TL;DR: A single night of fragmented sleep, resulting in reduced REM sleep, induced a shift in insulin concentrations, from being lower in the morning and higher in the afternoon, while GLP-1 concentrations and fullness scores were decreased, which may lead to increased food intake and snacking, thus contributing to a positive energy balance.

TL;DR: The main effect of circadian misalignment, either phase advanced or phase delayed, is a concomitant disturbance of the glucose-insulin metabolism and substrate oxidation, whereas the energy balance or sleep is not largely affected.

TL;DR: Fragmented compared with nonfragmented sleep induced reductions in the most important sleep phases, which coincided with elevated AEE, physical activity, exhaustion, and sleepiness, which may predispose to overweight.

TL;DR: A reduced sleep duration, quality sleep and rapid‐eye movement sleep affect substrate oxidation, leptin and ghrelin concentrations, sleeping metabolic rate, appetite, food reward, hypothalamic‐pituitary‐adrenal (HPA)‐axis activity, and gut‐peptide concentrations, enhancing a positive energy balance.

TL;DR: It remains to be demonstrated whether body-weight management and body composition improve during an intervention concomitantly with spontaneous sleep improvement compared with the same intervention without spontaneousSleep improvement.
