This research study is being performed to begin to determine the effectiveness of two dominant bariatric surgery procedures versus an intensive lifestyle intervention to induce weight loss in patients and promote improvements in Type 2 diabetes mellitus (T2DM) in moderately obese patients. T2DM is currently the 6th leading cause of mortality in the United States and is a major cause of kidney failure, blindness, amputations, heart attack, and other vascular and gastro-intestinal dysfunctions. Traditionally, treatments include intensive lifestyle modifications with or without glucose lowering agents. Neither treatment alone, or in combination, results in complete resolution of diabetes and its potential long-term complications. Bariatric surgery has been proven as an effective treatment to accomplish sustained and significant weight loss for those with severe obesity and has been shown to induce long-term remission of T2DM. However, despite enthusiasm for these potential treatment options, it is not clear whether diabetes is influenced by the type of surgery or by the amount of weight lost or if bariatric surgery is more effective than non-surgical weight loss induced by diet and physical activity in T2DM patients with moderate BMIs (30-40kg/m2; Class I and Class II obesity, or approximately 65-95 pounds overweight depending on your height). More well-controlled studies are needed to more completely inform health care decision making and clinical practice in this area. This research study aims to obtain preliminary information regarding the effectiveness of two major types of bariatric surgery, Laparoscopic Roux-en-Y Gastric Bypass and Laparoscopic Adjustable Gastric Banding versus an intensive lifestyle intervention to induce weight loss with diet and increased physical activity.

Background: Trillions of tiny organisms-including bacteria, fungi, and viruses-live inside our intestines. These microorganisms break down nutrients in our food, aid our immunity, and help keep us healthy. The population balances among these organisms can vary in different people due to factors including genetics, lifestyle, and diet. More studies are needed to understand how dietary habits affect our intestinal microorganisms. Objective: To see how switching from a traditional Western diet (low in fiber, high in saturated fat) to a Mediterranean-like unprocessed foods diet (CLEAN-MED) changes the environment in the intestine. The CLEAN-MED diet includes lots of vegetables, fruits, and whole grains with little sugar or red meat. Eligibility: Healthy adults aged 18 to 60 Design: Participants will be divided into 2 groups. All will start with a trial week. Participants will log all the food they eat and answer questions about their diet throughout the entire study. Participants in the short-term group will eat a Western diet for 4 weeks and a CLEAN-MED diet for 4 weeks. Food will be provided for the CLEAN-MED diet. Participants will visit the clinic each week and complete surveys. They will log everything they eat. They will provide blood, urine, and stool samples. Participants in the long-term group will eat the CLEAN-MED diet for up to 12 months. They will visit the clinic each month and complete surveys. They will log everything they eat. They will provide blood, urine, and stool samples. Some foods will be provided for the first 2 weeks. Participants may choose to have a scan of their body composition every few months.

This study will assess the feasibility of delivering a 12-week time-restricted eating intervention as well as the intervention's preliminary efficacy on persistent cancer-related fatigue among cancer survivors compared to a general health education control. Participants will be randomized 1:1 to one of two arms: time-restricted eating or control. Those in the intervention arm will self-select a 10-hour eating window in which to consume all food and beverages (water is allowed any time, black coffee and unsweetened tea are allowed in the morning). Both groups will receive weekly educational tips on healthy lifestyle behaviors in cancer survivorship. This study will also explore relationships between fatigue, circadian rhythm, and glucose metabolism. The hypothesis is that recruitment will be feasible, and participants will adhere to time-restricted eating and complete study activities over the course of the 12 weeks. The second hypothesis is that time-restricted eating will lead to less fatigue at 12 weeks compared to the control, accounting for baseline fatigue levels.

TOTAL Program for Obesity

Madison, Wisconsin
Nearly 8 in 10 Veterans meet criteria for overweight/obesity. Three evidence-based treatment options are available within VA (behavioral weight management \[MOVE!\], obesity medications, and bariatric surgery). However, all treatments are significantly underutilized. This study will evaluate the effectiveness of a novel intervention designed to increase obesity treatment initiation and subsequently weight loss within VA. The intervention, Teaching Obesity Treatment Options to Adult Learners (TOTAL), involves an educational video and multiple motivational sessions delivered via telemedicine. If effective, TOTAL could be implemented throughout VA without requiring significant resources and could be integrated into the existing VA behavioral weight management program, MOVE!, which is present at nearly every VA medical center.

