This WOE requires a lot of self modifications. You have to kind of tailor the diet to your own needs.

1) your body may be already at the lowest weight it wants to be.
2.) Make sure you read the ingredients. Some companies market low carb products, but upon reading the ingredients, you'll find that there are hidden sugars in the form of corn syrup or brown sugar. Also stay away from all process foods, even low carb hot dogs while you're getting started. Those are usually the culprits for hidden sugars.

3.) When I had a problem staying in ketosis, I found the drinking a lot of water, I mean like at least 3 liters a day, helped kick me back in ketosis. I am also they type that cannot eat any low carb products such as Atkins shakes and bars. They stall me. When I keep it all natural, the scale starts moving.

I hope some of this info has helped you. If you have any more questions, feel free to stop by my journal and drop a dime!
