How This Macro Split Is Actually Built
Most macro calculators pick a flat percentage split, like 40/30/30, and apply it to everyone regardless of size. That approach breaks down badly for anyone significantly lighter or heavier than average. This calculator builds macros the way a real coach would: protein first, set in grams per kilogram of a sensible reference bodyweight, fat next as a percentage of calories with a floor for hormonal health, and carbs get whatever calories are left over.
1. Total calories = TDEE adjusted for your goal
2. Protein = 1.4-1.9g per kg of reference bodyweight (higher for fat loss, adjusted if you carry excess weight)
3. Fat = ~25% of total calories
4. Carbs = whatever calories remain, divided by 4
This is the exact same nutrition engine that builds a real member's plan inside the SanoobFit app, including the reference-bodyweight adjustment for protein, not a simplified marketing version.
Macros are a compass, not a cage. Total calories decide whether you gain or lose weight. Your macro split decides how that weight change actually looks and feels, how full you stay, and how much muscle you keep. Get close most days and stop chasing perfect ones.
Inside SanoobFit's APEX system, showing up at your macro targets consistently is tracked as the Nutrition Adherence standard, central to advancing out of Stage 1, Foundation, and to the Recomposition program.
