Australia's Peter Siddle has 'vegetarian diet' to regain speed ahead of Test series against Pakistan

Australian pacer Peter Siddle has reportedly added five kilos of mass in a bid to regain his bowling speed and says that he can survive the searing heat of the Middle East.

Dropped for the final Test in South Africa earlier in 2014, the country's most famous vegetarian athlete reportedly hit the gym to replace weight and power, he had lost through a hectic nine-month schedule.

Siddle is set to return to the Test side when Australia take on Pakistan in Dubai, armed with pace that had made him a mainstay of Michael Clarke's attack, Stuff.co.nz reported.

The pacer admitted that he was 'fatigued' and 'shot' when his pace dropped in Port Elizabeth.

After coach Darren Lehmann had earlier declared that Siddle was axed because of lack of pace, the fast-bowler altered his training regime and replaced running with a gym schedule, adding that it makes it a little bit easier to maintain weight.

Siddle believes that he put on nearly four-and-a-half to five kilos, adding that it's a 'lot of weight'. He added that he is 'feeling good' and the diet hasn't changed.

He concluded by saying that being non-vegetarian doesn't make a difference at all and added that he watches what he eats.
