Eh, well, the technical answer is yes and no.
First, the no part: technically, if you are referring to altering the actual sequence of your genetic code, no, exericse and diet will not change
this. Every cell in your body contains a copy of your genome, except for erythrocytes. So, if you were to alter your genome, it would have to be
change in all of these cells. Things like cancer are local changes, and often aren't changes in the sequence at all, just irregular activation of
dormant genes.
Second, the yes part: if you are asking if the number/type of activated genes can be changed by diet and exercise, absolutely yes. While this in no
way indicates and actual change in your genomic sequence, it DOES reflect a change in repression/activation of certain genes with respect to your
environmental stimuli, such as food types, vitamin/nutrient intake, etc.
Hope this helps =).
