Q10 and chromium for stable blood sugar and efficient fat metabolism

The production of cellular energy takes place in the mitochondria, where Q10 plays a key role in the metabolism of the two primary fuels: carbohydrates and fats, which are broken down into blood sugar and fatty acids. In addition, cellular uptake of blood sugar requires chromium, and mitochondrial uptake of fatty acids requires a substance called carnitine. Meat and other animal products naturally contain carnitine and therefore support efficient fat metabolism. The body can also produce small amounts of carnitine, a process that requires vitamin C.
You can also read about a Danish-Norwegian study that revealed how mice must consume six times more calories to gain one gram of body weight when fats are combined with a high protein intake. By contrast, fats combined with carbohydrates result in poor energy utilization, with a risk of excess fat storage and increasing overweight.

We all need plenty of energy and stable blood sugar levels for the brain and body to function normally. After we eat or drink, energy-yielding nutrients are transported through the bloodstream to the various organs and tissues. All cells contain small bean-shaped power plants called mitochondria, where nutrients are converted into energy. Carbohydrates and fats serve as the primary fuels, also known as macronutrients. Q10, along with a range of vitamins, minerals, and carnitine, is also required for cells to absorb and metabolize these calories. Energy metabolism and weight regulation therefore depend less on total calorie intake and more on how efficiently calories are burned.

Q10’s key role in mitochondrial energy metabolism

The metabolism of carbohydrates, fats, and protein takes place in the inner membrane of the mitochondria, which resembles a series of folded structures. Here, nutrients are metabolized with the help of the oxygen we breathe and a variety of vitamins and minerals that participate in different enzyme processes. In addition, coenzyme Q10 plays a unique and essential role in the mitochondria’s so-called electron transport chain. Q10 receives and transfers electrons, enabling energy to become increasingly concentrated. Initially, this process generates chemically stored energy in a molecule called ATP (adenosine triphosphate). With further assistance from Q10, the mitochondria can then split ATP and release the energy needed for activities such as thinking, breathing, muscle function, antibody production, hormone synthesis, and cellular renewal.
Without Q10, we would quickly die, which is why the body produces most of its own supply. However, endogenous production gradually declines with age, and many people notice this as decreasing vitality after the age of 40–50. Cholesterol-lowering drugs (statins), osteoporosis medication (alendronate), and certain mitochondrial disorders can also inhibit the body’s production of Q10. Fortunately, it is possible to compensate for reduced endogenous production with a high-quality, well-documented Q10 supplement if additional energy support is desired.

Carbohydrate metabolism requires insulin and chromium

Carbohydrates are found in grains, flour, potatoes, rice, corn, fruit, sugar, and many other foods. During digestion, carbohydrates are broken down into glucose (blood sugar), which is absorbed from the small intestine. This causes blood sugar levels to rise, prompting the pancreas to produce the hormone insulin.
Chromium is also required because it is part of a molecule called chromodulin, which binds to insulin receptors on the cell surface. This is crucial for insulin to function optimally as a key that unlocks the cells’ ability to absorb glucose. Inside the cell’s cytosol, glucose is then broken down into pyruvate, which is transported into the mitochondria for energy production.
However, if chromium is lacking, cells absorb and metabolize carbohydrates less efficiently. This automatically leads to fatigue and untimely hunger, creating cravings for sugar, cakes, chips, and other refined carbohydrates that rapidly enter the bloodstream.
Unstable blood sugar can quickly become a vicious cycle in which cells gradually develop insulin resistance, resulting in a chronically reduced ability to absorb blood sugar. Over time, unstable blood sugar and insulin resistance may develop into metabolic syndrome and type 2 diabetes, both of which are spreading at epidemic rates.
Stable blood sugar therefore requires chromium, which is found in foods such as brewer’s yeast, almonds, seeds, beans, fish, shellfish, and meat. When it comes to supplements, chromium-enriched yeast provides the best absorption. It is also important to focus more on complex carbohydrates such as whole grains and vegetables while avoiding or limiting refined carbohydrates such as white flour, white sugar, dried fruit, fruit juice, and highly ultra-processed foods. It is also beneficial to include sufficient protein and healthy fats with every main meal.

Efficient fat metabolism requires carnitine and vitamin C

There is no reason to fear fat, as wholesome, unprocessed fats from animal foods as well as avocados, nuts, seeds, olive oil, and coconut oil are excellent sources of energy—especially for the heart and muscles. Since fat metabolism requires a considerable amount of oxygen, it is most efficient during physical activity that does not leave you out of breath.
Dietary fats circulate in the bloodstream as fatty acids, and their uptake into cells and subsequently into the mitochondria requires carnitine (L-carnitine), which acts as a transport molecule.
Carnitine is naturally present in high concentrations in animal foods, especially red meat such as beef and lamb. In fact, the name carnitine is derived from the Latin word carnis, meaning meat. As a result, plant-based diets do not provide carnitine, which is one reason why many vegetarians and vegans choose to take supplements.
However, the body can produce small amounts of carnitine in the liver, kidneys, and brain through a multi-step process involving the amino acids lysine and methionine. Adequate vitamin C is also required, as it helps optimize the body’s production of carnitine and supports energy metabolism.

More reasons to include animal proteins for fat metabolism and weight regulation

As already mentioned, animal foods contain the transport molecule carnitine, which is essential for cellular uptake of fatty acids and efficient fat metabolism.
There is also evidence that proteins activate the body’s brown fat cells, which do not store energy but instead burn fat to generate heat. This was demonstrated in earlier groundbreaking research conducted by the University of Copenhagen and the Norwegian NIFES (National Institute of Nutrition and Seafood Research).
The study was carried out in mice that were fed either oil combined with carbohydrates or oil combined with protein. Although the mice consumed the same number of calories, the study revealed that mice had to eat six times more calories to gain one gram of body weight when oil was combined with a high protein intake rather than with carbohydrates. The effect was particularly pronounced when the protein came from fish but not from milk. This is probably because milk proteins contain more growth-promoting substances (including casein), whose primary biological purpose is to help offspring grow rapidly and gain weight.

• Fat metabolism and weight regulation depend less on calorie intake and more on the balance between protein, carbohydrates, and fat
• The most fattening dietary pattern is generally a combination of carbohydrates and fats, as found in foods such as pizza, French fries, chips, cakes, and many industrially processed foods. In addition, modern plant-based diets often contain too little protein
• Proteins from animal sources such as meat, fish, and eggs support particularly efficient fat metabolism because of their carnitine (L-carnitine) content and because they appear to increase fat burning in brown, heat-producing fat cells
• The quality of the raw ingredients also matters.
