The Flat Belly Diet

The Flat Belly Diet: What It Is

It sounds like a dream come true: Eat certain foods and banish belly fat forever.
The Flat Belly Diet promises a flat belly and weight loss of up to 15 pounds in 32 days. "A flat belly is about food & attitude ... not a single crunch required," it boasts on its cover.

Written in the first person by Liz Vaccariello, editor-in-chief of Prevention, along with Cynthia Sass, MPH, RD, former nutrition director at Prevention, the Flat Belly Diet is targeted to the millions of Americans who want to notch off a few inches or more off their waistline. After all, who doesn't want a trimmer belly?
The basic Flat Belly Diet plan is a 1,600-calorie Mediterranean-style diet with an emphasis on wholesome, unrefined foods including fruits, vegetables, whole grains, nuts, beans, seeds, lean protein, and very little red meat (once a month).
According to the authors, the secret ingredient in the Flat Belly Diet that whittles away belly fat is the addition of a monounsaturated fat, or MUFA, at every meal. MUFAs are found in olives, avocados, nuts, seeds, dark chocolate, soybean, flax, and olive and sunflower oils.
"Research shows that MUFAs have health benefits and target belly fat. They also help control satiety, so by adding in one MUFA at meals and snacks it is easier to stick with the plan and lose belly fat," explains co-author Sass.
Before starting on the 28-day plan, dieters go on a 1,200- to 1400-calorie, four-day anti-bloat jump-start period designed to reduce bloating and get dieters in the mind-set of a healthier eating plan. During the jump-start, dieters drink 2 liters of daily "sassy water," a blend of spices, herbs, citrus, and cucumber. "We tested the diet plan on 11 volunteers and they told us the flavored water reduced bloating, constipation, helped them feel better and get rid of that sluggish feeling," explains Sass.
There's a lot of girlfriend-sounding advice from journalist Vaccariello, who is not a medical professional, along with more credible "notes from our nutritionist" that feature registered dietitian Sass. Success stories of the 11-member test panel are sprinkled throughout the book.
Exercise is optional but encouraged. An entire chapter is devoted to the flat belly workout with diagrams of exercises, walking plans, and a 28-day workout plan.

The Flat Belly Diet: What You Can Eat

Whether you are a vegetarian or a meat eater, have food allergies, or are lactose intolerant, this plan can be adapted to meet your individual needs. The plan calls for four, 400-calorie meals spaced every four hours, and each meal includes a MUFA.
Dieters don't count calories. Instead, they choose from a list of 28 interchangeable mix-and-match breakfasts, lunches, dinners and snack packs. Food lists with portion sizes and calories allow flexibility in creating snack packs and can be used whenever you need it most. Eighty recipes are included with nutrient analysis of calories, protein, carbohydrates, total fat, saturated fat, cholesterol, sodium and fiber.

Sample Anti-Bloat Menu
Breakfast: 1 cup Rice Krispies, 1 cup skim milk, 1/2 cup pineapple, 1/4 cup sunflower seeds
Lunch: 3 oz chunk light tuna in water, 1 cup carrots, 1 light string cheese
Dinner: 3 oz chicken breast, 1 cup mushrooms sauteed in 1 teaspoon olive oil, 1/2 cup brown rice
Snack: pineapple smoothie (1 cup skim milk, 4 oz. pineapple, and 1 tablespoon flaxseed)
2 liters sassy water
Sample Flat Belly Menu
Breakfast: Apple almond oatmeal
Lunch: Pesto ham and cheese sandwich on whole-grain English muffin with lettuce & tomato and 1 cup grape tomatoes
Dinner: 3 oz grilled salmon steak with 2 tablespoons almonds, 1 1/2 cup green beans
Snack: 1/4 cup hummus with 2 tablespoons pine nuts and 1 cup red pepper strips
Calories of meals and snacks during the diet phase are controlled at 400, but the other nutrients can vary. "You can get up to 40% of your calories from fat if you choose the higher fat menu items," says Sass, which exceeds the National Institutes of Health recommendation of 20%-35% of calories.
On the web site, individuals can alter the calorie levels from a low of 1,200 to a high of 2,000 by modifying the snack. Dieters can also send email questions to the authors.

The Flat Belly Diet: How It Works

The premise of the Flat Belly Diet is that if you trim calories to 1,600 per day, add a MUFA at every meal, eat every four hours, and get regular exercise (although this is optional) you will lose weight and belly fat.
For people who skip meals or don't eat breakfast, the structure of the diet can help change bad habits into good ones.
Chances are you will lose belly fat on the Flat Belly Diet, but not because of the MUFAs. When you lose weight, you are more likely to lose it in your midsection regardless of the type of weight loss plan, says Michael Jensen, MD, Mayo Clinic obesity researcher and endocrinology specialist. The plan promotes a lifestyle of overall healthy eating, weight control, stress reduction, and exercise that could be sustained beyond the 32 days.

Beyond the diet book, a series of flat belly cookbooks, a pocket guide, journal, workout, and an online diet option are also available.

The Flat Belly Diet: What the Experts Say

While losing belly fat is important to your health -- extra pounds in your midsection increase your risk of cardiovascular and other diseases more than extra weight in your hips and thighs -- scientific research is scant on diets that specifically target belly fat, Jensen says. And MUFAs are no magic bullet.

"There are so many variables associated with weight loss that it is premature to associate belly fat with a specific food or diet plan," Jensen says.
Christine Rosenbloom, PhD, RD, Georgia State University professor emeritus, also questions some of the advice in the book. "The science behind the jump-start plan associated with stress, gum chewing, bulky raw foods, drinking carbonated drinks, alcohol, coffee, tea, and acidic fruit juices is pure speculation and not based on scientific research," she says. "There is not adequate scientific evidence to link lack of sleep, stress, or MUFAs to a reduction in belly fat."
She likes the addition of the healthy fats because they make dieting easier and deliver important nutrients like fat-soluble vitamins. But she cautions dieters to watch the portions of high-calorie fats. "Monitor your portions because it is so easy to overeat things like nuts and guacamole and if you are not careful, they will cause weight gain instead of helping you lose weight," she warns.
Losing 15 pounds in 32 days is most likely the result of losing water weight, not the fat loss that dieters seek. "A pound of fat equals 3,500 calories, so to lose 15 pounds in 32 days of real fat, you would need to burn off 1,640 calories each day and that is not likely," she says. Losing weight quickly can be a real motivator as long as dieters recognize that real fat loss is slower and more likely to be at the recommended safe rate of 1-2 pounds per week. Additionally, Rosenbloom notes, research does not support the notion of spot reduction for losing belly fat.
Rosenbloom says, "To keep your belly in check, remember the acronym SED: Strength training to preserve muscle mass, Exercise aerobically to burn fat, and your Diet should be healthy, calorie-controlled, and include heart-healthy fats."

You can lose weight on The Flat Belly Diet plan, but don't be fooled into thinking MUFAs have magic belly-flattening nutrients capable of melting away belly fat.
It is a calorie-controlled, Mediterranean-style diet plan that can help you lose weight in a safe and effective manner. The Mediterranean diet has been proven to be a nutritious and healthy plant-based plan that is good for your heart and overall health.
What will melt body fat, including belly fat, is losing weight on a well-balanced plan like this one or any other healthy, calorie-controlled eating plan.
