Acute inflammatory and metabolic effect of high fructose intake in normal-weight women: A randomized, double-masked, crossover trial.

Objectives: We aimed to evaluate the acute effect of a fructose-rich single meal on metabolic and inflammatory biomarkers RESEARCH METHODS AND PROCEDURES: This single-center, double-masked, randomized crossover trial recruited females aged 20 to 47 with a normal body mass index and was conducted at Hospital das Clínicas (Belo Horizonte, MG, Brazil). Participants received a standardized meal with either sucrose, glucose, or a fructose overload. Blood samples were collected after overnight fasting (baseline) and at 30, 60, 120, and 240 minutes postprandial.

Blunted inflammatory response is associated with a lower response to a weight loss dietary intervention in liver recipients.

Background & Aims: Obesity is associated with chronic low-grade inflammation, and adipose tissue inflammation is required for fatty tissue remodeling. Interestingly, immunosuppressed patients, as liver transplant recipients, often experience excessive weight gain. We investigated how liver recipients' inflammatory response affects body weight loss induced by dietary treatment.

Role of IL-18 in adipose tissue remodeling and metabolic dysfunction.

Background/objectives: Proinflammatory cytokines are increased in obese adipose tissue, including inflammasome key masters. Conversely, IL-18 protects against obesity and metabolic dysfunction. We focused on the IL-18 effect in controlling adipose tissue remodeling and metabolism.

Protective Effect of Bovine Milk Extracellular Vesicles on Alveolar Bone Loss.

Scope: Bovine milk extracellular vesicles (MEVs) have demonstrated therapeutic potential in regulating bone cell activity. However, the outcome of their use on alveolar bone loss has not yet been demonstrated.

Methods And Results: This study evaluates the effect of oral administration of MEVs on ovariectomized (OVX) mice.

Acute exercise modulates the inflammatory response in adipose tissue in both lean and obese mice.

Objectives: Acute physical exercise acts as a metabolic stressor, promoting activation of the immune system, and this response could be relevant in the adipose tissue remodeling process. In addition, some cytokines have important functions in lipolysis. Because chronic exercise improves obesity-related metabolic and inflammatory dysfunction, herein we investigated the effect of acute exercise on the inflammatory responses in the adipose tissues of lean and obese mice.

Effect of high-refined carbohydrate diet on intestinal integrity.

Objectives: One of the leading causes of obesity is the consumption of excess nutrients. Obesity is characterized by adipose tissue expansion, chronic low-grade inflammation, and metabolic alterations. Although consumption of a high-fat diet has been demonstrated to be a diet-induced obesity model associated with gut disorders, the same effect is not well explored in a mild-obesity model induced by high-refined carbohydrate (HC) diet intake.

The Intervention of Diet on Energy Metabolism.

Food intake patterns determine changes in energy expenditure due to their influence on body size and composition (percentage of fat, bone, and muscle), which can modulate signaling pathways that optimize energy consumption [...

Eosinophils protect from metabolic alterations triggered by obesity.

Background: Eosinophils are generally related to helminth infections or allergies. Their association with metabolic alterations and adipose tissue (AT) remodeling has been demonstrated mainly in animal models of obesity. However, their physiological role in driving metabolic features has not yet been well described.

Metabolic and behavioral effects of time-restricted eating in women with overweight or obesity: Preliminary findings from a randomized study.

Objectives: The aim of this study was to evaluate the effects of 8 wk of time-restricted eating (TRE) along with a caloric restriction on metabolic profile, metabolic rate, symptoms of mood, and eating disorders and weight loss in women with overweight or obesity.

Methods: Women age 18 to 59 y with a body mass index of ≥25 kg/m were enrolled in this parallel-arm, randomized, clinical trial. Participants were randomly allocated into two groups (8-h TRE or non-TRE group) using a 2:1 allocation strategy.

Dysbiotic oral microbiota contributes to alveolar bone loss associated with obesity in mice.

Introduction: Periodontal diseases (PD) are inflammatory conditions that affect the teeth supporting tissues. Increased body fat tissues may contribute to activation of the systemic inflammatory response, leading to comorbidities. Some studies have shown that individuals with obesity present higher incidence of PD than eutrophics.

Contribution of RAS, ROS and COX-1-derived prostanoids to the contractile profile of perivascular adipose tissue in cafeteria diet-induced obesity.

Aims: Obesity can lead to the loss of the anticontractile properties of perivascular adipose tissue (PVAT). Given that cafeteria (CAF) diet reflects the variety of highly calorie and easily accessible foods in Western societies, contributing to obesity and metabolic disorders, we sought to investigate the impact of CAF diet on PVAT vasoactive profile and the involvement of renin-angiotensin system, oxidative stress, and cyclooxygenase pathway.

