When To Weigh Yourself

Weighing yourself isn’t that hard. You just step on the scale and read the number.

But some people make a big deal out of the weighing process because of the anxiety that centers around the number they’re faced with. So they weigh themselves multiple times per day, or they don’t weigh themselves at all.

There is a happy-medium though! It is… weigh yourself once per day.

It doesn’t matter if you’re dieting or not. It does matter if you’re keeping a training log (you are keeping a training log, right?)

An important piece of information for your training log is your weight. Since there is an entry space for “body weight” in most every training log, it makes sense to weigh yourself once per day to obtain that number.

To get the best results, though, you need to be more precise than “once per day.” You need to weigh yourself at the same time every day.

That way you’ll get much more consistent and reliable numbers. You could choose morning, afternoon, or evening (whatever is most convenient), but I do suggest weighing yourself in the morning after using the bathroom, but before eating breakfast.

You’re probably near the scale anyway, and weighing in the morning cuts out quite a few variables that you run into throughout the day, such as food intake, fluid intake, sweating, etc.

With the daily weighing, you can better chart your weight fluctuations over time, but you can also notice problems more quickly. For example, if you lost five pounds overnight, chances are you are dehydrated and need to drink lots of fluids!

“Don’t Weigh Yourself Every Day!”

I can hear them now. The so-called weight loss experts will scream “don’t weigh yourself every day”, but that advice is just for dieters who freak out when they look at a scale.

As in, “OMG I ate 900 calories yesterday but I’m one pound heavier today! Nooo!”

That’s not you. You want to see the daily fluctuations because it’s an important piece of data.

You can compare your weight to what you’re eating and to the exercise you’re doing, and figure out if you are balanced. As I mentioned, a sudden weight drop is a good indication that you’re dehydrated (be sure to do a sweat rate test to help avoid that) or perhaps you’ve been on a low carb diet and have very little water retention, so you’re kind of dehydrated… either way, not a good way to start a race.

Weighing once per day makes sense for everyone though (athletes and dieters alike).

That’s because when weighing just once per week, you could have huge ups and downs. Let’s say you weigh yourself for a week and get these numbers (which is typical for me):

159, 162, 160, 161, 157, 160, 160, 164

Those fluctuations are natural for an athlete, and everything seems alright when you see the pattern.

But if I weighed myself once per week, I’d only have 159 and then 164. It would seem like I gained five pounds!

Maybe I was dehydrated one day. Maybe I ate too many doughnuts the last day? Maybe I had gone up to 175 midweek but luckily got down to 164 for weigh-in day? Who knows!

The Moral of the Story

Once you get past the needless debates, it’s very simple…

Weigh yourself each morning and record it in your training log (or app). Just keep it simple, don’t get hung up on day-to-day fluctuations (it’s not the end of the world), and you’ll be fine.
