It makes sense to me. Other ways to look at it could be that we can be addicted to behaviors, not just to substances, so maybe restricting eating can become addictive all by itself. Also, you could be addicted to the feeling of having an empty stomach, or the light feeling that comes from not eating heavier foods (there is a feeling of lightness associated with raw foods vegetarianism, which raw foodists promote, just saying that they feel better than they ever have before).
