The obesity pandemic has had a lasting impact on public health outcomes, thus effective and novel approaches to weight management are urgently needed. Intermittent fasting encompasses a wide variety of timetables for short-term food avoidance, such as "fasting every other day,""fasting for the whole day," and "time-restricted feeding," in which all of the day's food is ingested within a 6-hour window, resulting in 18 hours of fasting. Weight loss and metabolic health may be aided by intermittent fasting. These eating schedules are effective because they trigger the body to manufacture healthy ketones by intermittently inducing the conversion of fatty acids. Overall, the regimens result in reduced body mass index (BMI) and have been associated to better control of dyslipidemia and blood pressure. They cause a loss of body fat as an added benefit. While, more study is needed on longer-term effects, and this technique should be avoided in some health situations, intermittent fasting should be regarded as a realistic alternative for persons who have a record of unhealthy weight gain when adopting regular eating habits. Also, in some health circumstances, intermittent fasting is not recommended.
