    Alot of people can misunderstand this and put all their reasoning for not able to lose weight on 'genetics'. The choices we make do matter to our health and waistline; our actions do have consequence. They should clarify that this is extreme dieting.

    losing weight doesn't “damage” your metabolism. But because of theadaptations your body undergoes in response to fat loss (to prevent that fat loss, in fact), 'energy out' for those who have lost significant weight will always be lower than for people who were always lean. -quote from percision nutrition i got. Can someone tell me if this is correct or not?

  • Robin Lillian

    Calorie restriction doesn't work--even if you lose the weight slowly. You will still gain it back. The best thing to do is to eliminate processed food, cut down to 100 grams or less carbs/DAY (equivalent of 4 slices of toast or less), fatty meat & butter are good for you, unlimited vegetables, and cut down on sugar. Above all, don't starve yourself. Fruit juice has almost as much sugar as soda, and too much sweet fruit is bad news if you tend to gain weight. You should not be eating more than six teaspoons of added sugar per day tops, and probably less than that. Exercise is good for you, but won't necessarily make you lose weight. Fat people who exercise live longer than thin people who don't.

    "Genetics" - yeah, metabolic difference definitely can't be offset by muscle mass and adjustment of stress and hunger hormones. That statement wasn't wrong, just extremely misleading. I know dozens of people who lost weight years ago and didn't regain back because they track their macros (which is easy).

    He studied the obese, hardly your typical population. Other studies point to metabolic adaptation too but it differs from person to person, and your avg joe isn’t adapting a crazy amount that cant be overcome. Not everyone can be thin, but most can be thinner than they are now.

    Yeah, no! You cannot gain weight if you do not overeat and exercise. It's thermodynamics. You cannot create mass out of thin air. So what if your metabolic rate drops (by the way 2000 calories/day is not low, it's normal). Just don't eat more than that. So it IS about willpower. I don't care if you drop to 1500 just don't eat more than that. Oh, it's hard, I know, that's where willpower comes in.

    Just so everyone knows, I'm assuming this is ONLY referring to losing weight too fast thorough extreme diets. If you lose weight slowly, u can achieve your goals.
    That line at the end about generics REALLY makes it seem like you should just give up, but you should not

  • Jordan the Shitlord
    Jordan the Shitlord 6 months ago

    changing your diet is gonna do much more to help you lose weight than exercise will. you can eat whatever you want and be healthy; the key is how much of those fatty and sugary foods you eat. keep track of nutrients and that'll help you most.

  • Robert Silvers
    Robert Silvers 7 months ago

    This MD is generally wrong. Once you reach your target weight, you do not need to continue the extreme activity and low calories because you can end your deficit and go into a higher amount of calories that maintain your weight. Is this fewer calories than before? Sure, but you are so much smaller that you don't need as many calories to be full.
    He also said most of the difference in people's weight is genetic. That is also obviously not true because people were not generally fat until the 1970s. That proves it is diet based - mostly how much sugar you eat in convenience foods.
    If you put a thin person's brain into a fat person, they would lose weight and keep it off. It is all about choices.

    Please stop lying. Everyone can be thin but its about loosing weight healthy and changing what you eat. You can't go on the biggest looser loose weight and than go back to big macs. Also less than 3% of people are affected by genetics im weight loss. It's parenting, a child's diet reflects their parents.

  • Russell Branjord
    Russell Branjord 11 months ago

    Anyone who has truly struggled with obesity and dieting understands what he's saying. It's redeeming to know that there was a reason beyond will-power of why my dieting failed. I'm going on 15 years of my transformation by eating at a deficit for 6 days a week with a surplus of calories the other day. What this does is deplete glycogen and force fat to be burned for energy and then re-stores glycogen before leptin is affected and begins to de-regulate my metabolism.

    The study done about the show 'the biggest loser' was so flawed that it can't be used as any sort of proof other than 'you CAN lose wieght'. The majority of the contestants go back to their old eating and exorcise habits, but those who kept the diet, exercise up and regularly weighed themselves didn't gain the wieght back because they didn't go back to eating like pigs. Like this whole episode isn't helping anyone

    Same thing with gyms, muscle mass is highly genetic, and those strong men in protein shakes you buy are either genetic or use steroids.


    And now you can pay thousand of dollars to have a thin persons bacteria put into you and will help lose weight without physically cutting out the fat

    By maintaining a high protein intake, proper portioning (to caloric need) and following an appropriate workout regiment anyone can become fit and healthy. Ref Dr. Kim university of Toronto, protein synthesis and athlete protein intake review study.
    You can't change your body type, but physique and health can almost always be changed for the better. What this video is saying is that the extreme dieting seen on the biggest losing doesn't work, the human body is an amazing machine, if you treat it right amazing things will happen.

    You see kids, genetics explains most weight differences between people. This is why we had the same obesity rates 100 years ago that we have today. You know those pictures of "circus freak" world's fattest men from the early 1900s that just look like average Americans today? That's just propaganda paid for by the fitness industry. We've always been this fat. Calories in versus calories out is a lie and you should just give up.

    why not just do it at a healthy rate, cut back sugar, include fruits and veggies, work out an hour a day, and don't eat too much before bed time? Everyone's different and it may take longer due to various body issues and you may not shed pounds like a snake, but you at least will have more energy and your organs will be healthier.

    Then there's the people having problem with gaining weight. My sister and I have powerful metabolism's.
    For example, she ate four whole pizza's [ not slices, whole pizza's ] and was still hungry. Didn't gain anything from that.
    People look at that and say "Oh you're so lucky to have that" but it's not as great as people think.
    For the average person's grocery bill where I live, they spend $200 at most a month on food.
    My sister and I spend $600 AT LEAST on food a month. That's not together either, that's $600 each and the sad part is, my sister is actually losing weight still. She's so thin you can see her rib bones.

    You can cycle, you eat what the amount of calories your diet says, and then after some time, it could be every 3 days, or once a week, you eat what you would normally eat, it keeps your metabolism from slowing down, it doesnt completely reset it, but in long term you will lose weight and it will be easier to maintain.

    well. his point is right. i have been training for 8 years and in order to be in a shape that i want i must have to be on diet and do that exercise. so 18 hours training per day. no one can live like that. no wonder why they gained their weight back. in my case when i stop training and eat whatever like only 20 days. i already start losing my muscle and having belly.
