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.
Emergency conditions of low blood sugar (hypoglycemia) can be seen if too much insulin is given in relation to food intake. The owner must be aware of when this could occur, the signs of the condition, and how to manage it. A blood sugar level that is too high is better than one that is too low.
