None can be categorized as even remotely near obese.

  • http://pulse.yahoo.com/_YMEIYFWGIZSQS434OSWAGMIEPY Jake

    Interesting doc... I would have liked to be among the participant to test how much weight I could really put on for a month. However there's only few issues in my case... I have severe case of hypoglycemia... whatever i eat gets burn so fast that when I was young I could eat a bag of sugar and be ready for another one two hours later. I also have a disgust for everything super greasy... fast food disgust me; no pizza, no hamburgers, I hate potatoes so no french fries, hotdog (unless they are homemade) hasn't got desert for the last 15 years, and I'm super lactose intolerant.

    Well I guess I wouldn't have been selected LOL.

  • http://www.facebook.com/profile.php?id=1195441119 Max Jakovii Gandy

    I'm on part 5/7, and what I keep thinking of is "maybe the people who aren't gaining more fat were eating less grams of fat and/or sugar."
    I dunno. I'm no doctor, but they should have tried to control that aspect, also.

  • http://pulse.yahoo.com/_ZUYWMXDB3L3ULT5CKYBO3EE5OQ Jonathan

    How about measuring how many calories aren't absorbed by the body? There are calories in fecal matter so why is it that nobody has considered that maybe some bodies don't actually metabolize those calories?

  • http://www.facebook.com/KIRAsMiSAMiSA Misa Amane

    It's stupid... trying to fit all people in little categories. Every body is different. It doesn't matter what you look like as long as you're a happy, hard-working citizen. But even so, a person should never let themselves get TOO FAT or TOO THIN. We should all be fit ;)

  • http://www.facebook.com/KIRAsMiSAMiSA Misa Amane

    Why the hell would anyone want to gain weight? Everyone is literay dying to lose it. :S

  • http://www.facebook.com/KIRAsMiSAMiSA Misa Amane

    160 pounds is NOT skinny. Lose some weight.

  • Sieben Stern

    I think you have a good point. from my own experience i find that eating cheese / drinking milk, dairy products make me gain weight super fast, second is meat and third sugar. Maybe everybody metabolizes energy sources differently, so if they happen to love eating what they metabolize the best, then they can eat all they want and not get fat.

  • Gary V

    Another superb, interesting & informative doc from the BBC Horizon team.

  • fasffeaf geamna

    I didnt really like this movie mostly because I was a fat child myself and lost weight during my teens but now the weight is creeping back up on me.. I think it should point out the reasons for being fat or thin but it should also bring inspiration to fat people not hopelessness by suggesting ways to lose the weight and to tell us that were not bound by these childhood behaviors or genes

  • http://www.facebook.com/people/Matt-Siess/1295240290 Matt Siess

    why do you need inspiring? shouldn't that be an intrinsic motivation? and basically all that was said is that there is a predisposition to being fat or skinny. just like there predispositions to diabetes or cancer or allergies or moles or freckles or blonde hair or blue eyes or depression and so forth and so on. further more it did not say that it was impossible for a fat person to be skinny or vice-versa it just stated that it is more difficult for some people. so its no wonder we celebrate those who overcome their difficulties (i.e. the biggest loser) and if anything this should be inspiring because it said we are bound to your genes as you should want to disprove this point

  • stevenmilward.mail

    This is me all over, i can eat anythying... in actual fact, i might go and eat a massive cream donut now, and not feel guilty one bit... because my natural weight is already determined, i wont even have to worry about it!!! I think i might go and eat 7 actually. UNLUCKY FAT PEOPLE! Lets just hope i dont get the 'fat virus' lmao!

  • stevenmilward.mail

    Its a documentry on what makes thin people thin! If you dont like the hard facts then dont watch it.

  • http://twitter.com/geronajoy joy (? ? ?)

    an excellent documentary! theories were proven. and now i understand why eventhough my sister & i eat the same amount of food everyday, she NEVER gets fat but I do. hehe. but this doesn't mean that i would stop my diet & exercise. it makes me feel healthy. ^-^

  • http://www.clairemorawski.com Claire Morawski

    Also at the end they showed that the Asian guy (sorry don't remember the name) did gain weight - but it was more muscle than fat. Hence, his metabolism rate also increased. Wondering if he ate more lean protein than the rest?

