IF does work well for me, but I have always understood it is a tool that works better for me because of my psychology. I have always found it easier to not eat at all versus trying to eat just a little and then stop. I also have a huge appetite and with "normal" size meals rarely feel satiated. With IF I can eat larger meals, feel more satiated, but still eat less over the day.

@albundy3929 Your body is meant to feast and famine. Your body can handle any amount of protein any time. Have you ever heard of competitive eating? The RDA of protein is 50 grams per day that's it. Your body either needs the protein or it doesn't its that simple. Your body only stores carbs and fats it never stores protein. It's almost impossible to not get enough protein a day in any developed country because even plants have protein.

Maybe it also have to do with less stress in the morning routine. I always prepared healthy meals in the morning, so had to reserve half an hour for that incl eating it. Now have an hour free time to go for a walk or something. And that's the most important thing; it makes me feel good and there are too many variables for that to measure.

IMO the main benefits of intermittent fasting are limiting how many times you spike your insulin per day, and tricking yourself into eating less. The 2nd one doesn't work for everyone, but the insulin benefit still remains. I think people are arguing about it in the wrong way. Strictly speaking intermittent fasting does NOT help you lose weight, i.e. if you have the same amount of caloric intake while intermittent fasting vs. not it won't have a different result - it isn't a magic wand. But if a certain schedule of eating can trick you into eating less.. then it sort of does help you lose weight. This is a pretty hard thing to research/prove though since everyone is so different. Some people will end up being hungry less if they break up their day into tiny meals throughout the entire day, some people can wake up and not be hungry until 3 or 4 pm. And everything inbetween.

Very interesting and topical for me. First, because I recently started following IF. Not because I was looking to lose weight or restrict calories. Rather, because I listened to a podcast with a scientist who discussed the research supporting its benefits for brain health and preventing cognitive degeneration as we age. Second, as a coach, I always tell my clients that calories are king when it comes to weight loss and that there’s nothing magical about any particular diet out there. Pick the one that works best for your lifestyle and food preferences.
@guibox32 ай бұрын
Disagree. Why do people burn more fat and others store more fat? Because when you eat and what you eat are as important as how many calories you eat. Why? Because even though calories are important, your hormones determine what your body does with those calories. Some foods trigger different hormones and some people can increase the CO of CICO more hardcore. Your body is a complex thermodynamic system, not some sort of scale that says, 'you must absolutely eat 2100 calories. Any more and you will gain weight. Any less and you will continually lose.' CICO is the gun but hormones pull the trigger. This is why someone eating 2500 calories can be torching fat while others on a strict, 1100 calorie diet are stalling big time. Case in point. I was always gaining weight usually eating between 1600-1800 calories on an average. When I tried keto, I was told to increase my calories to 2200! I ended up losing MORE fat in a FASTER time then when I was eating a high carb diet before. So hormones are very important because you have no idea how many calories your body will really store or burn on a given day.

I like human randomized control trials like this. It shows what Dr. Norton has been saying all along. I follow my own protocol of TRF OMAD twice a week and TRF 16/8 maybe once a week, but I used to do 16/8 every day and OMAD twice a week prior to listening to Dr. Norton. Six years ago, my primary focus was fat loss, and the Keto diet helped with that tremendously. After living overweight for most of my adult life, Keto seemed like the answer- and sure enough it worked. That said, I can also tell you that I was in a caloric deficit and incorporated regular strength training into my weekly routine for the first time. Today, my focus has changed from fat loss to adding muscle, and I do not want to hinder muscle growth. The reason I still do OMAD is because they are the days I get to eat a lot at dinner time and yet still not exceed my basal metabolic rate :). I also have experienced multiple times where fasting helps prevent bloat and/or water retention in the cells, especially around the midsection. I can see more vascularity while on a fast. Of course, it is only temporary and after I eat that effect goes away for the most part.

Good to know that there isn't a significant difference, as I use IF to stick to my planned overall daily cals/macros intake (I find it quite easy to not eat until noon, and stop eating after 7pm), but also 'break' IF on my gym/wt training days (3x/wk) when I do the gym session 9-10pm and then have a protein shake afterwards. But while this study focuses on the impact of IF on wt loss and insulin/glucose, there are also 'supposed' to be benefits from IF around triggering autophagy -- which might help with both 'loose skin' mitigation during/after wt loss, and reducing cell senescence and extending lifespan and/or healthspan. Probably be a long time before we get any decent empirical data on that, as both effects are over the long term, so hard to get a study with compliance and a control group to participate (or be funded) for the length of time that would be required (12 weeks wouldn't tell you anything). ps. the best benefit of IF for me was to make it easy to avoid 'snacking' after dinner or between meals -- my lifelong overweight issue was mostly due to indulging in snacks, dessert, lollies etc. "between meals" -- by three main meals per day were actually quite healthy and wouldn't have led to weight gain by themselves.

Based on my review of numerous videos and studies, I’ve come to understand that intermittent fasting (IF) functions as a versatile tool, with its effectiveness largely determined by the duration of the fast. In my view, the length of the fasting window plays a critical role in shaping the metabolic outcomes. For example, a typical 16:8 fasting schedule-where you fast for 16 hours and eat during an 8-hour window-primarily serves as a caloric deficit tool. After just a few days, fasting leads to a natural suppression of ghrelin, the hunger hormone, which reduces appetite and makes it easier to consume fewer calories. This caloric restriction helps foster weight loss. However, when the fasting window is extended beyond this, and assuming physical activity levels are maintained, intermittent fasting transitions into a more potent fat-burning tool. The longer fast, in this context, enhances fat oxidation and may trigger physiological changes that promote fat loss more effectively than shorter fasting windows. Thus, IF can serve different functions depending on how it is applied and how long the fasting period is sustained.

