"Abnormal distribution of plasma fatty acids and increased inflammation are prominent features of metabolic syndrome. Aim: to test whether these components of metabolic syndrome, like dyslipidemia and glycemia, are responsive to carbohydrate restriction, by comparing a very low-carb ketogenic (VLCK) diet vs a low-fat (LF) diet."

"Targets E: no restriction Carb: low enough to induce mild ketosis Protein: no restriction Fat: no restriction Intake E: 1504kcal/d Carb: 44.8g/d; 12.4%E Protein: 104.8g/d; 28.1%E Fat: 100.2g/d; 58.9% "
The VLCK diet resulted in profound alterations in fatty acid composition and reduced inflammation compared to the LF diet.
