After reading more on the CKD diet, I can safely say I'm sold. I don't see any problem with it, besides maybe being groggy and sluggish for the first two weeks until you adjust. That, and the bad breath issue I read about (breathing ketones is supposed to be "ech" - heh) which is my biggest worry because I don't want my girl to be displeased.
Anyways, for cutting a CKD is heavenly. It's cheap too. I'm thinking of basing my daily meals around olive oil and tuna. Protein, fats, no carbs. Sounds good to me. I'll try and eat some healthy solid fats though. And vegetables. If I do all that, I should be okay.
As for bulking, I'm still trying to find out what to do. Can I use that CKD Spreadsheet Mr. X made and just input the weight I want to reach, and follow those macronutrient ratios? Or do I have to do something else?
