      He doesn't reject keto, but makes a solid point - if you combine it with intermittent fasting and only do 2 meals a day, then you will not grow. If the meals are overly rich in protein 50+ , then you are turning good protein into fat.

        perhaps, but I don't care about fat as I'm not fat. I only care about the longevity aspect. and personally I find IF to be extremely difficult. you have to go through a metabolic switch every single day (from glycosis to ketosis). I find that 12-16 hours are the hardest following my last meal. but I seriously doubt OMAD works well for longevity as you barely enter autophagy. you would need alternate day fasting or even longer periods to really tap into cell renewal. on the other hand in keto you are basically constantly in ketosis, there's no metabolic switch, hGH is constantly high, IGF-1 is constantly low, it's not periodic like in IF

              I'm mostly mocking people who fast and pretend they can build muscle in case you fail to grasp it. The unholy combo of keto + fasting is a terrible meme for anyone looking to build muscle.

              Yes. A true dork, but he gets decent guests on.

              DEXA scans can be unreliable because they cannot discern water. IF may reduce sodium intake and thus water retention which can produce a false reading on a DEXA scan where you probably lost water vs losing muscle mass, there's also timeframe as well, I didn't watch the video so if it was after a few months of IF and they lost the muscle mass, there might be something there, but if you use IF acutely to lose some weight, you probably won't see a decrease in muscle mass.

              Furthermore with the protein thing, your body will use the protein you give it, it just won't use it for muscle protein synthesis over a certain amount per meal, which is why you want to space your protein out as much as you can, but protein intake is not as important as a lot of people that sell protein supplements will tell you. Resistance exercise leads to the greatest stimulus to build muscle. You don't need to maximize your protein timing / intake unless you're competing. As long as you're not eating all your protein in one meal, you're likely reaping a lot of benefit from it if you are consuming at least 100-150g a day over at least 2 meals preferably more.

              Really this stuff is getting into the nuances of these topics and isn't really useful information for the average person that wants to get fit and look better. These things are like 5-10% of the issue. Consistent exercise and consistent sleep with consistent eating prioritizing protein is what is going to produce the vast majority of results for people.

              >Really this stuff is getting into the nuances of these topics and isn't really useful information for the average person that wants to get fit and look better.
              Yes but the topic is about intermittent fasting, which is a niche within the fitness world, despite being relatively popular lately.
              >You don't need to maximize your protein timing / intake unless you're competing
              Yes for the average person. But here we are talking about a fasting person, who has a 4-8 hours max time window to get his daily food. The rest of the time he is fasting.
              The meal situation becomes very complex then, and these are at least 3 big meals at nighttime, which will affect sleep.

                If intermittent fasting is how you can lose weight, then you should do it, get to your target weight as fast as possible, then maintain.

                IF is not going to cause muscle loss acutely, only if you do it chronically. If you are eating your protein target over 2 meals, you are likely reaping most of the benefit of protein. You are not minmaxing protein, but you are getting a benefit from it.

                The real question is just timeframe. The longer you spend in an unfed state, the more catabolic you will become and your body will adapt to that. There's also bodyfat to consider. If you are over, say 18% bodyfat, none of this really matters to you, only when you get into the low teens of bodyfat is where you really have to pay attention to maxing out everything to keep your muscles growing or rather not losing while on a deficit.

                There's a lot of nuance to this and this just isn't able to be parsed in an interview like this.

      Go ahead, eat a 150 g protein meal in a single sitting. You'd be turning great protein into fat and not building any muscle.
      It's fricking moronic. All the bodybuilders know meal times and meal size is important, yet some numbskull comes along to argue otherwise.

          This is broscience myth that I keep hearing everywhere, but actual studies shown that this isn't true.
          Total daily protein intake is only important metric. If it's in 2 meals, 3 meals, or 6 meals is irrelevant.

              What is needed for survival vs what is optimal for maximum growth are two different things. Your body will certainly use the protein, it's not going to waste it, but muscles are very low priority in terms of protein partitioning. Your muscles can only grow at about .5 - 2 lbs a month. That's about 900 grams total of protein a month that's partitioned towards muscle growth, so what 4-9 days depending on your intake, the other 20-24 days of the month your body is using protein for other purposes.

            For muscle growth it’s best to space protein across 3 or more meals.

