Frequently Asked Questions
Maintenance calories are the number of calories you need to consume daily to maintain your current weight, assuming your activity level remains constant.
BMR (Basal Metabolic Rate) is calculated using the Mifflin-St Jeor equation: For men: 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) + 5; For women: 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) - 161.
Choose the activity level that best describes your typical weekly exercise. Sedentary means little or no exercise; Lightly active means 1-3 days per week; Moderately active means 3-5 days; Very active means 6-7 days; Extra active means very hard exercise daily.
