well with regards to exercise: I absolutely love gardening. It's not something I do "for excerise".
as for eating healthy. It's all about finding some recipes you like: finding that over on the ven diagram between healthy eating and love to eat. of course if you grew up on a completely fast food diet you're body will be way too addicted. I suppose it's like asking a heroin addict to not do heroin everyday: that may feel like torture too.
