"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.
“Everyone's weight fluctuates throughout the day, and especially from morning to night,” says dietitian Anne Danahy, MS, RDN. “The average change is 2 to 5 pounds, and it's due to fluid shifts throughout the day.” If you see fluctuations of less than 5 pounds, you needn't worry.
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').
If you weigh yourself at night, you're going to weigh more than you actually do, according to Discover Good Nutrition. Weigh yourself first thing the mornings, after your body has had a full night to digest your food. Otherwise, you'll be seeing higher numbers that don't correlate to all of your hard work.
How Much Does Your Weight Fluctuate From Morning to Night? Weight-loss statistics show on average, daily weight can fluctuate from 1 to 2 kilograms (2.2 to 4.4 pounds), per a July 2017 article in Physiological Reports.
Water retention
If your body notices it doesn't have enough water to do what it needs to do, it will hold onto it. Hormones are one of the causes of water retention, but there can be other factors. Even drinking too little water or eating super-salty foods can cause us to retain water.

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.
The average adult's body weight fluctuates between 1–2 kilograms (kg) or 2.2–4.4 pounds (lb) over a few days. Numerous factors influence a person's body weight. Individuals have no control over some factors, such as their genetics, age, and gender.
Clothing. Wearing clothing while weighing yourself can add up to two pounds—more if you're wearing shoes. Again, this isn't a big deal if you consistently weigh yourself wearing the same thing, but since our clothes vary with our moods and seasons, it's best to go without when you step on the scale.
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.
Typically, you weigh more after eating. You'll usually weigh less after strenuous physical activity because of the water you've lost through sweating. This is why one of the best times to weigh yourself is in the morning before you've eaten or exercised.
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.
First things first: It's totally normal for your weight to fluctuate 1-2kg in a day. Ever so often, patients come to me, saying: “I've tried several strict diet programmes and yet things go wrong.
Yes, You Do Lose a Little Bit of Weight
“Most stool weighs about 100 grams or 0.25 pounds. This can vary based on a person's size and bathroom frequency. That said, poop is made up of about 75% water, so going to the bathroom gives off a little bit of water weight,” says Natalie Rizzo, MS, RD.
You Ate a Big Meal Recently
It's just downright mean to weigh yourself after you just ate a big meal. According to the Mayo Clinic, food can take up to eight hours to pass through your digestive system, which can cause you to retain a little extra weight until the process has ended.
Transitioning from a very low calorie and low carbohydrate diet to a low calorie and moderate carbohydrate diet often leads to a weight gain of 1-2 kgs in a matter of one day. This is mainly because of a sudden increase in the carbohydrate content which is stored along with water in the body.
It's usually the result of food or water intake
Your weight is determined by the number of calories you consume compared to the number of calories you burn. Eating a healthy, balanced diet on par with the number of calories your body uses daily may reduce your chances of significant weight fluctuation over time.
Water retention can make you feel bloated, which may add on to your weight. In the morning our stomach is empty and the body's water is lost through sweat, respiration and urination. Due to these factors, we feel lighter.
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.
Since you're not eating or drinking during the night (unless you get the midnight munchies), your body has a chance to remove extra fluids (that's why you pee so much in the morning when you wake up). So weigh yourself in the morning ... after you pee.
“Your skin is the largest organ in the body and absorbs fluid easily,” says Dr. Keith Kantor, a leading nutritionist and CEO of the Nutritional Addiction Mitigation Eating and Drinking (NAMED) program. “After a swim or a shower, your body can absorb 1 to 3 cups of water, increasing your true weight by a few pounds.”
Bloating, gut health issues and hormonal changes can make you hold onto more water weight. The water weight usually settles down after your period. If you are not regular, or your fiber intake has been inconsistent, this can be a reason why you gained weight overnight.
Yes totally normal. I always weigh myself in the morning before eating and after going to the loo as that's my lowest. By the evening and when dressed I'm 2-3kgs heavier. For me it's totally normal (and frustrating).
In studies which have investigated the normal changes in body weight in healthy, free-living individuals, a fluctuation of + 1 kg in consecutive days is common, and fluctuations of + 0.5 kg are very common.
