Energy Deficit

Definition

An energy deficit occurs when you consume fewer calories than your body needs to maintain its current weight, leading to weight loss.

Scientific / Technical Definition

An energy deficit is a state where the total caloric intake is less than the total daily energy expenditure (TDEE), resulting in a negative energy balance. This triggers the body to utilize stored energy reserves, such as fat and muscle tissue, to meet energy demands.

Benefits

• Facilitates weight loss.
• Can improve metabolic health.
• May reduce risk of obesity-related conditions.

Examples

• Reducing daily calorie intake while maintaining physical activity levels.
• Incorporating more physical activity to burn more calories than consumed.

Additional Information

• effects: Energy deficit can lead to fat loss as the body uses stored fat for fuel. However, prolonged energy deficits without adequate nutrition can cause muscle loss and nutrient deficiencies.
