Prof. Robert Lustig - 'Sugar, metabolic syndrome, and cancer'

  • Published on May 15, 2020
  • Robert H. Lustig, M.D., M.S.L. is Professor emeritus of Pediatrics, Division of Endocrinology at the University of California, San Francisco (UCSF). He specialises in the field of neuroendocrinology, with an emphasis on the regulation of energy balance by the central nervous system. His research and clinical practice has focused on childhood obesity and diabetes. Dr. Lustig holds a Bachelor’s in Science from MIT, a Doctorate in Medicine from Cornell University. Medical College, and a Master’s of Studies in Law from U.C. Hastings College of the Law.

    Dr. Lustig has fostered a global discussion of metabolic health and nutrition, exposing some of the leading myths that underlie the current pandemic of diet-related disease. He believes the food business, by pushing processed food loaded with sugar, has hacked our bodies and minds to pursue pleasure instead of happiness; fostering today’s epidemics of addiction and depression. Yet by focusing on real food, we can beat the odds against sugar, processed food, obesity, and disease.

    If only I had known now 40 years ago, I could have avoided a lot of health problems. At least I learned this last year and have turned things around. I've lost 65 pounds and no longer need blood pressure medication.

      Can you imagine if FDA suggested people get healthy during covid lock downs? Not only would we have reduced death substantially, but we would have also lowered blood pressure, diabetes, mental health... but admitting sugar is a drug & should be regulated would break the SAD (Standard American Diet) hold the food industry has on people and would lead to millions of dollars in losses, not to mention other countries not importing our food anymore. If only real science played a roll in our science these days...

      @Karen Burden I am 52, Stage 01 Type 2 Diabetes. My Endocrinologists are aware of these studies. She is a young doctor who studied Medicine in Pakistan and got her PhD at NYU.
      She put me on mild Intermittent Fasting (8:16 three times a week on alternate days) and on very strict Paleo Diet. After 6 months my med was reduced to one 500 mg Metformin after lunch (my biggest meal), my Lipid Panel went to normal and I lost my love-handle fat. My fasting glucose level has been perfect for almost a year. -- It is, however, truly hard work. Because I got to give up things that I’ve been enjoying since I was a teenager: Beer, gin and Wine…..

      @The Prophet Food industry profits, since you overeat. Medical industry profits, since you now have a chronic disease.

      I pick the "not sick" option. In the US that severely cuts down on what I can actually eat (in Europe it's easier, bread isn't off limits!)

      Since I get sick from US milk (not lactose intolerance) and pasta (I don't know why, I just get really sick), it comes down to rice, eggs, vegetables, and occasionally organic meat and milk.

      The guilty treats are salted potato chips and McDonalds without sauces, buns, and any sugary item. I know, trans fat and french fried, but we aren't all saints.

    My heart is bumping and my eyes are wet. Thinking at my oncologist saying. No, sugar is not the reason for cancer since the body produces glycogen as you don't eat sugar.
    This is the situation when patients ask if cutting out sugar of the diat would have positive effects.
    In my case I encounter so many doctors who stuck with the book they read back then in medical school. They have not developed and keep on talking shit. Yes it takes effort to keep being updated.
    I am so sad!

      @Coobroobloob It's a drug... with the same brain hijacking, same cravings & same withdrawals, just not as incense as some drugs / alcohol. As long as you stay clean, you don't think about it. Let some it in your system & all of a sudden you're thinking about it & craving it again. Much easier to say no once or twice than have to get it out of your system again. I was strict for years, but lost too much weight. After not being able to gain any, I decided it was time to have sugar again. 4 months & 14lbs later, my brain is way foggier. Being off sugar and back onto coconut oil for healthy fats, my brain is starting to clear again. NO MORE SUGAR FOR ME!!

      I will never give up all sugar entirely, but I do need to cut back to very little. I do well and then cave in. Get back on track pretty quickly. My brain hijacks me and convinced me it's fine to have "some". I need to save it for special occasions like birthdays. I just need to be strong through those moments of craving.

