    "I'm not a big fan of long term detox or juicing diets," said Pamela Nisevich Bede, co-author of the book "Run to Lose: A Complete Guide to Weight Loss for Runners."

    Detox diets typically involve fasting followed by a strict diet of raw vegetables, fruit, juices, and water.

    Nisevich Bede said there can sometimes be a place for cleansing-type regimens for a day or two if you've overdone it, but people need to be wary of them in general.

    "When we do that day in and day out for weeks, we start to get some nutritional deficiencies," she said, mentioning one recently popular detox trend involving a drink of lemon juice, cayenne pepper, and maple syrup. Stay on a diet like that and you'll miss out on important nutrients including calcium, vitamin D and iron, she said.

    She also recommends avoiding detox diet schemes online that involve buying supplements that promise to "cleanse" your system.

    There's no "crazy magic" product that will get you to a healthy place, Nisevich Bede said. "I'm always wary of any fad diet where you have to buy a certain supplement and have to invest in a pyramid type scheme."

    She said she prefers to recommend a good, old-fashioned diet rich in fruits and vegetables, plus exercise, for people who want to reach a healthy weight.
