Eating mindfully. A child who learns to see food as fuel and not emotional compensation can start to make better choices at mealtime — for example, selecting complex carbs instead of simple carbs (whole-grain instead of white bread, brown rice instead of white); getting more fiber with beans, fruits, and vegetables; choosing "healthy" fats like olive oil and nuts; and avoiding too many empty calories from soda and sweets.
Have you ever eaten a salad with low fat dressing, hold the nuts with a swap for lean protein? Did you leave feeling hungry, unsatisfied and searching for something else to fill you up? When this happens and you end up snacking throughout the day you never have the opportunity to burn fat as fuel because your metabolic hormones are increased and you never enter the fasting stage. No Bueno!
Metabolic syndrome is thought to be caused by adipose tissue dysfunction and insulin resistance. Dysfunctional adipose tissue also plays an important role in the pathogenesis of obesity-related insulin resistance.  Both adipose cell enlargement and infiltration of macrophages into adipose tissue result in the release of proinflammatory cytokines and promote insulin resistance. 
Insulin is vital to patients with type 1 diabetes - they cannot live without a source of exogenous insulin. Without insulin, patients with type 1 diabetes develop severely elevated blood sugar levels. This leads to increased urine glucose, which in turn leads to excessive loss of fluid and electrolytes in the urine. Lack of insulin also causes the inability to store fat and protein along with breakdown of existing fat and protein stores. This dysregulation, results in the process of ketosis and the release of ketones into the blood. Ketones turn the blood acidic, a condition called diabetic ketoacidosis (DKA). Symptoms of diabetic ketoacidosis include nausea, vomiting, and abdominal pain. Without prompt medical treatment, patients with diabetic ketoacidosis can rapidly go into shock, coma, and even death may result.
