Active clinical trials for "Insulin Resistance"

This study investigated any potential associations between two isocaloric diets with different meal frequency (3 meals versus 6 meals) and glycemic control in people at high diabetes risk (lean and overweight/obese women with PCOS, individuals with hyperinsulinemia, individuals with impaired glucose tolerance) and diagnosed with diabetes.

Our aim was to assess the effects of a hypocaloric diet, including diet fruit jelly with microencapsulated fish oil or conjugated linoleic acid or placebo, on anthropometry, body composition, insulin resistance and lipid profile in women with metabolic syndrome and genotype Pro12Pro in the PPAR gamma 2 gene.

Previous research has shown that indulging in 50% more calories than required for as little as 3 days can significantly impact markers of metabolic health in lean and overweight individuals. Here, the investigators will determine if 3 brief sessions of high-intensity interval training can mitigate the adverse consequences of 7 days high-fat overfeeding in sedentary, overweight males.

The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease. Dapagliflozin is an inhibitor of the sodium-glucose co-transporter SGLT2 in the kidney and is a novel treatment for diabetes type 2. Some studies indicate that SGLT2 inhibitors have benefits on blood pressure, triglycerides levels and help to raise the levels of high density lipoproteins cholesterol (c-HDL). The aim of this study is to evaluate the effect of dapagliflozin on metabolic syndrome, insulin sensitivity and insulin secretion. The investigators hypothesis is that the administration of dapagliflozin modifies the metabolic syndrome, insulin sensitivity and insulin secretion.

The purpose of this research study is to understand the effects of testosterone and estrogen on the body's response to the hormone insulin.

Diabetes Mellitus (DM) is a major risk factor for cardiovascular disease, with 50% of diabetes-associated deaths being attributed to cardiovascular complications. The characterising features of DM include: the presence of chronic hyperglycaemia, consequent upon decreased secretion or action of insulin; dyslipidaemia; and enhanced levels of oxidative stress and inflammation. Zinc and omega 3 polyunsaturated fatty acids have been shown to influence each of these outcomes via several mechanisms. This pilot study will examine the effect of nutritional supplements containing zinc and omega 3 on these outcomes in a population with type 2 DM.

The overarching aim of this proposal is to examine the effects of usual protein diet supplemented with keto acid (KA) on insulin sensitivity in patients on peritoneal dialysis (PD). The investigators will achieve this goal through a randomized controlled trial of administration of usual protein diet plus KA versus usual protein diet alone in patients on peritoneal dialysis (PD) over a period of 6 months. If successful, the results of this study will provide potential avenues for improvement of metabolic profile of patients on PD and possibly improve long-term outcomes such as cardiovascular disease risk and death.

Aims and priorities of the project The purpose of this study is to test the effect of frequency of meals (six vs. two meals daily with the same daily caloric restriction of -500 kcal/day) on insulin sensitivity, insulin secretion, and hepatic fat content. characterize some of the mechanisms of action of different frequencies of meals (amount of visceral fat, hepatic fat content, serum concentrations of adipokines, gut hormones, oxidation stress markers). test the ability of the participants to maintain hypocaloric diet on both regimens when educated and left to prepare their meals alone in comparison with those for whom all meals during the study will be provided. It will be a randomized, crossover study, where 50 individuals with type 2 diabetes will change in a random order two regimens: six, and two meals a day. Each testing period will take three months. Glucose and lipid metabolism and its regulation will be thoroughly tested at start, and after each 3-months-period (meal test, hyperinsulinemic isoglycemic clamp, indirect calorimetry, MRI scan of the liver, DXA scan, serum concentration determination of selected adipokines, gut hormones, and oxidation stress markers). Hypothesis The investigators hypothesize that low plasma insulin levels (as achieved by periods of fasting) will reduce insulin resistance and hepatic lipid content. In contrast, frequent meals (and consequent higher plasma levels of insulin) will predispose to non-alcoholic fatty liver disease and insulin resistance. The investigators further hypothesize that the participants will increase their caloric intake with increased meal frequency (in spite of thorough education) when left to prepare their meals in comparison with those for whom all meals will be provided.

Type 2 diabetes results when the body does not produce enough insulin and/or is unable to properly use the insulin it makes (insulin resistance). This study was undertaken to assess the effects of vildagliptin on insulin sensitivity in people with type 2 diabetes.

To test whether treatment with the angiotensin II receptor antagonist Irbesartan improves insulin sensitivity and metabolic profile in patients with chronic heart failure.
