  6. Metabolic Effects of Intermittent Fasting

    Ruth E. Patterson, Dorothy D. Sears · 2017 · Annual Review of Nutrition · 821 citations

    The objective of this review is to provide an overview of intermittent fasting regimens, summarize the evidence on the health benefits of intermittent fasting, and discuss physiological mechanisms by which intermittent fasting might lead to improved health outcomes. A MEDLINE search was performed using PubMed and the terms "intermittent fasting," "fasting," "time-restricted feeding," and "food timing." Modified fasting regimens appear to promote weight loss and may improve metabolic health. Several lines of evidence also support the hypothesis that eating patterns that reduce or eliminate nighttime eating and prolong nightly fasting intervals may result in sustained improvements in human hea

  7. Flipping the Metabolic Switch: Understanding and Applying the Health Benefits of Fasting

    Stephen D. Anton, Keelin Moehl, William T. Donahoo, et al. · 2017 · Obesity · 777 citations

    OBJECTIVE: Intermittent fasting (IF) is a term used to describe a variety of eating patterns in which no or few calories are consumed for time periods that can range from 12 hours to several days, on a recurring basis. This review is focused on the physiological responses of major organ systems, including the musculoskeletal system, to the onset of the metabolic switch: the point of negative energy balance at which liver glycogen stores are depleted and fatty acids are mobilized (typically beyond 12 hours after cessation of food intake). RESULTS AND CONCLUSIONS: Emerging findings suggest that the metabolic switch from glucose to fatty acid-derived ketones represents an evolutionarily conserv

    V. Carvajal, A. Marín, Daniela Gihardo, et al. · 2023 · Revista medica de Chile · 399 citations

    Intermittent fasting (IF) has gained increasing scientific and general attention. Most studied forms of IF include alternate-day fasting, modified alternate-day fasting, and time-restricted eating (TRE). Several cardiometabolic effects of IF have been described in animal models and, to a lesser extent, in humans. This review analyzes the impact of IF on weight loss, glucose metabolism, blood pressure, and lipid profile in humans. A literature search was conducted in the Pubmed/Medline, Scopus, and Google Scholar databases. Controlled observational or interventional studies in humans, published between January 2000 and June 2021, were included. Studies comparing IF versus religious fasting we

  9. Intermittent Fasting and Metabolic Health

    I. Vasim, C. Majeed, M. DeBoer · 2022 · Nutrients · 284 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

    Krista A Varady, Sofia Cienfuegos, Mark Ezpeleta, et al. · 2021 · Annual Review of Nutrition · 187 citations

    This review aims to summarize the effects of intermittent fasting on markers of cardiometabolic health in humans. All forms of fasting reviewed here-alternate-day fasting (ADF), the 5:2 diet, and time-restricted eating (TRE)-produced mild to moderate weight loss (1-8% from baseline) and consistent reductions in energy intake (10-30% from baseline). These regimens may benefit cardiometabolic health by decreasing blood pressure, insulin resistance, and oxidative stress. Low-density lipoprotein cholesterol and triglyceride levels are also lowered, but findings are variable. Other health benefits, such as improved appetite regulation and favorable changes in the diversity of the gut microbiome,

  11. 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 · 86 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

  12. Intermittent Fasting Regulates Metabolic Homeostasis and Improves Cardiovascular Health

    Rawan Diab, Lina Dimachkie, Omar Zein, et al. · 2024 · Cell Biochemistry and Biophysics · 27 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

  16. 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

  24. 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
