Electro Fat is a weight-loss product seen in The Amazing World of Gumball. Supposedly, it works by sending electrical shocks to electrodes placed onto specific areas of the body, stimulating muscles and "melting" fat.
- "The Car": Richard uses it and gets electrocuted. He rips it off, and throws it into Mr Robinson's car. This leaves a dent in the car, causing Richard to attempt to bang it out.
- "The Poltergeist": Gumball uses it to try and cheer up Mr. Robinson. This only hurts him and singes his skin, causing some parts to blacken.
- "The Stars": The name of the product appears as the logo of Richard's computer.
- The Electro Fat slogan is: "Electro Fat! Gets you fit while you watch TV!"
- In "The Car," Electro Fat has a single power setting and is turned on and off with the use of buttons as opposed to the model shown in "The Poltergeist," where power settings are controlled using a dial, though it is possible the on/off button is in the back.
- It is shown to be extremely painful.
