About this study

In plain language

This study tests how drinking whey protein, a protein from milk, twice a day affects blood sugar and insulin. It is for adults ages 50–70 with prediabetes or diabetes.

To examine the effects of twice daily whey protein consumption on blood glucose and insulin in pre-diabetic and diabetic individuals

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Are age 50–70.
  • Have a body mass index (BMI), a measure of weight compared with height, between 25 and 45.
  • Can understand the study and agree to take part.
  • Test negative for COVID-19 and/or have no symptoms.
  • Will avoid alcohol, marijuana, and CBD products during two separate 7-day study meal periods.
  • Have an HbA1c (a measure of average blood sugar) of 5.7–6.4% or 6.5–7.5%, or fasting blood sugar of at least 100 mg/dL.

Who can't join

  • Cannot or will not eat dairy protein, or have lactose intolerance (trouble digesting milk sugar).
  • Use insulin injections, GLP/GIP injections, or other medicines that reduce appetite.
  • Will not keep a detailed food diary or wear a continuous glucose monitor (CGM), a device that tracks blood sugar, for two separate 7-day periods and share the readings.
  • Have hemoglobin below 10 g/dL at screening. Hemoglobin is the protein in red blood cells that carries oxygen.
  • Had chemotherapy or radiation for cancer in the past 6 months, or have had surgery to bypass or reduce the stomach or intestines.
  • Are pregnant or breastfeeding, or have a long-term disease that causes inflammation, such as lupus or Crohn’s disease.
  • Use androgen hormones such as testosterone, growth-related hormones such as GH or IGF-I, or steroid medicines such as prednisone.
  • Will not stop protein or amino-acid supplements or go without food overnight, or have a health condition or medicine that the study team finds makes participation unsuitable.
