Craig Emmerich, the husband of the queen of keto herself, Maria Emmerich, generously offers her guest ticket. Enjoy it!
When we eat macronutrients, our body goes first to treat them. This priority can be very helpful in understanding how our body works and how to exploit it to lose weight.
The body does not like to have any supersaturation of fuel in the blood at any time. It tightly manages fuels to avoid dangerous situations such as high blood sugar or too high blood sugar. But it also manages and controls other fuels such as ketones (beta-hydroxybutyrate or BHB) and fats (free fatty acids or FFA and triglycerides) in order to control them and not saturate the blood with fuel. .
It's like the engine of a car. You do not want to give the engine too much fuel and blow it up. So, the body controls the amount of fuel in the blood to make sure you do not explode. To do this, the body will first address the most important fuels (or potentially the most dangerous). This is done very logically – in the reverse order of storage capacity.
Here is a graph showing the distribution of oxidation priorities for food fuels.
Modified source: Keto. By Maria and Craig Emmerich
Original Source: Priority to oxidation, meal frequency and energy saving of food and activity: consequences for longevity, obesity and cardiometabolic diseases, Sinclair, Bremer et al, February 2017.
The first priority in the field of oxidation is alcohol because its storage capacity is zero. It makes sense for the body to take care of it first, because it can not be stored anywhere and too much blood alcohol means death.
The second highest priority for oxidation is exogenous ketones. These are ketone salts that increase BHB levels in the blood. There is also no ketone storage site, so the body must deal with it before using other fuels. This is why exogenous ketones are not the best option for losing weight. They displace the oxidation of fats, retaining stored fats, while exogenous ketones are used as fuel.
Protein is the third priority in oxidation. The protein is a little different because there is limited storage space for the protein, but the protein is not a good source of fuel. It takes 5 ATP to transform proteins into a fuel (glucose through gluconeogenesis) and 2 other ATPs to burn the mitochondria. Why would your body spend 7 ATP for something that it could do for 2 ATP simply by burning glucose or fat from your body? The protein is actually used as a fuel only when other fuels (glucose and fat) are not present and it is forced to use proteins. Proteins are mainly used to stimulate the synthesis of muscle proteins. He builds and repairs lean mass.
The next priority in oxidation is carbohydrates. It has a moderate storage capacity of 1,200 to 2,000 calories.
The last priority in oxidation is fat. This makes sense because there is theoretically unlimited storage capacity for fats. There are people with more than 400 kilograms of stored body fat, which represents 1.6 million calories.
The priority to oxidation can help you understand what happens when you put certain fuels in your body. If you consume alcohol while eating carbohydrates and fats, these will mostly be stored while your body is consuming high alcohol.
To understand the power of oxidative priority, take the case of an alcoholic. Alcoholics will have very low levels of A1c (within 4), no matter what they eat! If they eat tons of carbohydrates, they will always have an A1c in the 4's because the chronically high alcohol levels force the body to store all the glucose while dealing with alcohol. , thus creating a weak A1c. I do not recommend anyone to become an alcoholic to lower the level of A1c – but on the contrary.
So, what does this mean and how can you harness the biology of your body to lose weight?
If you avoid alcohol and exogenous ketones, get enough protein to support the maintenance of lean body mass (about 0.8 times your lean body mass in pounds per gram of protein per day ), limit the number of carbohydrates, then your body fat a little to force the body to use more stored body fat for you to lose body fat. When you limit carbohydrates long enough (4 to 6 weeks for most people), the body gets used to using fats as the main fuel (adapted to keto). This means that it can burn body fat as well as dietary fat. The elimination of other fuels and the maintenance of a moderate dietary fat level allow the body to focus on body fat, a source of fat loss.
This is our body's fuel processing system going into the diet. Use it to improve the results and body recomposition.

He has followed his wife Maria in the field of nutrition and has since devoted her time to research and the study of nutrition and biology from a systems perspective. Over the past 8 years, he has worked with hundreds of clients alongside Maria to help them heal their bodies and lose weight by using their biology to make their lives easier.
Thanks to Craig for his keto sighting today, and thanks to everyone who stopped here.
