The human body is the best work of art. How much do you know about him?
An adult person consists of 7 octillion atoms (this is a figure with 27 zeros). It has enough iron in its body to forge a metal nail and enough carbon to make 900 pencils. Enough fat to boil 7 bars of soap and phosphorus to make 2200 match heads. In this case, the body is a variable. No wonder its mass changes throughout the day!
11 reasons for constant weight fluctuations
For those who want to lose weight, regular weighing is the norm. It helps to track the results and make timely adjustments.
But there is one problem — the weight changes during the day. Why is this happening and what value can be trusted? About the most common causes of weight fluctuations - Further!
1. Your nutrition
The ratio between the amount of calories that enters the body with food and what it spends is the main reason why a person loses or gains weight. If there is a deficit, a person loses weight, and if it is an excess, he accumulates “extra”.
Experts have calculated that in order for a person to lose 1 pound (454 grams), he must consume 500 kcal less every day than the body needs. And all this in one week!
2. The way you weigh yourself
To find out the exact numbers of body weight, it is not enough just to jump on the scales. It is necessary to create certain conditions. The floor must be perfectly level and firm, the measurement of the body must be made when the person is standing on two legs and his weight is evenly distributed on the support. The presence or absence of clothing on the body also matters.
Nuances in these conditions give completely different results. And even if the values differ slightly, this is enough to draw wrong conclusions about the processes that occur in the body or about the effectiveness of the diet.
3. The scale you are using
Weigh yourself in the doctor’s office and immediately upon returning home. What values can be trusted, because the numbers are different? It turns out that the most accurate electronic scales. However, even they do not interfere with checking using reference weights.
And before weighing, do not forget to reset the scale of the device!
4. Time of day
The best time to get an accurate body weight is definitely in the morning. Immediately after waking up, but after you go to the toilet. Keep in mind that after breakfast, and even more so, lunch and a couple of snacks, the values on the scales will be different!
Did you know?
There are 99 more bones in a child’s body than in an adult’s body. Newborn babies have 305 bones, while adults have only 206.
5. Fitness load
Some athletes after an intense workout can lose 6 to 10% of their weight. And it is a mistake to think that this is fat (as beginners think). Most of what is lost is water, which leaves mainly through sweat.
Of course, after a morning set of exercises, your losses will not be so significant, but it is important to keep in mind that they are not uncommon!
6. Your health
Diabetes, heart failure, and even the common cold can affect your weight. If a person has lost his appetite and gains or loses water, the scales may move in one direction or another.
Be sure to talk to your doctor about changes in your body that are not typical for you.
Did you know?
Scientists have calculated that the average person can distinguish about a trillion odors. At the same time, the sense of smell is much more accurate and sharper than sight. The human eye distinguishes “only” 10 million colors.
7. Medications you take
Many medications, including anti-inflammatory drugs, antihistamines, or opiates, can cause rapid weight loss. Other drugs, such as insulin, antidepressants, and some antiepileptic drugs, can cause a person to gain weight rapidly.
Therefore, to keep your finger on the pulse, you should always ask your doctor about the side effects of the recommended medication.
8. The habit of drinking plenty of water
One liter of water weighs approximately 998.5 grams. This means that if a person drinks it and does not play sports, the scale arrow will go to the right.
However, experts warn that a sufficient drinking regime in the long run contributes to weight loss, not weight gain. In addition, thanks to him, the skin looks healthier, younger and more radiant.
9. Moisture deficiency
Studies have shown that 55 to 75% of an adult’s body is water. A lack of life-giving moisture will certainly affect his health: severe headaches, loss of strength, clouding of consciousness, difficulty concentrating, dry skin may occur. In addition, a person may suddenly lose weight.
If you are not drinking enough water, and you are experiencing these symptoms, it’s time to think about correcting your drinking regimen.
Did you know?
The human brain accounts for 2% of the total body weight. At the same time, it requires up to 20% of oxygen, which enters the blood.
10. Hormonal changes
When a woman’s body is preparing for menstruation, the change in hormone levels during this period often causes fluid stagnation. Many of the fair sex notice that their breasts and belly are getting bigger. After the end of menstruation, the weight will naturally move in the opposite direction.
11. Amount of sleep
Research shows that how much or how little a person sleeps can change their body weight. So, after a sleepless night, he may feel more hungry than usual (including due to increased levels of the stress hormone cortisol and the hunger hormone ghrelin), therefore, eat more. This can cause overeating during the day and weight gain in the late afternoon.

