🔍 What is Intermittent Fasting? (A Quick Refresher)

Intermittent fasting (IF) is not a diet, but a structured eating pattern. It alternates between periods of eating and fasting. The most popular methods include:

• 16:8 – Fast for 16 hours, eat during 8 hours

• 5:2 – Eat normally for 5 days, restrict calories on 2 days

• OMAD (One Meal a Day) – A single meal within 1-2 hours

• Alternate-Day Fasting – Fasting every other day

Unlike calorie-counting diets, intermittent fasting focuses on when you eat, not just what you eat.

🧪 The Science Behind Intermittent Fasting in 2025

In 2025, research on intermittent fasting has grown significantly. New findings show:

🔬 1. Improved Metabolic Health

Studies continue to support that intermittent fasting improves:

• Insulin sensitivity

• Blood sugar regulation

• Cholesterol and triglyceride levels

• Fat metabolism

Short-term fasting helps trigger fat burning by lowering insulin levels and boosting norepinephrine.

🔬 2. Weight Loss

People still experience consistent weight loss through IF, especially when paired with a clean diet. A 2024 meta-analysis found that intermittent fasting participants lost an average of 7–11 pounds in 8 weeks.

🔬 3. Cellular Repair and Longevity

Fasting activates autophagy, a process where the body cleans out damaged cells, which may contribute to anti-aging and increased lifespan.

🔬 4. Mental Clarity and Focus

Reduced glucose fluctuations during fasting help many users report better cognitive performance and fewer energy crashes.
