1. What is the NHS Calorie Recommendation?

The NHS recommends a calorie deficit approach for sustainable weight loss. For the average woman, this typically means reducing daily intake by about 500 calories from a maintenance level of 2000 calories.

2. How Does the Calculator Work?

The calculator uses the NHS recommended formula:

Where:

• Maintenance Calories — Your current daily calorie intake to maintain weight
• Calorie Deficit — The reduction in calories needed for weight loss (typically 500 kcal/day)

Explanation: A deficit of 500 calories per day typically results in about 1 pound (0.45kg) of weight loss per week, which is considered a safe and sustainable rate.

3. Importance of Calorie Deficit for Weight Loss

Details: Creating a calorie deficit is the fundamental principle behind weight loss. The NHS recommends gradual weight loss through moderate calorie reduction combined with increased physical activity.

4. Using the Calculator

Tips: Enter your current daily calorie intake and your desired calorie deficit. The NHS typically recommends a 500-calorie deficit for sustainable weight loss. All values must be positive numbers.