Our body consists of thirty trillion cells and is calculated by the formula:
MT u003d PZHT + SMM + SM + MO,
- where MT — body mass,
- PVT — the mass of the subcutaneous fat layer together with the skin,
- SMM — skeletal muscle mass
- CM — the mass of the skeleton,
- MO is the mass of the remainder.
Moreover, about 60% is water, including the contents of the intestines, bladder, fluid retained in tissues or edema due to malnutrition and cardiovascular disorders. Weight really fluctuates between 1–3 kg per day and there are certain reasons for this:
- The amount of food and liquid consumed. The time of day when eating is important: either it will turn into useful vital energy and burn out during the working day, or it will accumulate in “deposits”.
- Number of visits to the toilet per day.
- Salty food leads to water retention in the body in the proportion of 1 g/100 ml.
- Carbohydrates accumulate in the form of glycogen, which regulates fat metabolism, and this is weight gain — 1 g / 3 ml of liquid. An unexpected fact: an attempt to intensify training from a habit leads to muscle swelling and weight gain. Muscles are heavier than adipose tissue and there is no direct correlation between weight and volume.
- The menstrual cycle in its second phase explains weight gain from 3–5 kg due to the retention of salt by the female hormone estrogen.
- Stress. Against the background of stress — an increase in the production of the hormone cortisol, you can both get better and lose weight.

Some people who want to lose weight weigh themselves several times a day. And they can notice fluctuations. For example, in the morning the weight is one kilogram less than it was yesterday, and in the evening the figure is again at the same level. At such moments, it seems that proper nutrition and training do not bring results.
I want to quit everything and go back to my old way of life. Do not rush to get upset and stop the path to harmony.
An increase of 1–2 kilograms per day does not mean that fat deposits have formed. The process of fat accumulation is quite complex. Even if you eat according to the needs of the body, by the evening the weight may be more than in the morning. There are the following reasons for this:
Stress. During stress, the body is reluctant to say goodbye to extra pounds due to increased levels of cortisol (stress hormone). If in the morning you got up in a great mood, and by the evening you were pretty nervous, the weight can go up.
Fluid retention. Eating salty foods, alcohol and sweets, lack of sleep and too hot weather cause fluid retention in the body. It is because of her that by the evening there is an increase in weight.
Power training. After active work with a barbell or dumbbells, microcracks form in the muscle fibers. As a result, muscle volumes increase, edema appears. A person can observe that the weight has gone into plus.
Eating. While food is digested and passes through the digestive tract, weight can be added. But this does not mean at all that extra pounds automatically stick to the body. Calories from food go to the working processes of the body. When eating food for hunger and before it is satisfied, after a while you will again notice a plumb line.
Premenstrual syndrome. Some women notice a weight gain of 1 to 3 kilograms before the start of the cycle. Moreover, the weight appears as if from the air. Such changes are normal and not terrible. They occur due to fluid retention and hormonal changes.
There is also the opposite situation, when the figure on the scales decreases in the evening. Especially often this happens in the first week of weight loss. For example, when switching to intuitive eating. The body gets rid of toxins and excess water during the day, which can be immediately seen on the scales.
To see the general trend, it is better to focus not only on the arrow of the scales, but also on the volumes of the body. You can weigh yourself at the same time, once a day, and do it better on an empty stomach and after going to the toilet. Remember that the body is a fairly complex system and changes in weight during the day are normal.

Jumps in body weight during the day are due to a change in the amount of fluid in the body, which in turn is due to the circadian rhythms of the release of various hormones and mediators, the rhythms of the activity of various organ systems, the nature of food, and the frequency of its intake.
In the morning, adrenocorticotropic hormone is active, which increases the release of cortisol and a certain amount of catecholamines (adrenaline, norepinephrine). The maximum daily peak of cortisol accelerates our metabolism, and therefore the activity of the excretory system — the body actively gets rid of water. Adrenaline activates lipolysis — actively “burns” fat. In the morning we are as thin as possible.
By evening, metabolism slows down due to a decrease in cortisol levels and the activity of the thyroid gland, the hormones of which are responsible, among other things, for the metabolic rate. Carbohydrates retain water (about 1 gram of carbohydrates 4 grams of water), sodium retains water, dairy products cause fluid retention in many, cutting down on the drinking regimen reduces the activity of the excretory system and can, on the contrary, cause fluid retention.

As you know, the human body up to 70% consists of water, that is, in principle, it is a very fluid substance. During the day, the main parameters of weight change are set by sleep, meals and excretion processes, as well as physical activity.
After a night’s sleep and a morning trip to the toilet, body weight is usually the lowest, since the body has not taken food for a long time, had the opportunity to carry out a long metabolism and remove all excess as much as possible.
Further fluctuations are relatively individual as they are related to personal preference, but in any case the weight increases after eating and drinking, but decreases after each use of the toilet or active sweating as a result of exercise or high ambient temperature (hot day or stay in the sauna).
In part, weight also changes due to gas exchange in the lungs, as well as biochemical reactions in cells, but these fluctuations are too small. As a result, a person’s weight by the evening will still be the maximum for the day, unless he is intentionally starving.
Remember that the body is a flow, therefore, in principle, it cannot have an absolutely fixed weight.
