1.  Safety of herbal medicine in treatment of weight loss 
ARYA Atherosclerosis  2014;10(1):55-58.
BACKGROUND
Obesity is a common health problem in both developed and developing countries. There are many unconventional therapies, including herbal medicine, to treat this condition. Some people believe that herbal medicines are safe. This case and review is about adverse complication of treating obesity with some herbal medicine.
CASE REPORT
A 19 year old male with sever obesity (120 kg) used green tea (15 cups of green tea per day) and an intensive dietary regimen to lose weight. He lost 30 kg after 2 months. At that time, one day after usual exercise he suddenly lost consciousness due to left ventricular fibrillation.
CONCLUSION
Use of herbal medicine for weight reduction is not always safe. Moreover, for some herbal medicine the risk is sufficient to shift the risk-benefit balance against the use that medicine.

2.  The Relationship between Weight and CVD Risk Factors in a Sample Population from Central Iran (Based on IHHP) 
ARYA Atherosclerosis  2012;8(2):82-89 .
BACKGROUND
Atherosclerosis is one of the leading causes of mortality all around the world. Obesity is an independent risk factor for atherosclerosis and cardiovascular diseases (CVD). In this respect, we decided to examine the effect of the subgroups of weight on cardiovascular risk factors.
METHODS
This cross-sectional study was done in 2006 using the data obtained by the Iranian Healthy Heart Program (IHHP) and based on classification of obesity by the World Health Organization (WHO). In this study, the samples were tested based on the Framingham risk score, Metabolic Measuring Score (MMS) and classification of obesity. Chi-square and ANOVA were used for statistical analysis.
RESULTS
12514 people with a mean age of 38 participated in this study. 6.8% of women and 14% of men had university degrees (higher than diploma). Obesity was seen in women more than men: 56.4% of women and 40% of men had a Body Mass Index of (BMI) ≥ 25 Kg/m2. 13% of the subjects had FBS > 110 and13.9% of them were using hypertensive drugs. In this study, we found that all risk factors, except HDL cholesterol in men, increased with an increase in weight. This finding is also confirmed by the Framingham flowfigure for men and women.
CONCLUSION
One of every two Americans, of any age and sex, has a Body Mass Index of (BMI) ≥ 25 Kg/m2. Obesity associated CVD and other serious diseases. Many studies have been done in different countries to find the relationship between obesity and CVD risk factors. For example, in the U.S.A and Canada they found that emteropiotic parameters, blood presser and lipids increased by age(of both sexes). Moreover, another study done in China, which is a country in Asia like Iran, shows that BMI has an indirect effect on HDL cholesterol, LDL cholesterol and triglyceride. This data is consistent with the results of the current study. However, In China they found that this relationship in men is stronger than women, but our study reveals the opposite.
