Cancer Survivor, Overweight
Conditions
Brief summary
This randomized phase II trial will enroll overweight cancer survivors. Subjects in both groups will be educated to follow a diet pattern similar to what is recommended by the Dietary Guidelines for Americans and the American Institute for Cancer Research (DGA/AICR) but one group will also receive 18 ounces of lean beef for incorporation into a healthy diet. Subjects will be encouraged to exercise regularly and activity will be monitored throughout the study. Nutrition and exercise may help cancer survivors successfully maintain improved dietary patterns, body composition, and physical activity efforts and consumption of beef may favorably impact lean body mass and specific nutritional outcomes.
Detailed description
PRIMARY OBJECTIVES: I. To determine the feasibility and compliance with a the Dietary Guidelines for Americans/American Institute for Cancer Research (DGA/AICR) healthy dietary pattern and a beef + DGA/AICR healthy dietary pattern in cancer survivors. II. To determine the impact of dietary interventions on body composition, clinical outcomes, and physical performance. III. To quantify the impact of the two dietary interventions on cardiometabolic biomarkers of health. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive DGA/AICR-based dietary intervention for 6 months consisting of 12 education sessions over 60 minutes every other week, fruit, vegetable, and herb harvesting 1-2 times per week for 2 hours, wearing a FitBit during physical activity, and remote health coaching over 10 minutes for 12 weeks. ARM II: Patients receive DGA/AICR-based dietary intervention as in Arm I and consume 11-18 ounces of lean beef each week for 6 months. Clinical and physical activity assessments will take place at baseline, after the intervention and at 12 months.
Interventions
OTHERDietary Intervention
Participants randomized to the DGA/AICR group will receive plant-based diet education, garden access and health coaching for 5 months. The sessions are offered every other week.
BEHAVIORALExercise Intervention
Participants will wear a FitBit every day and monitor daily physical activity.

DIETARY_SUPPLEMENTNutritional Intervention
Participants randomized to the beef group will receive 11 to 18 ounces of frozen lean beef each week for home preparation, in addition to DGA/AICR diet education, garden access and health coaching.

Inclusion criteria
* Have a body mass index (BMI) \>= 25 kg/m\^2 * Be non-vegetarian/non-vegan, and have no concerns with beef consumption * Have completed active curative therapy for cancer within the past 36 months (i.e., surgery, chemotherapy, or radiation); ongoing hormone therapy is acceptable * Voluntarily provide consent, Health Insurance Portability and Accountability Act (HIPPA) authorization form, and consent from primary care provider (PCP) or treating oncologist * Not be planning to travel for more than 3 consecutive weeks during the intervention period * Agree to refrain from all nutritional supplements, herbal supplements, and botanical supplements aside from those prescribed by a physician for the duration of the study
Exclusion criteria
* Are cognitively unable to consent or have physical or mental limitations that would prevent full participation in the program * Are vegan or those unwilling to consume 11-18 ounces (oz) of beef per week * Have pre-existing medical conditions that preclude unsupervised physical activity (i.e., severe orthopedic conditions, impending hip or knee replacement, paralysis, unstable angina, dementia, recent history of myocardial infarction, congestive heart failure, pulmonary conditions requiring oxygen, or hospitalization in past 6 months) * Have had cancer treatment that significantly impacts digestion, metabolism, or food intake (e.g., surgical loss of esophagus, stomach, or colon, pancreas dysfunction, or brain surgery that alters cognition, etc.) * Report meeting the recommendations for physical activity (\> 60 minutes per day, most days per week) and already meet the majority of dietary guidelines as assessed by a telephone screener * Are prescribed medication that do not allow for increased intake of fruits and vegetables * Have recently (\< 3 months) started a statin or other lipid lowering medication; participants who report that they are changing a lipid lowering drug dose or drug type during the recruitment period will also be excluded; participants who have been stable on a lipid-lowering medication for at least 3 months may participate; well-controlled diabetics (type I or II) may participate * Have been diagnosed with active metabolic or digestive illnesses (i.e., Celiac disease, irritable bowel syndrome \[IBS\], renal insufficiency, hepatic insufficiency) * Are pregnant or are planning to become pregnant during the study
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Daily physical activity (steps per day) | up to 12 months | Each participants daily FitBit data will be downloaded to a secure spreadsheet |
| Adherence to either the DGA/AICR group or the DGA/AICR + Beef group | Up to 12 months | Participants will keep both 7 day diet records periodically through out the study as well as a daily log of beef consumption |
| Change in body composition | Up to 12 months | Change in body composition will be assessed by dual X-ray absorptiometry (iDXA) |
| Change in blood pressure | Baseline up to 12 months | Trained personnel will use a sphygomanometer to assess blood pressure |
| Change in body mass index (BMI) | Baseline up to 12 months | Weight and height will be combined to report BMI in kg/m\^2. |
| Change in dietary carotenoid intake | Baseline up to 12 months | Assessed by Raman spectroscopy |
| Change in blood carotenoids | Up to 12 months | Assessed by High Pressure Liquid Chromatography |
| Change in physical performance assessed by timed performance-related mobility tasks | Baseline up to 12 months | Physical performance will be measured using the 40 M walk test |
| Change in physical performance | Up to 12 months | Assessed by a standardized stair climb test |
| Dietary intake patterns | Up to 6 months | Will be assessed using diet logs maintained throughout the intervention and graphical food frequency questionnaire (FFQ). This FFQ automatically calculates the Healthy Eating Index 2010. Will use previous 30-day intake for all FFQs to assess dietary patterns. To determine protein balance, will use a 7-day diet record prior to a 24-hr urine collection. |
| Adherence to classes | Up to 12 months | Descriptive statistics will be generated using attendance forms |
| Change in fasting glucose | Up to 12 months | A fasting blood sample will be used to measure glucose at three time points |
| Change in lipoprotein profiles | Up to 12 months | A fasting blood sample will be used to assess serum lipoprotein profile |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Health related quality of life | Up to 12 months | Measured at all three time points using the Health Related Quality of Life (HR-QOL) questionnaire |
