How Calorie Deficit Works: The Ultimate Guide

To lose body fat, you must be in a calorie deficit. Let's explore the science behind it.

🔥 The Physics of Weight Loss

A calorie deficit means you consume fewer calories than your body burns. If your Total Daily Energy Expenditure (TDEE) is 2200 kcal and you eat 1700 kcal, the 500 kcal difference forces your body to break down stored fat tissue for fuel.

📈 Sustainable Deficits

Drastic calorie cuts can harm your metabolism and burn muscle. Keep your deficit moderate (300 to 500 kcal). Track your meals instantly using CalorIA to make sure you stay in the optimal fat-burning zone.
