Frequently Asked Questions

How many calories should I eat to lose weight?

For safe weight loss, aim for a 500-750 calorie daily deficit, which equals about 1-1.5 lbs per week. Do not go below 1200 (women) or 1500 (men) calories without medical supervision.

What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total calories you burn in a day, including exercise and daily activities. Your maintenance calories equal your TDEE - eat less to lose weight, more to gain.

How accurate are calorie calculators?

Calorie calculators provide estimates based on proven formulas like Mifflin-St Jeor. Individual metabolism varies, so use the results as a starting point and adjust based on your actual progress over 2-4 weeks.
