After hearing your feedback on our initial video, we consulted experts, revised the script, and added more information to the parts that were too simplified. All changes and the link to the original video (now unlisted) can be found here: sites.google.com/view/sources-workoutparadox This experience was uncomfortable, but ultimately encouraging for us. It reminded us that it is a challenge to make ten-minute videos on complex topics without cutting too much and that we need to be constantly aware of this. Thanks again for your honest feedback and for helping us get better. We truly appreciate it.

Here's what's changed, in case you were wondering: ( ) added or changed content ** ** removed content 01:26 In reality, (focusing on) exercising (is not a reliable way to lose weight.) **a bad way to burn fat.** 01:31 (Some studies show that exercise can lead to some fat loss, others that it is minimal. How can this be? It turns out that until) recently we fundamentally misunderstood what moving around a lot does to our bodies. 01:44 (Disclaimer: The science on fat loss is complicated and many studies compare vastly different populations, different measurements and are complicated to understand. And the online discussion is full of personal anecdotes. This video covers general principles, based on the current state of research. But when you look at the individual, there are variations - it matters if you are an athlete or casually try to lose weight.) 03:12 For some strange reason (in the long term), the amount of calories you burn is **pretty much** (often relatively) unrelated to your lifestyle. Per kilo of **body** (muscle) weight, your body has a (relatively) fixed calorie budget it wants to burn per day. 04:12 You actually do burn more calories and lose fat - so you can lose **a few kilos or pounds** (weight) through exercise! But this is (often) very short-lived. Your body adapts and burns fewer and fewer extra calories each **day** (week) until it restores its original calorie budget. After a few months you burn *basically the same* (a very similar) amount to what you did when you didn’t work out. (If you stay really consistent your burn might increase slightly and your body composition might change, but most people struggle with keeping up the habit, if they don’t love the extra movement. Which is why so many people hit a weight loss plateau.) 04:47 (Objection! What about muscles? Muscles burn 3 times more calories at rest than fat. This sounds impressive, but tissues like your brain, skin or intestines burn way more. In absolute terms, a more muscular body composition makes a difference for how many calories your body burns, but it’s relatively small. Muscles matter a lot for health, longevity and performance, but not that much for weight loss.) 05:21 So your body has an **hardwired** activity budget per day that it wants to stick to. 07:13 This is why you burn **almost the same** (a similar) amount of calories whether you work out or not - **by working out you are not doing anything extra, you are doing what your body is literally made to do.** (A lot of the energy you spend working out is energy you don’t spend on other physical activities and body processes.) 07:46 **Movement is not really made to burn your fat though.** 10:00 If you want to lose fat, (reducing calories is the biggest part of the answer.) Edit: I don't like editing comments, but the asterisks were emboldening the words, lol. I've just fixed it! 🫡

So far, the main principles I've taken away from it and which allowed me to shed weight like I've never seen before are: "hunger is not an emergency" and "eat slowly, sitting down, and noticing every bite".

[@theleek6694]

As someone with a research background in nutrition and obesity-related diseases, I feel confident in stating that weight loss studies, beyond sampling issues, are often flawed in their design and include conclusions that are often full of extrapolations. Despite these limitations, one thing is clear from the literature, and that is most people cannot out exercise a "bad" diet, which is to say that the duration and/or intensity of exercise needed to compensate for overnutrition is not realistically achievable. In the video, 2 points that concerned me the most were related to (1) energy needs for CNS vs skeletal muscle and (2) connecting inflammation from exercise to degenerative diseases. For the former, although the energy demands of the brain represent a considerable part of RMR, it remains relatively constant. In contrast, skeletal muscle, which also contributes considerably to RMR, can be modified (ie, increased or decreased), which has important considerations for RMR and regulation of body weight composition. Thus, maintenance or enhancement of skeletal muscle is an important modifiable factor (via exercise or lack thereof). As far as inflammation's role in degenerative disease, it is important to note that acute exercise-induced inflammation is important to skeletal muscle hypertrophy. In addition, although chronic inflammation caused through exercise injury is detrimental, the literature is ambiguous on its relationship to degenerative diseases, such as atherosclerosis. Despite my diatribe, there is a lot of solid points made in the video. Although I might not agree personally with everything, its premise-that our perception of exercise as a solution for weight loss needs to change-is solid. It's a useful tool, but one often mischaracterized.

