This study is for Veterans aged 55 and older who have certain types of cancer (bladder, colon, kidney, liver, pancreas, stomach, rectum, prostate, endometrium, ovaries, and uterus) and are having surgery soon. It aims to see if a special nutrition and exercise plan can help you stay strong and recover better after surgery. You would receive either a structured nutrition and exercise plan (including protein, Hydroxymethylbutyrate, vitamin D3, and multivitamins) or a standard nutrition and exercise counseling. Researchers will measure your walking ability (6-Minute Walk Test) before and after surgery to see if the special plan helps improve or maintain your physical function. The current recruitment status is unclear.
