going low carb and olympic weightlifting

I've been trying to drop weight the old fashion way, calorie counting. I've been failing miserably. I've never really been able to lose weight by counting calories. Back when I used to compete in triathlons I was able to lose weight going low carb, and then maintain my weight by counting calories. I asked my Olympic weightlifting coach Shane Miller if he thought I could still be successful in olympic weightlifting while going  low carb, he said ok but that he'd want me to eat carbs before and after my intense weightlifting days on Monday, Wednesday, and Fridays. I have a weightlifting competition this Saturday at Miller weightlifting and I don't want to mess up my performance so I won't start the new diet until Sunday. I tried to google low carb and olympic weightlifting and there wasn't any information online. What info there was had to do with bodybuilding which isn't applicable to olympic weightlifting. I also tried looking up some info on low carb on some olympic weightlifting web sties, again there was no info at all. So when I do start the diet I'll post how I feel and how my strength is doing with the low carb diet. It'll be an interesting experiment.
