Obesity.

So, what is obesity? Obesity-it is overweight. when people so fat..or in more official way you can define it as: Heavy accumulation of fat in the body's fat cells to such a serious degree that it rapidly increases the risk of obesity-associated diseases and mortality. An excellent method to measure the obesity is the body mass index(bmi). You can calculate it as your weight(kg) divided by height(m) squared. people with normal bmi are in the gap between 18-25. if your bmi is more than 30, so....be scared...you're fat!!!!
there is some statistics about how dangerous obesity can be for people's health and life expectancy.:
-70% of men and 63% of women in the UK are obese.
-obesity reduses the life time for about 9 years
-obesity causes 30000 deaths a year in the UK
So,don't eat junk food and don't drink disgusting feezy drinks!!
Why does it happen?
because:
1) changed lifestyles:people eat more,move less,mostly sitting, also the size of dishes in cafes and bistros grew up.
2) The fallen price for processed food,because of using economies of scale:this type of food cheaper that healthy and organic food.
3)calories: people eat more calories and reduced the everyday exercises.
4)A rise in relative poverty: nowadays we also have poor families, who cannot afford themselves a expensive and healthy food,so they "forced" to buy cheap and junk food(over salted and high fat)
5)biffer portions: last decade there has been an increase in portion sizes over for 30%. moreover people became addicted of fast-food,wich makes the problem of obesity more difficult.
Also there is market failure, because of negative externalities:
people are obeese,they lost their power to work, so there is less workforce in labour market.Moreover The government spends extra money on NHS to help to reduce obesity.We have at the same time information failure(wich is also one of the causes of market failure).People don't know what food is bad and what is healthy,don't sometimes realise wich food they should eat..
What the government can do to reduse obesity among people? Here is some ways to do that:
-tax on high-fat food
- give subsidy on healthy food,or reduce the cost of that meal
-persuade the food producers to decrease food sizes
-a ban on advertising junk food
- labelling on food packs,(to reduce information failure)
-Government provisions of water fountains in schools-proper hydration has an effect appetite and reduse the demand for fizzy drinks.
-increase spending on exercise programmes in school
-subsidies for cholesterol busting such as statins to reduce some of the problems associated with clinical obesity.
