Overweight to Obesity



Obesity is one of the most common self-inflicted diseases of the modern world. People figuratively dig their graves with their teeth. “The longer your belt line, the shorter your life line.” This saying has been around for a long time, and it is true.
The relationship between obesity and disease is well established. The weight increase usually comes in the form of excess carbohydrates and fats. Coronary heart disease is far more common in the overweight. Their blood pressure is usually much higher, and they arc more likely to become diabetic. In short, the overweight are more likely to develop the risk factors that will predispose to premature heart disease and a heart attack. The overweight usually have a marked increase of the blood-fat levels, both of cholesterol and triglycerides, when compared to normal. A reduction in weight invariably reduces the blood pressure, and the lipid levels generally fall significantly.
Many sophisticated nations have a high consumption of beer per capita. In Australia this is about 103 litres per person per year. This significantly raises the obesity level. for beer is high in kilojoules.
Doctors and scientific laboratories around the world now universally use Systente International (SI) when recording scientific figures. This replaces the older system, and will be the one used throughout these volumes.
Instead of mg (milligram), the term millimolle (mmol) will be used. Most figures are quoted as so many mmol in every 100 millilitres (ml) of fluid (eg blood). The currently used term is decilitre (dL), which is the same quantity as 100 ml. For example, for cholesterol, the level may have read 200 mg/ 1.00 ml, which in the new terminology would read 5.2 mmol/L. Similarly, with the energy unit, the caloric, this has been altered. and now the kilojoule (kJ) is used. 1 calorie equals 4.2 kJ. Therefore. a 3000-calorie per day diet would now read 12,600 kJ. It is simply a matter of getting used to the new terms and the new sets of figures.
