A common belief among people is that carbohydrates are “necessary” for physical exertion and any form of athletic activity. To test this hypothesis I did a VO2 max test before and after my final dietary intervention – ketosis. During this test, a number of other physiologic parameters are measured: heart rate, power output, and lactic acid levels in the blood (hence, the blood stained towel in the picture below hanging over the handlebars from the constant finger sticks to get blood). So how did my performance change over the final 12 weeks of my nutritional experiment, when I was in a state of ketosis?  The table below summarizes my findings, but let me add a bit of commentary. Prior to ketosis – At this level of energy output, I required 95% of my energy to come from glycogen, and was only able to get 5% of my energy from fat. Post ketosis – At this same level of energy output, I was now only 22% dependent on glycogen, and therefore able to get nearly 80% of my energy from fat. The real question is how can you get the best of both worlds?  That is, is there a way to reap the benefits of keto-adaptation of on the aerobic side, without any of the anaerobic cap costs?
In short, I believe the answer is yes, and I look forward to writing about this in great detail in the near future.
This short and simple post is part of a sequence of posts that are on the low-carbohydrate ketogenic lifestyle. Ketosis (often called nutritional ketosis) is the metabolic state where you body uses fat to create energy. Now, to reach ketosis (thus use fat for energy) one has to either fast or restrict carbohydrates. When your body does not have the carbohydrates necessary to convert them to glucose which will be used for energy, it shifts to the second way to create energy, by breaking down fat. When you give your body less than 50g of carbohydrates (some people need to have less than 30g, others need to have less than 20g – it depends), it will start breaking down fat into the liver and create ketone bodies.
It should not be confused with ketoacidosis which is often a Type 1 Diabetes condition where people have 10-15 times elevated serum ketones compared to nutritional ketosis, simultaneously with elevated blood glucose levels. In nutritional ketosis, blood glucose levels as well as insulin remain fairly low while ketones are elevated. So, when you’re restricting carbohydrates as mentioned above, you make your body use fat for energy.
In some of the follow up posts I’ll talk about the foods that you can eat to be in ketosis and the ones that you should avoid.

The final nail in the coffin that made me abandon the keto-path was the emergence of food cravings.
Keto-adaptation is not suitable for me, as my training entails quite a bit of interval training. By the end of my keto-adapted state I got more pronounced feel for my body’s hunger signals. Thirst is more pronounced in keto-state, at least for me, as I was drinking at least 1 l of water more per day as usually.
I certainly clung to that belief for the majority of my life, especially as someone focused on endurance sports.
There is no shortage of places to read about this test, but I’ve included a figure, below, showing you what it looks like, and what it measures.


Let me start with the one folks are probably least familiar with – the respiratory quotient. Ketosis is an important term and it needs to be fairly understood by those who follow this type of lifestyle (in terms of nutrition). It can also be created by your body, in certain conditions and certain systems of the body.
Bonking is the point of exhaustion when you don’t have the energy and the motivation to go further. These ketone bodies are the by product of fat oxidation and they are: acetone, aceto-acetate, and beta-hidroxybutirate (BHB). During prolonged fasting, insulin and blood glucose levels may further decrease (but never become inexistent) while ketones can further increase but mostly never reach dangerous levels.
You practically use both the fat that you eat and also the fat that you have in your body storage.
I mean, food and shelter are two of the most important human needs (according to Maslow’s hierarchy), so why not make your life better? This keto adaptation approach entails severely limiting your carbohydrate intake, usually to less than 50g per day, in order to teach your body metabolism to burn and use exclusively fat for fuel, i.e. The theory behind keto-adaptation seemed plausible and very compelling, therefore decision was unambiguous: bring on even more fat! For me to achieve this, I needed to cut my carbs to less than 50g per day and limiting protein intake to fewer than 140 g (less than 2g per kg of body weight). Like before I couldn’t produce maximal efforts in interval training, tempo and long workouts were at lower intensities and most importantly, realization of my training plan came into jeopardy as a consequence of low motivation. As my well-being got progressively worse I increased my fat intake even more, now eating in excess of 500g per day, thinking my body needs more energy. Even though I was eating more than enough in terms of calories, my body was still craving for carbs due to training demands, something that I falsely ascribed to lack of calories in the first place.
By that time I learned, that one of the insulin effects on the body is the retention of fluids. Even though I consciously knew that fat is not harmful, I was still having subconscious doubts when searching for highest fat products in the store. However, at least theoretically, it seemed possible that I should be able to get by utilizing far more fat than glycogen for aerobic activity, if I could only figure out how. Parenthetically, this test is only slightly more pleasant than a root canal without anesthetic (I’ve had this done once), as you are forced to exert yourself to the point of complete failure.

