Explanation:

Weight loss process should be followed with caution without the use of short tricks. If the weight was gained in a period of time, attempts should not be made to lose it fast. Often the short trick methods do not reduce the fat content in body. They only reduce the water weight and lead to muscle loss. Such a weight loss is harmful and it is also not persistent. On resuming normal diet, all of this weight and more can be gained back. Hence, when weight is lost over time using healthy diet and exercise, it is permanent in nature and also more effective and good for overall health.
