(a) Insulin sensitivity from IVGTTs under conditions of normal sleep (black bars) and sleep restriction (red bars) in N=19 participants. **p<0.01 sleep restriction vs normal sleep. Error bars are SEM. To convert values to SI units, multiply by 0.167. (b) Correlation between the change in nocturnal NEFA levels and the change in insulin sensitivity in n=16 participants. Changes during sleep restriction are expressed as percentage of the values obtained during normal sleep. r= −0.52; p=0.05
