Is it accurate for a fortune teller to eat two meals?

Not allowed. Fortune-telling is not a science, but a cultural tradition, which can only be used for people's entertainment and cannot be used as a basis for decision-making. Eating two meals means that a person enjoys two kinds of benefits at the same time, such as working in two companies at the same time or having two sources of income. If explained in contemporary spoken language, it can also be understood as having two girlfriends at the same time.