  • http://www.clairemorawski.com Claire Morawski

    Not when you are trying to lose weight. As 500 calories of potato chips will increase your sugar levels in your body and will give you an insulin spike - making you hungry after a few minutes. Hence you would eat more than thsoe 500 calories. On the other hand 500 calories of broccoli (or preferably of lean meat) will keep you full till your next meal (for about 3 hours). The GI index helps with this.

    I used to be the same then I regulated my intake of sugar, unless its dark chocolate because if you eat sugar it must be consumed with a fat. Also eat high fibre meals Low Gi etc. It will help you register when you are full and for longer. Good luck and please don't resort to unhealthy measures!

    Do I know the feeling. The only way I would ever be at the healthy weight of 115 (that's the high end of healthy weight for my height) is being anorexic as well. :/ I did the whole regulating intake thing and nothing. I'm still a fat 125 pound-er. I can't get rid of that extra ten pounds. I did went to a doctor and he suggest that the fat I have can't be burned off through diet or exercise. The fat I have is the extra fat cells that I gathered as I was growing up. I was at 162 pound and dropped to 125 pound in a year, but the extra fat cells are still there, they just gotten smaller. I'm going to suck them out with smartlipo. I'm just not going to develop an illness over something that can be fixed with surgery, since everything else doesn't seem to work for me.

  • http://pulse.yahoo.com/_JNIWLD2N7KE6YWLCZBXZ5EC3RQ Yusiley S

    You're kidding right? For a man 160 is actually healthy, especially if it is muscle weight. >_> To you and your distorted concept of weight every guy in UFC is unhealthy and obese.

  • http://pulse.yahoo.com/_JNIWLD2N7KE6YWLCZBXZ5EC3RQ Yusiley S

    Men want to bulk up to gain muscles. >_> Men aren't women. Men who have a 28 inch waist and are above 5 ft tall look nasty and sick. For a man to look healthy with a 28 inch waist has to be 5 ft tall. I've seen guys who are 5ft 5 inches tall with a 24 inch waist and they look ugly. Sorry but men are suppose to be bulkier than women. I can't stand a bony guy.

    Also you stated in a earlier comment that everyone is different and yet here you are stating why would anyone want to gain weight. >_> Hypocrite!!!!

  • http://pulse.yahoo.com/_JNIWLD2N7KE6YWLCZBXZ5EC3RQ Yusiley S

    Yes but what is too fat or too thin? I have a cousin who would be categorized as anorexic yet he eats more than I do. O_O He eats very hearty and healthy yet he would be what many would call being "too thin." >_> We ought to do away with the whole idea of body shape and weight, and just focus on eating healthy for the individual. F**k this collective BS ideology of what is too fat and too thin. It clearly doesn't work.

  • http://pulse.yahoo.com/_JNIWLD2N7KE6YWLCZBXZ5EC3RQ Yusiley S

    I lost weight by just eating 1,200 calories and cycling for two hours a day. It worked for me. I'm still going under the knife to reshape my body to my ideal shape. I want to have a smaller waist than my hips. Unfortunately, my hips are narrow so there is no diet or exercise I could do to get the hourglass look I want. F*** everyone else I want to have the body of Dipannita Sharma. To me that's the perfect body shape I want for me.

  • colin1123

    Talk about being obsessed with your looks. I personally am disgusted by girls like you who spend all their time reflecting on their looks. Talk about a turn off.

  • Sieben Stern

    it might not just be blood type but that might coincide with type of metabolism - i think the issue is that there is no hard fast rule, no magic bullet that helps people stay healthy, because we're all internally different.

  • Sieben Stern

    it might be healthier for you to turn off the tv and put down the fashion mags ^^ and talk to a therapist about your body issues.

    I heard that too, but upon review I believe he says "P-I-T-A w/ Mayonnaise". Though concerning strange British tastes Turkish delight chocolate bar tastes like a decorative soap covered in chocolate. Hard to find Tikka Masala in the States though.

  • Largactyl

    Thank F*@# for the Brits/Canuckidans and their socialist medical care system, because of this we can get REAL info from peer reviewed legit clinicians and scientists unlike in the States where big pharma either owns out right or has a controling interest in every medical school and controls the purse strings of almost every University level researcher's grants. The US is in decline because ignorance has been a boon to those who can profit from it and most Americans are too busy w/ the latest cell phone apps and/or reality TV programing.

