This so called meat/eg fast is just Stillman's diet. It's a well known plan which has been round as long if not longer than Atkins. It's very low carb and also low fat. I do it from time to time for about 5 days to break stalls. The protein is a powerful appetite suppressant and my calorie intake on Stillman's is always less than Atkins despite the fact that I eat as much as I like.