    Dear Prof Lustig, your lectures are always mind boggling and this is one of them I was waiting for! Being a diabetologist myself and blindly following so called best practice guidelines for 28 years, I ended up asking myself, whether I am a victim or partner of greatest medical science scam that is going around! I still do not understand why Hippocrates old saying " Thy medicine is thy food and thy food is thy medicine" is ignored by our medical fraternity. Believe it or not most of my longest surviving patients are on Low Carb diet, I am not sure about their fat intake, despite my advise to be liberal on saturated fat! I would be grateful if you permit me to quote and use some of your slides for educational purpose.

      avoiding high intakes of sugar, and processed toxins as vegetable oils is key to live better, longer and much much healthier. Avoiding crop pesticides will definitily help as well. Ecological food. Its REALLY hard avoding all these daily enviromental toxins we humans produce and put on our food. It shouldnt be. Its sad that its not talked about or brought up more often mainstream

      Soft drinks being a driver of obesity isn't surprising at all. Syrupy and sugars drinks have minimal effect on satiety, most peoples bodies won't perceive them as food, but they have alot of calories and they raise insulin (leading to fat storage after a meal).

    2:50 - cancers that seem to be associated with obesity

    7:25 - then how come the normal weight people are getting diabetes as fast

    8:50 - MHO

    29:50 - where that fat come from ( liver fat )

    45:00 - cancer

    48:50 - glucose is absolutely vital for cancer cells

    50:45 - mTOR

      They need insulin and perhaps their pancreas can't keep up because of the high sugar diet we are all eating. Type 2 diabetes is not about being fat although that is often a symptom. Our pancreas has have to make an inordinate amount of insulin to keep our blood sugar in check. Many people are walking around with high insulin levels and they do not know it

    This was absolutely a wonderful presentation! We definitely need to take our health back into our own hands first of all, by re-educating ourselves and our children, about nutrition, and better understanding of how and why our food choices matter so much, for preventing so many of the chronic illnesses, cancer and sickness in general.

    The second thing we need to do is collectively stop buying poisonous, toxic, processed foods, petition the food production companies to improve, or loose our business, to the increasingly new, small food companies, who are rising to meet the demand of what more and more people are wanting, which is real food, organic produce, not the GMO, chemicals, preservatives, lab made crap that’s been making so many people sick and die!

    While we won’t hold our breath waiting for the food industry to catch up, we should still hold them accountable, and as the saying goes, money speaks volumes to big corporations, big pharmaceutical too!

    The more we learn, share with others, the better we can prevent and heal, by buying from local farmers, helping small farms stay in business, since they have been almost completely wiped out by big factory farming, only concerned with their bottle line profit, and unfortunately has been allowed to use poison pesticides and insecticides, GMO’s.. controlling farmers seeds as well! The people of the US has not been represented by the majority of our many government agencies, and while big corporations, banks, and our government has become rich off of us, they have too much power, control and are right now in our face showing they don’t care about our country, and will do as they please!

    Who is sick and tired of being sick and tired, seeing loved ones suffer, die too early, and paying so much money, working so hard for crappy food, crappy health care and paying more and more for it all? We need to learn container balcony gardening, back to basics with learning things our great grandparents learned. I think realizing how much better people start to feel, while making healthier choices and taking responsibility for our own health more, will bring confidence and encouragement to others, as they see how much improvement in their health they see they can create! I know I’ve been motivated by others, who are proof, living, whole, non toxic food can be our medicine!

      @Ae Norist Nonsense. Lustiq is trying not to throw the baby out with the bathwater. It's a good tactic. But clearly if fructose is poison - you would do fine with minimal amounts of fruit or other high fructose foods.

      It's the same thing with alcohol. No one needs to drink alcohol in ANY amount. You would do 100% fine skipping all booze.

    I just found this channel and have been watching all the videos during a rheumatoid arthritis flair up.

    I found this gentleman after being medically retired from a very physical job which I loved. I felt sorry for myself and ended up putting on tons of weight. Watching the effects of sugar, fast food, carbohydrates I gave up everything with an ingredients list…..six years later I went from 196 lb to 130lb with no problem. Never put back any weight.

    Sadly I still have RA because it is genetic but the flair ups have reduced in intensity and timing.