This project aims to study whether a structured wellness program intervention can improve quality of life among people living with Neuromyelitis Optica Spectrum Disorder (NMOSD). This pilot will test a multi-modal wellness program tailored to NMOSD patients that includes services from physical therapists, dietitians, social workers, nurse practitioners and cognitive therapists. The trial will be designed as a randomized controlled trial, randomizing patients to immediately starting the program as well as a 6 month delayed start. The intervention would leverage an existing clinical comprehensive MS wellness program at the Corinne Dickinson for Multiple Sclerosis (MS) at Mount Sinai Medical Center. The primary endpoint of this study would be evaluating quality of life, as assessed by MS-Quality of Life -54.

Remote Approaches for Weight Loss

Providence, Rhode Island
The purpose of this trial is to compare two delivery formats for weight loss (automated online program vs. group-based videoconference program) and to examine the added effect of individual coaching (vs. no coaching) for individuals with overweight or obesity. All participants enrolled in this study will receive a 12-month behavioral weight loss program (varying in delivery format and individual support), and will be provided with weight loss, calorie intake, and exercise goals. Assessments will occur at baseline, 6 (mid-treatment), 12 (post-treatment), and 18 months (following 6 months of no intervention). We will also seek to determine which combination of intervention approaches works best for whom and develop algorithms which can be used to refer patients into remote programs in clinical settings or future trials.

The goal of this clinical trial is to test if a regulation of craving training intervention in the form of a mobile phone app can increase fruit and vegetable intake in adolescent girls ages 14-18 years of age. The main questions it aims to answer are: 1. What is the effect of a mobile app version of the regulation of craving training intervention on healthy eating index scores over one year? 2. What is the effect of a mobile app version of the regulation of craving training intervention on body mass index, waist circumference, and blood glucose over one year? Researchers will compare the active regulation of craving training arm to a control fun food fact arm to see if the regulation of craving training improves HEI scores, BMI, and blood glucose over a year. Participants will be asked to play the regulation of craving training mobile app twice a week for a year.

Background: Diet is one of the most modifiable behaviors affecting health. But diet assessment measures that are based on self-report can be inaccurate. Researchers want better ways to address the role of diet in chronic disease. They want to see if stable isotopes can be used to better assess what people eat. Objective: To see if stable isotopes can help scientists identify things people eat. Eligibility: Healthy adults ages 18 to 65 Design: Participants will be screened with a medical history and physical exam. They will have blood and urine tests. These tests will be repeated during the study. Participants will stay in the inpatient unit of the NIH in Phoenix, Arizona, for 13 weeks. For 7 days, participants will eat a diet prepared by the NIH kitchen. They will get balanced meals that are 50% carbohydrates, 20% protein, and 30% fat. Then participants will be randomly placed on one of 3 diets containing different percentages of carbohydrates from soda. Participants height and weight will be measured. The amount of fat and muscle in their body will be measured by body scans that are similar to x-rays. Participants will have oral glucose tolerance tests. They will consume a sugar drink and then give blood samples over 3 hours. Participants will give hair and stool samples. Participants will complete a diet questionnaire. It assesses their food intake over 24 hours. Participants will complete behavioral questionnaires and computer performance tests. Participants will have fat biopsies taken from their stomach and thigh. Participants will have three 24-hour stays in a metabolic chamber. It is used to measure metabolism.

Why Other Patients Applied

"I've tried several different SSRIs over the past 23 years with no luck. Some of these new treatments seem interesting... haven't tried anything like them before. I really hope that one could work."

ZS
Depression PatientAge: 51

"I changed my diet in 2020 and I’ve lost 95 pounds from my highest weight (283). I am 5’3”, female, and now 188. I still have a 33 BMI. I've been doing research on alternative approaches to continue my progress, which brought me here to consider clinical trials."

WR
Obesity PatientAge: 58

"I've been struggling with ADHD and anxiety since I was 9 years old. I'm currently 30. I really don't like how numb the medications make me feel. And especially now, that I've lost my grandma and my aunt 8 days apart, my anxiety has been even worse. So I'm trying to find something new."

FF
ADHD PatientAge: 31

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

ID
Pancreatic Cancer PatientAge: 40

"As a healthy volunteer, I like to participate in as many trials as I'm able to. It's a good way to help research and earn money."

Frequently Asked Questions

How much do Diet Therapy clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Diet Therapy clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Diet Therapy trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Diet Therapy is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Diet Therapy medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Diet Therapy clinical trials?

Most recently, we added Remote Approaches for Weight Loss, Craving Regulation Training for Diet Modification and Wellness Program for Neuromyelitis Optica Spectrum Disorder to the Power online platform.
