How Morning and Evening Body Clocks Relate to Meal Timing and Nutrient Intake in Adults

Evening types consumed higher intakes of energy, sucrose, fat, and saturated fatty acids in the evening compared to morning types.

• Morning types generally had higher energy and macronutrient intakes in the morning, except for sucrose where evening types had a higher intake.
• On weekends, the differences in evening energy, sucrose, and fat intakes between chronotypes were more pronounced.
• Evening types had more eating occasions and exhibited more irregular meal times compared to morning types.
• The delayed timing of energy and macronutrient intake among evening types may be associated with unfavorable dietary patterns.
