I've decided to start eating better in order to get the gains I want, but I'm always too busy to cook the food I need to eat. I'm thinking that the best way is to prepare a ton of food at once and live off of that for a few days. My main concern is how long is certain stuff good in the fridge, particularly chicken breast?
I also wouldn't mind making like a gallon sized protein shake to keep in the fridge, but I recall hearing somewhere that this is not a good idea. It this an OK thing to do, and if so, how long can I expect this to be good for? (water, protein powder, heavy cream, strawberries).
