Conform unei noi cercet\u0103ri, creierul interpreteaz\u0103 dietele repetate ca perioade scurte de foame, ceea ce determin\u0103 organismul s\u0103 stocheze mai mult\u0103 gr\u0103sime pentru viitoarele penurii de alimente \u015fi astfel s\u0103 acumuleze kilograme. <\/span><\/span><\/p>\n

Oamenii care pierd \u00een greutate treptat cel mult 1 kg pe s\u0103pt\u0103m\u00een\u0103 au mai mult succes \u00een men\u021binerea ulterioar\u0103 a greut\u0103\u021bii. Studii anterioare au sugerat c\u0103 dieta cu efect yo-yo<\/a> cre\u015fte riscul de deces prin boli de inim\u0103<\/a>. <\/span><\/span><\/span><\/span><\/p>\n

Studiul, publicat \u00een revista Evolu\u0163ie, Medicin\u0103 \u015fi S\u0103n\u0103tate Public\u0103, a fost condus de prof. Andrew Higginson de la Universitatea din Exeter \u015fi prof. John McNamara de la Universitatea din Bristol. Cercet\u0103torii britanici au folosit modelul matematic al p\u0103s\u0103rilor, care \u0219tiu c\u00eend hrana este din abunden\u021b\u0103 sau e greu de g\u0103sit, dar nu \u0219tiu c\u00eend se va schimba situa\u021bia. Ei au observat c\u0103 animalele r\u0103spund la penuria de hran\u0103 prin stocarea energiei \u015fi cre\u015fterea \u00een greutate<\/a>. Modelul lor demonstreaz\u0103 c\u0103, atunci c\u00eend produsele alimentare s\u00eent pu\u0163ine, la fel ca \u00een timpul unei diete, un animal va c\u00ee\u0219tiga \u00een greutate<\/a> \u00eentre perioadele de penurie. <\/span><\/span><\/p>\n

\u201e\u00cen mod surprinz\u0103tor, modelul nostru prezice c\u0103, la cei care \u0163in diet\u0103, cre\u0219terea medie \u00een greutate va fi mai mare dec\u00eet la ceilal\u0163i<\/em>\u201d, spune prof. Higginson.<\/span><\/span><\/p>\n

Prof. McNamara adaug\u0103 c\u0103 modelul \u201earat\u0103 c\u0103 o cre\u015ftere \u00een greutate nu \u00eenseamn\u0103 c\u0103 fiziologia oamenilor func\u021bioneaz\u0103 defectuos. Creierul <\/a>lor func\u021bioneaz\u0103 normal, dar incertitudinea cu privire la aprovizionarea cu alimente declan\u0219eaz\u0103 c\u00ee\u0219tigarea \u00een greutate<\/em>\u201d. <\/span><\/span><\/p>\n

Cercet\u0103torii spun c\u0103 modelul lor arat\u0103 c\u0103 dorin\u021ba de a m\u00eenca cre\u0219te pe m\u0103sur\u0103 ce dieta continu\u0103, iar aceast\u0103 dorin\u021b\u0103 nu va disp\u0103rea dup\u0103 luarea \u00een greutate. Aceasta deoarece creierul crede c\u0103 perioade de foame<\/a> pot ap\u0103rea \u00een continuare. <\/span><\/span><\/p>\n

\u201eCel mai bun lucru e s\u0103 sl\u0103be\u015fti constant<\/a>. Munca noastr\u0103 sugereaz\u0103 c\u0103 a m\u00eenca doar cu pu\u021bin mai mult dec\u00eet trebuie, tot timpul, \u015fi a face exerci\u021bii fizice,<\/a> este mult mai probabil s\u0103 v\u0103 ajute s\u0103 ajunge\u0163i la o greutate s\u0103n\u0103toas\u0103 dec\u00eet dietele cu pu\u0163ine calorii<\/em>\u201d, crede prof. Higginson.<\/span><\/span><\/p>\n

Se recomand\u0103 reducerea aportului caloric cu 500-1.000 de calorii pe zi, pentru a pierde 1 kg pe s\u0103pt\u0103m\u00een\u0103. Odat\u0103 ce se atinge o greutate s\u0103n\u0103toas\u0103, trebuie s\u0103 te bazezi pe o alimenta\u021bie ra\u0163ional\u0103 \u0219i activitate fizic\u0103 pentru a men\u021bine greutatea pe termen lung. <\/span><\/span><\/p>\n

Chiar si o pierdere \u00een greutate modest\u0103 va conferi beneficii de s\u0103n\u0103tate, cum ar fi ameliorarea tensiunii arteriale, a colesterolului <\/a>\u0219i a zaharurilor din s\u00eenge. <\/span><\/span><\/p>\n
