Obesity and diabetes are many times interrelated. Approximately 85% of type 2 diabetics are obese. Diabetes is a disease of sugar metabolism so your body actually, in type 2 diabetes has a resistance to insulin. Insulin is the hormone that helps to control the sugar levels in your body. Obesity is a major risk factor for developing diabetes.
The diet that is necessary to help keep your sugars regulated, if you are a diabetic many times will also help you lose weight if you are obese. So you want to try to avoid simple sugars, things like white bread, obviously anything high in sugar. You want to try to eat things with higher protein content perhaps and things that have a lower glycemic index. A low glycemic index would be a type of food that your sugar does not increase substantially after you eat it.
So for example, if you were to eat beans as opposed to a piece of white bread, your sugar would be better controlled after eating the beans, and those are also better food choices, if you're trying to lose weight. The good news is that if you do lose weight, most likely your diabetes will improve and your doctor will be better able to control your sugars. Sometimes diabetes can actually resolve, if you are able to lose a substantial amount of weight. So that's just a little bit about how obesity and diabetes are related.
