![MedicalResearch.com Interview with: Sarah Messiah, PhD, MPH Professor of epidemiology, human genetics, and environmental sciences UTHealth School of Public Health Dallas MedicalResearch.com: What is the background for this study? Response: Given that obesity is a prevalent, serious, complex, chronic, and relapsing disease, and severe obesity is a deepening crisis, it is important to pay special attention to these challenges during the COVID-19 pandemic. This will avoid placing an even greater burden on individuals, health systems, and society in the post-COVID-19 recovery phase. Thus, it is critically important to document, in real time, how socioecological determinants of health are impacting behaviors among those with obesity. Before our study, how the COVID-19 pandemic is impacting weight management, health behaviors, and psychosocial health in particular among people with obesity was unknown. MedicalResearch.com: What are the main findings? Response: A total of 123 patients (87% female, mean age 51.2 years, mean BMI 40.2, 49.2% Non-Hispanic white, 28.7% Non-Hispanic black, 16.4% Hispanic, 7% other ethnicity, 33.1% completed bariatric surgery were included). -Two patients tested positive for SARS-CoV-2 and 14.6% reported symptoms. -10% lost their job since the beginning of the pandemic -25% reported food insecurity in that they sometimes, or always could not afford to eat balanced meals -72.8% reported increased anxiety and 83.6% increased depression since stay-at-home orders were initiated. -69.6% reported more difficultly in achieving weight loss goals -47.9% reported less exercise time and 55.8% reported less intensity -49.6% reported increased stockpiling of food -61.2% reported stress eating -61.2% reported following healthy diet plans more challenging - Hispanics were less likely to report anxiety versus non-Hispanic whites MedicalResearch.com: What should readers take away from your report? Response: In a relatively short period of time, our results show that there have been substantial perceptions in changes in health behaviors among patients with obesity. Our sample described a decreases in positive health behaviors, increases in deleterious behaviors and associated deterioration in mental health. Even though actual COVID-19 disease burden was low (1.7% tested positive for COVID-19 and another 14.6% reported symptoms), the pandemic is having a significant impact on those without infections. The major strength of this study is that it is the first snapshot into how the COVID-19 pandemic has influenced health behaviors for patients with obesity. Prior to the pandemic, it has been reported that Americans consume 20% of their calories from restaurants and that there are worsening disparities in fast food meal quality by race/ethnicity, education, and income. Due to recent economic challenges, patients may be more likely to select cheaper foods, which are often energy dense and nutrient poor. Therefore, even though we found more patients are cooking at home, the type of foods that are being stockpiled are likely to be processed foods due to their longer shelf life. These are associated with greater intake of fat, carbohydrate, and calories, which facilitate greater weight gain when compared to more balanced diets. It is possible Americans may be trading one pattern of low-quality consumption for another by choosing cheaper processed foods instead of eating out. MedicalResearch.com: What recommendations do you have for future research as a result of this work? Response: These results have implications for clinical practice and management of patients with obesity as we now move into post-COVID-19 relief efforts. Due to the increase in obesogenic behaviors related to the COVID-19 pandemic that were found here, it is paramount that healthcare access is not disrupted for patients with obesity. Maintaining these vital services will prevent exacerbating the negative health and economic consequences of excess body weight. This includes access to primary care providers, Obesity Medicine specialists and bariatric surgery programs. In addition to asking about diet and exercise patterns, screening for indicators of mental health, loneliness, financial stressors and behaviors that may influence body weight should be implemented by healthcare teams to combat this problem.

Response: This study is a follow-up study to our previous study where we found that chronic insufficient sleep together with chronic jet lag is associated with adverse changes in metabolism, including increase in blood sugar levels (Buxton et al. Science Translational Medicine, 2012). The present study focuses on the influence of the time of day on metabolism, which has not been investigated in humans independent of the effects of sleep, physical activity and diet.

