Cilj naše raziskave je bil, da raziščemo vplive nezdrave prehrane na telesno maso, telesno sestavo in obseg pasu. V raziskavi je sodelovalo 23 zdravih posameznikov, sedem moških in 16 žensk, s povprečno starostjo 37 ± 9,7 leta. Posamezniki so se sami razdelili v dve skupini, eksperimentalno in kontrolno. Eksperimentalna skupina je zajemala 11 posameznikov (štirje moški in sedem žensk), kontrolna pa 12 (trije moški in devet žensk). V eksperimentalni skupini so merjenci vsak dan zaužili 20 odstotkov dnevnega kaloričnega vnosa v obliki t. i. »nezdrave« hrane, medtem ko je bila ta hrana merjencem v kontrolni skupini prepovedana. Vsi so bili v kaloričnem deficitu (porabili so več energije, kot so jo vnesli) 2092 kJ (500 kcal) na dan. Raziskava je trajala tri mesece. Ugotovili smo, da so merjenci v eksperimentalni skupini izgubili več telesne mase (5,2 kg) kot merjenci v kontrolni skupini (3,9 kg). Ti podatki sicer niso bili statistično značilni. Merjenci v eksperimentalni skupini so izgubili tudi več maščobne mase (4 kg) kot merjenci v kontrolni skupini (2,6 kg). Izgubili so manj mišične mase (0,7 kg) kot merjenci v kontrolni skupini (0,9 kg) in več centimetrov v obsegu pasu (5,5 cm) kot merjenci v kontrolni skupini (3,3 cm). Med skupinama ni bilo razlike med deležem telesne vode. Pri vseh rezultatih ni bilo statistične značilnosti, razen pri deležu mišične mase. Dobljeni rezultati prikazujejo, kljub nekaterim pomanjkljivostim pri naši raziskavi, da trimesečno uživanje nezdrave hrane ne vpliva negativno na telesno maso, njeno sestavo in obseg pasu posameznika.

The purpose of our study was to determine the effects of junk food on body mass, body composition and waist circumference. Twenty three healthy adults with an average age of 37 ± 10 years participated in the study. The testees have decided for themselves which study group they wanted to be in, experimental or control. Experimental group included 11 indivuals (four men and seven women) and control group included 12 individuals (three men nad nine women). In the experimental group the testees had to eat 20 % of the daily caloric intake in the form of junk food every day, while the consumption of such foods was forbidden for the testees in the control group. Every individual was in a 2092 kJ (500 calories) deficit a day (meaning the energy output was greater than the input). The study lasted three months. The results showed that the experimental group has lost more body mass than the control group (5,2 kg and 3,9 kg, respectively). These results did not show statistical significance. The experimental group has also lost more body fat than the control group (4 kg and 2,6 kg, respectively), has lost less muscle mass than the control group (0,7 kg and 0,9 kg, respectively) and decreased waist circumference more than the control group (5,5 cm and 3,3 cm, respectively). There was no difference in body water and general well-being between groups. No statistical significance was found in any of these results, except in muscle mass percentage. Our results show, despite many flaws in our study, that junk food does not have a negative impact on body mass, body composition and waist circumference after three months.
