Like most other low-carb diets, the South Beach Diet is divided into three phases: Phase One (14 days), an initial phase during which carbs are particularly restricted; Phase Two during which you may slowly add back carbs that are higher on the glycemic index; Phase Three, beginning when you have reached your ideal weight, which is a long term weight maintenance plan.

In simple terms, the South Beach Diet differs from other low-carb diet programs in that it emphasises the different types of carbs to be consumed, rather than quantities.

However, like many other low-carb plans, greater importance seems to be given to carbs than calories.

The South Beach Diet recommends at least 20 minutes of exercise a day.

It also recommends fish oil supplements.

You need not weigh yourself every day - instead keep an eye on how your clothes are fitting - and, if you start to gain weight, cut back on the carbs.
