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). The differing energy density of foods (fat, alcohols, carbohydrates and proteins) lies mainly in their varying proportions of carbon, hydrogen, and oxygen atoms.
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.
Too much insulin in the bloodstream can lead to hypoglycemia. And on the other hand, too low insulin can lead to hyperglycemia (too high glucose in the blood). See also the differences between hyperglycemia and hypoglycemia, before continuing! Low blood sugar symptoms without diabetes. The symptoms of hypoglycemia in non-diabetics vary, depending on how far glucose in the blood drops. These may include: 1  You may have paleness. 2  Shakiness and trembling. 3  Having lack of energy, as a result you will feel fatigue, weakness, and have poor coordination.
