Calorie Deficit
Definition: Consuming fewer calories than your body burns (TDEE), forcing it to use stored energy (fat) for fuel. A deficit of 500 calories/day results in approximately 0.5kg of fat loss per week.
Detailed Explanation
A calorie deficit occurs when your energy intake is lower than your energy expenditure, forcing your body to draw upon stored energy reserves (predominantly body fat) to meet its metabolic demands.
Practical Application & Guide
Aim for a moderate, sustainable deficit of 300 to 500 calories below your TDEE. This supports gradual fat loss of 0.25kg to 0.5kg per week while preserving valuable muscle mass.
Common Pitfalls & Mistakes
Creating a deficit that is too aggressive, which triggers muscle loss, extreme hunger, hormone disruption, and eventual diet abandonment.
