Dietitians Debunk 18 Weight Loss Myths

Dietitians Debunk 18 Weight Loss Myths

Business Insider asked three registered dietitians to debunk 18 of the most common weight loss myths. They explain that you don’t need to purge your diet of fat or carbs to lose weight, skipping meals can backfire, and fad diets like the ketogenic diet don’t often work. Beyond debunking weight loss strategies, they explain that weight loss is not just about discipline. It’s about genetics, access to healthy food, and your relationship to food.

    I use the lose it app lost 5 pounds in two week not even hungry you really do have tons of options for food.



  2. Francis Frick on August 8, 2021 at 9:39 pm

    These people are quacks. Shame on science insider for not doing their research.



  3. Vanessa Joy Manalang on August 8, 2021 at 9:41 pm

    I just want to ask if tea also helps?

    The real reason to quit wheat is to reduce inflammation.

    Who the heck puts more than 2 tablespoons of olive oil in a pan if they are "free-pouring" it? If you’re trying to coat the pan, you would never put that much. Also, if you get the pan hot with the oil, by the time you cook whatever it is you’re making, there will be less calories added from the olive oil. I think that example is bad.

    I completely disagrees with them about keto diet. I have IBS and it’s more under control when I’m on keto 3 months out of the year. I don’t do it more then that but I do stay low carb. I was prediabetic which is why I did keto i no longer have high sugar spikes after going keto and staying low carb on the rest of the year. I also do a clean version of keto i don’t do deep-fried anything. Fasting is also incredibly easy with keto i will skip a day a week during my keto months and I don’t binge or feel the need to binge when I go back to eating. Keto really keeps my hunger in check. I bet these dietitians have never tried keto in their life and are not talking from experience.

    I almost killed myself for a girl cuz he was into skinny skaterboys, I went from 94kg to 65kg under 1.5 years 😭😭😭 I just drank water

    I wanna say something here that most people don’t really say. America is one of, if not the hardest developed country to try to eat healthy in. Even our "good" foods like bread are more processed and have more sugars and things like that in them than other countries do. In other countries, there’s stricter guidlines on what can and can’t be on the shelves of stores in terms of how healthy or unhealthy they are. Their quality standards are higher. Even our fruits here in America are not the same as the fruits in other countries because their fruits are likely to be fresher than ours. In other countries, the sizes of meals are smaller and their drink sizes are smaller. In other countries, their fresh foods aren’t as overpriced as they are in America. Of course there are exceptions and cases in which it’s flipped or there isn’t enough information to be able to compare, but on the whole America has the most amount of unhealthy food that dominates our shelves than almost every other developed country. So if you manage to eat healthy in America, I applaud you because it’s a tough hill to climb. It’s so hard to be able to afford to eat healthy – both in terms of how much time and research into items you have to do and how much the items themselves cost. It costs a lot in both time and money to be healthy in America. And if your parents managed to feed you healthy food as you grew up, please take a moment to thank them for it because that’s so amazing! My mom’s a single mom and she managed to get good-quality food for me to eat as I grew up, while also working her ass off to get me a good education, and I will never not be grateful to her for that. If your parent’s couldn’t afford to do that, that’s totally fine and I completely understand. I’m not here to bash or judge anyone, just applaud those who went above and beyond. Because that deserves recognition. So if your parents, like mine, fed you a well-balanced diet despite all of your whining, and got you to eat your vegetables and got organic fruits and non GMO milk or whatever else they thought/knew was healthy at the time, please take a moment to consider what challenges they might have faced with that, and that they overcame them for your benefit. Okay, I’m gonna go hug my mom now. Goodnight!



  9. Kanishck Tewatia on August 8, 2021 at 9:55 pm

    I really don’t get the keto hate. There’s thousands of people who have lost weight so damn fast and with little effort. what is wrong with that?



