Very low-calorie diets are intended for patients whose body mass index (BMI) is greater than 30 with significant complications such as diabetes or high blood pressure. Unfortunately, following a very-low-calorie diet for quick weight loss can be unhealthy as well as counterproductive, and anyone attempting such a diet for more than a day or two should be monitored closely by a physician. VLC diets are not normally used for patients with a BMI between 27 and 30 unless they have medical conditions related to their weight. Calories are a measure of the amount of energy supplied by food and beverages. In most cases, liquid shakes or meal replacement bars replace food for a period of time ranging from several weeks to several months. Though it may be tempting to create a major calorie deficit in an effort to speed up your loss, very-low-calorie diets generally do more harm than good. Strength training could offset some of the lean muscle loss, but dieters often lack energy for such activity when consuming so few calories. Weight Loss on a Very Low-Calorie Diet An obese patient can lose about three to five pounds per week while following a VLC diet. Another health problem that can be brought on by rapid weight loss -- defined by the National Institute of Diabetes and Digestive and Kidney Diseases as losing more than 3 pounds per week -- is that it significantly increases your risk of developing gallstones. In much the same way, going into caloric excess -- or routinely eating more calories than your body uses -- can cause you to pack on pounds over time.

A physician should decide on a case-by-case basis whether or not a VLC diet is appropriate for a patient. VLCDs are designed to produce rapid weight loss at the beginning of a weight loss program.
Because a pound of fat stores 3,500 calories, creating a 3,500-calorie deficit generally results in a 1-pound weight loss. This amount of weight loss can significantly improve obesity-related medical conditions, such as diabetes, high blood pressure, and high cholesterol. The diets are often used to help obese patients achieve significant, short-term weight loss as part of a comprehensive weight loss program. The average adult needs somewhere in the range of 1,600 to 3,000 calories per day, according to the Center for Nutrition Policy and Promotion. VLC diets are not usually prescribed for children or teens. Patients on a very low-calorie diet usually consume about 800 calories a day. The bars and shakes used in VLCDs are not the same as diet bars and shakes that you can purchase in the grocery store. Shifting into caloric deficit -- or eating fewer calories than your body requires, causing it to burn fat to meet its energy needs -- is the basic principle behind weight loss. The average weight loss for a 12-week VLCD is about 44 pounds. Staying in caloric balance -- or consuming just the level of calories your body needs to meet its basic metabolic requirements and sustain your overall activity level -- plays a major role in your ability to maintain your body weight. Some VLC diets include lean proteins, such as fish and chicken. Side Effects of VLCDs Many patients who follow a VLC diet for four to 16 weeks experience side effects such as fatigue, constipation, nausea, or diarrhea. Cutting calories is an important part of virtually any successful weight-loss plan.
