Frequently asked questions
- What is TDEE?
- Total Daily Energy Expenditure — the total calories you burn per day including exercise and daily activity. Use a TDEE calculator if you don't know your number.
- Can I also project a surplus (muscle gain)?
- Yes — enter an intake higher than your TDEE. The deficit will be negative, representing a surplus, and weight change will be positive.
