This study aimed to evaluate the effect of low caloric diet on weight loss and improved cardiovascular risk in obese women's. The research was done on 20 respondents of Egyptian women's ranging between (30-50) years old and they have different obesity. They were divided into three groups A, B and C depended on the body mass index (BMI) and they were under experimental diets having low calories (1200-1500 kcal/day) for three months. Waist and hip circumference were measured before starting and after three months. Blood samples were also collected from the respondents and were analyzed for triglycerides, total cholesterol, low density lipoproteins (LDL) and high density lipoproteins (HDL). Results indicated that waist circumference, hip circumference, weight and BMI of all samples decreased significantly at the end of the experimental period in the different three groups as compared to beginning study. Moreover, this decrease was more pronounced for the group C which have the highest body measurements and body mass index at the starting of the experiment. Also, triglycerides, total cholesterol, HDL and LDL were decreased at the end of three months. The decrease was significantly in triglycerides and non-significant in HDL. So, it could be concluded that consuming controlled deities having low calories contents were effective for obesity treatment and decrease cardiovascular risks.
