NCT01583725

Brief Summary

The investigators are looking at the differences in appetite and obesity between weight loss participants and patients undergoing bariatric surgery. Obese persons between the ages of 18 \& 65 are eligible to participate in this study, whether or not they intend to undergo bariatric surgery.

Outcome Measures

Primary Outcomes (1)

  • Change in brain activation in response to visual and auditory food cues

    Measures of brain brain activation in areas associated with food reward and motor planning, including the orbitofrontal cortex (OFC). Over the course of 40-min fMRI scans, we will compare change in activation from 3 mo pre-surgery to 3 and 18 mo post-surgery, and predict a post-surgical decrease in activation in such regions.

    3 mo pre-surgery and 3 and 18 mo post-surgery

Secondary Outcomes (4)

  • Anthropometrics and Body Composition

    3 mo pre-surgery and 3 and 18 mo post-surgery

  • Mood Measures

    3 mo pre-surgery and 3 and 18 mo post-surgery

  • Change in appetite-related gut peptide levels

    3 mo pre-surgery and 3 and 18 mo post-surgery

  • Eating Behavior

    3 mo pre-surgery and 3 and 18 mo post-surgery

Study Arms (5)

Roux-en-Y Gastric Bypass

EXPERIMENTAL

30 subjects who plan to undergo Roux-en-Y Gastric Bypass bariatric surgery. Liquid meal responses and Behavioral fMRI responses to food-cues will be assessed before surgery (T1), 3 months (T2) and 18 months (T3) after surgery.

Procedure: Liquid meal responsesBehavioral: fMRI responses to food-cues

Gastric Banding (Lap-band)

EXPERIMENTAL

30 subjects who plan to undergo Gastric Banding bariatric surgery. Liquid meal responses and Behavioral fMRI responses to food-cues will be assessed before surgery (T1), 3 months (T2) and 18 months (T3) after surgery.

Procedure: Liquid meal responsesBehavioral: fMRI responses to food-cues

Formula Diet Weight Loss

EXPERIMENTAL

30 subjects who plan to begin a formula diet to lose weight. Liquid meal responses and Behavioral fMRI responses to food-cues will be assessed before subjects undertake a 12-week weight loss intervention (T1), at the end of the weight loss intervention (T2) and 18 months after they completed the weight loss intervention(T3).

Procedure: Liquid meal responsesBehavioral: fMRI responses to food-cues

No Treatment

EXPERIMENTAL

30 subjects who do not undergo any treatment for weight loss. Liquid meal responses and Behavioral fMRI responses to food-cues will be assessed at baseline (T1) and at 3 months (T2) and 18 months (T3) later.

Procedure: Liquid meal responsesBehavioral: fMRI responses to food-cues

Sleeve Gastrectomy Surgery

EXPERIMENTAL

30 subjects who plan to undergo Sleeve Gastrectomy bariatric surgery. Liquid meal responses and Behavioral fMRI responses to food-cues will be assessed before surgery (T1), 3 months (T2) and 18 months (T3) after surgery.

Procedure: Liquid meal responsesBehavioral: fMRI responses to food-cues

Interventions

Subject ingests a meal-replacement shake and gut peptide levels are measured before and after intake.

Also known as: Meal replacement shake is the product Glytrol.
