What is the purpose of a TDEE calculator?

Your TDEE can be used to estimate the number of calories you need to consume daily to maintain your current weight. Consuming fewer calories than your estimated TDEE can result in weight loss. Consuming more calories than your estimated TDEE can be useful for building lean muscle mass.

How is TDEE calculated?

We calculate your TDEE by first establishing your BMR (basal metabolic rate) using the Mifflin-St. Jeor equation. This requires your gender, age, height, and weight. Then, our calculator multiplies your BMR by your activity level to get your TDEE.

• BMR × Activity Level = TDEE

What is BMR?

BMR stands for basal metabolic rate. This is an estimate of the calories you burn without any physical activity. To put it simply, BMR is the amount of fuel your engine (body) burns while idling (resting). If you were resting in bed all day, this is about the number of calories your body will use.

Why do you need my activity level?

Your activity level is essential for calculating your TDEE. As your physical activity increases, so do the number of calories you burn. TDEE is the total of all the energy you use each day, including physical activity (walking, running, sports, manual labor, etc.). To understand how much energy your body burns without factoring in physical activity, check out our BMR (basal metabolic rate) calculator here.

How can this free TDEE calculator help me with my Healthy Keto plan?

While counting calories is not the main objective of the Healthy Keto diet, knowing how much energy you use each day can help you create a plan to meet your weight loss goals. If you can’t seem to lose weight after becoming fully keto-adapted, you may need to reduce your calorie intake by lowering your fat, carb, and protein consumption. Dr. Berg’s free TDEE calculator helps you understand how much energy your body needs each day when adjusting for physical activity.
