Weight loss is a concern for millions of Americans caught in the obesity epidemic of recent decades. While many diet plans claim to induce dramatic, rapid weight loss, they are often unhealthy and unsustainable due to overly restrictive rules. Understanding the definition of rapid weight loss helps you identify characteristics of unhealthy weight-loss plans and avoid complications. Consult your doctor before beginning any new weight-loss program.
Features
Rapid weight loss may be measured in pounds or inches lost. It has no definite time or weight limit, and refers rather to weight loss that occurs more quickly than expected. Those who drop weight quickly may suddenly require smaller clothing or hear comments from others regarding their decreasing weight. The causes of rapid weight loss may be known or unknown, and can be desirable or unwanted depending on the individual. When it occurs without an obvious reason, rapid weight loss can sometimes signal an underlying health problem.
Causes
Rapid weight loss can stem from many causes --- the most common being sudden changes in eating or exercise habits. According to the American Heart Association, crash diets that require severe calorie restriction are sometimes effective for rapid weight loss but can lead to health problems like malnutrition. These types of diets are rarely sustainable and often result in rebound weight gain when discontinued. Rapid weight loss that occurs without effort, meanwhile, can signal an underlying health problem. Unexplained weight loss is a potential sign of hyperthyroidism, MayoClinic.com warns. Other possible causes include HIV infection, certain cancers and inflammatory bowel diseases like Crohn's disease and colitis.
Prevention/Solution
When attempting to lose weight, avoid extreme diets and focus on sustainable healthy lifestyle choices. The American Heart Association suggests eating a healthy diet rich in whole grains, fresh fruits and vegetables and low-fat dairy products. In combination with regular exercise, healthy dietary changes can produce significant weight loss over time; a rate of 1 to 2 pounds a week is considered healthy. While you might not see results overnight, a sensible diet and exercise program will provide lasting results without compromising your health. In addition, healthy lifestyle choices do away with the need for crash diets by helping you maintain an ideal weight at all times.
Considerations
In some cases, rapid weight loss can be undesirable or even dangerous. If you experience rapid weight loss accompanied by fever, diarrhea or intestinal pain, seek medical attention to rule out serious health conditions.
