Impact of intermittent energy restriction on anthropometric outcomes and intermediate disease markers in patients with overweight and obesity: system…
2020
This systematic review aims to investigate the effects of intermittent energy restriction (IER) on anthropometric outcomes and intermediate disease markers. A systematic literature search was conducted in three electronic databases. Randomized controlled trials (RCTs) were included if the intervention lasted ≥12 weeks and IER was compared with either continuous energy restriction (CER) or a usual diet. Random-effects meta-analysis was performed for eight outcomes. Certainty of evidence was assessed using GRADE. Seventeen RCTs with 1328 participants were included. IER in comparison to a usual diet may reduce body weight (mean difference [MD]: −4.83 kg, 95%-CI: −5.46, −4.21; n = 6 RCTs), wais…
COVID Obesity: A One-Year Narrative Review
2021
On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO). This study focuses on a narrative review about the illness during the first year of the pandemic in relation to obesity. Databases were used to search studies published up to 8 December 2020. In total, 4430 articles and other scientific literature were found, and 24 articles were included in this one-year narrative review. The mean BMI value of severe COVID-19 patients ranged from 24.5 to 33.4 kg/m2, versus 2 for non-severe patients. Articles using the terms obesity or overweight without indicating the BMI value in these patients were common, but this is not useful, as the a…
Perception oro-sensorielle des lipides alimentaires et obésité
2016
International audience; The gustation is a dynamic system able to rapid physiological adaptations in response to on-going environmental changes that characterize our feed (rhythm, quality, quantity). Based on the modulation of taste sensitivity thresholds, this homeostatic system contributes to build the feeding behavior by driving the food choices. Therefore, a dysfunction of this regulatory system might impact on dietary habits and thus, ultimately, on health. Consistent with this assumption, recent data report that a diet-induced obesity is associated both with a dysfunction of the oral fat detection system and a preferential consumption of fat-rich diets in rats and mice. In humans, a s…

Non-conscious effect of food odors on children's food choices varies by weight status
2017
Open access original research (article number UNSP 16); OBJECTIVE: Food cues are omnipresent in the daily environment and may influence eating behavior even non-consciously. An increased reactivity to food cues, such as food odors, has been shown to be correlated with obesity in children. The objective of this study is to investigate whether the non-conscious influence of food odors on children's food choices varies by their weight status. METHODS: Seventy-four children, of whom 29 were obese, took part in this study. The children performed a food choice intention task presented as a computer game in which 30 pairs of food images (a fatty-sweet food picture vs. a fruit picture) successively…
The corticotrophin-releasing factor/urocortin system regulates white fat browning in mice through paracrine mechanisms.
2015
Objectives:\ud The corticotrophin-releasing factor (CRF)/urocortin system is expressed in the adipose tissue of mammals, but its functional role in this tissue remains unknown.\ud \ud Methods:\ud Pharmacological manipulation of the activity of CRF receptors, CRF1 and CRF2, was performed in 3T3L1 white pre-adipocytes and T37i brown pre-adipocytes during in vitro differentiation. The expression of genes of the CRF/urocortin system and of markers of white and brown adipocytes was evaluated along with mitochondrial biogenesis and cellular oxygen consumption. Metabolic evaluation of corticosterone-deficient or supplemented Crhr1-null (Crhr1−/−) mice and their wild-type controls was performed alo…

Are gut hormones responsible for the decrease of appetitive behaviour for sweet and fatty foods after gastric bypass surgery?
2013
WOS: 000321389200211; International audience; Introduction: Gastric bypass surgery (RYGB) decreases preference for sweet and fatty foods, but the underlying mechanism is not known. This study aimed to investigate the role of the exaggerated satiety gut hormone release on appetitive reward of sweet and fatty taste after RYGB. Method: 13 patients that have undergone previous RYGB surgery (>6 months) and 13 normal weight controls participated in a double-blind placebo-controlled trial comparing the effect of subcutaneous injections of somatostatin analogue (octreotide) which blocks satiety gut hormone responses, and saline (control) on the appetitive reward value of sweet-fat candies. Appetiti…
Intermittent Fasting and the Possible Benefits in Obesity, Diabetes, and Multiple Sclerosis: A Systematic Review of Randomized Clinical Trials
2021
Intermittent fasting has become popular in recent years and is controversially presented as a possible therapeutic adjunct. A bibliographic review of the literature on intermittent fasting and obesity, diabetes, and multiple sclerosis was carried out. The scientific quality of the methodology and the results obtained were evaluated in pairs. Intermittent fasting has beneficial effects on the lipid profile, and it is associated with weight loss and a modification of the distribution of abdominal fat in people with obesity and type 2 diabetes as well as an improvement in the control of glycemic levels. In patients with multiple sclerosis, the data available are too scarce to draw any firm con…
