Questions

What is TDEE?

Total daily energy expenditure is the calories you burn in a day, including exercise. Eating about that amount keeps your weight steady.

How accurate is it?

It is an estimate. Real needs vary with muscle, genetics and health. Use it as a starting point and adjust from how your weight changes over a few weeks.

Is it safe to eat much less?

Very low calorie diets are not usually recommended without medical advice. Talk to a doctor or dietitian before you make big changes.
