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.
Insulin Ineffectiveness. Now that you know the symptoms of diabetes -- high blood glucose, excessive hunger and thirst, frequent urination -- let's look at what happens to your body during diabetes. For the purposes of this discussion, let's suppose that you have undiagnosed, and therefore unmanaged, diabetes.ow, let's see how the lack of insulin or insulin-resistance affects your body to produce the clinical symptoms and signs of diabetes: Your lack of insulin or insulin resistance directly causes high blood-glucose levels during fasting and after a meal (reduced glucose tolerance).
