Frequently Asked Questions

Everything you need to know about intermittent fasting and the GoFasting app.

Intermittent fasting (IF) 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. Popular methods include the 16:8 method (16 hours fasting, 8 hours eating), 18:6, and 5:2 (eating normally 5 days, restricting calories 2 days). Research shows IF can boost metabolism, improve insulin sensitivity, and promote fat loss.
For most healthy adults, intermittent fasting is considered safe and well-studied. However, it's not recommended for pregnant or breastfeeding women, people with a history of eating disorders, or those with certain medical conditions. We always recommend consulting with your healthcare provider before starting any fasting regimen. GoFasting provides science-backed guidance to help you fast safely.
While many people can benefit from intermittent fasting, it may not be suitable for everyone. People under 18, pregnant or nursing mothers, and individuals with diabetes or other chronic conditions should consult a doctor first. GoFasting offers personalized plans that adapt to your health profile and goals, making it easier to find an approach that works for you.
During fasting periods, stay well hydrated with water, black coffee, or herbal tea. Avoid intense exercise during extended fasts. Listen to your body — if you feel dizzy or unwell, break your fast. When you do eat, focus on nutrient-dense whole foods. GoFasting provides helpful reminders for hydration and tips for each fasting stage to keep you on track.
GoFasting provides comprehensive tracking tools including a fasting timer with real-time stage indicators, weight and body measurement logging, calorie intake tracking, and weekly/monthly progress reports. You can visualize your fasting streaks, see trends in your weight data, and celebrate achievements with badges. All of this data helps you understand what's working and stay motivated.
