What is *Mindless Eating* by Brian Wansink about?

*Mindless Eating* explores how hidden environmental, social, and psychological factors—like plate size, food packaging, and dining ambiance—subconsciously influence our eating habits. Brian Wansink reveals how marketers, restaurants, and even home kitchens manipulate consumption patterns, offering strategies to make healthier choices without drastic dieting.

Who is Brian Wansink?

Brian Wansink is a consumer behavior expert and former director of Cornell University’s Food and Brand Lab. With a PhD from Stanford, he authored over 200 studies on eating psychology and advised the USDA on dietary guidelines. His work focuses on how subtle cues shape food decisions.

Who should read *Mindless Eating*?

This book suits anyone seeking to understand unconscious eating triggers, from dieters to marketers. It’s valuable for parents, health professionals, and individuals aiming to redesign their food environment for better habits without willpower struggles.

Is *Mindless Eating* worth reading?

Yes—it blends accessible research with actionable tips, like using smaller plates or hiding snacks. Wansink’s insights help readers identify hidden eating traps and make incremental changes for long-term health, avoiding fad diets.

What is the “mindless margin” concept?

The “mindless margin” refers to the 100-200 daily calories people unknowingly overeat due to environmental cues. Small changes, like reducing portion sizes by 20%, can reverse weight gain without feeling restrictive, leveraging this psychological buffer.

How do environmental factors influence eating habits?

Dining ambiance, music, lighting, and even container transparency impact consumption. For example, people eat 28% more from large bowls or when distracted by TV. Wansink suggests rearranging kitchens to prioritize healthier foods.

What strategies does *Mindless Eating* recommend for mindful habits?

Key tactics include: - Pre-plating meals to avoid second servings. - Using tall, slender glasses to reduce liquid intake. - Keeping unhealthy snacks out of sight. - Eating slowly to recognize fullness signals.

How does food presentation affect consumption?

Studies show people consume 22% more when food is served family-style and 31% more if containers are transparent. Wansink advises using smaller plates and arranging vegetables prominently to nudge healthier choices.

Chapter 1

The Invisible Forces That Shape Our Eating Habits

Every day, you make over 200 food decisions without realizing it. Yet these unconscious choices aren't primarily driven by hunger-they're shaped by environmental cues from family, friends, packaging, plates, names, numbers, labels, lights, colors, shapes, and countless other invisible influences. This groundbreaking insight forms the foundation of "Mindless Eating," the New York Times bestseller that revolutionized how we think about food psychology. Author Brian Wansink, former director of the Cornell Food and Brand Lab and USDA nutrition executive, has conducted over 250 studies examining how unconscious factors shape our eating habits. His work has been featured everywhere from academic journals to The Today Show and has influenced food policy at the highest levels. Even Oprah Winfrey cited his research when explaining her own weight management strategies. What makes this book particularly powerful is its rejection of deprivation-based dieting in favor of subtle environmental changes that help us eat less without realizing it-creating what Wansink calls "the best diet is the one you don't know you're on."

Chapter 2

The Mindless Margin: Small Changes, Big Results

Why do we eat stale popcorn at the movies? Why do we finish everything on our plate even when we're full? The answer lies in what Wansink calls the "mindless margin"-the zone where we can slightly overeat or undereat without noticing. In a now-famous experiment at a Chicago movie theater, moviegoers were given either medium or large buckets of deliberately stale, five-day-old popcorn. Despite the terrible taste-one person compared it to "Styrofoam packing peanuts"-people with larger buckets ate 53% more (173 calories) than those with medium buckets. When asked afterward if bucket size influenced their consumption, most smugly denied it. The container size, not hunger or taste, determined how much they ate. This pattern repeats across countless scenarios. At the Spice Box restaurant, diners received identical $2 Charles Shaw wine with different labels. Those who thought they were drinking California wine ate 11% more food, lingered 10 minutes longer, and rated the entire meal more positively than those who believed they were drinking North Dakota wine. The wine itself was identical-only the expectations changed. Most diets fail because they're deprivation-based, and they fail for three critical reasons: our bodies fight against them by slowing metabolism; our brains fight against them through increased cravings; and our environment constantly tempts us with readily available, highly appealing options. Over 95% of dieters regain lost weight because willpower alone isn't enough to make 200 daily food decisions correctly. The good news is that the mindless margin works in reverse. While we'd notice eating 1,000 calories too few (feeling weak, cranky) or 1,000 too many (feeling sluggish, heavy), the difference between 1,900 and 2,100 calories daily is imperceptible. Yet this small 100-200 calorie difference-just one stick of gum or three jelly beans daily-can lead to gaining or losing 10-20 pounds over a year. The key strategy: Think 20% less. While Americans typically eat until they're full, people in leaner cultures like Okinawa practice hara hachi bu-eating until they're 80% full. Simply dish out 20% less food than you think you might want before you start eating. Research shows people can eat 20% less without noticing (though they do notice at 30% less). Simultaneously, increase fruits and vegetables by 20% to maintain volume while reducing calories.

