My face looks extremely bloated and puffy..is it my diet?

Im a 22 year old guy, 6'3 and went from 158 to 163 pounds over a few weeks, as I'm trying to bulk up and gain weight. But it seems like throughout this attempt my face is bloated and looks like a puffer fish, and I don't like it. I could probably easily blame it on my diet, as most of what i ate to gain some weight was alot of fast food, and some processed foods too like roman noodles and poptarts. I also drink soda sometimes as well. Could it be all the refined sugar and sodium from the fast food thats making my face stay puffy? Should i switch to eating healthy food to gain weight? I feel very uncomfortable and i lack confidence knowing my face is puffy like this
