What is a healthy BMI range?

According to the WHO and CDC, a healthy BMI for adults is 18.5–24.9. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese. BMI is a screening tool, not a diagnostic measure of body fatness.

How many calories do I need per day?

Average adults need 1,600–2,400 calories per day for women and 2,000–3,000 for men, depending on age, height, weight, and activity level. Use the TDEE calculator for a personalized estimate based on the Mifflin-St Jeor equation.

What is BMR and how is it calculated?

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest. The Mifflin-St Jeor formula: Men: 10×weight(kg) + 6.25×height(cm) − 5×age + 5. Women: 10×weight(kg) + 6.25×height(cm) − 5×age − 161.

What is a healthy body fat percentage?

For men, healthy body fat is 8–19%; for women, 21–33%. Athletes typically have 6–13% (men) or 14–20% (women). Above 25% (men) or 32% (women) is considered obese by the American Council on Exercise.

How much protein should I eat per day?

The RDA is 0.8g per kg of body weight for sedentary adults. For muscle building, 1.6–2.2g/kg is evidence-based (International Society of Sports Nutrition). For weight loss, higher protein (1.2–1.6g/kg) helps preserve lean mass.

Results are estimates not medical advice

These tools provide general wellness estimates based on population-level formulas. Individual results may differ due to body composition, medical history, age, fitness level, and factors these inputs cannot capture. Some calculators may show results that do not reflect your personal health situation. Do not use these results to diagnose, treat, or make clinical decisions. Always consult a qualified healthcare provider, registered dietitian, or certified fitness professional before making significant changes to your diet, exercise, or health plan.
