re: Keto Vs. Vegan

If you're really serious about it I would focus on quality of food first. Start slowly cutting out processed foods from your diet. Things like highly processed meats, GMO foods, non-organic foods, fast food, etc. these will all negatively effect your body and your ability to absorb nutrients. Quality food is critical when trying to add muscle and/or lose weight.

You don't put shite gas in a NASCAR and expect it to run at peak performance. Your body is the same way.

Once you've mastered eating "clean" foods you can really start tweaking macros and see how certain foods help you.
