简要总结
The aim of this study is to compare the effect on ketone production of dietary an MCT supplement combined or not with physical exercise in two groups of women (N=10/group), healthy adults and patients with prediabetes. After an evaluation of the metabolism (a 4-hour visit with multiple blood samples) at the beginning of the study, all the participants are taken for one-week the MCT supplement alone follow by a one-week period of taking the MCT supplement in combination with physical exercise. At the end of each period of time, the 4-hour visit for the evaluation of the metabolism is repeated.
