    Abstract:
    Low-energy diet is highly recommended for obesity treatment. However, after success at the beginning some in some patients weight gain occurs. This study was aimed to evaluate changes in body weight and dietary intake in overweight and obese women during 1 year of a balanced low-energy diet. The study group comprised 70 women, aged 47.3, BMI 37.5 kg/m2. The balanced 1000 kcal diet was recommended. Body weight measurement, body composition assessment by BIA and dietary assessment were performed at entry and every 2 months of the study. Women were divided in 2 groups: I--women with body weight reduction achieved after 6 and 12 months of treatment (n=38), II--women who lost weight in first 6 months and gained weight in the next 6 months (n=32). After 1 year treatment averaged body weight reduction in women was 11.9+/-8.6%. In women from group I body weight decrement was 16.4+/-11.2 kg (15+/-9%), and in women from group II 7.5+/-7.7 kg, (8.1+/-6.7%), respectively. Body fat mass decrease in group I after 6 and 12 months was 7.8+/-6.0 kg and 11.1+/-7.9 kg, in group II 6.4+/-5.3 kg and 5.2+/-5.5 kg, respectively. Women from group II consume more energy, carbohydrates and sucrose in months 6-12 than in first 6 months and more than women in group I (p<0.05). During 1 year in group I calcium intake and Ca/protein index increased statistically significant, and in group II decreased. Changes in energy and nutrients intake do not correlate with achieved results. After 1 year of a low-energy diet statistically significant reduction of body weight and body fat mass were stated. Increase in energy, carbohydrates, sucrose intake and decrease in calcium intake could contribute to weight gain in studied women.
