Frequently Asked Questions
How many calories do I need per day?
Daily calorie needs depend on age, gender, weight, height, and activity level. Average adults need about 2,000 calories (women) to 2,500 calories (men) per day for weight maintenance.
How do I calculate a calorie deficit for weight loss?

What is the Calorie Calculator?
The calorie calculator computes your daily energy requirement from basal metabolic rate and activity level (PAL).
How does the Calorie Calculator work?
Enter sex, age, weight, height and activity level. The basal rate is calculated using the Mifflin-St Jeor formula and multiplied by the PAL factor. For weight loss a deficit of 300-500 kcal is recommended.
