How honest should you be with your friends?

“One of my best friends since junior high struggles with dating. Once she’s comfortable with a guy, she’ll gain 15-20lbs and around then they’ll break up with her.
She told me about her latest breakup so I told her guys leave her because she lets herself go.
She told me I was insensitive and since hasn’t replied back to my messages.
How do I make it up to her? Was I insensitive?”
