One of the things you’ll discover as you continue with a long term weight loss program is that the scale, while it may be the defacto measurement people use, is not necessarily the best one. It’s a great guide and for a general look at how you’re doing it’s very useful and important. However, taken by itself, it can be misleading.There are actually quite a few measurements that should be tracked on a regular basis. BMI (Body Mass Index) is a very common one. Doctors are starting to use this more often as a general guideline to someone’s health. There are all sorts of charts on the internet indicating where you should be considering your gender, age, height, weight, etc. Here’s an example from http://www.consumer.gov/weightloss/bmi.htm
You can get a rough estimate of your BMI from lots of calculators. The site I mention above has one. BMI is not without it’s problems. The biggest issue is that it doesn’t do a good job taking muscle into consideration. It’s simply a table based on height and weight. Line up the x and the y axis and wherever those two meet in the middle is your BMI number.
Body Fat percentage is another measurement that’s important. For a normal person (i.e. some not in a clinical environment or with access to expensive equipment), this is measured either with body fat calipers or using a Bioelectrical Impedance Analysis (BIA) device. I’ve tried the calipers, they’re a pain to use. I’ve read other people’s experiences with the device that indicates with practice it gets better; easier to take measurements and more accurate. If you want to put the time in, go for it. On the other hand, a typical BIA device is a piece of cake. You just enter your height, weight and age and grip the device. The problem is, those devices aren’t cheap (I use the one at my gym so it’s “free” as long as I’m a member). To do the same thing, you can get one of those scales that takes the measurement when you step on it. I have the Tanita BF-679W. It seems to work okay but it disagrees with the one at the gym by quite a margin. I think the main thing to concern yourself with when considering these devices is consistency. Use it at the same time of day, under the same circumstances, as much as possible. For example, right after you get out of bed and go to the bathroom.
Yet another method of measuring yourself is with a cloth tape measure. This happens to be my personal favorite. Doing this by yourself can be quite a trick (just try measuring your own bicep one handed with a cloth measuring tape). Fortunately, I found a device at a local sporting goods store that fixes that problem (and comes with a body fat caliper in case you want to try that too). The device is called the Myotape Body Tape Measure from Accufitness. It’s a nifty little device that makes a loop out of the measuring tape and lets you lock a measurement in place so you can see what it is. Here’s a picture it:
This little guy works great. It sells online for as little as $5.99 (Accufitness sells it for $9.99). I don’t recall how much I paid for mine, it was around $15 but it came with the calipers too. I like the tape measure method because this is a good way to indicate to myself that I’m having a real, visible impact on my goal of “becoming a former fat guy”. Once I’ve reached that goal, I’ll probably have to come up with something else. For now, it’s the one I like. The other benefit of this method is that it’s not one you should do all that frequently. Because you should spread it out to a weekly or monthly measurement, it’s not something you can obsess over.
What’s the best method to use? I don’t think any of them are “the best”.
The thing to keep in mind is that your weight is going to go up and down. Sometimes you’re going to feel like you’ve made great progress but look at the scale and not much will have changed. If you’ve been tracking your belly diameter (or arm, thigh, hips, etc.) or BMI or Body Fat percentage (or all of them) in addition to what the scale says you’ll be able to see that you’re having an impact (or not).
If I were using the scale as my only yard stick, I’d be a pretty sad sack right now. Since last April, I’ve only lost about 15 pounds. That doesn’t seem like much progress in 9 months. Fortunately, that’s not the only measurement I’ve used to track my progress. Besides losing 15 pounds, I’ve lost about 8.5 inches off my belly (with several other measurements like chest, thighs, etc. also going in good directions). I’ve lost about 6% in body fat, I can run (keep in mind, I said “I can run” not “I can run longer/farther/faster”). I’m more flexible, can lift more weight (I’m up to 3 chinups now).
I’m just trying to point out that the scale is not the only way to look at things and if you allow yourself to focus on that one thing, you’re risking losing a lot of valuable data points that can help you feel good about what you’re doing and that will lead to even more success.
Oh yeah, and don’t forget to take those dreaded “before” pictures.
