Hi,
If you want to pursue PG in Nutrition and dietics, for this you will first have to a diploma of nutrition and dietics, and then you can apply for PG in Nutrition and dietics.
Good luck.

Yes, you can go for a nutrition course, but you will have to do your graduation all over again, as you start back from B.Sc, which is an undergraduate degree. So, if you feel you are not satisfied with B.Tech and now want to switch over to nutrition, then sure go ahead and live your dreams.

No, you cannot pursue executive MBA with 4 years of industrial experience, because they want 5 years' experience.
Good luck.
