How is my calorie target set?

Surplus works out how many calories you use in a day from your weight, height, age and sex, multiplies that by your activity level, then adds a surplus for the pace you picked:

• Gain weight slowly: 300 kcal a day
• Gain weight steadily: 500 kcal a day
• Gain weight quickly: 700 kcal a day

Change any of these and the target updates. Your weights, weekly goal and activity level are in Profile › Goals, and your height, sex and date of birth are in Profile › Settings › Profile.