Response: Intermittent energy restriction is a new popular diet method with promising effects on metabolic function but limited research exists on its effects on improving glycemic control in people with type 2 diabetes.
The findings of our research demonstrate that a diet with 2-days of severe energy restriction per week is comparable to a diet with daily moderate energy restriction for glycaemic control. (more…)

Response: The culinary benefit of chili peppers is known for decades. Previous research works have identified the benefits of chili peppers for treating pain and metabolic diseases. Recently, we have discovered that CAPSAICIN, the chief ingredient in natural chili peppers, triggers the conversion of energy storing white adipocytes into energy expending brown like (Beige or brown in white, BRiTE, cells). This increases thermogenesis and counters high fat diet-induced obesity without modifying energy intake (in other words, without causing appetite suppression).
Our published research clearly demonstrates the expression of capsaicin receptor in the white and brown adipose tissues and activation of these receptors (TRPV1, transient receptor potential vanilloid subfamily 1) by capsaicin underlies its anti-obesity effect. Since capsaicin is pungent, we have developed a polymer coated orally bioavailable formulation of capsaicin. This polymer coating decreases the burst release of capsaicin, which reduces its pungency. Also, the polymer coating sustains the release of capsaicin for longer period of time, which will enhance its (capsaicin’s) bioavailability in the body.

- The benefits of fitness are well know, but it was unclear whether the benefits applied to those with severe obesity. This is even more important give that the health risks associated with severe obesity are exponentially higher than in mild obesity. Fitness in this study was defined as the top 80% of a normal population.This means that unfit is the bottom 20%. In the past, research has shown that this threshold of fitness is associated with the biggest health benefits.
- We see that 40% of individuals with mild obesity are fit, while 11% of those with severe obesity are fit. Individuals with high fitness had no differences in health risk, despite the large differences in obesity (~50-100 pounds). Conversely, those within the unfit group did have significantly higher glucose, blood pressure and lipids with higher obesity levels.
In other words, fitness was able to protect individuals with severe obesity from many of the expected negative health consequences. (more…)

Response: Childhood obesity is an increasing problem worldwide. In the UK, the proportion of children who are very overweight doubles during the primary school years. Furthermore during this period inequalities emerge. At school entry there is little difference in the likelihood of being overweight between groups. However on leaving primary school, children from minority ethnic groups and those from more deprived, compared to more affluent backgrounds are more likely to be overweight. Excess weight in children is linked with multiple health, emotional and social problems. As children spend a lot of time at school, it seems intuitive that they are an ideal setting for prevention interventions.
Although a number of studies have investigated the evidence for school obesity prevention programmes, the results have been mixed and methodological weaknesses have prevented recommendations being made. As a result we undertook a major high quality trial to evaluate an intervention that had been developed in consultation with parents, teachers and the relevant community. The 12 month programme had four components. Teachers at participating schools were trained to provide opportunities for regular bursts of physical activity for children, building up to an additional 30 minutes each school day. There was also a workshop each term, where parents came in to cook a healthy meal (breakfast, lunch of dinner) with their children. In conjunction with a local football club, Aston Villa, children participated in a six-week healthy eating and physical activity programme. Finally, parents were provided with information about local family physical activity opportunities.
We involved around 1500 year 1 children (aged 5-6 years) from 54 state run primary schools in the West Midlands. At the start of the study, we measured their height and weight and other measures of body fat, asked the children to complete a questionnaire about their wellbeing, to note everything they ate for 24 hours, and to wear an activity monitor that recorded how active they were. After this, the schools were randomised to either receive the programme or not. We then repeated the measures 15 and 30 months later.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Obesity and diet-induced diseases, such as cardiovascular disease, have reached epidemic proportions. The United States has offered universal dietary recommendations for decades, but they have been largely unsuccessful in reducing diet-induced diseases. These recommendations are largely built upon population-level data, which examines a large number of individuals and determines the average response to a dietary intervention. However, if there is large variation in responses within a population, then population-level data may be inadequate to improve health across genetically diverse individuals.
Our study used four genetically diverse types of mice to examine how one’s genetics interact with diet to influence obesity and risk factors for cardiometabolic disease. The study compared four popular human diets (American, Mediterranean, Japanese, and Maasai/ketogenic). While all mice suffered detrimental effects from the American diet, the severity of disease varied widely across the types of mice. In comparison, no single diet improved health across all strains, but there was one or more diets that improved health in each strain.
