Time-restricted eating and circadian rhythms: the biological clock is ticking

Critical Reviews in Food Science and Nutrition, Journal Year: 2020, Volume and Issue: 61(17), P. 2863 - 2875

Published: July 14, 2020

Meal timing may be a critical modulator of health outcomes due to complex interactions between circadian biology, nutrition and human metabolism. As such, approaches that aim align food consumption with endogenous rhythms are emerging in recent years. Time-restricted eating (TRE) consists limiting daily nutrient period 4 12 hours order extend the time spent fasted state. TRE can induce positive effects on individuals overweight obesity, including sustained weight loss, improvement sleep patterns, reduction blood pressure oxidative stress markers increased insulin sensitivity. However, it is not fully clear whether reduced energy intake, body or truncation window. In addition, null some populations parameters cardiometabolic have been documented. Some evidence indicates greater promotion via achieved if intake occurs earlier day. Despite promise this dietary strategy, performing at different times day health, as well safety efficacy approach impairments, need evaluated additional controlled long-term studies.

Complex physiology and clinical implications of time-restricted eating

Physiological Reviews, Journal Year: 2022, Volume and Issue: 102(4), P. 1991 - 2034

Published: July 14, 2022

Time-restricted eating (TRE) is a dietary intervention that limits food consumption to specific time window each day. The effect of TRE on body weight and physiological functions has been extensively studied in rodent models, which have shown considerable therapeutic effects important interactions among eating, circadian biology, metabolic homeostasis. In contrast, it difficult make firm conclusions regarding the people because heterogeneity results, regimens, study populations. this review, we 1) provide background history meal normal physiology fasting; 2) discuss interaction between molecular metabolism TRE; 3) integrate results preclinical clinical studies evaluated functions; 4) summarize other time-related interventions people; identify current gaps knowledge framework for future research directions.

Effects of Time-Restricted Feeding and Ramadan Fasting on Body Weight, Body Composition, Glucose Responses, and Insulin Resistance: A Systematic Review of Randomized Controlled Trials

Nutrients, Journal Year: 2022, Volume and Issue: 14(22), P. 4778 - 4778

Published: Nov. 11, 2022

Time-restricted feeding (TRF) and Ramadan fasting (RF) have been recently associated with several health outcomes. However, it is not yet clear if they are superior to existing treatments in terms of glucose metabolism, insulin action, weight loss. This review aims summarize the current data on effects these regimes body weight, composition, glycemia. An electronic search was conducted PUBMED SCOPUS databases up August 2022. Twenty-four records met inclusion criteria underwent a risk-of-bias assessment. The main outcomes were: (a) TRF may result moderate loss individuals overweight/obesity; when combined caloric restriction, >5% initial (b) 14 h be as effective 16 loss, (c) lead improved sensitivity glycemic responses/variability throughout day overweight/obesity. Concerning RF, only two studies were available thus, conclusions drawn. an nutritional approach for amelioration control more long-term, well-designed needed.

Timing of energy intake and the therapeutic potential of intermittent fasting and time-restricted eating in NAFLD

Gut, Journal Year: 2023, Volume and Issue: 72(8), P. 1607 - 1619

Non-alcoholic fatty liver disease (NAFLD) represents a major public health concern and is associated with substantial global burden of liver-related cardiovascular-related morbidity mortality. High total energy intake coupled unhealthy consumption ultra-processed foods saturated fats have long been regarded as dietary drivers NAFLD. However, there an accumulating body evidence demonstrating that the timing across day also important determinant individual risk for NAFLD metabolic conditions. This review summarises available observational epidemiological data describing associations between eating patterns disease, including negative effects irregular meal patterns, skipping breakfast night-time on health. We suggest these harmful behaviours deserve greater consideration in stratification management patients particularly 24-hour society continuous availability food up to 20% population now engaged shiftwork mistimed patterns. draw studies reporting liver-specific impact Ramadan, which unique real-world opportunity explore physiological fasting. By highlighting from preclinical pilot human studies, we present further biological rationale manipulating improve discuss how this may be mediated through restoration natural circadian rhythms. Lastly, comprehensively landscape trials intermittent fasting time-restricted offer look future about strategies benefit non-alcoholic steatohepatitis.

Achieving synchronization between the central and peripheral body clocks is essential for ensuring optimal metabolic function. Meal timing an emerging field of research that investigates influence eating patterns on our circadian rhythm, metabolism, overall health. This narrative review examines relationship meal timing, clock genes, hormones, It analyzes existing literature experimental data to explore connection mealtime, rhythms, processes. The available evidence highlights importance aligning mealtime with body’s natural rhythms promote health prevent disorders. Specifically, studies show consuming meals later in day associated elevated prevalence disorders, while early time-restricted eating, such as having breakfast earlier dinner, improves levels glucose blood substrate oxidation. Circadian including cortisol melatonin, interact mealtimes play vital roles regulating Cortisol, aligned dawn diurnal mammals, activates energy reserves, stimulates appetite, influences gene expression, synchronizes clocks. Consuming during periods melatonin levels, specifically night, has been correlated potential implications tolerance. Understanding mechanisms synchronization, genetics, interactions chronotype, sleep duration, hormonal changes, provides valuable insights optimizing dietary strategies timing. knowledge contributes improved well-being by rhythm.
