This study will test the hypothesis that a low-carbohydrate Atkins diet will prevent or at least minimize the metabolic consequences of androgen deprivation therapy (ADT).

Further study details as provided by Duke University:

Primary Outcome Measures:
  • The primary end-point will be differences in insulin sensitivity between the arms [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Measures will include other cardiac risk factors, overall body morphometrics, body composition as assessed by dual energy x-ray absorptiometry (DXA), and cancer control (PSA levels) [ Time Frame: 6 months ]

Enrollment: 45
Study Start Date: June 2009
Study Completion Date: October 2014
Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Atkins group
Men assigned to the Atkins diet will be asked to restrict carbohydrate intake to <20 grams/day. We will use an established clinical program directed by Dr. Eric Westman which implements this diet using a trained clinical nutritionist. No other dietary restrictions will be placed on the subjects. They will measure their urinary ketones at home weekly using urinary ketone strips. Subjects will meet with the nutritionist monthly during the 6 months of the study. Subjects in the Atkins arm will also be asked to walk at a brisk pace for 30 minutes a day, 5 days a week and will be provided a pedometer to measure the number of steps taken per day.
Behavioral: Atkins Diet
Patients are given an outline of the Atkins diet and are asked to follow it for 6 months
Other Names:
  • Atkins group
  • Cases
No Intervention: Control group
Subjects assigned to the control group will be asked to make no changes in their dietary habits. At the completion of the study subjects will meet with the nutritionist and receive standard nutrition AHA recommendations.

Detailed Description:
Androgen deprivation therapy (ADT) is the standard treatment for advanced prostate cancer. While a very effective anti-cancer treatment, ADT is associated with significant toxicity including but not limited to major metabolic disturbances including impaired glucose tolerance, insulin resistance, and weight gain. We hypothesize that limiting carbohydrates within the diet will prevent or at least minimize these consequences.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)

  3. Treatment with medications known to affect insulin or glucose levels (i.e. insulin, oral hypoglycemics, prednisone, etc.)
  4. Patient consuming a low-carbohydrate diet
  5. Medical conditions or co-morbidities that preclude participation in the protocol
  6. Vegetarians
