Abstract:
OBJECTIVES: This study was conducted to investigate the effect of a 6-week low-calorie diet (LCD) program including high protein-low carbohydrate protein bar on weight loss, blood pressure, and blood lipid profile in 40 overweight women according to dietary compliance.METHODS: Subjects were 62 healthy overweight women (BMI ≥ 23.0 or body fat percentage ≥ 28%), aged 20~59 yrs who were provided a high protein-low carbohydrate protein bar (each 35 g, 154 kcal, protein energy %: 28.6%, carbohydrate energy %: 38.7%) as part of dinner for 6 weeks. Forty subjects who completed the whole diet program were categorized into high compliance (HC) group (days of eating protein bar ≥ 5 weeks) or low compliance (LC) group (days < 5 weeks).RESULTS: Energy intake significantly decreased from 1,867.5 kcal at baseline to 1,137.4 kcal at 6 weeks for the HC group and from 1,971.7 kcal to 1,362.2 kcal for the LC group, respectively. On the other hand, a significant increase in protein energy percentage was observed in each group (HC group: 3.5%, LC group: 2.2%). Both groups showed significant decreases in weight (HC group: 1.8 kg, LC group: 1.1 kg), BMI, fat mass, systolic blood pressure, total cholesterol, and LDL-cholesterol. Reduction of body fat percentage and diastolic blood pressure were only observed in the HC group.CONCLUSIONS: The inclusion of a high protein-low carbohydrate protein bar as part of a low-calorie diet for a short period can be effective to achieve weight loss and concomitantly improve blood cholesterol level without serious physiological side effects. More evident results can be achieved by eating a diet with low calorie diet including high protein-low carbohydrate protein bar for more than 5 weeks.
