I have to be honest: I'm replying because I was looking through some of the newer journals, trying to find someone about my age (26). At first, I was just curious as to common ages of primal individuals, but I didn't find many that were young, so I decided that maybe I should try letting the younger people know that they're not alone.
Good luck with the weight loss. I have to hold myself back from giving advice on that because I'm usually the most knowledgeable person in the groups in which I take part, but I know that there are people here that would put me to shame.
I would like to say that it's sometimes difficult to notice a difference. When you're losing weight at 1-2 lbs/week, you end up getting used to the new size very quickly and think of that as your "normal" weight. It's not until you look back a few months later and realize just how much larger you used to be (or when your pants start falling down) that you realize that you've lost weight.
As for scales, I'm not a fan of the normal ones because absolute weight is not really something that deserves a lot of attention. I have a body composition scale, which measures my BFP, lean body mass, water weight, and bone mass. I think that's a pretty good way to go if you'd like to get a scale.
