High fat diet and ketones

Was wondering, if ketoacidosis manifests as a result of your body processing fat for energy. Is there a danger of one's blood changing in acidity as a result of a low carb, high fat diet?
 
Ketoacidosis is different to ketosis. The first is dangerous, the second is a result of having a very low carb diet, which results in the body burning fat stores.

I bet Borofergie will explain it all properly.
 
That is correct. As far as I know ketoacidosis is caused by high blood sugars over a period of time.

I am sorry I can`t give you a better reply, but within a week of starting a low carb, high fat, diet, all my BG`s were normal. I have never even had a reading in double figures since I have owned my own meter, and selfishly I tend to concentrate on my own health and not read up so much about problems I haven`t got.

If you look lower down on this page there are a few more topics that may interest you. I hope that is of some small help to you.
 
Ketoacidosis occurs as a response to too little insulin. Since Type 2s still produce insulin, it doesn't usually occur.

Wikipedia lists the causes of this dangerous condition for Type 1's :

intercurrent illness (pneumonia, influenza, gastroenteritis, a urinary tract infection), pregnancy, inadequate insulin administration (e.g. defective insulin pen device), myocardial infarction (heart attack), stroke or the use of cocaine. Young patients with recurrent episodes of DKA may have an underlying eating disorder, or may be using insufficient insulin for fear that it will cause weight gain

Ketoacidosis causes the formation of ACIDIC ketone bodies. These are different from the ketones produced during ketosis, as happens on a very low carb diet, when the body uses fat for fuel.

The key to understanding the difference between the two is that only one is to do with too little insulin.
Since you're a Type 2, there's little danger of you developing ketoacidosis :D

Thanks!

Should I watch out for ketones in my pee though?

You should only be worried if you think that you might be an undiagnosed T1. For a regular T2 (not on insulin) ketones aren't much to worry about (in fact some of us are pleased when we get them). Ketones are an alternative energy source for your brain, instead of glucose, on a very-low-carb diet.

What are your BG levels like? How much carbohydrate are you eating?

You'd have to be eating <<50g of carb a day to be spilling ketones in your urine.
 
The acidosis of diabetic ketoacidosis; is a result of large numbers of ketones, making the blood acidic.
There is no difference between the ketones that arise from metabolising fat on a low carb diet and those that arise as a result of a lack of insulin. It is one of the roles of insulin to control the release of fat from the cells: no insulin and no brakes. ... if you have enough of your own then it will normally control this breakdown of fat and production of high levels of ketones.

In T1s with almost no insulin, there is no such control and ketones can rise very rapidly.




1)It also doesn't need much insulin to keep this process semi-controlled; that's why many people with LADA or even before the diagnosis of classic T1 can lose a lot of weight through ketosis but don't get DKA until they have lost quite a lot of their insulin production and the metabolism goes haywire.
