1. THE CAUSE OF OBESITY what is obesity？ risk of obesuty cause of obesity treatment for obesity

2. what is obesity？ ？ There are many ways in which a person's health in relation to their weight can be classified, but the most widely used method is body mass index (BMI). BMI is a measure of whether you're a healthy weight for your height. You can use the BMI healthy weight calculator to work out your score. For most adults, a BMI of: 18.5 to 24.9 means you're a healthy weight 25 to 29.9 means you're overweight 30 to 39.9 means you're obese 40 or above means you're severely obese Small text

3. risk of obesity It's very important to take steps to tackle obesity because, as well as causing obvious physical changes, it can lead to a number of serious and potentially life- threatening conditions, such as: type 2 diabetes coronary heart disease some types of cancer, such as breast cancer and bowel cancer stroke

4. causes Obesity is generally caused by eating too much and moving too little.However，some main causes are following： 1.calories 2.Poor diet 3.Lack of physical activity 4.Genetics 5.Medical reasons

5. calories Praesent vitae auctor lectus. Etiam congue venenatis rhoncus. Cras neque leo, blandit a urna id, ullamcorper eleifend nisl. Donec tempus interdum dui, vel pretium urna dictum vitae. Interdum et malesuada fames ac ante ipsum primis in faucibus. Sed ac consectetur magna, non congue ante. Mauris consectetur urna diam, eget tristique metus viverra quis. Vestibulum cursus fermentum posuere. Duis sed lectus tristique sapien fermentum mollis. Maecenas lacus nunc, euismod et sem et, gravida consequat magna. Phasellus facilisis metus sit amet mi rutrum sodales. Nullam sit amet lectus id erat ornare feugiat.

6. Poor diet Obesity doesn't happen overnight. It develops gradually over time, as a result of poor diet and lifestyle choices, such as: eating large amounts of processed or fast food – that's high in fat and sugar drinking too much alcohol – alcohol contains a lot of calories, and people who drink heavily are often overweight eating out a lot – you may be tempted to also have a starter or dessert in a restaurant, and the food can be higher in fat and sugar eating larger portions than you need – you may be encouraged to eat too much if your friends or relatives are also eating large portions drinking too many sugary drinks – including soft drinks and fruit juice comfort eating – if you have low self-esteem or feel depressed, you may eat to make yourself feel better Unhealthy eating habits tend to run in families. You may learn bad eating habits from your parents when you're young and continue them into adulthood.

7. Lack of physical activities Lack of physical activity is another important factor related to obesity. Many people have jobs that involve sitting at a desk for most of the day. They also rely on their cars, rather than walking or cycling. For relaxation, many people tend to watch TV, browse the internet or play computer games, and rarely take regular exercise. If you're not active enough, you don't use the energy provided by the food you eat, and the extra energy you consume is stored by the body as fat. The Department of Health recommends that adults do at least 150 minutes (two-and-a- half hours) of moderate-intensity aerobic activity, such as cycling or fast walking, every week. This doesn’t need to be done all in one go, but can be broken down into smaller periods. For example, you could exercise for 30 minutes a day for five days a week. If you're obese and trying to lose weight, you may need to do more exercise than this. It may help to start off slowly and gradually increase the amount of exercise you do each week.

8. Genetic Some people claim there's no point trying to lose weight because "it runs in my family" or "it's in my genes". While there are some rare genetic conditions that can cause obesity, such as Prader-Willi syndrome, there's no reason why most people can't lose weight. It may be true that certain genetic traits inherited from your parents – such as having a large appetite – may make losing weight more difficult, but it certainly doesn't make it impossible. In many cases, obesity is more to do with environmental factors, such as poor eating habits learned during childhood.

9. In some cases, underlying medical conditions may contribute to weight gain. Medical These include: an underactive thyroid gland (hypothyroidism) – where your thyroid gland doesn't produce enough hormones Cushing's syndrome – a rare disorder that causes the over-production of steroid hormones However, if conditions such as these are properly diagnosed and treated, they should pose less of a barrier to weight loss. Certain medicines, including some corticosteroids, medications for epilepsy and diabetes, and some medications used to treat mental illness – including antidepressants and medicines for schizophrenia – can contribute to weight gain. Weight gain can sometimes be a side effect of stopping smoking.

11. TREATMENT The best way to treat obesity is to eat a healthy, reduced-calorie diet and exercise regularly. To do this you should: 1.eat a balanced, calorie-controlled diet as recommended by your GP or weight loss management health professional (such as a dietitian) 2.join a local weight loss group 3.take up activities such as fast walking, jogging, swimming or tennis for 150 to 300 minutes (two-and-a-half to five hours) a week 4.eat slowly and avoid situations where you know you could be tempted to overeat 5.You may also benefit from receiving psychological support from a trained healthcare professional to help change the way you think about food and eating. If lifestyle changes alone don't help you lose weight, a medication called orlistat may be recommended. If taken correctly, this medication works by reducing the amount of fat you absorb during digestion. Your GP will know whether orlistat is suitable for you. In rare cases, weight loss surgery may be recommended.
