Adipose tissue turnover plays a critical role in body weight maintenance, and obesity is underscored by the dysregulated balance between fat breakdown and synthesis. Although there are clear health-related benefits of physical activity, little is known about how resistance exercise, as opposed to endurance exercise, can reduce the risk of metabolic disorders, particularly in women. The goal of the proposed study is to investigate the effectiveness of resistance training to improve basal and stimulated fat metabolism in postmenopausal women with obesity and pre-diabetes, potentially serving as a viable and practical approach to prevent the onset of type 2 diabetes.
The study will find out if 100 minutes of electrical stimulation of muscle prevents the unfavorable consequence of insufficient exercise.
Long-chain cyclopropane fatty acids (CpFAs) are microbially-derived lipids (fats), some of which can be found in select foods and appear to be produced naturally in the gut from dietary fatty acid precursors. Some of these lipids appear to have signaling properties in the body's tissues, i.e., to help regulate cardiometabolic health. Thus, increasing the bioavailability of CpFAs in humans may have utility to improve management of blood sugar and blood lipids, or to mitigate or prevent non-alcoholic fatty liver disease (NAFLD). This study is a proof-of-principle experiment in 10 subjects, to feed dietary fats thought to enhance upper gut CpFA production. The latter will be monitored through post-meal blood and urine CpFA concentration measurements, as well as concentration in the stool.
