i've generally been around 83KG with a large frame. My 'ok with me' weight is 85kg. That's about my normal healthy looking weight. So no, not light.
Everyone loses weight at different rates, but if you scroll back through my posts, particularly
this one you can see what i've eliminated to do what i'm doing. It's not easy for sure. I usually go all or nothing with most things, and this is another case. Doing this may not work for you though. Go to the doc and get your thyroid function tested, and your metabolism in general. If you have a slow metabolism, you'll lose weight slower, and sometimes not at all.
