Frequently Asked Questions

What formula is used to calculate calorie needs?
The Mifflin-St Jeor equation calculates your Basal Metabolic Rate (BMR), which is then multiplied by an activity factor to give your Total Daily Energy Expenditure (TDEE).
What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day including all activity. Eating at TDEE maintains your current weight.
How many calories should I cut to lose weight?
A 500 kcal/day deficit generally leads to approximately 1 lb (0.45 kg) of weight loss per week. A 250 kcal deficit leads to about 0.5 lb/week. Always consult a healthcare professional before making significant dietary changes.
