May I ask why you would consider eating calories earlier rather than later in the day? If you believe that eating calories earlier in the day would be better to try and "burn them off" before you go to bed in a somewhat fasted state then I will tell you that this is not what we are trying to accomplish during the carb up. It is not a time to drop fat, that's what happens during the week. The weekend should be thought of as your time to recomp. You will regain that muscle fullness that you have lost after a week of hard dieting. On the contrary to what you have proposed, IMHO the perfect CKD would have someone waking up at 2 hour intervals during the night and eating to keep steady levels of insulin throughout the carb up.good deal. i like the idea of sitting around eating. what about eating majority of calories earlier in day than later? also, is there anything besides fructose that should be avoided during carb up?
And while on the topic I really don't believe that there is any merit in timing your calories or carbs in such a way on carbohydrate based diets. It is more about calories in = calories out, IMHO. I have seen no evidence to suggest anything about supposed "carb timing" that everyone so readily accepts as gospel. And in practice I have gotten my leanest while eating carbs and calories proportionally throughout the day (before/after cardio, RIGHT BEFORE BED). I challenge someone to provide some studies to the contrary and if it is sound research then I may change my mind on the topic. But for now, I have eaten carbs before and after cardio and have woken up to eat a meal with about 75-100g of carbs at 2am for the past couple months and I am getting leaner by the week (please note that I am at the moment on a carbohydrate based diet).
This isn't to say that there is no merit to a CKD diet which is certainly based on the timing of carbohydrates (quite the opposite, there are 1000 of studies to back up its effectiveness). The type of carb and caloric timing I am referring to in the previous paragraph has to do with diets that utilize carbohydrates as the primary fuel source.
