Physiology of intermittent fasting

Abstract

There is a continuing need for new and efficient weight-control methods due to the long-lasting consequences of the obesity pandemic on public health outcomes. Intermittent fasting, which comprises a variety of timing regimens for temporary food avoidance, such as alternate-day fasting, alternative full-day fasting patterns, and time-restricted feeding, is one strategy for enhancing weight and metabolic outcomes. The irregular conversion of fatty acids into ketones encouraged by these diets has positive metabolic consequences. The programmes generally support weight loss and have been associated with reduced blood pressure and dyslipidaemia. Intermittent fasting should be taken into consideration as a possibility for people who have a tendency to gain weight unhealthily using conventional eating habits, even if more research is needed on the long-term implications and this strategy should be avoided in particular health conditions.
