The only realistic option is to eat somewhere where others won't see you: either in the privacy of your home or in a restaurant which offers private cabins. Otherwise you will always face people who find the practice off-putting.
If you're just a random tourist I wouldn't worry about it — no one is going to tell you off or expel you from the restaurant for eating with your hands, unless it's a super fancy establishment. If, on the other hand, you would like to behave like the locals — use the trusty fork and spoon.
