When on a liquid diet, you consume no solid food. Often used for quick weight loss, fasting, detoxification and after surgery, a liquid diet is extremely dangerous and can lead to debilitating health problems such as dizziness, malnutrition and heart damage. Unless specifically advised and monitored by a doctor or dietitian, do not engage in a liquid diet.
Nutritional Information
Liquid diets do not provide you with proper amounts of calories, nutrients, vitamins or minerals. Liquid diets are low in protein, fat, carbohydrates, iron, vitamin B12, vitamin A and thiamine, all of which are essential for human health. When you consume a liquid diet, you are also drastically cutting the number of calories you consume. While this can lead to quick weight loss, it can also result in malnutrition. The fewer calories you put in your body, the less likely it is that you are consuming the proper balance of nutrients necessary for proper health.
Health Effects
Your body loses not only fat but muscle tissue while on a liquid diet. Since muscle requires a high level of metabolic activity, as your body loses muscle mass, your metabolism will slow down. Therefore, when you stop your liquid diet, you will more than likely gain back the weight you've lost. Unfortunately, a slow metabolism is a small concern next to the other health effects of a liquid diet, including sensitivity to cold, diarrhea, heart problems and gallbladder issues. Sudden death is even possible on very-low-calorie liquid diets.
Considerations
After some types of medical procedures and surgeries, such as jaw wiring, some patients may need to consume a full liquid diet as a step between a clear liquid diet, which usually consists of water, and a regular diet. However, medically supervised liquid diets are not only necessary but specially formulated to ensure that patients receive high-quality protein and carbohydrates as well as a variety of vitamins and minerals.
Long-Term Weight Loss
Permanent, healthful weight loss is attained by following a plan that includes a well-balanced diet and exercise. Eat a variety of fresh fruit, vegetables, whole grains, low-fat dairy and lean protein, preferably from plant sources. Embark on an exercise regimen, including aerobic and muscular fitness as well as stretching. Work closely with your doctor or dietitian to come up with a weight loss plan that supports your goals while keeping you strong and healthy.
