'Why Am I Fat?'

8 reasons you may be eating too much.

5 min read

You're stuffed after a big restaurant dinner -- but then the dessert cartrolls around, and you just have to order that gorgeous chocolate mousse.Or you're munching from a big bag of chips while checking emails, and when youlook up, the bag is empty. Sound familiar? 

Environmental factors -- like package size, portion size, the variety offood you're served, and the size of your plate -- can influence your eatingmore than you realize, experts say. Indeed, if we always ate only when we werereally hungry and stopped when we were full, there would be no obesity epidemic.

The key, experts say, is to become more aware of these causes of overeating,which can help you resist the temptations and avoid weight gain.

"Once you become aware of the environmental cues that can sabotage yourdiet, you can react accordingly and make smart decisions," says nutritionexpert Susan Moores, RD. Simple things such as bringing tempting snacks intoyour house, moving the candy jar at work out of sight, making fruits and vegetables more visible in yourrefrigerator, and eating more deliberately and slowly, can cut down onovereating and help you lose weight, Moores says.

Here are eight factors that can cause overeating and weight gain:

Overeating can be triggered by the alluring smell of bacon cooking, thesound of popcorn popping, advertisements for junk food, and so on. "You areinfluenced by your surroundings, and our studies show these kinds of cuesresult in eating more food," says Cornell University researcher Brian Wansink,PhD, author of Mindful Eating.

"Eating amnesia" is the act of almost unconsciously putting food in yourmouth, usually from a big bag or bowl while sitting in front of the television,reading a book, checking emails, or during happy hour.

It's also easy not to register the tastes you take while cooking, or thoselast few bites from the kids' plates that you finish off. 

Multi-tasking can lead to overeating because you're not paying attention towhat you are eating. When you eat more mindfully, you really taste the food --and are more likely to feel satisfied sooner. "Food should touch more of yoursenses to be satisfying, instead of just filling in the hole," Moores says.

Everywhere you turn, there are opportunities to eat -- at drive-throughrestaurants, vending machines, even gas stations. And when food is in front ofus, we tend to eat more of it, experts say.

Wansink and colleagues found that when candy was easily accessible onworkers' desks, they ate an average of nine pieces a day, and didn't realizehow many they ate. But when the candy was kept in their desk drawers, they ateabout six pieces per day. And when they had to get up from their desks to reachthe candy six feet away, they only ate four pieces.

Curb your instinct to overeat sweets and snacks by moving them out of sight-- and putting more healthful foods into plain view. Resist the urge to splurgeon unhealthy foods by carrying your own healthy snacks.

Fast-food restaurants on every corner offering inexpensive food alsoencourage us to eat more and more often. Combo meal deals sound like a bargain,but they are loaded with fat, sodium, and calories.

Also, "when you eat lots of fast food, it all starts to taste the same, andyou can become satisfied with a small range of flavors and sometimes it is hardto get enough," says Moores.

To help yourself resist the temptation, work on developing a taste for thesubtle, natural flavors of food, suggests Moores.

Dietitians recommend limiting visits to fast-food restaurants to once aweek. And, they say, choose the healthier menu options -- like salads andgrilled chicken sandwiches -- even if they cost a little more.

Our idea of a normal portion has become skewed, in part because so manyrestaurants serve oversized portions. "Giant portions seem to have evolved intothe norm, and many people have trouble understanding how much they should eat,"Moores says.

To understand what a portion should look like, pull out the measuring cups,and see how your portions stack up against WebMD's Portion SizePlate tool or the standards from the U.S. government's mypyramid.govweb site.

Another answer to the portion dilemma is to eat more foods that are lesscalorically dense. These are foods that contain lots of water and fiber, butnot many calories -- like fruits, vegetables, salads, and broth-based soups.Researcher Barbara Rolls, PhD, and colleagues at Penn State University foundthat it's possible to reduce calories without increasing hunger by eating more of these types of foods.

Mindful eating can help here, too. "Eat slowly, taste the food and becomemore in touch with what you are eating and how it tastes so you can enjoy itmore and start to appreciate satisfaction with smaller portions," Mooressays.

You'll find plenty of bargains on mega-sized packages at super-discountstores like Costco or Sam's. But unfortunately, experts say, these giantcontainers can affect us on an unconscious level and cause us to eat more.Researchers have found that when you eat from a large container, you are likelyto consume 25% to 50% more than you would from a smaller package -- especiallywhen you're eating snacks and sweets.

"First, try to get out of the habit of always eating something while you aresitting, relaxing, or watching television," says American Dietetic Associationspokeswoman Tara Gidus, MS, RD. "Try a cup of tea, glass of water, or chew apiece of sugarless gum. If you want a snack, portion it out of the bag orcontainer or buy smaller packages like the 100-calorie snack packs."

Researchers have found that we tend to eat more when we're served fromlarger containers. Wansink and colleagues found that when students were givenfood in larger bowls, they served themselves 53% more and consumed 56% morethan those who used smaller bowls.

When you use smaller bowls, plates, spoons, and cups, you won't feeldeprived because the food will look more plentiful, Wansink says. Daintierdishware and smaller utensils can also help slow your eating.

A buffet restaurant can be a dieter's nightmare. Too many choices encourageshaving a taste (or more) of everything, and before you know it, your platerunneth over. "Too much variety on your plate at one meal can often mean toomuch food overall," says Connie Diekman, MEd, RD, director of nutrition at Washington University and past president ofthe American Dietetic Association.

So use variety to help meet your nutritional needs, but concentrate on theright foods. Eating a variety of foods is great, as long as the foods are lowin calories and rich in nutrients -- like fruits, beans, vegetables, brothsoups, whole grains, and low-fat dairy.