[@rjones3955]

I appreciated this comment. It was easier for me to understand after googling to understand the acronyms: CNS - central nervous system RMR - resting metabolic rate

[@justmeagain7]

Calorie restriction is the key to losing weight. The easiest way I've improved my diet is by keeping a food diary. I take pictures of everything I eat, and reviewing them showed me why I wasn’t losing weight. It keeps me accountable and motivates me to choose healthier options. My husband, who's great with computers, even created an ap that automatically tracks calories and macronutrients from the pictures of my meals. It's really impressive. After using it regularly, we each lost around 10 kg (22 lbs). If you want to try it, the name of the Ap is: Bitebyte. I hope it helps you as much as it helped us!

[@TheSupermUniverse100]

As someone who's lost 60lbs in the span of 18 months I agree that diet is between 50% and 70% of the journey. I'll share my advice for anyone who's curious: 1. Do not take on big diet plans/ diet pills/ fad diets. Start small and build habits over time. Taking on big changes in a small amount of time is very hard and it becomes easy to relapse. One good example is to try to eat at the same time every day. Your body loves clockwork. Diet pills do work, but they teach you nothing about how to maintain yourself after you're off the pills. The journey of natural weight loss teaches you how to control your weight with your own abilities. Many times, people on diet pills end up regaining the weight they lost because they don't know how to maintain it. 2. Do not make huge lofty goals. Make reasonable goals and put numbers to them. It's easier to track progress by seeing if you're reaching the numbers that you want. A good example is "I want to lose 2lbs evey 2 weeks" or something similar. You can then tie this to a bigger long term goal like "I want to lose 40lbs by the end of the year". 3. This will take time. I remember at first I was getting frustrated by my lack of progress. But then I saw a post somewhere that said something like "you must put as much time into the solution that was put into the problem". In other words, if you were over weight for 3 years, then you should expect your journey to be on the order of years. In my experience, it will take 3 months of consistent work to notice physical changes in the mirror. 4. Excercise goes hand in hand with this. Again, start small. Start with 10 minutes per day of walking/running/excercise/stretching/yoga..etc. You will slowly build a regiment before you know it. 5. Do not fall for the "new years resolution" trap. Do not wait for a new year, a new month, a new week. Don't even wait for tomorrow. The biggest power you have is that you can start right now. The best time to plant a tree was 50 years ago. The second best time is now.

[@MC-wh3xm]

This is EXACTLY what I tell people. Small, consistent steps, that you slowly ramp up as you can handle it. This is great advice.

[@grapfen587]

This is very interesting, since for me it was a lot different. When I decided I was going to lose weight, I went on a diet and started doing small hikes. Did that half a year with pretty much no results. Then I actually scrapped the diet, just simply ate when I was hungry until I wasn't anymore, but went heavy on exercise. 20km of inline skating daily followed by 2 hours of either badminton or fencing in the evening. Started seeing very significant results after 2 weeks and lost 80lbs in 6 months. Also, from my perspective, the only goal you should set for yourself should be to be a normal healthy weight or to reach some sort of fitness level that you want to be at. If you get frustrated because you lost 4 pounds less this week compared to last week, you have the wrong approach, you are worrying about the wrong things, and quitting weight loss because your numbers aren't as good as before is unjustifiably delusional. The speed at which you lose weight will automatically decrease significantly the less you weigh, because a lighter body passively burns less calories. You will also spend less calories to move the lighter body the same distance as the heavier one. That's why I am saying to not look at numbers. Keep doing the things you KNOW work, and do it until you are satisfied. There is no reason to check your weight on the scale until you start to closely approach the target weight you set for yourself, at which point your appearance will already have changed, so you know you are probably close to it. What the scale says is irrelevant, you want to change how your body looks or how fit you are, not the number on the scale if you really think about it. It should be noted that when I talk about eating until I'm full, I mean regular food, not sweets or snacks and not mcdonalds. Basically, sandwiches for breakfast and dinner and some warm meal for lunch, often something with pasta.

[@mrrodriguezHLP]

My 45lbs loss from 2021 to today, is mostly due to my adoption of cycling as a hobby and obsession. When it comes to changing diet, I cut out most artificially sweetened beverages and food, and I lowered my alcohol consumption.

