New Hope for the Obese

A hormone has been identified that makes a person feel full. This "anti-eating" hormone can be taken orally. It easily gets into the bloodstream. The discovery has been made by a combined team from Murdock University Australia, and Syracuse University in the US. Obese people have less PYY hormone. The treatment is so effective that even naturally thin subjects lost weight.

Normally, PYY is absorbed in the stomach. Researches have found a way of attaching the hormone to vitamin B12 that carries PYY through the stomach into the bloodstream. Some is lost but a significant amount gets through.

The medication will be made available in tablet form and chewing gum. Patients will have to stay on the treatment for a target period: the PYY dose takes up to four hours to get into the system and begin to have an effect. This would mean that patients will have to take a tablet directly after a meal, lunch for example, for it to suppress appetite at tea or dinner.

Childcare Makes Men More Effeminate

Men become more effeminate after marriage. When men marry, particularly when they have children, the level of testosterone in men's bodies falls. Tests on Filipino men highlighted this phenomenon. It appears that the more men care for children, adopting female behavior, the lower their testosterone.

Research subjects were 21 years old on average. They were tested at the beginning and after 4 years. At the latter time 50 per cent were married. These married men had very high testosterone levels initially, which indicates that testosterone makes men more attractive as marriage partners.

Very low testosterone was found in married men with a child less than one month old. Males who cared directly for a child had 80 per cent of the testosterone level of men who left childcare to mothers.

Obviously behavior drives hormone level. This is a new discovery. If testosterone is affected by behavior it is possible that other hormones levels are determined by the way people act.
