⚖️ Understanding Your Daily Calorie Balance

Daily calorie balance is the relationship between calories consumed and calories burned. A negative balance (deficit) leads to weight loss, while a positive balance (surplus) supports muscle gain. Apple Watch tracks your calorie expenditure, and FitnessView displays your burn data to help you manage your calorie balance.

Key Ranges: Deficit of 500 cal/day ≈ 1 lb/week loss | Surplus of 300 cal/day for muscle gain | Maintenance: intake = expenditure
