The South Beach diet was developed by a cardiologist,
Arthur Agatston, practicing in the Miami, Florida area. In
some respects similar to the Atkins diet because of its
emphasis on lower amounts of
carbohydrates in the diet, the
South Beach diet was developed for cardiac patients to
lose weight without risking ketosis.
In the initial phase, lasting a few weeks, dieters
severely restrict intake of carbohydrates by eating no
grains or fruits.
After this phase, grain-based foods and fruits are
gradually returned to the diet, although in smaller
amounts than were likely eaten before beginning the diet,
and with a concentration on whole grains rather than
refined flour. The more strict initial phase may be
reinstituted at any time to speed weight loss, but should
not be undertaken long enough to induce ketosis.
