LOS ANGELES (KABC) --About 20 percent of adults concerned about their weight have tried a juice cleanse, and surprisingly men are edging out women. Juice cleanses are an estimated $200 million per year industry.
Susan Williams did her first juice cleanse two years ago and has done several since.
"I will do a cleanse if I've eaten too much, if I've been drinking too much, if I've been having too much sugar. I feel like it resets my system," Williams said.
By replacing solid foods with juices made from fruits, vegetables and even nut milks, some cleanses claim to jumpstart a healthier you.
Consumer Reports' nutritionist Amy Keating looked at three-day programs from some top-selling brands, including BluePrint's Renovation Cleanse, Pressed Juicery's Cleanse One and Suja's Original Fresh Start.
They promise to do things like "rest your digestive system, "rejuvenate your body," "increase energy" and "eliminate toxins."
"We just didn't see a lot of evidence to back some of the claims they make," Keating said.
None promise you'll drop pounds, but you probably will in the short term because most are relatively low in calories.
The juices Consumer Reports reviewed also tended to be low in fiber and protein and too high in sugars, and they're pricey. Three days of juices can cost as much as $200.
As with any diet, Consumer Reports advises checking with your doctor first if you want to do a cleanse. Consumer Reports reached out to the manufacturers regarding the claims they make. Some did not respond but those that did respond defended the benefits of their products.
After reviewing the information and conducting their own research, Consumer Reports' health experts remain unconvinced the products are worth the money.
