Elsewhere in the forum it's been noted that UK women are " fattest in Europe ".
Obesity ( Body Mass Index / BMI more than 30 - BMI correlates fairly well with obesity ) affects about 1 / 4 adult males and females in the UK and also the Philippines, more in the USA, and possibly 500 million in the world as a whole.
The other side of the coin, malnourishment, is still a problem in the Philippines, such that there is a similar proportion of children and adults with malnourishment as obesity in different regions.
There are many health problems arising from the wrong diet, too much or too little of the right food. These include diabetes, heart disease, certain cancers, joint diseases - not forgetting poor self - esteem and depression. That's because most diets - and many health campaigns including responsible marketing by firms with labelling and reducing salt, sugar and fat content of foods - have not proved successful. It's accepted that gaining weight is far easier than losing it. "Eat less and exercise more" is not working for a quarter of our population. Treating obesity in the UK accounts for around 4% of the NHS budget. Here we spend 10% of our GDP on health ; it's less than 1% in the Philippines.
Tobacco and alcohol sales generate revenue from taxation. In this country it's more than the direct NHS cost of treatment, but probably less than the total indirect / social cost. Illegal drugs generate nothing and cost a fortune, but that's another matter.
In October Denmark became the first country in the world to impose a tax on fatty foods. Any food with a saturated fat content of more than 2.3% is taxed at a rate of 16 kroner / kg ( 1.85 GBP ) of saturated fat - adding about 25p to a pack of butter and 8p to a pack of crisps.
Denmark has a far lower rate of obesity than the UK. A minority of other countries are now looking at taxing unhealthy foods. David Cameron mentioned it during the Conservative Conference in October.
The theory is that taxes would reduce consumption of unhealthy foods, contribute to the cost of treating complications of obesity - and, in the Philippines for example, subsidise purchase of staple foods like rice, other vegetables and fruit.
Of course the idea of a fat tax could be criticised as another example of the " nanny state ", and that it might affect the poor more than affluent members of the population.
Obesity is one of the biggest health challenges facing the UK and many other countries. It's become a lifestyle choice which individuals ( through self control ) and health services are finding increasingly hard to carry, literally .
