3. Rapid Weight Loss………. Losing weight can be very beneficial for your long-term health if you're overweight. However, it's important to do it at a sensible pace, as very rapid weight loss can lead to serious health complications and "yo-yo" dieting in the future . A healthy and sustainable rate of fat loss is roughly 1 to 2 pounds per week. You can achieve this by creating a caloric deficit of 500 to 1,000 calories per day. Combine a healthy diet with regular exercise to lose weight without experiencing the negative health effects of overly rapid weight loss.

4. Ways & Means of Wt. Reduction According to The Obesity Society, 64 percent of American adults are overweight with 31 percent of them considered obese. Many people are trying to lose weight by : dieting exercising surgery drugs combination of weight loss methods

5. Ways & Means of Wt. Reduction ….. Despite the fact it may have taken years to gain weight, many people try to lose weight too quickly by over exercising or following very-low-calorie or crash diets. Crash diets may result in rapid initial weight loss but may have a negative effect on long-term health and diet compliance

6. Harmful Effect of Rapid Weight Loss 1. Fat Mass and Signaling Hormones Your body fat levels are directly proportional to a signaling hormone called leptin . Leptin levels are monitored by the hypothalamus section of your brain. Leptin controls appetite, modulates your metabolism and promotes fat burning. If fat levels drop very quickly, there is a subsequent rapid drop in leptin levels. A rapid drop in leptin levels will trigger the starvation response.

7. 2. The Starvation Response The starvation response is the term used to describe what happens within your body as a result of rapid drops in leptin . The starvation response causes a reduction in your daily energy expenditure by lowering your metabolism, increasing hunger and also prompting the breakdown of muscle for energy. In addition, the starvation response works to ensure you regain not only the fat you have lost, but also some extra fat to protect you from similar bouts of food restriction . This results in a cycle of weight loss/weight gain often referred to as yo-yo dieting.

8. 3. Health Risks Very-low-calorie diets that result in rapid weight loss are often dangerously low in essential nutrients, including vitamins and minerals. A lack of vitamins can lead to a host of health problems, including immune system suppression and bad skin, hair and nails. Chronic mineral deficiencies may also have long-term effects on your health. A lack of essential minerals can lead to fluid imbalances, cardiac arrhythmia or an irregular heart beat, muscle cramps and loss of bone mass.

9. 4. Psychological Complications Very-low-calorie diets may result in a rapid initial weight loss but many dieters find that the severe hunger associated with eating so little food makes it hard to stick with this type of eating program for long periods of time. Hunger levels may become so severe that the dieter falls into a diet/binge cycle of eating. Crash dieting may lead to eating disorders like anorexia and bulimia. A very-low-calorie diet can also be socially exclusive, especially if friends and family are eating normally.

10. 5. Loose Skin Rapid weight loss often leaves loose skin on the abdomen, arms and legs. This happens because the skin has lost some elasticity and did not have time to shrink with the rest of the body. While this may not have long-term health consequences, it can cause mental distress, as well as uncomfortable chafing. The Columbia University Health Center advises that if the skin has not contoured naturally to the body two years after the weight loss, surgery may be the only option to correct it.

11. 6. Gallstones A common side effect of rapid weight loss is the development of gallstones -- hard deposits of cholesterol that form in the gallbladder. They can be harmless, but many people experience nausea and serious abdominal pain from gallstones, to the extent that the gallbladder may need to be removed. According to the Weight-Control Information Network, being overweight or obese makes it more likely that you will develop gallstones, so losing weight is beneficial. However, doing it very quickly actually increases your risk of developing them.

12. 7. Liver Issues While fatty liver disease is commonly associated with obesity, rapid weight loss is a risk factor for developing liver damage, sometimes following surgery to reduce weight in obese patients. This may be due to the sudden changes in your fatty acid profile after your weight loss, or as a residual effect of being overweight.

13. What is Safe Weight Loss To avoid losing weight too fast, most diet experts agree that a moderate reduction in food intake combined with a moderate increase in physical activity is best. By eating 250 fewer calories per day and engaging in exercise that results in 250 extra calories being burned there is a net loss of 500 calories per day, or 3,500 per week. This will result in a weight loss of around 1 pound per week. This slow and gradual weight loss will be sustainable, will not trigger the starvation response and will have no negative impacts on your health.

14. Loss of Lean Muscle When you lose weight very quickly, it's not necessarily just fat that goes. According to a study published in the journal "Appetite" in June 2012, rapid weight loss can also result in a significant reduction in fat-free mass -- lean muscle tissue and bone. This reduction in fat-free mass can lead to a slowing of the metabolism, which can cause a rebound effect when you stop restricting calories or exercising.
