greater effects of MCFA associated with lower body weight

Greater rise in fat oxidation with medium-chain triglyceride consumption relative to long-chain triglyceride is associated with lower initial body weight and greater loss of subcutaneous adipose tissue.

All subjects in the study were overweight men. Diets were MCT oil vs olive oil. Lower body weight was associated with greater both energy expenditure, fat oxidation, and fat loss with MCFA.
CONCLUSION:
"These data suggest that shunting of dietary fat towards oxidation results in diminished fat storage, as reflected by the loss of BW and subcutaneous adipose tissue. Furthermore, MCT consumption may stimulate EE and fat oxidation to a lower extent in men of greater BW compared to men of lower BW, indicative of the lower responsiveness to a rapidly oxidized fat by overweight men."
