How many calories should I eat per day?

A 30-year-old man weighing 70 kg, 175 cm tall, with light activity needs approximately 2,150 calories/day to maintain weight. To lose 0.5 kg per week, eat 500 calories less (about 1,650/day). To gain 0.5 kg per week, eat 500 calories more (about 2,650/day).

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest — about 60-75% of your daily burn. TDEE (Total Daily Energy Expenditure) multiplies BMR by an activity factor (1.2 for sedentary to 1.9 for very active) to estimate total daily calories burned.

How many calories below TDEE should I eat for weight loss?

A deficit of 500 calories per day below your TDEE produces roughly 1 pound of fat loss per week, since one pound of fat contains approximately 3,500 calories. A 1,000-calorie daily deficit doubles that rate but should not be sustained without medical supervision, as it risks muscle loss and metabolic adaptation.
