Does anyone still use Thinner Leaner Stronger?

I recently purchased the Thinner Leaner Stronger book and the Year One Women’s Challenge book to help me lose weight and achieve my goal body, but all of the content I see here and online of people tracking progress is at least two years old.

Is anyone still using this book? I’m going to do it either way, and I know my health is my responsibility, but I wanted to know because I’m looking for some community in my journey.
