The second hormone that becomes involved when you begin to lose weight is a hormone known as leptin. Leptin is a hormone that is released from the fat cells to signal to the brain about how much fat we have in storage. To our body this is kind of like the indicator on a car telling us how much fuel we have in the tank. Leptin is also a messenger that is involved with controlling your metabolic rate AND your appetite.
Type 2 diabetes was also previously referred to as non-insulin dependent diabetes mellitus (NIDDM), or adult-onset diabetes mellitus (AODM). In type 2 diabetes, patients can still produce insulin, but do so relatively inadequately for their body's needs, particularly in the face of insulin resistance as discussed above. In many cases this actually means the pancreas produces larger than normal quantities of insulin. A major feature of type 2 diabetes is a lack of sensitivity to insulin by the cells of the body (particularly fat and muscle cells).

Emerging data suggest an important correlation between metabolic syndrome and risk of stroke. [58] Each of the components of metabolic syndrome has been associated with elevated stroke risk, and evidence demonstrates a relationship between the collective metabolic syndrome and risk of ischemic stroke. [59] Metabolic syndrome may also be linked to neuropathy beyond hyperglycemic mechanisms through inflammatory mediators. [60]
