Effect of 3-month treatment of obesity by low-calorie diet on anthropometric, health, and nutritional status for obese female individuals

Abstract

Background In the majority of obese patients, adjustment of the diet will be required to reduce calorie intake. In general, diets containing 1000-1200 kcal/day should be selected for obese patients. Objective The objective was to study the effect of treatment by low-calorie diet on obese female individuals for 3 months. Participants Forty obese female individuals (BMI΃40 kg/m 2 ) with ages ranging from 27 to 30 years were divided into two main groups: the nontreated group (n = 20) in which obese female individuals did not follow any diet and the treated group (n = 20) in which obese female individuals consumed low-calorie diet (LCD) containing 1200 kcal as 60 g protein, 165 g carbohydrate, and 33 g fats for 3 months. Materials and methods Food intakes, anthropometric measurements, follow-up weights, and blood samples were studied. Results After weight-loss phase, the anthropometric measurements (weight, hips, waist circumference, and BMI) for the treated group (consumed LCD) were decreased significantly. The mean serum total cholesterol (TC), triglycerides (TG), and low-density lipoprotein (LDL) in the treated group were decreased significantly (P Serum red blood cell, hemoglobin, hematocrit, and platelet in the treated group were decreased significantly at the end of weight-loss phase (P Conclusion Body weight reduction after LCD has a positive impact on anthropometric measurements and health status but has a negative impact on nutritional status because it lacks some of the nutrients.