The Forgotten Food: We Eat With Our Eyes, Not Our Stomachs

Our stomachs are terrible at counting. They can't track spoonfuls of cereal, ounces in drinks, or French fries consumed. Our attention and memory offer little help-studies show 31% of people leaving Italian restaurants couldn't remember how much bread they ate, and 12% denied eating any bread at all. A Midwestern sheriff noticed inmates mysteriously gained 20-25 "prison pounds" during their average six-month sentences. The culprit wasn't the food quality or lack of exercise-it was their baggy orange jumpsuits. The loose-fitting uniforms provided no feedback about their gradual weight gain of about a pound per week. Most people rely on "signal clothes"-favorite jeans or belt notches-rather than scales to monitor their weight. Rather than internal fullness cues, we rely primarily on visual volume to determine when we've had enough. Dr. Barbara Rolls' research shows that people feel equally satisfied with smaller portions when they appear the same size. A quarter-pound hamburger bulked up with lettuce, tomato, and onion can be as satisfying as a half-pound burger despite fewer calories. In experiments with strawberry smoothies, adding air through blending created larger-looking drinks that led students to eat 12% less lunch, despite identical calorie content. Contrary to popular belief, we don't stop eating because our stomachs are full. Instead, we decide how much to eat before we start, dish it out, and eat until it's gone-like a jogger who decides to run to the school and back rather than constantly asking "Am I tired yet?" Most Americans finish meals in less than 20 minutes-far less than the time it takes our bodies to signal fullness. In the "bottomless soup bowl" experiment, researchers created bowls that secretly refilled through hidden tubes. People with normal bowls ate about 9 ounces of soup, while those with the bottomless bowls consumed an average of 15 ounces-73% more-without realizing it. Despite consuming significantly more calories (268 versus 155), the bottomless bowl diners estimated they'd eaten about the same amount as those with regular bowls. Most people are terrible at estimating calorie consumption. Normal-weight individuals typically underestimate by 20%, while obese people underestimate by 30-40%. Research by Wansink and Pierre Chandon revealed that meal size, not body size, determines estimation accuracy. Everyone-regardless of weight-becomes increasingly inaccurate when estimating larger portions. The solution? See all you eat. Pre-plate everything-you'll eat about 14% less than taking multiple servings. And keep evidence of consumption visible-like chicken bones or empty beverage containers-to remind you how much you've already had.

Chapter 4

Surveying the Tablescape: How Dishes and Packages Trick Us

The seemingly innocent tablescape of our meals-packages, dishes, glasses, and food variety-can mindlessly increase how much we eat by over 20%. These hidden persuaders in our kitchens can work against us, or be harnessed to decrease our consumption. Our oversized American kitchens encourage us to buy bigger packages, which leads us to make bigger meals and eat more food. In dozens of studies with different foods, people given large packages consistently prepare and consume 20-25% more than those with medium packages. With snack foods like M&Ms, the difference is even more dramatic-people given one-pound bags ate nearly twice as many as those with half-pound bags. Our brains fall prey to the Horizontal-Vertical illusion-overestimating height while underestimating width. In studies with health camp teenagers, jazz musicians, and even professional bartenders with years of experience, people consistently pour 19-74% more liquid into short, wide glasses than tall, skinny ones of identical capacity. Even when told to be careful, experienced bartenders still poured 37% more alcohol into short tumblers than tall highball glasses. The Size-Contrast illusion makes food portions look smaller on large plates than on small ones, leading us to serve ourselves more. Even nutrition professors and PhD students at an ice cream social dished out 31% more ice cream when given 34-ounce bowls instead of 17-ounce bowls. With larger scoops too, they served 57% more. Even intelligent, educated people fall prey to serving-size biases. When Wansink tested 63 graduate students who had received extensive training on size bias, they still served themselves 53% more Chex Mix from gallon bowls than from half-gallon bowls at a Super Bowl party six weeks later. Not only did they take more, they ate 59% more too. Variety drives us to eat more due to "sensory specific satiety"-our senses get numbed with repeated exposure to the same stimulus. Even perceived variety matters: MBA students given jelly beans in six organized compartments took only 12 candies, while those given the same beans mixed together took 23. Similarly, people eat 43 more M&Ms when presented with 10 colors versus 7 colors, despite identical taste. To combat these effects, mini-size your boxes and bowls-the bigger the package you pour from, the 20-30% more you'll eat. Repackage jumbo boxes into smaller containers and serve in smaller dishes. Use mid-size plates instead of platter-size ones-six ounces looks substantial on an 8-inch plate but tiny on a 12-inch one. Choose slender glasses to pour less liquid. Finally, beware the double danger of leftovers: multiple side dishes encourage more eating, and they signal that you made and likely ate too much of the original meal.

