IELTS. Writing. Part 2. Overweight problems

TASK: In some countries the average weight of people is increasing and their levels of health and fitness are decreasing.
What do you think are the causes of these problems and what measures could be taken to solve them?
ANSWER:
Now, it is not news that the population of some countries are experiencing problems with obesity because they are decreasing their level of fitness and health. It is the most common problem in developed countries where the way of life has changed dramatically in comparison to the life of our ancestors, who didn't have such problems.
I think that there are some causes that led to the development of problems with obesdity and health. The first reason, as it was mentioned before, is the changes in people's life. Nowadays, life has become more stressful and people live under constant pressure of problems they faced at their work, public and private life. Some people can't cope with these problems and they lose self-control and eat more than they need. The second reason, from my point of view, is composition of food we eat. It has more sugar, carbohydrates and other high-energy food additions which makes our bodies save excessive energy and keep it as fat, which is very difficult to remove. The next reason is a lack of free time which can be spend for exercising because level of responsibilities for every person has increased and 24 hours is not enough time.
I think advertising a healthy way of life and education about over-eating will be very effective tools in a fight with obesity, because if we provide information about all diseases which people will face in the future they will try to avoid it.
