Question 1

What is TDEE?

Accepted Answer

TDEE stands for Total Daily Energy Expenditure. It represents the total number of calories you burn in a day, including your basal metabolic rate (BMR) and all physical activities. Your TDEE is the number of calories you need to maintain your current weight.

Question 2

How is TDEE calculated?

Accepted Answer

TDEE is calculated by multiplying your Basal Metabolic Rate (BMR) by an activity multiplier. We use the Mifflin-St Jeor equation to calculate BMR, then multiply it by your selected activity level (ranging from 1.2 for sedentary to 1.9 for very active).

Question 3

How do I use my TDEE for weight loss?

Accepted Answer

To lose weight, you need to eat fewer calories than your TDEE. A safe deficit is 300-500 calories per day for gradual weight loss (about 0.5-1 lb per week). To gain weight, eat 300-500 calories above your TDEE. To maintain weight, eat at your TDEE.

Question 4

How accurate is the TDEE calculator?

Accepted Answer

TDEE calculators provide estimates based on average population data. Individual variations in metabolism, muscle mass, genetics, and activity levels mean your actual TDEE may vary by ±10-20%. Use the calculated TDEE as a starting point and adjust based on your progress.

Question 5

What is the difference between BMR and TDEE?

Accepted Answer

BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest just to maintain basic life functions. TDEE includes your BMR plus all the calories burned through daily activities and exercise. TDEE is always higher than BMR unless you're completely bedridden.

Question 6

Should I recalculate my TDEE as I lose or gain weight?

Accepted Answer

Yes. Your TDEE changes as your weight changes. It's recommended to recalculate your TDEE every 5-10 lbs of weight change or every 4-6 weeks to ensure your calorie intake remains appropriate for your goals.

Question 7

Which activity level should I choose?

Accepted Answer

Choose based on your weekly exercise: Sedentary (little/no exercise), Light (1-3 days/week), Moderate (3-5 days/week), Active (6-7 days/week), or Very Active (intense daily training or physical job). Most people overestimate their activity level-when in doubt, choose the lower option.

Question 8

Does muscle mass affect TDEE?

Accepted Answer

Yes. Muscle tissue burns more calories at rest than fat tissue. People with more muscle mass have a higher BMR and TDEE. This is why strength training is beneficial for weight management-it increases your resting calorie burn.
