I have a few diet ideas.
“Alcohol Diet” when you have cravings drink alcohol (must be hard liquor because it is low-carb).
“DIY Liposuction”, just attach to a shop-vac for those trouble areas.
“Artificial Diet” chlorinate all food products rendering them indigestible.
“Smelly Diet” put something that smells near you when you eat, so that you are too disgusted to eat ... much.
“Coma Diet” induce a coma and let the person starve.
“Nature Diet”, leave dieter in the middle of nature with only water and multivitamins come back in a few months to get them.
“Micro Diet” only eat one ounce meals and they must be separated by an hour.
“Inverted Diet” only eat things hanging upside down.
