Good to know
- BMR is the energy your body uses at rest. Multiplying it by an activity factor gives the calories you burn in a typical day.
- Start with the lowest activity level that fits you. Most people overestimate how active they are.
- Weigh yourself over two to three weeks and adjust by 100–200 kcal if your weight is not moving as planned.
- Pregnancy, illness, medication and medical conditions change calorie needs. Ask a doctor or dietitian for personal advice.
