Effects of Intermittent Fasting on Weight Management

Abstract:

Intermittent Fasting (IF) is a lifestyle approach characterized by alternating eating and fasting periods that has recently become popular because of its potential health benefits. This study tested the association between IF and body mass index (BMI) and outlined how each of the IF methods could affect weight, health, and metabolism. Popular examples of IF include 16:8, 5:2, alternate-day fasting, and time-restricted eating. IF has been associated with weight loss, improves insulin sensitivity, decreases inflammation, and improves autophagy and cellular repair. BMI is one of the most widely accepted methods for determining weight status and associated health risks. BMI is often used in clinical and research settings. BMI is useful to assess populations, but it does not directly evaluate the regional distribution of fat in individuals. Obesity defined by elevated BMI is a worldwide concern, especially in developing countries that are going through changes in lifestyle patterns. This article also discusses the anatomical mechanisms of IF including the transitions from glucose as the energy source to using fat, hormonal regulation, and the critical role of the liver in glucose and lipid metabolism. Research and outcomes from randomized controlled trials and studies suggest that IF can be favorable to cardiometabolic markers and lessen the rate of chronic disease incidence. If done properly, IF has a variety of potential advantages, it may not be appropriate for everyone, especially with older adults and vulnerable populations. Particularly for IF, individual plans with medical supervision are suggested. Overall, IF can be a beneficial way to manage BMI and improve metabolic health.
