Answers to common questions about intermittent fasting and the Fast & Fit app.
Everything you wanted to know about Fast & Fit.
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It doesn't prescribe which foods to eat, but rather when you should eat them. Common methods include the 16:8 method, 5:2 diet, and eat-stop-eat.
Intermittent fasting may be suitable for many healthy adults, but it is not right for everyone. If you are pregnant or breastfeeding, under 18, have a history of disordered eating, diabetes, low blood pressure, take medication affected by meals, or have a medical condition, speak with a healthcare professional before starting.
Water, black coffee, plain tea, and sparkling water are generally allowed during a fast. These beverages have minimal or no calories and won't break your fast.
Progress varies by person and depends on sleep, nutrition, activity, medical history, and consistency. Some users first notice better routine awareness or fewer late-night snacks. Weight changes are not guaranteed, so focus on sustainable habits and track trends over time.
The 12:12 or 14:10 protocol is ideal for beginners as it involves fasting overnight and skipping late-night snacks. Once comfortable, you can progress to the popular 16:8 protocol.
Muscle maintenance depends on total nutrition, protein intake, resistance training, sleep, and the size of any calorie deficit. If maintaining muscle is important to you, pair fasting with balanced meals and appropriate training, and consider guidance from a qualified professional.
Many people tolerate light or moderate activity during a fasting window, but responses vary. Start gently, hydrate, stop if you feel dizzy or unwell, and schedule harder workouts near your eating window if that feels better. Ask a clinician if you have a medical condition.
No. Fast&Fit is a personal wellness tracking tool, not a medical device or a substitute for professional medical advice. Use the app to track habits and schedules, and consult a healthcare professional for personal medical guidance.
