Calorie deficit calculator
Your daily target to lose weight.
To lose weight you eat a little less than you burn — a calorie deficit. Tell us about you and pick a pace, and we’ll suggest a sensible daily calorie target.
Used to estimate your metabolism — the formula needs it.
A slower, steadier pace is usually easier to stick to.
Fill in your details and pick a pace to see your target.
Going too low can backfire, so we won’t suggest dropping below roughly 1,200 calories a day for women or 1,500 for men. This is general guidance, not medical advice — before starting any weight-loss plan, speak to a qualified clinician.
