Oro-gastro-intestinal Digestion of Emulsified Fat
ObesityInteraction of fat with the mouth, stomach and intestine will trigger physiological responses that will impact on the digestion, gut transit time and absorption of fat. These responses will also influence and contribute to regulation of food intake and satiety. No systematic research on understanding how the physiological-chemical properties of food affect the digestion and absorption of lipids has been carried out previously. Studies have shown that the release of free fatty acids triggers the fat-related responses. The investigators hypothesize that the release of fatty acids depends on the colloidal state of the fat, which changes progressively due to the pH changes and enzyme activities in the mouth, stomach and intestine.

DiabetesObesity1 moreThis program aims to help Veterans who take antipsychotic medications lose weight. We use a program based on the American Diabetes Association's "Diabetes Prevention Program," and we have modified it to fit the lifestyles of people with mental illness. All participants are educated about nutrition and cutting down fat intake, how and when to exercise, and the causes of diabetes and how to prevent it. Participants must be Veterans who live within one hour of the Long Beach, West Los Angeles, Sepulveda, or West Los Angeles VA hospitals.

A High Protein Diet and Weight Maintenance
ObesityAn investigation into long term weight maintenance using a high protein or high carbohydrate diet, after a large and rapid weight loss.

Cognitive Behavioral Therapy for Obesity
ObesityThe purpose of this pilot study is to assess patient accessibility, interest and response in order to design an adequately powered study to compare brief, group cognitive behavioral therapy (CBT) for weight loss to usual care in non-demented patients above the age of 18 years old who are currently taking atypical antipsychotic medications. This pilot study is necessary, with current limitations of data in this area, to design an adequately powered study to address the difficulties managing metabolic syndrome risk factors in patients on antipsychotics.

Sandostatin LAR® Depot in Patients With Primary Insulin Hypersecretion (PIH) and at Least Moderate...
Primary Insulin HypersecretionObesityThis study is in patients with at least moderate obesity (Body Mass Index [BMI] > 30 kg/m2 or approximately 30 or more pounds overweight) and who also produce too much insulin (insulin stores sugar as fat). Sandostatin LAR® Depot suppresses insulin, and is being developed to help with weight loss in people who find it hard to lose weight on their own because they produce too much insulin. The main purpose of the study is to find the lowest dose of Sandostatin LAR® Depot that safely helps overweight people lose weight. The study will also compare weight loss in obese patients who receive one of three different dosages of Sandostatin LAR Depot or placebo.

A Study of Octreotide Depot vs Saline Control in Pediatric Hypothalamic Obesity Patients
Hypothalamic ObesityThe extension protocol is designed to allow those patients randomized to placebo in the core portion of the protocol to receive a 6 month treatment of open label octreotide and allow those patients randomized to octreotide who appeared to benefit from treatment, to continue to receive octreotide.

Factors Affecting Caloric Regulation in Human Feeding
ObesityThis study will test the hypothesis that reducing the energy density of the diet by incorporating more water-rich foods will result in: 1) greater weight loss and weight maintenance; 2) greater diet satisfaction and satiety; and 3) more healthful dietary patterns than reducing dietary fat alone.
