quality better than quantity; what science says about mass

On the bright side: an underestimated fact, that you did detox and you don't know what future problems you have prevented by your 3 fasts thus far.
On the bright side: your cyst did not grow for a long time.
Health is always more important than looks. Looks can be very misleading. More mass doesn't mean more health. Football stars have one of the highest morbidity profiles for example, even though they have considerable amount of muscle. "The more of you there is, the more risk of ANY disease" - even for muscular builds. Quality is always better than quantity as far as body mass is concerned. New mutations that the immune system constantly deals with are a ratio of the existing number of cells. The more mass - the more cells, the more mutations.
I remember you saying not having considerable risk factors. I think otherwise : anyone who had lived in a Western country, had pesticide laden food, fluoride containing water etc is at risk for many things. Every 3rd American living now will be diagnosed with cancer at some point of their life.
Not to mention all the other pollution and deficiency problems ... plus the stress/anxiety related ones.
