FAQ

Common questions about this topic

What is a calorie deficit?

A calorie deficit means eating fewer calories than you burn over time, which is the basic condition required for fat loss.

How big should my calorie deficit be?

It depends on the person, but moderate deficits are often easier to maintain and protect performance better than aggressive cuts.

Does a calculator predict exact weight loss?

No. It gives a directional estimate. Real results vary because body weight shifts for many reasons beyond fat alone.
