None in particular just basically get none fiberous carbs under 30 grams for 6 days straight, then refeed on the 7th day and repeat. Refeeding is optional If for example your cutting for a show, no longer than 4-6weeks. It's really hard to go that long without a descent amount of carbs. I went 6 weeks with carbs under 30-50 grams for one of my physique competitions and came in extremely flat and not feeling well. Won't do that again as far as cutting, lessons learned. But I shed body fat like you wouldn't believe. I have done this after injury and time off to help get my BF to a manageable level. I went from 25-27% bf to 11-13% in about 8weeks after being injured, depressed and not working out for 6 months. I actually felt pretty good but again, I looked really flat.
Now I personally refeed every 2nd Sunday. I do that because you kick your body out of ketosis for a few days each time. If your doing a lot of HIIT for cardio, like I do. You need to refeed yourself with carbs to help your body keep up with the trauma of exercise and sustain fat mobilization going. You do need small amounts of carbohydrates to process fatty acids in beta-Oxydation.
