Participants will be screened for approximate BMI, and medical history prior to recruitment. Participants under current treatment for cancer will be excluded. Participants with significant medical issues (such as unstable blood pressure, diabetes mellitus) will be asked to provide a medical release from their physician prior to participation. Participants currently in treatment for cancer will be excluded. In addition participants will not be enrolled until they have completed the physical assessment component of the study with blood pressure below 159/99 mm Hg (stage 2 hypertension), HbA1c below 10.0%, and total cholesterol below 300 mg/dL. If participants do not meet these standards a letter of permission to participate from a physician will be required.
