Get carnivore!

It's protein, but get this, it's made from beef instead of whey. A lot of guys from my box love it! It's by musclemeds

Since you asked in "eat/drink" form...How about on the eat sine--keeping a few cans of sardines or mackarel (the "in water" kind, not "in veggetable oil") to go along with your post-workoutre-hydration drink?

Liquidize some liver? Honestly I'd probably stick to water and then eat as convenient.

Jerky and coconut milk. San pellegrino(look at the profile) eggs.

The key before a workout will be CHOs and PRO prior to a workout--stay away from fat in and around your workout. I would consume a solid meal no longer then 2 hrs before your workout (3 hrs might also be good if you have a slower metabolism). 3 oz of lean meat will provide the protein (and BCAAs) along with a fruits like a banana and a kiwi--the banana provides potassium while the kiwi provides Vit C that helps with muscle stress during exercise. I know not the best combo but it is Paleo. You need to keep the meat as lean as possible as fat takes longer to digest--not to mention most of the fat in meat are long-chain fatty acids which are not necessary metabolism during exercise.

If you need a drink I would go with a fruit juice, like grapefruit juice with BCAA powder mixed in. BCAAs will help prevent muscle breakdown during your workout and the grapefruit juice will provide the CHOs and it's alkaline promoting so it won't decrease the pH of your muscles like cranberry juice would. I am not sure how you are with almond milk/coconut milk and egg protein but you could also try that as a pre-workout drink.

Post-workout meal should also consist of CHOs and PRO. If you have a large pre-workout meal then your post-workout meal is not as important and the same goes for your pre-workout meal (if its small, or non existent then focus on post-workout). Post-workout meal you can consume 6-8 oz chicken with 1-2 cup of non-starch veggies, like broccoli, cauliflower, carrots, etc. Veggies as you know are NOT super dense in CHOs so if you need dense CHOs post-workout consume fruit, or fruit juices. Dried fruits are also an opition as they are pretty dense in CHOs--but they can have a lot of fiber so be careful their too as fiber does take longer to digest. You can also consume the pre-workout drink I mentioned above as a post-workout drink immediately following--just make sure you get a solid meal in their within an 2 hr after working out.

If you want to lose weight, then keep your CHOs low post workout. High CHOs post-workout release insulin which blunts lipolysis (fat metabolism). Some would argue against this saying you need to replace glycogen stores, but as long as you are consuming CHOs prior to your workout and at other times during the day you should be okay. Once people get below a certain body fat percentage they can then increase their CHOs as they are more insulin sensitive and have utilized their stored fat as energy. Hope this helps! CHOs: carbohydrates PRO: protein

I like a combination of Xtend and Jack3d. Have to go easy on the Jack3d though or else I start foaming at the mouth.
