| Popis: | Background/Aim. Obesity is an established risk factor for numerous chronic diseases. The aim of this study was to investigate the effect of well-balanced different caloric restriction (CR) diets on anthropometric parameters and standard biochemical cardiovascular risk markers [lipid profile, glucose homeostasis and high sensitivity C-reactive protein (hs-CRP)] in overweight/obese females. Methods. Participants (age 20-40 years) were randomized into 3 different CR diet groups: the group I - restriction of 20% calories from baseline energy requirements, the group II - restriction of 50% calories from baseline energy requirements and the group III - alternating daily diets with 70%/30% restriction. The study lasted 42 weeks. Anthropometric parameters were measured at the start and after 4, 8, 20 and 42 weeks after dietary intervention beginning. Biochemical markers were determined at baseline and after 20 and 42 weeks from dietary restriction start. Results. Body weight, body mass index (BMI), waist circumference (WC) and body fat (in %), in the different CR diet groups significantly decreased after 42 weeks. Body weight was less 11 kg in the group I and 12 kg in the groups II and III. WC was reduced by 11 cm in the groups I and III and by 10 cm in the group II. Different CR diets had the same effects on body fat (a reduction of 15% of body fat). Total cholesterol decreased by 7% in the group I and by 8% in the group III. Low density lipoprotein (LDL) cholesterol decreased by 14% in the group I and by 13% in group III. There were no significant changes in total and LDL-cholesterol levels in the group II. The atherogenic index presented as trigliceride/high density lipoprotein (TG/HDL) ratio decreased by 0.22 in the group I, by 0.25 in the group II and by 0.32 in the group III. Various CR diets had the same effects on reducing the hs-CRP levels. Conclusion. Different CR diets with the same macronutrient content are equally effective in reducing body weight, WC and body fat, improve cardiometabolic risk factors and decrease level of proinflammatory hs-CRP in overweight/obese females. Uvod/Cilj. Gojaznost je faktor rizika od nastanka mnogih hroničnih bolesti. Cilj istraživanja bio je da se ispita efekat dobro izbalansirane ishrane različitih kalorijskih ograničenja na antropometrijske parametare i standardne biohemijske kardiovaskularne markere rizika [(lipidni profil, homeostazu glukoze, visoko senzitivni C-reaktivni protein - high-sensitivity C-reactive protein (hs-CRP)] kod predgojaznih/gojaznih žena. Metode. Ukupno 97 žena, između 20 i 40 godina starosti, konzumirale su uravnotežene, kalorijski različite restriktivne dijete, na sledeći način: I grupa (n = 37) - ograničenje 20% kalorija od osnovnih energetskih potreba; II grupa (n = 30) - ograničenje od 50% kalorija od osnovnih energetskih potreba i III grupa (n = 30) - naizmenična dnevna restrikcija od 70% i 30% kalorija od osnovnih energetskih potreba. Stepen uhranjenosti je određivan antropometrijskim merenjima na početku i nakon 4, 8, 20 i 42 nedelje od uvođenja dijeta. Biohemijski markeri analizirani su na početku i nakon 4, 8, 20 i 42 nedelje. Rezultati. Kalorijski različite restriktivne dijete dovele su do značajnog smanjena telesne mase, indeksa telesne mase (body mass index - BMI), obima struka (OS) i % telesne masti nakon tretmana od 42 nedelje. Telesna masa snižena je za 11 kg u grupi I, a za 12 kg u grupama II i III. Za 11 cm je smanjen OS u grupama I i III i za 10 cm u grupi II. Gubitak 15% ukupne telesne masti ostvaren je za sve vrste dijeta nezavisno od različitog kalorijskog unosa. Koncentracija ukupnog i (low density lipoprotein) holesterola (LDL-holesterola) snižena je za 7% i 14% u grupi I i za 8% i 13% u grupi III. Dijeta sa redukcijom kalorijskog unosa od 50% nije imala efekta na nivo ukupnog i lipoprotein niske gustine LDL-holesterola. Aterogeni indeks predstavljen kao odnos trigliceridi/lipoprotein visoke gustine (high density lipoprotein) - TG/HDL bio je manji za 0,22 u grupi I, za 0,25 u grupi II i za 0,32 u grupi III. Kalorijski različite restriktivne dijete dovele su do istog sniženja nivoa hs-CRP. Zaključak. Restriktivne vrste dijeta sa različitim kalorijskim unosom i sa istim procentom zastupljenosti makronutrijenata jednako su efikasne u smanjenju telesne mase, OS i % telesne masti, dovode do poboljšanja faktora kardiometaboličkog rizika i smanjenja proinflamatornog hs-CRP kod predgojaznih/gojaznih žena. |
