Everyone who’s ever been on a diet knows all to well the anxiety that this simple piece of machinery can induce. Nowadays, when there are scales that tell you your weight within a .1 lb margin of accuracy, people are even more likely to obsess over every tiny change in the readout. Well, I’ve got news for you. For some it might come as a relief, for others a negation of weeks of hard work; changes in your weight don’t necessarily mean anything about changes in your body composition!
Changes in body weight can come from numerous things. First and foremost, our bodies are made mostly of water. When we drastically change our eating/training habits, it can take our bodies time to adjust. One place I see this most often is when people go from a Standard American Diet onto a low-carb diet; they tend to lose astounding amounts of weight in the first few weeks, sometimes as much as 10+ lbs! While a bit of this weight loss is surely fat, a lot of it comes from the fact that a carbohydrate and calorie restricted diet will deplete people of the glycogen stored throughout their bodies.
Glycogen is the form of carbohydrate that is stored throughout the body in muscle cells, fat cells, and the liver as fuel reserves. For each gram of glycogen within a cell, it brings with it 3-4 grams of water. So, let’s say you’re carrying with you 1000g of glycogen – during that first week of dieting, if the majority of that glycogen is depleted, you will also lose 3-4kg of water – upwards of 10-15 lbs!
Also, to a lesser extent, you can even lose a pound or two by taking a good shit. Sorry for the vulgarity, but hey, when you’re talking about the human body, shit is bound to come up sooner or later, I might as well break hearts now.
So, if our weight can fluctuate as much as 10 pounds in a week without indicating any truly significant fat loss, how should we approach weighing ourselves? Well, you have two options, depending on your level of meticulousness. And despite which path you choose, there are some rules you should always abide by.
Rules for Weighing Yourself
1) Always weigh yourself at the same time of day:
I recommend first thing in the morning. At this time, you will have a fairly consistent amount of fluid in your system, and it will have been quite a while since your last meal, minimizing the effect that has on your weight.
2) Write your weight down:
Even if it’s not a number you like to see, you won’t be able to keep long term track of your progress if you ignore it and try to forget about it. Write the number down somewhere! Oh, and don’t fucking lie to the notebook and round down, you’re only hurting yourself when you do that.
Weighing Method Number 1: Every Day
This method is for people who like to keep very careful track of their progress. I personally weigh myself each and every morning, first thing out of bed, and jot it down in a spreadsheet. Now, let me say, this method is not for people who obsess about the tiniest uptick in their weight. Only do this method if you are able to see sometimes drastic swings in your scale readouts without freaking out, jumping off the wagon and binging on a dozen donuts. Weight loss is never linear! I recently went off a very low carb diet (for many reasons) and immediately saw the scale jump 5 lbs. Was I shocked? No, because I understood what was going on, and had the data to back it up. Why then, if things are so inconsistent, would you want to weigh yourself every day?
Trends. With a few weeks of daily weigh ins, you will be able to see past the day to day fluctuation in weight and be able to see the trends. A fairly consistent downward movement from week to week, despite the few large swings up and down, indicates progress, and that’s all we need to see. I highly recommend this method for anyone who has already dialed in their fitness for the most part, but who would like to approach lower body fat percentages, or possibly put on some more lean mass.
This also works well for people experimenting with carbohydrate refeeds. Day to day fluctuations in weight are a good way to measure whether or not you are ingesting enough carbs on your refeed days to properly replenish glycogen stores. If you don’t know what a refeed is, then that probably means you don’t need to be doing them yet.
Weighing Method Number 2: Every Other Week
This method is for the ruminators out there. If you find yourself weighing in multiple times a day, just to see, or you lose your shit over a weight gain of .2 lbs, this is the way you should be weighing yourself. Every other week, pick out three consecutive days on which you know your diet will be dialed in, and weigh yourself first thing in the morning those days. So, if you normally have a cheat meal on Friday, weigh yourself on Tuesday, Wednesday, and Thursday, since the cheat meal would certainly effect your weigh ins later in the week. Then, average these three weights, write that number down, put your scale away, and don’t even think about weighing yourself for the next two weeks! Trust your plan is working, and just let it work! The last thing you want to do is raise your cortisol levels by obsessing so hard about your diet… that would prove counter productive.
By weighing yourself over 3 days and taking the average, you will minimize the effect of the slight fluctuations in water weight, and will be able to better see the actual trend of your fat loss. If over the course of two good weeks of dieting and exercising you don’t see any change in the 3 day average, you need to make a change of some sort. If you do see a loss, then keep it up until it stops working for ya!
Weighing Method Number 3: Don’t fucking weigh yourself!
For lots of people, measurements and photographs are all the proof they need. I know that, personally, a photo means much more to me than a number, and having a piece of clothing fit better than ever (or perhaps fall off) is enough of an indication that I’m on the right track.
At the end of the day, no matter what the scale says, stick with it. Eat good, whole foods. Exercise smart. You might have to tweak some things along the way to reach your final goals, but by doing anything about your health and fitness, you’re in a better place than you were when you were sitting on your ass eating Fritos and a pint of Ben & Jerry’s every night. Don’t get discouraged and slip back into your old ways… we all know where those were getting you.
…Mmmm… Fritos.
