The ketogenic diet can also have several disadvantages, most of which depend on the levels of ketone bodies present in the blood:
Increased renal filtration and diuresis (excretion of ketone bodies and nitrogenous waste)
Tendency to dehydration
Increased workload of the kidneys
Possible toxic effect on the kidneys from ketone bodies
Possible hypoglycemia
Possible hypotension
Heachache
Fatigue
Dizziness
Mild nausea
Irritability.
In the most sensitive subjects, increased possibility of fainting (due to the previous two)
Greater tendency to:
Muscle cramps
Constipation
Sensation of heart palpitations
Increased workload of the liver, due to increased neoglucogenesis, transamination and deamination processes
In the presence of intense and/or prolonged motor activity, muscle catabolism
It is unbalanced and tends to limit the intake of some very important nutrients
It can be particularly harmful for:
Malnourished subjects such as, for example, those affected by eating disorders (DCA)
Type I diabetics
Pregnant and nursing