[@sevro]

While I agree with you in principal this is not entirely true for everyone. I personally have been overweight for 10+ years of my life (Obese) and through just a calorie deficit alone (1000 a day only), I will hit a healthy weight within 6-7months. Consistently losing over 1kg a week for the last 7-8 weeks. Just by eating less. And I've personally not found it that hard to not snack or eat so much. A majority of this is because I've been ordering from a meal prep company that give me a perfectly portioned meal that is freshly made that week, its not processed or full of preservatives and I just bung it in the microwave for 3minutes and eat. Each meal is between 400-500 calories and it's perfect. I have one of these a day, have some light snacks throughout the day if needed and then finish up with a bowl of soup if I need to (but I can skip this entirely and finish under the 1K but I usually force myself to maintain the 1K just for health reasons). I am however looking to start the gym up to compliment this and hope to burn even more weight per week doing this, just waiting to hear back from a referral from my GP (Doctor) so I can get a PT assigned at a much discounted rate.

Still there are so many flaws: 1) On the study regarding the Hadza tribe, the 3rd group that is tested, Bolivan farmers, casually is ignored in the video. Because for the Bolivan farmers more movement does result in higher energy expeditor! 2) Bringing up the study that shows people from developing countries do not burn more calories than people from industrial countries. Yes, the study shows that. But it also shows that they dont have a higher "physical activity level"! So it does not support the claim of: They are more active and burn the same amount. 3) The study regarding "Constrained Total Energy Expenditure and Metabolic Adaptation to Physical Activity in Adult Humans" does show that the overall energy expenditor does not increase in an addtive way. But my problem with that study is that it completely ignores the calorie intake of the persons. If they kept it the same for all the test subjects, then this is an expected result. When you are active, e.g. doing sports, you need to also fuel your body properly. If you dont do that for a long period of time (in the study it was 4 weeks when the effects were seen!), then your metabolism will be changed in a way that you dont burn so much anymore cause your body goes into energy saving mode. This is a well known and researched effect. 4) and so on...

One thing important is that people should not focus on losing weight, but losing fat. When you exercise you build muscles which are heavier than fat, so people do not notice the change on their scale and give up. Another thing important is what people eat, a balanced diet with few processed food helps the body a lot.

[@the_seeker.entity9206]

You can lose a lb of fat per week pretty easily. No one is gaining a lb of muscle in a week. That's just not how it balances out. You're not in enough of a caloric deficit if you're not seeing weight loss.

I think the effect of building muscle and increasing your base metabolic rate by 200-300 calories is vastly understated here. You only need a 200 to 300 calorie deficit to lose weight in a healthy and sustainable manner. That's just 1kg of fat in 30 to 40 days.

[@MewPurPur]

While that's fair, realistically, it's more like 30 calories per day, say, you replace 5 kilos of fat with 5 kilos of new muscle.

[@PeterMoore-q5k]

It's a 4-7kcal/lb difference but that's also assuming "replacement". Just adding the muscle lbs without losing the fat increases base burn by 6-10. And then consider that if you're stronger you're naturally going to move faster, etc. It's all a feedback loop. It's not Ozempic-speed weight loss. But it's about changing body composition over months and years which is the only sustainable way to do it.

[@Paraselene_Tao]

I work out specfically to grow muscle, and this video doesn't touch much or at all on that topic. I'm solidly happy with my body fat percentage. I'm working on becoming stronger, more lean, and more functional. I resistance train about 3x/week with progressive overload on compounds in the 5 rep range. I'm following a free online program called Stronglifts 5x5. I've done this for a year, and I've seen big changes. I recommend it for everyone because we should all be putting some effort into becoming stronger. My form of resistance training isn't the only way, but it's a very good way to build muscle. For me, because I'm not worried about body fat, my diet is focused on high protein. The calories simply follow my protein, and I don't worry about calories. That approach may not work for everyone because folks have different goals or prioritize certain goals over others. Maybe one day, I'll work on getting my body fat percentage to 15% or so, but for now, I'm happy at about 22%.

We're caught between fitness influencers selling workouts, food companies pushing processed junk, and pharma companies profiting from both obesity and weight loss drugs.

i don't think the main criticism of this video disagrees that diet is important for weight loss and probably more effective for total weight loss than exercise, i think the crux of the problem is the video seems to go out of its way to say that exercise is virtually pointless in the endeavor to lose body fat which is almost comically inaccurate. Anyone who trains for a cardio event can tell you that an uptick in exercise intensity or frequency can drastically effect what they have to eat to avoid losing too much weight/muscle. Why is that? It's because they are burning more calories through exercise. This video is annoyingly detrimental to this idea and the "retraction" is almost more of an insult to that very idea because of the fact it just doubles down on what they said last time lol.

