Please enter positive height, weight, and age parameters to calculate your BMR.
*Calculated using 2000 daily maintenance calories. Gram formulas assume Protein & Carbs possess 4 calories per gram, and Fats possess 9 calories per gram.
Energy balance is the fundamental physical law governing weight gain, weight loss, and athletic performance. The human body expends a specific volume of energy daily, measured in calories, to sustain basic life support and physical kinetic activity.
Calorie intake is the fuel that powers your body's vital functions and daily physical activities. Balancing energy input (food consumed) and energy output (metabolism and movement) is the key to maintaining, losing, or gaining body weight.
To lose weight sustainably without harming metabolism, aim for a conservative caloric deficit of 300 to 500 calories below your calculated TDEE.
