Your Legs Stop Using Protein Past 60 — Until Meals Hit 30g

Past 60, your leg muscle stops answering the protein you eat — unless each meal crosses about 30 grams. Most breakfasts don't.
The research calls it anabolic resistance: older thigh muscle still hears amino acids after a meal, but it needs a far louder signal before it builds anything. Below roughly 30 grams of protein per meal, much of what you eat is burned as fuel instead of becoming leg. This video walks through the dose-response work in the Journals of Gerontology, a one-year trial in the American Journal of Clinical Nutrition, and a ten-day bed rest experiment that shows how fast strength leaves when meals fall short — then gives you the chair test and the one meal to fix first.