  10. Shemiah Walker on August 8, 2021 at 9:57 pm

    I like this information



  11. Ariane Paradis on August 8, 2021 at 9:58 pm

    If you don’t eat carbs your body will eat all your stored protein so your muscles and you fat storage. Then it will create ketone bodies to use as fuel. Your blood will acidify. Please eat your carbs, your whole energy cycle relies on them. Don’t believe me? Look up glycolysis and the citric acid cycle.



  12. Serane on August 8, 2021 at 9:58 pm

    Here’s another tip: cut salt as much as possible. It holds back water.
    Any time I eat a tiny piece of cake or even stevia I know that my body will not lose fat that day. It’ll gain a little bit – even the tiniest bit.
    It’s ok to cheat but you gotta be ok with the consequences.
    I’ve been on a vegetarian high protein low carb adequate fat diet for 3 months losing 0,5kg every week without being hungry 🙂



  13. Angel Flores on August 8, 2021 at 10:02 pm

    You see, I see overweight people as greedy and selfish, taking up more space and more food consumption. Because I do believe that you can be healthy at almost any weight, to an extent of course



  14. Patrice Boivin on August 8, 2021 at 10:02 pm

    time to debunk the debunkers?



  15. Lexi on August 8, 2021 at 10:03 pm

    My dad once believed a "doctor", she probably called herself a "healer" for legal reasons because it all was a total scam, told him I was allergic to gluten, eggs, and that I was lactose intolerant. He believed her and cut all of it out of my diet. I was young enough that if this had continued I could’ve actually become allergic to these things because my body would’ve gotten used to not having it in my diet. Basically, if this had continued to go on she could’ve made those things correct! She also told my dad that this specific, very expensive foot bath could cure the liver disease that both he and I both apparently had. He believed her. So yeah, you definitely don’t want to cut things from your diet entirely if there isn’t a reason to do so, especially with young children, because it can actually make things a lot worse for them in the future. I even talked with another woman who’d mother had gone to this quack when she was younger and now she’s allergic to things she never was allergic to before because her body unlearned how to digest those foods. So those sort of intense responses to small issues can cause much larger issues later on, just fyi. Also there’s no scientific evidence that I know of that backs up developing allergies by not being exposed to certain foods for long periods of time, at least not that I could find online when I just googled it, but it is a phenomenon I’d heard of from the many bad reviews of this quack that we looked at to get a judge to sign off on taking medical custody away from my dad. So no scientific proof here, just a really bad personal experience I wanted to share to hopefully save someone from living through a similar situation.

    Sadly the hero who listed all the points isn’t near the top 😭



  17. LarryKinobi on August 8, 2021 at 10:06 pm

    "Eat your carbs!", "Intermittent Fasting is bad!", and "Keto is bad!" Yeah because keto is putting all of you out of a job, so of course you say that. All carbs, simple and complex, raise our insulin levels, which is quite literally the fat storing hormone. If your keep your insulin levels high you will greatly stifle your weight loss. Keto and fasting is a scientifically proven method to losing weight. Do your research and make sure everything said is actually backed up peer reviewed research. It is staggering how much BS is spewed by the drones in this video.



  18. Superduperdproo on August 8, 2021 at 10:08 pm

    Did you hear about "Agoge Diet"? These guys deserve a medal. Their customized training and diet plan helped me change my life. I can’t thank them enough



  19. Mohammad Dajani on August 8, 2021 at 10:10 pm

    If they throw food in that trash one more time, I’m going to lose it!



  20. rommelfcc on August 8, 2021 at 10:11 pm

    Try frying with a little water, with no oil at all.
    Use the ingredients to flavour the meal, garlic, green pepper born (still fruit)
    ginger, mint, capsicums, basil, etc etc.
    If your looking for a cheesey flavour, slice brined olives (not too many, they contain alot of oil) what bring a nice salty smooth flavours to the dish, taste the foods before cooking to get an idea of what you want to use…
    Just add a little water to lift the flavors off the pan, pinch of salt.
    Don’t over cook, just enough to brown the natural sugars a little.
    The should still have some bite to them.
    Serve with some hot rice
    Or steamed potatoes bits.

