Family Functioning in Obesity Treatment for Mexican Americans
open to eligible females ages 18-65
Mexican American families share similar elevated risks for obesity and obesity-related conditions, such as type 2 diabetes. Because negative family interactions and relationships (e.g., poor communication, high conflict, low emotional closeness) are associated with obesity treatment outcomes, this study tests a behavioral weight management intervention that provides relationship skills counseling to mothers and adult daughters. The goal is to improve family interaction patterns to buffer challenges and strengthen collaboration for eating and physical activity behaviors that support long-term weight management and thus provide an effective obesity treatment approach to address a major public health concern.

Optimization of Chrononutrition to Reduce the Risk of Disease in Shift Workers
open to eligible people ages 18-70
In this randomized controlled trial, the investigators will assess the health impacts of optimizing the timing of dietary consumption in nurses and nursing assistants who work night shifts, have a habitual eating window of 14 hours or more, and elevated weight. Participants will be randomized to one of three groups: (1) dietary monitoring, (2) dietary monitoring plus 10-hour daytime time-restricted eating (TRE), or (3) TRE with a low-glycemic snack during night shifts. The study includes a 2-week screening/baseline health assessment, with follow-up health assessments at 3-, 6- (primary outcome), and 12 months.

Semaglutide Treatment in the Real-world for Fibrosis Due to NAFLD in Obesity and T2DM
open to eligible people ages 40-79
Conduct a community intervention study that will 1) validate a screening approach to identify patients at risk for advanced NAFLD in the obese or T2DM population, and 2) test whether semaglutide treatment is effective for the management of significant fibrosis due to NAFLD in high-risk patients.

Fenretinide Administered in Subjects With Obesity
Sorry, currently not accepting new patients, but might later
Many metabolic complications of obesity are a consequence of abnormal responses of the liver, muscle, and fat to insulin actions. Fenretinide may improve the effects of insulin, preventing metabolic complications.

ADRB3 Signaling Pathway in Human Adipose Tissue
Sorry, in progress, not accepting new patients
This study will examine the gene expression of the adrenergic Beta-3 receptor (ADRB3) regulation in human subcutaneous adipose tissue before and after treatment with mirabegron, an ADRB3 agonist. Gene expression will be compared across two groups, lean and obese participants. There will be a total of three study visits: Screening/Eligibility, Pre-Dose Adipose Tissue Biopsy and Post-Dose Adipose Tissue Biopsy. Participants will be given a single dose of 100mg oral mirabegron on the day of the Post-Dose Adipose Tissue Biopsy.The trial design is a single-center, phase 1, open-label, exploratory study to examine the adipocyte gene expression in adults treated with 1 dose of 100mg oral mirabegron.

Breast Cancer WEight Loss Study (BWEL Study)
Sorry, in progress, not accepting new patients
This randomized phase III trial studies whether weight loss in overweight and obese women may prevent breast cancer from coming back (recurrence). Previous studies have found that women who are overweight or obese when their breast cancer is found (diagnosed) have a greater risk of their breast cancer recurring, as compared to women who were thinner when their cancer was diagnosed. This study aims to test whether overweight or obese women who take part in a weight loss program after being diagnosed with breast cancer have a lower rate of cancer recurrence as compared to women who do not take part in the weight loss program. This study will help to show whether weight loss programs should be a part of breast cancer treatment.

Time-restricted Eating on Catecholamine-sensitivity of Adipose Tissue in Obese Adults
Sorry, in progress, not accepting new patients
In a randomized controlled trial, the investigators intend to measure the health impact of time-restricted eating (TRE) in obese patients (body mass index (BMI) ≥ 30 kg/m2), who habitually eat for more than 14 hours every day. Patients will be randomly assigned to a control group of behavioral nutritional counseling (standard of care) or the intervention group of behavioral nutrition counseling with the addition of adopting a 10-hour eating window for 12 weeks (TRE).

Negative Affect in Individuals With Binge Eating Episodes
Sorry, in progress, not accepting new patients
Binge-eating is characterized by recurrent episodes of eating large amounts of - typically high calorie - foods, eating much more rapidly than normal and until feeling uncomfortably full, as well as feeling disgusted with oneself, depressed, or guilty after those episodes. Two eating disorders are characterized by binge-eating as central diagnostic criteria, binge-eating disorder (BED) and bulimia nervosa (BN). Binge-eating episodes in BN, but not BED, are typically followed by compensatory mechanisms such as self-induced vomiting, and BED is typically associated with obesity, while BN is not. Behavior studies such as ecological momentary assessment (EMA) research of affect in an individual's naturalistic environment have shown that negative affect and negative urgency (the tendency to act rashly when distressed) often precede binge-eating. The Investigators want to answer the following questions: Can negative affect in BN and BED be linked to 1) altered dopamine related brain reinforcement learning, 2) to food value computation and cognitive control circuit function, and 3) can dopamine related brain activation predict eating and negative affect, indicating a brain based neurobiological vulnerability. Answering those questions will help to define binge-eating based on regulation of brain reward, cognition, and emotion circuit function and point toward potential psychopharmacological interventions to normalize brain function and behavior.

Sorry, in progress, not accepting new patients
The objective of this proposed study is to collect initial efficacy data on a telehealth family-based behavioral program for Latino children with overweight or obesity, which also includes additional caregiver support (PBT-AC), compared with health education (HE).

Test Whether Time-restricted Eating Coupled with a Healthy Diet is Beneficial in Liver Cancer Patients
Sorry, not yet accepting patients
This is a feasibility study that will collect data to assess the potential effect of a nutritional intervention designed to improve liver metabolism. This prospective single-site trial will enroll adult patients undergoing liver-directed therapies for hepatocellular carcinoma. Eligible individuals who are randomized to the intervention group will be enrolled in a six-month nutritional change program consisting of time-restricted eating in which calorie consumption is limited to 8-10 hours during the day, plus targeted healthy changes in what they eat. The intervention includes dietary counseling visits with a study registered dietitian and motivational phone calls with a study Certified Health and Wellness Coach to help subjects adhere to the intervention. Individuals in the control group will be enrolled in a six-month period of observation only. The main questions it aims to answer are: Is a prolonged nightly fast coupled with a healthy diet safe and feasible for patients with liver cancer? Does the intervention improve liver metabolism?
