Do the words ANOREXIA NERVOSA mean anything to you? You weigh 105 pounds and you want to starve yourself thinner by eating a few ounces of cheese a day? That sounds like an eating disorder to me.

Don't trust your mirror. People with eating disorders see 'fat' on their bodies where it doesn't actually exist. Exercise will help tone your body, but you need adequate nutritional intake or you will end up doing yourself serious harm.
