What this trial studies
This study investigates the relationship between sleep patterns, dietary habits, and physical activity in adolescents, focusing on the differences between 'Morning Larks' and 'Night Owls'. By extending sleep duration through earlier bedtimes for both groups, the researchers aim to clarify why sleep extension has varying effects on caloric intake and glycemic load. The goal is to identify mechanisms that could inform obesity prevention strategies tailored to different chronotypes. The findings could lead to targeted public health interventions to improve adolescent health outcomes.
Who should consider this trial
Good fit: Ideal candidates for this study are healthy adolescents aged 14-18 who do not have obesity or sleep disorders.
Not a fit: Patients with obesity, sleep disorders, or those on medications affecting sleep or weight may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to effective strategies for preventing obesity and improving long-term health in adolescents.
How similar studies have performed: Previous studies have shown promising results in sleep extension impacting dietary habits, but this specific approach focusing on chronotype differences is relatively novel.
Eligibility criteria

Inclusion Criteria: Healthy adolescents (any sex, gender, race, or ethnicity) aged 14-18 years, inclusive Exclusion Criteria: 1.

Intellectual disability (aka mental retardation) 4. Symptoms of insomnia, obstructive sleep apnea or periodic limb movement disorder, which could mask the effects of the sleep manipulation. 5. Work or other obligations that require bedtime later than 9:30 pm or waking prior to 10 am (earliest bedtime and latest rise time possible during sleep extension) during the final week of the study, or other scheduling obligations that preclude participation. 6. Daily consumption of \>1 coffee or "energy drink" or \>2 caffeinated sodas. 7. Currently diagnosed neurologic illness, history of seizures, or history of head injury resulting in loss of consciousness \>1 min. 8.
