I also ran carb back loading for probably 2-3 months. I had good results at the beginning and then needed a break from it. I went from about 217 down to 205-207. Once I hit this weight I started to lose a lot of weight from my main lifts.
I found that I had good energy throughout the day, but about half way through my lifts I would start to crash. It was also tough for me to get in enough calories. I would do this again, but I need to do it smarter.
Here was my basic day:
7:30am-50 gram shake
10 am -50 gram shake
12 pm- salad w/ chicken, and olive oil
2:30pm- 30 gram shake
5 pm-handful of almonds
Post workout meal-everything I could find
I think for me, my body seems to burn fat better with less shakes, and keeps my metabolism higher.
I think this is a great approach, I just needed to plan better to make sure I kept my calories higher. I had the same issues with low carb after about 3 months.
