BMR (Basal Metabolic Rate) is the number of calories your body needs to maintain basic physiological functions at rest, like breathing and digestion.

How do I calculate my daily calorie needs?

Daily calorie needs can be estimated by multiplying your BMR with an activity factor. This gives your TDEE (Total Daily Energy Expenditure), which helps determine maintenance, weight loss, or weight gain calories.

How many calories should I eat to lose weight?

To lose weight, you should consume about 15–20% fewer calories than your TDEE. This creates a caloric deficit necessary for weight loss.
