After my first son was born (5 years ago), I joined weight watchers (6 weeks PP), it took me 18 months to lose 20 kg (plus the 20 kg I gained in pregnancy, that came off in about a month), to my lowest adult weight.
For some reason things fell apart after this, and I ate a lot of shit, rapidily, and gained that weight back in around 4 months.
Then I got pregnant again. Ate better this time (SAD) but gained nearly as much weight. Once again lost the gained pregnancy weight in around a month, and joined WW again. Didn't quite get down to my previous low, so tried the whole lean protein, brown rice and tons of spinach 6 x a day weight loss, as well as going a million gym classes a week. Strangely enough my weight didn't move too much. Moved on to half marathon training, again weight didn't move too much. Tried various low fat, higher carb eating methods. Then began lifting heavy, but around this time discovered primal and CrossFit. Then my body comp changed heaps! Yes the scales weren't going down. But I actually started to wake up from my fog, and lose all my aches and pains and digestive issues.
But then shit happened at CrossFit, and I got injured plus other shit, and I stopped going, and went back to more frequent binge eating (was still doing it sometimes while primal). And then I gained back nearly 20 kg.
I recently discovered HFLC, and now the scales are actually moving down, and I feel amazing.
