usually about a week or two...but you will notice a change in their eating habits first!

[Annie L]

When the face becomes gaunt and hair is starting to fall out. You notice the arms are extremely smaller than usually and the gauntness in the eyes. They become sunken in.

Depends on the person. If they are chubby, then you would see it in about a week. If they were already skinny, then they would look mostly the same because their clothes would hide the bones. Generally, the first place you see it is in the face. They look sick and kind of dead.
