A first estimate from your profile.
When you start, Holymp calculates an initial calorie need from your data and your goal, so you can begin right away.
HOLYMPCalorie formulas are only a starting point. Holymp estimates your maintenance calories from what you actually eat and how your weight changes, then suggests how to adapt calories and macros.

Formulas start from age, sex, height, weight and activity level. Two people with the same data can need a few hundred calories more or less: that is why you can follow the “right” target and see no change on the scale.
When you start, Holymp calculates an initial calorie need from your data and your goal, so you can begin right away.
Week after week Holymp compares the calories you log with your weight trend and works out how many you really burn, with a reliability indicator.
When your weight is not moving in the direction you chose, Holymp suggests a small calorie and macro adjustment. You see it first and decide whether to apply it.
If your diary has too many empty days or there are few weigh-ins, Holymp does not invent a number: it tells you what it needs for a reliable estimate.
A weekend out or a few days of water retention do not trigger adjustments: Holymp waits until the data is readable again.

The calories at which your weight stays stable, also called TDEE (total daily energy expenditure). Eat less and you lose weight, eat more and you gain.
