Do-It-Yourself Diet

Do-It-Yourself Diet
By Sally Kuzemchak, RD, Prevention

Every season brings a new crop of diet books to store shelves. That's not surprising, because more than 60% of Americans say they want to lose weight. But what is surprising: Most of us don't stick to these printed plans, according to recent market research. In fact, the most popular—and successful—diet today is the one we make up ourselves.

"The key is to take a few proven weight loss tricks and personalize them," says Lisa Young, PhD, a professor of nutrition at New York University. So rather than adapting your life to fit a set of rules, you adapt the rules to fit your life. Here, we look at popular strategies backed by solid research and offer smart, practical ways to make them work for you.

What Works: Cut Carbohydrates

It's simple math, really: The average American eats about twice the recommended daily servings of grains (many in the form of refined flour products such as white bread, pasta, and sweets), plus about 20 teaspoons of sugar (mostly from sweetened drinks). Eliminating those nutrient-wimpy simple carbs cuts a big source of empty calories; skipping even just one 20-ounce cola every day saves you 17 teaspoons of sugar, 250 calories—and about 26 pounds over the course of a year!

Do It Your Way

Your body needs carbohydrates for energy; what you should do is eat smaller amounts of healthier ones, says Kathy McManus, RD, director of nutrition at Brigham and Women's Hospital in Boston. Here's how:

Choose whole grains

They're an important source of nutrients and help keep your blood sugar steady between meals and your appetite in check.

Have just one with every meal and snack

That'll get you the appropriate five or six servings a day. To control portions, picture your plate as a clock and limit your carbs to the space between noon and 3 pm.

Balance the bad carbs

If you do eat refined foods, like white bread, pair them with a food that has protein or healthy fat, like hummus. That will help nix a blood sugar spike-and-crash, says Cathy Nonas, RD, director of the Diabetes and Obesity Programs at North General Hospital in New York City.

What Works: Eat High-Volume Foods

When you're hungry, you want to eat. Choose foods high in water and fiber and low in calories (think salad and broth-based soup), and you can eat a lot, feel full, and lose weight. Consuming supersize portions activates stretch receptors in your stomach, which then fire off "full" signals to your brain - but you've filled up and stretched without overdoing it on calories.

Do It Your Way

Add heft to every meal by reducing your portion of low-volume foods and folding in high-volume (but low-cal) ones. Fruits and vegetables, which are 80 to 95% water, are good additions, as are air-filled foods, such as puffed cereal instead of flat flakes. More simple swaps to fill your belly faster with more nutrients but far fewer calories:

Low volume: Cheese and crackers
High volume: 6 cups of popcorn sprinkled with Parmesan cheese

Low volume: Dried fruit and nut mix
High volume: Fresh fruit, like strawberries or grapes, and 1/4 cup of nuts

Low volume: Rice
High volume: Half your usual amount cooked with a box of frozen veggies

What Works: Boost Protein

Protein can take about 4 hours to digest, while carbs take only 2; slower digestion means you feel fuller longer. Plus, protein may help jack up your metabolism: In a new study from Purdue University, dieters who ate 30% of their calories from protein preserved more lean body mass while losing weight than those who ate only 18%. The more lean body mass you hold on to, the more calories you burn at rest.

Do It Your Way

Forget the cheese and bacon of diets past; instead, add a little protein to every meal and snack, says McManus.

Choose healthy sources
That means proteins with unsaturated fats (like salmon and soy), not the cholesterol-boosting saturated kind (packed into fatty cuts of beef and whole dairy products).

Stick to proper serving sizes

Three ounces of lean meat looks like a deck of cards, the same amount of fish is the size of a checkbook, and your thumb marks an ounce of cheese.

Add protein to your favorites

Combine ground turkey or shrimp with spaghetti and sauce; stir 1 ounce of walnuts into oatmeal; spread a little almond butter on toast before the jam.

What Works: Replace Meals with Bars and Shakes

These products make portion control a snap. "It's calorie cutting without a calculator," says Nonas. An analysis of studies from Columbia University found that women who had one to two liquid meal replacements daily lost an extra 2 pounds per month compared with other dieters who had the same calories.

Do It Your Way

Think of a bar or shake as your go-to food when you're in a pinch. Whether you use them as a meal or as a snack, look for at least 3 g of fiber, 10 g of protein, and 3 g or less saturated fat, and follow these healthy eating guidelines:

As a meal:

Most bars and shakes have about 220 calories, so pair either with a small salad with low-fat dressing or a piece of fruit to help fill you up.

As a snack:

Between meals, 220 calories is too much. If you have a bar late in the afternoon, for example, cut dinner by half to keep your calorie counts in check.

What Works: Keep a Food Diary

Journaling helps expose bad habits that may otherwise fly under the radar, so you can change them. "When you write down what you eat, you eat less," says Anne Fletcher, RD, author of Thin for Life. A study from Kaiser Permanente Center for Health Research showed that keeping a food diary was a better predictor of weight loss than even exercise!

Do It Your Way

Beat journal boredom—and the guilt that comes with committing that cookie to paper—by planning your ideal eating day: Essentially, keep a "reverse" diet diary where you map out your menu ahead of time and try to stick to it. Track your victories, too: Buy gold star stickers and put one in your planner for every serving of veggies. "The positive reinforcement builds confidence and motivation, and that's key to success," says McManus.

Outsmart These Diet Traps

Our best eating-plan pairings for 5 of the most common rough spots

Fancy dinner out
The formula: Boost Protein + Volumize

Have a high-protein snack midafternoon (such as almonds and fresh fruit) to take the edge off your hunger. Then order a bowl of broth-based soup or a green salad before the meal.

Overscheduled day
The formula: Journal + Use Meal Replacements

The night before, try to plan out your day with a reverse food journal. Toss a bar or shake and an apple in your bag in case plans change or you're starving with no time to buy lunch.

The 4 PM munchies
The formula: Cut Carbs, Volumize + Boost protein

Skip hunger-stimulating refined carbs like sweets and white bread in favor of only whole grains, such as whole wheat crackers (pick those that contain at least 3 g of fiber per serving). Bulk up your lunch with extra vegetables, like grape tomatoes, baby carrots, or red bell pepper strips, and be sure to have a few ounces of protein, such as thin slices of lean ham on whole grain bread or a chopped egg and a handful of sunflower seeds on a salad.

A party buffet
The formula: Boost Protein + Volumize

Fill at least three-quarters of your plate with low-calorie buffet standbys that are rich in fiber, water, or (low-fat) protein, such as shrimp cocktail, vegetables, lean meats, and fruits.

Late-night cravings
The formula: Journal + Volumize

Jot down what you eat on every trip to the kitchen. If you must munch while watching TV, choose low-cal foods you can eat more of, like air-popped popcorn or a plate of cut up veggies.
