Principles of the Best Diet for Fast Fat Loss

1. Maintain a Calorie Deficit (Without Starving)

• Burn more calories than you consume.
• Aim for a deficit of 500–750 calories/day.
• Example: If maintenance is 2,500 calories, aim for 1,800–2,000.

2. Prioritize Protein

• Preserves muscle mass.
• Boosts metabolism (thermic effect).
• Reduces cravings.
• Sources: chicken, fish, eggs, Greek yogurt, tofu, lentils.

3. Choose Whole Carbs Over Refined

• Whole carbs = steady energy.
• Refined carbs = fat storage + insulin spikes.

• Swap examples:

  • White bread → whole-grain

  • Soda → sparkling water

4. Include Healthy Fats

• Support hormone regulation (testosterone, leptin).
• Improve satiety and brain health.
• Sources: avocado, nuts, olive oil, fatty fish.

5. Eat High-Fiber Foods
