Carbs, Protein, Fat: Finding the Macro Ratio That Fits Your Life

Decades of dietary trials show roughly the same thing: when calories and protein are equated, low-carb and low-fat diets produce nearly identical outcomes for fat loss and metabolic health over a year. Adherence — not the ratio — is the variable that matters.

Protein: 1.4–1.8 g/kg/day. Fat: 0.8–1.2 g/kg/day to support hormones, with at least 20% of calories from fat as a floor. Carbohydrates: everything that is left, scaled to training volume.

Athletes and endurance runners benefit from more carbohydrate (40–60% of calories). Sedentary office workers do well in the 25–40% range. Both are valid; both work; the test is whether you actually want to eat this way for a year.

Whole foods first. Minimise ultra-processed products. Hit your protein floor reliably. Then choose a carb/fat split that fits your cravings, your culture, your training, and your kitchen.