            For fat loss it’s best to fast or — low carbohydrates high protein, high water

            Protein intake above 0.7g/pound is not proven to be athletically beneficial. So a 150 lb man should get around 105 grams of protein to optimize, and a 200lb man should get 140g of protein to optimize.

          how many meals, over what period of time ?

          >How will you fit 160 in 2 meals without turning a lot of it into fat?

          By eating at a caloric deficit. 220 lbs is very heavy for a guy, so you are likely either roiding or very fat to begin with and I'd argue that you should prioritize weight loss before you do anything with protein intake.

          There really is no reason to be 220 unless you're competing in some way, you're just inviting health problems at that weight and if you're not getting paid to be at that weight, there's no reason to be at that weight.

      Tbf Attia has basically given up on everything but exercise. He has stated that he has dropped keto, fasting, metformin and statins for himself over the past few years- if he ever actually did them, of course.

      Big on a exhaustive battery of tests for those who pay $160K a year for his concierge medical service tho. He still likes throwing those people on various drugs (mostly TRT, no wonder they feel so good...) with the rest mostly being an incredibly pedantic and prescriptive exercise protocol.

      He knows his audience and customers very well, panders to their neuroses, and has done an impressive job of hitching a ride on various bandwagons then jumping off in time.

    All those studies about needing to space your protein were done on rested individuals

    If your body has heightened MPS from exercise, you can use way more protein in one meal.

    This is why some studies show 40g max, some show 70g...
    If your exercise you can use probably 100g+

      I'm also amazed that the 40-50g prescription apparently applies to 100lb women as much as 240lb men.

      he's had protein researchers on his show, and that's about what they say for muscle protein synthesis, you also need at least 3g of leucine per meal to really stimulate it.

      There's a difference between stimulating MPS and using protein for other bodily functions. This is what he means. You can consume as much protein per meal as your body wants, it will actually slow digestion to use it all up, but there's a max amount that it's going to use for MPS. People are just misinterpreting what exactly he's saying

    Fasting just works. It's not starvation, it's using your body's fat stores. Fasting is the ultimate ketogenic experience.

    Imagine fricking around with diets and restriction and starving yourself when you can *literally* get a script for Wegovy and just drop weight without thinking about it.

        That's basically how GLP1 agonists work. They make you feel bloated and overstuffed when you eat, which makes fatties stop eating. Of course since they're artificially overcoming their fricked up hormonal response, they're not actually training their bodies and minds to stop being spiritually fat. So if they ever stop taking the expensive weekly injections, they'll balloon right back up.

    I've been doing OMAD for years along with occasional prolonged fasts for a few days at a time as a form of "mini-cutting" when I want to lose a couple pounds. I've never been stronger or felt better in my life than I do now, and I can do 2/3/4/5. It just werks(TM) for me.

    >40-50 grams of protein per meal, anything in excess becomes worked into something else
    then only eat 40-50g in a meal and have 2 meals and a high protein snack, totally doable in an 8 hour eating window
    >you literally get fat on it
    you literally burn fat if you aren't a lazy gay and prompt some ampk (regardless of whether or not ur in keto or glucoblabla at the given time of training)
    >intermittent fasting on 2 meals a day is guaranteed muscle loss
    2 50g protein meals and high protein snacks can more than help you retain muscle and eating high protein over the span of 8 hours is anabolic as frick
    >the only way for intermittent fasting to work is 3+ meals after the fast and they have to be high protein
    they have to be high in cholesterol to precursor testosterone, the retention of lean mass is largely based on your hormonal makeup (good thing keto is largely animal fat and yolk)
    >autophagy that prevents cancer may or may not trigger at 20 hours of fasting
    again ampk can be triggered easily as frick to speed up anti cancer properties and also deplete glycogen to accelerate the onset of said properties
    >intermittent fasting benefits are put into question
    literally what question op? is the question why you watch these morons? or how about why so many morons are replying to this thread with their dogshit takes?

      for reference i swamp like 200k+ lbs a week of frozen meat in a fricking frozen warehouse for work, energy demands are no question for me and mixing IF with keto has given sufficient animal fat and protein to recover from work, and sufficient nutrients to have the energy to perform said work. in about a year of on and offing with it, i've recomped from 236 high bf% to 180 statue status by just eating high protein frequently in my window and getting enough sleep, don't let people shake your faith in IF brother
