Low carbohydrate diet. Its effects on selected body parameters of obese patients

OBJECTIVE: This pilot study, which involved 13 obese patients, was conducted to determine the effect of a low carbohydrate diet on the body weight and other body parameters, including blood pressure and selected biochemistry indicators.

METHODS: The study was carried out in Naim Health Center, Bahrain during the period March 2002 to April 2002. Each individual was followed for 6 weeks while on a low carbohydrate diet, with careful monitoring during the study period.

RESULTS: Paired t-test showed statistically significant reduction of waist circumference (p<0.00) and body weight (p<0.00) of the sample population after 6 weeks from the commencement of the diet. The body mass index also showed statistically significant reduction during the study period (p<0.01). Furthermore, blood cholesterol level was reduced (p<0.012). Although there was a statistically significant decrease in the fasting blood sugar levels (p<0.01), the mean readings remained within the normal range of blood sugar levels. There were no statistically significant changes in the levels of urate, creatinine, urea, triglyceride, and in systolic or diastolic blood pressure readings (p>0.05).

CONCLUSION: Low carbohydrate diet could help in reducing body weight without any significant harmful effect.
