00:00:00"What is the maximal anabolic dose of protein per meal for the goal of muscle building?"
00:00:06We boiled it down to first in the order of importance is total daily protein.
00:00:11If you get total daily protein right, the timing of the constituent doses of the total
00:00:16are just a distant secondary concern. It didn't make a difference.
00:00:19If you can give an across-the-board recommendation of how much protein people should consume
00:00:27post-resistance training, let's just leave cardiovascular training separately for the
00:00:31moment, post-resistance training, what would that number be? Would it be 20,
00:00:3530, 50, or 100? Should it scale with body weight? And how long after training should one
00:00:42consume that protein if the goal is muscle protein synthesis?
00:00:46To maximize MPS, we really haven't seen doses beyond 50-ish grams, 30 or so to 50.
00:00:54My colleague Brad Schoenfeld and I, we scoured the literature and we wrote this paper on what is the
00:01:01maximal anabolic dose of protein per meal for the goal of muscle building. And we boiled it down to
00:01:08somewhere between 0.4 to roughly 0.6 grams per kilogram of body weight. And so in freedom units,
00:01:16we're talking 0.2 to 0.25 grams per pound. And that is what appears to max out muscle protein.
00:01:24- 0.2 to 0.5 grams per pound. - 0.2 to 0.25.
00:01:28- 0.25. - Yes.
00:01:29- Okay. - Yeah. So like about a quarter
00:01:31of your body weight in pounds, if you're looking at grams of protein to maximize per muscle protein,
00:01:37yes, per meal. - Okay. Sorry,
00:01:39because I think many people including myself are going to say, okay, but this is only in the meal
00:01:44post-workout. I mean, I wake up in the morning and I try to work out before I eat because I like to
00:01:49do that. Sometimes I'll have a little bit of protein, but let's assume two conditions just
00:01:53for simplicity. Somebody did resistance training in the previous two hours or, and they're trying
00:02:00to evaluate how much protein to eat at that meal in order to maximize muscle protein synthesis,
00:02:05or they're eating a meal separate. On a day, they're not resistance training.
00:02:11And then as just kind of a generic example of a meal that doesn't follow resistance training
00:02:17in a window of two hours or so, how much protein should be consumed at these two different meals?
00:02:22- We did a meta-analysis of the existing literature, looking at the anabolic window thing. And for the
00:02:29listeners, a meta-analysis is a study of the studies. You collect all of the studies on a
00:02:34given question, and then you kind of see, you look at effect sizes and you sort of see where the
00:02:40evidence leans, whether there's a significant or meaningful effect. We collected studies that
00:02:46compared a protein timing condition where protein was timed within an hour, either pre or post
00:02:53exercise. And then the control group of the study would have to have protein a minimum of two hours
00:03:00of nutrient neglect on both sides of the training bout. So we collected all the studies that
00:03:05compared these conditions. Essentially, we found that as long as total daily protein was about 1.66,
00:03:121.7 grams per kilogram of body weight, so about 0.7 grams per pound, as long as total daily protein
00:03:20was at that or more, then the timing relative to the training bout didn't make a difference.
00:03:28- This is important for people to hear because what this translates to in my ears
00:03:33is a very simple takeaway, which is that you don't need to obsess about the
00:03:37post-training anabolic window, especially if you're eating prior to training because you have
00:03:46nutrients circulating. Now, if you eat your last bite of food at 8 p.m. and you wake up at 7 a.m.
00:03:53and you're training at 10 a.m., then perhaps by time you finish your leg workout or whatever
00:03:58resistance training workout you would want to prioritize getting some protein and other nutrients
00:04:03into your system. What you're saying, basically, it's so logical now that I hear it, which is that
00:04:10you have nutrients circulating in your body and stored in your glycogen and so you're pulling from
00:04:14a reservoir. If fasted doesn't necessarily mean starving. - First in the order of importance is
00:04:20total daily protein. So there's this hierarchy of importance. If you get total daily protein right,
00:04:26then the timing of the constituent doses of the total are just a distant secondary concern.
00:04:33- Is there anything wrong with consuming a high or very high protein meal every once in a while,
00:04:40especially if you're not eating much or consuming much protein throughout the day? And the reason I
00:04:46ask this is for practical reasons. Many people find it difficult to distribute their protein evenly
00:04:53through the day. Many people also find it difficult to get enough protein in the middle of the day
00:05:00meals or the morning meals. It can be done, and I know people will say, "Well, you have some eggs
00:05:04and some protein." There are ways to do it, sure. But at least in this country, most people tend to
00:05:09emphasize dinner as their largest meal for better or worse. So a lot of people stack their protein
00:05:14heavily towards the end of the day. Assuming caloric load is appropriate, et cetera, is there
00:05:19anything fundamentally wrong or bad about doing that from the perspective of body composition
00:05:24and health? We're talking about the general population, not somebody who's trying to
00:05:31win a physique competition or run a marathon or ultra. - I would say no. One of my colleagues,
00:05:36Yassine Locke, he took our pre-post model and he kind of like, he ran his own
00:05:46randomized controlled trial version of it, but he wanted to kind of exploit the possibility of
00:05:51further protein neglect on both sides of the training bout. So he compared an immediate
00:05:57pre and post, immediate pre and post 25 grams of protein, sandwiching the resistance training bout
00:06:03with a group that neglected all nutrients for three hours on both sides of the resistance training
00:06:09bout. Total daily protein was optimized at around close to a gram per pound, two-ish grams per
00:06:15kilogram of body weight. No significant difference, no meaningful difference in muscle size and
00:06:21strength gains at the end of the, I believe it was a 10 or 12 week study. - That's very reassuring to
00:06:27me. I mean, because I have a busy schedule as do many people. Sometimes people don't like to eat
00:06:32immediately after they train. Sometimes you have to shower up and head to dinner after you train or
00:06:39shower up and head to a meeting and you don't have the opportunity to ingest in the quote unquote
00:06:46anabolic window. So what I'm hearing through all these answers, correct me if I'm wrong,
00:06:50is that there's tremendous flexibility as to when you consume the protein that we all need,
00:06:56but that the overall protein requirement seems to center somewhere around 0.7 to one gram per
00:07:03pound of body weight, somewhere in there total per day. If the amount in a given meal is a bit higher
00:07:08than 20 or 30 grams, you're fine. If it's a bit lower, you're probably fine. But the thing that
00:07:16also I believe needs highlighting that most people don't talk about is distinguishing between what's
00:07:22in circulation versus when one ingests something. Like we love to think that we drink 30 grams of
00:07:29protein or eat the chicken breast or the piece of steak or have the eggs and suddenly those amino
00:07:33acids are available. And it makes so much more rational sense now that you describe it,
00:07:38that eating first makes those amino acids available for the muscles a couple hours later. And we just
00:07:46don't learn about it that way. So I'm very grateful that you're bringing it up that way. I realize we
00:07:51could probably drill into protein requirements ad nauseum, but think about this way. The way I like
00:07:57to put it is total daily protein is the cake, the specific timing of protein relative to the training
00:08:05belt. That is the icing on the cake and it's a very thin layer of ice.

