I am struggling with my diet.

I’m a final year med student staying in a hostel, and I’ve been trying to improve my fitness and maintain a high-protein diet consistently. The problem is hostel mess food is honestly pretty bad ,low protein, not very nutritious, and I have limited cooking options.

I’m non-vegetarian.

Wanted recommendations from people who’ve managed fitness in similar situations:

* Affordable high-protein foods that are easy to keep in a hostel

* Good protein brands/supplements that are trustworthy but budget-friendly

* Any easy meals and hacks when you don’t have access to a proper kitchen

Trying to stay fit without spending a fortune since I don't make money yet .Would appreciate suggestions.
