Now is your chance to hit the reset button and go healthy. One way to do that is to try a fast. “You can lose at least a pound a day, get rid of foggy brain and recharge your energy,” said best-selling author and nutritionist Cherie Calbom, known as “The Juice Lady” for her expertise in juicing for health and detoxification.

“Fasting is a great way to restart your metabolism, purify your lymphatic system and revive your soul,” said Calbom, author of the new book, The Juice Lady’s Guide to Fasting. “It’s also a way to look younger, clear out the toxins and restart the systems in your body for optimal health and physical well-being and to bring restoration to your mind, body and spirit.”

People often think of fasting as a fad, she said, but it’s been touted throughout history – by the healer Hippocrates, the philosopher Plato and scientist and statesman Benjamin Franklin, just to name a few. Germany’s famous “fasting therapist,” Otto Buchinger Sr., MD, called it an “operation without surgery.”

Even those who don’t believe in fasting’s curative powers agree it can help prevent illness. Want to fend off the flu, a cold or bronchitis? Fasting gives your immune system a boost.

“It’s a lot like a threefold spring cleaning, as you dive deep into the areas in your life that don’t always get the attention they need – mentally, physically and spiritually – and you clean them up,” Calbom said. “You rid yourself of toxic influences that hinder growth, clarity and well-being and refocus on the future.”

With a liquid fast, you give up solid foods and enjoy delicious, nutrient-rich beverages. In her book, Calbom provides a variety of fasts to choose from, including a smoothie fast, bone-broth fast, three-day detox fast, and what she says is the most popular of all – the juice fast. If you crave crunch, she offers the Garden of Eden Fast and the Daniel Fast.

“There’s something for everyone – from a short, weekend weight-loss fast to a 21-day rejuvenation fast,” she said.

Calbom recommends writing down what you hope to achieve with your fast – losing belly fat, cleansing your liver or boosting your brain power – with detox juices, for example – in order to find a fast that’s a good fit.

If you aren’t sure you can hack a liquid fast because you’ll crave flavor, think again. Here are three of Calbom’s favorite recipes, designed to taste great while doing good.

Cherie Calbom holds a Master of Science degree in whole foods nutrition from Bastyr University. Known as “The Juice Lady” for her work with juicing and health, she is author of 31 books, with millions of copies sold worldwide.
