Recently, there has been a lot of discussion about carb intake and insulin's effect on fat storage, so I thought I would post this study.
Basically, the study shows how varying macro ratios can lead to different results in terms of insulin signaling in muscle or adipose tissue.
The group fed a high carb:low protein meal had significantly greater insulin signaling in fat tissue. Whereas, the group fed a Moderate carb:High protein meal had significantly greater insulin signaling in muscle tissue and little in adipose tissue.
This suggests that the ratio of protein:carb in a meal plays a major role in the partitioning of those nutrients in the body.
