Our Weight Loss Calculator is a comprehensive tool designed to help healthcare professionals and wellness businesses provide accurate, personalized weight management solutions for their clients. This advanced calculator combines multiple essential metrics, including BMI (Body Mass Index), BMR (Basal Metabolic Rate), and TDEE (Total Daily Energy Expenditure), to generate customized weight loss plans based on individual parameters. Users can input key data points such as age, gender, height, weight, and activity level to receive detailed recommendations for calorie intake and macronutrient distribution. The calculator supports healthcare providers in developing sustainable, evidence-based weight management strategies that align with their clients’ specific needs and goals. Whether you’re a nutritionist, fitness professional, or wellness coach, this tool streamlines the process of creating personalized weight loss plans while enhancing the credibility of your services.
The calculator converts your details into a daily-calorie target using Mifflin-St Jeor BMR and an activity factor. A 35-year-old, 85 kg, 178 cm male who is lightly active gets ≈2,467 kcal TDEE; to lose 7 kg in 12 weeks he’ll aim for ≈1,825 kcal/day—a 642 kcal deficit. Losing 0.5–1 kg per week is the range “associated with sustainable success” (CDC, 2023).
