Thanks to GotBeer from an earlier thread:

1. add variety to your diet,
2. add extra nutrition, and
3. begin OWL.

Adding variety will help you stick to the diet long-term - no boredom from eating the same induction foods over and over again.

Adding extra nutrition is, of course, always a good idea.

The best reason to stay in induction is that you haven't reached ketosis for some reason. Likewise, the best reason to go back to induction is after a cheat knocks you OUT of ketosis.

Does extended induction (while in ketosis) speed-up weight loss? Some say yes, but I have my doubts. If you are in it for lifetime weight-loss, then I think your best odds are to start OWL.

People who hit their target weight in Induction are most likely to return to their old eating habits - and we know where THAT goes.
