Calorie Calculator

If you are asking how many calories should I eat to lose weight, a practical starting point is usually below maintenance calories. Use this free calorie calculator result as an estimate and adjust based on weekly progress.

Maintenance calories are the estimated calories you need to keep your current weight stable at your current activity level.

Recalculate after meaningful weight, activity, or goal changes. For most users, every few weeks is enough.

Losing 1 kg per week often requires an average deficit close to 1,100 calories per day because 1 kg of fat is commonly estimated at about 7,700 calories. That pace is aggressive, so most people should use a calorie calculator for weight loss as a starting point and adjust based on recovery and hunger.

A calorie deficit means eating fewer calories than your body burns. A calorie deficit calculator estimates your maintenance calories first, then subtracts calories so your body uses stored energy over time.

Use a maintenance calories calculator with your age, sex, height, weight, and activity level. If your body weight stays stable for 2 to 3 weeks at that intake, you are likely close to maintenance.

For calories for muscle gain, many people start around maintenance plus 150 to 300 calories per day. Track body weight, strength, and measurements so the surplus stays controlled instead of excessive.

Yes. Daily calorie needs by age and activity often decrease with age because resting metabolism and total movement can decline, although resistance training and muscle mass can reduce that drop.

A 1,200-calorie diet may fit some smaller, less active adults, but it is often too low for men, active women, and most people who train regularly. Compare it with your maintenance calories and overall health needs before using it.

Calorie calculators are useful estimates, not exact measurements. Activity tracking errors, water retention, hormones, and untracked intake can change real-world results, so refine your target after 2 to 4 weeks of data.
