In order to "function" properly and stay healthy you should be getting anywhere from 125-175 g of Carbs a day. The average American is getting anywhere from 200-300 g a day, which is why the whole low carb thing came out. I know a lot of you are Canadian so you're probably just fine. Carbohydrates are one of the body's macronutrients, which the body needs to survive, along with water, lipids, protein. If the body doesn't get enough carbs it has to look other places to find them. And it goes to the muscles. The muscles are infused with water and carbs. So what happens if you're on a low carb or no carb diet and aren't getting 125-175 g a day is the body will lose muscle. So a lot of the weight you may think you are losing is water weight from the muscles and also muscle itself. This info all comes from a Anatomy and Physiology class I took a few months back. So I'm not full of crap. Just be careful if you're on Atkins. The odds of gaining that weight back may be extreme. The body will go into overload mode and start turning muscle into fat for conservation purposes. Think again people!!!! Just exercise and cut back on calories, watch carb intake. Stay in the range and you'll do fine. If you want a good place to monitor all food intake go to fitday.com .....it'll monitor all your intake for free. Good luck!
