One of the keys to living a long and happy life is being physically and mentally healthy. Being obese puts a vast strain on the human body; it forces the heart to pump faster because of the increased amount of body fat. This, as a result, causes high blood pressure and puts unneeded strain on your heart. It has been proven that being obese greatly increases your chances of being diagnosed with diabetes; it is the leading cause of type two diabetes. This is because if there is too much fat in the body then it can become resistant to insulin and without insulin the cells can’t get their needed energy. Obesity is also a contributing factor to some people getting cancer. People who are overweight have a greater risk of developing many different types of cancer.
