No, “short-weighted” doesn’t have to do with your latest diet. It’s when a manufacturer sells less of a product than is advertised on the package. Consumer Reports magazine states that this problem occurs in everything from area rugs to yogurt.

In some cases, the shortage occurs due to an oversight by the manufacturer, such as when a product loses moisture due to a packing problem. In others, it can be a deliberate action on the part of the maker.

When that 20-ounce bottle of ketchup fails to produce 2 cups what should you do? The first step should be a complaint to the manufacturer. If you suspect this is a common practice rather than a one-time occurrence, contact weights and measures officials, often in the local agriculture department. Also, register your complaint with Call For Action.
