NCT01005420 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2023-06-12

No results posted yet for this study

Summary

The purpose of this study is to evaluate the effect of blueberry powder on insulin sensitivity in obese, non-diabetic, and insulin resistant subjects. The investigators hypothesized that supplementation with blueberry powder will result in an increase in insulin sensitivity in obese subjects with insulin resistance.

Conditions

  • Insulin Sensitivity

Interventions

DIETARY_SUPPLEMENT

Blueberry Powder

The blueberry and placebo groups will be randomized to receive 45g of blueberry powder or control per day. Blueberry powder will be given as a smoothie to be consumed at the breakfast and dinner meals and an identical smoothie will be given as a control. The smoothies will be prepared in the metabolic kitchen and a week supply of frozen smoothies will be given to participants. Both the blueberry powder and control smoothie contain comparable energy and macronutrients.
