I've been on a low carb diet for a couple of months now. Went a tad stricter 3 weeks ago and am currently 11kg down.
My bodyfat drastically reduced, my belly disappeared and I am feeling a lot healthier. Problem are the more expensive meat-heavy meals that go so far that I just don't enjoy or want to eat anymore - and of course very easy degeneration of muscle mass if you're not careful.
Nevertheless, I'm loving it. I wish I tried this earlier instead of a half-assed diet. I won't be doing it forever but to fast chop down on some body fat, it's amazing.
