According to Anthony Colpo, one of the most articulate of the Atkins diet defenders:
"Some folks have been so inculcated with the simplistic "fat makes you fat" theory that they just cannot believe a diet high in fat can lead to a loss of bodyfat.
The fact is, high fat diets can result in spectacular fat loss - as long as carbohydrate intake is kept low. Eat a diet that is high in both fat and carbohydrate and your bodyfat percentages will head north real quick! "
