Understanding Your Metrics
Your Basal Metabolic Rate (BMR) is the number of calories your body needs at rest. This forms the basis for calculating your daily calorie needs.
Step 2: Activity & Goals
About Calorie Goals
For weight loss, aim for a 500 calorie daily deficit to lose approximately 0.5 kg per week. For weight gain, aim for a 500 calorie surplus.

Calorie Formula
BMR Formula (Mifflin-St Jeor Equation)
For men: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(y) + 5
For women: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(y) – 161
TDEE = BMR × Activity Multiplier
