HOW STRESS AND SLEEP CONSPIRE TO MAKE YOU FAT

Not so many people know that bad or short and insufficient sleep affects obesity and deposition of excess weight. Stress and hormones that it secretes also affect our weight and body. How, we’ll find out in the following text.

 

STRESS

What is cortisol? It is a hormone secreted by the cortex of the adrenal gland in response to stress, and the effect it has on muscle and body is only destructive. To make matters worse, cortisol increases blood sugar and thus the body “saves” fat. Of course, where would you least like to see – around the waist, thighs and so on. If we look at the cyclical rhythm of cortisol, then its concentration is highest in regularly waking up at 10am at 3pm at the beginning of a night’s sleep. Therefore, in these times is very important to bring high-quality nutrients. When the person who is training, cortisol is also at a very high level after training and government catabolic environment. To reduce this effect to a minimum after training should consume carbohydrates with high glycemic index (glucose, maltodextrin) to separate the insulin. This is important for two reasons: insulin acts contrary to cortisol (reduces blood sugar) and glucose, which under its operation into the station opens the “door” to the cell membrane to the building blocks (amino acids from whey proteins that are consumed together with coal hydrates) could rebuild the station. However, the period in which we have the opportunity to stop muscle catabolism and ensure rapid influx of amino acids and renewal energy resources (carbohydrates) is very short and includes the longest hour of the completion of the training.

 

SLEEP

In fact, if you do not sleep enough leptin – a hormone that controls appetite and affects the production of fat, will be decreases. Low levels of leptin give signals to body that there is a lack of food and increases appetite. This means that the brain receives a message that we need more food, and thus be grown. Most people need between six and eight hours of sleep one night. Studies show that good sleep may limit how many calories humans consume, and that “bad and short daily sleep” can lead to weight gain. If you tend to stay up late into the night and little sleep, these results may be particularly important for you. It turned out that those who going in the bad vary late and bring meals after 22h, get kilograms around stomach more than in the rest parts of the day.

KAKO NESPAVANJE I STRES UTIČU NA GOJAZNOST I ORGANIZAM

Malo ljudi zna da slab ili kratak i nedovoljan san utiče na gojaznost i taloženje viška kilograma. Stres i hormone koje on luči takođe utiču na naše kilograme i organizam. Kako, saznaćemo u sledećem tekstu.

STRES

Šta je kortizol? To je hormon koji luči kora nadbubrežne žlezde kao odgovor na stres, a efekat koji on ima na mišić i organizam je isključivo destruktivan. Da stvar bude gora, kortizol povećava šećer u krvi i na taj način u telo “sprema” masno tkivo. Naravno, tamo gde bi ga najmanje voleli videti – oko struka, na bedrima i sl.

Ako gledamo ciklični ritam izlučivanja kortizola, onda je njegova koncentracija redovno najviša kod buđenja, u 10:00 u 15:00 i na početku noćnog sna. Stoga je u ta vremena vrlo važno uneti kvalitetne nutrijente.

Kod osobe koja trenira, kortizol je isto tako na vrlo visokom nivou nakon treninga i vlada kataboličko okruženje. Kako bismo smanjili taj efekat na minimum, nakon treninga treba konzumirati ugljene hidrate visokog glikemijskog indeksa (glukoza, maltodekstrin) kako bi se izlučio insulin. To je bitno iz dva razloga: insulin deluje suprotno kortizolu (smanjuje nivo šećera u krvi), a glukoza koja pod njegovim delovanjem ulazi u stanicu otvara “vrata” na membrani stanice da bi gradivni elementi (aminokiseline iz proteina surutke koji se konzumiraju zajedno s ugljenim hidratima) mogli obnoviti stanicu.

Međutim, taj period u kojem imamo priliku zaustaviti katabolizam i osigurati mišiću brzi dotok aminokiselina i obnovu energetskih resursa (ugljenih hidrata) je vrlo kratak i obuhvata najduže sat vremena od završetka treninga.

NESPAVANJE

Naime, ako ne spavamo dovoljno nivo leptina, hormona koji kontroliše apetit i utiče na proizvodnju masnih naslaga, opada. Nizak nivo leptina signalizira organizmu da postoji nedostatak hrane i povećava apetit. To znači da mozak dobija poruku da je potrebna dodatna količina hrane, i na taj način se gojimo.

Većina ljudi potrebno je između šest i osam sati sna za jednu noć. Studije pokazuju da dobar san može da ograniči koliko kalorija ljudi unose, a da “loše i kratko dnevno spavanje” može dovesti do povećanja telesne težine.

Ako ste skloni da ostajete do kasno u noć i da malo spavate, ovi rezultati mogu biti posebno bitni za vas. Pokazalo se da se kod onih koji lezu kasno i unose obroke posle 22h kilogrami vise lepe za stomak nego u ostalim delovima dana.
