On Gaga's diet circa May 2009: She was suffering from lack of sleep, perpetual jet lag, and a rigorous, self-imposed diet. "She'd say, 'I can't have that, I can't have that,'" David Ciemny, Lady Gaga's former tour manager says. "She always wanted salads, deli meat and cheese, and hummus and chicken -- that was her big thing, hummus and grilled chicken. If she had something fried, she'd say, 'I totally splurged.'"
Like just about every other famous young girl, Lady Gaga had to keep her weight at a ridiculously low level. "From the first time we met her and measured her and checked her for the final [ensembles], she'd lost twenty pounts," says a costumer who worked with her last year. "She self-proclaimed that she didn't eat for weeks to fit into the clothes."
