The Skinny on Obesity

Storyline

What are the main factors that contribute to the obesity epidemic, and how can we halt the tide of weight gain before it disastrously alters the average life span of the human species? Renowned pediatric endocrinologist Dr. Robert Lustig, the author of the viral lecture Sugar: The Bitter Truth, has spent most of his professional career in search of these answers, and the documentary The Skinny on Obesity provides an eye-opening overview of his considerable efforts in this field of study.

For Dr. Lustig and his colleagues, obesity is our modern plague. "The reason we're in this epidemic can be summed up in one statement," Dr. Lustig contends. "That statement is a calorie is a calorie." In his view, mass-scale weight gain transcends this overly simplistic equation. Instead, obesity is more deeply rooted in the cultural and environmental factors that have worked to redefine our existence in recent decades. Our industrialized diet is designed to provide fast and cheap food on the go, and consists of unfamiliar ingredients and chemicals manufactured in highly profitable food laboratories. These products thrive in the global marketplace because they serve a culture that prides convenience over healthy nourishment, and sedentary lifestyles over physical activity.

Beyond all other considerations, however, the one factor that proves most detrimental to our health is sugar. The presence of these sugars is particularly insidious in foods that advertise low calorie content, since they are often used to supplement a deficiency of taste. Therefore, the high volumes of sugar in the vast majority of processed foods unarguably prove that a calorie is definitely not just a calorie. "Sugar is 50 times more potent than total calories in explaining diabetes rates worldwide," Dr. Lustig explains. It is also the main culprit in the development of metabolic syndrome, and the resulting cases of Type 2 diabetes, heart and liver disease, hypertension, dementia, and cancer which accompany it.

The Skinny on Obesity offers a wholly convincing argument on the dangers of sugars, and sheds light on the means by which we can combat its prominent threat to our well-being. In the larger sense, the obesity epidemic has resulted from a destructive shift in our culture, and solutions may only be met by redefining our relationship to the foods we eat.

    I read through the comments before watching the video and was a bit surprised at the very different opposing views.
    Well I watched it and my opinion is that those with the reactionary opinions didn't really listen to it all.
    Sure, the comment that "no food in nature has the carbs and fat" is not literally true but as someone else pointed out the proportions of them in natural grown foods is not equal but heavily biased one way or the other and also mostly come with a healthy dose of fibre to slow down the uptake of the sugars so there isn't an insulin spike.
    This video is getting a bit old now that were in 2018 and by what I can make out it was made in 2010.
    There is now conclusive evidence that the hypothesis in this video is correct. Try and get a look at the Docu series "The Real Skinny on Fat" hosted by Naomi Whittel. It is a 9 episode series with some of the episodes going for over 2 hours. It is gripping and if the information contained in that series can get out to the general population I think it will change the world.
    I was 102 kg a few years ago and lost around 10 kg and was still about 9 - 10 kg overweight and I just couldn't get any more weight off. After watching the series I decided to lose some more weight. I started by cutting out all processed carbs(bread, pastry, pasta, etc and cut out all packaged foods which nearly all contain added sugar and trans fats. (Trans fats wasn't mentioned in this video) and I already didn't use sugar as a sweetener or regularly have sugary foods.
    If you have the typical diet mentioned in this video then you probably rightly are saying now that this is very hard to do.
    What I am about to say will shock most people and is totally opposed to what we all have been taught about diet and health. FAT IS GOOD.
    Yes that is right fat is good. Good fats such as olive oil, coconut oil, avocado oil, butter(yes butter) and a whole bunch of other oils. Since the 70's we have been told fat is bad and the food industry has jumped on the bandwagon and come up with lots of low fat and diet foods and at the same time the fast food industry has come up with a convenience menu full of sugar and bad fats. (Canola, Cottonseed, corn, Sunflower, Safflower, Soy being the most prolifically used)All of these oils already contain trans fats which are very toxic and when they are heated they produce alot more trans fats and that is what they are used for, cooking. These oils are unstable and go through a high degree of processing to make them into the clear/yellow oils we all know. Google how is canola oil made and see if you want to have any after finding out.
    Enough of the bad fats, the good fats are great. As I was saying before, I cut out alot of carbs and sugar and I started to lose weight. At the same time I also increased my good oil intake by applying a liberal amount of olive oil to salads and cooking liberally with butter.
    After 2 weeks I had lost 2kg. I hadn't even changed the amount I eat.
    I was intrigued. I didn't mention that I was quite skeptical when I started watching the series. I thought this is working whereas before I had to fight off urges to eat things I knew wouldn't be good for me and more often than not I found myself unable to sustain my will power to abstain.
    Now the crucial thing to understand is this. Fat is satiating, ie it gives you a feeling of satisfaction and takes away hunger. After losing the 2kg I thought I would try an experiment on myself based on one of the interviews in the series with Dr Valter Longo who is the author of "The Longevity Diet". He introduces the concept of the Fasting mimicking diet(available as Prolon through l-nutra.com).
    I thought that I didn't want to spend the money on the fasting mimicking diet food so I came up with my own formula also from the series.
    While watching the series I discovered the coffee bomb which is made with one shot of coffee, 1 tbsp butter, 1tbsp coconut oil and a bit of stevia if you can't handle coffee without the sweet taste. Add water to make up the volume and mix with a stick blender and there you have it. Looks just like a milk coffee and tastes good.
    This coffee bomb is so satisfying that you can go without food for a long time. Now besides feeling satisfied I got thinking that I need nourishment so I added bone broth to my diet made from organic chicken and vegies. 1 cup at each meal time. It is so nutritious and satisfying . apart from these two things I didn't eat anything for 8 days. (The fasting mimicking diet is 5 days) I only stopped because I lost the 7kg I wanted to lose in that time. Yes that is right 7 kg in 8 days. I'm not saying everyone will lose the same amount as everyone is different. The thing about it is that I could have kept on going because I truly just wasn't feeling hungry. I did feel a little slugish at times but the bone broth seemed to take care of that. Maybe if I do it again I will have some bone broth more often.
    Starting to eat again has to be done carefully. ie eat light small meals for a couple of days.
    I read the Longevity diet book and have decided to adopt it in principle with the option of permitting myself to indulge occasionally.
    Well, I have shared my opinion and I hope someone gets something from it. If you do then pass it on and help someone else.

