In-Depth Information
cholesterol (TC), high-density lipoprotein (HDL)-cholesterol, and triglyceride (TG)
levels were determined by using an automatic clinical analyzer (BPC Biosed srl.,
Italy). Serum low-density lipoprotein (LDL)-cholesterol level was calculated from
serum TC, HDL, and TG levels (Friedewald et al.
1972
) .
Serum adiponectin, leptin, and homocysteine levels were determined by enzyme-
linked immunosorbent assay (ELISA) kit, radio immune assay (RIA) kit, and enzy-
matic method in Samkwang Medical laboratories (Seoul, Korea), respectively.

Statistical Analysis
Experimental data are expressed as mean ± SEM. Statistical Package for the Social
Sciences (SPSS) for windows version 17.0 was used for the analysis. Differences
between groups were compared with the Mann-Whitney test. The correlation
among serum taurine and adipokine levels, and body compositions was analyzed
using Spearman's correlation coefficient. Differences were considered statistically
significant when the calculated p value was less than 0.05.

Results and Discussion
12.3.1
General Characteristics
General characteristics of the subjects are shown in Table
12.1
. The average of age
was 20.8 years. Eleven subjects (61.1%) lived with family, and 10 subjects (55.6%)
spent 210,000-400,000 Korean won (approximately US$180-$343) for pocket
money per month.

Body Composition
Changes in body composition of the subjects between before and after human body
weight control program are presented in Table
12.2
. Average body weight of the
subjects was 60.3 kg and average BMI was 23.5 kg/m
2
before they joined the pro-
gram. According to the fourth Korea National Health and Nutrition Examination
Survey, average weight of 19-29-year-old women was 55.5 kg. Because our sub-
jects wanted to lose weight, the average weight of our subjects was higher than that
of the similar age Korean women.
After the 8-week body weight control program, the average weight and BMI
were reduced to 57.3 kg (
p
< 0.001) and 22.5 kg/m

(
p
< 0.001). Body fat mass and
