I think the thing with the issue of scales is, it's a very personal one. And you have to do what's best for you. Some weigh daily to note fluctuations and count their weight on a particular day (I do, for example. I weigh daily and count my weight officially on Sundays.) Some never ever weigh themselves and only go by the fit of their clothes. Some never go by weight, only by the size of their clothes. Some weigh themselves daily and freak out because of the natural fluctuations and get frustrated. Some weigh once weekly, maybe even twice. Some only weigh at the doctor's. And so on and so on.
Personally, I believe there is nothing wrong with any of these methods (well, except for the freaking out part. We must realize the natural fluctuations that occur all throughout the day, on a daily basis.). You have to choose what suits you the best. If scales freak you out, and going by the fit of your clothes & being weighed at the doctor's suits you best, then it sounds like a good plan. If you are contemplating home use of a scale, but they freak you out, maybe you'd be better off weighing once a week, or even biweekly, and that way you could keep up with your loss at home.
Also about the weight not coming off as fast as you'd like. There are many different factors. What are your meal plans? Also, people have varying metabolisms, some aren't eating enough calories, some may be eating too many calories in the form of something or the other, possibly not enough vegetables and exercise, age, even your weight definitely plays a role in how much you lose. But it will come off in time. The SBD wasn't meant to be a rapid weight loss 'diet', it's meant to be a lifestyle plan so generally I'd think, 1-2 lbs a week or so. For some, weight loss is even slower. For others, even faster. (I assume you know that, so I don't mean to come off know-it-all.)
I'll give you an example using myself:
I'm 24 and I've been OP for like 2 months now. Initially I didn't lose much in Phase 1, only 3 lbs, then suddenly 8 lbs came off just like that for a total loss of 11. My weight loss goes in spurts and stalls. Now, I'm still stuck at 11 pounds net loss... the scale went up a bit for a few days there, and now I'm still at 11 lbs, and it seems I didn't even lose at least a lb the past couple of weeks.
So, everyone is different and the weight loss varies drastically. Example: Someone twice my age might have lost more than that in a shorter amount of time. Why? Who knows.
They may do more exercise than I do. They may have a better metabolism. Or etc etc etc. Someone my age may have lost more due to more exercise for example. Or someone my age or older may not have due to other factors... there's no comparison really. Someone my height and weight who exercises less than me may have lost more than me. And so on and so on and so on, those are just a few examples. Our bodies are all so different! With time, you'll see the weight come off. You may have just hit on of those annoying stalls!
Good luck.
