8/13/26: Why Timing Your Protein Matters More Than You Think

8/13/26: Why Timing Your Protein Matters More Than You Think14 aug4 min

<p>Most people think protein is just about hitting a number — 100 grams, 150 grams, whatever your app tells you. But if you&#39;re over 40, *when* you eat that protein might matter almost as much as how much. Let me explain why.</p><p><br></p><p>Here&#39;s something most people don&#39;t know: your body can only use so much protein at once to build and repair muscle. Research suggests there&#39;s a ceiling — somewhere around 30 to 40 grams per meal — where muscle protein synthesis maxes out. Eat way more than that in one sitting, and the extra doesn&#39;t just pile onto muscle-building. So if you&#39;re eating one huge protein-loaded dinner and skipping it the rest of the day, you&#39;re leaving a lot on the table.</p><p><br></p><p>Here&#39;s where it gets more important as we age. There&#39;s a phenomenon called anabolic resistance — basically, older muscle doesn&#39;t respond to protein as efficiently as younger muscle. That means the same 20 grams that triggered a strong response at 25 might not do much at 65. The fix isn&#39;t complicated: slightly larger protein servings, spread more evenly across the day.</p><p><br></p><p>In practice, this looks like three things. First — breakfast. Most people&#39;s most protein-poor meal. A couple eggs won&#39;t cut it if you&#39;re trying to hit that per-meal threshold. Second — post-exercise. Your muscles are primed to use protein efficiently in that window after training. Third — before bed. A slower-digesting protein source overnight can help offset the natural muscle breakdown that happens while you sleep.</p><p><br></p><p>Why do I care about this as a neuromotor trainer and not just a nutrition coach? Because muscle loss — sarcopenia — isn&#39;t just a cosmetic issue. It&#39;s directly tied to balance, fall risk, and functional independence as we age. Every client I work with on neuromotor rehab benefits from having the raw materials — protein — to actually build back what we&#39;re training.</p><p><br></p><p>So here&#39;s your takeaway: stop thinking about protein as one number for the day. Think about a palm-sized portion, at every meal. That&#39;s the shift that actually moves the needle</p>
