Replacement Meal: Effectiveness of a Soluble Powder Rich in Fibers and at Low Glycemic Index in Overweight but Not in Obese Patients

摘要

Active lifestyle and qualitative and quantitative diets are the best way to lose weight. In our study we have assessed the effectiveness and tolerability of a soluble powder rich in fibers and at low glycemic index and used, with a portion of fresh fruit, as replacement meal (for a total calorie intake ranging from a minimum of about 130 kcal to a maximum of 260 kcal) in 52 overweight/obese subjects of the outpatient clinic of the Italian National Research Council (CNR) of Rome already in treatment with a low-fat low-carbohydrates qualitative diet. The study was a parallel, prospective trial of two randomized sample groups, “intervention” (26 subjects) and “control” (26 subjects). After 8 weeks, the treatment based on the replacement meal has improved the results obtained through the qualitative diet alone above all in the overweight subjects: 11/16, versus only 2/16 in the control group, became ranged within normal weight. On the contrary, the majority of obese subjects didn’t change their BMI classification suggesting that, in case of obesity, a controlled quantitative correction with weighing food portions could be a better strategy than low-calorie replacement meal.
