How Many Calories Should I Eat?
The number of calories you should eat depends on your body size, age, sex, activity level, and goal. A person who works a physical job and trains regularly usually needs more energy than someone with a desk job and little exercise. That is why a calorie calculator asks for personal details before creating an estimate.
The most useful calorie number is usually your maintenance calories. Maintenance calories are the amount of food energy that keeps your body weight roughly stable over time. If you eat more than maintenance consistently, your weight may increase. If you eat less than maintenance consistently, your weight may decrease.
Calories for weight loss
For weight loss, many people start with a moderate deficit instead of cutting calories aggressively. A smaller deficit can be easier to follow, support better workouts, and reduce the chances of quitting. If your weight is not changing after several weeks, adjust slowly.
Calories for muscle gain
For muscle gain, eating slightly above maintenance can help support training and recovery. More calories do not automatically mean more muscle. A large surplus may lead to extra fat gain, so many people start with a modest increase.
How to adjust your target
- Track your average body weight for two to three weeks.
- Look at the trend, not a single weigh-in.
- If weight loss is too fast or energy is low, increase calories slightly.
- If weight is not moving and fat loss is the goal, reduce calories slightly.
