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.
