Do expensive juice cleanses really work? Experts say 'there's no way' a liquid detox will remove toxins from your body Juice cleanses are a multi-billion dollar industry crammed with expensive 'detox' bottles of pureed vegetables and fruits. But do they really work? Experts say there is no scientific evidence that the daily juice products remove toxins in the body - a function already carried out by the liver and kidneys. 'There's no way that a three-day detox diet is going to remove toxins that you may or may not have in your body,' Dr David Heber, an endocrinologist at the University of California, told Today. The myth of the juice cleanse? Experts say there is no scientific evidence that daily juice products remove toxins in the body - a function already carried out by the liver and kidneys 'The basic problem is this is an unbalanced diet approach,' he added. While short cleanses may not necessarily be harmful, longer detox can be dangerous - especially for people with medical conditions, pregnant women or the elderly. Dr Roshini Raj, a gastroenterologist at New York University Langone Medical Center, noted that 'some of the cleanses are very extreme and they incorporate only very few ingredients in them. 'So you're really limiting yourself in terms of not getting enough protein, potentially not enough fiber and even healthy fats that you need,' she explained. You're going to eat more later because you're hungrier' And it seems people looking into a juice cleanse for weight loss will only seen fleeting results. 'It's very temporary water weight that you're losing so it's not going to persist,' said Dr Raj. 'You're going to eat more later because you're hungrier. 'It's just not a balanced approach to weight loss, and this notion that you can sort of eat whatever you want and then cleanse for a week and get rid of all the bad effects from the prior poor eating just doesn't make sense.' Instead, she recommends people stick to a balanced diet, and east a lot of vegetables and fruits on a long-term plan. Expensive: A three-day cleanse from Suja will set you back $162; the juice cleanse can actually be dangerous, especially for people with medical conditions, pregnant women or the elderly Too limiting: This Life Juice three-day juice cleanse for $180 may look healthy, but getting a lot of fruits and vegetables 'to the exclusion of everything else' is too limiting and can do more harm than good Losing weight: Doctors explain that people looking into a juice cleanse, such as Abes Market three-day cleanse for $210, for weight loss will only seen fleeting results 'If you find yourself even thinking about a cleanse, it's probably a sign that in general you're not happy with the way you're eating and you might want to talk to someone about a balanced approach,' she said. For the most part, getting a lot of fruits and vegetables 'to the exclusion of everything else' is too limiting and can do more harm than good. 'I don't mind having a juice drink instead of one meal, but when it's three meals for several days, it's not a good idea.'
