Before you start thinking of fasting as a miracle cure, Jain notes that it’s important to keep in mind that most relevant studies have been done on animals and have not been able to be replicated consistently in people. That being said, there is some limited evidence that certain types of fasting may have a positive effect. Many types of fasting have been studied, from completely refraining from food for prolonged periods of time to only eating a certain number of calories per day or restricting food intake to a certain number of hours per day.