[@Destrifik]

Its kind of disingenuous to attribute purely "weight" as a metric for health when muscle weighs more than fat. If youre actively losing weight, and then gaining muscle due to working out, you can expect the delta of fat weight loss vs muscle weight gain to get smaller and smaller

[@micahandjessi]

True, but the rate of gain for muscle vs the rate of loss for fat is vastly different.

If you're covering both exercise and nutrition as components of weight loss you need to cover the third thing which is actually the most important of all: sleep.

[@Rich50v]

I've gone from 24.10 stone to 17.13 stone in exactly 5 months to the day. My diet is around 1100 - 1500 calories a day and is fairly well balanced (good amounts of fruit and veg). I only do two things for exercise: I walk anywhere between 8-12 miles a day (sometimes more sometimes less) I do push ups (i'm still too heavy/weak for more than a handful of horizontal ones so they are mainly against surfaces) An older family member is doing the exact same diet as me but not the walking or push ups and has lost 1.3 stone. So in my opinion, exercise is 100% vital to (fast) weight loss. I am not bragging, just stating my observations, make of it what you will.

[@197228sept]

I don’t want to take away any of your achievement - you are working hard and have truly dropped a lot of weight - but I don’t see how this comparison with your older family member is relevant… Is your family member also in the same weight range? Were you on the same diet before you switched to the new one with less calories? Do they take meds? Yes, some meds do cause the body to retain water, for example, or to build more fat! Let’s face it, you were obese before you changed your diet and started working out. Now you are probably around the weight you should be (it is based on your height and age too, after all). You lost that weight because it was sustained by your lifestyle. As the video states, calorie depravation and introduction of movement do help but over time, you will slow down on the weight loss. Nevertheless, proud of you! It is not an easy change but I am glad you have stuck to it! ❤

Key point summarized: Exercise is healthy because it removes energy from processes that harm your body and uses it for movement instead.

In other words: Our bodies naturally expect lots of movement, so they produce a lot of hormones related to that; and if we don't exercise, the excess hormones end up hurting us instead.

That's not the key point at all. The key point is that the current obesity epidemic is caused by over eating and not by under exercising. And over eating is mostly caused by the rapid change in the ease of obtaining large amounts of calories.

Really good on you to update the video - I tried sharing this with a few friends who all disregarded it as "bull" because the current understanding of weight loss is all just "work out more" and calling it a "paradox" doesn't drive interest in people that dont want to hear that science changes

[@tom-lord]

Your friends were right. The video is nonsense.

This updated version is a significantly better overview of the topic. I still think the fact that your body sacrifices other bodily functions (even important/necessary ones) to allow movement that may get you food a little understated. The movement/starvation cycle is very very real in the natural world and breaking that cycle with agriculture is why humans have come to dominate basically every geography and ecosystem on the planet. I also think it was a huge improvement to include relative energy consumption for higher intensity activities like cycling. 600 kcal is pretty easy to compensate for with your diet, but it' also represents a huge percentage of the daily energy budget for most people, which means it's nothing to sniff at in the long term if done on a regular basis.

[@ITS-HALBY]

A misconception kind of related is the fact that many people associate body building with fitness. I wanted to compete, so I was pushing myself extremely hard until a Mr. Olympia medalist I talked to at my gym told me "bodybuilding isn't about staying alive longer, it's about winning more, it's not healthy, it's not fit" so a lot of people are just trying to take themselves from one extreme to the next when longevity and sustainably are the more viable strategies.

[@LLS.R]

If you don’t stuff it in your mouth than you don’t have to train to lose it.

[@RyuLightorb]

​@@LLS.R good advice yes my issue was that i was completely sedentary i rarely left my bed for a few years i was eating at my BMR which was 1704 calories a day. Plus i also have a thyroid condition which doesn't impact my metabolism that much it just means that i need to eat slightly less than the average person by like 100-200 calories more to lose weight. To lose weight i would have had to eat less than 1700 calories a day. Which is do-able but it's not ideal for nutrition i would have had to cut out a few serves of veg or my oats. Which is why when i saw a dietician they didn't change my diet after checking it out and instead got me to start moving instead of being stuck in bed all day. once i started moving exercising by adding 4000 steps minimum daily i started to lose weight. No exercise is bad, being completely bed bound is EXTRA bad. Once i started getting out of bed and moving through the day i dropped weight...then i added in exercise lifting weights and i lost even more. The only time i had lost weight prior to seeing a dietician was when i cut out fruit and veg and other stuff that was essential to my diet and was eating around 1300 calories a day, i had to stop that however because i kept getting sick. These days i'm going well i'm glad i'm not at that point of my life anymore.

