Effects of Olive Oil and MLCT on Glycolipid Homeostasis in Patients With Metabolic Syndrome

We conducted a 6-month RCT to evaluate the effects of olive oil and MLCT as cooking oils on glucose and lipid homeostasis in patients with MetS; investigate the changes in lipoprotein subfractions and metabolites using NMR spectroscopy, alongside gut microbiota alterations, to elucidate potential mechanisms; and identify baseline variables associated with the anti-obesity effects of olive oil and MLCT.

Inclusion criteria

Participants eligible for the study were those with a confirmed MetS diagnosis according to the IDF criteria53, aged between 40 and 70, and who reported infrequent consumption of meals outside the home (≤3 times per week)

Exclusion criteria

(i) current breastfeeding or pregnancy; (ii) history of cardiovascular disease, including heart disease, coronary artery disease, stroke, cerebral infarction, viral hepatitis (e.g., hepatitis A or B), chronic kidney disease (estimated glomerular filtration rate [GFR] <60 ml/min), or malignancy; (iii) presence of diabetic ketoacidosis or hyperketonemia; (iv) recent alterations in prescribed medication within the previous 6 months; (v) current use of insulin therapy; (vi) consumption of MLCT in the preceding 6 months; (vii) participation in other clinical research studies within the last 6 months; and (viii) premenopausal women
