If you want a flavorless one, Zone Perfect has a protien shake that is 7g of protien and nothing else. I really like the Ultra Pure Protien shakes that come in a can for ready made ones. Designer whey is a good one that can be used in alot of cooking. You can also get powdered egg whites to mix into things such as shakes or cookig for added protien.

Stay away from Super Red and Super Blue Soy protiens though. They are great in that they have a lot of protien with little fat or carbs, but the taste is nasty.

Regular food wise. Be sure to have protien at each meal to control insulin spikes. Spreading it out like this also helps you get in enough. Get frozen precooke,d tail off shrimp to add to salads for a kick of protien. Peanut butter, cottage cheese, broccoli, tofu, KETO cereals, and other nut butters are all great non meat protien sorces. Red meats, chicken, fish and other meats of course are good sources of protien. Just be careful eating the large preditor fish like tuna too much. Nuts are a good protien source. Throw them on a salad or into a stir fry for a kick of protien and fats. You can also get black soy beans in the can for mexican dishes, they are LC and high protien, as well as edemama which is green soybeans in podo r you can get them precooked for snacking.
