We read the studies. You get the answers.

Every protein calculator on the internet runs the same equation: take your body weight, multiply by a number between 1.2 and 2.0, and eat that many grams per day. At 85 kilograms (187 lbs), the math is manageable. At 120 kilograms (265 lbs), it spits out a target north of 190 grams — a number that would require protein at every meal, a shake between meals, and the quiet acceptance that your entire diet now revolves around hitting a quota your gut says can't be right.

You upped your protein. More chicken at dinner, Greek yogurt at breakfast, maybe a shake after training. The advice landed years ago — eat more protein at each meal as you age — and you followed it. The grams went up. The meals got deliberate. And as far as you could tell, the strategy was working. What nobody mentioned is that total grams are only half the story. Inside every serving of protein, one specific amino acid acts as the trigger for muscle building, and that trigger does not fire at the same threshold in every body.

Resistant starch feeds good gut bacteria. That claim has settled into the kind of certainty that stops generating questions — a prebiotic reaches the colon, bacteria feed on it, the good ones multiply, the gut improves. Most people who cool their rice or reheat their pasta carry this model without noticing how blurry it actually is.
