My father had inclusion body myositis, an autoimmune wasting disease that is usually fatal in 4 years. It got the jump on us in the first two years, but then I figured out that if you increase protein (cold-processed whey) and antioxidants, and induced higher HGH release (SomaLife gHP amino acids) we could just keep abreast of it even in a 70-year old.
When we added A*****ose AO to this equation he started gaining weight again! So it's been four years with an incurable, fatal illness and he's gaining.
This is a practical example, because certain foods he won't buy and eat just because they're good for him.
