Independent effects of the human circadian system and sleep/eating cycles on caloric intake in adolescents vary by weight status Open
Late-day eating is linked to increased obesity risk; however, whether the endogenous circadian system independently influences caloric intake and if this control differs among individuals based on weight status is unknown. Here, we investi…

How Do School Salad Bars Impact Elementary School Students’ Dietary Quality and Energy Intake at Lunch? A Randomized Controlled Plate Waste Investigation Open
Background: Children’s dietary quality is suboptimal, increasing the risk of numerous chronic illnesses. Salad bars (SBs) have potential to enhance children’s nutritional intake within the National School Lunch Program (NSLP); yet, empiric…

Behavioral Intervention that Extends Sleep Duration Leads to Greater Self-Control in School-Aged Children Open
Objective: Short sleep and evening phase preference associate with impaired self-control, yet few studies have assessed the efficacy of sleep extension for improving this behavioral domain. Thus, this secondary analysis of a behavioral sle…

School Nutrition Personnel Perceptions of School Salad Bars before and after COVID-19 Open
Many schools have salad bars as a means to increase students’ fruit and vegetable intake. School nutrition programs experienced drastic changes to the school food environment due to COVID-19. The aim of the current study was to understand …
