Obesity Facts -Globally, there are more than 1 billion [|overweight] adults, 300 million of them are obese -Obesity poses a major risk of chronic diseases such as t[|ype 2 diabetes], [|cardiovascular disease], [|hypertension] and [|stroke], [|osteoarthritis], and some forms of cancer -The main causes of obesity are increased consumption of energy-dense foods high in [|saturated fats] and [|sugars], and reduced physical activity -1 out of every 3 [|Americans] are obese -55% of Americans are overweight or obese -Over the past 20 years, the number of children that are overweight or obese doubled 50%

Pathophysiology -[|Leptin] and [|ghrelin] are the main instances in what controls your body's appetite. Ghrelin tells the stomach to eat when empty and for the stomach to stretch when you are full after eating. Leptin controls the fat storage and whether you need the fat or not. Both of these counteract with each other and control the appetite. When you are obese, your leptin level is resistant and you have very high levels of it. If your body is resistant to it, that will lead to eating more than you need to which causes obesity in people.

BSX -[|BSX] is a link that is what food you put in to your body and your spontaneous physical activity, Activities could include simple as walking or fidgeting while sitting. In the brain, the hypothalamus is where both of these are controlled. It is what is signaled in your brain when you want food and go and get it. Research was done on mice and it concurred that if a mouse lacked BSX, then it was a lot lazier than real mice. BSX could be a target for medicine that will help obesity. Research is still ongoing.
