What This Number Actually Is

Your calorie target is not a verdict, it is a hypothesis. It starts from your Total Daily Energy Expenditure, the calories your body burns in a real day, then adjusts up or down based on your goal. Eating at that number maintains your current weight. A moderate deficit below it produces fat loss. A modest surplus above it supports building muscle.

Steps
1. BMR (Mifflin-St Jeor): 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5 (men) or - 161 (women)
2. TDEE = BMR × Activity Multiplier
3. Fat loss target = TDEE × 0.82  |  Muscle gain target = TDEE × 1.10

This is the exact calculation the SanoobFit app uses to build a real member's nutrition plan, down to the same rounding.

The SanoobFit Position

Consistency, not intensity or perfection, is the mechanism of change. The number below is a starting point to test for two to three weeks, not a target to hit perfectly every single day. Someone who eats close to their number most days, most weeks, will out-progress someone chasing an exact number some days and abandoning it on others.

Where This Fits in APEX

Inside SanoobFit's APEX system, showing up at your target consistently is tracked as the Nutrition Adherence standard. Real, sustained adherence is a requirement for advancing out of Stage 1, Foundation, and it is central to the Recomposition program.

Standard: Nutrition Adherence Stage 1: Foundation Program: Recomposition

A Number Alone Is Not a Plan

The SanoobFit app turns this target into real meals, real tracking and a plan that adjusts as you go, free to start.

Frequently asked questions

How many calories should I eat a day?
It depends on your goal. Eating at your TDEE maintains weight, eating below it in a moderate deficit produces fat loss, and eating slightly above it supports muscle gain. This calculator shows all three based on your own stats.
What is a calorie deficit?
A calorie deficit means eating fewer calories than your body burns in a day (your TDEE), so it draws on stored energy, mainly body fat, to make up the difference. A moderate deficit is what produces fat loss.
