Commercial Devices Provide Estimates of Energy Balance with Varying Degrees of Validity in Free-Living Adults

Interest in improving accuracy, and replacing self-reports with passive tools when estimating energy balance (EB) using intake (EI), storage (ES) and expenditure (EE)) has led to wide use of commercial devices e.g. Fitbits. A study with free-living adults looked at repeatability, and measurement error of these devices and showed varying degrees of validity when used to estimate EB compared to gold-standard techniques, with EE measures being the most robust and ES the poorest.

Rare Sugars and their Health Effects in Humans: A Systematic Review and Narrative Synthesis of the Evidence from Human Trials

Little is known about the unique physiological and cardiometabolic effects of rare sugars in humans. The objective of this study was to conduct a systematic review and synthesis of controlled intervention studies of rare sugars in humans, using PRISMA guidelines.
