简要总结
The purpose of this study is to evaluate the satiating effects of different functional yogurts enriched with soluble fiber or vegetable protein on overweight subjects (BMI ≥25 and <30 kg / m2).
Some studies have shown the contribution of high-fiber foods in the reduction of the cardiovascular risk. On the other hand, protein consumption could have a greater satiety potential compared to other macronutrients.
详细描述
A randomized, cross-over and double-blind pilot study with 3 study arms is being performed to evaluate the satiating properties of different functional enriched yogurts with soluble fiber or vegetable protein in a group of healthy overweight subjects.
The investigators included 12 participants (6 men and 6 women) between 18 and 55 years (BMI ≥25 and <30 kg / m2). All volunteers will be randomized into 3 study groups, and participants will receive the 3 different study products in order during the 3 experimental phases.

结局指标
主要结局
Change from Baseline Satiety Hunger Assessment
时间窗: Day 1, 8, 15
Visual Analogue Scale (VAS). 100mm horizontal line anchored at each end with the extremes of the subjective feeling to be quantified. Subjects are instructed to rate the sensation being experienced according to how they define the line. e.g., "not at all hungry" (0mm) and "as hungry as I have ever felt" (100mm). Multiple measures are taken at repeated time intervals described below.
