When you go extremely low carb for more than 3 days or so , you are actually putting yourself into a ketogenic state (think - the first 2 weeks of the Atkins Diet). The Atkins Diet can make you drop weight - first water because complex carbs require water to hold them in your body (thus the bloat you feel when you eat a lot of them) so you see that big initial "weight drop" (its not fat ... its water weight). Then you can continue to drop - and Atkins people often drop fat & weight because they are watchign their total cal intake for the first time in their lives as well - so not necessarily that its a great diet - just its a controlled diet. But as you continue to stick to this crazy low carb state, you start to drag ass & feel lethargic. This is not a great way to build muscle simplly because you have no energy for lifting. And further because your body is now realizing that its carb intake has been stifled waaay below what it is used to, it will eventually respond by slowing up the metabolism - the rate at which it burns energy -- because it thinks there's a limited amount, and possibly not a replenishable source (e.g. like in a drought -- its a survival mechanism) of carbs so it holds onto everything it has ---> that's how you see people hit plateaus and get frustrated when they follow continuously low carb diets. Your body NEEDS carbs to run efficiently. Not EXCESS carbs but just enough.
I would suggest doign a carb cycle schedule - over a 3 day period do the following:
Day 1 - High carb (e.g. 150 g carb - e.g. 3 servings of complex carb over the day - 1/2 c oatmeal, 3 oz sweet potato, 3 oz potato)
Day 2 - Med carb (e.g. 100 g carb - e.g. 2 servings of complex carb over the day)
Day 3 - Low carb ( e.g. 30-50 g carb - e.g. 1 serving complex carb)
Day 4 - repeat Day 1.
Best to match up the higher carb days w/ your heavier lifting days - e.g. leg day. Low carb days on cardio only days. These dont' have to match up exactly to your training schedule - but if you can try to get them close or anticipate less energy if its a low carb day but its a heavy training day.
If you are carb sensitive - use Glucorell - 1 pill for each 30 g of complex carb in your meal. But if you feel like you can't lose fat when you eat carbs - that just wrong. I cut 30 lbs & 8% bf using carb cycling and its a staple of my competition prep. But if you go low carb forever and then slip cuz your tired, hungry, whatever - sure your body will respond because it is dragging on no carbs for too long.
And easier to shop. Shadow mentioned a while back that everything works, but only for so long - meaning that I need to stay on top of things and have enough brains to switch up when my program stalls.
