Filter by:Dairy food contains a large amount of long-chain saturated fat, which traditionally has been linked to increased risk of cardiovascular disease (CVD). However, recent data indicates a more neutral role. Milk fat contains large amounts of medium-chain saturated fatty acids (MC-SFA), which may have beneficial effects on human health. In addition, milk proteins and in particular whey proteins have been shown to have a beneficial effect on glucose disposal as well as anti-inflammatory properties. Therefore dairy products have a potential role in the treatment of the metabolic abnormalities of metabolic syndrome (MeS). However, human data from intervention studies are lacking. Aims of this project is to explore and understand the influence on human health of both medium-chain saturated fatty acids from milk fat and bioactive milk proteins per se as well as their interaction and potential positive synergy on the MeS. The investigators hypothesize that whey protein and medium-chain saturated fatty acids improve insulin sensitivity, postprandial lipid metabolism, blood pressure and inflammatory stress in humans and that they possess preventive effects on the risk of developing CVD and type 2 diabetes mellitus (T2DM). A total of 64 people with MeS or abdominal obesity will be included. The design is a randomized double-blinded, controlled parallel diet-intervention trial. Subjects are assigned one of four experimental diets for 12 weeks. The diets consist of either a diet with low levels of MC-SFA + whey protein (LF + whey), a diet high in MC-SFA + whey protein (HF + whey), a diet high in MC-SFA + casein protein (HF + casein) or a diets with low levels of MC-SFA + casein protein (LF + casein). The subjects are advised how to integrate the test foods in their habitual diet, which also continues unchanged. The subjects' energy intake is matched so they are kept weight stable throughout the study.
In this randomized controlled trial, we will examine the effect of a 3-month exercise training (aerobic exercise versus resistance exercise) without calorie restriction on total and regional adiposity, ectopic fat in the liver and skeletal muscle, and risk of type 2 diabetes in overweight girls.
The main objectives of this study are to collect pilot data to assess feasibility (accrual, retention, compliance), to estimate the variability of outcome measures, and to obtain preliminary estimates of treatment efficacy based on group differences in body composition (decreases in ectopic fat stores while maintaining lean mass), cardio-metabolic risk factors including glucoregulatory function (glucose, insulin), inflammation (C-reactive protein, IL-6), blood pressure and lipids (HDL, LDL, TC, TG), and measures of physical function and muscle strength. While this is just a pilot study, randomization will be used so that the investigators can obtain a realistic estimate of accrual (which is often less in a randomized trial) and an unbiased estimate of treatment efficacy. The investigators will accomplish these objectives by conducting a 2-arm, 3-month randomized, clinical trial in 24 older (60-79), abdominally obese (BMI ≥30 kg/m2 and waist circumference ≥ 102 cm and ≥ 88 cm in men and women, respectively) men and women. Participants will be randomized to a soy-based or animal-based, 3-month, hypocaloric dietary intervention to achieve our specific aims: Primary Aim: To determine our ability to recruit and retain older, obese adults to a 3 month soy-based meal replacement weight loss intervention and assess the study participant's ability to adhere to the intervention protocol (weight, compliance logs, serum isoflavones). Secondary Aims: 1. To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on measures of body composition, including abdominal (total, subcutaneous and visceral fat), liver, and pericardial fat; anthropometrics (body weight, waist/hip circumference); and whole body fat and lean mass. 2. To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on biomarkers of cardiometabolic risk including glucoregulatory function (glucose, insulin), inflammation (C-reactive protein, IL-6), blood pressure and lipids (HDL, LDL, TC, TG). 3. To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on physical function (short physical performance battery, 400-m walk) and muscle strength (grip and knee extensor strength) and size (CT thigh muscle). 4. To document any adverse events associated with the soy-based meal replacement.
The purpose of this study is to evaluate the efficacy of GFT505 80mg compared with placebo in improving Oral Glucose Tolerance Test (OGTT), in patients with impaired glucose tolerance and abdominal obesity, and to assess the tolerability and safety of once-a-day administrations of oral doses of GFT505 during 35 days.
The purpose of this study is to demonstrate the efficacy on insulin sensitivity of GFT505 at 80mg/d in male patients with insulin resistance and abdominal obesity. Evaluation will be made using a glucose clamp technique.
