  1. Intermittent Fasting and Metabolic Health

    I. Vasim, C. Majeed, M. DeBoer · 2022 · Nutrients · 259 citations

    Given the ongoing strain that the obesity epidemic has placed on public health outcomes, new and effective approaches to weight control are needed. One approach to improving weight and metabolic outcomes is intermittent fasting, which consists of multiple different timing schedules for temporary food avoidance, including alternate-day fasting, other similar full-day fasting patterns, and time-restricted feeding (where the day’s food is consumed over a 6-h period, allowing for 18 h of fasting). These feeding schedules have favorable metabolic effects by intermittently inducing the metabolism of fatty acids to ketones. The regimens overall lead to a decrease in weight and have been linked to i

  2. The role of intermittent fasting and meal timing in weight management and metabolic health

    Iain Templeman, Javier T. Gonzalez, Dylan Thompson, et al. · 2019 · Proceedings of the Nutrition Society · 71 citations

    Obesity remains a major public health concern and intermittent fasting is a popular strategy for weight loss, which may present independent health benefits. However, the number of diet books advising how fasting can be incorporated into our daily lives is several orders of magnitude greater than the number of trials examining whether fasting should be encouraged at all. This review will consider the state of current understanding regarding various forms of intermittent fasting (e.g. 5:2, time-restricted feeding and alternate-day fasting). The efficacy of these temporally defined approaches appears broadly equivalent to that of standard daily energy restriction, although many of these models

  3. Intermittent Fasting Regulates Metabolic Homeostasis and Improves Cardiovascular Health

    Rawan Diab, Lina Dimachkie, Omar Zein, et al. · 2024 · Cell Biochemistry and Biophysics · 26 citations

    Obesity is a leading cause of morbidity and mortality globally. While the prevalence of obesity has been increasing, the incidence of its related complications including dyslipidemia and cardiovascular disease (CVD) has also been rising. Recent research has focused on modalities aimed at reducing obesity. Several modalities have been suggested including behavioral and dietary changes, medications, and bariatric surgery. These modalities differ in their effectiveness and invasiveness, with dietary changes gaining more interest due to their minimal risks compared to other modalities. Specifically, intermittent fasting (IF) has been gaining interest in the past decade. IF is characterized by cy

  8. Effects of Intermittent Fasting on Weight Loss and Cardiometabolic Health

    Rümeysa GERBOĞA, Cansu BEKAR · 2023 · Current Perspectives on Health Sciences · 2 citations

    Intermittent fasting is a cyclical way of eating that is formed by the succession of eating and fasting period. It includes a long period of fasting, such as 16-48 hours, in which individuals receive little or no energy, and a normal eating period. The most commonly applied methods are alternate day fasting (ADF), time-restricted feeding (TRF) the 5:2 diet and Ramadan fasting. It has been reported that these diet models can be an alternative to continuous energy restriction in the medical nutrition treatment of obesity and are effective in weight loss. Intermittent fasting can have positive effects on reducing the risk of cardiovascular diseases and improving symptoms by causing reductions i

  16. Unlocking Health: The Rise of Intermittent Fasting for Weight Loss and Metabolic Wellness

    Somenath Ghosh, J. Abraham, E. Lakshmi · 2024 · International Journal of Pharma and Bio Sciences

    Intermittent fasting (IF), encompassing methods like alternate-day fasting (ADF), the 5:2 diet, and time-restricted feeding (TRF), has garnered significant attention for its potential health benefits. TRF involves consuming food within an 8-hour daily window, leading to metabolic shifts and adaptive responses in the brain and nervous system. IF often results in reduced calorie intake, similar to calorie restriction (CR) regimens in laboratory studies. IF also promotes autophagy, reducing inflammation and oxidative stress and lowering the health risk of chronic diseases like cancer and neurodegenerative disorders. IF may enhance sleep quality and duration by aligning eating patterns with circ

  17. The Impact of Intermittent Fasting on Metabolic Health and Chronic Disease Prevention: A Comprehensive Review

    Arisa Tantirasmee · 2024 · International Journal of Current Science Research and Review

    Intermittent fasting has gained attention as a dietary approach focusing on the timing of eating rather than the specific foods being consumed. Unlike the traditional calorie restriction, intermittent fasting involves alternating periods of fasting and eating. Several prevalent forms of IF exist, each with unique fasting durations and eating windows. For instance, the 16/8 method restricts food intake to an 8-hour window each day, followed by 16 hours of fasting. The 5:2 diet involves eating regular meals for five days a week and significantly reducing calorie intake to 500-600 calories on the remaining two non-consecutive days. Another popular method, Eat-Stop-Eat, includes one or two 24-ho

  20. INTERMITTENT FASTING AND CHRONONUTRITION: SYNERGISTIC APPROACHES FOR METABOLIC HEALTH

    Andressa dos Reis Gonçalves Mariani · 2023 · Revista Sistemática

    Intermittent fasting (IF) and chrononutrition are emerging dietary strategies that align eating patterns with human circadian rhythms to improve metabolic health. While intermittent fasting emphasizes extended periods without caloric intake, chrononutrition focuses on the timing of food consumption relative to biological clocks. Both approaches have been associated with improvements in insulin sensitivity, lipid metabolism, and weight management. Evidence suggests that meal timing plays a critical role in regulating circadian physiology, influencing hormone secretion, glucose metabolism, and energy expenditure. Integrating principles of IF and chrononutrition may provide synergistic benefits
