Clinical Trial Summary

The main purpose of this study is to assess factors mediating the changes in insulin sensitivity and glucose tolerance before and after 10 lbs ± or 2% weight loss reduction as well as 2, 3, 6, 12, and 24 months after initiation of a low calorie diet.

The investigators will also study the following:

1. The impact of diet induced weight loss on hormones/adipokine levels

2. The impact of diet induced weight loss on leptin tolerance

Intervention

Dietary Supplement:
Weight loss group (Full meal replacement products)
In the intervention arm of this non randomized, open label study to assess the effects of weight loss on insulin sensitivity and leptin tolerance subjects will use full meal replacement products (1280-1320kcal/day). Subjects will be on the full meal replacement products only, for the first 12 weeks, between 13 to 19 weeks they will be transitioned to regular food, from 19 weeks and going forward they will be on chronic maintenance phase

Outcome

Type Measure Description Time frame Safety issue
Primary The primary outcome will be the difference in insulin and leptin tolerance after weight loss 8 weeks (10 ± 2% body weight reduction) No
Secondary Difference in brain signaling before and after the 10 ± 2% body weight reduction. We will examine the impact of weight loss on human brain responses to food visualization using functional magnetic resonance imaging (fMRI) and assess whether the baseline CNS signaling has any effect on the ability to lose and maintain weight 8 weeks (10 ± 2% body weight reduction) No
