Hiya, there is a specific diet which encourages you to eat 80% fat 15% carbs and the rest protein. Basically it is thought that the more fat you eat the less protein you should eat. Protien is meant to turn to glucose in some people if eaten in large quantities.
BUT I went on this plan for a month, and although I lost 6lb in that time, I felt bloated and sick all of the time.

I think the perfect ballance is to eat atkins levels of carbs (20 if you're on induction and 30 - 40 if on OWL) and then make sure you are not afraid of fats. Use them libberally - but don't over do them. I find this works best for me.

Good luck in your weight loss quest - and great news on the 4lbs! Whatever is working for you at the time is great!
