Addressing Weight Bias Internalization to Improve Adolescent Weight Management Outcomes: Open Trial

Weight stigma and weight bias internalization (WBI) are common among adolescents at higher weight statuses. WBI is associated with negative physical and mental health outcomes. The current study aims to test intervention for weight stigma and WBI in conjunction with an evidence-based adolescent weight management program. Adolescents (ages 13-17) will participate in a 20-week program tailored to improve WBI and weight-related health behaviors in tandem. Primary outcomes are feasibility and acceptability of the developed intervention, assessed following the 20-week intervention.

A Study of PF-08653945 and PF-08653944 in Adults With Overweight or Obesity

This study is being done to learn about the safety and effects of the study drugs, PF-08653945 and PF-08653944, when given alone or together for weight loss, compared to a placebo (a dummy drug that has no active ingredient in it).

Impact of Bright Light Therapy on Prader-Willi Syndrome

This is a placebo controlled clinical trial to assess the utility of light therapy as a sufficient treatment for excessive daytime sleepiness in patients with Prader-Willi Syndrome

The Intersection Between Loss of Control Eating and Obesity: The Role of Restriction and Food Reinforcement

This study aims to determine the relationships among loss of control eating, restriction, relative reinforcing value of high energy-dense food, and obesity risk. In order to achieve this aim, the investigators will follow children over the course of a year, obtaining behavioral and observational measurements, in addition to a two-week restricted access and two week non-restricted access period.

The Effect of a Meatless,Keto Restrictive Diet on Body Composition,Strength Capacity,Oxidative Stress,Immune Response

The subject of doctoral dissertation: Assessment of the effects of a meatless, ketogenic restrictive diet on body composition, strength capacity, oxidative stress and immune response During planning of research and topic of the doctoral dissertation, it was considered how to modify a standard ketogenic diet rich in saturated fatty acids so that the use of this model of nutrition has the most anti-inflammatory effect. Therefore, it was decided to conduct a research to check whether a diet rich in omega-3 polyunsaturated fatty acids will show such an effect when following a high-fat diet. Hypotheses: 1\. The ketogenic diet reduces systemic inflammation. 2.The ketogenic diet reduces oxidative stress. 3. The ketogenic diet reduces body fat. 4. A ketogenic diet does not worsen strength performance.

Body Mass Index (BMI) and Quality of Life (QoL) in Cancer Patients

BMI is a simple and widely recorded variable that may capture obesity or cachexia in cancer patients. How BMI is associated to health-related quality of life (HR-QoL) in such patients is poorly investigated. High BMI may be associated to obesity, an increased burden of comorbidity, reduced physical activity and, in some settings, to more aggressive oncological disease. On the other hand, low BMI may reflect enhanced weight loss, cachectic syndrome, higher tumor burden and adverse prognostic features which all deteriorate quality of life. The aim of the present study is to evaluate the association of BMI and HR-QoL as measured by the EORTC-QLQ-C30 or the EQ-5D-5L questionnaire in several cancer settings (such as localized vs metastatic or distinct primary tumors).

Metabolic and Bio-behavioral Effects of Following Recommendations in the Dietary Guidelines for Americans

This study, at the Western Human Nutrition Research Center (WHNRC), will focus on whether or not achieving and maintaining a healthy body weight is the most important health promoting recommendation of the Dietary Guidelines for Americans (DGA).The investigators hypothesize that improvement in cardiometabolic risk factors resulting from eating a DGA style diet will be greater in people whose energy intake is restricted to result in weight loss compared to those who maintain their weight. The investigators further propose that during a state of energy restriction, a higher nutrient quality diet such as the DGA style diet pattern, will result in greater improvement in cardiometabolic risk factors compared to a typical American diet (TAD) pattern that tends to be lower nutrient quality (more energy-dense and less nutrient-rich.)

Telehealth Weight Loss Program for Breast Cancer Survivors

This is a single-arm longitudinal group to examine patient-reported outcomes, body mass and mammographic density changes pre- and post- weight loss intervention of breast cancer survivors using video conferencing telehealth visits.

