There was significant weight reduction between admission and six months after treatment 84.7+17.9 vs. 77.3+3.2kg (p<0.003). Significantly decrease in BMI before and after six months intervention 31.7+5.6 vs. 28.5+4.4 (p<0.003) was observed. The study showed more than 10% weight reduction after six months diet therapy (p<0.01).
