I wouldn't wear that weighted vest too much. If you wear it all day, it will have the same adverse effect on your joints as being 20 lbs overweight.

It's fine to use it to add work to body-weight exercises such as pullups, squats, etc. but don't wear it for hours just walking around.

Surely that’s only true if the poster is already at the high end of normal? If he weighs 160lbs adding 20lbs isn’t going to do any harm.

The issue with things like weighted vests or weighted leg braces is that it's 20 lbs in one place, and it's not attached to you the same way your flesh is. If you gained 20 pounds it'd be distributed around your body, on various joints. No single place would experience significantly more stress. If you put on a vest, all that weight is being placed on your shoulders, which isn't somewhere you normally have much weight.
