1. Limiting food intake to daytime hours may mitigate cardiovascular risk factors associated with simulated night shift work.
2. Daytime-only eating prevented changes in heart rate variability and prothrombotic markers. 
3. A daytime eating schedule may help offset some adverse cardiovascular effects of circadian misalignment, potentially reducing coronary heart disease risk. 
4. The study population consisted of healthy, non-shift workers in a controlled laboratory setting, possibly limiting generalizability.
5. Study limitations included a relatively small sample size and a restricted participant age range (18 to 30 years). 
6. Approximately 15% of workers in industrialized countries perform night shift work.
