Understanding BMR & TDEE for Sustainable Weight Management

Whether your goal is losing body fat, building lean muscle mass, or maintaining athletic performance, all energy balance starts with two metrics: Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).

1. What is BMR?

Your BMR is the baseline number of calories your body burns at rest to keep vital organs (brain, heart, lungs, liver) functioning. You can estimate your exact resting calories with our BMR Calculator or check your overall BMI Calculator category.

2. Calculating TDEE & Calorie Targets

TDEE multiplies your BMR by an Activity Factor (ranging from 1.2 for sedentary lifestyle to 1.9 for intense daily exercise). To lose weight sustainably, aim for a 300 to 500 calorie deficit below TDEE.
