Thanks to the revival of Marxism under Comrade Obama, we need to be exploring ways of improving our health because we will now all be working until our deaths due to collapsing nest egg investments.

I've posted previously on testosterone replacement therapy for males, a concept that is long overdue. It improves muscle mass and cognition, both of which are associated with higher productivity and longer life.

This appears to be an old link, but high fat, low carb diets may help arrest aggressive cancer growth by depriving them of glucose.

On the bodybuilding forums I read, the consensus appears to be that carbs should be eaten only after lifting or in the morning, when glycogen stores are low and insulin sensitivity is high (which is good). This amounts to fewer carbs consumed throughout the day, but has the effect of minimizing fat gain while still providing the carbohydrate energy needed for maximal effort. It appears that such diets may have other benefits as well.