Main Methods: Male Balb/c mice received standard or CAF diet for 4 weeks.

Protective Effect of Virgin Coconut Oil on Osteopenia Induced by High Refined Carbohydrate-Containing Diet in Mice.

Background: Obesity leads to chronic low-grade inflammation, promoting detrimental effects on bone. The consumption of virgin coconut oil (VCO) is associated with benefits related to meta-inflammation. We evaluated the effect of VCO supplementation on osteopenia promoted by diet-induced obesity in mice.

Ginger supplementation does not increase energy expenditure in female adults.

Unlabelled: Food components with thermogenic properties are promising antiobesity agents. Ginger (Zingiber officinale Rosc.) bioactive compounds have a capsaicin-like vanillyl portion, which has been attributed to thermogenic effect in previous experimental studies.

Cannabidiol ameliorates the anxiogenic and compulsive-like behaviors induced by chronic consumption of a high-carbohydrate diet in male mice.

The excessive consumption of ultra-processed foods and the development of obesity has been associated with several comorbidities, including psychiatric disorders. Excess fat tissue promotes a low-intensity inflammatory state, mainly in the white tissue, which is essential in developing metabolic alterations and influences brain homeostasis. In this scenario, Cannabidiol (CBD), a compound from Cannabis sativa, has presented anxiolytic and anti-inflammatory effects in murine models.

Gluten-Free Diet Reduces Diet Quality and Increases Inflammatory Potential in Non-Celiac Healthy Women.

Aim: Gluten-free diets (GFDs) have gained popularity in the general population. Nonetheless, controlled studies are necessary before decisions can be made to promote GFDs. We aimed to evaluate the effects of gluten intake on body weight, body composition, and resting energy expenditure and observe the changes in nutrient intake caused by GFDs.

PAF signaling plays a role in obesity-induced adipose tissue remodeling.

Background/objectives: Platelet-activating factor receptor (PAFR) activation controls adipose tissue (AT) expansion in animal models. Our objective was twofold: (i) to check whether PAFR signaling is involved in human obesity and (ii) investigate the PAF pathway role in hematopoietic or non-hematopoietic cells to control adipocyte size.

Materials/subjects And Methods: Clinical parameters and adipose tissue gene expression were evaluated in subjects with obesity.

Thirty days of combined consumption of a high-fat diet and fructose-rich beverages promotes insulin resistance and modulates inflammatory response and histomorphometry parameters of liver, pancreas, and adipose tissue in Wistar rats.

Objective: The aim of this study was to verify the effects of consumption of a high-fat diet (HFD) combined with fructose-rich beverages (FRT) in promoting metabolic and physiologic changes associated with insulin resistance.

Methods: Thirty-two male Wistar rats (250 ± 10 g) were randomly allocated into four groups (n = 8) that received either a standard diet (CON), HFD, FRT, or HFD + FRT for 30 d. Insulin sensitivity and glucose tolerance were evaluated using the insulin tolerance test (ITT) and oral glucose tolerance test (OGTT).

High-Carbohydrate Diet Enhanced the Anticontractile Effect of Perivascular Adipose Tissue Through Activation of Renin-Angiotensin System.

The perivascular adipose tissue (PVAT) is an active endocrine organ responsible for release several substances that influence on vascular tone. Increasing evidence suggest that hyperactivation of the local renin-angiotensin system (RAS) in the PVAT plays a pivotal role in the pathogenesis of cardiometabolic diseases. However, the local RAS contribution to the PVAT control of vascular tone during obesity is still not clear.

Acute effects of dry extract of ginger on energy expenditure in eutrophic women: A randomized clinical trial.

Background & Aims: The thermic effect of food (TEF) is one of the components of total energy expenditure (TEE). Some bioactive compounds present in food could be useful to increase TEE. In this context, ginger has been extensively used as a thermogenic food despite no clear effect has been demonstrated yet.

Mindfulness-based program to support lifestyle modification and weight loss in infertile women: randomized controlled trial.

Objective: We evaluated the short-term effects of a mindfulness-based program (MBP) on weight loss through lifestyle modification in infertile women who were overweight or obese.

Methods: The participants were randomly assigned to 8 consecutive weekly sessions of MBP plus diet or diet alone. Both groups received a customized dietary plan.

Altered Serum Levels of Renin-Angiotensin System Markers in Migraine.

Objective: To compare the serum levels of renin-angiotensin system (RAS) components between patients with migraine and healthy controls, and to evaluate whether these levels are associated with migraine severity. We hypothesized that migraine would be associated with the activation of the inflammatory arm of the RAS, possibly leading to increased levels of angiotensin (Ang) II.

Background: Recent studies have proposed the use of drugs that interfere with RAS, a hormonal system primarily implicated in blood pressure regulation, as a prophylactic strategy for migraine.
