Editorial Comment: Effect of a low-calorie diet on 24-hour urinary parameters of obese adults with idiopathic calcium oxalate kidney stones

Obesity is often correlated with insulin resistance and diabetes. Obese people need to consume high fiber, high protein, low fat, and/or low calories food. In this report, the effect of the consumption of jelly containing porang glucomannan and inulin along with a low-calorie diet on the development of insulin resistance and fasting blood glucose (FBG) in obese adults were studied. A total of fifty-five volunteers of both sexes, aged 21 to 35 , were randomized to 3 groups: treatment 2 years, and body mass index (BMI) ≥23 kg/m group, placebo group, and control group (not given any jelly). All participants should consume 1500 kcal daily for the first 4 weeks and 1200 kcal/day for the next 4 weeks, including 2 cups of jelly (120 g per cup) per day. Jelly with porang glucomannan and inulin maintain a normal level of insulin resistance index of individuals with normal FBG and significantly suppress insulin resistance development in individuals with FBG above normal baseline. These results significantly correlate with the intake of fiber. The FBG was maintained under normal conditions in individuals with normal baseline and improved from diabetes to prediabetes category in individuals with above normal baseline.

Background. It is clinically important to determine the factors that increase fat oxidation and have potential to improve body composition in overweight and obese individuals. Thus, the aim of the present study was to compare the effects of a 2-day very low-calorie diet and 2-day zero-calorie diet on fat oxidation and prospective food consumption in overweight and mildly obese adults. Methods. Eighteen subjects (body mass index above 25 kg/m2) aged 19–33 years were tested under two conditions allocated randomly: 2-day zero-calorie diet with water provided ad libitum and 2-day very-low calorie diet. Appetite sensations, mood state, inhibitory control, and substrate oxidation were evaluated before and after each diet. Results. Greater increase in fat oxidation (p < .05) was observed after zero-calorie diet when compared to a very low-calorie diet. Results showed that both diets increased (p < .05) sensation of hunger and prospective food consumption, whereas no changes were observed in inhibitory control. Greater decrement for vigor (p < .05) was observed after zero-calorie diet when compared to a very low-calorie diet, whereas other mood states were not affected by it. Conclusion. Intermittent fasting with zero-calorie diet may boost fat oxidation to a greater extent when compared to very low-calorie diet and may assist with weight loss in overweight and mildly obese adults.
