Intermittent Fasting Timer Description

What is Intermittent Fasting?

Intermittent fasting (IF) is an eating strategy that alternates between defined periods of fasting and eating. Unlike diets that restrict food types, IF focuses on timing.

• Promotes fat loss and metabolic efficiency
• Improves insulin sensitivity and cellular repair
• May enhance longevity and reduce inflammation

How the Calculator Works

This tool helps you determine your fasting progress based on inputted start time, fasting duration, and current time.

Formula:

Progress (%) = ((Current Time - Start Time) / Fasting Duration) × 100

Time calculations account for cross-midnight scenarios and durations longer than 24 hours.

Supported Fasting Protocols

• 16:8: Fast 16 hours, eat for 8
• 5:2: Normal eating 5 days, calorie restriction for 2
• Alternate-Day Fasting: Fast every other day
• OMAD (One Meal A Day): Eat within a 1-hour window

Edge Cases Handled

• Crossing Midnight: E.g., 8 PM start + 16 hours → ends at 12 PM next day
• Durations > 24 Hours: Long fasts like 36 or 48 hours fully supported
• Zero or Negative Durations: Validated to avoid errors or misinterpretation
• Start = Current Time: Displays 0% progress accurately
• Past End Time: Displays 100% with "Fasting Complete" status

Case Studies

Case Study 1: 16:8 Weight Loss

Sarah fasts from 6 PM to 10 AM daily. Over 3 months, she loses 12% body fat and improves glucose levels.

Case Study 2: Alternate-Day for Inflammation

James fasts every other day. After 6 weeks, his CRP levels drop 20%, suggesting lower systemic inflammation.
