Prevalence of hypertriglyceridemic waist (HTGW), which is characterized by abdominal obesity and high levels of triglycerides, was assessed among 6,732 participants of the PREDIMED-Plus trial. Researchers concluded that those who smoked, had a sedentary lifestyle, higher BMI, and higher levels of glucose and lipid profile [total cholesterol, low density lipoproteins (LDL), and triglycerides (TG)] frequently had this HTGW phenotype. In contrast, those who followed the Mediterranean diet (abundant in olive oil), in most cases, did not show this phenotype. These results were independent of total energy intake.
