I would suggest not pigging out on the carb up. You should eat a good amount but try to not eat junk food like pizza, and ice cream. If you can't deal with not eating this shit then theres no point in dropping all this weight. Your just gonna gain it all back in time and feel even worse. When you get to 10% bf, then you can have these junkfood cheat meals. Remember CKD is mainly for people with low bodyfats who are trying to go even lower for competitions, and they can handle a little junk. Other then the Post workout shake after yoru depletion work out on friday where you should have dextrose (a high glycemic carb) and the meal after meal with some other moderatley high glycemic carbs, I would limit yourself to good low glycemic carbs like oatmeal, yams, brown rice, etc. Limit your fats during your carb up!
As for supps Ephedrine and Caffeine works good. You could also try some green tea extract, but stick to your diet and getting the cardio in is the key to fatloss.