  • Mike Staffieri

    obesity is not a one factor thing...it's genetic and epigenetic...many fast foods...high salt/sugar/fat are addictive, spiking dopamine levels with opiate like after effects. They should measure Intestinal Alkaline Phospatase(fat busting enzyme) of the subjects and obese people. Take your probiotics and your "fat virus" will disappear

  • http://www.facebook.com/people/Gary-Ark/100001833760078 Gary Ark

    The problem with ALL obesity research is that it's goal is not to find a solution, but to find another blockbuster drug that would have to be taken on everyday basis. That guarantees a total failure just like the "war on cancer".

  • lifesucksass

    I allow for the idea that some people are genetically predisposed to weigh more or less, but the majority of people don't differ violently enough to escape the fact they will, with a healthy lifestyle sit within the 'healthy' bmi range...that's what averages mean.

    And even if you don't sit in that category (like myself), when did regular exercise and a healthy diet cause anyone more problems long term?

    An overweight person saying 'I cant lose weight - I'm genetically predisposed to being overweight' is like me saying the same about being underweight. Yet, I accept I can push into that 'healthy' bracket with a little more work. I CHOOSE not to exert the extra effort required to achieve that, so I don't whinge when (as happens almost daily) people comment on my being underweight.

    The difference between my being underweight and -for eg- my friend who is overweight isn't in which end of the spectrum we sit in terms of weight, but in attitude.

    The other day, I said she might benefit from directing her frustration about being overweight into going for a brisk walk, that it'd help her -in the long term- fight her negative feelings much as anything...and her reply was 'depression runs in my family, I cant escape it wherever I damn well walk'.

    I'm bipolar and have been underweight my whole life despite having always had a very healthy lifestyle; I know well as anyone exercise and diet isn't going to 'cure' bipolar or change my body type.

    The issue isn't genes or illness, it is attitude. my friend says a walk isn't likely to cure her weight problem or depression. I say walking isn't likely to make things worse, and may just alleviate my reactionary depression and improve my physical health...so lets do it.

    As for 'fast food is addictive'...if that information is true it has an instrumental and positive use in identifying and then addressing the problem of people who are addicted and in preventing addiction more generally. But it seems all the 'genetically predisposed to being overweight', 'under active thyroid' and 'fast food is addictive' theories often only serve as excuses by people who are unwilling to accept responsibility for their lives and their bodies.

    You are not fat because you have problems; you are fat because you won't address those problems...

    Amen.

  • roberto bertulfo

    Do fat people actually eat more than the thin people per hour, per day, per week and so on...? Record their habit of physical movement, and frequency of eating and total it for the whole month, fat people actually take in more food compare it to thin people. (Fat people think that he equation for food is 1X1X1....=X, but 1+1+1...=X). The more you put into your mouth, the more you gonna get it. Fat people crave for food more times than the thin people.
    Fat people when they see a lot of food they have a big appetite, while thin people when they see a lot of food, they are disgusted.

    I recently became vegan. Eat less. I make all my own food. I don't eat junk food at all. I exercise daily and I'm still struggling to loose a couple of pounds. My body always gets stuck at this weight. I have a positive attitude and I try daily. I'm always hungry and I don't eat the food and the weight isn't coming off. It's ridiculous. My husband is eating the same foods as I am, exercising and he is getting ripped. He's been skinny his entire life. I even exercise more than he does and I do it better. He can not keep up with me in the exercise. So yes, my body for some reason is reading this weight as normal.

    No, I have an IQ of 150 and thighs just as big.

  • http://pulse.yahoo.com/_QDKURLFMOQCLTWPOJ4ZILHQMEE she

    I do too. And I also think different kinds of genes are more prevalent in different populations. I truly believe the Asian population has a higher prevalence of people like Martin.

  • freegin

    What happened to their health statistics ? They didn't comment on that. Those who didn't gain weight, I suspect their cholesterol and blood pressure for example went up, so their risk of cardiovascular diseases increased.

  • http://www.facebook.com/JuditVictor Judit Victor

    I do think fat kids happen to parents who are obsessed with food, whether healthy food or not. The thing is not to make kids overly conscious of food, in my opinion. I remember taking my young toddler to a paediatrician coz he wouldn't eat and the goodly doc said: "so what's your problem?" he'll eat if his hungry (after ruling out anything else) - my son grew up as a thin person, like the rest of my family. We start cooking when we're hungry and then they'll sort of eat on the fly. I've noticed ppl going into intense discussions about food in front of their babes. I think don't do it.

