No, definitely not a trainer or dietician, but I’ve spent a lot of time over the last few years reading and listening to various experts in the field and people with tons of experience.
One such is Lyle McDonald via his site www.bodyrecomposition.com. He also has a FB group with the same name.
Another related to the carb ups specifically is a FB group called Cyclical Ketogenic Diet - CKD Carb Ups run by a guy that’s got tons of experience with keto and carb cycling.
