Limitations of calorie/weight loss calculators

It's weight-loss time: My fight is only 1.5 weeks away, and I've got about 6 or 7 pounds to lose to meet fight weight (142, I'm 148 or 149 as of this morning).

Now, this is not really difficult to do. There's gonna be a lot of water weight lost with a little bit of "actual" weight loss over the next couple of weeks.

But just go ahead and try to put that weight loss goal in the calculator on this site. 1-2 lbs per week is not enough for my weigh-in. Of course the last time I bothered to track weight loss was... last time I was cutting weight for a jiujitsu tournament. And I couldn't use it then either, because I had to lose 10 lbs in a couple weeks or something like that.

Before that, in my first jiujitsu tournament, it was 5 lbs in 3 days.

Most of the time, I'm not trying to lose weight at all. I just try to keep myself down at 150 or below, and I'm good. It's only for weigh-ins that I care about the scale at all, because otherwise I go by how I look and how my clothes fit. I can tell when I've gone over 150, easily.

Of course, the drastic weight loss is always just for weigh-ins, and I'm typically back to normal within a day or two.

Luckily, I don't expect my clients to lose weight the way I do, because they're going for sustained weight loss, not a quick weigh-in.
