Actually, that is not entirely true. When you look at your hunger as an overall - 0 to 100 percent, "full" only makes up the top 10%. "Hungry" makes up a larger percent, but I'm not sure what percentage exactly.
For instance, a piece of bread raises your
overall hunger 1%, regardless of what "bar" you are on. 1% of your overall hunger is 10% of the 'full' bar, and a smaller percentage of the 'hungry' and 'very hungry' bars. I imagine 'starving' is the bottom 50%, but that is just a guess.

Looking at
this chart, we can see that 'wonderful wilderness wurst' has a value of 200. That '200' means 200% of the 'full' bar, and thus 20% of your overall hunger. So, in other words, if you started at 0% overall hunger, you would need to eat 5 wonderful wilderness wursts to reach 100% full.
