Abstract
The prevalence of type two diabetes (T2D) has been
increasing sharply worldwide. Many recent studies have
been done to determine the efectve strategies for beter
management of type two diabetes. One of these
strategies was the Ketogenic Diet, which when performed
on rats and human showed very impressive results. The
benefts of having some ketone bodies circulatng in the
body have numerous benefts such as weight loss,
improvement of HbA1c levels, reversal of nephropathy,
cardiac benefts and treatment for dyslipidemia.

Introducton
According to the latest data by the World Health
Organizaton, approximately 366 million people will have
diabetes by the year 2030 [1]. Several studies have shown a
strong associaton between being overweight and the risk of
developing diabetes. In fact, according to the US center for
Disease control and Preventon, 85% of the diabetc patents
are overweight and 55% are obese [2]. For weight loss, it
became well known that the energy intake should be
decreased and the energy expenditure should be increased.
Several interventons have been proposed for decreasing
energy intake such as bariatric surgeries, pharmacological
usage, and decreasing caloric intake while enhancing energy
expenditure to achieve weight loss [3]. Yet, recent studies
showed that most of the obesity interventons tend to fail in
the long term, especially those that have previously focused
on reducing dietary fat [4]. However, recently, several studies
have showed the benefts of ketogenic diet in overweight
diabetc populaton [2-14]. This review will discuss the
physiological foundaton of ketogenic diet and their efects on
patents with type 2 diabetes.
Discussion
Physiological aspect of ketogenic diet
Ketogenic diet is a diet that is very low in carbohydrates
which results in high circulaton of ketone bodies in the body.
Usually afer 3 days of fastng, or having a dietary intake of
carbohydrates less than 20 grams per day, fat oxidaton
through Krebs cycles will be stopped due to the lack of
producton of oxaloacetate since glucose is needed with
pyruvate carboxylase for the carboxylaton of pyruvic acid
through ATP to produce oxaloacetate [4].
Moreover, the central nervous system requires glucose as an
energy source and thus following a ketogenic diet will cause
the need for an alternatve energy source which is derived
from the overproducton of acetyl-CoA namely ketone bodies.
Ketone bodies are made up of acetoacetate, B-hydroxybutric
acid and acetone. This whole process occurs in the matrix of
liver and is called ketogenesis. Under normal diet, the
concentraton of ketones bodies is less than 0.3 mmol/l and
ketone bodies will not be used as an energy source by the
central nervous system untl this concentraton reaches 4
mmol/l, similar to the glucose concentraton. At that point,
ketone bodies are then used as a source of energy by the all
tssues. Specifcally, B-hydroxybutric acid is transformed into
acetoacetyl-coA which is then transformed into two molecules
of actely-coA which are used in Krebs cycle. The maximum
ketone bodies concentraton in individuals following the
ketogenic diet will reach to 8 mmol/l [4].
However, it is important to note that glucose is also formed
from two sources: glycogenic amino acids and glycerol. In fact,
afer few days of complete fastng, glycerol can produce
around 60% of the body glucose [4].
Benefts of ketogenic diet with type 2 diabetes
Several studies have shown the benefts of ketogenic diet
for patents with type two diabetes, such as weight loss,
reducing hbaA1c, reversing nephrology, cardiac benefts,
improvement of lipid profle and even have potental efect on
reversing diabetc neuropathy and retnopathy [5].
