Fat loss is fundamentally simple: create a caloric deficit. But sustainable fat loss—losing fat while preserving muscle and maintaining energy—requires a strategic approach. This science-based guide gives you everything you need.
Step 1: Calculate Your Baseline
Before cutting calories, know your starting point. Use our BMR Calculator to find your basal metabolic rate, then our Calorie Calculator to determine your total daily energy expenditure (TDEE) based on activity level.
Step 2: Create a Moderate Deficit
Aim for a 300-500 calorie daily deficit—aggressive enough to see results, moderate enough to preserve muscle and energy. This typically produces 0.5-1kg fat loss per week. Larger deficits often backfire, causing muscle loss and metabolic adaptation.
Step 3: Prioritize Protein
During a deficit, protein is even more critical. Aim for 2.2-2.5g per kg bodyweight to preserve muscle mass. Spread intake across 4-5 meals. For complete protein strategies, see our protein masterclass.
Step 4: Maintain Strength Training
Resistance training signals your body to preserve muscle while in a deficit. This is non-negotiable for body composition. Continue lifting heavy with our strength-focused workouts and track progress using our One Rep Max Calculator.
Step 5: Consider Timing Strategies
Some find intermittent fasting helpful for managing hunger and simplifying meal planning during fat loss. It's a tool, not magic—calories still matter most.
Step 6: Optimize Recovery
Sleep deprivation increases hunger hormones and muscle breakdown. Learn why sleep is your secret weapon for fat loss. Aim for 7-9 hours nightly.
Step 7: Be Patient and Consistent
Sustainable fat loss takes time. Expect fluctuations—water weight, hormones, and digestion affect the scale daily. Focus on weekly trends, not daily numbers.
