Is it bad not to eat as much during pregnancy?

ali
I am 16 weeks pregnant and I find myself not eating as much as I should. For example, I wake up around 11am... and I don't eat till like 2 or 3... how bad can it be? Sometimes just getting up to get something to eat is such a chore! Urrgh help. .. im guessing it's as a result of this that my belly isn't showing. The only time it shows is when I lie on my back. It pokes out but not as significant. Help...
