Obesity & Weight Loss
Obesity is a nonstandard growth of body fat, generally 20% or more over a person's ideal body weight. Obesity is connected with increased risk of disability, illness, and death. The occurrence of excess body fat leads to obesity. The great occurrence of this state, its severe consequences for physical and mental health and the obscurity of treating it make the prevention of obesity a major public health priority.
On the other hand weight loss is a reduction in body weight characterized by a loss of body fat and skeletal muscle. Unintended weight loss is the most general indication of cancer and often a side effect of cancer treatments. A poor response to cancer treatments, reduced quality of life, and shorter survival time may effect from substantial weight loss. The body may become weaker and less capable to stand cancer therapies. As body mass decreases, body functionality declines and may lead to undernourishment, illness, infection, and perhaps death.
