Frequently Asked Questions
How many calories should I eat per day?
Daily calorie needs vary based on age, gender, weight, height, and activity level. The average adult needs 1,600-2,400 calories (women) or 2,000-3,000 calories (men) per day. Use our calculator for a personalized estimate.
What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, including your BMR (Basal Metabolic Rate) plus calories burned through physical activity and digestion. It's the key number for weight management.
How many calories to lose weight?
A common guideline suggests that a calorie deficit of approximately 500 calories per day below your TDEE may lead to about 1 pound of weight loss per week. However, individual results vary significantly based on metabolism, body composition, and other factors. Very low-calorie diets can be harmful. Always consult a healthcare provider or registered dietitian before making significant dietary changes.
