365-Day Transformation & Calorie Calculator
Calculate your scientifically grounded metabolic rate (BMR), daily caloric target (TDEE), and realistic time required to reach your dream physique.
1. Your Physical Metrics
Maintenance TDEE: 2446 kcal (BMR: 1779 kcal)
At a sustainable rate of 0.5 kg / week, reaching your goal of 74 kg will take approximately 16 weeks (~112 days) of consistency.
The Science Behind This Calculator
Our calculator employs the validated Mifflin-St Jeor equation, widely regarded by the Academy of Nutrition and Dietetics as the most accurate standard for predicting resting metabolic rate (BMR). By multiplying your BMR by an activity multiplier, we determine your Total Daily Energy Expenditure (TDEE).
Fat loss targets are calculated with a moderate 500 kcal daily deficit (producing ~0.5kg of tissue loss per week), safeguarding lean muscle tissue and preventing metabolic adaptation. Muscle building targets incorporate a modest 250-300 kcal surplus to optimize muscle protein synthesis (MPS) without excessive adipose accumulation.
