Short-term impact of a Western diet on the physiology of the peripheral olfactory system
2016
Current feeding behaviors contribute to the epidemic levels of obesity and diabetes observed in Europe and worldwide. Both the quantity and the quality of ingested food are incriminated. Together with other sensory modalities, olfaction is involved in the control of food intake. Olfactory cues can influence eating behaviors, yet the nutritional status and diet can also alter olfactory abilities. Patients with metabolic disorders present impaired olfactory sensitivity which could in turn worsen their eating behaviors.Here we examined the short-term impact of a Western diet enriched in fat and sugar (High Fat High Sugar, HFHS) on the anatomy and physiology of the olfactory epithelium of postn…
MATERNAL HIGH FAT DIET CONSUMPTION DURING PREGNANCY AND LACTATION: IMPACT ON INTESTINAL MORPHOLOGY AND FUNCTION IN PREWEANING OFFSPRING
2015
Different evidence supports an important role for maternal obesity in the development of childhood obesity and subsequent adult disease. This study is addressed to investigate if and to which extend maternal high fat feeding would induce compensatory and adaptative responses in gut predisposing to the eventual development of paediatric obesity. Adult female mice were divided into two groups fed with i) high fat (HF) diet and ii) standard chow (SC)diet, during pregnancy and lactation. HF mothers showed a significant weight gain, higher levels of blood glucose and an abnormal glucose tolerance compared to SC mother, indicating the establishment of metabolic syndrome. Then, offspring subdivide…
Perinatal Western Diet Consumption Leads to Profound Plasticity and GABAergic Phenotype Changes within Hypothalamus and Reward Pathway from Birth to …
2017
This article is part of the Research Topic Early Life Origins of Obesity and Type 2 Diabetes.; International audience; Perinatal maternal consumption of energy dense food increases the risk of obesity in children. This is associated with an overconsumption of palatable food that is consumed for its hedonic property. The underlying mechanism that links perinatal maternal diet and offspring preference for fat is still poorly understood. In this study, we aim at studying the influence of maternal high-fat/high-sugar diet feeding [western diet (WD)] during gestation and lactation on the reward pathways controlling feeding in the rat offspring from birth to sexual maturity. We performed a longit…
Glucagon-like peptide-2 analog and inflammatory state in obese mice
2020
Obesity is characterized by chronic low grade of systemic inflammation that develops in response to nutrient excess and plays a key role in the pathogenesis of insulin resistance. It is characterized by macrophage infiltration into adipose tissue (AT) and abnormal cytokine production. These factors damage the metabolic homeostasis leading to alteration in the insulin signaling in specific tissues and organs such as AT and liver. Thus, obese subjects develop over the time resistance to the cellular actions of insulin. Glucagon like peptide-2 (GLP-2) is an intestinal proglucagon-derived hormone released together with GLP1, in response to the passage of food by the distal small intestine. Once…
High-intensity interval training and moderate intensity training with exogenous adenosine counteract development of obesity in rats
2022
Objectives High-Intensity Interval Training (HIIT) and Moderate Intensity Training (MIT) can combat the obesity epidemic. However, studies comparing their effects on obesity show controversial findings regarding weight loss. Adenosine has emerged as a possible, novel therapeutic agent to treat obesity, but more preclinical studies on its efficacy are needed. Therefore, the objectives of this study were to compare the effects of HIIT and MIT on obesity, and further to determine the dose-dependent effects of adenosine on body weight. Equipment and methods We induced obesity in male Wistar rats with high-fat diet (HFD) and monitored development of obesity by comparing the weight to rats on nor…
