How Weight Loss Calculation Works - Medical Methodology
Our Weight Loss Calculation System uses WHO & FDA-verified medical formulas to provide accurate timeline projections and health optimization insights:
Core Metabolic Formula: BMR Calculation using Mifflin-St Jeor Equation: Men: 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5 | Women: 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161
Activity Level Adjustment: Sedentary: ×1.2, Light Activity: ×1.375, Moderate: ×1.55, Very Active: ×1.725, Extra Active: ×1.9. These factors account for daily energy expenditure beyond basal metabolic rate.
Calorie Deficit Planning: Daily calorie target = TDEE - Calorie Deficit. Sustainable deficits range from 250-1000 calories daily, with 500 calories being the standard recommendation for 0.5 kg weekly weight loss.
Timeline Projection: 7700 calorie deficit = 1 kg weight loss. Timeline = (Weight to Lose × 7700) ÷ Daily Calorie Deficit. This provides exact week-by-week projections.
Healthy Rate Limits: Our calculator enforces WHO guidelines of 0.5-1 kg per week maximum safe weight loss rate, preventing dangerous rapid weight loss recommendations.
Gender & Age Considerations: Women's calculations include hormonal factor adjustments, especially for menopause considerations. Age-related metabolic decline is factored into all projections.
Weight Loss Management Strategies
- Track consistently - regular weight monitoring helps identify trends and adjust strategies as needed
- Focus on sustainable deficits - aim for 250-500 calorie deficits for long-term success rather than extreme restrictions
- Prioritize protein intake - adequate protein preserves muscle mass during weight loss and promotes satiety
- Combine cardio and strength training - cardio burns calories while strength training preserves metabolism-boosting muscle
- Manage sleep and stress - poor sleep and high cortisol levels can hinder weight loss efforts
- Stay hydrated - adequate water intake supports metabolism and can reduce mistaken hunger signals
- Practice mindful eating - eat without distractions, chew thoroughly, and listen to hunger/fullness cues
- Plan for maintenance - develop strategies for weight maintenance before reaching your goal weight
- Be patient with plateaus - weight loss plateaus are normal; focus on non-scale victories and consistency
- Consult healthcare providers - for personalized guidance, especially with medical conditions or medications affecting weight
