What Is Intermittent Fasting?

Intermittent fasting (IF) is a time-restricted eating pattern that alternates between periods of fasting and eating. Rather than restricting what you eat, IF focuses on when you eat. During fasting periods, the body shifts from using glucose for energy to burning stored fat, a metabolic state known as ketosis. This process triggers autophagy — the body's cellular cleanup mechanism — which removes damaged cells and promotes regeneration.

Research published in the journal Nutrients shows that intermittent fasting improves metabolic health markers including insulin sensitivity, blood pressure, and cholesterol levels (Li et al., 2023). The most popular methods include 16:8 (16 hours fasting, 8 hours eating), 18:6, and 5:2 (eating normally 5 days, restricting calories 2 days).

FastTrack is an iOS app that helps you practice intermittent fasting safely and effectively with a smart timer, progress analytics, and customizable fasting plans. All health data is stored locally on your device for complete privacy.

Frequently Asked Questions

What is intermittent fasting and how does it work? +
Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. It doesn't specify which foods to eat, but rather when you should eat them. Popular methods include 16:8 (fasting for 16 hours, eating within 8 hours) and 18:6. FastTrack helps you track these windows effortlessly.
Is FastTrack suitable for beginners? +
Absolutely! FastTrack is designed for everyone, from complete beginners to experienced fasters. We provide guided fasting plans, educational content, and gentle reminders to help you start your journey safely and effectively.
Can I customize my fasting schedule? +
Yes! While we offer popular preset schedules like 16:8 and 18:6, you can create completely custom fasting windows that fit your lifestyle. Adjust your schedule anytime to match your needs.
Is my health data private and secure? +
Your privacy is our top priority. All your health data is stored locally on your device and synced securely via iCloud. We never sell or share your personal information with third parties.
What can I drink while fasting? +
During your fasting window, you can drink water, black coffee, plain green tea, black tea, and herbal tea. Avoid adding sugar, milk, cream, or artificial sweeteners, as these can break your fast by triggering an insulin response. Staying well-hydrated is essential during fasting periods.
How much weight can I lose with intermittent fasting? +
Most people lose 2-10 pounds in their first week of intermittent fasting, though much of this is water weight. Sustainable fat loss typically ranges from 1-2 pounds per week. Results vary based on your fasting method, diet quality, activity level, and starting weight. FastTrack helps you track your progress over time for realistic expectations.
Is intermittent fasting safe for women? +
Yes, intermittent fasting can be safe and beneficial for women when practiced correctly. Women may benefit from starting with shorter fasting windows (14:10) and gradually increasing. Some women prefer crescendo fasting (fasting 2-3 non-consecutive days per week). Fasting is not recommended during pregnancy, breastfeeding, or for those with eating disorders. Always consult a healthcare provider first.
When does ketosis start during fasting? +
Your body typically begins entering ketosis between 12-24 hours of fasting, depending on factors like your activity level, diet, and metabolism. By 24-48 hours, most people are in full ketosis, where the body primarily burns fat for fuel. FastTrack shows you which metabolic stage you're in during your fast.
What are the health benefits of intermittent fasting? +
Research shows intermittent fasting can improve insulin sensitivity, reduce inflammation, promote autophagy (cellular repair), support heart health, enhance mental clarity, and aid weight loss. A 2023 study in the journal Nutrients found that intermittent fasting significantly improves metabolic health markers including blood pressure and cholesterol levels.