    The obesity epidemic must be blamed on the FAST FOOD INDUSTRY and the HAND HELD GADGETS occupying people day and night. When you eat processed, refined, and manufactured food continuously day in and day out, your busy 24/7 with the electronic gadgets you hold in your hands and you do not move your body = you are and become a glutton and a sloth with an obese stomach and grobin tuchas! What's so difficult to understand?

    The documentary lost me once he said no food has both carbs and fat, and then lists avocados, olives, and coconut. All three contain carbs and fat. They are high fat fruits, but all fruits contain carbohydrates.

    @Jimmy, I think you are confused about what sugar is. Sugar (glucose) is only a carbohydrate. It is the smallest form of a carbohydrate. The problem is not with eating sugar. It's nearly impossible to completely avoid sugar. The problem lies with eating sugar alone, i.e. soda or baked goods. When this sugar is digested it immediately floods the bloodstream and the body has a hard time keeping up with this. However, when eating a fruit (which contains a fair amount of sugar) you are getting fiber and other nutrients. This helps slow the carbohydrate metabolism and allows to body to digest the carbs steadily, instead of all at once.

    Imagine wanting only 15 cents in nickels, but you have a quarter. To get the nickels you have to breakdown the quarter into smaller parts--giving you 2 dimes and a nickel. To get the last 2 nickels one of the dimes must be broken down into 2 nickels. Now we have the 3 nickels we want. This is a slow process that happens over time. This is equivalent to consuming sugar from a fruit.

    Now imagine the same scenario, but instead of having a quarter you have 5 nickels. That's more than the 3 nickels we want. We have already met and surpassed our goal. This is a very fast process and nothing needed to be broken down into smaller pieces. This is equivalent to consuming sugar from a soda.

    Adam , I think you got a bit lost in translation.
    His intention was to say that sugar is fat and carbs as it is basically a 50/50 split so it is neither one or the other but both the same time . Coconut, arvo , banana etc are biased in there make-up and are listed accordingly.
    If a horse was half black and half white you would have to say the horse is black and white.
    If it was a black horse with a white tip on its nose it would for most intents and purposes still be called a black horse.

  5. Guest

    I agree with is main point, that we shouldn't be eating as much sugar. But along the way, he lost me with a lot of inaccuracies. He claims, for example, there's no food in nature that has both fat and carbohydrates, and gave coconut as an example, claiming it has no carbohydrates. In fact, half a cup of shredded coconut has 12g of carbs and 27g of fat. A lot of other foods have both fat and carbohydrates too - such as milk, yogurt, nuts, and seeds. He also claimed no one mixed fats and carbohydrates in the same food until the 20th century, which is also wrong. There are tons of very old, traditional dishes that have both fat and carbs in them. Mixing fats and carbohydrates doesn't explain rising obesity rates.

    Brilliant documentary. I've come to the same conclusions doing my own research but it is explained really well! Great job.

    @max: You're wrong, eliminating sugar from the diet does kill cancer cells. When carbohydrates are missing, healthy cells start metabolizing fatty acids for energy. Cancer cells on the other hand, which are healthy cells that have mutated, have dysfunctional mitochondria which are unable to metabolize fat. In other words, the cancer cells rely on glucose and without them eventually starve to death. Look up the German biochemist Otto Warburg, he made this discovery in the 1920's.

