I need your ladies help!

I'm starting to feel disgusting and unattractive to my partner (as in no longer feeling happy about my body) I'm in the process of telling him this and am wanting to start eating healthier and exercising, but I wanna do it with him.

What are some great healthy eating diets that are affordable and easy to do?

Eta: my partner doesn't finish till 11:30pm most nights so I don't end up eating dinner till then.
