Low carbohydrate diets are not without risk.  

Low carbohydrate diets are at near epidemic levels and you cannot walk in a gym and throw a rock without hitting a half-dozen people that are currently following one form of the diet or another.   Restricting carbohydrates has become a popular way to lose weight quickly in recent years.  There are many different low-carbohydrate diets to include the Adkins, ketogenic, paleo, Protein Power and South Beach diets.  The low-carbohydrate books would like you to think that carbohydrates are the enemy, but reducing your carbohydrate intake might not be the panacea for good health that they want you to believe it is.