Adaptations of Exercise Energy Metabolism in Response to Weight Loss in Healthy Normal Weight People

More and more normal weight people are dieting in the general population. The NUTRILEX study aims to better understand the physiological adaptations in response to weight loss in healthy normal weight individuals. After an inclusion visit to verify the eligibility criteria of the subjects, they will complete a "T0" control session. The subjects will then have to complete two phases. The first transversal phase consists of 4 randomized sessions with lunch ad libitum after a physical exercise: i) a control session (no exercise, CON); ii) an exercise session at initial body weight (BWT0); iii) an exercise session with a simulated weight loss of 3% performed on an anti-gravity treadmill (BW-3%) and; iv) an exercise session with a simulated weight loss of 6% performed on an anti-gravity treadmill (BW-6%). During the second longitudinal phase, the participants will perform a dietary rebalancing and a slight caloric restriction (dietary intervention) in order to induce a weight loss of 6% of their initial body weight. Subjects will then perform an exercise session after losing 3% (T1) and then 6% (T2) of their initial body weight.

Effects of FOR-Care Model on Preventive Medicine

This study aims to address the prevalence of undiagnosed hypertension and diabetes by assessing the impact of the FOR-Care model on preventive medicine. The model focuses on improving the documentation of blood pressure, height, and weight in outpatient settings. Through a cluster randomized trial at National Taiwan University Hospital, clinics will either implement the FOR-Care model or continue with usual care. The trial will evaluate the effectiveness of the intervention in documenting these measurements and its impact on diagnosing hypertension and diabetes. The outcomes will provide valuable insights into enhancing preventive medicine and improving care for chronic diseases.

Addressing Weight Bias Internalization to Improve Adolescent Weight Management Outcomes: Randomized Pilot Trial

Weight stigma and weight bias internalization (WBI) are common among adolescents at higher weight statuses. WBI is associated with negative physical and mental health outcomes. The current study aims to test an intervention for weight stigma and WBI combined with an evidence-based adolescent weight management program. Eligible adolescents (13-17) will be assigned by chance to one of two groups: 1) a 4-week intervention focused on weight stigma and WBI followed by a 16-week behavioral weight management program; or 2) a 4-week health information control (to include non-weight-related health promotion topics such as smoking and skin cancer prevention) followed by the same 16-week weight management program but without the WBI and weight stigma content. Study outcomes will be assessed at the 4-week and post-treatment (20 week) timepoints.

Health Effects of Substituting Sugary Beverages With Artificially-sweetened Beverages or Water

Sugar-sweetened beverages (SSBs) contribute an alarming \~7% of calories in the US diet among adults, making SSBs the single largest source of added sugar. However, whether artificially sweetened beverages are a healthful alternative for reducing SSB intake among habitual SSB consumers is unknown. Therefore, the investigators will conduct a 4-arm randomized diet intervention trial to test the effects of substituting SSBs with calorie-free alternatives on body weight and health, among habitual SSB consumers with overweight/obesity.

Pilot Study of Isocaloric Time Restricted Eating on Ketone Metabolism and Immunoregulation

Background: Time restricted eating (TRE) is a form of fasting in which a person eats only during a set window of time, which is usually between 4 and 10 hours each day. Researchers want to know more about how TRE may affect health. Objective: To learn how TRE affects women with different body sizes. Eligibility: Healthy women aged 18 to 50 years. Design: Participants will have 2 visits: 1 screening visit and one 5-day stay in the clinic. Participants will fast before both visits. They will have a physical exam with blood tests. They will talk to a nutritionist about the foods they eat. They will lay under a clear hood for up to 45 minutes during a test that measures how many calories they burn while resting. Participants will keep a food diary for up to 7 days before their clinic stay. They will apply a continuous glucose monitor the day before they go to the clinic. This is a device that attaches to the skin of the stomach. They will wear this device throughout their clinic stay. All meals will be provided during the clinic stay. Participants will follow TRE on 3 days. They will answer survey questions and have tests during their stay, including: * DXA (dual energy X-ray absorptiometry) scan. Participants will lie on a padded table. Their body will be scanned to measure how much muscle, bone, fat, and other tissues they have. * Stable isotope tracer study. Small amounts of sugar and other substances will be given through a tube attached to a needle inserted into a vein in the arm. Blood samples will be collected.