The purpose of this study is to evaluate the efficacy of GFT505 80mg in reducing serum Triglycerides (TG) and increasing High Density Lipoprotein Cholesterol (HDL-C) levels compared with placebo in atherogenic dyslipidaemic patients with abdominal obesity, and to assess the tolerability and safety of once-a-day administrations of oral doses of GFT505 during 28 days.
The main purpose of this 2-year lifestyle experiment for waist loss is twofold: 1. to compare whole grains and no grains as part of a healthy diet, 2. to determine if an 8-week exercise program, led by physiotherapists, is more efficient than brief counseling and follow-up. People with abdominal overweight (≥84 cm in women and ≥98 cm in men) and at least one additional cardiovascular risk factor, (typically hypertension, diabetes type 2 or prior cardiovascular disease) are randomly assigned to receive Diet A or Diet B, with or without a structured exercise program at the department of physiotherapy, or to a control group receiving usual care. Diet A and B both include fruit, vegetables, fish, meat, and low-fat dairy products, and differ only in that Diet A recommends exchange of cereal grains for more potatoes, root vegetables, fruit and other carbohydrate-rich foods, while Diet B recommends exchange of regular cereal grains for whole grains. The primary outcome (most important follow-up variable) is change in waist circumference during 2 years. Secondary outcome measures include blood pressure, blood lipids, level of physical activity and, in subjects with diabetes, glycated hemoglobin and fasting blood sugar.
High blood pressure (hypertension) is an important cause of myocardial infarction and stroke. High blood pressure often occurs in people who are overweight. These people frequently also have abnormal fat and sugar metabolism. The combination of these problems is called the 'metabolic syndrome'. People with hypertension and obesity currently receive the same drug therapy as people with hypertension, but without obesity. Different classes of drugs are thought to be equally effective in lowering blood pressure. Next to lowering blood pressure, hypertension treatment can have additional effects, like changes in blood vessel function (the ability to dilate and constrict) or changes is the metabolism of sugar and fat. Particularly in patients with the metabolic syndrome, these additional effects are thought to be of great importance, because they can influence the risk for cardiovascular diseases. The blood pressure lowering mechanism differs between classes of blood pressure lowering medication. The purpose of this study is to compare the effects of three types of blood pressure lowering medication belonging to different classes. The main outcomes of interest will be blood vessel function (the ability to dilate and constrict) and blood pressure. Moreover, the effect of treatment on additional outcomes, like metabolism of sugar and fat, will be studied.
The purpose of this study is to investigate whether 6 months treatment with the cholesterol-lowering drug rosuvastatin may reduce visceral fat tissue in obese middle aged men.
SYSDIET (Systems biology in controlled dietary interventions and cohort studies) is one of the three centres in the NCoE Food, Nutrition and Health, 2007-2011. It consists of 12 partners from five Nordic countries working on multidisciplinary fields of science related to nutritional biology. The main objective of SYSDIET is to reveal mechanisms by which Nordic foods and diets could be modified to promote health and prevent insulin resistance, type 2 diabetes and cardiovascular diseases, all of which being connected to metabolic syndrome. Furthermore, the aim is to build up a Nordic platform for cohort studies and carefully conducted multi-centre dietary intervention studies, where novel nutritional systems biology tools can be applied besides human studies also in animal and cell culture studies. In order to achieve the main objective a Nordic multi-centre randomized controlled human intervention study is being conducted in 2009-2010 in 6-8 centres of SYSDIET consortium. Health of the Nordic populations has substantially improved during the last 30 years. This is due e.g. to marked decline in cardiovascular morbidity and mortality. However, during the last 10-20 years increasing obesity and sedentary lifestyle have resulted in an increase of metabolic syndrome and type 2 diabetes. Having this background, the aim of the SYSDIET consortium is to carry out a controlled, randomized dietary intervention study in persons with features of metabolic syndrome to find out the effects of a healthy Nordic food on major abnormalities in metabolic syndrome. Altogether 167 persons aged 30 to 65 years were recruited from 6-8 centers (40-60 subjects/center) of the SYSDIET cohort. The main inclusion criterion is BMI 27-38 kg/m2. The subjects should also have at least two other IDF criteria for metabolic syndrome. Recruited persons will start the study by following their conventional diet for one month as a run-in period. After that subjects will be randomly assigned into Experimental- or Control-diet-group for 6 months. Experimental diet is rich in whole grain products, berries, fruits, vegetables and fish, and its fat intake is modified according to current Nordic recommendations. Control diet is based on the current information of the mean dietary intake and food consumption. The diets will be realized according to eating habits in each Nordic country.
