As you may or may not be aware, I am currently attempting a low calorie – low carb (1800/100) to high calorie – high carb (2700/250) Zig Zag diet. This pattern can be 2-3 days low, then 2-5 days high. I am in my forth week with this diet and although I have only lost a couple of pounds, visibly my body has changed quite a bit. I have alot more muscle definition (biceps, triceps, inner chest and delts) and reduced belly / lower back fat (my wife pointed this out). I feel that I have successfully lost some body fat while maintaining muscle mass, which is exactly what I intended. Result
The science: This diet is all about keeping your metabolism spinning, revved up and therefore contstantly burning fat during exercise and more importantly when at rest. It’s based around zig zagging starchy carbs, mixing it up regularly, tricking the body so it never knows whats coming next (avoiding starvation / homeostasis mode), but always maintaining enough energy to power through your routines and continue burning fat. The main reason you do 2-3 days low, then 2-5 days high is to maintain these energy levels. Say you were to do more than 3 low days, energy levels would drop and therefore your metabolism would slow down so the answer to this is to carb up with exercise and get it going again. Pretty simple huh?
However… a little disappointing is that I personally feel I could have achieved MORE of a result.
By day 3 on the low side I would feel so tired that my momentum and ethuisiasm for training had vanished. I would get in there and find it so difficult to keep going, my strength sufferred too and I would have to give up before my desired reps. Once back on the carbs, my energy levels returned and off I went again. So… 3 low days is obviously too much for me.
My tweak for this is that I am (this week) only going as far as 2 low days at any one time. If my tired day is on third day, then I plan to carb up on this day (today) and see how it goes.
