Calories/Day (TDEE)
* Extreme weight loss targets should be monitored by a professional. Caloric needs depend on metabolism, body composition, and exact daily activity level.

Calculating Your Maintenance (TDEE) and Deficit
To lose, gain, or maintain weight, your body relies on the laws of thermodynamics. Our platform utilizes the scientifically validated Mifflin-St Jeor equation to find your Basal Metabolic Rate (BMR)—the baseline energy your body burns at absolute rest—and multiplies it by your activity level to establish your Total Daily Energy Expenditure (TDEE).
If your goal is shedding fat, our calorie deficit calculator simplifies the process by computing safe, sustainable pacing structures relative to your TDEE:
The Energy Balance Formula
TDEE (Maintenance) = BMR × Activity MultiplierThe Deficit Formula for Fat Loss
Daily Caloric Target = TDEE - Target Deficit (e.g., 500 kcal)For example, if your daily maintenance baseline is 2,300 kcal, subtracting a standard 500 kcal daily deficit establishes a target of 1,800 kcal. Over a week, this cumulative energy deficit of 3,500 kcal corresponds to roughly 0.5 kg (1 lb) of fat loss.

Nutrition Tip
"Consistency over intensity. Small, sustainable calorie deficits are statistically more likely to result in long-term weight maintenance than crash diets."
