How to estimate the calories you need

  1. Choose your sex and type your age, height and weight.
  2. Pick how active you are on a normal week.

You get the calories that keep your weight steady, plus gentle loss and gain targets.

How it works

Pockit uses the Mifflin-St Jeor equation to estimate the energy your body uses at rest, then multiplies it by an activity factor. It is an estimate; your weight over a few weeks is the real guide.

How fast should I lose weight?

About 0.25 to 0.5 kg a week is a common, sustainable pace. Pockit does not suggest intakes below 1,200 kcal for women or 1,500 kcal for men. For a health condition, pregnancy or anyone under 18, talk to a doctor or dietitian.
