How honest should you be with your friends?

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?”
What do you think?
