Intermittent Fasting: Are You Making These 3 Beginner Mistakes?

What Is Intermittent Fasting?

Intermittent fasting (IF) isn't a diet — it's an eating pattern. Rather than changing what you eat, you change when you eat.

The Science

During fasting, your body undergoes several changes:

• Insulin levels drop, facilitating fat burning
• Human growth hormone increases by up to 500%
• Cellular repair processes activate (autophagy)
• Gene expression changes beneficially

Popular Methods

16:8 Method (Most Popular)

Fast for 16 hours, eat within an 8-hour window.

Example: Eat between 12pm-8pm, fast from 8pm-12pm.

5:2 Method

Eat normally 5 days per week, consume 500-600 calories on 2 non-consecutive days.

Eat-Stop-Eat

One or two 24-hour fasts per week. More advanced.

Benefits

• Weight loss (3-8% body weight over 3-24 weeks)
• Improved insulin sensitivity
• Reduced inflammation
• Better brain function
• Potential longevity benefits

Getting Started Safely

Week 1: 12:12

Fast for 12 hours overnight (8pm-8am). Most people already nearly do this.

Week 2: 14:10

Extend the fast slightly. Skip the late-night snack.

Week 3: 16:8

The sweet spot for most people. Black coffee and water are fine during the fast.

Who Should Avoid IF

• Pregnant or breastfeeding women
• People with eating disorder history
• Those on diabetes medication (without medical supervision)
• Under-18s

Tips for Success

• Stay hydrated
• Start gradually
• Don't overeat during eating windows
• Listen to your body
