This Is How Much Protein You REALLY Need | Dr. Rhonda Patrick

Summary

In a detailed discussion, Dr. Rhonda Patrick unveils the complexities and misconceptions surrounding optimal protein intake. Contrary to the widely accepted RDA of 0.8 grams per kilogram, Dr. Patrick suggests that higher intakes ranging from 1.2 to 1.6 grams per kilogram are more suited for muscle maintenance and growth. She emphasizes tailored protein needs based on individual goals such as muscle building, maintenance, and body recomposition. Dr. Patrick also tackles myths about high protein intake's potential kidney damage and highlights the flexibility in protein consumption timing, urging a focus on overall daily intake instead. The insights include considerations for pre-sleep protein consumption and its benefits for those engaged in regular resistance training, challenging preconceived notions about the so-called anabolic window and protein utilization limits.

Highlights

• The RDA for protein (0.8g/kg) is often too low for optimal health and muscle gain 🔍
• For muscle growth, 1.6g/kg seems ideal, especially with resistance training 🏋️‍♂️
• Protein intake above RDA can prevent frailty and enhance longevity in older adults ⏳
• Consuming high protein is safe and may offer benefits even for those with kidney disease 🧠
• The supposed 'anabolic window' is less critical than once thought; focus on overall intake 🕰️

Key Takeaways

• Optimal protein needs vary based on goals: muscle building, maintenance, or recomposition 💪
• Higher protein intake (1.2 to 1.6g/kg) is more effective than the RDA's 0.8g/kg recommendation ⚖️
• High protein intake is safe for healthy kidneys and may benefit those with chronic kidney issues 🥩
• Total daily protein intake is more critical than timing individual meals ⌛
• Pre-sleep protein can enhance muscle recovery for those in resistance training 💤

Overview

Dr. Rhonda Patrick provides a comprehensive exploration into the world of protein intake, shaking up the traditional viewpoint with evidence-backed arguments. She challenges the standard RDA of protein, underscoring its inadequacy for most goals related to muscle health and gives an insightful peek into the tailored protein needs for muscle building, maintaining, or recomposition.

Highlighting various studies, Dr. Patrick reassures that high-protein diets are safe for kidneys, dismissing long-held fears of kidney damage among healthy individuals. The insight she provides about the body's adaptability to protein distribution and timing shatters the elusive anabolic window myth, emphasizing that an evenly distributed protein intake throughout the day is beneficial but not absolutely necessary.

For those dedicated to resistance training, Dr. Patrick talks about the added advantage of pre-sleep protein intake, revealing its potential to aid muscle recovery without affecting next-day appetite. Her perspective encourages a shift from rigid meal timing to a more flexible, daily total intake approach, ensuring protein goals align efficiently with individual lifestyle and training demands.

