Continuing weight loss may deteriorate into wasting, a vaguely defined condition called cachexia.[52] Cachexia differs from starvation in part because it involves a systemic inflammatory response.[52] It is associated with poorer outcomes.[47][52][53] In the advanced stages of progressive disease, metabolism can change so that they lose weight even when they are getting what is normally regarded as adequate nutrition and the body cannot compensate. This leads to a condition called anorexia cachexia syndrome (ACS) and additional nutrition or supplementation is unlikely to help.[49] Symptoms of weight loss from ACS include severe weight loss from muscle rather than body fat, loss of appetite and feeling full after eating small amounts, nausea, anemia, weakness and fatigue.[49]
Next comes the science part. Numerous questions are answered, including why weight loss is more difficult for women than men and how to minimize hunger while dieting. Luckily the Venus Factor is designed to optimize weight loss for women specifically. I’m not allowed to reveal all the secrets here, but let’s just say that the book explains how to overcome these biological disadvantages.
In 2008, between US$33 billion and $55 billion was spent annually in the US on weight-loss products and services, including medical procedures and pharmaceuticals, with weight-loss centers taking between 6 and 12 percent of total annual expenditure. Over $1.6 billion a year was spent on weight-loss supplements. About 70 percent of Americans' dieting attempts are of a self-help nature.[36][37]

Lifestyle and work habits partially determine how many calories we need to eat each day. Someone whose job involves heavy physical labor will naturally burn more calories in a day than someone who sits at a desk most of the day (a sedentary job). For people who do not have jobs that require intense physical activity, exercise or increased physical activity can increase the number of calories burned.
