What Is Intermittent Fasting?
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It’s not a diet—it’s about when you eat, not what you eat.
Top 6 Science-Backed Benefits
1️⃣ Weight Loss & Fat Burning
Fasting increases fat oxidation and reduces insulin levels.
Study: IF helped participants lose 3-8% of body weight in 3-24 weeks.
2️⃣ Improves Insulin Sensitivity (Lowers Diabetes Risk)
Fasting reduces blood sugar levels by 20-31% in prediabetics.
3️⃣ Boosts Brain Function
Increases BDNF, a protein linked to better memory and learning.
4️⃣ May Extend Lifespan
Animal studies show IF can increase lifespan by 18-30%.
5️⃣ Reduces Inflammation & Oxidative Stress
Linked to lower risk of heart disease, Alzheimer’s, and cancer.
6️⃣ Supports Cellular Repair (Autophagy)
Fasting triggers autophagy, where cells remove damaged components.
