Fats and ethanol have the greatest amount of food energy per mass, 37 and 29 kJ/g (8.8 and 6.9 kcal/g), respectively. Proteins and most carbohydrates have about 17 kJ/g (4.1 kcal/g).The differing energy density of foods (fat, alcohols, carbohydrates and proteins) lies mainly in their varying proportions of carbon, hydrogen, and oxygen atoms.Carbohydrates that are not easily absorbed, such as fiber, or lactose in lactose-intolerant individuals, contribute less food energy.roteins and most carbohydrates have about 17 kJ/g (4.1 kcal/g).

An insulin overdose can cause low blood sugar levels (hypoglycemia), which can be quite dangerous. Some of the early symptoms of low blood sugar include: 1  Sweating. 2  Extreme hunger. 3  Dizziness. 4  Cold sweats. 5  Shakiness.  Blurry vision.
In type 1 diabetes, the insulin-producing cells of the pancreas have been largely destroyed. In the absence of insulin, blood sugar becomes too high because it cannot be ushered into the cells to use for energy. This produces the classic diabetes symptoms -- increased thirst, increased appetite and frequent urination. In addition, despite eating more, teens with type 1 diabetes often lose weight in the weeks before being diagnosed, largely due to dehydration but also as a result of loss of muscle and body fat. Symptoms of type 1 diabetes in teens usually occur over several weeks before being checked by a physician.
