With so many diets out there its tough to decide which one is best. I can find a scientific study to support every diet out there. You just need to figure out which one is best for your body, your training and your schedule. Here is an in depth look at  a popular diet called the Ketone Diet. There are positives and negatives about it.


Establishing the metabolic state of ketosis even for a short period of time has many outstanding benefits.

What exactly is Ketosis? The metabolic state of ketosis simply means that the quantity of ketone bodies in the blood have reached higher-than-normal levels. When the body is in a ketogenic state, this means that lipid energy metabolism is intact. The body will start breaking down your own body fat to fuel the body’s normal, everyday functions.

WHAT’S SO GREAT ABOUT BEING IN KETOSIS?

Establishing this metabolic state of ketosis even for a short period of time has many outstanding benefits.

BENEFIT 1

The main benefit of ketosis is that it increases the body’s ability to utilize fats for fuel, which gets very lazy on a high-carbohydrate diet. 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.

BENEFIT 2

Ketosis has a protein-sparing effect, assuming that you are consuming adequate quantities of protein and calories—0.7 grams per pound of body weight per day—in the first place.1 Once in ketosis, the body actually prefers ketones to glucose. Since the body has copious quantities of fat, this means there is no need to oxidize protein to generate glucose through gluconeogenesis.

“Ketosis has a protein-sparing effect, assuming that you are consuming adequate quantities of protein and calories in the first place.”

BENEFIT 3

Another benefit has to do with the low levels of insulin in the body, which causes greater lipolysis and free-glycerol release compared to a normal diet when 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, beneficial hormones are released in the body, such as growth hormone and other powerful growth factors.

BENEFIT 4

Another small but very important benefit of the ketogenic diet is that when in the state of ketosis, ketones, along with a high protein intake, seem to suppress appetite.3 A high-carbohydrate diet, on the other hand, increases hunger levels. Because you have to consume a lot of fat on a ketogenic diet, which hold 9 calories per gram, you are not getting much food volume. It’s not mandatory to be hungry on a reduced-calorie diet.

WHERE IS THE SCIENTIFIC DATA?

Fatty acid production in fat tissue is stimulated by epinephrine and glucagon, and inhibited by insulin. Insulin is one of the hormones the pancreas secretes in the presence of carbohydrates. Insulin’s purpose is to keep blood glucose levels in check by acting like a driver, pushing the glucose into cells. If insulin were not to be secreted, blood glucose levels would get out of control.in-depth-look-at-ketogenic-diets-and-ketosis_07Glucagon is on the other side of the spectrum; it is insulin’s antagonistic hormone. Glucagon is also secreted by the pancreas when glucose levels fall too low. This usually happens when a person skips meals, or does not consume adequate amounts of carbohydrates for an extended period of time. When this happens, glucagon is secreted by the pancreas to break down stored glycogen in the liver into a more usable form, glucose.

When the body’s glycogen stores begin to get depleted, rates of beta-oxidation increase, resulting in the mobilization of free fatty acids from fat tissue. This is where the metabolic state of ketosis comes in. During beta-oxidation, ketone bodies are released from the liver—because they cannot be utilized by the liver—and travel to the brain to be used for fuel. The free fatty acids can then be turned into a usable energy substrate.
