Food insecurity and weight‐loss efforts among a nationally representative sample of US adults with higher weight

Objective The objective of this study was to examine the prevalence of food insecurity among a nationally representative sample of US adults who were attempting weight loss, as well as the associations of food insecurity with weight‐loss strategies. Methods This study included adults with BMI ≥ 25.0 kg/m2 who were intentionally trying to lose weight within the past year from the 2017 to March 2020 data cycle of the National Health and Nutrition Examination Study.

In unadjusted models, participants with food insecurity were more likely to use unhealthy weight‐loss methods (e.g., skipping meals, taking laxatives or vomiting) and less likely to use healthy methods (e.g., exercising, joining a weight‐loss program; p
