SHIFT-TB: Nutrition Intervention and Evaluation
The goal of this trial is to evaluate a community-based nutrition intervention for adults in Cambodia who are underweight or overweight/obese. This study will examine the effects of the nutrition intervention on participants' dietary diversity and will also assess how acceptable and feasible the intervention is to deliver in the community settings. Health centers were randomly assigned to either the intervention group or the control group. Participants in the intervention group will receive a six-month, community-based nutrition intervention delivered by the Village Health Support Groups, while participants in the control group will not receive it. Researchers will compare the two groups to determine the effect of the intervention on dietary diversity. Participants will complete study assessments at the beginning of the study, at 3 months, and at 7 months.

TREAT to Improve Cardiometabolic Health
Over half of American adults have overweight or obesity and are at high risk of developing type 2 diabetes and cardiovascular diseases. Although caloric restriction has many health benefits, it is difficult to sustain overtime for most people. Time restricted eating (TRE), a novel type of intermittent fasting, facilitates adherence to the intervention and results in weight loss and improvement of metabolism. The investigators propose to examine the efficacy of self-monitoring and TRE (10-h/d) vs. self-monitoring and habitual prolonged eating duration (HABIT) (13 hours/d) on weight loss and body composition, metabolic function and circadian biology, in metabolically unhealthy adults aged 50 to 75 y old, with overweight or obesity. The investigators hypothesize that TRE, compared to habitual long duration of eating, will decrease cardiovascular risk burden.

Cognitive and Behavioral Approaches to Reduce Binge Eating and Excess Weight in Adolescents (Online)
This study will compare a psychological treatment (cognitive-behavioral therapy; CBT-BED) and a lifestyle beahvioral obesity intervention (LBOI) for adolescents who experience binge eating and have overweight or obesity. These treatments will be compared to each other and to a control condition that involves self-monitoring eating and mood using an "app". Participants can be located in most states in the United States. All participation occurs remotely by telehealth. The goal is to learn which approach works best for reducing binge eating and excess weight in this age group.

AI-Driven Metabolic Cohort in Overweight/Obese Chinese Adults
The goal of this observational cohort study is to delineate the five-year dynamic trajectories of metabolic phenotypes in Chinese adults with overweight or obesity, with or without type 2 diabetes, focusing on transition rates from metabolically healthy overweight/obesity to unhealthy overweight/obesity or to type 2 diabetes, as well as the incidence and progression of diabetic complications and cardiovascular events in those with type 2 diabetes and overweight/obesity. Researchers will compare three phenotype groups, namely metabolically healthy overweight/obesity, metabolically unhealthy overweight/obesity, and type 2 diabetes with overweight/obesity, to assess differences in metabolic parameter changes, complication rates, and cardiovascular risk. Participants will use a digital health management platform for data upload and lifestyle support, and will complete comprehensive health assessments at baseline, at 2.5 years, and at 5 years, along with annual light follow-ups.

Understanding the Health Effect of a Bioactive Peptide From Egg: A Pilot Study
Bioactive peptides derived from food proteins show potential for improving human health. One of such promising peptides is namely IRW made from egg white hydrolysate and composed of three peptides. This is a feasibility study to assess the acute effect of IRW in egg white hydrolysate for the management of high sugar and blood pressure. Participants at high risk of type 2 diabetes (T2D) or having T2D will undergo 4 consecutive treatments of 1 day each (randomly), during which they will consume a standardized breakfast with a smoothie containing different protein powders. Each treatment will be separated by a minimum of 1-week. Participants in the healthy control group will undergo 1 treatment only (one day).

A Trial to Learn How Safe AZD9550 Monotherapy and Combined With AZD6234 is in People With or Without Type 2 Diabetes Who Are Living With Obesity and Overweight
AZD9550, previously being developed for the treatment NASH, is a dual GCG and GLP-1 receptor agonist. AZD9550 is now being developed in combination with AZD6234, a SARA, for the treatment of overweight and obesity and its associated co-morbidities. Co-administration of AZD9550 and AZD6234 is currently being evaluated in participants living with obesity and overweight without T2DM in an ongoing Phase 2b study. The purpose of this study is to investigate the safety, tolerability, and effects of increasing doses of AZD9550 monotherapy in overweight and obese participants aged 18 through 65 years living with or without T2DM, and to investigate how AZD9550 is absorbed, distributed, and eliminated from the body (Parts A-D). In addition, the study will investigate the safety and tolerability of co-administration of AZD9550 and AZD6234 in participants living with T2DM with obesity or overweight aged 18 through 75 years (Part E), and safety and tolerability for different titration regimens for AZD9550 in participants living with obesity, but without T2DM, aged 18 through 75 years (Part F).

EMBodied psychOsocial Impacts of Weight Stigma During Pregnancy (EMBODY): A Prospective Cohort Study
The goal of this prospective cohort study is to investigate the contribution of stigma and discrimination due to body size to adverse pregnancy outcomes. We also aim to explore the role of psychological and social factors in this relationship. The specific objectives of this study are: Objective 1: Explore weight stigma as a mediator of the association between BMI ≥30 kg/m2 and adverse pregnancy outcomes. Objective 2: Explore confounding factors not previously considered such as weight cycling, trauma, eating disorders, and internalised weight bias as mediators in the relationship between obesity and adverse pregnancy outcomes. Consenting participants will complete an online survey question at 20-22 weeks' gestation, 29-31 weeks' gestation, 35-37 weeks' gestation, and 6 weeks postpartum. Additional data will be extracted from their EMR.

GRK-Biased Activation Via β2-Adrenergic Receptors in Human Skeletal Muscle
This longitudinal mechanistic physiological study examines biased β2-adrenergic receptor (β2-AR) signaling in human skeletal muscle, with emphasis on G protein-coupled receptor kinase (GRK)-mediated pathways. Participants will receive daily oral dosing of the GRK-selective long-acting β2-agonist ATR-258 for 8 weeks. Muscle biopsies and physiological measurements will quantify GRK-, cAMP/PKA-, and β-arrestin-related up- and downstream signaling, fiber-type specificity, and potential receptor desensitization with repeated stimulation along with functional read-outs, tissue distribution, cardiovascular response and tolerability.

Dietary Strategies for Remission of Type 2 Diabetes
In this project, the investigators will perform a multicenter randomised controlled trial to determine whether advice to consume a moderate, whole food-based low-carbohydrate high-fat (LCHF) ad libitum diet (CarbCount program) can produce and maintain equal remission rates of type 2 diabetes (T2D) as a nutritionally complete very-low-calorie formula diet followed by a energy-restrictive (i.e., calorie counting) diet (DiRECT principles). Within the principles of each approach, the dietary goals and change will be adjusted according to individual needs/capabilities conducive to long-term adherence. Furthermore, the investigators aim to determine whether the rate of diet-induced remission is reflected in/can be predicted by baseline or diet-induced changes in glucose variability (e.g., time-in-range measured by continuous glucose monitoring) and other factors such as anthropometric changes and genetic susceptibility. Each center will also conduct locally-lead standalone mechanistic research, including analyses of intra-abdominal/hepatic fat accumulation, adipose tissue biopsies and/or measurements of energy metabolism. Additionally, changes in medication use, nutritional status, cardiovascular disease risk, as well as adverse events, will be monitored.
