"[Weight Watchers] taught me portion control and to be conscious of what I put into my mouth," the outspoken McCarthy, 36, tells Shape magazine for its May issue.
Three years ago, McCarthy switched to a gluten- and dairy-free diet, and now a typical day's menu includes egg whites, fish, fresh fruit and veggies. Between meals, she noshes on "those little packets of nuts from Starbucks."
Life with CarreyNow four years into their relationship, the actress likens dating boyfriend Jim Carrey, 46, to "having a front-row seat to the best play you can imagine – every day."
To spice up their relationship, McCarthy taught Carrey to play poker, and the couple have begun hosting poker nights, much to the delight of their friends. Only, she says, "He's got the worst poker face. He jumps up and down when he has a good hand."
Another activity McCarthy is attempting to teach her limber-limbed boyfriend: yoga. "I've seen him eyeing my toned arms," she says. "I give it six months before I find him twisted into a pretzel!"
