Protein distribution is how you spread your daily protein across meals. The same 140 grams can land as one massive dinner or as four servings of 35 grams, and the split matters. Each meal with 25 to 40 grams of quality protein triggers a fresh round of muscle protein synthesis, so hitting that dose three or four times a day builds more muscle than front-loading it all into one sitting.
Why it matters
Muscle protein synthesis works in pulses. A protein-rich meal switches it on for a few hours, then it fades, and it won't fire again until the next real dose arrives. Here's the catch: a bigger dose doesn't buy a proportionally bigger pulse. Past roughly 40 grams, the extra protein mostly gets used for other things. So the classic pattern (coffee for breakfast, small lunch, 90-gram protein dinner) wastes chances. You flipped the switch once when you could've flipped it four times.
How to use it in training
Set your daily target first. Then divide by three or four. For a 180-pound lifter aiming at 140 grams, that's about 35 grams per meal.
Breakfast is where most people fall short, so fix that meal first. Eggs with Greek yogurt, a protein shake with oats, cottage cheese and fruit. Any of those gets you to 30-plus grams before noon. And don't stress about eating every three hours on the dot. Roughly even spacing across your normal meals is the whole trick.