  • http://www.facebook.com/JuditVictor Judit Victor

    Oh and we're now all on ketogenic diets, because we were born with heterozygous familial hypercholesterolaemia. That changed our lives lipid-wise. We eat fatty meat, cream, fatty fish, chicken with skin, duck, goose, almost zero carbs and we've just gone thinner, but with best lipid profiles ever in our lives. Doctors are astounded. Very easy life direction - we like our food now to boot.

  • Daniel Wilder

    I like that you want to keep it simple. The problem as I see it isn't that people have are too conscious about their food but rather that there is too much contradictory information, some of it simply lies, about what is healthy. The overwhelming amount of contradictory information can be very stressful and encourage a poor relationship to food, which I've experienced in the past. Eventually since I got over this by beginning to /carefully/ source my information to eliminate the corporate propaganda, I find my studies very beneficial in making good health decisions.

  • Daniel Wilder

    This documentary was very poorly done.
    The Asian man who put on muscle wasn't asked if he'd previously had that muscle. Anyone who knows anything about putting on muscle mass knows that there is adaption which goes on in your nervous system that makes re-adding muscle MUCH easier than adding new muscle. In one case, 40 pounds of muscle was re-added in 40 days with only a few hours of training per week, which would be impossible for adding NEW muscle mass. (See Tim Ferris for this case, btw.)
    Also the fact that source of calories was not examined is a major flaw in the experiment, which for this and other offenses deserves to be thrown out. The nutrient density of the 5,000-calorie diet was not even discussed, nor the thermogenic potential, since certain foods like sat-fats/sugars/starches naturally increase metabolism while others like soda/coffee/fruits decrease it.

    The whole documentary was unscientific and I suspect bore undisclosed conflicts of interest in its creation, just like those that are frequently seen in newer PBS documentaries (which I have more experience investigating).

  • Daniel Wilder

    Don't go crazy with exercise and never starve yourself to the point of being uncomfortable. Discard the 'calorie in=calorie out' theory and concentrate on eating healthy. You want to nourish your body, make your life comfortable, and let your body know that it's secure and that it's safe to come out of starvation mode because you've acquired a healthy diet and self-nurturing lifestyle for it.

    You may even be suffering from too few calories for too long, which has depressed your metabolism. Matt Stone does work on increasing metabolism; I also recommend thermogenic foods from my experience, like hot peppers.
    If you still have problems, it's probable that you have a latent long-term health condition which you should see a /specialist/ to have diagnosed and treated.

  • Daniel Wilder

    The problem with the 'calorie in-calorie out' reasoning is that it assumes people constantly make the decision of what to eat from an array of whatever is hypothetically available to them in a grocery store. But a vast majority of people have nowhere near this luxury.

    People are not adequately educated about nutrition because the companies that make them unhealthy selling processed foods publish enough biased research to keep the scientific community ever in-doubt. By keeping information about GMOs 'inconclusive' for instance, Monsanto hopes to push into the marketplace and gain enough staying power that the eventual conclusion of the scientific community will be irrelevant. This was the same strategy used by cigarette companies.
    More than education, institutions that provide food options often do not provide healthy ones, and nobody can buy healthy food from a cafeteria which offers none.
    And most importantly of all, the human body has powerful urges which when listened to, guide people to make good decisions about their health; the body can only make the lesser-of-evils decision when faced with no good prospects.

  • Daniel Wilder

    I have seen evidence which demonstrates that diet can in fact cure bipolar disorder for at least some people. If you would like to pursue such an option, please research Dr. Natasha Campbell-McBride's Gut and Psychology Syndrome (GAPS) program. Healing your second brain has profound benefits for your 'first brain'.

  • Daniel Wilder

    This guy gets it!

    This topic strikes close to home for me, so here's my advice taken from a ton of research and personal experience:

    Don't go CRAZY with exercise and never starve yourself to the point of being uncomfortable. Discard the 'calorie in=calorie out' theory and concentrate on eating healthy. You want to nourish your body, make your life comfortable, and let your body know that it's secure and that it's safe to come out of starvation mode because you've acquired a healthy diet and self-nurturing lifestyle for it.

    You may even be suffering from too few calories for too long, which has depressed your metabolism. Matt Stone does work on increasing metabolism; I also recommend thermogenic foods from my experience, like hot peppers.
    If you still have problems, it's probable that you have a latent long-term health condition which you should see a /specialist/ to have diagnosed and treated.

