We will employ both the preload-test meal paradigm along with rating scales in the present study to investigate the effects of rimonabant on satiety signaling. The testing will occur at baseline, week 8, and week 16 to see if the effect changes. All three testing occasions will be the same. Participants will arrive after skipping breakfast and given a preload of 12 oz. of Ensure (375 kcal) served chilled in a large, plastic cup. Hunger ratings will be taken at baseline, then every 30 minutes for 90 minutes. After 60 minutes a test meal consisting of a pre-weighed bowl each of Reduced Fat Wheat Thins and Nilla Wafers will be given. These will be kept in separate bowls so that exact caloric consumption can be measured. The test meal will be served with 12 oz. of water served chilled in a large plastic cup. Satiety will be assessed by the quantity of Wheat Thins, Nilla Wafers, and water consumed and the difference between the hunger rating score from baseline for each time point.
