Fastival is an intermittent fasting app which helps you start your intermittent fasting journey whether you are a novice or pro. We want to be your fasting companion, creating and motivating you towards your intermittent fasting goals. What is intermittent fasting? Intermittent fasting is an eating pattern where you cycle between periods of eating and fasting. There are many different types of intermittent fasting, such as the 16/8 or 5:2 methods. Numerous studies show that it can have powerful benefits for your body and brain. Why Fastival? Simple Fastival is designed to ensure ease of getting started. No onboarding, no user data collection.

No Subscription If you like Fastival, you can support us with a one time off payment to unlock all our premium offerings such as custom fasting, the full app customization basically. ----------- Why intermittent fasting? Lose weight When you fast, you give your body time to digest, burn excess energy and eventually additional fat, which leads to weight loss. However intermittent fasting is not a magic pill to weight loss. Intermittent fasting is a long term lifestyle, which can be a habit and weight loss is one of its outcomes. Just doing intermittent fasting for the sole purpose of weight loss might end up being a disappointment if this does not end up becoming a habit and just a temporary change just to lose weight. Health and vitality Intermittent fasting basically goes by the theory of giving your body enough rest between meals to recuperate and recover. During this time of extended fasting, there is no spike in blood sugar levels and your body is able to build better resistance to inflammation and other diseases. Long term fasting habits have been proven to improve overall health and vitality. Privacy Policy: https://www.nicebyte.io/privacy/ Terms of Use: https://www.nicebyte.io/terms/
