Oh no!
Eat fats! Eat whatever you want, provided that it didn’t have a ton of preservatives dumped on it or were heavily processed. I know Jarvan wrote this already, but I want to re-emphasize this.
Eating healthy doesn’t need to mean eat nothing but chicken breast and broccoli, but it will require some prep on your part and the willingness to cook.
Here’s a link that might help with diet.
I would suggest that you find something that you can eat repeatedly without getting bored.
My dinner, for the most part, used to be a mixture of lean ground beef/ground turkey with a ton of the spices that I enjoy( occasionally spiced up with bacon or some sort of sausage if there’s a sale going on) + some yam/potatoes + steamed broccoli cause it’s easy + store-made kimchi.
I have no qualms about eating out on the weekends, but dinner was pretty much always the above unless I worked very late and didn’t want to cook.
Diet is a habit. So, you need to find some habitual practices that fit with your goals and time commitment. But, once it becomes habit, it needs to stay a habit. Changing your diet for a couple of weeks/months don’t really work.