    "Sugar is the only food on the planet that is both fat and carbs at the same time. Olive, avocado. There is no food stuff on this planet that has both fat and carbs at the same time" Nonsense. Just look at nutritional info for avocado or olive. Both have bit of both, carbs and fat. This "documentary" has lost its credibility after this statements, not worth your time.

  9. max

    I doubt sugar is the real problem. Sugar is a fuel and found in whole foods like fruit and vegetables. The problem is never a simple as just labeling one ingredient. More likely the problem has less to do with sugar and more to do with the slew of unreadable ingredients that accompany sugar in processed foods.

    It is also a known fact that sugar does not cause cancer. Cancer cells need glucose to thrive like any cell, it's just that they need more of it because they grow more rapidly than healthy cells. There is no cause and effect however to suggest that eliminating sugar from the diet kills cancer cells.

    The subject got to include the culture shift directly affected by the modern conveniences of automobile, TV and PC, etc. Transportation and communication have altered human activity and people burn less calories due to the progress and development these delivered.

  11. Blaice

    Well done overall, but yeah, little emphasis on just eliminating fast food completely, and only consuming whole foods with LIMITED ingredients (if processed at all). If the industrialization of food never happened after WWII the obesity rate would be a fraction of what it is now. He did an excellent job not bastardizing all carbs, but rather focusing on fructose and explaining how glucose is necessary. I do believe that more about food physiological effects should have been mentioned though. Such as, phytochemicals bound to carbohydrate structures that induce healthy physiological reactions, but fiber is a good enough summation I suppose, and of course satiation is necessary for a healthy lifestyle and coincides with such.

    Lustig is a grandstanding alarmist, claiming sugar is causing “the biggest public health crisis in human history. It’s bigger than the bubonic plague, the flu, and AIDS.”
    (The Black Death killed around 40% of Europeans; the 1919 flu pandemic more than were killed in WW1, 80-100 million.)
    He says, “Sugar is the most destructive force in the universe.” The universe?!

    1. Paul Mitchell

      Lustig is not "a grandstanding alarmist". I think you misconstrue his metaphors and need to actually alert people to this actual crisis. In the same way that many chemicals have not been tested for long term affects on human health and are now slowly and insidiously starting to have extremely negative impacts on ourselves and the environment, so to the effects outlined in this
      video are slowly but surely progressing to huge proportions.

      Comparing the overall population of people worldwide
      only a relatively few number of people are and have been effected by the Aids epidemic - proportionally speaking.
      However, the obesity described in this video is all pervasive - I've lived and
      worked in Asia (China, Japan and Korea) and Europe and visited quite a few different places in Europe; as well as visited Africa. Of course live in North America. I see the same thing wherever I go - even in countries where people have always been known for usually having thin, small statures among the general populations of people - but things are different from what they used to be.

      When I was a young person 35 years ago only very occasional people were obese or overweight. Today It is rapidly becoming the exception - not to be obese or at least overweight.
      They've even started to glamorize obesity in the fashion, entertainment and
      model industry (because that is where the profits are) - if
      the majority of the population are overweight today then they will advertise
      and market to appeal that portion of the population - playing on their emotions
      rather than the neocortex of the brain (logic/common-sense). it is becoming the
      "Norm". It is an epidemic.
      The pure scientific evidence offered in this video presentation is not open to emotional debate or shame-based wishful thinking.

      Metaphors? I think you mean, hyperboles. Anyone using his OTT language has forfeited his credibility.

  13. Lz_erk

    Lovely stuff, and maybe the most informative movie I've seen on the subject, but it's hard to pay attention to someone who follows up "we can't just control behavior [because it's an individual complex biochemical system]" with "oh, but we should regulate the hell out of it."

    There's nothing in here about how the ag industry has been locked into a vicious cycle, and nothing about how we might convert the massive monoculture infrastructure to something better. You can skip the last 15 minutes if you aren't into political propaganda [from the left, if that matters at all]. I'm a firm believer in voting, but if you really want to make a difference, go plant some fruit and nut trees. Politics and corporations will get the message by the time you start cracking your walnuts.

    Edit: oops, there's more info at 54:00. /rant

    This could have been kept very "sweet" and simple eat whole fruits and raw vegetables thereby getting all the fiber and nutrients needed and exercise! end of story....carb the F up! eat 10% healthy fat.

    "For decades that 'calorie is a calorie' myth was all that was being taught. Gradually, research has proven that, like everything about the human body, nothing is that simple. The concept of losing weight: Burn more calories than you take in" is also a very simplistic way of looking at things. There are so many reasons why people can or can't lose weight, and much of it is out of people's control.

    If there is one thing we need to learn, it is that our bodies are hugely more complex than we ever could have imagined.

    For years, who knew the dangers of sugar? We grew up eating it in many shapes and forms, sugar laden goodies were given us as treats, and Halloween became the sugar fest of the year. It's no wonder our bodies started going crazy. :(
