Satiety Profiles in Obese and Normal Adults After High-Carbohydrate Diet Ingestion

Abstract

Background : Obesity is one of the nutritional problems with an increase in prevalence every year. To avoid obesity, the selection of foods with the right nutrients is needed. The choice of foods with the right nutrients can affect the span of satiety. Carbohydrate is one of the macronutrients consumed in large quantities every day. Carbohydrate is important components that play a role in insulin secretion and postprandial blood glucose. Objective : To determine the differences of satiety profiles in obese and normal adults after high-carbohydrate diet ingestion. Methods : The study design was experimental with a pre-post group. The research subjects were 17 peoples about 20-23 years old were given two isoenergetic high carbohydrate meal tests. Satiety was measured using a Visual Analogue Score (VAS) questionnaire. Nutritional status is determined by BMI indicators. Data were analyzed using independent sample t-test and paired t-test. Results : The average of fullness in obese subjects (207.81±63.03), higher than normal subjects (141.97±37.65). The average of hunger, prospective food consumption (PFC), and desire to eat in obese subjects were 46.31±28.48; 40.08±20.83; 37.39±26.86 and the normal subjects were 54.80±15.92; 49.09±14.17; 46.20±16.56 respectively. The effect of satiety profile in obese subjects stopped at 150 minutes, faster than the normal subject’s which still exist until 180 minutes after ingestion. Conclusion : There is a significant difference of satiety profiles in obese and normal adults. Normal subjects have satiety effects longer than obese subjects after high-carbohydrate diet ingestion.
