The Effects of Intake of Protein From Cod Fillet and Cod Residual Material on Lipid Regulation, Glucose Regulation and Inflammation in Overweight or Obese Adults.

A high intake of fish is associated with positive health effects, including prevention and treatment of chronic non-communicable diseases, such as cardiovascular diseases (CVDs) and type 2 diabetes. These health effects have traditionally been attributed to the omega-3 fatty acids in fatty fish, but recent studies have suggested that also fish proteins may improve biomarkers of metabolic disease. Intake of cod fillet have previously shown beneficial effects on blood lipids, glucose regulation and body composition in adults with overweight or obesity. Health effect of cod residual material from fillet production (i.e., head, backbone, skin, cutoffs and entrails) have so far not been investigated, but residuals from other fish species have shown promising effects on glucose regulation in rats. The main aim of the current study is to investigate the effects of protein from cod fillet and cod residuals on serum lipids, glucose regulation and inflammatory markers in healthy overweight or obese adults.

Complete Health Improvement Program (CHIP) Risk Reduction/Claims Evaluation Project

The project proposes to provide the Complete Health Improvement Program (CHIP) initially up to 25 adult (non-pregnant) Ohio University employees (and/ or their adult family members) with with diabetes / prediabetes, obesity / overweight, hypertension / prehypertension, atherosclerotic cardiovascular disease, or dyslipidemia in an effort to improve self-management and the consequences of biometric factors that can be modified by lifestyle changes. The CHIP program is an educationally based, lifestyle intervention program that aims to reduce healthcare cost, absenteeism, and increase employee productivity. The investigators expect that participants following the programs guidelines will lower their body mass index, cholesterol, reduce blood pressure and blood glucose levels, and therefore help to prevent chronic disease.

Dairy Consumption and Overweight and Obesity in Children and Adolescents: a Meta-analysis.

According to statistics from the European Association for the Study of Obesity (EASO), taking into account the definition of overweight and obesity recommended by the International Obesity Task Fort (IOTF), the prevalence of overweight (including obesity) in European children aged 7 to 17 years is 16-22% and the prevalence of obesity is 4-6%. Some review studies3 and meta-analysis4,5 have reported an inverse relationship between dairy products consumption and the prevalence or incidence of overweight and obesity. However, some methodological issues arise from these analyses. For instance, the combination of studies with different exposures (e.g. full fat milk, total milk) in the total dairy product analysis. Moreover, since the publication of the lasts meta-analysis in 2016, new epidemiological studies evaluating the association between dairy product consumption and overweight or obesity risk have been published. Objective The aim of this work is to systematically review and assess the associations between total dairy consumption and its different subtypes with the prevalence and incidence of overweight and obesity in children and adolescents.

The BMI Project (Body, Mind, Inflammation)

Obesity and chronic inflammation influence the development and progression of many types of cancer. These conditions share several of the same causes, including physical inactivity, poor nutrition, stress, and insufficient sleep. Emerging adulthood (ages 18-25) represents an important developmental period in which to address behaviors and psychological variables that affect both weight status and inflammation. At least 40% of emerging adults have overweight/obesity, and this transition from adolescence to early adulthood is associated with significant increases in fast food consumption, decreases in physical activity, unpredictable sleep schedules, and alarmingly high rates of depression and perceived stress. Despite this high risk for obesity, very few weight loss interventions are designed specifically for emerging adults. Preliminary findings from weight loss interventions targeting this population have shown some promise, but generally produce modest outcomes with less consistent effects than programs in older adults. Depression and stress have been found to interfere with weight loss among emerging adults, and may be in part responsible for poorer outcomes. This proposal will develop and test an Integrated Lifestyle Intervention (ILI) that comprehensively addresses both psychological distress and traditional weight management targets. This novel approach has not been tested before and has the potential not only to enhance weight loss outcomes in this high risk population, but also to produce reductions in markers of inflammation beyond those achievable by weight loss alone.

Neurocognitive Benefits of a Weight Management Program

This study will assess whether weight loss induced through diet and physical activity can change neural responses to high- and low-calorie food images. In addition, it will evaluate whether weight loss can improve neural function when performing the N-back task, a measure of working memory. Findings will address notable gaps in the literature by testing whether a scalable weight loss intervention can help protect and improve neurocognitive functioning and brain health in individuals with obesity. This study will also provide important information about the effects of weight loss on neuroplasticity in brain regions crucial for memory and cognitive functioning, which will help to inform future interventions aimed at promoting brain health.