Key Takeaway

Prioritizing total daily protein intake of 0.7 to 1.0 grams per pound of body weight is the foundation of muscle growth, rendering the specific timing of post-workout shakes a minor detail for most people.

Highlights

Total daily protein intake is the most critical factor for muscle building, outweighing the importance of specific timing.

The maximal anabolic dose per meal to maximize muscle protein synthesis (MPS) is approximately 0.4 to 0.6 grams per kilogram of body weight.

The traditional “anabolic window” (consuming protein immediately post-workout) is a secondary concern if daily totals are met.

Research shows no significant difference in muscle size or strength between immediate post-workout protein and waiting several hours.

Nutrients from pre-workout meals remain in circulation, providing a functional reservoir during and after resistance training.

Flexibility in meal distribution allows individuals to stack protein at dinner without compromising body composition or health goals.

Timeline

Optimal Protein Dosing per Meal

The speaker introduces the concept of the maximal anabolic dose of protein required to trigger muscle protein synthesis (MPS) effectively. Based on research by Brad Schoenfeld, the recommended dose is roughly 0.4 to 0.6 grams per kilogram, or 0.2 to 0.25 grams per pound of body weight per meal. This calculation suggests that for most individuals, a dose between 30 to 50 grams of protein will max out the muscle's anabolic response. The discussion establishes that while per-meal dosing matters for optimization, it is still secondary to the total amount of protein consumed throughout the day. This section sets the stage by defining the “freedom units” and metric measurements necessary for viewers to calculate their own needs.

Debunking the Anabolic Window

This section addresses the common anxiety regarding the “anabolic window” and whether protein must be consumed immediately after resistance training. A meta-analysis of various studies revealed that as long as total daily protein reaches at least 1.6 to 1.7 grams per kilogram, the specific timing relative to the workout does not significantly impact results. The speaker explains that unless a person is training in a completely fasted state after many hours of neglect, there are usually nutrients still circulating in the system. This provides a “reservoir” of amino acids and glycogen that the body can draw from during and after exercise. The takeaway is that the urgency to rush a protein shake within minutes of finishing a set is largely unnecessary for the general population.

Protein Distribution and Practical Lifestyle Application

The conversation shifts to the practical challenges of distributing protein evenly throughout the day, especially for those with busy schedules. Many people naturally eat a larger dinner, and the speaker confirms there is nothing fundamentally wrong with stacking protein toward the end of the day. A study by Yassine Locke is cited, which compared immediate pre- and post-workout protein intake against a six-hour window of nutrient neglect around the training bout. The results showed no meaningful difference in muscle size or strength gains over a 10 to 12-week period when total protein was optimized. This evidence supports the idea that lifestyle flexibility is possible without sacrificing physical progress. It reassures trainees that they can focus on their total daily targets rather than rigid, inconvenient schedules.

The Hierarchy of Protein Importance

The final segment summarizes the hierarchy of importance for muscle building, using a cake and icing analogy. The speaker emphasizes that total daily protein, ranging from 0.7 to 1.0 grams per pound, represents the “cake” or the essential foundation of the diet. Specific timing and the exact amount in a single meal are described as a “very thin layer of icing” on that cake. There is a distinction made between when a person ingests protein and when those amino acids are actually available in the bloodstream. Understanding that digestion takes time helps explain why a pre-workout meal can effectively cover the post-workout period. The video concludes by reiterating that while timing can be a tool for optimization, it should not be a source of stress for most fitness enthusiasts.