  • Daniel Wilder

    Sound advice, but I should like to add that 'fat addiction' is only a problem if it's trans fat or an excess of the less-healthy fats, since saturated fat is your body's preferred energy source. Salt and sugar as well are useful as energy sources if not consumed in excess quantities, like processed foods are liable to encourage.

  • Daniel Wilder

    So right. If you get this reply, please tell me if you know where I can find information on the production of this 'documentary'. I've found that several similar BBC and PBS documentaries bare astounding conflicts of interest, even being primarily funded by companies whose products are one-sidedly plugged in the documentary.

  • Daniel Wilder

    Please take care of yourself. A calorie restriction diet that severe will be very difficult to maintain long-term, so please don't be discouraged if you regain much of the weight you've lost.
    The most important thing you can do is to maintain a good diet and low-stress lifestyle with exercise, which will assist you in not suffering irresistible hunger pains that cause you to gain back the weight. You really should eat a lot more calories, especially at least once a week to keep your metabolism up. Otherwise your body will have a very problematic reaction and consider itself in starvation mode, for which it will try to store up as much energy as possible. (Tim Ferriss' 'slow-carb- diet has an interesting take on this.)

  • Nitea

    Bigger people have bigger stomachs - the bigger the stomach, the more calories you intake... And the more weight you put on. The more weight you put on, the bigger you get. The bigger you get, the more energy you need. The more energy you need, the more you need to eat. The more you need to eat, the bigger the stomach gets. The bigger the stomach, the more calories you intake...

  • Catedi

    What a bunch of BS! Bigger people do not have bigger stomachs. Nor, do they crave more food! I was a thin person all my life. 67" and never over 135#, until i gained 75# in 6 months. I really knew something was wrong and found out I had Hoshimoto's thyroiditis. The thyroid meds are are a weak replacement at best. I still can't loose weight and my BP and Cholesterol have increased considerably, despite I'm nearly vegan and ingest scant amounts of animal products, and never any butter, cheese, or milk-fat of any kind. As far as craving more food; I only get hungry around once a day. This is a classic symptom of Hoshimoto's-low appetite. I've always been a nibbler, and the current studies show, I've the classic pre-disorder profile: thin female with history of low appetite. Also, here's a kicker; 1-10 adults have this disorder in the USA. I know, because I'm an RN and have done the research. So, just saying, you people don't know what you're talking about and let your fear and prejudice of fat people control your thoughts.

    I do think there's a combination of factors, but I can say my mom is definitely obsessed with food. If I call her, it's "So what did you eat today?" If we go out, it's, "Where did you eat?" When my kids go to her house she obsesses about having enough junk food. When I was little, I was praised for how much I could eat, and sometimes I would eat so much and get really food, and my dad would force me to eat the last few bites. I wasn't an obese kid, so when I got old enough to make my own food decisions, I just ate what I wanted and figured people must have to be doing something really extreme to gain a lot of weight. I felt as though I was addicted to food and worried about the 10 or 15 lbs I could lose. I ended up with a huge appetite, and now, I don't ever feel full. After leaving the military at a relatively healthy weight, I stayed with my mother and ate the same _amount_of food; however, it was very fattening food. I gained 60 lbs in 6 months. My appetite changed. I've lost weight several times since then, but never to my original weight, and I've always gained it all back.

    I'll admit, I could do more, but it seems a serious struggle. I can eat my weight in non-buttered, plain broccoli. It's not about cakes or cravings for me. Although I do have a weak spot for pasta. My mom is overweight and she's different. She craves variety of foods, which is maybe a symptom of a food obsession.

    Yes! When one is overweight and tries to change, he is flooded with all sorts of information: Eat no carbs. Eat lots of fruits and vegetables. Count calories. Never count calories. Weigh yourself daily. Rarely weigh yourself. Eat a diet high in proteins and low in carbs to satisfy cravings. Become vegan. Eat 1200 calories a day. Eat enough calories to cover exercise. Drink green tea to reduce appetite. Drink water. Don't drink stuff with caffeine. Listen to your body. You may have a higher appetite than you should, so learn to accept hunger pains. Get 30 minutes of aerobic activity a day. Don't do aerobics, but build muscle mass to increase your metabolism. At the end of it, we struggle to do these things in ways that never fit naturally into our lives, lose weight, then slowly gain it all back then some. It's not that we lose our last pound then head for a bag of crisps. It's that we can't always just "listen to our bodies." Some people really do have overactive appetites and cravings. Some don't. Some people live where it's easy to naturally get more exercise. Some don't. The reality, I think, is that the conflicting messages are there because different people have different weight challenges. You may be genetically predisposed to obesity and have grown up with certain food habits that might not make your peers eventually gain weight, but for you, you did. You may not have an obesity gene at all but just grew up with a family obsessed with food. You might just hate healthy food and like your sodas and quick fixes. You might have underlying issues affecting your weight gain. It could be the way you eat.

