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.
