Question 1

Are your fitness calculators accurate?

Accepted Answer

Our calculators use scientifically validated formulas and equations (like Mifflin-St Jeor for BMR, Navy Method for body fat, etc.). While they provide good estimates, individual results may vary due to genetics, metabolism, and other factors.

Question 2

Do I need to create an account to use the calculators?

Accepted Answer

No! All our calculators are free to use without an account. However, creating a free account allows you to save your calculation history, track progress over time, and access your results from any device.

Question 3

What's the difference between BMR and TDEE?

Accepted Answer

BMR (Basal Metabolic Rate) is the calories you burn at complete rest just to maintain basic bodily functions. TDEE (Total Daily Energy Expenditure) is BMR plus all the calories you burn through daily activities and exercise. TDEE is always higher than BMR and is what you should use for diet planning.

Question 4

How much protein do I really need?

Accepted Answer

For general health: 0.8g per kg of bodyweight. For muscle building: 1.6-2.2g per kg (0.7-1g per lb). For fat loss while preserving muscle: 1.8-2.4g per kg (0.8-1.1g per lb). Active individuals and older adults benefit from the higher end of these ranges.

Question 5

How often should I recalculate my macros or calories?

Accepted Answer

Recalculate every 2-4 weeks if you're actively losing or gaining weight, or whenever your activity level changes significantly. As your body composition changes, your calorie and macro needs will adjust accordingly.
