Enriched Yogurts With Soluble Fibre or Vegetable Protein on Satiety

Pilot Study to Evaluate the Satiating Effect of Enriched Functional Yogurts With Soluble Fibre or Vegetable Protein in a Group of Healthy Overweight Subjects

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.

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.
