7 Times the Scale is Lying to You

Knowing When to Ignore the Scale

The scale can be a valuable tool in any weight-loss journey. It can tell you where you started and help you track your progress. It's the tool people use most as a measure of success--or failure.

As useful as the scale can be, don't forget that it's just one tool you can use, not the only tool. It's entirely possible for those numbers not to budge, but you find yourself having to tighten your belt because you've lost inches. Used regularly, the scale can help you check in with yourself and help you catch upward swings in pounds before they become double-digit problems. But used too frequently, the scale can drive you crazy.

If you find yourself weighing in often (multiple times per day or every day of the week) you're not doing yourself any favors. There are certain times when weight fluctuates, and seeing every fluctuation can be disheartening and really mess with your head and your motivation.

Many people find it difficult to give up the scale entirely, which is fine--but there are a few times when the scale isn't doing you any favors. Take the results with a grain of salt in these situations.

7 Times to Ignore the Scale

1.  Right after you've eaten.
You ate a meal and now the scale is up five pounds? What gives? No, you didn't actually gain that body fat from eating a heavy meal. It's more likely that your blood volume has increased due to the quantity of food you've eaten, and the weight of all that food is still sitting in your stomach and digestive system. Likewise, high sodium content can cause you to retain fluid. Chances are you're not going to like what your scale is telling you for a few hours or days, but that doesn't mean the meal you ate caused real, permanent weight gain.

2. During your first few weeks of a new diet or exercise program.
When you first start exercising or eating healthier, it's tempting to start jumping on the scale constantly to see progress. If you do, you may see some pretty significant losses, which can be really motivating! But don't get discouraged when those numbers slow down a few weeks into the new plan.

According to the Mayo Clinic, a rapid weight-loss is normal in the first few weeks of almost any weight-loss program. When calories from food are reduced, the body gets needed energy by releasing its stores of glycogen, a type of carbohydrate found in the muscles and liver. Glycogen holds onto water, so when glycogen is burned for energy, it also releases water, resulting in substantial weight loss that's mostly water (not body fat).

Try to avoid jumping on the scale too much during those first few weeks of a new diet or fitness program. It can be discouraging when your weight doesn't change as quickly as you'd like, and it can be equally discouraging when it stops budging after initial success. A moderate friendship with the scale--not an obsession--will help you gauge your progress but won't drive you crazy.

3.  Immediately after a workout. You just ran for an hour on the treadmill so you strip down and hop on the scale in the locker room to see how much fat you burned off. Sorry, but fat loss doesn't happen immediately. Any weight change you really see is lost water weight through sweating that will come right back as soon as you rehydrate. This is another reason why it's best to weigh-in consistently at the same time of day (just not every day!) for the most reliable measure.

4. You just chugged a bunch of water.
Just as you notice the loss from sweat, you can also notice the gain of water from drinking a lot of fluids. A large 16-ounce glass of water will translate into roughly a pound on the scale; your body will get rid of it, but immediately after you drink it, it's going to show.  

5.  Just before bedtime.  
You weighed in first thing when you got out of bed this morning, but before you hit the hay you find yourself wanting to check in again just in case you lost anything today. But try to hold back: If you find yourself a few pounds over or under your morning weight, you haven't suddenly lost or gained. Instead, it's just the timing of your last meal, your last workout, your last drink of water, and how much your PJs weigh. For this reason, experts recommend weighing the same day each week, at the same time of day, wearing the same clothing, using the same scale to get as accurate of a picture of your true weight as possible.

6.  You just had a baby.
You just gave birth to a beautiful 8-pound baby! So you hop on the scale thinking you'll see a dramatic loss. And you're disappointed that the scale has barely budged. While you might lose up to 15 or so pounds in a week when you account for the baby, placenta, extra blood volume and amniotic fluid, don't be discouraged if you don't see immediate changes. While that water and true baby weight may budge quickly, remember that you gained the rest of it over the entire pregnancy. Focus on eating right, getting plenty of rest and enjoying your new baby, rather than losing the pounds.

