High melatonin concurrent with carb intake (think late-night dinners) impairs glucose tolerance due to insulin secretion defects, especially in MTNR1B G-risk allele carriers.

New study by Drs. Sarah Chellappa, Frank Scheer, & colleagues: Nighttime eating causes internal #circadian misalignment and impaired glucose tolerance in humans, while restricting meals to the daytime prevents both. @ScienceAdvances @BrighamResearch https://t.co/AliEW1uMPo

Drs. Czeisler and @smwrajaratnam, @MarkCzeisler & colleagues found that mental health symptoms were elevated in a Sept. ‘20 nat’l survey compared to pre-#COVID19 levels. Multigenerational caregivers, sexual minorities & those w/ insomnia among highest risk https://t.co/z5GHhpg7oZ

In analysis of 3,362 overweight & obese adults, we found that late eating was associated with cardiometabolic risk factors, higher leptin levels in the morning, and reduced efficacy of a weightloss intervention.

The cover of our March issue depicts a clock, representing circadian time. Mason et al provide an overview of the influence of the endogenous circadian system and its disruption on glucose control in healthy individuals and individuals with T2D https://t.co/HdjLsQKgiX

New study in @PLOSBiology shows that the timing of meals affects how food is oxidized or stored in older adults, which may have implications for the optimal eating habits. https://t.co/zOVoOsDcUX

Our new paper is online! Based on 22 years of data and 732,835 fatal accidents, we show that the spring DST transition increases fatal accident risk by 6%. Risk estimates are higher for mornings and positions further west in a time zone! https://t.co/c7ZEb0HdxR @CUBoulderIPHY

A 3-meal diet consisting of a high-carb breakfast, a lunch, and a small dinner was found to result in #weightloss & improved blood sugar levels in a small group of diabetic patients. Randomized clinical trial published in @ADA_Journals. #ChronoHealth
