How Do We Calculate Your Calories?
Our calculator uses the Mifflin-St Jeor Equation, which is widely considered the most accurate standard formula for calculating Basal Metabolic Rate (BMR) by health and nutrition professionals. Once your BMR is calculated, we multiply it by your chosen Activity Level multiplier to determine your TDEE.
Weight Loss Rules of Thumb
- 1 Pound of Fat is roughly equivalent to 3,500 calories.
- To lose 1 lb per week: You need a daily deficit of 500 calories (3,500 ÷ 7).
- To lose 2 lbs per week: You need a daily deficit of 1,000 calories. (Note: Men should generally not consume fewer than 1,500 calories a day, and women no fewer than 1,200 calories a day without medical supervision).
