This is what works for me when I start dieting in the spring. I sort of diet in the off season, but cheat more frequently around the holidays and such. I tend to start serious dieting around spring break (March). The idea behind cycling carbs is the body will burn off fat when glycogen is depleted. However there is a trick to it, you can't go low carb everyday or else you will lose significant muscle mass and just generally feel like sh*t. So in order to avoid or at least minimize that factor, you need to cycle carbs. For simplicity, say you start on a Monday. Now this is what I do, depending on your body weight, you may have to modify it. Now, I weigh 180ish, but will drop down to 165ish in the spring. Monday-Wed Moderate carb days 150-200g/day range. Thurs/Fri Low carb <30g. Saturday/Sunday High carb > 500g/day and perhaps a cheat on either of these days. Now you can get deeper into it to achieve greater fat loss more rapidly, for example go 4 low days, tues-fri then bring glycogen stores back up over the weekend with two high carb days, do a moderate on monday, and go low again for the remainder of the work week. The more low days you have, the more drastic the effects will be. However 2 low days is sufficient for me to keep fat off. The key to carb cycling is the high days, that bring everything back up. You do feel like sh*t on the low days however, that is unavoidable. This method works though, if you stick with it. Great for contest prep.
