Overweight/Obese Women clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Dietary Fatty Acid Composition and Obesity-related Metabolic Abnormalities

Start date: August 2007
Phase: N/A
Study type: Interventional

Individuals have a significant capacity to adapt to different environments by changing their core metabolic pathways. This adaptation is especially important in regards to diet. Epidemiological research over the last several decades have shown that diets high in saturated fats have a greater ability to cause insulin resistance and the 'metabolic syndrome' while diets low in saturated fats (or a so called 'Mediterranean Diet), reduces the risk for cardiovascular disease. In humans, experimental diets high in unsaturated fats, as compared to high carbohydrate or high saturated fat diets, result in increased insulin sensitivity and improved lipid profiles. In this application, the investigators propose to systematically assess the effects of two diets enriched in either saturated or unsaturated fatty acids and determine the cellular and molecular mechanisms of the apparent increase in insulin sensitivity. The investigators hypothesize that individuals will 'adapt' to the different diets and the investigators will be able to generate predictive alterations in gene expression and metabolites that underlie the alterations in metabolism. In parallel, the investigators will test the ability of these different diets to affect the release of gastrointestinal hormones that may be critical to modulation of appetite.
