Unintentional weight loss - Unintentional weight loss can stem from the poor management of type 1 diabetes mellitus, otherwise known as insulin dependent diabetes mellitus (IDDM), which is often caused by an excess amount of glucose and an insufficient amount of insulin in the bloodstream.
When this happens, the release of triglycerides from adipose (fat) tissue and catabolism (breakdown) of amino acids occurs in the muscle tissues as result, it leads to a loss of both fat and lean mass, leading to an overall reduction in the total body weight.
Intentional weight loss - This occurs when individuals strive to lose the total body mass with a view of improving fitness, health and in some cases appearance. In persons who are overweight or obese, therapeutic loss of weight decreases the likelihood of developing diseases such as diabetes, heart disease, high blood pressure, stroke and certain types of cancer.
