The goal of this clinical trial is to learn if Maqui berry gummy encapsulated (GMM) compared to non-encapsulated (GM) can improve glycemic response in overweight adults. It will also learn about the possible effect of serum antioxidant levels. The main questions it aims to answer are: Does GMM or GM low the glycemic response in overweight/obese subjects after consuming a carbohydrate rich food? Does GMM or GM increase antioxidant levels in overweight/obese subjects after consuming a carbohydrate rich food? Researchers will compare (i) a carbohydrate rich food, (ii) GMM + a carbohydrate rich food, (iii) GM + a carbohydrate rich food to see if Maqui gummy work to control glycemic and antioxidant levels. Participants will: Take a carbohydrate rich food, and/or Maqui gummy three times, one week apart Have blood samples collected and answer food questionnaires in each visit

Glycemia
Timeframe: Blood capillary samples will be obtained from participant's finger using glucose test strips (One Touch II) before consuming the white bread (time 0) and after consumption with or without the GCs (at 15, 30, 60, 90 and 120 minutes).
