Correction to: Nature Medicine https://doi.org/10.1038/nm.2378, published online 31 July 2011.

In the version of the article initially published, there was an error in Fig. 1a where the “Actin” blot mistakenly replicated the “Akt” blot; the original and revised panels are shown as Fig. 1 below. There was also an error in the caption for Fig. 1b where the text “refeeding after 24-h fast” should have read “refeeding after 18-h fast”.
