I have started a special diet called The Ketogenic diet
I've heard of that. I don't think I could do it.
It took me awhile to get used to it; however, after awhile, I started enjoying the high-fat, protein diet
Yes it burns a lot of fat doesn't it?
Yes, thats the key to the diet. It forces the body to burn fats instead of carbohydrates
Does it make you sluggish though?
The only side effect that I have dealt with is constipation which is mostly due to fluid restriction
How much weight have you lost?
I have lost a few pounds; however, the real reason why I started it was because it helps with epilepsy, and my doctor recommended me to try it. It has surprisingly has helped. 
I've heard it helps with epilepsy. My five year old has absent seizures.