Chapter 5

The Hidden Persuaders Around Us

Most people are on "see-food" diets-they eat what they see. When we see tempting food, our bodies physically prepare for eating by releasing insulin, which lowers blood sugar and increases appetite. The more we salivate over food, the more impulsively we eat it. Simply thinking about food makes us hungry. In one study, people who wrote detailed descriptions about their last soup-eating experience anticipated eating twice as much soup in the coming month. The solution is simple: make tempting foods invisible and healthy foods visible. The more hassle it is to eat, the less we eat-a principle demonstrated in both rats and humans. In Wansink's candy dish study with secretaries, they ate nine chocolates daily when the dish sat on their desk, six when it was in a desk drawer, and only four when placed six feet away. That six-foot distance created crucial thinking time between impulse and action. Even minor barriers matter-in cafeterias, 30% of diners took ice cream when freezer lids were open, but only 14% did when they had to lift the lid. Soldiers drank 81% more water when pitchers were on dining tables versus side tables. Convenience shapes our preferences so powerfully that we learn to prefer mediocre microwave popcorn over tastier but less convenient stovetop varieties. Warehouse clubs create two consumption traps. First, after paying membership fees, we frantically "recoup" our investment by overbuying. Second, bulk purchases affect how much we eat. Studies with warehouse club members showed they consumed free stockpiled foods at nearly double their normal rate during the first week before consumption tapered off. While warehouse clubs save money at checkout, we lose those savings if we overbuy, eat food we no longer enjoy just to "finish it," or gain weight from mindless consumption. Creating small barriers between you and tempting food can dramatically reduce consumption. When Wansink moved candy dishes six feet from secretaries' desks, they ate half as many candies because that small distance created a "pause point" to reconsider their hunger. Apply this principle by leaving serving dishes in the kitchen instead of on the table, de-conveniencing tempting foods by storing them in hard-to-reach places, and establishing a rule to snack only at the table on a clean plate.

Chapter 6

Mindless Eating Scripts: The Power of Patterns

We develop automatic eating patterns-scripts-that guide our consumption without conscious thought. These scripts dictate when we eat, how much we eat, and when we stop. Many people stop eating not because they're full, but because they've finished reading, their TV show ended, or their companions finished eating. Social eating dramatically increases consumption. When eating with one other person, we eat about 35% more than alone; with seven or more people, we eat nearly double (96% more). This happens because we lose track of our intake during conversation, extend meal duration to maintain company, and mimic others' eating pace. We tend to follow the group norm-light eaters eat more in groups while heavy eaters eat less. Gender creates opposite eating scripts during dating. Women who pay attention to their eating consume less, believing smaller appetites appear more feminine. Men who monitor their eating actually eat more, viewing voracious appetites as "studly" and "powerful." Research showed men who read about a character eating "almost all his popcorn" rated him stronger and more masculine than those who read he ate just "a couple handfuls"-even estimating he could bench-press 21 more pounds. Ironically, when women evaluated the same scenarios, they weren't impressed by the hearty eater. Television viewing correlates strongly with weight gain across all demographics. TV creates a triple threat: it prompts eating, prevents awareness of consumption amounts, and extends eating duration. Research showed people watching a one-hour TV program ate 28% more popcorn than those watching for just 30 minutes. All distractions-including reading newspapers or books-increase consumption by taking focus away from food. Even radio listening increases intake by 15%. Restaurant atmosphere significantly impacts how much we eat through two mechanisms: eating duration and eating speed. Soft lighting and music in upscale restaurants make us linger longer, increasing our likelihood of ordering unplanned desserts or extra drinks. One study found diners in restaurants with slow, pleasant music stayed 11 minutes longer and spent 41% more on drinks than those in restaurants with fast music. Smell powerfully influences our eating behavior, directly connected to taste perception and memory. The "Cinnabon Effect" demonstrates how strategically placed food aromas can trigger cravings and drive sales ($200 million in 2003). Research with the U.S. Army tested how scent affects consumption by serving oatmeal in bowls with different embedded aromas. People ate significantly more when their plain oatmeal was served in cinnamon-raisin scented bowls, but less when served in macaroni-cheese scented bowls. Weather and seasons profoundly affect our eating patterns. In cold weather, our bodies require more energy to maintain core temperature, increasing hunger and speeding digestion. Conversely, in hot weather, we prioritize liquids for cooling and naturally eat less. Companies like Campbell's Soup strategically exploit weather-eating connections with "storm spots"-radio ads targeting households during rainy, chilly days when soup appeals as comfort food.

