Ngati mwayeserapo kuchepetsa thupi, mukudziwa masiku kapena milungu yomwe mumadya zochepa akhakula. Kutembenuka, gulu limodzi lama neuron am'magazi limatha kukhala ndi mlandu pazomwe zimakhala zosasangalatsa, zomwe zimapangitsa kuti zikhale zovuta kutsatira, malinga ndi kafukufuku watsopano. (Kodi mwayesapo Njira 11 Izi Zotsimikizira-Kunyumba Kwanu?)

Inde, ndizomveka kuti kumva njala sikungakhale kosangalatsa. "Ngati njala ndi ludzu sizikumva kuwawa, mwina simungakhale pachiwopsezo chopeza chakudya ndi madzi," atero a Scott Sternson, Ph.D., wofufuza ku Howard Hughes Medical Institute komanso wolemba nawo kafukufuku.

Sternson ndi anzawo adapeza kuti, mbewa zikaonda, gulu la ma neuron otchedwa "AGRP neurons" -anasinthidwa ndikuwoneka kuti akukulitsa "zosasangalatsa kapena zoyipa" muubongo wawo wawung'ono. Ndipo Sternson akuti zawonetsedwa kale kuti ma neuron ophatikizirawa amakhalanso muubongo wa anthu.

Zingawonekere kuti kukhala ndi njala kungayambitse malingaliro "oipa". Koma phunziro la Sternson ndi limodzi mwa oyamba kufotokoza kumene malingaliro oipawa amachokera. Akuti ma neuron a AGRP amakhala mgulu la ubongo wanu lomwe limathandizira kuwongolera chilichonse kuchokera ku njala ndi kugona mpaka momwe mumamvera.

Chifukwa chiyani izi zili choncho? Sternson ndi gulu lake adawonetsanso kuti, pozimitsa ma neuroni a AGRP mu mbewa, adatha kukopa mitundu yazakudya zomwe mbewa amakonda komanso malo omwe amakonda kukacheza.

Kupanga mankhwala omwe amaletsa ma neuron a hangry awa kungakhale chithandizo chochepetsera kuchepa, akutero.(Kutengera kafukufukuyu pamlingo wina wongopeka, ngati mumakonda kudya kwambiri pakama panu kunyumba, ma neuron awa atha kukuthandizani kulimbitsa chikhumbo chanu chotsatira chizoloŵezi choipachi.)

Koma zonsezo ndi zamtsogolo, akufotokoza Sternson. "Pakadali pano, kafukufuku wathu amangopereka chidziwitso chazomwe anthu amadzukanso akamayesetsa kuonda," akutero. "Anthu amafunika kukonzekera ndipo amafunikira kulimbikitsidwa ndi anzawo kuti athane ndi zovuta izi."

Ngati mukusaka za kulondola pulani, kafukufuku akuwonetsa kuti a Jennie Craig ndi Oyang'anira Kunenepa ndi zakudya zabwino kuyesa. Kumwa vinyo wofiira (mozama!), Kumamatira ku nthawi yogona/kudzuka, ndi kutsitsa thermostat yanu ndi njira zabwino kwambiri zothandizira zolinga zanu zazakudya.
