The Atkins Diet, introduced by Dr. Robert Atkins in the 1970's has spurred a legion of low-carb dieters in the United States. For two decades, millions of Americans have restricted their intake of carbohydrates following the teachings of Dr. Atkins. The diet, which was reintroduced in the book Dr. Atkins New Diet Revolution, focuses on the restriction of carbohydrates to 20 grams in an individual's diet at the start of the program and then tailoring his diet to accommodate up to 40-50 grams of carbohydrates during the 'maintenance' phase.

During the first phase or the induction phase, dieters are not allowed to have more than 20 grams of carbohydrates and they also can not have any alcoholic or caffeinated drinks. They must also refrain from consuming starchy foods, bread or even fruits. There are no imposed restrictions on meats and other sources of protein and yet weight-loss is fastest during this period. Later on, more carbohydrates will be allowed in the diet but dieters will be asked to watch their intake of refined grains and sugar. By the time a dieter reaches the Maintenance phase, he would already have been used to making smart food choices and would already know the amount of carbohydrates he can consume that will keep him in top shape.

Proponents of the Atkins Diet claim that the program teaches your body to burn calories more efficiently and as a result is said to lessen fatigue, depression, and muscle pains.
