Our biological clock, or circadian clock controls all levels of physiology that are in tune with daily environmental cycles. Some evidence suggests a relationship between an
individual’s circadian preference and dietary intake but additional research is needed. Circadian misalignment occurs when behaviors (i.e., wakefulness, eating, activity) occur at inappropriate circadian times. However, the relationship between chronotype, social jetlag, and dietary patterns as measured by the Healthy Eating Index (HEI) of non-shift workers has not been fully examined.
This study will take a cross-sectional look into the HEI scores of non-shift work individuals with social jetlag and/or late chronotype and examine their dietary patterns to determine if there a relationship between these factors and body composition. Our overall hypothesis is that a late chronotype and/or individuals with high social jetlag will consume a diet with a low HEI score, greater total calories and have a higher waist to hip ratio.
