Fresh, Frozen, or Canned Fruits ― don’t think just apples or bananas. All fresh, frozen, or canned fruits are great choices. Be sure to try some “exotic” fruits, too. How about a mango? Or a juicy pineapple or kiwi fruit! When your favorite fresh fruits aren’t in season, try a frozen, canned, or dried variety of a fresh fruit you enjoy. One caution about canned fruits is that they may contain added sugars or syrups. Be sure and choose canned varieties of fruit packed in water or in their own juice.
A better approach is to make a few small changes at a time. Keeping your goals modest can help you achieve more in the long term without feeling deprived or overwhelmed by a major diet overhaul. Think of planning a healthy diet as a number of small, manageable steps—like adding a salad to your diet once a day. As your small changes become habit, you can continue to add more healthy choices.
Avoid alcoholic drinks (such as wine, beer, and spirits) during the cleanse. Alcohol is metabolized in the body mainly by the liver. It is broken down briefly to acetaldehyde, a chemical that has the potential to damage liver cells and body tissues, before it is further broken down and eliminated from the body. Besides lightening the load on your liver, avoiding alcohol (and caffeine) for the week can help to shift habits you've cultivated.
Pesticides are toxins, "and I think there's good cause for worry about them," says Purdy. A new study in Food and Chemical Toxicology links pesticide-laced feed to tumors and early death in rats. Organic is ideal, but if that's not possible, pick produce with thick skins that peel off, because they're less likely to be contaminated. (Here's how to save money on organics.)
Purdy recommends DeTox by Yogi and EveryDay Detox by Traditional Medicinals. Both contain dandelion, which supports digestion and liver function; licorice, which expels mucus; and ginger, an antioxidant that stimulates circulation and helps speed toxins out of your system. Tea tip: Steep the tea bags for 10 to 15 minutes, keeping the cup or kettle covered.
Juice diets do prevent your body from going into a state called ketosis, he says. Ketosis means your body has no carbohydrates to burn for energy, so it has to burn stored fat or whatever else is available, he tells WebMD. "You feel bad, even smell bad. That's what makes you feel like hell during a [water-only] fast. But is that because the toxins are coming out? No! You're going into ketosis. It's known physiology."
