For years the Cabbage Soup Diet was the go-to for women who wanted to lose weight fast - but there's nothing fun or sexy about chowing down on cabbage for days on end.
Yes, it's cheap, but experts believe you are simply losing water weight, depriving your body of protein and opening yourself up to uncontrollable cravings. The bottom line? It's better in theory than it is in practise.
But can a new wave of soup diets banish this bad karma and make us all fall in love with liquid diets all over again?
Well, according to Fiona Kirk, best-selling author of So What The F**k Should I Eat?, Eat Live & Lose The Flab, and now Soup Can Make You Thin, slim people know that a tasty bowl can fill you up, crush cravings and keep you energised.
Plus, she believes a soup-only diet can help you lose weight in as little as 10 days.
Her trick is to eat a variety of different soups that include vegetables, beans, healthy fats like olive oil and protein, for breakfast, as a snack and before bed to encourage a good nights sleep.
So is this overkill or accurate? Soup diets claim to work because of the combination of water and nutrient-rich vegetables, which results in goodness being more readily absorbed into the body (and drastically reduces bloating). In reality, soup diets work in the same way as any extreme calorie restriction regime.
At the same time the lack of calories flushes liquids from your system, which means that 3lbs loss you see in three days could just be from water.
What's the verdict?
If you want to lose weight fast for a big event or party then this will defo do the trick, but the weight you lose won't be maintainable once you revert back to solid food.
It is not designed to be a long term solution, so never stay on a soup diet for more than seven days. Listen to your body - if you start getting headaches or feel light-headed you might not be getting enough calories.
Can I do a slightly less drastic version?
YES! Swapping your cheese filled sandwiches for a hearty vegetable soup and a bread roll at lunchtime will help towards a healthy weight loss programme. Plus, the fibre from the vegetables should keep you feeling fuller for longer so you're less tempted by the choccie biscuts.
