The effects of time-restricted eating and weight loss on bone metabolism and health: a 6-month randomized controlled trial

Nicholas Edward Phillips, Alexandra Hemmer

Objective This study explored the impact of time-restricted eating (TRE) versus standard dietary advice (SDA) on bone health. Methods Adults with >= 1 component of metabolic syndrome were randomized to TRE (ad libitum eating within 12 hours) or SDA (food p ...

The Effects of Time-Restricted Eating versus Standard Dietary Advice on Weight, Metabolic Health and the Consumption of Processed Food: A Pragmatic Randomised Controlled Trial in Community-Based Adults

Felix Naef, Nicholas Edward Phillips

Weight loss is key to controlling the increasing prevalence of metabolic syndrome (MS) and its components, i.e., central obesity, hypertension, prediabetes and dyslipidaemia. The goals of our study were two-fold. First, we characterised the relationships b ...

Calorie restriction slows age-related microbiota changes in an Alzheimer's disease model in female mice

Alzheimer's disease (AD) affects an estimated 5.8 million Americans, and advanced age is the greatest risk factor. AD patients have altered intestinal microbiota. Accordingly, depleting intestinal microbiota in AD animal models reduces amyloid-beta (A beta ...

Neurochemical Modifications in the Hippocampus, Cortex and Hypothalamus of Mice Exposed to Long-Term High-Fat Diet

João Miguel das Neves Duarte, Ana Francisca Leal Silva Soares, Blanca Lizarbe Serra

Metabolic syndrome and diabetes impact brain function and metabolism. While it is well established that rodents exposed to diets rich in saturated fat develop brain dysfunction, contrasting results abound in the literature, likely as result of exposure to ...

Mitochondrial Post-translational Modifications and Metabolic Control: Sirtuins and Beyond

Carlos Canto Alvarez

Introduction: In order to maintain metabolic homeostasis, organisms adjust the capacity and efficiency of ATP generation to changes in energetic demand and supply. While the transcriptional control of mitochondrial biogenesis allows to adapt mitochondrial ...

Dietary restriction and Sirtuin 1 in metabolic health: connections and divergences

Carlos Canto Alvarez

Aging is the major risk factor for a constellation of multifactorial diseases, including insulin resistance, diabetes and cardiovascular complications. Dietary restriction has been shown to delay or prevent the manifestation of age-related health decline, ...

SIRT1 Gain of Function Does Not Mimic or Enhance the Adaptations to Intermittent Fasting

Carlos Canto Alvarez, Patrick Descombes, Sylviane Métairon

Caloric restriction (CR) has been shown to prevent the onset of insulin resistance and to delay age-related physiological decline in mammalian organisms. SIRT1, a NAD(+) -dependent deacetylase enzyme, has been suggested to mediate the adaptive responses to ...

An acetylation rheostat for the control of muscle energy homeostasis

Johan Auwerx, Keir Joe Menzies

In recent years, the role of acetylation has gained ground as an essential modulator of intermediary metabolism in skeletal muscle. Imbalance in energy homeostasis or chronic cellular stress, due to diet, aging, or disease, translate into alterations in th ...

The journey of resveratrol from yeast to human

Johan Auwerx

The natural polyphenolic compound resveratrol was first discovered in the 1940s. In the recent years, this compound received renewed interest as several findings implicated resveratrol as a potent SIRT1 activator capable of mimicking the effects of calorie ...

Calorie Restriction-like Effects of 30 Days of Resveratrol Supplementation on Energy Metabolism and Metabolic Profile in Obese Humans

Johan Auwerx, Richardus Houtkooper, Dongryeol Ryu

Resveratrol is a natural compound that affects energy metabolism and mitochondrial function and serves as a calorie restriction mimetic, at least in animal models of obesity. Here, we treated 11 healthy, obese men with placebo and 150 mg/day resveratrol (r ...

Calorie restriction: is AMPK a key sensor and effector?

Johan Auwerx, Carlos Canto Alvarez

Dietary restriction can extend life span in most organisms tested to date, suggesting that mechanisms sensing nutrient and energy availability might regulate longevity. The AMP-activated protein kinase (AMPK) has emerged as a key energy sensor with the abi ...

CREB and ChREBP oppositely regulate SIRT1 expression in response to energy availability

Johan Auwerx, Carlos Canto Alvarez, Chikage Mataki, Hiroyasu Yamamoto, Lilia Noriega Lopez, Jiujiu Yu

The nicotinamide adenine dinucleotide (NAD(+))-dependent deacetylase SIRT1 is a major metabolic regulator activated by energy stresses such as fasting or calorie restriction. SIRT1 activation during fasting not only relies on the increase in the NAD(+)/NAD ...

Caloric restriction, SIRT1 and longevity

Johan Auwerx, Carlos Canto Alvarez

More than 70 years after its initial report, caloric restriction stands strong as the most consistent non- pharmacological intervention increasing lifespan and protecting against metabolic disease. Among the different mechanisms by which caloric restrictio ...
