Weight Discrimination in Texas?

In the Navy, we have to meet weight standards. It is not hard, provided you work out and eat sensibly. As well as make healthy lifestyle choices. Recently, a Texas hospital started enforcing weight standards during its hiring of new employees:

What some call concern over weight in the workplace–and others call weight discrimination–has been around for years, but a Texas hospital has stepped up the fight.

Citizens Medical Center (Victoria Texas), Weight Discrimination

Citizens Medical Center in Victoria, Texas recently instituted a policy of refusing to hire anyone with a body mass index of more than 35, which means a 5-foot-10 man who weighs 245 pounds would have a BMI of over 35, the hospital’s cutoff.  A 5-foot-2 woman would be over the cutoff at 195 pounds.

Is this legal? I think at a health-care facility, they should enforce standards. And the ones quoted above do not seem impossible to meet. I would imagine the work there to be physically strenuous. No?