This study evaluates the efficacy of Satisens®, a dietary supplement composed of plant extracts, in reducing emotional eating and sweet cravings in healthy adults. The study will analyze hormonal, neurotransmitter, and inflammatory markers to understand the underlying mechanisms.

Serial Assessment of Body Fat Accrual in Very Preterm Infants

Despite evidence that both rapid weight gain and excessive body fat accrual are associated with overweight and obesity, usual neonatal care of preterm infants does not include assessment of body fat accrual. The study hypothesis is that identification of early changes in infant body composition (i.e. amount of fat mass and fat-free mass) reduces % body fat at 3 months of age.

GLP-1 Medication & Behavioral Health Programs on Weight & Metabolic Outcomes: FLOURISH and THRIVE Prospective Cohort Study

This research program includes two coordinated prospective studies (FLOURISH and THRIVE) evaluating the real-world effectiveness of Noom's digital health programs on weight, cardiometabolic biomarkers, physiological health indicators, and program engagement. FLOURISH is a 6-arm prospective cohort study comparing an Education-only control, Noom Weight, standard-dose compounded semaglutide, microdose compounded semaglutide, standard-dose tirzepatide (Noom Plus), and microdose tirzepatide (Noom Plus Microdose). THRIVE is a nested 2-arm prospective study comparing a Proactive Health program to a Noom Free Tier control. Participants complete monthly surveys, remote biomarker collection (Tasso device), connected-scale weigh-ins, and in-app biometric assessments (FaceScan, BodyScan). Microdose and Free Tier arms also use wearable fitness trackers. Primary outcomes are changes in cardiometabolic biomarkers, weight, body composition, and GLP-1 side effect profile. Total N = 2,310; 24-month duration.

Development of PI-ML Algorithm for Prediction of the Real-time Risk for Developing Pre-diabetes

In this prospective, non-randomized, monocentric study, data will be collected from otherwise healthy individuals with overweight/obese grade I to increase data availability in the pre-diabetes field (impaired glucose intolerance), and to validate the outputs of an algorithm for the "physics-informed machine learning (PIML)" designed to estimate the real-time risk of prediabetes. Each participant will take part in the study for 4 months, including 3 onsite visits. During the screening visit, participants' eligibility will be determined by checking the inclusion and exclusion criteria after detailed information and obtaining informed consent by the investigator. Blood will be withdrawn for exclusion of existing prediabetes/diabetes at the fasted state. For women in reproductive age, a urinary pregnancy test will be performed. After getting the results of blood tests (glucose and HbA1c), participants will be asked to participate in study. On the visit 1, eligible participants will arrive at the study centre in a fasting state. Blood samples will be collected and participants will get vials and instructions for collection of stool and urine samples. Anthropometric data, lifestyle habit (cigarette, alcohol consumption) and family history will be collected. A 6-minute walking test to determine VO2 max will then be performed. Lap counts and time will be manually recorded using a sports watch. The Polar H10 heart rate monitor chest strap will be used to record heart rate (HR) throughout the test. To measure resting HR and heart rate recovery (HRR), participants will be asked to sit still for 5 minutes before the walking test and for 2 minutes after the test. Participants will receive a blinded Abbott Libre Pro glucose sensor, which they will wear for the next 14-days. Further, participants will be provided with a Fitbit Charge 5 health and fitness wristband. For validation purposes some part of study participants will be kindly asked to test newly develop wrist-worn device (EDIBit). With the help of 24-hour food recall, study subjects will be trained by medical staff on how to correctly enter their food intake in the Study app for completion of digital 3-day food diaries. They will be asked to fill in the diaries for 3 days after study visit1 and 3 days before study visit2. They will also receive a food frequency questionnaire during visit1. The second study visit will run nearly identical to study visit1 (except for food frequency questionnaire which will be omitted). During this visit, participants will receive information sheets on physical activity and dietary recommendations. The third and last visit will run nearly identically to the study visit2, except that no new glucose sensor will be inserted and also stool samples will not be collected.

