The average "healthy" weight of a 5'7" female is between 120 and 150. You're on the lower end of that and I bet you look fantastic. The only people who should care about your weight are you and any healthcare professional you talk to.

Tell him to go pound sand. The drunken man's words are a sober man's thoughts, right? He's always thought that. He was just loose enough to say it when drinking.

And it's kinda creepy, to be honest. In what world is it normal to sat "lose weight so I can show you off to other men." Why? Why does your weight matter when meeting people... Why would your future scenario with him require you to be overly thin?

Don't let this weirdo give you an unhealthy relationship with food.
