Registration Number
NCT03286699
Lead Sponsor
University of Pittsburgh
Brief Summary

The goal of the research is to provide a first critical test of the novel scientific idea that a combined diet and exercise intervention may ameliorate shortening of leukocyte telomere length (LTL) in individuals with histories of successfully treated non-metastatic bladder cancer (BC) or colorectal adenoma (CRA) compared to a diet only intervention.

GroupInterventionDescription
DIETDietary InterventionThis group will be prescribed a Dietary Intervention that reduces energy intake by 500-1000 kcal/day and induces a weight loss of approximately 1-2 pounds per week during the intervention, with the weight loss goal individualized to each participant.
DIET-PADietary InterventionThis group will be prescribed a Dietary Intervention that reduces energy intake by 500-1000 kcal/day and induces a weight loss of approximately 1-2 pounds per week during the intervention, with the weight loss goal individualized to each participant. In addition, this group will be prescribed moderate-intensity Physical Activity Intervention that will progressively increase to the goal of 250 minutes/week.
DIET-PAPhysical Activity InterventionThis group will be prescribed a Dietary Intervention that reduces energy intake by 500-1000 kcal/day and induces a weight loss of approximately 1-2 pounds per week during the intervention, with the weight loss goal individualized to each participant. In addition, this group will be prescribed moderate-intensity Physical Activity Intervention that will progressively increase to the goal of 250 minutes/week.
