Obesity is a health risk characterized by chronic inflammation, and food choices are strongly associated with its etiology. Our objective was to investigate the association between dietary patterns and the healthy eating index (HEI) with the odds of overweight/obesity and related inflammatory markers. Within a population-based case-control study, we collected data and samples from 793 normal-weight and 812 overweight/obese Iranian people (based on either body mass index (BMI) or body surface area (BSA)). Dietary intake and HEI scores were obtained via a validated 124-item food frequency questionnaire. Anthropometric and socioeconomic parameters, as well as blood inflammatory markers, were measured. Participants with higher HEI scores had higher serum high-density lipoprotein-cholesterol (HDL-C) and significantly lower energy intake. Water consumption in the overweight/obese group was significantly lower than in the control group. In the final models using partial correlation and controlling for multiple confounders, there was a significant inverse correlation between HEI and interleukin-4 (IL-4, R = -0.063), IL-1β (R = -0.054), and high-sensitivity C-reactive protein (hs-CRP, R = -0.069). Based on multivariable logistic regression models adjusted for multiple confounders, there was a significant association between HEI as a continuous variable (OR = 0.993, 95% CI: 0.988-0.999) and categorical variable (OR = 0.801, 95% CI: 0.658-0.977) and odds of overweight/obesity across BMI groups. The dietary patterns in the case and control groups however were similar, and we failed to find a significant association between HEI and odds of overweight/obesity based on BSA. Adherence to healthy eating recommendations may be a prudent recommendation to prevent overweight/obesity and keeping inflammatory indicators low.

The worldwide increase in the prevalence of obesity and adiposity-related comorbidities has required a novel approach to cardiometabolic risk mitigation focused on the key mechanistic drivers of disease. The current manuscript presents the case of a 74-year-old male with obesity complicated by coronary artery disease, hypertriglyceridemia, hypertension, nonalcoholic fatty liver disease, obstructive sleep apnea, and type 2 diabetes. Expert panelists discuss optimal diagnostic and treatment strategies focused on lifestyle modifications including dietary interventions such as the Mediterranean dietary pattern, medications that target multiple drivers of disease, as well as procedural options.
