I know that, in theory, you should weigh one day at a specific time (like when you first wake up), eat all week on your plan and weigh a week later. If you're at maintenance, you'll weigh the same.

I suppose it's tough to say though, because if you don't have much weight to lose, then even the two-week induction will eventually lose effectiveness and it may seem like you can't lose at all regardless of what you try. There's also the rule of five. If you gain more than five pounds at any time--especially if you're on maintenance--it's back to induction for about four days to restart.
