Eva Longoria

Eva Longoria says she was unhappy about her weight loss after her November 2010 split from pro basketball star Tony Parker — even though she was getting compliments.

"I was so thin and everyone kept saying how great I looked and it was probably the most unhealthy place I've ever been," Longoria recalls in the latest cover story of Health magazine.

"So it was funny what people would see as 'healthy,'" she says. "In my worst time, people were saying I've never looked better."

The 36-year-old Desperate Housewives actress also discusses the year she spent being a vegan (she calls it her "biggest health regret") and the fact that she previously worked as a personal trainer and aerobics instructor.
