Protein math and meal plan
High‑protein snack targets: 20–25 g protein, 100–150 kcal, and 2–3 g leucine to trigger muscle synthesis — and example full days include a 2,200‑calorie, 200 g protein plan (egg‑white/oats/berries breakfast; chicken, rice & beans lunch; Greek yogurt + whey snack; lean beef and potatoes for dinner).

The International Society of Sports Nutrition’s position review frames leucine as the acute “trigger” and recommends acute protein doses contain roughly 0.7–3.0 g of leucine, with many researchers placing the practical per‑meal threshold for younger adults at about 2.5–3.0 g and older adults often needing 3–4 g. (link.springer.com; healthline.com). A commercial benchmark: one rounded scoop of Optimum Nutrition Gold Standard typically delivers ~24 g protein and ~120 kcal per serving and its amino‑acid profile supplies multiple grams of leucine per scoop, which is why whey isolates are commonly used to hit per‑meal leucine targets. (optimumnutrition.com; comparewhey.org). Plain nonfat Greek yogurt in common single‑container sizes (about 170 g) provides roughly 16–17 g protein and ~90 kcal, making it a compact base that, when combined with a small whey addition, can deliver a high leucine load without large extra calories. (nutritionvalue.org; nutritionix.com). Food‑level leucine data show animal proteins give the leucine trigger with less volume: chicken breast and many lean beef cuts deliver roughly 2.3–2.8 g leucine per 100 g serving, while egg‑white portions and dairy have measurable leucine concentrations that influence how much food is needed to hit the threshold. (optimisingnutrition.com; myprotein.com). Basic calorie math anchors the plan: protein contributes 4 kcal per gram under the Atwater system used on labels and in databases, so each additional 10 g of protein raises a day’s calories by about 40 kcal. (nal.usda.gov; proteinjug.com). For context on totals, the ISSN recommends a practical daily range for many exercising people of about 1.4–2.0 g protein per kilogram body weight, a guideline that explains why structured, high‑protein daily menus skew heavily toward protein grams and leucine‑rich servings.
