Cant gain weight

C

So I’ve been struggling to gain weight for awhile now. I lost a ton due to stomach issues. I ended up figuring out I can’t do gluten anymore. I think my metabolism reset because I can not seem to gain any weight back now.

I stick to plenty of protein at least for meals and keep lots of junk food on hand too. I do protein shakes sometimes. I just get weird about what kinds I drink. I snack all day long too!

Idk what else to try
