1. Why 30 Grams Per Meal Is the Sweet Spot
During a calorie deficit, your body decides whether to pull energy from stored body fat or lean muscle tissue. Hitting roughly 25 to 40 grams of high-quality protein at 3 to 4 meals per day provides the ~2.5–3.0g leucine threshold needed to stimulate muscle protein synthesis AND keeps satiety hormones (GLP-1 and PYY) elevated for hours.
2. Combining Lean Anchors with Budget Staples
You don’t need expensive supplements to hit 130–160g of protein per day. Pair one lean anchor per meal (chicken breast, canned tuna, 0% Greek yogurt, cottage cheese, egg whites, or firm tofu) with fiber-rich sides.