    You have another ailment which can't be helped. But definitely same way as the skin stretches the stomach does to accommodate all the food so they DO end up with bigger stomachs. No-one I think here is prejudiced or fearful of fat people. I feel sorry for them because people stare and when they're young girls life is just really hard for them. Such is life. Drinkers and addicts can hide their vices but a person addicted to food unfortunately cannot hide it. But definitely NO judgement from me. I'm sorry for the whole lot - some of us have bad genes, so just no-one on G-d's earth is totally problem free within their bodies.

  • Judit

    I understand so fully what you are saying!! SO true although I think they meant well?

  • devrie

    Yes, I think they did mean well! :)

    You have a thyroid condition that definitely keeps on weight but the percentage of the population with a thyroid condition is very small. The majority of people who are obese or overweight are so because of lifestyle: what they eat, how often they eat and how much or little they exercise. I didn't find anything in the documentary to increase fear of fat people. Your notion that fat people are fat because of some condition is groundless and that ones stomach cannot stretch is medically groundless. We know for example that a morbidly obese person say weighing over 300 pounds can lose weight in a controlled environment. We also know that that same morbidly obese individual has a stretched stomach which can be altered through stomach stapelling.

    You are correct but insulin is manipulates by the contents of ones diet ie. a high starch, carbohydrate diet. At the end of the day all roads leads to the quality, content and amount in ones diet and the amount of calories burned.

  • Lucy Saw

    So how would you know? Considering everyone in your family is genetically thin? Studies show fat kids usually have heavy parents. Children with heavy parents will eat what the family eats which is commonly a high fat, high carb diet.

  • Judit

    Wasn't being facetious Lucy. But we just sort of ate whatever, We never spoke about food. Only something like: Oo look, there's a guava tree, let's get some and then it was finished. But NOW since we found out that we have a serious hereditary condition, I have to get my sons on a high fat diet (doctors don't get it) but the LCHF diet gets my cholesterol down to normal-ish numbers and that's nothing short of miraculous. I see this post is a year ago and my heart is so sore. My son had to undergo QUINTUPLE bypass surgery over this past Christmas. I was floored - the youngest ever in that heart hosp. to have gotten it. So now I am going through a very deep depression. But I've noticed he does Keto dieting and I'll softly support him coz I know it works. BUT I can't get over it. Veggie diets will kill us.

  • Hypocrites

    Because we don't constantly stuff our faces.

    You're not breaking the laws of physics, fatties: if you're gaining weight, it means you consumed it.

    Mass is NOT spontaneously generated within your body.

    My question to You is:

    Do you do ANY exercise at All,
    or do you sit around All day,
    on the computer, and snack on food.

    I'm overweight, myself, and I can tell you
    that I pretty much do NOTHING but sit here...
    and I've gained 40 lbs.

    Thyroid or not, please tell me what your physical
    activities are.

  • JoeBloh

    Big people can have 'little' stomachs too.

  • jesterx7769

    ...you had a thyroid disease. Totally different.

  • Jacky Montecinos

    As a thin person for all my life I can definitely identify myself with the study people. It is what it is, it really is in the genes!

  • jennyct

    The national weight registry had studied hundreds of people and the bottom line is they maintain their weight loss by continuing to stay on a low calorie plan FOR LIFE. They eat less than you... to stay at a normal weight. Perhaps if everyone who was prone to gain weight knew this, they wouldn't gain the weight back.

  • jennyct

    BMI is genetic, so people who tend to gain weight easier need to eat less than you... forever. We keep giving guesstimates on what the average person needs to fuel themselves, but it's just that. A guess.

  • jennyct

    Lucy, if you are correct, then adopted children will be whatever their adoptive parents are.... which has been proven wrong many times over.

  • jennyct

    Where are you getting this info? Please give your references.

  • jennyct

    Read the data gathered from the national weight registry- most women MAINTAIN their weight loss with 1300 kcal and exercise for the rest of their living days. We're doing a disservice to people if we claim they should be smaller on more calories.
