MCT Oil for Overweight Management

B

Meta-analysis of 13 RCTs (n=749) found MCTs reduced body weight (0.51 kg), waist circumference (1.46 cm), and total body fat. Acute studies show MCTs increase energy expenditure by approximately 5% versus long-chain triglycerides. A 4-week crossover study (n=24) found MCTs reduced intake by 256 kcal/day.
