As a nutritionist, I'm always eager to try the latest health trends. For a few years now, friends and clients have been asking about cleanses. "Are they safe?" "Are they healthy?" "Will I lose weight?" So even though I'm a bit of a skeptic, I decided to give one a try. I chose the Cooler Cleanse, created by Salma Hayek and her longtime juice guy, Eric Helms, because it's new and popular. Like many of its competitors (Blueprint, the Love Cleanse), the company offers three- and five-day options, plus a raw food program designed to help you ease in and out of the cleanse, or as a more moderate plan to do on its own. As with other cleanses, you're encouraged to cut out processed foods, alcohol, dairy, sugar, caffeine, wheat, eggs, red meat, sushi, condiments and peanuts for a few days before and after the cleanse.
Most cleanses promise restored energy and cleaner insides. The basic idea behind cleansing is that certain foods tax our system and that cutting out those foods and loading up on fruits and vegetables can help your body run more efficiently and flush out toxins. The theory goes that drinking juice instead of eating solid food gives your digestive system a break because the enzymes and nutrients are broken down (predigested so to speak) during the juicing process. Vitamins, minerals and enzymes are able to reach our internal organs more quickly, where they can help leach out harmful substances. But can flooding your body with fruits and vegetables for three to five days really flush out toxins?
Probably not, say most doctors and nutritionists. The body has a very sophisticated detoxification system at work 24 hours a day. Our livers, kidneys and gastrointestinal tract are designed to eliminate waste material and bacteria. Cutting out certain foods or consuming only juice is not going to help rid the body of irritants and harmful substances or accelerate the detoxification process. Some cleanses encourage colonics or laxatives to aid with elimination. While a short-term cleanse is probably not harmful, these treatments can lead to serious dehydration and other health problems.
As for weight loss, any diet in which you restrict calories or eat less than you burn will help you shed a few pounds, but it probably won't be permanent. That said, it can help kick-start a healthier eating plan. "This is a wonderful way to begin anew, to renew your relationship with food and what you eat and what you put in your body," says Helms. "It's a great tool to spend three days on a cleanse and reassess your relationship with food."
Helms advocates short, functional, easy-to-accomplish cleansing: "This is a nutritional cleanse; it's not about deprivation."
Hayek tells US Weekly that she's being doing juice cleanses for 15 years and has consistently seen positive results.
"I always lose weight," she tells the magazine. "My skin glows when I finish day three. And it inspires me to think about what I put in my body." The actress also balances her cleanses with yoga.
Cooler uses a hydraulic press designed to maximize the nutrient profiles of each juice. Unlike pasteurized bottled juices, the press allows the juice to retain as many vitamins, minerals and nutrients as possible. Nevertheless juice cleanses -- and other programs where you eliminate entire food groups -- are low in many essential nutrients, including protein, fat, iron, calcium and fiber.
While I missed chewing my meals, the juices are tasty and surprisingly satisfying. Some flavors are delicious (I'm now addicted to fresh young coconuts direct from the shell) and others are merely tolerable. Calories range from about 1,100 to 1,200 calories per day. Because I was not looking to lose weight, I supplemented with fresh foods and vegetables throughout the program. This is frowned upon, but I figured as long as I stuck to produce I'd still reap most of the purported benefits. My husband, who did the cleanse with me, did not "cheat" and reports feeling great throughout the three-day period. Some followers complain of headaches or feeling faint, and while I didn't suffer from either of those symptoms (probably due to the fact that I snacked on apples and cucumbers), I did feel less energetic. I did some light exercise (encouraged) on day two and felt good afterward but didn't have tons of energy during the workout. After the cleanse, though, I did feel energized -- more of a psychological than a physiological feeling -- and actually missed my morning juice ritual.
If you're going to cleanse, be sure not to do it for too long or too often. (More than three to five days a few times a year can put you at risk for nutritional deficiencies.) Most adult women need a minimum of 1,200 calories a day, and for men, that number is closer to 1,800. If you dip below that for too long, your body thinks it's starving and reacts by conserving calories, making it more difficult to lose weight. It's also important to keep in mind that any sort of deprivation may send you into overeating mode once the cleanse is over. That's one of the reasons that it is important to transition in and out of a cleanse -- so that you're not reaching for a pint of chocolate fudge brownie the moment you've gulped down your last sip of green juice.
While my general feelings remain unchanged (namely that cleanses are difficult to follow and provide too few calories and other nutrients), it did reinforce some important practical advice that we all know but that bears repeating:
? Portion control. During the cleanse and in the days that followed, I was much more aware of portion size. I realized that when I focused on what I was eating, I could feel full with less food. Which brings me to my next recommendation ...
? Eat mindfully. When I paid attention to my food instead of shoveling it in while talking, typing or staring at the television, I was much more in tune with my hunger and satiety cues.
? Choose wisely. What you are eating is just as important as what you're not eating. Pick whole grains, lean protein, low-fat dairy, healthy fats, and lots of fruits and vegetables.
? Discover new flavors. Instead of relying on salt, sugar and fat while cooking, experiment with different spices, herbs and exotic ingredients.
Bottom line: If you're hoping to drop a couple pounds fast or reevaluate your diet, a cleanse may help. Committing to eating healthier foods in the days leading up to and following the cleanse may even make certain behaviors stick. And we can all benefit from eating more fruits and vegetables. But don't look to it for lasting results or a cleaner system if you return to poor eating habits post-cleanse. With a steep price tag (about $60/day for six servings of juice), a cleanse is unrealistic for most of us. Instead, follow the tips above and aim for at least five servings of fruits and veggies every day.