Ouff, I'm not so sure this video was a good idea in general. The updates that clarify some points are appreciated but some do seem to contradict the point this video is trying to make now. Thinking specifically about these two sentences here: "Per kilo of [-body-] *muscle* weight, your body has a relatively fixed calorie budget it wants to burn per day." "If you stay really consistent your burn might increase slightly and your body composition might change, but most people struggle with keeping up the habit, if they don’t love the extra movement. Which is why so many people hit a weight loss plateau." That says to me the problem isn't actually that the calorie burn is leveling out, it's that people are not properly keeping up with their habits after a while. I also think releasing part 1 that basically says "Don't use exercise to lose weight, consume fewer calories" without releasing part 2 that focuses on proper nutrition, promotes dangerous dieting practices. I wish this hadn't been released on its own without offering the proper advice that is hopefully coming eventually in part 2!

[@danielborrus]

That was really well said. The revisions they made kind of back-peddle on their prior conclusions. Ultimately, I think the evidence for the constrained energy model is still a little shaky and it's far from nailed down. Claiming it as fact, like this video and its predecessor did, is just dishonest presentation of scientific data.

I watched the previous version and was kinda stumped by some of the statements, making me love this one a lot. Throughout clear explanations and perfect simplification of controversial and complicated subjects paired with your lovely animation style made this a joy to watch. Thanks a lot.

[@GENYRED]

Here is my comment from the previous video, the "Updated Version" is just a more vague version of the previous video with *some* needed changes... : I'm sorry but this video is worded horribly, good amount of people will misunderstand it, the loss of calorie loss over time in training happens because people don't progressively make their work out harder, you will always burn more calories while training, and yes no amount of training fixes a bad diet, but it is surely the one of two components of weigh loss, every person should do sports or train in some way to be healthy, please don't misunderstand the video thinking you don't need to exercise to be healthy or fit.

[@whisperSSG8]

I think it could still be worded better but this is miles better than the original. That one was straight misinformation

[@-Raylight]

This brings the *"You're your own worst enemy"* to the new level. Imagine exercising hard and eating less only for your body to sabotage yourself Good intention but they should tell us first, wish we could say communication is important to our body xD

[@MisterCynic18]

Well you sabotaged it first by creating a civilization where it was physically possible to find and eat 10,000 calories worth of food on a daily basis lol

[@potatoppppower]

​@@MisterCynic18 As well as the creeping corruption of the food industry by profit motives! The media often report on food science with oversimplifications and sometimes deliberate misrepresentations of scientific research. That in turn makes nutritional science confusing and inscrutable for most people.

[@Jcewazhere]

Don't have to imagine it, I'm living it lol Lost 20lbs in 2 months, then the following almost 3 months now I've gained and lost the same 10lbs over and over. Plateaus suck. I'm still down ~25lbs consistently which is nice, but I want another 50 gone.

[@86zerueldososo64]

>Imagine exercising hard and eating less only for your body to sabotage yourself Imagine believing this actually happens. This video and the whole fat-positive propaganda machine really did a number on you morons.

[@MrAlternateTheory]

@@Jcewazhere What about composition? Would you say you are leaner at the same given weight, or no difference in that department? I don't think that 10lbs is entirely the plateau you may see (though it is a prompt to adjust/refocus); Lets say over 5mths you are down 25lbs from where you started (which is actually really good). But now consider you are possibly down 35 - 40lbs from where you would have otherwise finished! I.e. Don't just compare to where you started the journey, but also to where you would otherwise have finished the journey (like I said, I'm envious, 25lb is great... best of luck with your goals)

[@RallyXsings05]

I don’t remember what I said in the old video but this is much better! Also it’s nice to see a different perspective on exercise, especially when it comes to seeing it beyond weight loss. And hey, even if someone isn’t after weight loss, it does in fact help them with other sorts of other things too like mental health! 👍
