Lol, I was like that not long ago. Set out on a shopping trip to change my lifestyle etc., and I just stood in the middle of the grocery store completely blank. After a few weeks of repetitive trips, and refining the list, I eventually got to the point where I could mix it up weekly, without seeing a variation in results.
But like the other doods said, carbs like potatoes, rice cakes, brown rice, pasta, oats etc. Lotsa veg (green veggies ftw), and lean meats like chicken fillets, lean steak , tuna etc. Those are the basics.
Dont forget peanut butter and some form of nuts
