Filter by:Dietary calcium seems to act on glycemic control, favoring the prevention and treatment of type 2 diabetes mellitus (DM2). It is possible that calcium modulates gut microbiota and increase the integrity of the intestinal mucosa. This study aims to evaluate the effects of dietary calcium supplementation in permeability and intestinal microbiota in overweight type 2 diabetics. This is a single-blind, randomized, placebo-controlled, crossover study. Patients (n=20) with low habitual calcium intake will be allocated in control group (CONTROL) or test group (DAIRY). Hypocaloric diets (restriction of 500 kcal / day) will be prescribed containing 800 mg of calcium from dietary sources / day. During intervention period, a beverage (shake) (CONTROL - without the addition of calcium sources or DAIRY - 700 mg of calcium as milk powder) will be ingested in the laboratory. Food intake, body composition (total body fat and fat free mass) and anthropometric measures (waist circumference, waist-hip ratio, waist-height, neck circumference and sagittal abdominal diameter) will be evaluated at baseline and at the 6th and 12th weeks. Physical activity level, gut permeability, gut microbiota, and biochemical parameters (parathyroid hormone, 25-dihydroxy vitamin D, calcium, fasting glucose, fasting insulin, fructosamine, hemoglobin, HbA1c, uric acid, triglycerides, cholesterol total and partial, lipopolysaccharide, inflammatory markers) will be evaluated at baseline and after 12 weeks. The statistical analysis will be performed with the use of SPSS software (SPSS Inc., Chicago, IL, 2008, version 17.0). Parametric or non-parametric tests will be applied, according to the distribution of variables (level of statistical significance of 5%).
The major goal of this project is to evaluate an innovative approach to obesity. This study will determine if behavioral treatment can be improved by 1) implementing a primary focus on PA following initial weight loss treatment, and 2) using a novel, acceptance-based approach to the promotion of PA.
The purpose of this study is to determine whether inclusion of almonds in a weight loss regimen will augment the rate of weight loss, promote a greater fat mass/fat-free mass ratio of weight loss, improve blood pressure and ameliorate the post-lunch dip in cognitive function.
The purpose of this study is to investigate the effect of canagliflozin, a medication approved by the FDA for the treatment of type 2 diabetes, on body weight and metabolism in people with type 2 diabetes who are overweight or obese. Canagliflozin lowers glucose levels in the blood by making the kidneys excrete, rather than absorb, glucose. Canagliflozin is also often associated with weight loss. The study population will generally be type 2 diabetics, ages 18-75 years old, who are overweight or obese.
This study is a double-blind randomized, placebo-controlled, parallel-group, 12 week study performed in 2 centres in Sweden to assess the effect of Omega-3 carboxylic acids and fenofibrate on liver fat measured with magnetic resonance imaging (MRI) in patients with over-weight and hypertriglyceridemia.
The purpose of this study is to determine whether oral supplementation with one form of arginine improves vascular endothelial function in healthy subjects with risk factors associated with the metabolic syndrome
The purpose of this study is to compare the metabolic fate of two oral forms of L-Arginine in healthy subjects featuring metabolic syndrome related risk factors
This study aims at evaluating the consequences of a 3 weeks high protein diet on the large intestine ecosystem (microbiota, metabolites and gene expression in rectal mucosa). Those parameters will be analysed with technics including OMICs methods. After a run-in period, 42 volunteers will receive either soy or milk protein or maltodextrin as a placebo control. This trial is double blind randomized placebo-controlled paralleled design (3 arms). Longitudinal sampling will allow the comparison of parameters during the study.
The potential health effects of high intake of lean or fatty fish will be investigated in overweight or obese adults. Participants consume 750g/week of fillets of fish for 8 weeks. Hypothesis: High intake of fatty or lean fish will beneficially affect glucose regulation and the immune system.
U.S. Army Medical Research & Materiel Command Telemedicine and Advanced Technology Research Center (TATRC) is sponsoring the HF2 (Healthy Families, Healthy Forces) Study. This is a randomized trial comparing two different interventions for sustainable weight loss. Specifically, the investigators will compare a "current best practice (CBP)" intervention that includes standard dietary advice with a new, "Healthy Weight for Living (HWL)" intervention that includes recommendations to eat a diet rich in protein, dietary fiber, low glycemic index carbohydrates and low calorie foods. The objective of this study is to compare the CBP and HWL interventions when delivered to adult dependents of active duty (AD) military personnel and measure weight loss effects in both the adult dependents and the AD military personnel they live with.