7. Practically any time during your menstrual cycle.
For women, it's a crapshoot. The changes that happen in your body throughout your menstrual cycle make your weight fluctuate constantly by up to two pounds during menstruation, your follicular phase, ovulation and PMS. Even more reason not to stress about a couple of pounds here or there, as this type of weight gain tends to come and go.

So don't let those daily fluctuations discourage you--or get you too excited--when it comes to weight loss. Use your scale as a guide, not the definitive standard of success. The best way to use the scale is to weigh in at the same time of day every couple of weeks. Even then, your body could be maintaining or losing body fat even if the scale never budges. Be sure to find other ways to measure your progress and success outside of the scale—and you'll stay more motivated for the long haul!

  • Say one good thing about yourself and your body every day. You'll come to believe it.
  • good article...the scale is just a tool- not God Almighty
  • didn't realize the scale would sway so much during menstruation cycle
  • good info for sure
  • Nice article, thank you. Everyone needs to read this one.
  • I think that basically the article is just trying to tell you that if your are obsessive with the scale it can be a bad thing. They aren't saying you shouldn't use the scale. If it's Mayo clinic, they know way more then most of us put together and they are right that it's better to weight like every few days then doing it after every meal, exercise, etc. They are just saying there are better times to weigh. I used to obsess over it and it just frustrated me when the numbers were not changing. Just saying that it's a good article. Everyone is going to do it their own way and that's ok, but let's don't discredit the article because it's from a very reputable source!
  • Honestly, I do not use the scale at all. I go by how my clothes are fitting. I think I too have IBS and my digestive system is way off since I've had my Gall Bladder out. I don't have normal bathroom situations. I guess that is the best way to put it without sounding inappropriate. This did not happen the first 2 years after my surgery, but then came on with a vengeance. You would think when this happens I would drop 10 lbs right off the cuff but that doesn't happen. I am actually gaining weight, but I know most of mine is due to the fact I have not been watching what I eat. I am in my 40's and when you reach your 40's and you do high intensity workouts you don't burn near the calories you use to. At least not according to my heart monitor that I wear when I work out. So I have to really watch my food intake. I try and not go above 1500 calories but have been trying to shoot below it since the beginning of the new year. So yes in my opinion the scale is still a good thing, but I think that there are definitely others ways to measure progress!
  • Okay, I'll be the one to mention poop. I have irritable bowel syndrome alternating, so I have to consider how much I have "on board." Since developing IBS, I've noticed some odd scale fluctuations that I suspect are related to the disease. I have learned to ignore these fluctuations. Additionally, the scale may even have a friendly day, and severe intermittent bloating will make my pants tight. During that situation, I have to remember that I'm doing my program, and that the inches bloating cause are not indicative of failure. If someone is a frequent weigher, I would recommend learning how to calculate the mean, median, and mode of their recorded weights. Mean is the average of the data, median is the number at the middle of the data set, and mode is the most frequently reported number in the data set. Mode, for example, would let me know how often I stay at a given weight in my data set. I find these numbers more heartening and supportive than just watching daily fluctuations.
    After eating out -- because most restaurant foods are high in sodium which leads to water retention!

    After a heavy carbohydrates intake day -- because carbs absorb water!!!

    It's hard not to fret, @SAROJARUN1. Even if one knows one's eaten a bit more salt or carbs than usual, or something like that. Seeing a 1 lb. increase on the scale the next day can make one feel like one is a failure. The article above can help to ease the mind, but only if one is sure that one has still been eating a caloric deficit overall.
  • Sometimes you loose inches, but your weight is constant. IT IS OK. Please do not worry.
  • I have weigh the same since March 1....It's very discouraging . I have been on a iet of 1200-1300 calories a day and have not cheated once. I have lost 67 lbs since Sept 1.
    Anyone have any ideas for me??
  • #8 After surgery. Most people I know are bloated after surgery.
  • I weigh myself every morning, naked (no need to worry about different clothes adding different weight). I realize my weight is going to fluctuate a little throughout the week. If I'm up a couple ounces, I adjust my eating plan for that day to stay on the low end of my calorie range and drink more water. If I've lost weight, it gives me motivation to keep doing what I'm doing. Either way, weighing in daily (for me), helps me along. My scale is just a tool to help me. It's not punishing me.