Chapter 7

The Name Game: Taste What You Expect to Taste

Our taste buds are as influenced by our minds as by our mouths-we often taste what we expect to taste. This "expectation assimilation" affects everyone from high-end chefs to home cooks, making presentation and naming crucial to how we perceive flavor. At the U.S. Army Natick Soldier Center, researchers asked 32 participants to taste "strawberry yogurt" in complete darkness-but actually gave them chocolate yogurt. Remarkably, 19 of them rated it as having good strawberry flavor, with one even claiming it would be her new favorite brand. This demonstrates how powerfully suggestion can override our actual taste experience, especially when visual cues are absent. A World War II Navy cook named Billy discovered the power of visual cues when he ran out of cherry Jell-O during a long tour. Facing complaints from sailors, he simply added red food coloring to lemon Jell-O. Not only did no one notice, some sailors actually complimented him on finally finding cherry Jell-O. Restaurant owners know that descriptive, evocative menu language dramatically influences both sales and perceived taste. In a six-week cafeteria experiment, identical foods were given either basic names (like "Red Beans and Rice") or descriptive names (like "Traditional Cajun Red Beans with Rice"). The descriptively named foods sold 27% more, were rated as better values despite identical pricing, and were perceived as tastier. Even more remarkably, diners who ate the descriptively named foods developed more positive attitudes toward the entire cafeteria. Brand names create powerful taste expectations that transform our actual experience. In central Pennsylvania, a drink called "It Cola" costs less than half the price of Coca-Cola yet tastes nearly identical in blind tests. However, most consumers willingly pay the premium for the "Real Thing" because the brand creates positive expectations. Studies consistently show that most self-proclaimed "brand loyal" consumers cannot identify their preferred brands in blind taste tests once labels are removed. Names transform our perception of food so dramatically that even identical wedding menus seem worlds apart when one lists "Beef" while another offers "Slow-roasted, tender Prime Rib." During WWII, when meat shortages threatened America's protein supply, the government recruited anthropologists and psychologists to rebrand unappetizing "organ meats" as more appealing "variety meats" to increase consumption. We taste what we expect to taste, which is great news for amateur cooks. Simply using descriptive, positive language when announcing dinner transforms the dining experience-words like "traditional," "succulent," or "homemade" make food taste better and elevate perceptions of the cook's skill. The final 15 minutes of meal preparation are best spent not on the food itself but on creating the right atmosphere: soft lighting, nice plates, pleasant music, and attractive presentation.

Chapter 8

In the Mood for Comfort Food

Comfort foods are widely misunderstood, as evidenced by three common myths found in popular magazines: that most comfort foods are unhealthy indulgences, that people eat them when sad or stressed, and that comfort food preferences become fixed in childhood. Contrary to popular belief, 40% of favorite comfort foods are actually fairly healthy-pasta, meats, soups, and casseroles. Men and women differ dramatically in their preferences: women favor ice cream, chocolate and cookies (all sweet snacks), while men prefer ice cream, soup, and pizza/pasta (mostly hot meal foods). This gender difference stems from associations-men feel "pampered" by these foods, while women associate them with preparation work. Most surprisingly, people are twice as likely to reach for comfort foods when happy (86%) than when sad (39%), though mood does influence what we choose-happy people prefer healthier foods like pizza or steak, while sad people reach for ice cream, cookies, or chips. Comfort food connections form subconsciously. Through "laddering" interviews that map associations, researchers found two main reasons foods become comforting: past associations with specific people or events, and personality identification. For example, one woman's popcorn-M&Ms mixture reminded her of college days with her husband, creating feelings of safety and coziness. Some people are drawn to foods that match their self-perception-someone "sweet and petite" identifies with angel food cake, while someone "warm and nurturing" identifies with soup. American eating habits transformed dramatically over the past 75 years, with ethnic cuisines becoming mainstream. World War II veterans returning from Europe readily embraced familiar-seeming French, Italian and German foods. However, Pacific veterans had more polarized reactions to Chinese food-either loving or hating it even 50 years later. A survey of 261 South Pacific veterans revealed the determining factor: those who experienced heavy combat (31%) developed lasting negative associations with Asian cuisines, while non-combat personnel like mechanics and clerks (46%) maintained positive associations. People fall into two distinct eating patterns: saving their favorite foods for last or eating them first. Research with 183 participants revealed this division stems from childhood family dynamics. Those who grew up as only children or firstborns typically save their favorites, confident the food will still be there. Conversely, those from large families or who were younger siblings tend to eat their favorites first, having learned through competition that desirable foods might disappear.

