Study Summary

Low glycemic index nutritional shakes have clinically shown to improve post-prandial glycemic responses in acute laboratory control studies. However, there is limited information on how replacing meals with low-glycemic index shake could impact glucose regulation in free-living adults consuming their own diets.

The present study aims to examine the impact of adding the SP Glucose-Assist shake to the breakfast of non-diabetic overweight and obese adults.

Subjects:

40 non-diabetic adults aged 25-65 years and body mass index ranging between 25-39 .

Protocol:

This is going to be a three-week study that will include a one-week self-selected diet, followed by two weeks of a breakfast supplement shake (standard process glucose assist) or control cereal oat breakfast.
