Measure
Caloric Intake Reduction
The intervention group will be seen by the kidney disease dietician at all clinical visits for the first 3 months (weekly for month 1, every other week for months 2 and 3). During months 2 and 3, in the weeks that the patients are not in clinic, they will receive telephone calls from the dietician. Thus the intervention involves weekly assessment for the first 3 months (in person or over the telephone). After 3 months, the patient will not receive any further active dietary intervention from the dieticians unless the patient wishes to continue using the dieticians advice per clinic protocol. caloric intake reduction: The caloric intake reduction arm will been seen by the kidney disease dietitian at all clinical visits for the first 3 months (weekly for month 1, every other week for months 2 and 3).
Standard of Care
The standard of care arm will receive dietary guidance per current University of Michigan Transplant Center policy, where a one time face-to-face visit is provided in the first month after kidney transplant and then as requested by the patient or referred by physician.

PRIMARY outcome

Timeframe: Post-Perfusion (Time 0 or Study Enrollment) and 3 months

Population: Because only one participant was involved in the entire trial, showing data could violate privacy interests. Further since the outcome measure was to compare the intervention against a control, given that there is no control arm, such a comparison is impossible.
