Weight reduction and seasonal variation.

The purpose of the study was to establish whether there are variations in the efficiency of slimming treatment conducted in different seasons of the year. The clinical slimming treatment was undertaken over three years in 146 obese women. The efficacy of the treatment was determined by mean daily loss of body weight. The presented results show that weight reduction was season-dependent. The best results, ie the most marked loss of weight, were observed in spring, and the worst during winter.
