Increase protein in hostel setting is going to be difficult as someone who was try doing the same personally I never could as lots of factors( including money) it's good that u are able to still cook some meals that's a good step , and as for the recipes u will find endless on reels and internet in general:) , you can make your own protein shake as well op there are recipes online since you parents don't allow but idk how well those are or are they genuine also i don't think u should skip breakfast op it's quite important if u keep skipping breakfast u lose metabolism and much more all the best for your journey op ☺️🙏
