Overweight and obesity have reached pandemic extensions. The World Health Organization has recognized obesity being a disease which means it has to be treated and if/when possible also prevented. At first glance the solution
of the problem seems to be very simple, however, the rising prevalence of this disease proves that the problem is much more demanding and is connected with all pores of our lives. Through this work we tried to analyze some
epidemiological mathematical and/or simulation models related to the problem of obesity and accompanying processes regarding different goals of models’ usage. Of a special importance was the informativeness of modelling
results indicating social and/or economic burdens and the efficacy in estimation of the observed problems’ solution(s). It was detected that a great potential have multi-model descriptions which enable for each of the sub-processes
and/or sub-steps the presentation of only the most important causal interactions. Efficient and correspondingly evaluated mathematical description incorporating also control activities is still a challenge waiting for a
successive practical realization.
