Frequently Asked Questions About Calorie Calculation

What is BMR (Basal Metabolic Rate)?

BMR is the number of calories your body needs to maintain basic life functions like breathing, circulation, and cell production while at rest. It accounts for about 60-75% of your total daily calorie expenditure.

What is TDEE (Total Daily Energy Expenditure)?

TDEE is your total daily calorie needs, including BMR plus calories burned through physical activity and daily movement. This is the number you should use to determine your calorie intake for weight management.

How many calories should I eat to lose weight?

To lose weight, create a calorie deficit by eating 300-500 calories less than your TDEE. A safe weight loss rate is 0.5-1 kg (1-2 pounds) per week. Never eat below 1200 calories for women or 1500 calories for men without medical supervision.

How many calories should I eat to gain weight?

To gain weight, eat 300-500 calories more than your TDEE. Focus on nutrient-dense foods and combine with strength training for healthy weight gain. Aim for 0.25-0.5 kg (0.5-1 pound) per week.

Which activity level should I choose?

Sedentary (1.2): Little or no exercise, desk job
Lightly Active (1.375): Light exercise 1-3 days/week
Moderately Active (1.55): Moderate exercise 3-5 days/week
Very Active (1.725): Hard exercise 6-7 days/week
Extremely Active (1.9): Very hard exercise, physical job

How accurate is this calorie calculator?

Our calculator uses the scientifically validated Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating calorie needs. However, individual results may vary based on factors like muscle mass, genetics, and metabolism.

Should I recalculate my calories as I lose weight?

Yes, recalculate your calorie needs every 5-10 pounds of weight change, as your BMR decreases with weight loss. This ensures you maintain an appropriate calorie deficit for continued progress.
