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.
Try a lower-calorie version. Use lower-calorie ingredients or prepare food differently. For example, if your macaroni and cheese recipe uses whole milk, butter, and full-fat cheese, try remaking it with non-fat milk, less butter, light cream cheese, fresh spinach and tomatoes. Just remember to not increase your portion size. For more ideas on how to cut back on calories, see Eat More Weigh Less.
It's trendy to think "food should be fuel" or that food is something that helps you lose (or, ahem, gain) weight. But thinking only in terms of number on the scale takes away a huge part of what eating is about: pleasure. "If you think of eating as something enjoyable and something you do without guilt or without judging yourself, and you stay active, you're less likely to overeat, have a better diet, and maintain any weight loss for the long haul," says Zied. It's true: feeling guilty about your food choices can undermine weight loss—and even pack on the pounds—while a celebratory mindset gives you more control over your diet and can thwart weight gain, found a 2014 study in the journal Appetite.
In general, healthy eating ingredients are found around the outer edges of most grocery stores, while the center aisles are filled with processed and packaged foods that aren’t good for you. Shop the perimeter of the store for most of your groceries (fresh fruits and vegetables, fish and poultry, whole grain breads and dairy products), add a few things from the freezer section (frozen fruits and vegetables), and visit the aisles for spices, oils, and whole grains (like rolled oats, brown rice, whole wheat pasta).
Nutritionists are always saying to eat more vegetables, so cook them in a way that takes them from ho-hum to yum. "I even think that steamed veggies can be very boring!" says Ilyse Schapiro, a greater New York City-area registered dietitian. Always incorporate high-flavor add-ons to jazz up veggies, like sautéing with olive oil and garlic, or spraying them with olive oil before throwing them in an oven with salt, pepper, and garlic powder. That way, you don't equate "healthy" with "tasteless," a mindset that will knock you off the veggie bandwagon fast. Another tip: buy a spiralizer and make zucchini noodles. Topped off with a rich tomato sauce, you'll feel like you're eating pasta.
Dinner? That's miso soup with some chopped sea vegetables (like the Japanese nori, used to make sushi) snipped over top. Or you might choose a cup of brown rice with a few chopped vegetables mixed in. "Brown rice gives your body plenty of B vitamins, which is a stress reducer. It's very high fiber, will fill you up, will help you sleep, and will flush you out in the morning."
