No matter that First Lady Michelle Obama has been on a crusade for a year and a half to slim down the country. Never mind that some restaurants have started listing calories on their menus. Forget even that we keep saying we want to eat healthy. When Americans eat out, we order burgers and fries anyway.
"If I wanted something healthy, I would not even stop in at McDonald's," says Jonathan Ryfiak, 24, a New York trapeze instructor who watches his diet at home but orders comfort foods like chicken nuggets and fries when he hits a fast-food joint.
In a country where more than two-thirds of the population is overweight or obese, food choices are often made on impulse, not intellect. So, while 47 percent of Americans say they'd like restaurants to offer healthier items like salads and baked potatoes, only 23 percent tend to order those foods, according to a survey last year by food research firm Technomic.
That explains the popularity of KFC's Double Down, a sandwich of bacon and cheese slapped between two slabs of fried chicken. It's the reason IHOP offers a Simple & Fit menu with yogurt and fruit bowls, but its top seller remains a 1,180-calorie breakfast sampler of eggs, bacon, sausage, ham, hash browns and pancakes. It's also why only 11 percent of parents ordered apple slices as an alternative to fries in McDonald's Happy Meals.
The mixed message hasn't stopped many restaurants from offering healthier fare. After all, the government has stepped up its oversight - and influence - over the industry that it blames for America's expanding waistline. National rules about putting calorie information on menus are expected to take effect next year and Mrs. Obama touts restaurants and companies that slash calories in foods.
But revamping a menu can be difficult and expensive, requiring months or even years. It took Dunkin' Donuts four years to figure out how to make its doughnuts without trans fat - which doctors say is one of the unhealthiest types of fat - without altering the taste. And efforts to curb unhealthy eating aren't always fruitful. In 2009, a year after New York made chains start listing calories on menus, only 15 percent of diners ordered lower-calorie foods, according to a study in the British Medical Journal.
Most restaurants won't share specifics about how their salads and veggie omelets compete when they're up against burgers and crepes. But the healthy stuff appears to be only a small proportion of revenue at most chains.
The IHOP pancake house, owned by DineEquity Inc., says that Simple & Fit sales have roughly doubled in the year since the menu was introduced. But it still makes up only a single-digit percentage of revenue.
The Cheesecake Factory, which introduced a "Skinnylicious" menu in August featuring entrees with 590 calories or less, says those foods have also performed well. But sales of its decadent cheesecakes are up too. "We recognize that `cheesecake' is in our name," said Alethea Rowe, senior director of restaurant marketing.
There's a host of reasons for the disparity between word and deed. Sometimes people who eat healthy at home want to treat themselves when they go out. Others doubt that the so-called healthier items on fast-food menus are really healthy. Even peer pressure can play a role.
Jason Sierra, who was eating a Whopper hamburger and fries at a Burger King in New York recently, said he's cut back on unhealthy foods because his cholesterol and blood pressure were getting too high. But when his office buddies order lunch, he opts for "man food" like pizza to fit in.
"One day I did try to order a salad," said Sierra, 40, who works in tech support. "And I caught hell for that."
Healthier foods also are usually among the most expensive menu items, which can be tough for recession-weary customers to stomach. Efrain Vasquez and his wife, Evelyn, were recently eating fried chicken and gravy-drenched mashed potatoes at a KFC in New York. They say there's a big difference between a $2 burger and a $6 salad when you're on a tight budget.
"We've got bills to pay," said Efrain Vasquez, 51, a maintenance worker who's raising four kids with Evelyn, a 37-year-old receptionist. "We try to economize."
Like so many American dieters, fast-food restaurants have tried and failed to go healthy. The Wendy's Co. burger chain led the way in the mid-1980s with a short-lived effort to sell tomato halves filled with cottage cheese and pineapple chunks on lettuce leaves.
"Consumers weren't ready for it," said Denny Lynch, a spokesman for Wendy's, where burgers and chicken are the biggest sellers. "Or at least they certainly didn't buy it."
In 2003, during the low-carb Atkins diet craze, Domino's Pizza Inc. couldn't get people to bite on a low-carb pizza it tested in Indianapolis. "While many people at the time made their voice heard that they wanted it, few people actually ordered it," said Chris Brandon, Domino's spokesman.
McDonald's, the world's largest burger chain, says the fruit smoothies and oatmeal with brown sugar and raisins it rolled out last year are selling well, although it declined to disclose their revenue. "We would not have them on the menu if we were not selling them at a rate that we could sustain them at," said Molly Starmann, director of McDonald's family business category.
But the chain didn't always have such luck. It spent three years developing the McLean Deluxe, a 91-percent fat-free hamburger it introduced in 1991 only to suffer disappointing sales.
More recently, McDonald's got a lukewarm response when in 2004 it began offering parents the option of choosing apple slices instead of fries for Happy Meals. So, in July, McDonald's said it would stop offering a choice and instead serve a half portion of both. It had considered taking fries out Happy Meals completely, but nixed the idea when parents in tests said "No."
Restaurants continue to straddle the line.
Burger King Corp. this summer pledged to promote healthier foods for kids, but announced last week that it would sell ice cream desserts nationwide, including an Oreo brownie sundae with 530 calories and 17 grams of fat. KFC introduced grilled chicken in 2009, then launched the Double Down sandwich the following year. The 540-calorie, 32-grams-of-fat breadless sandwich started as a limited-time offering, but proved so popular that the chain ended up keeping it.
Andy Puzder, CEO of CKE Restaurants Inc., which runs the Hardee's and Carl's Jr. fast-food chains, said even though his restaurants offer salads and turkey burgers, he figures his best seller at Hardee's is probably the Thickburger. The most decadent version of it comes with two types of cheese, fried onions, mayonnaise and nearly half a pound of beef and weighs in at 1,170 calories and 83 grams of fat. (The government recommends that most people consume 2,000 calories and no more than about 70 grams of fat each day.)
"We have wonderful, healthy foods if people want to buy them," Puzder said. "But they don't sell particularly well."
