Fatness in Fable II
Fable II characters have a number of variables that change depending on your actions during the game. One variable is fatness. Food heals your character when he's injured; but if you feed your character too much food, he'll get fat. Bring his weight down by feeding him celery instead of other foods. Celery subtracts from the fatness score instead of adding to it, so the more your character eats the skinnier he'll get.
Buying Celery in Fable II
You can buy food from shops and market stalls in Fable II. The price will vary depending on where you shop and on the quality of the food. The market in Bowerstone is a good place to buy celery. You can also get celery from the Westcliff food market. If your character is very fat, it may be worth selling any food you are carrying and buying celery instead.
Types of Celery
Celery comes in five star values, from one star Expired celery, which is very unappetizing, to five star Sublime celery, which is lush and delicious. The better quality the celery, the more it will cost. Better quality celery is worth the extra money as it will reduce your fatness more than cheap, poor-quality celery.
Getting More Celery
If your character's fatness score is very high, you may find that you've bought up all the celery in a particular store and still haven't reduced your fatness as much as you would like. Stores and market stalls restock every night, however. To get lots of celery, return to the store every day to buy more.
