Seconding what has already been said. You want to follow the basic tenets of Induction - getting about 20 carbs of GOOD carbs - veggies and such - on most days. If you really want to stick to only 20g, then if you have berries or some other carb only do so every few days so that on most days you are getting your 20 carbs from veggies. I'd recommend letting yourself vary between 20g and 30g a day and see how that goes.

One thing to keep in mind - no matter what you do there is a GOOD chance that you will not lose any weight or might even gain weight over the next couple of weeks. This is normal for lots of people, especially if they lose a lot on Induction (and you did - about 1/3 of what you want to lose!). So it might be difficult to tell if increasing your carbs (or holding them steady, for that matter) had any effect.

Above all, be patient and persistent and you will get there before you know it.

Keep the Faith!
