Background: It takes several days to adapt to a high-fat diet. In an earlier study, we observed
a large degree of interindividual variation in the capacity to adapt to a high-fat diet. We
hypothesized that concurrent physical activity would accelerate fat oxidation during an
isoenergetic high-fat diet. Objective: The objective of this study was to determine the effect of
increased physical activity on the ability of young healthy men to increase fat oxidation
during the shift to a high-fat diet. Design: Six young healthy men participated in a …
