Week-by-Week Progress & Tips

How Calorie Deficit Calculation Works

Weight Loss Science

1 kg of body fat = 7,700 calories. To lose 10kg, you need a total deficit of 77,000 calories over 20 weeks.

Daily deficit needed: 550 calories | Weekly deficit: 3,850 calories

TDEE & Deficit Calculation

Your TDEE (Total Daily Energy Expenditure): 2,662 calories. Target calories: 2,112 = TDEE - 550 deficit.

Safe minimum: 1500 calories/day | Your target: 2,112 calories/day

High Protein Approach

Protein: 160g (2g per kg body weight) to preserve muscle mass during weight loss. Remaining calories split between carbs and essential fats.

Macros: 160g protein, 224g carbs, 64g fats = 2,112 calories

Exercise Component

Recommended approach: 70% deficit from diet, 30% from exercise (165 cal/day from activity).

Exercise plan: 150 min cardio/week + 3 strength sessions