Project Health: Enhancing Effectiveness of a Dissonance-Based Obesity Prevention Program

This project seeks to improve the effectiveness of a novel dissonance-based obesity prevention program that has reduced future BMI gain and overweight/obesity onset by (a) experimentally testing whether implementing it in single- versus mixed-sex groups, which should increase dissonance-induction that contributes to weight gain prevention effects, and (b) experimentally testing whether adding food response and attention training, which theoretically reduces valuation of and attention for high-calorie foods, increases weight gain prevention effects. This randomized trial would be the first to experimentally manipulate these two factors in an effort to produce superior weight gain prevention effects. A brief effective obesity prevention program that can be easily, inexpensively, and broadly implemented to late adolescents at risk for excess weight gain, as has been the case with another dissonance-based prevention program, could markedly reduce the prevalence of obesity and associated morbidity and mortality.

Effect of a Group Intervention Program Based on Acceptance and Mindfulness on the Physical and Emotional Well-being of Overweight and Obese Individuals

The objective of the present study is to evaluate the effect of a 20-week group intervention program based on acceptance and mindfulness in emotional eating, weight loss, physiological parameters and the level of physical exercise, as well as in the quality-of-life and weight self-stigma of overweight and obese people on the short- and medium-term. Design, participants, and method: A randomized clinical trial comprising a total of 110 overweight or obese (BMI ? 25) participants that are receiving medical treatment at Primary Care Centers, 20-65 years, will be included and randomly assigned to standard program (N=55) or standard + intervention program (N=55). The standard program group will receive the treatment as usual (TAU) that comprises 5 sessions (on a monthly basis) that will include a personalized diet and physical exercise recommendations, while the standard + intervention program group will receive the same TAU plus the acceptance and mindfulness-based group intervention program. At baseline prior to randomization, after the intervention, and seven months after the program has finished anthropometric and body composition data, biochemical data in blood, waist circumference, blood pressure, eating habits, level of physical exercise, general health, emotional eating, quality-of-life, weight self-stigma, experiential avoidance, self-compassion level and mindfulness abilities will be evaluated. It is hypothesized that the integrated treatment of obesity implementing a group intervention program based on acceptance and mindfulness could help to reduce the emotional eating, enhance weight loss, improve physiological parameters, increase the level of physical exercise, improve the quality of life and reduce the weight self-stigma of overweight and obese individuals.

Preventing Weight Gain Among Those Who Decline Behavioral Weight Loss Treatment (STEADY)

To prevent weight gain while overcoming these common barriers to engaging in weight management interventions, we propose an intervention that prescribes self-weighing but does not prescribe changes in diet or physical activity behaviors or require attendance at didactic-focused meetings. The potential of self-weighing to promote weight management is supported both by self-regulatory theory and empirical research. Promoting self-weighing may activate participants' self-regulatory skills, leading to spontaneous decisions to reduce calorie intake or increase physical activity, thus preventing further weight gain. The proposed intervention will also provide individuals with text message-based feedback to promote continued self-weighing and to motivate engagement with evidence-based resources for weight management at a time when they may be more open to using these resources-e.g., after experiencing a small weight gain. The current proposal will investigate the feasibility and acceptability of this low burden self-weighing intervention in order to prepare for a fully-powered, pragmatic randomized controlled trial. We will enroll 40 patients with either obesity or overweight with a weight-related comorbidity and who have declined to participate in a comprehensive behavioral weight management program. Participants will be asked to weigh themselves daily via a "smart" scale that transmits weight data directly to the study team via the cellular network. Every-other week, participants will be sent text messages providing brief feedback encouraging continued self-weighing. Moreover, if a small weight gain is observed, participants will be sent text messages aiming to engage them in commercial or community-based evidence-based weight management resources. In a single-arm design, all enrolled participants will receive the intervention for 12 months and will complete assessments at 3 and 12 months to assess feasibility and acceptability of the intervention and trial design, while weight will be obtained from participants' Electronic Health Records (EHR). We will evaluate our success in meeting pre-specified metrics for trial feasibility and intervention acceptability outcomes, including intervention enrollment, intervention satisfaction, and obtainment of weight data abstracted from participants' EHRs. We will also evaluate the success of the intervention in promoting regular self-weighing and use of evidence-based weight management resources.

Daily Self-Weighing for Obesity Management in Primary Care

Many adults with obesity continue to gain weight even though they do not want to. This project will test the effects of a primary care intervention in which people with obesity receive an electronic scale and recommendations to weigh themselves daily. This will help us understand whether daily self-weighing might be a way to prevent continued weight gain.
