What are liquid diets?
Liquid diets control calorie intake by restricting what you eat to mostly or all liquids. How they work varies from product to product. Some liquid diets are fluid only — juices or shakes that replace all of your meals, three or four times a day. These programmes are either do-it-yourself options sold over the counter, or medically supervised plans available only through your doctor or hospitals. Other types of liquid diets replace just one or two meals (usually breakfast and lunch) with drinks, but let you eat a healthy, balanced dinner. These diets may also include snack bars for in-between meals.