  • Umesh Chhikara - Sports Scientist

    Loved it. Thank you. In the Indian context....you are right when you say we are not obese and yet we have 11% cases for diabetes. Wonder why? Depending on which part of India you are looking at; we are ingesting sugar at different times with different combination but not with meals. This to me is the main differentiation.

    i) North India: Not lean but not obese either: No sugar (fructose) with food and it comes in the form of fruits, milk and tea at different times.
    ii) East India: Extremely lean people: Hog on carbs (mostly boiled) but quantity is a lot higher & some fish/chicken as well. Sugar intake is in the form of tea, biscuits etc but again not with meals.
    iii) Western (Gujarat mainly): Significant number of Fat people: Add sugar in their food. Love sugar but otherwise have low appetite - eat less food overall as compare to other regions.
    Iv) South India: Strong mix of lean & little abdominal fat: Use lot of unsaturated oil in their high carb food. Sweet tea and other sweats.
    So yes, there is a sugar intake but since it is not clubbed with food; it doesn't make the person obese. But sugar is sugar....The Diabetes and Cancer! A lot of us become insulin resistant for sure and hence we are likely to get it either being obese or staying normal. In contrast if you look at poor people; their main source of energy is 'sugar' via tea. Very high sugar and even though they burn it in the form of energy, they don't seem metabolically healthy either in my experience dealing with a few over the years.

    Here is my hypothesis:

    It is the combination and it makes it worse if you are either high on carbs or fat and mixes it with sugar. One of the main reasons for obesity is 'Sugar' in America which is ingested mainly via soft drinks & sweet tea with the food.

    An incident worth quoting: Once I was ordering food in a small restaurant at the counter in US. After I ordered the food, the girl at the counter asked me what drink? I said 'nothing'. I still can't forget the look she gave me :)

      All would have been well in India while they just lived on the rice carbs that produced glucose until the western diet came along and introduced the drinks in the fridges and of course just plain old sugar. But Indians and, for the most part, Asians are not designed to get fat the way Europeans do. I don't think it means they can't but they would have to work at it. Sit on their but all day or something.

      In 2013 I went keto and knew SE Asians could eat rice and fruit in large amounts and stay thin. In recent years US fast food chains have flourished and SE Asians are getting obese. You focus on combining is a good one and you're not alone.
      I think fructose/sugar = the biggest problem.

    Started Keto again yesterday. ALREADY FEEL BETTER!! Rebounded 48 lbs from a 105 lb weight loss in 9 months. So sad, but I'll be smart this time. Long IF is not for me. I pushed the limits and really weakened myself.
    A -fib, severe hair loss, general total body weakness resulted. Thin but weak...and I ate well, plenty of protein I thought, but after reviewing my daily diet Journal I see that I was adding carbs in justifiable ways, chocolate, red potato, pinto beans...SOME of us are Insulin resistant (severely) AND hyperinsulinemic TOO. This problem is all about behavior. I need to be grateful keto works and revel in it! ALSO, Leaky gut is REAL and I will address it earnestly this time around. God is 👍 good. **THANK YOU GENTLEMAN for teaching us applicable science so we can heal. 😘😁

    This information is so helpful and very informative. You should see what they feed some of those poor people living in nursing homes.

    For the benefit of readers with auditory disability and to help remember the bitter facts, here are the key points about KILLER SUGAR:
    * Sugar consumption correlates with obesity & cancer.
    *Obesity is associated with cancer development. Metabolic syndrome due to insulin resistance is the cause.
    *Fructose possesses unique metabolic characteristics which promote cellular damage.
    -- De novo lipogenesis, fatty liver, Maillard reaction & cellular aging
    *Sugar is an independent risk factor for metabolic syndrome.
    *American Heart Association advices that we should cut down on sugar.

    Thank you Prof. Lustig & Low Carb Down Under!

    Many thanks for making this public. I had 107 kg weight and this was too much. I reduced sugar and reduced bread and ate more other things including vegetables, meat, and butter. I cooked myself and lost 10 kg and kept this for over 10 years.
    The main thing in my case was Insulin. After I changed it i did not become hungry short after the meals anymore, except we ate outside of home.
    Every day I cooked the meals I took with me to work when changing my life style. I did not know how much sugar they put into the meals.. (In Germany lunch at about 12 am is the main meal.)
    I ate really large portions and my collegues were astonished when I said I want to lose weight. But I lost, just avoiding sugars an most of other carbon hydrats.
    At first my wife was astonished, because I put lots of things on one slice of bread rather than eating 3 or 4 slices as before. Two years ago I started to bake the Bread miself, and my wife liked it much.

