Adam Ruins Everything – Why Extreme Diets Don’t Work | truTV

artist’s rendering of what you
could look like. Huh? Inspired yet? Well, now,
that is… sexy. Yeah, I want to
look like that. Unfortunately,
it probably won’t last. In a few years, you could actually end up looking more or less
like you did before. Why?
Who are you? Oh, this is Dr. Kevin Hall. He’s an expert
on metabolism at the National
Institutes of Health, and he conducted
a six-year study of contestants
on “The Bigger Loser.” Hey, Sam,
while I can’t speak to how they produce
these shows, what I can tell you is
that of the 14 contestants that we studied,
80% of them regained most of the weight
that they’d lost. But why?
I don’t understand. When you work out,
you shed pounds. When you go on one
of these extreme diet
and exercise programs, your body doesn’t
have enough food
energy available, so it does burn
body fat. Right!
Very thin-spiring. Unfortunately, the body
soon lowers its metabolism to offset
that energy deficit. And that means
that you’d have to keep exercising and dieting
at this extreme rate just to maintain
the weight-loss. But on the show
we work out, like, 18 hours a day
and eat nothing. I can’t keep that up.
That’s impossible. Exactly. That’s why most
of the contestants we studied
regained the weight. Aah! Okay, all right! I’ll work
out this hard forever. Then will I stay thin? Not necessarily. One of our most surprising
findings of our study was that “The Biggest
Loser” contestants had slowed their metabolism by several hundred
calories per day, and that’s
even after they
regained the weight. So you’re telling me
that losing weight faster could make it harder
for me to stay thin? I’m afraid so. But Mandy said that
willpower was the key. Sam, if anyone
had willpower, it was the people
that I studied, and they showed that willpower
alone isn’t enough. In fact, research has shown
that genetics explains most of the weight differences
between people. So, as much as we
all want to be thin, we have to accept that
that might not be an achievable or realistic
goal for many of us. Now, who wants some fruit? (excited chatter) Bye, Dr. Hall! Whoa, whoa, whoa!
Hey, hey, hey! What’s goin’ on here?
Lunch is over! No, back to work.


  1. Who thought the doctor was Andy Cohen

  2. The only thing that will really help those who have certain "genes" would be to move to an area of the world where food is relatively hard to come by… and sugary, fatty processed foods are nonexistent.

  3. If you don’t believe this look at retired wrestlers, boxers and other weight system sports

  4. 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.

  5. In a different episode Adam said, “Sugar makes you fat.” Hmmmmmm

  6. 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.

  7. Of the 14 contestants, 80% did…
    So 11.2??

  8. 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

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


  11. 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

  12. 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.

  13. genetics aint going to be much of an issue i 10 years seriously all they scientists have to do is find a way to increase peoples metabalism

  14. Ill runin you its beacuse i cant gain weight and im slighty underweight

  15. I totally understand why people want to look great. But a long as your healthy your doing great. Exercising daily is really the best way to lose wait. But you have to do it over time

  16. I wish they had the full episodes so you could see at the end of this episode they explained you shouldn't exercise for results that aren't feasible and should exercise and eat right because it makes you feel better and improves your quality of life in general.

  17. Everyone can be thin if they lose it slowly and sustainably.

  18. Wtf This is So uninspiring… LAME

  19. I'm already knew this

  20. One word answer : powerlift

  21. So weight loss is pointless more or less

  22. The guy 'Dr Kevin hall' looks like mark ruffallo
    Wonder when he is gonna be hulk

  23. WRONG!!!! What about OMAD.

  24. 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.

  25. Kids this is why we have liposuction.

  26. How cool would it be to have Avatar Korra as your personal trainer <3

  27. anorexia

  28. Why can't I gain weight

  29. Ill change my genetics with will power

  30. You know what they say "Slow and steady wins the race"

  31. Subscribeto pewdiepie

  32. Weight or mass

  33. 👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻

  34. Choose a life long eating lifestyle that moderately healthy. You gain weight back by old habits.

  35. Thick is life

  36. Then I the doctor said I was obese. I can loose it if I regain it.

  37. 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.

  38. Adam picked the wrong expert for this episode. I would really like to see him bat a perfect "always correct" but this episode weakened his streak.

  39. Now I know why I’m fat

  40. Funny for me, lost 30 pounds from eating once a day in 9 months. In whch when i started losing weight. I gradually eat a bit more than one meal a day.

  41. The entire episode sounded very discouraging like there is no hope 🙁 either you have a great metabolism or great genetics or you are screwed.

  42. This haul got is a complete idiot. Not getting thin because of your genetics. This is ridiculous, anyone can lose with the proper lifestyle, nutrition and training.

  43. 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.

