You can stay on induction for long as you like. I was on it for a year the first time, with good results (lost 45 pounds in approx. 7 months, with heavy exercising).

I didn't really add anything back post induction, other than macademia nuts, pork rinds, and a bit of cream cheese every few days. Had no dairy other than that.

Of course I don't need to have a large variety in my meals and don't bore easily. I could eat the same thing every single day.

Congrats on the weight loss and keep it up!
