In the early 20th century, some individuals ingested tapeworm cysts, believing the parasites would consume excess calories. While weight loss occurred, the diet posed severe health risks, including infections and organ damage.

Also known as the Hollywood Diet, this 1930s trend involved eating grapefruit with every meal, based on the belief that it contained fat-burning enzymes. Despite lacking scientific backing, it remains popular today.

People began eating ice cubes to burn calories through the body heat used for warming up. It sounded scientific, but any weight loss was barely measurable. Still, it became a fad for those hoping for an effortless trick.
