Studies are/were underway on stage IV folks to try and flesh out how effective exercise was for them at preventing recurrence following "curative" attempt surgery. It's definitely been proven for stage II/III folks to be one of the best ways to decrease your risk of recurrence. My personal, completely unfounded in science guess/theory is that exercise will also benefit stage III/IV patients, just not with the same magnitude of benefit. I enjoy exercise most of the time anyway, and I love endorphines and senses of goal-accomplishment, so I'm a bit of an exercise junky. I'd do it whether I have cancer or not. But, cancer may get me motivated to do that 6th day in a row when normally I might wuss-out for 5
As far as diet for stage IV patients goes, here's my opinion. Eat what you want, with as much attention to moderation as possible. Extremes on either side of the dieting world are not good for you. Having a diet of wings, beer, burgers, fries, and cake is going to be detrimental to your health even if you don't have cancer. You're gonna feel like a sloth. Going to the other extremes and cutting out every "bad" thing imaginable (red meat, fat, sugar, carbs) isn't going to save your life. In fact, going full-on raw vegan juicing crazy is probably going to make you feel weak-er as you'll lack protein necessary to repair cell growth damaged during treatments. If you've got 20, 50, 100+ lbs to loose, then OK, you can try and eat healthier to loose some of that weight. You'll probably end up feeling better and the emotional boost of that accomplishment is greater than many folks realize. If you're otherwise relatively healthy, there's no reason to go into any diet extreme.
It's OK to treat yourself to a vice now and again. Eating that steak dinner once a month... Not going to turn your cancer into an implacable killing machine. That ice cream cone will not stimulate your tumors to run amok. Don't feel guilty about eating something you enjoy once in a while. I've been doing it for going on 3.5 years now and I'm doing just fine
