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

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

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

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

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.