• 00:00 - 00:30 so let's talk about the optimal protein intake the optimal amount of protein will not be the same for everyone some people want to build muscle mass some people want to maintain it and others want to improve their body composition by building muscle and losing fat each of these goals requires a more tailored approach the first thing to know is that it's generally agreed upon that protein needs should be calculated based on a lean body mass or an adjusted body weight reflecting a healthy body fat percentage so for example 12 to 15% for
• 00:30 - 01:00 men and around 20% for women this prevents unrealistic targets especially for those who are overweight or obese so when I refer to protein intake in grams per kilogram of body weight per day what I'm ideally referring to is your ideal or goal body weight let's address one thing up front the recommended dietary allowance or the RDA for protein of 0.8 gam per kilogram per day is thought by many to be too low this is because the r
• 01:00 - 01:30 a was derived from nitrogen balance studies which have limitations due to incomplete collection and inaccurate estimates of amino acid losses the optimal range for daily protein intake is closer to 1.2 to 1.6 gram per kilogram body weight per day or roughly 0.54 to 0.72 G per pound this is based on alternative methods like stable isotope studies which consistently show that higher intakes are necessary to
• 01:30 - 02:00 maintain a positive protein balance far above the 0.8 G per kilogram often cited so aiming for at least 1.2 G and up to 1.6 G is what we're talking about for optimal protein intake there's good evidence to suggest this for example older adults consuming at least 1.2 grams of protein per kilogram body weight per day prevented age related losses in lean mass when compared to consuming the RDA of 0.8 G per kilog body weight old older women were also
• 02:00 - 02:30 30% less likely to experience Frailty when consuming protein above the RDA so what is the optimal protein intake for building muscle while resistance training for people engaged in resistance training a protein intake of 1.6 gram per kilogram body weight per day has been shown to maximize gains in lean body mass with a 27% increase in muscle mass over even a 1.2 gram per kilogram intake that's a lot and it
• 02:30 - 03:00 really just serves to really underscore how low the RDA really is when you're talking about 0.8 grams per kilogram body weight by the way for an excellent discussion of the protein RDA and much more see my interview with Dr Stuart Phillips in episode 76 of the found my fitness podcast there are special circumstances where even a higher protein intake might offer some marginal benefit the first example is people undergoing body recomposition where they are in an energy dep deficit to lose fat
• 03:00 - 03:30 Mass while preserving or even increasing muscle mass so let's talk a little bit more about body recomposition and weight loss a higher protein intake tends to improve satiety it helps you feel Fuller for longer and may help prevent overeating for people who want to lose weight this is a major benefit eating more protein is also essential during weight loss to prevent the loss of lean body mass when you eat a higher protein calorie restricted diet more weight loss comes from fat mass than muscle mass but
• 03:30 - 04:00 remember resistance training is also important to prevent the loss of lean mass high protein diets may also cause a slight increase in the metabolic rate due to the thermic effect of food helping you burn a few more calories throughout the day the second example where a higher protein intake above 1.6 gram per kilogram may be beneficial is with professional athletes where extremely marginal improvements in muscle protein synthesis gives them an edge on competition so in this scenario this is where up to 2.2 gam of protein per kilogram per day or one gram per
• 04:00 - 04:30 pound May provide marginal benefits despite common misconceptions a very high protein intake is not harmful to Kidney Health in people without pre-existing kidney conditions research consistently shows that high protein diets are safe for most people and any concerns over kidney damage are largely unfounded so let's talk about this myth early interpretations of certain studies suggested that excessive protein intake might overwork the kidneys while protein restriction can slow the progression of
• 04:30 - 05:00 kidney disease in some individuals we now know this does not imply that a healthy people should limit their protein consumption higher protein diets do induce changes in kidney function but they do not overburden the kidneys The observed increase in markers and kidney function is a normal adaptive response to eliminate Ura and other waste products generated during protein metabolism this is entirely normal for individuals with healthy renal function so current evidence does not support an association between higher protein
• 05:00 - 05:30 intake and kidney disease among healthy adults or those at risk such as individuals with obesity hypertension or even diabetes moreover research and athletes has shown that consuming protein intakes as high as 3.2 to 4.5 grams per kilogram of body weight per day for up to one year does not cause any adverse changes in kidney function and is considered safe this intake is four to six times higher than the RDA for protein and emerging research even
• 05:30 - 06:00 suggests that higher protein intake may actually be beneficial for people with chronic kidney disease some Studies have found that consuming protein at levels above the RDA is associated with reduced mortality risk in this population challenging the traditional approach of protein restriction the bottom line we can finally put to rest the myth that high protein diets harm healthy kidneys it's time to tackle another important aspect of protein intake and that's how often and when we should consume it
