TL;DR: Regular activity breaks were more effective than continuous physical activity at decreasing postprandial glycemia and insulinemia in healthy, normal-weight adults.

TL;DR: Daily supplementation of vitamin D3 was more effective than D2; however, the functional consequence of the differing metabolic response warrants further investigation.

TL;DR: Prolonged sitting results in moderate elevations in postprandial glucose and insulin responses when compared to sitting interrupted with activity breaks, and the magnitude of the reductions in glucose, insulin or triglyceride response was not modified by the intensity of the activity breaks.

TL;DR: The pooled results of studies suggest that energy expenditure exerts most of its influence on fasting triglyceride concentrations rather than on the incremental change in triglycerides seen following meal consumption, which seems more likely thatEnergy expenditure is one component of a multifactorial list of mediators that may include local muscle contractile activity, and other yet to be elucidated mechanisms.

TL;DR: Meta-analysis of data from prospective cohort studies showed small, inconsistent and non-significant associations between sedentary behavior and body weight.