    Another thing I like to make is rice paper & Nori paper wraps.
    Make a sauce like garlic fine chopped chillies, a little salt, Limon or lime juice, can even ad a little as zest might make it a interesting oh and some or a lot of crushed garlic.

    or

    homemade guacamole, make a salad you love.
    From there was a starch e.g. sticky rice, Brown rice, steamed potatoes, taro or sweat potatoes. Dry baked potatoe wedges is nice too, really give the wrap some bite.

    Method:
    Wash chop the potatoes.
    If I steam I do chilies rough cut style. Steam about 17 minutes.
    If baking, I it’s into 8 wedges, lay them skin down on a baking sheet.
    While their are still moist, sprinkle with salt, and any flavorings BEFORE baking 180C – 200C (every oven is different) for 25-30 mins rotate the tray for another 20 mins. Eat hot or cool and store in the fridge.

    Or

    Can use a sticky rice
    Soak for about 1 !/2 minimum at room temperature or over night in the fridge. Steam in a bowl sift in the steamer, bring the water to boila and steam for 13 minutes,
    Tip immediately out onto a plate

    Note: If it cools and sticks to the sift, bring the water to boil again to heat the sticky ( gluttonous) rice for 1-2 minuets, then tip into a plate

    Best choice, don’t let it cool set an alarm.

    0r

    Steamed and mashed potatoes, mix brown rice, about a 50/50 mixture
    Add some and sliced olives, a little lime, crushed garlic and anything you like.

    Next step after gathering all your ingredients, and mixtures.

    Get a large plate or chopping board.
    Place the Nori paper down

    Then will need a dish to have some water in, dip the rice paper (just get it all wet no need to soak, don’t soak!

    Place the rice paper on the Nori paper, then add your fillings, e.g. salad a sauce if you wish and mashed potatoes
    Then roll
    (No need to use a sushi mat)

    And its ready to eat, bon appetit.



  21. khatdubell on August 8, 2021 at 10:12 pm

    Was a decent video until it devolved into "healthy at any size" bs at the end.
    While bmi is outdated someone who is clearly obease isn’t healthy.



  22. Courtney Thompson on August 8, 2021 at 10:14 pm

    I’m not sure about the last point; I’ve learned that genetic and family factors make up a minute 2% or so of the total influence of a person’s weight.



  23. Robert Pyne on August 8, 2021 at 10:15 pm

    “There is no one tool that will make you lose weight”
    *calorie deficit*



  24. The Trusty Sidekick on August 8, 2021 at 10:17 pm

    Just eat whole foods, none of this processed crap. And move around, it can be exercise or just you going about your day, move around, the body is like a river, it likes to flow and move.



  25. dannes22 on August 8, 2021 at 10:18 pm

    Calories in < Calories out.
    Weight loss

    It’s not rocket science.



