Normal blood ph is 7.35 - 7.45. a young females decides to go on a diet that includes no carbohydrates. her body begins to burn fat as an energy source in the absence of carbohydrates. unfortunately, waste products of fat breakdown are ketone bodies, which are extremely acidic.
a. would you expect the blood ph of this individual to go up or down as a result of this diet?
b. what are some health risks associated with blood ph falling out of normal range? (at the macromolecular level)

While you are correct about the ketones; there actually 5 other waste products of which four are also acidic.

A) because the byproducts are acidic, it would make the blood more acidic. Acidity brings down the pH level.

B) the biggest risk is going into Ketoacidosis, or access of ketones resulting in a super dangerous acidity level. The acidity will become so potent that the kidneys will begin to push out as much ketones as possible, resulting in Polyuria (lots of urination), eventual dehydration, and then kidney failure. Additionally you will also start to produce deep and rapid exhalations which smell of Acetone so as to try and get rid of the acidity. Because of the water loss and your bodies need for carbohydrates (the process also yields a significantly lower amount of ATP than normally gaining energy from glucose), you will also begin to suffer from polydipsia (excessive thirst) and polyphagi (excess food intake. The condition is also a byproduct of Type 1 diabetic patients
