Evidence that Americans are re-examining their diets is abundant. In their article published March 2004, The Los Angeles Times Health Section stated: "In the last few months, food manufacturers have introduced hundreds of low-carb products and are flaunting them in new ad campaigns, with no slowdown in sight. After all, more than 17% of the 10,000 U.S. households surveyed recently by marketing research giant AC Nielsen reported that someone in their residence is currently on a low-carbohydrate diet. 'We're seeing a convergence of food companies, consumers and the government all coming to the conclusion that the way America eats isn't good', concludes Phil Lambert, a Nielsen analyst. "Dollar sales of fresh potatoes, instant rice, orange juice, white bread and cereal have dropped", Nielsen says, "while sales of eggs, nuts, bacon and meat snacks have surged".

There's a growing trend at even fast food restaurants to go "Low Carb". You can now go to your favorite fast-food joint (ie. McDonald's, Carl's Jr, Burger King and many others) and not feel guilty. Many of them offer low-carb versions of their most popular items as well as new meals to choose from.

Experts like the low carb movement, as the Times article also states: "Health experts are now endorsing the move. Many of them have been saying for years that Americans have been consuming far too many carbohydrates, particularly 'high-glycemic' processed products containing an abundance of refined sugars, corn syrup and flours that cause an insulin rush and trigger hunger. But now a number of forces have joined the low-carb movement, pushing the low fat aside. Many experts think it's more than just a fad".