  44. 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

  45. Jsut diet and exercise in a moderately way isn’t hard ok it is but it’s worth it.

  46. 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.

  47. Jeff Cavaliere wants to know your location.

  48. not everyone can have a model like body, but pretty much everyone can lose weight and keep it off. just stop eating sugar, bread, and pasta. you will lose weight. lazy fucks.

  49. I eat most of what I burn, it keeps a high motasium.

  50. Remember the old saying folks, slow and steady wins the race.

  51. That dude looks like trap

  52. Because Adam says so

  53. Wanna get slim? Start Smoking weed and wait half a year lol

  54. Try this terrible idea: slowly eat more calories and sugars within a month then how back to your original diet for a week and you should lose weight

  55. Poor Sam.He will be fat forever.

  56. What's the source on "Research has shown genetics explains most of the weight differences between people" ?

  57. but… what about those people who fat genetically ?

  58. 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.

  59. "unrealistic" why?
    if you don't eat enough eventually will loose weight. Period

  60. You can't spell Diet without DIE.

  61. And this is why my mom always calls us( my family) to dinner so we run up the stairs for excersize

  62. now you know kids it your mom and dad fault your fat

  63. "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).

  64. If you work hard you can raise your metabolism

  65. But I wanna be fat

  66. Great video! Have a nice day!

  67. so crisper is the key to the perfect plan and some of us in addition to our control and pysical activity are just lucky well i fell less but still criticatl of others

  68. 0:04 That photoshop is so unrealistic

  69. 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.
    That Sugar Film:

  70. what about muscle mass to increase metabolism

  71. This is wrong, sorry

  72. Tom Hanks got diabetes from the weight he lost.

  73. Wow this is triggering for eating disorders 😂

  74. 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?

  75. Want to loose weight and get paid for it? Well there is a solution:

  76. 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.

  77. Why not edit DNA to make us be thin

  78. Don’t make it seem like being fat is ok. It’s incredible unhealthy. People can loose weight and be healthy.

  79. Anyone can lose weight

  80. I heard that occasional cheat days help your metabolism adjust to the extreme diets. Is that true?

  81. ..sam, how many fatty melt shirts do you have?

  82. Might as well tell my friends

  83. “One study” :its all genetics
    Every body builder on this planet: nope, it’s a combination of hard work and constant discipline……. but don’t forget trenbolone , stanozolo, human growth hormone and pure testosterone

  84. I cut from 185lbs to 165lbs over 3 years.. now i am absolutely traumatized by the experience and make sure to never gain a single pound back. Just avoid the weight gain and you wont have to kill yourself in the gym.

  85. I've been waiting for Adam to tackle the diet industry! THANK YOU

  86. i don t believe it diet it healthy even my doctor advice to loose weight and it works sorry adam

  87. Lol
    Adam cannot ruin lemonade for me

  88. Ok am I the only person who gets pissed when ppl use percentages for small numbers? "Out of the 14 contestants we studied 80% regained weight" 80 percent of 14 is 11.2 what the hell?

  89. I am thin already so i wont work hard for this but i will exercise to make my self healthy

  90. The health industry is a fraud. If you want to live healthy, cut back on meats and carbs and eat veggies and plant based protein.