The Effect of an Oral Nutritional Supplement on the Nutritional and Health Outcomes of the Elderly

I am conducting this research to find out if a peanut based food that is ready to use would improve the nutritional and health outcomes of the elderly when they consume it daily for 12 weeks. Eligible participants will be assigned randomly to any of these 2 groups. 1. To consume the food once a day in between meals in addition to their usual food for 12 weeks (3 months) or 2. A control group that will not be given the food. Measurements such as weight, blood pressure and the hand grip strength will be taken at the certain points of the study. A sterile needle will be used to draw about 5 ml of venous blood (from the arm) at the beginning of the study and after 12 weeks. Analyses would be carried out on the blood to know if the food has made an impact on serum albumin, ferritin, haemoglobin and cholesterol. If the findings of the study are favourable, it would provide insights for a larger randomized controlled trial that could establish the efficacy of a locally produced peanut based food for the feeding of the elderly.

Breastmilk and the Link to Overweight/Obesity and Maternal Diet in the Mother-breastmilk-child Triad

The prospective 5-month follow-up study will involve 150 mother-infant dyads grouped based on maternal baseline BMI category (normal weight, overweight, obesity). The investigators plan 3 study visits (1, 3, and 6 months postpartum) with analysis the following parameters and outcomes: 1. maternal anthropometry and body composition; 2. maternal dietary intake and dietary patterns (with results of biomarker-based validation); 3. maternal status of lipophilic antioxidants, selected vitamins, and fatty acids profile that may be related to adipose tissue metabolism, inflammation, and cardiometabolic status; 4. maternal metabolomics, adipokines, insulin, selected biomarkers of inflammation, altered glucose metabolism, and oxidation; 5. breastmilk composition assessed by systemic approach (macronutrients, fatty acids profile, lipophilic antioxidants, adipokines, hormones, immunological profile, and preliminary lipidomic analysis in part of the study group); 6. infant growth trajectory, body composition, urine metabolomics, and biomarkers of oxidative stress. Additionally, maternal and infant stool, buccal swabs, and human milk samples will be banked for further microbiome analysis studies.

The Effect of PIOMI and Chronobiological Nutrition on Readiness for Feeding, Full Transition to Oral Feeding and Body Weight

This is a randomized controlled experimental study evaluating the effects of oral motor intervention and chronobiological approach to feeding model applied to preterm infants on feeding readiness, transition to total oral feeding and body weight.

LiPO Teen (the Lifestyle in Pregnancy and Offspring Teenagers

The study is a follow-up of a Randomized Controlled Trial (RCT) performed in 2007-10 - the "Lifestyle in Pregnancy" LiP study. The LiP study included 360 pregnant women with BMI ≥30 kg/m2 from Odense University Hospital and Aarhus University Hospital. The women were randomized to intervention with low-calorie diet and physical activity from gestational age 10-14 in pregnancy and until delivery - or to a standard care control group. The objective of the LiPO-Teen project is to perform a clinical follow-up study of the eligible 301 mothers who completed the trial until delivery with a liveborn child, and their 14 year-old offspring. The overall ambition is to understand whether lifestyle intervention in pregnancy prevents obesity and its complications across generations, with a specific focus on modifiable factors.

Multivariate Biomarker Study for Sarcopenia in Heart Failure

In the United Kingdom, heart failure (HF) affects about 900,000 people with 60,000 new cases annually. Up to 60% of people living with HF also experience sarcopenia, known as loss of muscle mass and strength. Sarcopenia contributes significantly to low physical capacity and exercise intolerance and worsens the prognosis of the disease and quality of life. In comparison to primary sarcopenia (age-related sarcopenia), secondary sarcopenia occurs if other factors, including malignancy or organ failure, are evident in addition to aging. Secondary sarcopenia is highly common in patients with heart failure (Sarc-HF) (prevalence is 35%-69%), and has a significantly negative impact on exercise capacity, weight-adjusted peak maximal oxygen consumption, left ventricular function, and re-hospitalization rates and mortality. In this integrated study of NHS patients with HF, the investigators aim is to identify the underlying mechanisms of muscle weakness in HF utilizing including body composition, circulating metabolites (metabolic profile), and functional tests for (1) early detection of otherwise subclinical HF, (2) diagnostic assessment of clinically manifest HF-sarcopenia, (3) the risk stratification of subjects with a suspected or confirmed diagnosis, and (4) selection of an appropriate therapeutic intervention.
