Calorie Deficit for Weight Loss: How Many Calories Should You Actually Cut?

A calorie deficit means eating fewer calories than your body uses. It is the foundation of weight loss, but the size of the deficit matters for energy, hunger, training, and consistency.

Start With Maintenance Calories

Maintenance calories are the estimated calories needed to keep your weight stable. You need this number before choosing a deficit.

Use the Maintenance Calorie Calculator, Calorie Calculator, and BMR Calculator to estimate your baseline.

Common Deficit Ranges

A small deficit may be 200 to 300 calories per day. A moderate deficit may be 300 to 500 calories per day. Larger deficits can work for some people, but they are harder to sustain.

Use the Calorie Deficit Calculator to test different targets.

Do Not Cut Protein Too Low

Protein helps with fullness, recovery, and muscle maintenance. Cutting calories without planning protein can make dieting harder.

Use the Protein Calculator to set a practical daily target.

Adjust With Real Progress

Scale changes can be noisy because water, salt, stress, and digestion affect weight. Look at trends over several weeks before changing calories.

Use the Ideal Weight Calculator as a broad reference, not a strict rule.

Bottom Line

The best calorie deficit is one you can repeat. Start from maintenance, choose a moderate cut, keep protein strong, and adjust from real trend data.