  91. For people who want to lose weight gain muscle which raises you metabolism even if you are a woman.

  92. If You Are A Fat Person, And Want To Lose Weight, Listen To Me First. Losing Weight. It May Be One Of Our New Years Resolutions, And We Are Trying To Do It Almost Every Day. Yet, As I Say It, Some Of Our New Years Goals Can’t Be Reached. Companies Pour Millions Of Their Dollars Into Advertising For Weight Loss, Whether It’s On Your Magazines, Newspapers, Radio, Billboards, Or TV Commercials. In These Ads, They Usually Show A Sexy Hot Model With A Bikini, With Them Telling Their Story Of How They Lost Weight, And How You Can Do It Too. They Also Start Exercise Programs On TV, Which Had Been A Thing Since The Low Fat Era Of The 80’s. Yet We Are Eating Nothing But Vegetables, And Going To The Gym Every Week, And You Soon Realize That You Still Regain Most Of That Weight, And Still Don’t Look Like That Sexy Model On That Magazine. In Truth, Companies Don’t Want To Tell You This, But That Sexy Model You Have Been Looking At, May Be Photoshopped. As Adam Said In His Low Fat Video, Everyone Has Been Eating Fat For Almost As Long As Modern Humans Had Existed, Around 200,000 B.C. Around That Time, We Learned How To Cook Food With Fire, Which May Have Have Started Human Evolution And Intelligence. Until 10,000 B.C., Most Starving Humans Were Hunters And Gatherers, Which Means If They Had To Get Food, They Would Have To Use Their Stealth To Kill The Wild Animal For Food. It Was Hard Back Then. Suddenly, In 10,000 B.C., Most People Had First Learned To Grow Crops, Starting Agriculture. Because Of This, The First Civilizations And Cities Were Established Around 3,000 B.C. Now To The Real Point, As Adam Said In His Low Fat Video, The 1950’s Were A Decade In Which It Saw The Increase In A Once Rare Disease, Known As Heart Disease. The Heart Attack Eisenhower Suffered From In 1955 Encouraged People To Fight This Heart Stopping Monstrosity. But, The Sugar Industry Had Other Ideas. In The 1960’s, This One Very Popular And Very Kind Of A Jerk Scientist Blurted Out For No Reason That “Hey All Of You! Fat Causes Heart Attacks Much Like Mexicans Cause Everyone To Smoke Weed Everyday!” And The Crowd Was After Him, Much Like A Girl Chasing After A Boy Band. Suddenly, BAM! A Very Less Popular, But Actually Correct Scientist Said “Sugar, Sugar, Sugar, You Guys Are All Wrong, Sugar Is The Culprit For Some Reason” The Public Mocked Him So Hard, Even Harder Than Anyone’s Parents Would Spank A Child. The Same Decade, The Government Convinced The Sugar Industry To Downplay The Dangers Of Sugar, And Shift The Blame To Fat. By Paying Them Dat Moolah. In 1972, That Very Unpopular Scientist Appeared Out Of Nowhere Once Again, To Show A Random Graph Showing The Rising Amount Of Diabeetus In The U.S.A. But BAM! He Was Gone In An Instant Due To Mockery. In 1980, The USDA Finally Concluded That Many Americans Needed A Low Fat Diet. This Started The Low Fat Diet Craze In The 80’s, And Continued In The 90’s. And Everyone Stayed Skinny Forever The En-SIKE!! Obesity Commences In The 2000’s, The Food Pyramid Is A Fraud, And Rising Heart Attack Rates Still Continues To This Day. How Did It Get This Way? You See, Cutting Out Fat All Together Makes The Food Less Appealing, So Companies Add Something Called Lots Of Sugar To Make It More Tasty. You See The Problem There? Now For The Message. Today, Fat Shaming Is A Thing, And It’s Happening To Millions Of Us. Fat Shaming Prevents Us From Speaking Out About Our Own Fat, Which Is A Big Issue. It’s Also A Form Of Bullying, Leading To Suicide. But No Matter How Much If These Things Affect You, Don’t Listen To The Big Corporations, And Listen To Your Heart. You Have Your Own Right To Speak Out About Your Own Fat In Public, And You Can Say It Out Loud For Everyone To Hear. You Have A Right To Show Your Own Fat, And Say To The People That They Can’t Lose Their Own Weight, Because They Have No Issue Going Through Fat Shaming, And They Can Go Through This Form Of Bullying Together. Together, We Can Stop Fat Shaming, One Bite At A Time.

  93. Sooooo, people that have good genetics are hipcriks

  94. Being fat is a choice as even your metabolism can change and dieting isnt the answer cutting back how much you eat tho is key find things that help you get your mind off of it as your basically killing your micro biome by reducing how much sugar you consume

  95. i dislike everyone who works with adam,i just do..their faces annoy me, alas adam is my favourite:D

  96. I feel this episode was a not well balanced (like many peoples diets). It warns about the dangers of fad diets and extreme exercise programs yet it practically ignored the benefits of a healthy, well rounded diet and the importance of moderate, consistent exercise.
    I'm a former nurse and personal trainer. The goal of a trainer is to teach you the way to live a healthy physical life that fits well into your lifestyle. You'll know you have a good trainer if you need them less and less.
    Maybe touch on that a bit Adam.

  97. Actually cheat days have benefit because they reset the metabolism

  98. Machio-san: You can snack throughout the day and lose weight, however just keep it light and eat only when you feel a little hungry. Try and keep those calories in check…ranges of 100-400 calorie snacks… remember don't go overboard your goal is to get fit. It's recommend to have at least one real meal, with some salad and greens that those snacks don't offer. Also allow yourself a cheat day snack on whatever you want and have a decent two meals so your body doesn't think your starving and lose energy or come down sick. Remember starving yourself doesn't work, you may see fast results, but when you do eat your body considers its self in starvation mode and turns more calories to fat than usual and causes a rebound pretty quick. Don't forget to consult your doctor before dieting! Just be sure to get some exercise between meals and stay healthy! Yes, I know lotta people won't know this reference.

  99. why does this have to be so fat phobic?? why?

  100. body diversity is real people
