Guys, she dieted for 6+ months, it's just giving the context that he hasn't seen her for 3 of those months so it's to be assumed that he's only seen her at the halfway point. I don't know much about fitness to know what would be considered extreme (though I do think it's supposed to depend on the person and their body type, right? Every person's dna being unique and all that.), so it's still probably not a good rate for weight loss, but it at least wasn't all in just 3 months
