Dietary Protein Requirements on Unbalanced Diets
ObesityOverweightThe objective of this study is to determine ad libitum daily energy and protein intake, energy balance and appetite profile in response to protein/carbohydrate and fat ratio over 12 consecutive days, also as a function of age, gender, BMI and FTO polymorphisms.

A Test of Nutritional Interventions to Enhance Weight Loss Maintenance
OverweightObesity1 moreThe purpose of this study is to compare standard Behavior Therapy (BT), BT plus Meal Replacements (MR) and a condition focusing on the nutritional changes to the home food environment (HFE) on weight loss, weight loss maintenance, nutritional composition of the diet and psychosocial outcomes. A second aim is to determine the degree to which the specific targets of the experimental interventions do in fact change in the anticipated direction during the intervention and to evaluate whether such changes might account for improvements in weight loss maintenance. This study is important because it could provide the first evidence that the current standard of care for obesity lifestyle treatment could be improved by the addition of MRs or a program of comprehensive nutritional change.

Use of Chewing Gum to Facilitate Appetite Control and Weight Loss
OverweightObesityThis purpose of this study was to test the use of chewing gum as an adjunct to lifestyle modification to facilitate appetite control and weight loss in overweight and obese individuals.

Effects of Medium Chain Triglyceride Oil, Versus Olive Oil, for Weight Loss
OverweightThe primary aim of this research project is to determine whether the incorporation of food products containing medium chain triglyceride (MCT) oil in a weight-loss program results in a different degree of weight-loss and total and regional fat mass loss than the incorporation of extra light olive oil. The secondary goals are to test whether there are differences in in metabolic risk profile changes between the 2 diets. We hypothesize that men and women who consumed MCT oil as part of their weight loss program will lose more weight and body fat than those who consume olive oil in their weight loss diet.

Weight Loss Maintenance in Primary Care
ObesityOverweightAfter a three month weight loss phase involving the use of meal replacements, participants are randomized into different weight loss maintenance conditions. Aim 1: To test the hypothesis that the meal replacement (MR) and reduced energy density eating (REDE) interventions, when added separately to the LEARN program, will produce superior weight loss maintenance compared to a LEARN-only intervention. Aim 2: To test the hypothesis that the weight loss maintenance condition that combines MRs and REDE will produce better maintenance of weight losses than either individual component and than the LEARN-only condition. Aim 3: To test the hypothesis that the two conditions receiving the REDE intervention will experience longer-lasting improvements in the energy density and nutritional composition of the diet compared to the two non-REDE conditions.

Bicalutamide With or Without Metformin for Biochemical Recurrence in Overweight or Obese Prostate...
Cancer of ProstateObesity and metabolic syndrome are prevalent among prostate cancer patients. Having an elevated insulin level in the blood is associated with a shorter median time to cancer progression and median overall survival in patients with an elevated PSA after prior treatment. Androgen deprivation therapy (ADT) with drugs like bicalutamide is frequently used in this patient population,with no proven benefit, which may increase mortality and morbidity.This study evaluates how metformin in combination with bicalutamide affects prostate cancer.

Screening for Endometrial Abnormalities in Overweight and Obese Women
Endometrial CancerThe purpose of this study is to develop an endometrial biopsy screening program for endometrial cancer and its precursor lesions in overweight and obese women. There is a BMI threshold at and above which optimal screening parameters exist for identifying endometrial cancer and its precursor lesions in overweight and/or obese women. Prevention, diagnosis and treatment of endometrial cancer and its precursor lesions in overweight and/or obese women offers substantial health benefits.

CrossFit Exercise to Improve Glucose Control for Overweight and Obese Adults
HyperglycemiaThe purpose of this study was to examine the differences in glucose control, fitness, and body composition between a standard aerobic and resistance exercise training program and a shorter-duration, high-intensity CrossFit training program in overweight and obese physically inactive adults. Hypotheses: Both groups would improve glucose control, with the CrossFit group improving significantly more than the aerobic and resistance training group. Both groups would improve fitness, with the CrossFit group improving significantly more than the aerobic and resistance training group. Both groups would demonstrate decreases in body fat percentage and fat mass and increases in lean body mass, with the CrossFit group improving significantly more than the aerobic and resistance training group.

Weight Management in Mothers and Adult Daughters
Overweight or ObeseThe purpose of this study is to develop, implement, and evaluate a behavioral weight management intervention with a communication training component for Mexican-American women. The study has three specific aims. Aim 1: Develop a behavioral weight loss intervention that modifies evidence-based behavioral weight loss treatment using results from formative data collected from Mexican-American mother-daughter dyads. The adapted intervention will focus on improving dyadic communication and collaboration for providing reciprocal support for healthy eating and physical activity behaviors. Aim 2: Implement and evaluate a pilot weight management program adapted for mother-daughter dyads. Dyads will be randomly assigned to partner-based treatment with or without communication skills training. Aim 3: Evaluate associations between changes in weight, weight-related behaviors, and psychosocial variables with changes in measures assessing interpersonal communication.

The Effects of a Commercially Available Weight Loss Program on Body Weight in Overweight Men and...
Overweight and ObesityWeight LossThe primary purpose of this study (Part A) is to assess changes in body weight and body circumference parameters that are achievable after 4 weeks on the Nutrisystem program compared to a self-directed diet (i.e. Dietary Approaches to Stop Hypertension or DASH). In Part B, subjects on the Nutrisystem program will be given the option to continue the program for another 8 weeks.
