look at bodybuilding.com in the article section, read up on the ketogenic diet and CKD. Yes you obviously are going to have to cut out your pre-workout carbs. the 1-2 g of carbs in my ON whey protein powder never kept me out of ketosis at all... so that wont matter. To get into it fastest, do early morning fasted cardio the first day, and then just eat fatty foods like bacon, cheese, eggs with butter, cheeseburger, mayonnaise, etc. The first two days I didn't worry about being in a caloric surplus or not - i ate til i was full. And within 3 days I was pissing ketones. Do LIGHT cardio every day. Go to a pharmacy and get ketostix. they will let u know if ur pissing ketones or not.
There I did ur research for you
