Filter by:Diabetes and heart associations continue to discourage high intakes of dietary fructose, a constituent part of the sucrose molecule that is found in fruits and vegetables as a natural sugar and in some processed foods and beverages as an added sweetener. The concern relates to its ability to increase certain blood fats and cholesterol, which increase the risk of cardiovascular disease. The evidence for an adverse effect of fructose on these risk factors, however, is inconclusive. To improve the evidence on which nutrition recommendations for fructose are based, the investigators therefore propose to study the effect of fructose on blood fats, cholesterol, sugars, blood pressure, and body weight, by undertaking a systematic synthesis of the data taken from all available clinical studies in humans. This technique has the strength of allowing all of the available data to be pooled together and differences to be explored in groups of different study participants (healthy humans of different sex, weight, and age and in those with diseases which predispose to disturbances in metabolism, such as diabetes) with dietary fructose in different forms, doses, and with differing durations of exposure. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing recommendations for the general public, as well as those at risk of diabetes and cardiovascular disease.
The objective of this study is to investigate the effect of calcium (Ca) and vitamin D (D) supplemented orange juice (OJ) on weight loss and visceral fat mass in overweight and obese adults.
Obesity may have implications on the individual's participation in working life through different mechanisms such as comorbidity and loss of functional level. The investigators also know that when exiting the working force, it is difficult to get back later. As rehabilitation back to working life is often not a very focused aim with weight loss treatment, this study sets this as a primary aim by involvement in a 4 week stay at a rehabilitation clinic followed by 48 weeks work practice programme at one of three different companies.
The purpose of this study is to evaluate the efficacy of a parent intervention (NOURISH+) aimed at reducing the problem of overweight and obesity in children.
- The primary aim of this study is to determine the adherence of low- carbohydrate among Chinese. - Then compare the effect of low-carbohydrate and traditional Chinese but restricted-calories diet on weight loss and metabolic traits.
The purpose of the Take Charge Study is to determine among overweight and obese men and women with type 2 diabetes whether 1) participating in a commercial weight loss program promotes great weight loss and weight loss maintenance at one year compared to usual care conditions and 2) whether there is a differential weight loss response to different dietary macronutrient composition (lower carbohydrate/higher fat diet versus a higher carbohydrate/lower fat).
The investigators investigated the effect of vitamin D3 supplementation on metabolic profile (anthropometric measures, blood pressure Lipids, lipoproteins and glycemic indices) in overweight or obese women.
Obesity has been linked to several serious medical conditions, including high blood pressure, diabetes, and poor cholesterol levels. For this reason, obesity is likely the most important single contributor to cardiovascular mortality in the United States. Fortunately, intensive weight management programs are an effective treatment for obesity. Such programs help people lose weight and improve their measures of cardiac risk. In response to the growing numbers of obese veterans being treated at VHA facilities, the Department of Veterans Affairs developed the MOVE! Program. Veterans who commit to MOVE! and participate actively do lose weight. Unfortunately, MOVE!, like other weight management programs, requires its participants to attend classes and to exercise, often at locations and times that are inconvenient. The investigators propose to make it easier for eligible patients at the Zablocki VAMC to participate by offering MOVE-style classes and exercise groups at a variety of locations, days, and times. Our program-MOVE OUT-may provide a model for VHA to use nationwide.
- Objectives Taking a 'whole foods' approach, we will investigate (i) whether consumption of isocaloric diets containing ≥4 vs. ≤1 servings of dairy products per day for 16 weeks results in greater body fat loss in energy-restricted overweight/obese premenopausal women; (ii) the role of dairy product consumption in influencing physiological and metabolic factors which may precede or accompany changes in body composition, including in enzymes which synthesize and break down body fat; and (iii) factors, including obesity phenotype, which may influence the response of body composition to dairy product consumption. - Background With the obesity epidemic showing no signs of abating, there is ongoing interest, both at the lay public and scientific levels, in manipulating the diet to promote weight, specifically fat, loss. One such promising manipulation is an increase in, or perhaps more precisely, an isocaloric substitution of, dairy product consumption. The inverse association between Body Mass Index (BMI) and dietary calcium - for which dairy products are the main source - was first described in 1984 and has since been supported by various levels of evidence, but not consistently. Heaney recently described this literature as "confused," which he and Rafferty attribute to important limitations in study design, including lack of low-calcium contrast groups and the fact that body weight/body composition is often a secondary endpoint in studies designed and powered for a different outcome, typically bone health or blood pressure. Confusion has also arisen from the investigation of different interventions (dairy products, dairy calcium, dietary calcium, supplemental calcium), making it difficult to compare and interpret studies. This creates an opportunity for the proposed Dairy and Weight Loss (DAWL) study, with its focus on whole dairy product consumption, to help clear up the confusion surrounding this issue. **Hypotheses Overweight/obese, low habitual dairy consuming, premenopausal women randomized to an energy-restricted weight loss diet containing ≥4 servings/day of dairy products (milk, yogurt, cheese) for 16 weeks will lose more body fat than those randomized to an isocaloric diet containing ≤1 servings/day of dairy products.
The investigators aims in the current study are to examine whether the cholinergic status should be considered as another risk factor for the metabolic syndrome and it's co-morbidities and to test the effect of a hypocaloric high complex carbohydrates diet on the cholinergic status of overweight and obese adults with and without the metabolic syndrome.
