Update: he gained a little again, but he still thinks I prefer a guy with 6 packs bases on the fact that in the past I was with this type of guys. I don't know how to make him believe me I don't want him to have abs

I mean this kindly, but men can be a little obtuse. You can drop obvious hints, but they often miss it. You gotta be direct and clear.
Tell him you prefer him with more cushion. Show him how horny his fat makes you. If you can cook, feed him and offer him seconds or thirds. Then when you guys have sex, show exrra appreciation towards his softer bits.

As I said before, I think it will be a little weird to be direct with him about this. I don't know if he even knows about this kind of fetish so I don't feel comfortable to tell him yet.
Anyway, it looks like things are getting better. He started eating more even when I don't eat (sometimes he tries to convince me to eat more too, but even if I say no, he still eats a lot). Also, he weight himself yesterday and he just said he gained weight, without adding something like he wants to lose it again. For the next meal he ordered 4 burgers so it didn't looked like he has any intention to lose weight again (in the past when he told me he want to get abs, he used to order just one).
I am glad things are moving along for you. But let me clarify some things.
Liking bigger people doesn't mean you have a fetish. There are a lot of people who prefer or like thick, chubby, or even fat people without it being a kink or fetish to them. Telling your bf that you like him with a bit of padding isn't the same thing as telling him you have a fetish.
For example, a lot of people where I live like bigger people. No one thinks anything of it. It's no stranger that liking tall men or women with red hair.
You will notice nothing I said to do involved you admitting you have a fetish. And if he presses you for an explanation, you can say what most women I know saw when asked why they like fat guys. That you've realized you prefer a man that likes to have fun, is nice to cuddle, and isn't obsessed with his looks.
