Are you struggling to lose visceral fat no matter how hard you try? The answer may lie in how our bodies were designed.
For most of human history, people did not have constant access to food or sugar. Our bodies adapted to use stored energy during periods without food. When you eat frequently throughout the day, your body stays in a fed state and has fewer opportunities to shift toward fat metabolism.
This is why creating a regular fasting window can be powerful. A fasting period of at least 12 hours, including your sleep time, can help create a daily rhythm where your body has time away from food.
Fasting Manager makes that process simple, visible, and sustainable. By tracking your fasting window and helping you maintain regular measurement intervals for blood pressure and body weight, it keeps you accountable and motivated. Small, consistent habits - fasting a little longer, sleeping a little better, and measuring regularly - can help you understand your progress over time.
The app connects to Apple Health / HealthKit only to read user-authorized health data and display it in clear charts. It does not connect to, control, operate, or communicate with any external medical hardware.

Sleep

Steps

Heart Rate
Review heart rate data read from Apple Health in a weekly chart. Over time, changes in heart rate may help you better understand your activity, rest, and lifestyle patterns.
Fasting
Track your current fasting window, configure your eating schedule, and receive notifications to stay on track. Seeing how long you have been fasting, and how close you are to your target, makes it easier to stay committed.
Measurement Interval
Receive notifications to help you measure health-related data, such as blood pressure and body weight, at regular intervals. Regular measurements make it easier to maintain a habit of collecting useful data.
- Why It Helps -
You do not need to start with a strict diet. You do not need complicated food rules. Exercise is valuable, but building a steady fasting and measurement interval routine can be a practical first step. By combining fasting, sleep, movement, and regular data review, you can create a clearer picture of your daily habits.
This app does not tell you what to eat. It helps you manage when you eat, shows Apple Health data you authorize, helps you maintain your schedule, and keeps you accountable.
