If you're overweight and over 55 with a high risk of heart disease, you're about a quarter less likely to stick with the Mediterranean diet for three years than someone your age who isn't overweight.

Assessment Explanation
The claim uses 'likely to have lower odds,' which correctly frames the relationship as probabilistic and correlational, not causal. It specifies a measurable outcome (Mediterranean diet score ≥10/14), a defined population, and a time frame—all consistent with observational cohort studies. The 23–26% range suggests an effect size derived from statistical modeling (e.g., logistic regression), which is appropriate for this claim type. No overstatement is present, as it avoids implying causation or universal applicability.
More Accurate Statement
“Obese adults aged 55–80 years at high risk for cardiovascular disease are associated with 23–26% lower odds of achieving high long-term adherence to the Mediterranean diet (score ≥10/14) over three years compared to non-obese individuals of the same age and risk profile.”

Abstract P098: The Association Between Obesity Status and Long-Term Adherence to Mediterranean Diet in the PREDIMED Trial
This study found that older, high-risk adults who are obese are less likely to stick to the Mediterranean diet over three years compared to those who aren’t obese — exactly what the claim says.