  26. Aljosa Lp on August 8, 2021 at 10:19 pm

    Sorry, this article is ooover simplifying most of the stuff. Related to Intermittent fasting, keto, carbs etc.. it’s not that simple. The Valter Longo’s fasting mimicking diet for example is a project with real 20 year of studies on mice and lab rats, and at the end put in real practice. Let’s go myth by myth: NO1: Skip meals, if we are speaking 5 meal a day, yes. Snacks are something that are an industry invention to sell more junk food. The three main meals are still ok, although skipping one is popular and if you gain enough calories in two why not. Myth NO2: OK. Myth 3, depends what you mean for starving. If this is reducing calories to enter in ketosis and burn belly fat then this is needed. But the meals you eat need to make you feel full to have a sense of non starvation. Instead if you feel hungry this is not good and will harm you. So meals need to be crafted to make you get all what you need and in the same time you are doing less calories to bur your belly fat. myth 4: Depends of your age. If your are young probably does not matter, after 35-40 it matters. The Valter Longo study shows it helps to be healthier. Myth 5, again depends. Myth 6 – OK we need fats. And this mean healthy fats not refined oils as pal, soy, seed.. but omega 3 like olive EV, avocado, salmon, butter… Myth 7: not cut, reduce carbs and eliminate simple carbs. And related to bread a white flour one is still a refined sugar. Better a whole grain bread. Myth 8, depends… Myth 9: all sodas are empty calories.. better water this is true. Myth 10: oversimplified.. but generally what said is ok.. still is better to eat with fiber than in a juice form. Myth 11: misleading. As said Valter Longo diet is a 20+ years of study so check yourself. It works. Myth 12: oversimplifying. Keto diet can be interpreted in different ways and some are interpreting it wrong. So is not just fat and protein. If combined with Intermittent fasting and well done with healthy food is the right way. Also no one is saying no carbs. It’s low on carbs. Starchy veggies are pretty ok in moderate doses. Myth 13: it’s true that you cannot change your biology but your microbiome that are the gut bacteria can be changed and studies in labs showed that they play a lot on your health. Myth 14: depends what you mean on the word diet. Diet in Latin means your food that you are eating. So if you are tailoring your menu that is nutrient, qualitative and when you eat you eat till you are having sense of full and in between meals you stop snack then this is sustainable. Of course the industry wants you to snack and this is the issue. Myth 15, is snacks that unbalance the insulin levels. Usually snack are carby and make you hungrier than you need. So it is sort of industry of snacks that is cheating on you. Myth 16: Fatty liver and alcohol does not function together.. so the general condition of the person is to be evaluated when saying yes you can drink. Myth 17: OK true, you can have skinny ones having issues but saying that someone with excess fat is OK and depends on the metabolism is not true. Myth 18: oversimplification. It takes will power and a good dietologist or someone that guides you.. because the industry is more smart and wants you to buy junk food.. And it will also label it very healthy if you cannot understand you will still eat junk with a healthy label.

    i waste 16 minutes watching this



  28. Boomkruncher325 Zzshred on August 8, 2021 at 10:20 pm

    Honestly, I want to do a Veggie/Fruit Fiber Cleanse! Essentially, just eating veggies and fruits for a few days to let that fiber cleanse the body!



  29. Blinkxr _ on August 8, 2021 at 10:21 pm

    u say skipping meals isnt a good idea, althoug in order to lose weight it would be best if u went for a diet that has less calories than what your body is supposed to take right, so it’s possible if u eat two meals and leave one and make it easier for yourself. for exapmle what im doing here is i dont have dinner and i exercise and its working for me. but i guess not everyone’s body functions the same way



  30. RafukaMillan on August 8, 2021 at 10:22 pm

    Pro tip on how to avoid junk food cravings: pour yourself a huge glass of water, drink it in one go and then wash your teeth. The water would make me feel full and the minty flavor of toothpaste would cancel out my desire for any other food. Works for me.

    Also, try swimming. It’s an amazing workout, easy to do and refreashing. Do it at least 3 times a week for one hour. In 6 months I lost 38 pounds.

    Also cut soda out of your life. Best decision I’ve ever made



  31. Ajmal Ahmed on August 8, 2021 at 10:22 pm

    The second nutritionist has the voice of selena gomez.



  32. Mark Lowe on August 8, 2021 at 10:23 pm

    Carbs under 20 grams aren’t the enemy…carbs above that are the enemy. Dieticians are a joke. Keto has proven them wrong and wins the day everyday. listening to dieticians is like going to the team whose lost every game for every season for decades and getting advice on how to win games… I know, I’m a nurse who used my knowledge of physiology to examine the keto diet… I also know because I was close to 500lbs and lost 300lbs in just over a year and have kept it off and reversed my T2 diabetes. Did I mention that my ldl is beyond perfect. I was told I wouldn’t live 5yrs….now I’m my doctor’s healthiest patient and he’s now got himself and family following keto.
    That said I didn’t waste my time watching a sad losing team try to sell loser approaches to remain relevant.