    Really interesting lecture and I agree with much of what Dr Lustig puts forward. He has a very unique insight of diet and does show that even if you find low carb difficult that cutting sugar additives will massively improve your overall health. Especially with his study on the children within his practice. The dramatic change in their health not dropping carbs or starch just the added sugar, genuinely was astounding. However, I do wonder how much more dramatic the markers would have been if he took it further- even with a select few of his patients- with a low carb diet of maintaining the same number of calories and whether the results in would have been even more dramatic. He seems extremely attached to maintaining his view on low fat guidelines despite the mountain of evidence which disproves it.

    Many in my family caught Covid. Most of us are keto and eat organic or high quality meat/eggs/veg. And we did very well, slight fever for 2-3 days for 30'sh yr olds and the 55 yr olds had slight fever for 5-6 days. The fatigue lasted longer for the healthier eaters. (One 55 year old smoker/sugar eater friend was given HCQ and felt much better next day!) My 81 year old dad never sought medical help, just slept alot , fatigue for 3 weeks (fever/chest congestion). Mom 77 yr old took care of him and never caught it. (She suspects she may have had it 6 mo earlier.) Mom does Keto. So, does it have a 6 mo protection antibody? At this point, I know a few hundred of people who survived with mild symptoms. The few with diabetes who turned into pneumonia also got better much quicker with HCQ or Remdesivir (the cures). Now I'm seeing the pattern -- the Neglect from Hospitals/doctors are causing the DEATHS of Americans-- the with holding of the cures is nothing short of Neglect!

    This lecture is PACKED with good info.
    My conclusion is that I'm SCREWED because:
    - I'm poor but I have access to A LOT of fruit.
    - I don't eat gluten and organic corn galettes are the cheaper than gluten-free bread.
    - While fighting H. Pylori with the strongest antibiotics on the planet I acquired SIBO H2S so my veggies options are much narrower.
    - I quit sucrose years ago when 2 rare cancers were found in me but I didn't eat as much fruit as now.
    - I eat plant based. Not only I cook it fresh every day I also spend a lot of time eating it. Food is one of the few remaining forms of satisfaction & relaxation.
    The main meals are probably OK.
    It's my snacks I'm concerned about because they are very often just plain fruit laid on corn galettes.
    Dr Lustig also mentions corn-fed beef is a problem so I assume Corn itself, regardless of being organic.
    - - -
    I assume the fibre in fruit changes little to nothing of the evil consequences of the Fructose molecule here presented. Am I wrong?

    • Én egymagam
      Én egymagam 21 day ago +1

      You're wrong, I guess. Fibre is the most important piece of fruits. What is more: you can eat fructose-free fruits with a good amount of fibre. Those are called raw vegetables. :-) Organic sauerkraut is my favorite snack.
      No sucrose: great point. I put pure glucose powder into my coldstart morning coffee. Sweet, but zero fructose.
      Take care, avoid fructose.

    Years ago a doctor here in Sweden , stated that I have fat in my liver. No more ! Well he said that can be reduced if you loose weight. !!!!!! He did not give me an idea of how dangerous this is. He did not talk diet. He did not schedule an other appointment. This was in a hospital. My own doctor just told me that he has a belly too- as if I did not notice. Now I take matters into my own hands. I should also use said hands to slap these doctors- if only it would help. Thanks goes to Dr Lustig and other docs of low carb / carnivore / anti sugar . Don’t do legal drugs - don’t do fructose .

    Oh yes- I offered to send a s... load of videos to my doctor . He said he didn’t have time for that. I said you don’t have time not to see these videos - because everybody will be sick in the future if we continue as before. Again : thank you dr Lustig( and you are even “ Lustig” in a German sense )

      Sensible consumption of fruit is ok. The fructose is little and the fiber slows its absorption so the liver has enough time to process it. Fruit juice loses the fiber and is not okay. Processed foods’ sugar is where the harm is.
