Brief Summary:
Many teenagers do not get enough sleep. Obesity and diabetes are increasing in teenagers as well. This study plans to learn more about sleep and insulin resistance (insulin not working) in teenagers, and how these things may be related depending on sleep. This is important to know so that the investigators understand how sleep may play a role in health conditions like extra weight gain (increased food intake and less physical activity) and diabetes. To answer this question, the investigators plan to enroll teenagers who get <7 hours of sleep on school nights and measure changes in insulin sensitivity and dietary intake after a week of typical sleep (sleeping on their normal school schedule) and a week of longer sleep (spending 1+ hour longer in bed each night).

Arm Intervention/treatment
No Intervention: Typical Sleep
All participants will sleep for 6 nights (Sunday - Thursday) in the home environment per their usual school schedule.
Experimental: Sleep Extension
Participants will be prescribed a sleep schedule that allows them to obtain 1 hour more time in bed compared to Typical Sleep.
Behavioral: Sleep Extension
Participants will be asked to increase time in bed at least 1 hour more than baseline

Primary Outcome Measures :
  1. Change in Insulin Sensitivity [ Time Frame: 2 weeks after Baseline and 7 weeks after Baseline ]
    Insulin sensitivity assessed two times with an insulin-modified intravenous glucose tolerance test.

  2. Change in Sleep Duration & Timing [ Time Frame: At Baseline, 1 week after Baseline, and 6 weeks after Baseline ]
    Assessed three times with a wrist-worn Actigraphy

  3. Change in Physical activity [ Time Frame: At Baseline, 1 week after Baseline and 6 weeks after Baseline ]
    Assessed three times with a triaxial thigh-worn ActivPal

  4. Change in Dietary Intake [ Time Frame: 1 week after Baseline and 6 weeks after Baseline ]
    Participants will be asked to complete diet diaries two times for 3 days during each sleep condition (prior to each overnight assessment), listing all food and drink consumed, estimated portion size, and timing of consumption.
