How far will be a weight reduction successful depends on numerous factors. We focused on genetic, nutritional, hormonal and psychobehavioral factors which may significantly affect weight loss. Among nutritional factors a special attention was paid to the role of intakes of dietary calcium and n-3 polyunsaturated fatty acids (PUFA). In subsequent studies the predictors of weight reduction. In a pilot study (study 1) the effects of dietary calcium intake in 208 overweight or obese subjects who underwent comprehensive weight management programme on weight loss were evaluated. The results of the pilot study showed that the weight loss significantly correlated with the changes in calcium intake - with increasing calcium intake higher weight loss was achieved. In the second study we investigated the effect of various forms of calcium supplementation on anthropometric, biochemical, hormonal and psychobehavioral parameters in a cohort of 67 overweight or obese perimenopausal women. We did not find any effect of calcium intake on weight loss. However, groups with calcium supplementation exhibited smaller decline in fat-free mass (FFM) compared with the placebo group. Calcium supplemented groups also demonstrated significant reductions in hunger scores. In the studies 3, 4 and 5 predictors of weight reduction were...
