The Daily Weigh

One popular dieting tip is that you shouldn't weigh yourself every day. Because you're not going to drop pounds overnight and weighing yourself every day will just depress you. Instead you should weigh once a week.

This doesn't work for me for a lot of reasons, but I'll let Google 15 explain one of them. Google 15 is a Google app on my home page that I plug my weight into every day.

The Google 15 encourages you to get on the scale every day by calculating a moving average from your daily weight. We then plot this average alongside your daily scale weight and a goal weight that you set--this gives you a better idea of your weight trend by masking most of the day to day noise that variances in water weight introduce.

If you've ever tried to lose weight, you've undoubtedly experienced the excitement of getting on the scale to see that you "lost" two pounds since yesterday. Unfortunately, that tends to be followed by the depression that you "gained" three pounds the next day. It's impossible to "lose weight" every day according to your scale weight, so as a result, most people cultivate an irrational (but very real) fear of their scale and only climb on to get feedback on their weight loss efforts every week or two.

Your exact scale weight isn't really important as long as it's "ahead" of the trend you're aiming for. If you're trying to lose weight, you want your day-to-day scale weight to be below your moving average--concentrate on your moving average weight, not your scale weight! In the example on the right, note that on 4/10 it looks like the user "gained" three pounds according to the scale weight, but the moving average merely leveled out. But this is no reason to panic--the next day's weight continued the downward trend.

Of course, the big secret that you never hear is that the hardest part about losing weight is keeping the weight off once you've lost it. The Google 15 generally considers you to be on goal as long as your moving average weight stays within 2.5 pounds of your goal weight. So don't stop using it once you've made your goal weight--enter your weight every day and it will give you an early warning if you start to pack on the pounds!

As you can see, I weighed in at 172 today. I don't think that means I've lost three pounds. I don't consider it a pound lost until I've weighed in under my previous weight for at least a week. But if I only weighed myself once a week, that 172 might give me a little more false hope than if I was weighing every day. The good news is, if this trend continues, it does look like I can officially say I'm losing weight. Yay!
