Come Funziona il Deficit Calorico
In breve: Il deficit calorico si ottiene consumando meno calorie di quelle bruciate. 1 kg di grasso corporeo equivale a circa 7.700 kcal.
Weight loss is fundamentally governed by the First Law of Thermodynamics: consuming fewer calories than your Total Daily Energy Expenditure (TDEE) forces your body to oxidize stored adipose tissue (body fat) and glycogen to satisfy energetic demands.
Calorie Deficit Magnitudes, Fat Loss Rates & Lean Mass Preservation
Comparing deficit magnitudes to balance fat oxidation speed against metabolic adaptation and hormonal health:
| Deficit Strategy | Daily Calorie Cut | Weekly Weight Loss | Muscle Retention & Sustainability |
|---|---|---|---|
| Mild Deficit (10–15%) | 250 – 350 kcal/day | 0.5 lbs / 0.25 kg | Optimal (99%+ muscle preserved; zero diet fatigue) |
| Moderate Deficit (20–25%) | 500 – 750 kcal/day | 1.0 – 1.5 lbs / 0.5 – 0.7 kg | Gold Standard (High fat loss with strength retention) |
| Aggressive Deficit (30–35%) | 1,000+ kcal/day | 2.0+ lbs / 1.0 kg | Moderate risk of muscle catabolism and metabolic slowdown |
Regole per un Dimagrimento Sicuro
Mantieni un deficit di 300–500 kcal e fai allenamento contro resistenza.
