How to Calculate TDEE for Weight Loss and Healthy Living

What is TDEE Calculator?

A TDEE Calculator estimates your Total Daily Energy Expenditure, the number of calories you burn each day. It combines your Basal Metabolic Rate (BMR) and your daily physical activity, giving you a personalized calorie requirement.

Using your age, height, weight, gender, and activity level, this calculator helps you know how many calories you need to maintain, reduce, or gain weight. It simplifies nutrition planning by offering accurate, science-backed numbers instantly.

Formula Behind TDEE Calculator

First, the Basal Metabolic Rate (BMR) is calculated using the Mifflin-St Jeor formula. For men: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5; for women: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − 161. TDEE is then determined by multiplying BMR by an Activity Factor that reflects your lifestyle.

TDEE Conversion Table

Profile	BMR (kcal/day)	TDEE (kcal/day)	For 0.5kg Loss/Week
16y Male, 170cm, 65kg, Sedentary	1635	1962	1462
30y Female, 160cm, 60kg, Active	1314	2036	1536
40y Male, 175cm, 78kg, Very Active	1730	2983	2483

FAQs on Total Daily Energy Expenditure (TDEE) Calculator

1. What is TDEE and how is it different from BMR?

TDEE stands for Total Daily Energy Expenditure, representing the total calories your body burns in a day, including your Basal Metabolic Rate (BMR) and physical activity. BMR is the number of calories your body burns at rest to maintain basic functions. TDEE is always higher than BMR because it accounts for additional calories burned through exercise and daily activities. Understanding both is crucial for effective weight management.

2. How do I calculate my TDEE for weight loss using Vedantu's calculator?

Vedantu's TDEE calculator simplifies the process. Simply input your age, gender, height, weight, and activity level. The calculator will then compute your BMR and TDEE. To lose weight, aim for a calorie deficit by consuming fewer calories than your calculated TDEE. The calculator provides suggestions for a safe calorie deficit for weight loss.

3. What is a good calorie deficit for weight loss?

A safe and sustainable calorie deficit for weight loss is generally considered to be around 500 calories per day. This usually leads to a weight loss of about 0.5 kg per week. Larger deficits can be risky and may lead to nutrient deficiencies. Consult a nutritionist or healthcare professional for personalized guidance.

4. What are the different activity levels in the TDEE calculator?

Vedantu's TDEE calculator typically includes activity levels such as sedentary (little to no exercise), lightly active (light exercise 1-3 days/week), moderately active (moderate exercise 3-5 days/week), very active (hard exercise 6-7 days/week), and extra active (very strenuous exercise or a physically demanding job). Selecting the correct activity level ensures an accurate TDEE calculation.

5. How accurate is Vedantu's TDEE calculator?

Vedantu's TDEE calculator provides an estimate based on standard formulas. Individual results may vary due to factors not included in the calculation, such as genetics, metabolism, and individual variations in activity levels. It's a helpful tool for general guidance but shouldn't replace professional advice.

6. What is the Mifflin-St Jeor equation and how does it relate to TDEE?

The Mifflin-St Jeor equation is a widely used formula for estimating Basal Metabolic Rate (BMR). It takes into account age, gender, weight, and height. The BMR calculated using this equation is then multiplied by an activity factor to determine your TDEE.

7. Can I use the TDEE calculator to gain weight?

Yes, you can use the TDEE calculator to gain weight. Instead of aiming for a calorie deficit, you would consume more calories than your TDEE. This creates a calorie surplus, which is necessary for muscle gain or weight increase. Consult with a healthcare professional or nutritionist for a personalized plan.

8. What are some factors that affect TDEE besides those in the calculator?

Factors not accounted for in the calculator include genetics, underlying health conditions, medication use, and variations in daily activity beyond what's selected in the activity level. These factors can influence your individual calorie needs.

9. Is it important to track my calories alongside using the TDEE calculator?

While the TDEE calculator gives a valuable estimate, tracking your actual calorie intake can provide more precise information and help you achieve your weight management goals. Combining the calculator with a food diary or calorie-tracking app can increase the effectiveness of your strategy.

10. How often should I recalculate my TDEE?

Recalculate your TDEE if you experience significant changes in weight, height, activity levels, or age. Significant changes to your lifestyle or fitness routine necessitate recalculation to maintain accuracy.

11. What if my TDEE calculation seems inaccurate?

Remember, the TDEE calculator provides an estimate. If your results seem significantly off, consider consulting a healthcare professional or registered dietitian for personalized guidance. They can help determine your individual caloric needs based on your specific circumstances.
