Long-term low-calorie low-protein vegan diet and endurance exercise are associated with low cardiometabolic risk. ABSTRACT Background: Western diets, which typically contain large amounts of energy-dense processed foods, together with a sedentary lifestyle are associated with increased cardiometabolic risk. We evaluated the long-term effects of consuming a low-calorie low-protein vegan diet or performing regular endurance exercise on cardiometabolic risk factors. Methods: In this crosssectional

Results: BMI was lower in the low-calorie low-protein vegan diet (21.3 ؎ 3.1 kg/m 2 ) and endurance runner (21.1 ؎ 1.6 kg/m 2 ) groups than in the sedentary Western diet group (26.5 ؎ 2.7 kg/m 2 ) (p Ͻ 0.005). Plasma concentrations of lipids, lipoproteins, glucose, insulin, C-reactive protein, blood pressure (BP), and carotid artery intima-media thickness were lower in the low-calorie low-protein vegan diet and runner groups than in the Western diet group (all p Ͻ 0.05). Both systolic and diastolic BP were lower in the low-calorie low-protein vegan diet group (104 ؎ 15 and 62 ؎ 11 mm Hg) than in BMI-matched endurance runners (122 ؎ 13 and 72 ؎ 9 mmHg) and Western diet group (132 ؎ 14 and 79 ؎ 8 mm Hg) (p Ͻ 0.001); BP values were directly associated with sodium intake and inversely associated with potassium and fiber intake. Conclusions: Longterm consumption of a low-calorie low-protein vegan diet or regular endurance exercise training is associated with low cardiometabolic risk. Moreover, our data suggest that specific components of a low-calorie low-protein vegan diet provide additional beneficial effects on blood pressure.
