Fast and Low app for iPhone and iPad

Fast and Low: An Engineer’s Approach to Health and Wellness offers a unique strategy for making and managing lifestyle changes toward better health.
Often people struggle to stick with a healthy lifestyle change for several reasons, such as inertia, habit, environment, lack of results, and sometimes just because the change is too difficult or painful.
While the app is about managing diet, intermittent fasting, exercise, sleep, and meditation—all well-known cornerstones of good health—it distills the key principles of each factor and suggests actions that can help you easily incorporate them into your life.
Based on scientific research (we have published a book on this subject) the app helps users to convert their health goals into measurable numbers that can be tracked easily and then use these metrics to find the optimal path toward those goals.
Everyone is different, and where health is concerned, there is no single and complete formula that can work for everyone.
Based on metrics—concrete means of measuring progress and quantifying success—the app uses a scientific experimentation framework in which users can make informed decisions about their health and lifestyle changes.
The app has easy to use interfaces for managing a low-carb diet and in equal detail covers intermittent fasting and all well known fasting protocols. Several other key health metrics and how to track them can be added in custom metrics with regard to exercise, sleep, and meditation.
