Detailed Description
This pilot study included 18 medical residents at two academic medical centers in New York City. All residents who participated in the study were assigned to work a night shift schedule for two weeks, and began the study on the morning prior to their first evening shift. The study subjects were randomly assigned to one of two groups:
- Intervention diet -- consisting of 40% carbohydrates, 30% protein, and 30% fat with 2.4g of long chain fatty acid supplements (n=9) Total calories for males was 1600/day, and 1200/day for females
- Control group -- ad lib diet.
Main outcome measures included:
- weight
- resting metabolic rate
- percent body fat
- lipid profile
- CRP
- fasting glucose and insulin levels
- urinary neurotransmitter levels
- salivary cortisol
- six cognitive tests of memory, attention, and executive function.
