Gaining

I'm currently 130kg, but my goal is 180kg, a new fast food restaurant opened near my worksite and I thought about going there for lunch everyday, is it a bad idea?

Health wise, you will probably be fine. The question is if your wallet will be fine too.

This sounds like a wonderful idea

Thanks, then I'll start tomorrow, probably every lunch will be 4000 calories ahah.
I hope to get fatter a bit faster.

Speaking from experience it’s expensive and effective 😅

I wasn’t a huge fast food eater but when I was intentionally gaining I couldn’t get enough of fast food. I actually craved it. I felt kind of guilty at times but I was eating a lot of fast food at least two of my meals per day for several months. I was not only surprised at how much I could now eat when I ordering at the fast food spots but how fat and out of shape I got during this time.

Not the healthiest but it will blow you up!

I did it myself for a good 4-5 months earlier this year. Three times a week I'd go eat fast food as an additional meal (on top of my normal eating schedule).

I usually went for a calorie bomb of 4000-5000 calories of fast food and sometimes topped up with 25cl of heavy cream (since there conveniently is a grocery store right next to the fast food place).

But the bill quickly ran up to 25 euros each time, so easily 50-75 euros a week hence why I stopped.

I did gain nearly 20 kilos in those same 4-5 months tho, it's not the most effective for its money but it definitely worked xD (and was very tasty). I also loved how my orders grew from 2000 calories at first to 4500 calories now. First I added some sides, then a shake, then another burger and eventually I just started ordering 2 menus with those extras still lol.