Chapter 9

Nutritional Gatekeepers: Shaping Family Food Habits

Most people believe they control their own food choices, but many are actually habits inherited or conditioned by our parents. Now as adults, we have the opportunity to influence the next generation as "nutritional gatekeepers"-the people who do most of the food shopping and meal preparation in households. Nutritional gatekeepers control a remarkable 72% of their family's food decisions, according to experts and over 2,500 parents surveyed. Those who rated themselves as "good cooks" reported even higher influence. Research identified five distinct types of good home cooks: Giving Cooks (22%) who specialize in comfort foods and traditional favorites; Healthy Cooks (20%) who experiment with fresh ingredients; Innovative Cooks (19%) who create without recipes; Methodical Cooks (18%) who follow recipes precisely; and Competitive Cooks (13%) who cook to impress. All types except Giving Cooks helped their families eat healthier, primarily through introducing food variety. Children develop food preferences before birth, with studies showing babies whose mothers drank carrot juice during pregnancy preferred carrot-flavored cereal months later. By four months old, infants pick up on subtle caregiver cues about foods. Research from the Massachusetts Reformatory for Women in the 1940s revealed babies abruptly changed juice preferences when caretakers changed, mirroring the new caretakers' preferences. Even two-day-old babies can imitate facial expressions, suggesting grimaces or smiles toward foods powerfully influence children's tastes. Just as Pavlov conditioned dogs to salivate at a bell, children can be conditioned to associate eating with specific cues. Psychologist Leann Birch demonstrated this by conditioning preschoolers to eat when exposed to particular lights and music, even after they'd just eaten lunch. The Wansink Lab's "Popeye Project" found parents successfully created positive associations with healthy foods through strategic messaging: "spinach makes you strong like Popeye," "fish makes you smart," or "carrots help you see far." A critical transformation in eating habits occurs between ages three and five. Three-year-olds naturally stop eating when full, regardless of portion size. By age five, however, children eat whatever they're given-if served large portions, they'll consume more and even take larger bites. This was demonstrated by Leann Birch and Jennifer Fisher's research showing five-year-olds ate 26% more macaroni and cheese when given larger servings, while three-year-olds ate the same amount regardless of serving size. As the nutritional gatekeeper controlling 72% of what your family eats, you can create positive lifetime food patterns by: being a good marketer (presenting healthy foods as fresh and energizing rather than punishment); offering variety to develop well-rounded eaters; implementing the Half-Plate Rule (half the plate should contain vegetables and fruits, with protein and starch on the other half); and making serving sizes official through sealed containers that prevent children from seeing extra snacks which could distort their perception of appropriate portion sizes.

