My big brother is this way, he did the "Fat Fast" for like 3-4 days through him into ketosis now he is looseing and is so happy he lost 30 pounds in 2 months, which is really great for him!
Also do you have the Ketone strips? If not you should get them they will let you know if you are in ketosis or not, if you are not then I would definately try the "fat fast" it would be worth a shot!
Well take care and let me know how is goes!
