I was very strict, I was near 270lbs (probably a lil more) and got down to 230 in less than 1 month, if thats not a woosh i dont know what is!

The key is to be very strict and to have someone do it with you if possible! Here are some things i learned:

1. Drink as LITTLE caffiene as you can, and as MUCH water as you can!

2. Stay away from protein bars during ketosis... use them for after when you just want a low carb snack. The "net carbs" can refuel your liver with sugar and knock you out of ketosis!

3. Weight comes off in bunches, nothing for 3 days or so then BAM! 5 lbs right off (of course i weighed 270 so more comes off when your that fat, but you get the idea)

4. Dont be skimpy with the fat, your body needs sugar OR fat, you cant do without either or you will make your body sick! Try and keep fat to 60% or more of your diet.

5. NOTHING TASTES AS GOOD AS BEING THIN FEELS!!

Hope this helps you all, this is just some of the stuff ive picked up since I started researching this. YOU CAN DO IT!
