Protein timing throughout the day - does it matter?
I usually eat most of my protein at dinner because it's my biggest meal. Friend says I should spread it out across the day for "maximum muscle protein synthesis." Is this actually important or overthinking?
There IS evidence that distributing protein across 3-4 meals (30-40g each) optimizes muscle protein synthesis compared to eating it all at once. Each meal triggers MPS, and there's a cap per meal of about 0.4-0.55g/kg bodyweight.
That said, this is OPTIMIZATION, not make-or-break. Total daily protein matters way more than distribution. If you eat 160g all at dinner vs spread across 4 meals, the difference is maybe 5-10% at most.
For the average person: doesn't matter much. For competitive athletes trying to squeeze out every advantage: yes, distribute it. Most of us are not at the level where this makes a meaningful difference.
I split mine into 4 meals of ~45g each. But I've been training for 8 years and I'm past the stage where basic stuff makes a difference. For newer lifters, just hit your total daily target. Period.
Practical approach: have protein at every meal. Eggs at breakfast, chicken at lunch, meat at dinner, maybe a shake somewhere. That naturally distributes it without overthinking.
Interesting because IF means I eat all my protein in an 8-hour window. My muscle gains have been fine. So while distribution might be optimal, it's clearly not essential.
The "30g protein per meal" limit is a myth btw. Your body will absorb more than that. The MPS ceiling is about efficiency of use, not absorption. You won't waste protein by eating more at once.
Ok so total daily intake >> timing. Got it. I'll try to have some protein at every meal but I won't stress about perfect distribution. Thanks for clearing this up.
The one timing thing that MIGHT matter: having protein before bed (casein or cottage cheese). Some evidence it helps overnight recovery. Easy to do and low cost.
