Carl's Jr. has the low-carb six dollar burger, TGI Friday's and Subway have developed Atkins-friendly menus and bread companies have admitted that their sales are down. All these factors show that the high-protein diet developed by Dr. Robert C. Atkins more than 30 years ago has become a widespread craze.
The Atkins diet is based on the fact that the human body burns both carbohydrates and then fat for fuel. If carbohydrate intake is significantly cut, the body will revert to burning fat as the primary energy, resulting in weight loss.
Patricia Barber, nutritionist for USC Hospitality Services said the explosion of low-carb products and menus is about hype and does not necessarily create healthier alternatives for consumers.
The Atkins diet can be compared to the low-fat fad in the 1990s, when manufacturers and fast food restaurants created low-fat alternatives to their products, Barber said.
The fad ended as people learned that cutting fat was not effective without other lifestyle changes such as counting calories or exercising.
The Atkins diet is based on a high-protein and high-fat diet and allows for the consumption of eggs, cheese and all fish, poultry and meat products.
Certain vegetables are labeled as being lower in carbohydrates than others and are allowed after the first two weeks of the diet, which is known as the induction phase.
The diet also encourages the consumption of fat as essential to good nutrition, and encourages practices such as not cutting skin off meat and poultry and using butter instead of margarine.
Fruit, other than berries, bread, pasta, grains, starchy vegetables, dairy other than cheese, cream or butter and sugar are strictly prohibited from the diet.
Because of dietary limitations, people should remember that the Atkins diet is meant as a weight loss diet and that is dangerous for athletes because carbohydrates are needed to support an active lifestyle, said Robert Girandola, associate professor of kinesiology.
The Atkins diet does help people lose weight, but people who use the diet are using it as an easy way out, he said.
The diet caters to the sedentary lifestyle of the United States because it does not need physical activity to produce results.
It would be dangerous for active people to be on the Atkins diet, he said. The problem of carbohydrates comes from a culture of over consumption and big portions, Girandola added.
"Because people are consuming so much extra food that carbohydrate is being converted to fat," he said.
This culture of consumption combined with lack of activity is what Girandola and Barber both say is the real problem with the diet of Americans, not carbohydrates in general.
"If you don't get off your butt and you eat whatever you want you are going to have problems no matter what," Girandola said.
Barber agreed that the best bet for maintaining a healthy weight is a balanced diet.
"Don't have a high or low of anything, but have some of everything," she said.
Barber also emphasized that from a nutrition standpoint, dieting often causes more harm that good.
When certain food groups or types of food are not consumed, it creates a lowered metabolism and cuts out certain nutrients. A deficiency of foods containing calcium should especially be a concern for people on the Atkins diet, Barber said.
Some experts are also skeptical about the health risks of the Atkins diet because research into it is very young and researchers do not know what the long-term effects will be in regards to heart disease or cancer, Girandola said.
He also said that people should remember that there are more food concerns and diseases associated with meat products than any other food in our diet, and that there is a myth that our ancient ancestors had high meat diets so it is natural for us to do so too. In contrast he said that a high meat diet is a new-world phenomenon.
For now Atkins looks like it has settled in our mainstream culture, but like any other fad, it will soon fade away as something else takes over the hype, Barber said.
"We got through low-fat, we'll get through high-protein and I'm sure someone is cooking up the next thing," said Barber.
The only thing that will ever stay, she said, is a balanced diet and exercise.
