What do  you think about throwing away my wife's sweets because she's gotten fat?
Why would you throw away her sweets?
She is too fat and has a muffin top.
If you are concerned for her weight you should tell her nicely. You should not dispose of other people property because you want to.
She's my wife, I should be able to complain about her belly fat.
If you love her you should be accepting of small flaws. If you're worried about her health tell her that, but if it's just because you don't like the way she looks that's not very nice.
