Carb Nite is created for one purpose only, fat loss!  In other words if ones goal is to lose fat and spare lean tissue, Carb Nite is the answer. However, you are trying to cut weight, and train MMA at the same time, so you are basically breaking all the rules with carb nite, which are to avoid high intensity cardio during the majority of the ULC days. I don't claim to be an expert, but I would venture to bet that if Kiefer were you coach, he would have you do CBL, but just tweak more to keep you losing fat, and maintain your strength.It sounds like you just gave up on CBL too fast, and are trying to learn on the fly, in a hurry, and that is usually a recipe for disaster. The objective you are trying to achieve requires a substantial amount of tweaking, and some trial and error, and if your trying to cram on this into a short period of time without allowing for any learning curve, there is a high chance of failure to reach your desired outcome.With that being said, you should be focused on Strength Accumulation, keeping your carb loads very controlled, and timed very specifically. I would say time your loads pre-workout days, train fasted, this way to burn through as much of the glycogen as possible, priming you for the next load. I would recommend go back through the book again, re-read the tables, re-read the chapters, keep detailed notes, note your goals, and see which points help you refine your game plan.In lieu of hiring a coached familar wit CBL, you need to become your own student, and really study the material and be willing to fail in order to learn. That is what is nice about hiring an expert is they help eliminate the learnign curve, unfortunately not everyone can afford a coach, or a coach is not available, which then leaves us to do our best to figure it out on our own. Remember in the book, it states "some assembly required" and Kiefer says repeatedly that the tables are rough estimates, and will require tweaking. Edit: Also you say you do weightlifting, I would make sure you do a more power lifting style program, which focuses on strength, If do you more hypertrophic type bodybuilding training, i.e. higher reps, 8-12 range, your muscles are going to grow and you will put on more mass, if you focus more on the lower rep ranges 3-5 you will be more strength focused and less likely to pack on mass, this is why bodybuilders for the most part are not as strong yet have bigger muscles, and why you can see a lot of PL'rs who are strong as hell but are not always necessarily heavily muscled, of course their is always exceptions, but you get my point.

Gotcha ! Im going to hit that CBL hard again tonight, and really try to tweak my macro's the right way. Yeah my training basically breaks down to 2-3 days mma, 3 days weights ( emphasis and strength/power), 2-3 days cardio.  Some days weights and hitt are cramed, and MMA training usually lasts 120-180 minutes so the need for CHO is there, but Im going to limit them on weight training days, and go keto on non weight days. Thanks alot