14-15 hr is underdosing the intervention. Of course it's not going to work when compared to a longer period isocalorically. 15hr won't get your insulin low enough for long enough for you to actually enter ketosis and break down fat, therefore any weight loss benefit you can get from it could only be the result of calorie restriction. And calorie restriction while insulin is moderate to high means lowering your metabolic set point (see e.g. Biggest Loser study that Jason Fung talks about) making weight loss harder to maintain after your leptin and ghrelin snap back like a rubber band.

If I eat low carb, I don't get a spike and it keeps insulin low and I can go 24 hours without eating again that is how I can eat less calories than I used to and not be hungry all day. Hunger always wins so keep that insulin low and become insulin sensitive.

IF (and low carb but not really Keto) is working for me cause I will tend to eat more per day otherwise. At night I would snack, or eat an extra meal or whatever. And IF keeps me focused on eating healthy when I do eat because I have a game plan and goals to stick to. The issue that I had when I did it 5 years ago was that it was really effective and got almost too thin, but after 5 months I didnt stick with it anymore and gained the weight back, so I may need to figure out a new game plan if I can't stick with it.

I really like Dr Layne Norton's takeaway, and it's the same takeaway I would have: IF can potentially be a great tool for weight loss if it happens to work for you, and at the same time, I have become more wary of claims that IF provides unique health benefits not seen in a more simple calorie restriction protocol. I think for the research to be more conclusive, we would need to look at other protocols such as a smaller feeding windows and fasts where a few days a week you fast the whole day. The timing for the feeding window also adds an additional variable, although my feeling is that it's not particularly significant, especially if we would hypothetically expect morning feedings to be better and didn't see that in this study. In general, I would say that this is a mark against the idea that any IF protocol somehow provides unique health benefits (with more research needed for other IF protocols). This absolutely makes me apprehensive about making claims about unique health benefits for larger feeding windows as seen in this study.

I'm a carbon diet coach subscriber, and I'm unsure if there is any way to account for this, but man water retention throws off everything. Here is currently what I'm doing: - 6 days a week to lifting (ppl*2) - walking 8-10k steps per day - Carbon has me on 2200ish calories, which I adhere to. I track all my calories and prep my own food. I am 6 foot 1 and 200 pounds. This week I have gained nearly 4 pounds and I have no idea how. I know Carbon is going to want to lower my calories, but I really don't think that's the issue. I think, because it's summer time and I'm drinking more water, that this is merely water weight. Not sure how to go about weighing myself as I do it early in the morning consistently.

While the effect of TRE vs UEP using an isocaloric diet appears equal in this small study, are there studies that show any differences between using TRE vs UEP when exercise is also utilized as part of the intervention? Like feeding close to exercise (before or after) as it relates to not just weight loss but also to lowering a1c levels in diabetics and prediabetics?

It all makes sense when you look at it from an energy perspective, which is why athletes eat carbs for what they are about to do. Intermittent fasting may be Better if it was centered around exercise needs. Then the spontaneous drop in activity would not be as big a problem.

I believe there are some studies showing people down regulating their neat, while simultaneously reporting increased neat (reporting that they are moving more), while wearing an accelerometer showing that they down regulated their neat by an extremely large amount. But they thought they were moving more because they did a little bit of exercise in the morning, or some such. People start exercise, feel wonderful about themselves tell the world, report to researchers that they’re moving all the time because they have memories of themselves exercising. But their hypothalamus takes over and they move less, extremely unbeknownst to themselves.

It's more about timing the big meal of the day 3 hours before the workout so you are pumping protein carb and nutrient rich blood into your muscles. That's why I do the 16:8. I don't need to ask anyone if it works. Also, walk or do chores during the fast.

I still do IF for the practicality and effectiveness of limiting calories in my day. Fewer opportunities, fewer unsatiated hunger states. It's just a caloric restriction behavioral tool for me which allows me to still eat dinner with my family and young children. It's too bad that a lot of the "magic" hope put into fasting has been deflated but it's STILL the only caloric restriction tool that works for me.

I do IF because eating smaller meals doesn't satisfy me and I end up eating more. But if I eat a large portion in 1 to 1.5 hours between 4 pm to 6 pm. I will be full the entire day. Tried it for 2 years and even tried going back to regular meals for several weeks. I calculate that if i eat 3 meals a day, I actually eat nearly 500 to 1000 calories more than just 1 big meal. So yeah IF is basically calorie restriction for me.... Just an easier one.

One problem is that some people's adherence is to overeating, leading to a high prevalence of obesity. Without effective methods to limit intake or increase physical activity, we leave it up to chance or habit, resulting in poor outcomes. None of these tools are magic bullets. What intermittent fasting does is set parameters, similar to those we have for our workday, study time, and gym time. When we adhere to those, we see results. Oftentimes, when a person doesn't set aside a specific time to complete a task, it doesn't get done. Even using the Carbon Diet Coach requires adherence. If you don't take the time to accurately input the necessary data, your results will likely be poor. This is primarily because you're once again leaving it to chance that you probably hit your macros and consumed the allotted amount of calories.
