This is a randomized, controlled, crossover study that includes two screening visits, one baseline visit, two 28-d test periods and an end-of-washout visit. A 2-week washout period will separate the two treatments. Subjects will be screened to identify metabolic syndrome and/or prediabetes at the screening visits. Eligible subjects will be randomly assigned to a test sequence (USDA/lean beef or lean beef/USDA diets) and the appropriate calorie menu within each test diet, which will be determined based on each subject's calculated energy needs for weight maintenance. Study foods will be dispensed, and subjects will be instructed to consume all of the foods in their entirety for the duration of each 28-d test period, and avoid consuming any additional food or drink items that has not been provided to them. Compliance will be assessed through a Food Deviation Log where subjects will record any non-study food/beverages consumed, and any portions of the study foods not consumed.
