Frequently Asked Questions
How many calories should I eat per day to lose weight?
Eat 500 calories below your TDEE for ~1 lb/week loss. For example, if your TDEE is 2,200 calories, eat 1,700/day. Avoid going below 1,200 calories (women) or 1,500 (men) without medical supervision.
What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is calories burned at complete rest — just to keep you alive. TDEE (Total Daily Energy Expenditure) adds your activity level on top. You should eat at your TDEE to maintain weight.
Which calorie formula does this calculator use?
The Mifflin-St Jeor equation, which is considered the most accurate for most people: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5 (men) or −161 (women). The Harris-Benedict formula is also available.
How accurate are calorie calculators?
TDEE estimates can be off by 10–20% due to individual metabolic variation. Use the result as a starting point, track your actual weight change over 2–3 weeks, then adjust intake by 100–200 calories if needed.
Do I need to count calories to lose weight?
Not necessarily, but tracking helps. Awareness of intake is the strongest predictor of dietary adherence. Many people lose weight without formal counting by focusing on food quality, portion control, and satiety signals.