My problem, my body is used to burning carbs, and even after 3 months I still get cravings. But most striking difference from a couple of weeks before was now even more pronounced lack of motivation to start movements.
I was frequently making self-excuses for missing workouts here and there and this was totally against my previous habits. Total consumed calories went over the roof, but I was having food cravings, almost like the ones before starting LC. Typically, it’s either done with you running on a treadmill or riding your bike on a stationary trainer, as I’m doing below.
My body measurements and the DXA scans that I did before and after the experiment showed that I lost 4.2kg (~10 pounds) of fat during this time.


I have continual problem with fatigue as my adrenal function is little to none, so I have no hormones of any kind. Not only lack of motivation to start training, but a really strong aversion to start any kind of movements, i.e.
You wear a mask that excludes any inflow or outflow of air from your nose and a pair of sensors measure the exact concentration of oxygen and carbon dioxide leaving and entering your mouth. Misinterpreting this signals and ingesting even more fat resulted in gaining some weight back.
From this, a computer calculates VO2, the minute volume of oxygen – that is, the actual volume of oxygen your body is processing. Has placed me on 30 mg of cortef a day, which converts into cortisol which provides me with some energy.
I need to lose an additional 15 pounds to be at 135 which is good for my 5 ft 8 inch height. And I was feeling cold non-stop, at home and at the office, I was freezing in pool so much that I couldn’t complete sessions. As a general rule, every 1,000 mL of oxygen processed requires about 5 calories of energy expenditure. And as I was going through various literature searching for answers, it become more and more clear to me, that I was starving (lack of motivation, difficulties in starting movements, lower body temperature, depression…). But due to previous experiences of “constant” hunger when on HC diet, this hunger sensation was quite natural to me.
Once glucose enters the cells, a series of metabolic reactions break it down into carbon dioxide and water, releasing energy in the process.The body has an ability to store excess glucose in the form of glycogen. Glycogen consists of long chains of glucose molecules and is primarily found in the liver and skeletal muscle. When fat and carbohydrate metabolism is in balance, most acetyl CoA enters the so-called citric acid cycle (Krebs cycle) where it is used for energy production. When acetyl CoA cannot enter the citric acid cycle, it is shunted to form ketone bodies.
Acetone can sometimes be smelled from the breaths of people with high levels of ketone bodies in the blood. You may be acquainted with the smell because some nail polish removers contain acetone.Ketone bodies are not only produced when the glycogen stores become depleted. Research indicates that the heart and kidneys prefer to use ketone bodies rather than glucose as a fuel resource. To dispose of excess ketone bodies, the body uses the kidneys to excrete them in urine, and they are exhaled from the lungs.
During ketosis, ketones can easily be detected in the urine.Nutritional KetosisWhen daily carbohydrate consumption is restricted to below 60 grams per day, the body usually shifts into ketosis and blood levels of ketone bodies start to rise.
While the standard American diet contains 45-65% of calories from carbohydrate, ketogenic diets usually restrict carbohydrate intake to about 2-4% of calories. In the 1920’s ketogenic diets were popular due to their efficacy in childhood epilepsy.
Fasting and carbohydrate restriction leading to ketosis can cause headache, nausea, fatigue, dry mouth, bad breath, upset stomach, nausea, frequent urination, and lack of mental clarity.The symptoms associated with ketosis are most often temporary and will usually pass in a couple of days.
