You should step on the scale first thing in the morning. That's when you'll get your most accurate weight because your body has had the overnight hours to digest and process whatever you ate and drank the day before. And you should try to turn that step into a regular part of your routine.
Daily weight fluctuation is normal. The average adult's weight fluctuates up to 5 or 6 pounds per day. It all comes down to what and when you eat, drink, exercise, and even sleep. Read on to learn more about how these factors affect the scale and when to weigh yourself for the most accurate results.
For the most accurate weight, weigh yourself first thing in the morning. “[Weighing yourself in the morning is most effective] because you've had adequate time to digest and process food (your 'overnight fast').
Most researchers agree that it's best to weigh yourself first thing in the morning. That way, you're more likely to make it a habit and be consistent with it. Weighing yourself in the morning helps especially with age-related gains, which can be more difficult to control.
Exercise, eating habits, and even whether you drank any alcohol the night before can all affect the number on the scale. Generally speaking, though, you are going to weigh in with the greatest consistency in the morning when you have not eaten or participated in strenuous physical activity in several hours.
As soon as you bend down, the muscles in your body that do the bending also act to pull up the lower half of your body. So this reduces the pressure your body places on the scales, and make you appear to weigh less.
"We can weigh 5, 6, 7 pounds more at night than we do first thing in the morning," Hunnes says. Part of that is thanks to all the salt we consume throughout the day; the other part is that we may not have fully digested (and excreted) everything we at and drank that day yet.
“Your weight won't be consistent if you weigh yourself on Friday and Monday,” she says. “Many people have a different routine on the weekends. They might eat out more, drink alcohol or snack more. Compare that to Friday, if you've been eating consistently for five days, and you'll see a big difference.”
So while you probably already know that it's best to weigh yourself first thing in the morning — before you've eaten or used the bathroom — you should also add one more parameter to the list: before showering. “Your skin is the largest organ in the body and absorbs fluid easily,” says Dr.
Muscle is denser than fat, and as it is more compact within your body, as you gain muscle mass, you end up looking thinner, no matter your physical weight. So, if you've been doing a lot of strength training lately, it's likely this is the reason that you're looking fantastic but not dropping those numbers.
Why Does My Weight Fluctuate So Much? Since many people can't eat enough in a day or two to actually gain 5 or 10 pounds, if you notice a dramatic increase on the scale, chances are it's due to water, says Anita Petruzzelli, M.D., owner and medical director of BodyLogicMD.
Most significantly, your body is dehydrated because you haven't been consuming any liquids for several hours. So in the morning, you're carrying about 3-5 pounds less water weight than you are in the afternoon. So this really is the primary reason you weigh less in the morning.
You may think you weigh a certain number, but the truth is that hardly anyone weighs the same day after day. "In general, weight fluctuates up to 3-4 pounds daily due to water weight or lack of moving bowels, so I don't feel weighing oneself daily is necessary or a good measure of true weight loss," says Kessler.
You've gained muscle.
And here's an often overlooked fact: Muscle tissue is more dense than fat tissue. So as you gain more muscle and lose fat, you change your overall body composition, which can result in a higher weight, but a smaller figure and better health.
In some people, especially those who have been dieting or fasting, a meal high in carbohydrates, such as pasta or rice, can be stored as glycogen. Glycogen is stored with water, which causes an individual to gain water weight very quickly – as much as 2 pounds overnight.
Overeating one day will not have much impact on your weight, but it will surely leave you feeling bloated. You can have an extra slice of your favorite cheesecake occasionally, but do not make this your habit. The next day, return to your fitness routine and everything will be fine.
According to colon cleanse providers (colonic hygienists), an adult can have between 5 and 20 pounds of residual stool in their large intestine (colon), leading to health problems such as excess weight gain, fatigue, and brain fog. But scientific evidence doesn't support this myth.
Dehydration causes your body to retain excess water, which can lead to 5 pounds of weight gain overnight (5). When you feel thirsty and drink a lot of fluid at once, you'll absorb the extra fluid quickly and it shows up on the scale within 24 hours.
As you sleep, your body burns calories, causing you to lose between 1 to 4 pounds of your weight overnight; this weight loss can be regarded as temporary weight loss because you need to consume fewer calories than you burn to avoid weight gain.
Men, it seems, prefer to swathe themselves in heavier garments while women tend to adorn themselves more lightly. Men can lop off nearly 2.5 lbs to account for their clothing while women can only subtract around 2.
Weigh yourself before you have anything to drink or eat: Weigh yourself ONLY before munching on the first meal of the day, however small it may be. Also remember to not drink any fluids before you hop on the scale.
Body weight can shift throughout the week and even during the day. In fact, an average adult can lose or gain two to eight pounds over the course of a few days. There's a weekly rhythm to weight variation with higher numbers on the scale in the beginning of the week and lower numbers toward the end.
The Role of Glycogen
You may end up weighing more in the morning simply because your muscles are storing more glycogen. The same phenomenon happens in the opposite direction when eating low-carb. You can drive your muscle glycogen fairly low by eating a low-carb diet.
A person can't actually gain or lose multiple pounds of body fat or muscle in a day, but it is possible to retain or shed a few pounds of liquid. Diet — especially salt consumption — plays a major role in how much water our bodies hold onto throughout the day.
The length of time that it takes to lose water weight depends on how much water you're retaining, the cause of the water weight gain, and the action taken to lose it. If you have one high-sodium meal and then return to normal, healthy dietary habits, you'll likely return to your normal weight in 1-2 days.
