Establishing this metabolic state of ketosis even for a short period of time has many outstanding benefits.
The main benefit of ketosis dieting is that it increases the body’s ability to utilize fats for fuel. When on high carbohydrate diets the body can usually expect an energy source to keep entering the body, but in the state of ketosis the body has to become efficient at mobilizing fats as energy.
One plus of being in a ketogenic state is that if the body has no further use for ketones, they can simply be excreted through urine as a waste bi-product. This means that at times your body will literally be peeing out body fat! This is a novel theme because you body is very efficient at storing energy substrates for later use.
Ketosis has a protein sparing effect, assuming that you are consuming adequate quantities of protein and calories. Once in ketosis, the body actually prefers ketones to glucose. Since the body has copious quanities of fat this means that there is no need to oxidize protein to generate glucose through gluconeogenesis.
Another benefit is that the low levels of insulin in the body cause greater lipolysis and free glycerol release, when compared to a normal diet in which insulin is around 80-120. Insulin has a lipolysis blocking effect, which can inhibit the use of fatty acids as energy. Also when insulin is brought to low levels many beneficial hormones are released in the body such as growth hormone and other powerful growth factors.
A small but very important benefit about the ketosis dieting is that when in the state of ketosis, ketones seem to blunt hunger in many people. Since on the ketogenic diet you have to consume a lot of fat, you will not get as much food volume. This makes not being hungry a very good thing when on the diet.
The final benefit I’ll discuss here is that a ketone body is an inefficient fuel source, due to the fact that when the fatty acid is converted to a ketone body it contains 7 calories. This means that the normal pound of fat has less than 3,500 calories.
