Oh and FWIW, if you want to start teaching etc, do not let weight worries get in the way of that. I had students who liked me BECAUSE I was bigger. And one of the most popular teachers in NZ when I started was a woman called Fatina (wah wah waaaah) who was one hefty mother. Having some extra weight can be reassuring to students and if you end up teaching a regular class your core technique will strengthen up immensely. THat's regardless of how quick or slow the weight comes off!
