The First 1,000 Days Program: Maternal-Child Obesity Prevention in Early Life

The First 1000 Days (conception to age 2) is a crucial period for the development and prevention of obesity and its adverse consequences in mother-child pairs and their families. The overall aim of the First 1000 Days program is to work across early-life systems to prevent obesity, promote healthy routines and behaviors, address social determinants of health, and reduce health disparities among vulnerable children and families at community health centers in the Boston, MA area. The study aims to simultaneously implement and evaluate an obesity prevention program across early life systems to reduce the prevalence of obesity risk factors within racial/ethnic minority families, close the gap in maternal-child health disparities, and assess and address social determinants of health.

Mitochondrial Remodeling After Exercise

Regulation of mitochondrial health in overweight and obese individuals may be impaired. The purpose of this study is to identify impairments in regulation of mitochondrial health within skeletal muscle and to determine if short-term exercise training (2-weeks) can reverse such impairments. The investigator's hypothesis is that pathways that serve to degrade poorly functioning mitochondria in overweight and obese individuals are down-regulated, but that short-term exercise training can restore these pathways to improve skeletal muscle mitochondrial function.

Feasibility and Preliminary Efficacy of a Reverse Diet as a Novel Weight Loss Maintenance Strategy for Weight-Reduced Adults With Overweight/Obesity

The purpose of this project is to test, for the first time, a reverse diet in adults with current or prior overweight/obesity (Ow/Ob). Weight-reduced adults with current or prior Ow/Ob will be randomized to a reverse diet or "standard care" control (CON) intervention for 12 weeks. Eligible participants will have lost >10% body mass. The reverse diet group will receive personalized caloric intake goals, increasing 2-3%/week. The CON group will receive standard weight maintenance recommendations with matched contact. At baseline and week 12, resting energy expenditure (REE), body mass and composition, subjective appetite, and food intake behaviors will be evaluated. In addition to the pre- and post-intervention measures, body mass and adherence to reverse diet will be monitored weekly.

Time-restricted Eating in Morning Chronotype

Overweight and obesity are highly prevalent conditions worldwide, despite active research of new interventions over decades. Current interventions include medications or bariatric surgery, but these approaches cannot be used in all patients and require clear indications and a close multidisciplinary management. Therefore most patients and physicians rely on lifestyle interventions, focusing on a balanced diet and physical exercise. Recent studies have uncovered that energy metabolism is also regulated by circadian rhythms, which depend on spontaneous diurnal oscillations of the central clock, retinal sensing of ambient light, and daily feeding-fasting cycles. The chronotype has an influence on behavioral patterns, where some people describe that they are more alert in the morning or in the evening: The morning or evening chronotypes, respectively. However, in modern societies, many people are exposed to external cues in misalignment with their circadians clocks. The mismatch between the individual chronotype and the social/work life can lead to metabolic disorders. Time-restricted eating (TRE), i.e. energy intake limited to certain windows of time without restricting calories, is an appealing approach because it proposes to realign the circadian clocks with external cues provided by the timing of food intake, thus leading to better metabolic outcomes. The investigators speculate that the TRE intervention needs to be personalized to reach efficacy in a broader population. To tailor the TRE intervention to each individual and harmonize their eating patterns in accordance to their chronotype, the investigators plan to test early TRE vs. late TRE vs. active control in overweight and obese individuals with morning chronotype.

Effects of a Physiotherapist-delivered Dietary Weight Loss Program in People With Knee OA Who Have Overweight/Obesity

The aim of this randomized controlled trial is to evaluate the effects of a physiotherapist-delivered dietary weight loss program on clinical outcomes among people with knee osteoarthritis (OA) who have overweight or obesity. The primary hypothesis is that a physiotherapist-delivered dietary weight loss plus exercise program will be more effective in achieving weight loss than a physiotherapist-delivered exercise program alone. Approximately 6-9 physiotherapists in Melbourne, Australia will be recruited and trained in weight management for OA patients, as well as trained in how to deliver the specific study interventions. The same therapists will deliver the intervention in both arms of the trial. 88 participants with knee OA will be recruited from the community and randomized into one of the two arms a) diet plus exercise intervention or b) exercise intervention alone. Participants in both groups will be asked to attend 6 consultations with the physiotherapist over 6 months. Questionnaire and laboratory-based outcome measures will be completed by participants at baseline and at the end of the 6 month intervention period. A biostatistician will analyse blinded, de-identified data.

