+1 for undernourishment.

Discovered that as a broken uni student, and has become my goto fix to lose weight. Lost 10-11kgs over the last year by means of that. The occasional “cheat” (mostly social events really) slows the process down but don’t really stop it. It’s not really a fast process though… but it strongly depends on how under nourished you are and how active you are. For me keeping myself between 8000 and 10’000 steps a day was sufficient.

That’s great progress. It comes down to inverting the normal indulgence cycle. Once you discover that under-eating can feel better than over eating – you feel immensely better.
