Well, it is something to analyze the data points I have already and to project where I might end up and when. Of course this **is** imperfect science, but it still is something to focus on and hold on to mentally as I face the continuing challenge of working to reach goal weight.
I basically searched my computer and best I can tell, I must have started this weight loss around the beginning of November 2006. I wasn't even sure, except that I knew I must have started after the middle of October. I found some info I downloaded about the Atkins diet on October 28th, and I think I started not too long after that.
Based on this I wonder if I didn't start out at over 400lbs, perhaps 410 or so. I will never know for certain, but based on my current rate of loss and the timeframe - it is possible. Anyhow, at whatever weight I started (and that is all hypothesis, since I didn't have a scale that would weigh me then anyhow, and I was already into my weight loss before I weighed across two mechanical scales at ~370 lbs), I have enough real data from multiple weighings to know what rate I am losing at currently. I had my nice digital scale from 370 lbs on.
If I continue to sustain weight loss at this rate I can postulate an optimistic date that I will hit goal weight (which currently is about 170lbs). This is probably unlikely and a little overly optimistic. Still there are others who have lost similar large amounts of weight in a relatively short timeframe.
Chances are though, it will take me somewhat longer to get there, as the rate of loss is likely to slow as I near goal weight (I would assume). Also, most people encounter a weight loss stall (or several) as they try to lose down to their goal weight. So I generated an estimate based on a more conservate loss of weight overall, that might take this into account. I now have a good series of high and low benchmarks (brackets) to compare myself against and to overlay my actual weights against - and see how my progress is going.
I may also find that I am overly optimistic about my goal weight at some point, and have to move that up to a higher weight at some point - but I am going to try to shoot for it (170 lbs) and see how healthy I look and feel (and am) as I get nearer to it. It is an ambitious goal. I weighed more than that when I graduated High School.
