focus on prevention and cure rather than managing illness.
On this subject, I discovered that current studies seem to show that the human body has a kind of a fixed "quota of calories" to spend each day, whether you exercise or not. Tribes walking 9km per day were spending the same amount of calories than office workers glued to their seats.
This explains why workout does not make you lose weight: you just assign a bigger part of your quota to muscles, but the total calories consumed do not vary.
However, there is a huge beneficial side-effect: the body dispatches the remaining calories quota to all the organs and systems, that then spend them into useless, and most often bad functions: for instance our immune system may go "trigger happy" and spend this extra energy in attacking our own body via inflammation, allergies and auto-immune diseases.
Thus exercise is a way to prevent our body to misuse our daily calories spending quota.