Chapter 10

Fast-Food Fever: Why We Fall for Health Halos

Fast food conquers the world by appealing to our genetic predisposition for fat, salt, and sugar-tastes that helped our ancestors survive. These foods offer what hunter-gatherers would kill for: french fries deliver salt and fat, donuts provide fat and sugar, and sodas combine sugar and salt. Beyond satisfying primal cravings, fast food succeeds by offering good value and maximum convenience. Our caveman genetics programmed us to seek variety in our diet, ensuring we obtained diverse nutrients without consciously tracking vitamins or carbohydrates. Similarly, our preference for convenience had survival value-less time spent searching for food meant less exposure to predators. Today, this translates to easy-open packaging, vending machines, drive-throughs, and ready-to-eat options. When investigating whether nutrition information actually influences consumer behavior, Wansink and colleague Pierre Chandon interviewed 250 people after eating at Subway and McDonald's. While 157 Subway customers recalled some nutrition information (versus only 57 at McDonald's), most Subway diners still ordered high-calorie options with cheese, sauce, chips, cookies, and sugary drinks. The average Subway customer underestimated their caloric intake by 34%, believing they consumed 495 calories when actually eating 677. McDonald's customers underestimated by 25%, thinking they ate 876 calories when actually consuming 1,093. Subway's "health halo" created a false confidence that everything on their menu was healthy, leading to more indulgent choices. Low-fat labels create a dangerous health halo effect. When we see "fat-free" or "low-fat," we assume the food is entirely good for us, ignoring calorie content. In studies, people given granola labeled "low-fat" ate 49% more than those eating identical granola labeled "regular"-consuming 84 extra calories. This effect is even more pronounced among overweight people, who ate 46% more chocolate when it carried a low-fat label, while normal-weight people ate only 16% more. We read things into food labels that aren't true, creating "health halos" around products with health claims. In a grocery store study, customers who received nutrition bars with soy health claims not only believed they reduced heart disease risk but also diabetes, cancer, and even birth defects. Some thought the bars could reverse damage from junk food. This happens because we don't carefully analyze labels-we form general impressions about whether something is "good for us" and everything follows from that. Most people ignore serving size information under normal circumstances. When faced with multi-serving packages, we define a serving as whatever we eat in one sitting. In a movie theater study, people ate 39% less granola when the bag was labeled as containing two servings rather than one, though all bags contained the same 640 calories. Individual packaging creates natural portion control-six 100-calorie packs remain six servings, but dump them into one bowl and they become a single serving. The 21st century will be the Century of Behavior Change, where improving everyday habits around nutrition and exercise will be key to extending life quality. While medicine continues making discoveries, changing long-term behavior is essential. Smart marketers could lead this charge by developing enjoyable healthy foods and making exercise less onerous, using creativity and persuasion to motivate us.

Chapter 11

Mindlessly Eating Better

We've gone from Depression breadlines to helping feed post-war Europe to our current obesity epidemic. Critics blame cheap food availability, government subsidies, and sedentary lifestyles for making our environment "obesigenic." Meanwhile, individuals desperately count calories and carbs, moving from diet to diet. Neither extreme offers much hope-changing capitalism is slow, while micromanaging 200 daily food decisions is joylessly unsustainable. Wansink's research suggests the solution lies in the middle: reengineering our personal food environments to help us eat better without constant vigilance. Better eating means different things to different people-eating less, without guilt, more nutritiously, or with greater enjoyment. While "eating right" (as promoted by the American Dietetic Association) is an admirable but daunting goal, "eating better" is something we can start today. Our bodies fight against severe calorie restriction, but they don't notice a 100-200 calorie difference-it doesn't trigger our starvation alarm. There's no universal tip sheet for making positive changes to your eating habits. The power comes from understanding the principles in this book and adapting them to your specific situation. Two effective techniques are food trade-offs and food policies. Food trade-offs state "I can eat x if I do y"-like having dessert if you've worked out or chips if you skip a morning snack. These trade-offs keep you in charge by raising the "price" of overeating without denying yourself foods you love. Food policies are personal rules with no exceptions-like serving yourself 20% less than usual or never eating at your desk. These eliminate mindless habits without requiring difficult decisions in moments of temptation. Most diets fail because they demand too much change at once. Instead, focus on making just three small 100-calorie changes to your daily food routine. Even if you only succeed with one or two changes, you'll still weigh 10-20 pounds less in a year than if you made no changes. To maintain accountability, use a Power of Three checklist-a simple tracking sheet with days across the top and your three changes down the side. Check off what you accomplish each evening. Experts say it takes about 28 days to break an old habit and establish a new one. We can make firm commitments to change our eating habits, but when faced with temptation in a moment of weakness-after a hectic workday or during a special occasion-our resolve often crumbles. We rationalize exceptions: "Today's different," "I'll make up for it tomorrow," or "This is a special occasion." This is the tyranny of the moment, and it wins nearly every time. Only one thing consistently defeats it: habit. The Power of Three Checklist forces us to face facts each night, preventing our selective memories from fooling us about our actual behaviors. Weight loss needn't be a painful sprint. Like walking home from two miles away, slow and steady progress is more comfortable and sustainable than running. By removing unwanted eating cues and rearranging your environment so it works for you rather than against you, you can lose one or two pounds a month without feeling deprived. These comfortable steps add up, and before long you'll reach your goal. As Wansink likes to say, "The best diet is the one you don't know you're on."
