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.

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.

Background: The potential positive interaction between intermittent fasting (IF) and brain-derived neurotrophic factor (BDNF) on cognitive function has been widely discussed. This systematic review tried to assess the efficacy of interventions with different IF regimens BDNF levels their association functions in humans. Interventions forms such as caloric restriction (CR), alternate-day (ADF), time-restricted eating (TRE), Ramadan model (RIF) were targeted. Methods: A was conducted for experimental observational studies healthy people patients diseases published EMBASE, Scopus, PubMed, Google Scholar databases from January 2000 December 2023.
