Homeostasis and my Hypothesis on genetic predisposition for some people needing animal products and how they can adapt

I think because of my vast amount of research on weight loss, or rather, fat loss, and hanging around the vegan body building forum as well as building muscle, losing fat, and then having periods of staying the same (homeostasis), the theory of adaptation seems like common sense to me. There's so many tricks like varying your calories by 100 per day, having a carb fest on the weekend, and other ways to keep your body from adapting to the calories your taking. It also adapts quickly to the type of exercise, that's why muscle confusion and changing your routine is one way to keep the burning going. So is interval training and not just the same speed of biking and running. Lifting weights is the most important to getting a faster metabolism for life. Just doing aerobic will cause you to mess up your metabolism in the long term. You lose muscle doing only aerobics, especially if you are not eating enough calories to support it. So just blowing off my hypothesis is not a good idea, it really makes sense. Well, at least it does to me.
