People on a weight loss regime often resort to eating a diet low in carbohydrates. The Institute of Medicine says that around 45 to 65% of a person's daily calories come from carbs. A low carb diet is designed in a way that it creates a deficiency of carbs in the body in order to encourage it to switch to a different fuel source. This eventually leads to significant weight loss and also stabilises blood sugar. Side effects of reducing carb intake can be experienced during the initial phase of low carb diet.
