Key Takeaway
MCT oil supplementation significantly reduces body weight, BMI, and waist circumference compared to long-chain triglycerides in overweight or obese individuals.
Summary
This systematic review and meta-analysis evaluated the effects of medium-chain triglyceride (MCT) supplementation on weight loss and metabolic markers in overweight or obese populations. The authors pooled data from randomized controlled trials comparing MCT intake to long-chain triglyceride (LCT) controls.
Results showed that MCT consumption led to statistically significant reductions in body weight, body mass index (BMI), and waist circumference relative to LCT controls. The findings suggest that replacing conventional dietary fats with MCTs may offer a modest but meaningful advantage for weight management in individuals with excess body fat.
The meta-analysis also examined metabolic health markers and found potential benefits for lipid profiles and insulin sensitivity, though these effects were more variable across studies. The authors note that MCTs rapid absorption and preferential oxidation over storage may explain their favorable effects on body composition.
