NATIONAL doubles chief coach Tan Kim Her, having lost patience with an overweight Hoon Thien How, has asked a nutritionist from the National Sports Institute to help him.
Kim Her felt that the results of Thien How and his partner Tan Wee Kiong could be better if he can overcome his weight problem.
The second ranked national men's doubles have not reached the final of an international tournament despite having partnered each other for more than seven months.
Thien How, whose height is 172cm, weighs between 82kg and 85kg, and this has affected his speed and he tends to struggle when a match goes into three games.
Kim Her said the nutritionist will monitor the 27-year-old Thien How's food intake, body fat and body mass index.
The World No 9 pair have lost to Japan's Hiroyuki Endo-Kenichi Hayakawa three times in the last two months and Thien How's lack of fitness was the telling factor in two of the defeats.
His fitness also came into question when the Malaysian pair lost to China's Hong Wei-Shen Ye and Liu Xiaolong-Qiu Zihan in their last three games in different tournaments.
"Thien How must first overcome his weight problem if they want to achieve better results and become a world class pair," said Kim Her.
"It's his weight that is letting him down especially playing against established pairs.
"I have set Wee Kiong-Thien How the target of winning at least one grand prix title and they should not lose to lower ranked pairs."
Kim Her also didn't spare Wee Kiong, saying the player has a tendency to commit unforced errors when under pressure.
