The Low Calorie Diet

A liquid based diet that is severely restrictive in energy with an intake of about 800 calories or less per day is considered a very low calorie diet. These diets are an alternative method that moderately to severely obese people may consider for significant, short-term weight loss. Such a diet are recommended  for a relatively short term (3-6 months) and are to be followed only under medical supervision.

Who can benefit from a very low calorie diet?

Low calorie diet is generally safe when used under proper medical supervision in patients with a body mass index (BMI) greater than 30. BMI is a mathematical formula that takes into account both a person's height and weight. Use of Low calorie diet in patients with a BMI of 27 to 30 should be reserved for those who have medical complications resulting from their obesity.

This does not include children, adolescents, pregnant or breast-feeding women, for whom very low calorie diet is not appropriate unless part of a specialized treatment program. Also, people over 50 may not tolerate the side effects associated with Low calorie diet because of preexisting medical conditions or need for other medications.

Low calorie diet is not recommended if you have heart problems, blood clotting problems, bleeding ulcers, liver disease, kidney disease, or cancer or if you have had a stroke.

Benefits Of Low Calorie Diets

A Low calorie diet may allow a severely to moderately obese patient to lose about 3 to 5 pounds per week, for an average total weight loss of 44 pounds over 12weeks. Such a weight loss can improve obesity related medical conditions, including diabetes, high blood pressure, and high cholesterol. Combining a Low calorie diet with behavioral therapy and exercise may also increase weight loss and may slow weight regain.

However, Low calorie diet are no more effective than more modest dietary restrictions in the long-term maintenance of reduced weight.