Novel Executive Function Training for Obesity

Currently, the best behavioral treatments for obesity only work for 50% of adults, and of those who initially succeed, most do not maintain their weight loss. One reason for this failure may be due to neurocognitive deficits found among individuals with obesity, particularly related to executive function, which make it difficult for these adults to adhere to treatment recommendations. The proposed study aims to develop a Novel Executive Function Treatment (NEXT), which when administered prior to the behavioral treatment, could help improve outcomes by addressing the neurocognitive deficits in adults with overweight or obesity.

Gene-diet Interactions on Body Weight Regulation and Lifestyle Parameters.

Increased body weight leading to the development and the establishment of overweight and obesity, has a growing detrimental effect on overall health status and quality of life. Latest research has been focusing on the direct influence of dietary habits on body weight regulation and its synergistic effect with genetic predisposition. The synergistic effect of genetic makeup and dietary habits constitute a major contributing factor, specifically in its manifestation on parameters of the cardiometabolic profile of individuals with elevated body weight. In this context, the aim of the present study is to investigate the effect of two hypocaloric diets with different macronutrient content (a high-carbohydrate/low-fat and a high-protein one) on the body weight loss of an overweight and/or obese adult, Greek population. Moreover, the study aims to explore gene-diet interactions between obesity and weight loss- related target genes and adherence to the proposed dietary schemes. It will further examine influences of the aforementioned factors on body composition, anthropometric indices, such as waist circumference, biochemical biomarkers related to cardiometabolic control and parameters of lifestyle, such as sleep quality and depression. More specifically, 300 participants will be allocated into two groups, following either the high-carbohydrate/low-fat diet or the high-protein diet, for 6 months. Volunteers will participate in three in-person meetings, one at baseline and two follow ups at three and six months after the beginning of the intervention. Anthropometric measurements and collection of blood samples will take place in each meeting. Demographic data and data on family and medical history, dietary habits, adherence to the Mediterranean diet, overall health status and physical activity will be collected at baseline. Participants will be provided with nutritional counselling and support both at the beginning and throughout the intervention. Participants will further report their monthly progress by completing online questionnaires (namely concerning their body weight, overall health status, physical activity and sleep quality), via use of an online assessment tool developed by our team. The effect of the intervention will be evaluated using anthropometric indices, body composition markers and biochemical biomarkers of cardiometabolic control, pre- and post- intervention. Gene-diet interactions will be assessed via genotyping of DNA samples and statistical analyses will take place via statistical packages, such as PLINK v.1.9.

Active You: Feasibility of a Unique Physical Activity Program to Prevent Diabetes and Heart Disease

Individuals who are overweight/obese are more vulnerable to type 2 diabetes (T2D). Current evidence suggests that PA, even without dietary prescription, can be efficacious in preventing T2D. Yet most Americans, especially those who are overweight/obese, are not physically active. Socioenvironmental barriers to physical activity (PA) such as body image concerns and limited access to fitness facilities contribute to the low levels of PA observed in overweight/obese adults. Web-based PA programs have been developed to address these barriers, but the outcomes have been marginal. Qualitative studies suggest that individuals who are overweight/obese prefer PA programs that feature people they can relate to especially in body size, fitness status and age. Previously, the investigators have included these preferences in a technology-based Physical Activity for The Heart (PATH) intervention that leverages open source platforms, such as YouTube, to promote PA in any setting. In this application, the investigators propose to test the feasibility and preliminary efficacy of PATH in promoting PA and reducing cardiometabolic risk in adults who are overweight/obese and at high risk of diabetes. In Aim 1 the investigators will conduct a 12-week randomized clinical trial including 52 adults who are overweight/obese and at high risk of diabetes to assess the feasibility and acceptability of PATH. In Aim 2 investigators will examine the trend in PA and cardiometabolic risk change from baseline to post-intervention. This approach is innovative because it leverages open source technologies to provide low-cost, action-oriented PA resources that match the preferences of adults who are overweight/obese. This contribution will be significant because PATH could offer a convenient, enjoyable and scalable program that features "similar others" to promote PA in overweight/obese adults at high risk of diabetes.
