Clinical Trials

To determine the mechanism of monocyte priming in humans, the study team will conduct a complete feeding trial in normal weight and metabolically healthy human subjects (20-45 years of age) using a western diet (WD), characterized as being high-saturated fat, high-fructose, and high-calorie for 8 weeks.

The purpose of this micro-randomized trial is to evaluate the effects of 7 types of intervention messages targeting specific behavior change techniques (i.e., BCT messages) delivered in "just-in-time" (JIT) moments on daily achievement of weight-related behavioral goals among n=201 young adults with overweight and obesity, participating in a digital, mobile comprehensive lifestyle intervention.

The goal of this investigational study is to develop algorithms that predict human response to foods.

Are you an adult who has overweight or obesity and would be interested in a weight-loss study? This study is testing whether a medicine called phentermine is safe and effective for treating obesity over a long period. This study has multiple locations in the United States.
