Obesity may increase cancer risk by changing hormone levels

Obesity most likely increases the risk of cancer by raising levels of hormones such as oestrogen and insulin.
In early life, oestrogen is mainly produced by a woman’s ovaries, but this stops after menopause. Instead, fat in the body becomes the main source of oestrogen and obese women have up to twice as much oestrogen as women with a healthy weight. They also have lower levels of SHBG, or ‘sex hormone binding globulin’, which mops up oestrogen in the body 38. This is almost certainly why obesity increases the risk of breast and womb cancers.
Obesity also increases levels of insulin in the body. It’s not clear how this could lead to cancer, although high insulin levels are a common feature of many cancers. High insulin levels could explain why being obese increases the risk of bowel, kidney and pancreatic cancer.
Obesity could also cause cancer through other means, including:
increasing the risk of oesophageal cancer by causing ‘gastric acid reflux’, a condition where the stomach’s acids are briefly pushed back into the throat. This damages the lining of the oesophagus.
increasing the risk of gallstones, which in turn increase the risk of gallbladder cancer.

THE ADVANTAGES OF DIET & EXERCISE

Better Sleep
Increasing your daily activity level and eating healthy will help you get a better night sleep. When the body has the essential nutrients it needs to function properly and is getting the required amount of oxygen from moving, the brain functions better.

Eating healthy and exercising for a minimum of 30 minutes a day can dramatically reduce your risk of many serious diseases.

Increases Energy
Cardiovascular exercise helps circulate oxygen through your body to improve heart and lung efficiency.

Improves Mental Health
Exercise triggers chemicals in the brain called endorphins that help you feel happy and relaxed.

4 Reasons Fast Food Cause Obesity

1. Unhealthy Ingredients Make Fast Food Cause Obesity
Most fast food ingredients contain more energy, total fat, saturated fat, carbohydrates and added sugars than healthier food of the same weight.
2. Larger Portion Sizes Make Fast Food Cause Obesity
As popularized by the 2004 documentary Super Size Me (if you haven't seen it, you can watch it for free here), the problem with the ingredients of fast food is further compounded by fast foods’ growing portion sizes.
3. Low Cost Makes Fast Food Cause Obesity
Researchers at the University of Washington found that a 2,000-calorie diet of junk food costs 10 times less than a 2,000 calorie healthy diet. 6 This low cost of fast food encourages people to choose it over more expensive healthier food, which is a big reason that lower-income individuals are more likely to be obese.
4 Convenience Makes Fast Food Cause Obesity
The final factor that makes fast food cause obesity is its convenience, or more specifically, how close fast food restaurants are to your home, job or school.
