Certaintyexplicitstrong endorsement -
Engage in regular resistance training to build and maintain muscle mass and strength, especially as you age, to prevent sarcopenia and frailty.
“resistance training is the most important factor for building and maintaining muscle mass
Certaintyexplicitstrong endorsement -
Older adults should consume larger protein doses per meal (~0.4 g/kg, or ~30–35 g) to overcome anabolic resistance and maximally stimulate muscle protein synthesis.
“older adults who need about 0.4 grams of protein per kilogram
Dosage~0.4 g/kg per meal (~30–35 g for 80 kg adult)Certaintyexplicitrecommendation -
Even nonagenarians can gain substantial strength with high-intensity strength training; it's never too late to start.
“eight weeks of high intensity strength training produced a 174% increase in muscle strength
Certaintyexplicitstrong endorsement -
Aim for 1.2 to 1.6 g protein per kg body weight per day for general health, above the RDA of 0.8 g/kg.
“optimal range for daily protein intake is closer to 1.2 to 1.6 grams per kilogram
Dosage1.2–1.6 g/kg body weight/day, calculated on lean/ideal body weight (12–15% BF men, ~20% BF women)CaveatsUse ideal/lean body weight for calculation, not current weight if overweightCertaintyexplicitstrong endorsement -
For people doing resistance training or in a calorie deficit aiming for body recomposition, aim for 1.6 g/kg/day, up to ~2.2 g/kg/day for professional athletes.
“1.6 grams per kilogram body weight per day has been shown to maximize gains
Dosage1.6 g/kg/day baseline; up to 2.2 g/kg/day (1 g/lb) for elite athletesCertaintyexplicitstrong endorsement -
Distribute protein across 3–4 meals/day with ~20–25 g (or 20–30 g for older adults) of high-quality protein per meal to support muscle protein synthesis.
“evenly distributed pattern of protein intake throughout the day is probably what we should be striving for
Dosage3–4 meals/day, 20–25 g protein/meal (20–30 g for older adults)CaveatsTotal daily protein is more important than distributionCertaintyhedgedrecommendation -
The anabolic window myth is debunked — protein can be consumed before or after workouts with similar effects; total daily intake matters most.
“no meaningful differences between pre and post exercise protein ingestion
DosageMPS elevated for 24 hours post-exerciseCaveatsFasted exercisers may benefit from post-workout proteinCertaintyexplicitrecommendation -
Consuming ~30 g of protein before bed on training days enhances overnight muscle protein synthesis and recovery without impairing breakfast MPS or appetite.
“Consuming about 30 grams of protein before bed every night while resistance training appears to increase muscle mass
Dosage~30 g protein before bed on training daysCaveatsBe mindful of insulin sensitivity decline near bedtime if not actively trainingCertaintyexplicitrecommendation -
Alternative
BCAA supplements can be used to ensure adequate leucine intake if needed.
“adding whey protein or branched-chain amino acid supplement to your diet
Certaintyhedgedoffhand mention -
Animal proteins (meat, dairy) are superior for maximizing muscle protein synthesis due to higher protein density, digestibility, and complete amino acid profile.
“animal-sourced protein is better
Dosage~70 g chicken or beef provides 20 g proteinCertaintyexplicitrecommendation -
Sprouting and fermenting plant foods can improve digestibility and absorption of plant protein.
“Sprouting and fermenting can overcome some of this and improve the digestibility
Certaintyexplicitoffhand mention -
Alternative
Vegetarians/vegans can meet protein needs by supplementing with plant protein isolates/concentrates, diversifying sources, and consuming more total protein.
“supplementing with plant-based protein isolates and concentrates
DosageHigher total daily intake to compensate for lower qualityCertaintyexplicitrecommendation -
Whey protein is an excellent high-quality, rapidly-digested protein source rich in leucine, ideal post-exercise or to boost intake.
“whey protein is more rapidly digested and stimulates muscle protein synthesis more effectively
Dosage~20 g provides 2–3 g leucine sufficient to saturate MPSCertaintyexplicitstrong endorsement -
Alternative
Casein provides slow, prolonged amino acid release, useful for sustained MPS over time (e.g., before bed).
“casein provides a prolonged release of amino acids
Certaintyexplicitrecommendation -
Collagen is a poor protein for stimulating muscle protein synthesis because it lacks essential amino acids like leucine.
“collagen does not significantly enhance muscle protein synthesis
CaveatsSuboptimal as a primary protein source for muscle buildingCertaintyexplicitmild caution -
Don't drastically restrict protein to lower IGF-1; too-low IGF-1 has its own risks including brain matter loss, and U-shaped mortality curve shows both extremes are harmful.
“Lowering IGF-1 too much can come with its own set of risks
CaveatsRecommendations against high protein from longevity school may not apply to active individualsCertaintyexplicitmild caution
