From personal experience with an Atkins type of diet I have to say this is one of the worst diets out there. Not only is it VERY unhealthy, high animal protein (which is full of saturated fat)with little or no essential carbohydrates. You loose muscle and have little energy with a low carb diet which can have serious negative health effects. After loosing weight --the diet was so restrictive that when I reached my goal weight I quickly gained all the weight back and then some, which all landed in the unhealthiest areas -- my midsection
I suggest anyone looking to loose weight should exercise, eat in moderation and try a vegetarian diet which is the healthiest. By doing this I have lost weight and have kept it off with no feelings of depravity at all.