  33. Vishal Rane on August 8, 2021 at 10:24 pm

    They really touched on many myths



  34. Zqnz 13 on August 8, 2021 at 10:24 pm

    I literally can eat 3 times or 2 times



  35. Ethan Tillman on August 8, 2021 at 10:27 pm

    bannanas can make you sleep faster thanks I dont know teacher Edit: I also dont eat much like 2 or even 1 real meals



  36. reasonf97 on August 8, 2021 at 10:29 pm

    So glad this video was made to eliminate a lot of misconceptions about diet and health!



  37. sasha on August 8, 2021 at 10:31 pm

    this was so interesting😄



  38. Isaías Rodriguez on August 8, 2021 at 10:33 pm

    Who knew eating can be so complicated!



  39. karmagomedov on August 8, 2021 at 10:33 pm

    What we need is a debate between well researched dieticians . These ppl are typical diet school doctors whose schools are funded by big food companies like Coca Cola and Kellogg’s and they are talking cherry picked observational research for the companies interest. But it’s not their fault . They have been taught that way. Talking things like IF and keto doesn’t work in the middle of a global obesity epidemic is a joke. There are literally hundreds of actual researches that say we don’t need carbs for our body and IF definitely works. If you want to have a better life avoid carbs , grains and vegetable seed oils. Carbs are definitely your enemies. This thumbnail is a joke. Didn’t expect this from a reputed publication like Insider



  40. Darin Herrick on August 8, 2021 at 10:33 pm

    I disagree on fat. I went from eating fatty meat and fried foods to vegetarian and lost 37 pounds in three months.

    Yeah, you need fat to absorb vitamins. But there’s a little fat in vegetables too. You don’t need to eat massive amounts of animal fat every day. Cut out the animal fat and watch your weight drop like a rock.



  41. Zarrys Lux on August 8, 2021 at 10:34 pm

    this comment section is way too funny



  42. Phillip Lane on August 8, 2021 at 10:34 pm

    @ 3:59 , that poor burnt egg T_T



  43. Kaushik Sarkar on August 8, 2021 at 10:34 pm

    olive is not good for all type of food , In my country the all in one oil is Mustard oil and it is really the best specially cold pressed



  44. james corbeil on August 8, 2021 at 10:35 pm

    I think we should be engaging in straight up propaganda to shift the way people think about this issue, from "weight" to body fat percentage, and from losing or minimizing to optimizing. There are *many* people who need to increase their body fat percentage. Many of these folks have an appearance that is fetishized, but they are in just as much danger as people who’s body fat percentage is too high. There is an optimal balance, dictated by many factors, for each individual.

    I think the reason there is a never ending slew of myths to dispel, is because the very paradigm of thought is so disconnected from reality. People have been convinced to think that there are specific things they need to maximize or minimize, that there are numbers they need to get as high as possible, or as low as possible.

    I think our healthcare communicators would find more success with a focus on how people came to operate under this paradigm and then using those same mechanisms to lead the masses to more accurate ways of thinking about their health and appearance.



  45. munchems on August 8, 2021 at 10:36 pm

    The information given about diet soda is actually very outdated and controversial.



  46. TheMightyOdin on August 8, 2021 at 10:36 pm

    I’ve lost 173 pounds without restrictions to macros or eating windows.



  47. Yesuu Baatar on August 8, 2021 at 10:37 pm

    Music is too loud, difficult to hear what they are saying.



  48. Alex Barker on August 8, 2021 at 10:38 pm

    Reward Day = cheat day for me. The olive oil tip was really good though



  49. Shemiah Walker on August 8, 2021 at 10:38 pm

    What if your allergic to bananas??



  50. saisaivipa on August 8, 2021 at 10:39 pm

    Instead of bringing 3 dietitians with the same point to views, they should bring people with different schools of thoughts together to discuss.
