1. Understanding Belly Fat: Why It’s Hard to Lose
There are two types of belly fat:
1) Subcutaneous Fat
Fat under the skin—soft and visible.
2) Visceral Fat (the dangerous one)
Fat stored around organs—linked to:
• diabetes
• heart disease
• hormonal imbalance
Why belly fat is stubborn:
• High cortisol (stress hormone)
• High insulin levels
• Low muscle mass
• Poor sleep
• Processed foods
• Aging (especially after 30)
Losing it requires a multi-factor approach, not just cutting calories.

⭐ 2. The Science of Fast Belly Fat Loss (2025 Research)
New studies show belly fat responds fastest to:
A) High-Protein Diets (Harvard Study)
Eating protein reduces:
• appetite
• cravings
• ghrelin (hunger hormone)
B) 12–15 Minute HIIT Workouts
Short bursts burn more belly fat than 45 minutes jogging.
C) Improved Sleep Routine
Poor sleep increases cortisol → stores fat.
D) Stable Blood Sugar
Avoiding sugar helps insulin stay low → fat burning increases.
