Couple of comments about diabetes and obesity.

Diabetes is even more scary than heart disease and is primarily caused by obesity…now Type 2 diabetes is the not the same as Type 1.  Type 1 diabetes is when the body makes no insulin and can happen at any age, any weight.  Type 2 is a result of being overweight, the body struggles to make enough insulin and at some point is not able to make enough, but can make small amounts.  The best way to control diabetes is to control weight and to exercise.  Some people do not have to take any medicine to control diabetes.  But some do. 

According to WHO: “Diabetes is a chronic disease that occurs when the pancreas does not produce enough insulin, or when the body cannot effectively use the insulin it produces. Hyperglycaemia, or raised blood sugar, is a common effect of uncontrolled diabetes and over time leads to serious damage to many of the body's systems, especially the nerves and blood vessels.”