• 06:00 - 06:30 we'll tackle two key points first how we consume our daily protein intake whether we should spread it evenly across 3 to four meals or load it up into one or two meals second and related does protein have to be consumed within a critical anabolic window or timed with our workouts in short the answer to both of these is that factors are less important overall than you might expect emerging evidence reveals that the body can effectively utilize even very large protein doses this challenges the notion
• 06:30 - 07:00 that protein must be meticulously spread over multiple meals to maximize muscle protein synthesis even though an even daily protein distribution is ideal this doesn't mean that consuming the same total amount of protein in fewer high protein meals is ineffective protein distribution is important but not vital when you eat a larger dose of protein it takes longer to digest but your body will eventually use it this is contrary to what some people think happens when you consume more than 20 to 25 grams of
• 07:00 - 07:30 protein in a single meal they think that the excess protein will just be excreted by the body and otherwise wasted in fact a study by Dr Luke vanloon and colleagues found that consuming 100 grams of protein after exercise led to a more robust and prolonged anabolic response than did 25 grams of protein but had negligible effects on amino acid oxidation the conclusion from this study was quote the magnitude and duration of the anabolic response to protein has no upper limit in humans and has been
• 07:30 - 08:00 severely underestimated end quote this dispels a few myths about how the body can use only 20 to 25 grams of protein at once as a practical takeaway a more evenly distributed pattern of protein intake throughout the day is probably what we should be striving for but evidence like this highlights why more and more experts seem to be aligning on the simple fact that the vast majority of us athletes or not should be thinking about protein intake from the standpoint
• 08:00 - 08:30 of total daily intake with less overall focus on factors like timing or the per meal intake another question that people have regarding protein timing is whether protein needs to be consumed immediately after exercise to enhance the effects of training this idea is known as the anabolic window the anabolic window is a period after exercise typically lasting from 30 minutes to 2 hours during which the body is primed to absorb and utilize nutrients particularly protein and carbohy hydrates for muscle repair and
• 08:30 - 09:00 growth it occurs because the body's ability to synthesize protein and replenish glycogen stores is heightened aided by exercise induced hormonal changes like increased insulin levels consuming 20 to 40 grams of high quality protein often paired with carbohydrates can enhance Muscle Recovery and growth during the anabolic window or so it was one's thought recent scientific evidence reveals that muscle protein synthesis remains significantly elevated for a full 24 hours following exercise
• 09:00 - 09:30 effectively debunking the notion of a very narrow anabolic window lasting only a few hours furthermore supplementing with protein before exercise has the same effects on body composition and strength compared to supplementing with protein immediately after exercise in other words there are no meaningful differences between pre and post exercise protein ingestion this means that you're free to choose when you want to consume protein in relation to exercise so long long as your total
• 09:30 - 10:00 daily intake of protein is adequately High to support optimal muscle protein synthesis of course there is definitely no downside to consuming protein immediately after a workout especially for people interested in achieving marginal gains in strength or muscle mass to wrap up our discussion on protein timing and distribution I want to bring up one more strategy to help with muscle building that relates to protein distribution and timing pre- sleep protein there's two ways to look at this one way is through the lens of Tim restricted eating and the other is through the lens of actively optimizing
• 10:00 - 10:30 for muscle protein synthesis on training days it's been shown in Studies by Dr Luke Van L and colleagues that protein consumed before bed is digested and absorbed overnight it also increases overnight muscle protein synthesis rates and improves net protein balance in people who had performed resistance training earlier in the day to enhance Muscle Recovery the benefits of pre-sleep protein have also been shown during chronic resistance exercise training consuming about 30 grams of protein before bed every night while
• 10:30 - 11:00 resistance training appears to increase muscle mass and muscle strength another thing about pre-sleep protein is that it does not seem to reduce appetite or diminish the muscle protein synthesis response at breakfast the next morning which may have been a concern for some people overall I think pre-sleep protein is just one way to increase total daily protein intake if you don't like going to bed hungry having a low calorie protein shake on training days may have the benefit of potentially enhancing
• 11:00 - 11:30 your muscle gain on those training days but don't use this as an excuse to go wild we should still be mindful about the fall and insulin sensitivity that happens as we get close to our habitual bedtime and this is particularly true if you're not actively training so let's summarize some key points about protein timing and distribution first while it's not necessary to consume protein immediately after a workout there's no harm in doing so for those who exercise fasted having a protein Rich meal right
• 11:30 - 12:00 after may be beneficial ultimately total daily protein intake is the most crucial Factor second evenly Distributing protein across meals is ideal but your body can use even large protein meals and finally consuming protein before bed isn't essential but it can be a helpful strategy to boost total daily intake or support Muscle Recovery especially in those who are actively training
