I have collected data from 9 participants during the phases. The first phase the participants were asked to record their sleep throughout the night and fast from the evening before the lab. Blood glucose was then tested for 3 hours following a sugary drink. The second phase the participants were asked to restrict there sleep to 4-5 hours the night before and fast as well. The no participants would then have their blood glucose tested for 2 hours after consumption of sugary drink. The third phase the participants sleep was restricted and while in the lab they were asked to consume caffeinated coffee. Their blood Glucose was tested after the consumption of the sugary drink.

This study will therefore answer two important questions: (1) Does caffeinated coffee intake further impair blood sugar control after acute sleep restriction? And (2) Does caffeinated coffee supress appetite when consumed following sleep restriction? The participants were asked to fill out a 5 question Sprite questionnaire before each blood glucose test.
