Brief Summary

RATIONALE: Calories and physical exercise may affect the risk of developing cancer. It is not yet known whether a low-calorie diet and/or physical activity program is effective in preventing cancer in participants at increased risk of developing colorectal cancer. PURPOSE: This randomized clinical trial is studying diet and physical activity in healthy overweight, obese, or inactive participants at risk of developing colorectal cancer.
