Hindustan Times also quoted a source saying: 

Pakistani players are known to have a fondness for junk food and rich oily dishes when they are not playing for the national team but Misbah has told every player that a log book will be maintained on their fitness and diet plans and anyone found lacking would be shown the door.

Since Misbah's retirement in 2017, the Pakistani cricket team has struggled to keep up with the rest of the world in terms of fitness and otherwise, despite having a young group of extremely talented players.
