My hunger might be definable as a cause outside my volition, and it might drive me to seek food, but the actions I take to do so - such as walking downstairs, going to the fridge, collecting the items together, and then cooking into a final meal are not mechanistic or predetermined. The ghrelin made me hungry, but it didn't make me perform all those actions.
The deterministic argument here of course is that your journey to the fridge is determined by the construction of your abode and your previous choices in appliances, and the meal is determined by the food you've purchased, the availability, transport, production of that food, the environmental and economic setting it was grown in, etc etc etc. A causal chain of specific material conditions predetermined your breakfast, which also include your state of being hungry.
But we're just rehashing the Free Will debate, rather than talking about any particular consequences for morality and/or ethics.
