I was refering to a diet full of delicious red meat, bacon and carbohydrates. The diet is popular in many countries and I love it too.
But it is a simple fact that such a diet is impossible in Japan. The price of meat, especially red meat is extremely high.
PS: I agree with you that a carbon restricted diet has obvious healt benefits. My point was that following an unhealthy red meat diet in Japan is impossible due to price.
Severe carbohydrate restriction may be to difficult for most people to stick with, and therefore not optimal for keeping the weight off. But there is is irrefutable evidence that carbohydrate restriction will result in weight loss.
