Now, let's see how the lack of insulin as seen in Type 1 diabetes and the insulin resistance of type 2 DM affect your body to produce the typical signs and symptoms associated with diabetes.
The lack of insulin or insulin resistance directly causes high blood glucose levels both after a meal and also during times of "fasting".
Because your cells have no glucose coming into them from your blood, your body "thinks" that it is starving. You feel tired because your cells cannot absorb glucose, leaving them with nothing to burn for energy.
The ketones in the blood and urine seen above are usually associated with Type 1 diabetes but can occur in people with Type 2 diabetes also.
In order to make ATP for energy, the body breaks down mostly carbs, some fats and very small amounts of protein. First let’s do a quick review of things you already know because it is assumed you learned cell respiration already and how glucose levels are regulated in your blood! Glucose breaks down to form phosphoglycerate (PGAL) and then pyruvic acid.  What do we call this process of splitting glucose into two pyruvic sugars? Proteins are the least favorite food to use as energy but if the body needs to, it will.  Proteins are made up of amino acids so when they are digested, we are left with hundreds or thousands of amino acids.
The picture to your right reminds you of what an amino acid looks like.  It begins with a carbon atom, attached to one side is an amino group, on the other side is an acid group (COOH), third a hydrogen. If we are going to turn amino acids into sugars, we have to remove this nitrogen to turn it into sugar. Acetone has a characteristic smell and was the most common chemical used in nail polish remover.
As a future nurse or clinical professional, before they run lab tests, you’ll be taking down the case history. People who have diabetes can go to a drug store and take a dipstick to take a sample of their urine. Anytime you break down fats and proteins, ketoacids increase which is known as ketonemia (-emia mean in the blood) or ketosis (build up of keto acids in the blood stream).
The fact that sugars and ketoacids are coming out their urine osmotically causes water to come out of their urine as well. This is a great article- I understand why it is dangerous for an insulin-dependent Diabetic to be in ketoacidosis, but am confused as to whether a slightly ketotic diet (pure proteins, fat and fibrous non-starchy vegetables) is recommended for weight loss, fitness and prevention of Diabetes…? Yes, the body can make energy from fat and protein, but it’s quite clear that this inhibits energy production.
I think the real issue at hand is PUFA, which is hard for the body to metabolize and which is incredibly unstable and creates ROS. I’m taking biology 111 this year in college and our topic this week was cellular respiration.
So in diabetic ketoacidosis the problem is the body overproduces ketones because the cells are insulin resistant and can’t receive glucose so it switches to fats as fuel. Hello, my name is Antranik and I have a passion for all things relating to the body and mind.

Right after a meal, there is no insulin to act as the key to allow the glucose to enter the cells, as we have seen above and this leads to raised blood glucose values. High blood-glucose levels increase the osmotic pressure of your blood and directly stimulate the thirst receptors in your brain.
It's not clear exactly what stimulates your hunger centers, possibly the lack of insulin or high glucagon levels. The hormone that promotes this process is insulin.  Then when glycogen needs to be broken down, the hormone glucagon, promotes glycogenolysis (Glycogen-o-lysis) to break apart the glycogen and increase the blood sugar level. The acetyl sugars are put into the Krebs citric acid cycle and they are totally broken apart into carbon dioxide and a bunch of hydrogens are removed. The catabolism of a triglyceride will create 36 acetyl sugars at once and it will flood the system and they can’t go through the krebs cycle fast enough so some of these acetyl sugars become keto acids.
The process of removing that amino group is called deamination (taking away the amino group, NH2).
Anytime someone is forming increased amounts of ketoacids, you could smell the odor of acetone on their breathe, just like how you can smell when someone has been drinking alcohol. This article comes from Current Atherosclerosis Reports because reducing your fats is important for reducing your risk of atherosclerosis. Whether you’re fasting for religious reasons or you haven’t had anything to eat for a long time, what happens? Any knowledgeable clinician can smell that acetone on their patients breath.  It could be occurring because someone is fasting or it could be from diabetes too.
You’re supposed to be noticing things like alcohol or acetone on your patients breath. The keto acid levels become so high they spill over in the urine so now they are developing ketonuria. This is why a classic symptom of diabetes is frequent urination, because the ketoacids and sugars are constantly dragging water with them. The danger of diabetes is that if somebody needs to inject insulin and they don’t do it, three days later they may go into a coma and die because the increase in acid (decrease in pH level) causes the proteins to be denatured.
If all three macronutrients can eventually make ATP, and fat can yield more energy than glucose, why do we need glucose (or fructose) at all?? Energy production is essential for life, and the byproducts of fat metabolism are much worse on the body then sugar.
After increasing sugar a number of health conditions began to improve, and I began to take a look at metabolic impairments from SNP polymorphisms. But in regular ketosis induced by low carb intake, our body doesn’t overproduce ketones in non-diabetic individuals?

Your increased urine flow causes you to lose body sodium, which also stimulates your thirst receptors.
Because the cells are unable to use the glucose, they pull fuel from other sources-fat stores and muscle-and the diabetic person begins to lose weight. There should never be ketoacids in the urine, just like how there shouldn’t be sugars. I’m still beginning to comprehend all of this, but this article really cleared up for me why keto diets are all bad hormonally and metabolically.

When oxygen becomes available, lactic acid is converted back to pyruvic acid.  Remember that this all occurs in the cytoplasm. Then in your liver, this ammonia is turned into Urea which is basically a carbon and oxygen with two amino groups.
In fact most diets are now low carb or no-carb diets where they say you could eat all the protein you want.  You could eat all the fish, tuna, chicken and vegetables you want but have to dramatically reduce your intake of carbs. If somebody is unable to eat food, then this liver glycogen supply will be released into the blood stream because sugars are the favorite food source for the body to make ATP. GoGraph also offers EPS vector illustrations, clipart digital artwork, clip art, stock footage, and video animation clips.
Your liver releases this urea into the blood stream and is the major organic waste carried in our blood stream.
Toward the end of the 24 hour period, as the sugars are becoming more depleted, the breakdown of fats and to a lesser extent, proteins are beginning to make up for the energy loss. Sadly the government pushes high carb and low fat which just causes people to become diabetic. What happens is that this fatty acid is broken up two carbons at a time which turns it into the two-carbon acetyl sugar.
When they clinically measure the amount of urea in your blood, that is commonly known as the BUN level.
Reducing your carb intake is the key to getting rid of fat assuming you’re going to stay on the diet. The cells are starving for energy and as a result they are going to break down fats and proteins at a faster rate than normal because they can’t use sugar for energy.
Very hard to sustain (your body will CRAVE the carbs because it wants them for several reasons) and you need the MICROnutrients that come from the foods included as carbs (I.e. If I’m eating so little carbs, will my body take muscle tissue to use as fuel if I’m eating enough fat and protein? This blood is then filtered by our kidneys and appears in our urine as the major organic waste of our urine.
