What is a Calorie Deficit?
A calorie deficit occurs when you consume fewer calories than your body burns. Our calorie deficit calculator helps you determine the optimal deficit for safe, sustainable weight loss. Use this calorie deficit calculator to plan your nutrition strategy.
Energy Balance
Weight loss requires burning more calories than you consume. A 500 calorie daily deficit leads to ~0.5kg (1lb) weekly loss.
Sustainable Loss
Safe weight loss is 0.25-1kg (0.5-2lbs) per week. Faster loss risks muscle loss and metabolic slowdown.
Muscle Preservation
High protein intake (1.6-2.2g/kg) and resistance training help preserve muscle during calorie deficit.

Understanding Deficit Levels
Our calorie deficit calculator offers three deficit levels. Use this calorie deficit calculator to find your ideal pace:
🐢 Conservative (0.25kg/0.5lbs per week)
Best for: Beginners, those with little weight to lose, or maintaining muscle mass during cutting.
Deficit: ~250-300 calories/day. Easiest to maintain, minimal hunger, best muscle preservation.
⚖️ Moderate (0.5kg/1lb per week)
Best for: Most people. Balanced approach with good results and manageable adherence.
Deficit: ~500 calories/day. Recommended by most health professionals as sustainable and effective.
🚀 Aggressive (0.75kg/1.5lbs per week)
Best for: Those with significant weight to lose, under medical supervision, or with deadlines.
Deficit: ~750 calories/day. Requires discipline, may cause more hunger, higher risk of muscle loss.
Tips for Calorie Deficit Success
Track Consistently
Use apps like MyFitnessPal to track calories accurately. Weigh food for precision, especially calorie-dense items like oils and nuts.
Prioritize Protein
Aim for 1.6-2.2g protein per kg body weight. Protein increases satiety and preserves muscle during weight loss.
Lift Weights
Resistance training 3-4x per week signals your body to preserve muscle. Essential during calorie deficit.
Sleep Well
Aim for 7-9 hours nightly. Poor sleep increases hunger hormones and makes deficit adherence harder.
