Report: Phil Kessel has been on a strict diet this summer.

Phil Kessel is apparently taking his next season with the Penguins a little more seriously than he took his time in Toronto.

According to TSN Insider Darren Dreger Phil Kessel has been working very hard during the offseason with former Pittsburgh Penguin Gary Roberts, Roberts has developed his own condition program for pro athletes.

As per Dreger's report Kesse has already shed thirteen pounds in the offseason, something that is likely to have an impact on his on ice performance. Whether that impact will be negative or positive remains to be seen.

At least fans in Pittsburgh know Kessel is taking this oppurtunity seriously.
