Kafukufuku wasonyeza kuti kupezeka kwa shuga kwapakatikati (12 h / tsiku) kumatulutsa zizindikilo zodalira makoswe, kuphatikiza kuchuluka kwa kudya, mu-opioid ndi dopamine receptor kusintha, mayendedwe amachitidwe ndi mitsempha yokhudzana ndi kusiya, komanso kuwalimbikitsa ndi amphetamine. Ma paradigms a "kunyansidwa," komwe kusiya chinthu kumapangitsa kuti munthu azidya bwino, amagwiritsidwa ntchito poyeza "kulakalaka" mankhwala osokoneza bongo, monga mowa.
Phunziroli linagwiritsidwa ntchito kuti lifufuze kugwiritsidwa ntchito kwa shuga pambuyo posiya kudya makoswe omwe amasankhidwa kuti azichita mwamphamvu. Gulu la kuyesera linaphunzitsidwa pa ndondomeko yokhazikika (FR-1) pulogalamu ya 25% glucose kwa 30 min / tsiku kwa masiku 28 komanso anali ndi mwayi wopita muzipinda zapakhomo pa 11.5 tsiku ndi tsiku. Gulu lolamulira linali ndi 30 min / day access to glucose m'chipinda chogwiritsira ntchito. Kenaka, magulu onse awiriwa analibe shuga kwa masabata a 2. Pambuyo pa nthawi imeneyi, ziweto zinabwereranso m'chipinda chogwiritsira ntchito. Gulu la kuyesera linayankha mochuluka kuposa kale lonse, ndipo limaposa kwambiri gulu lolamulira.
Pomalizira, tsiku ndi tsiku 12-h kupeza shuga, pamagwiritsidwe ntchito, kungabweretsere chisokonezo chomwe chimatha m'masabata onse a 2 kuti azidziletsa, zomwe zimayambitsa kudya. Pamodzi ndi zotsatira zammbuyo, zotsatira zotsalirazi zimagwirizanitsa chiphunzitso chakuti zinyama zikhoza kukhala zidalira ndi shuga pansi pazochitika zodyera.
