Fat soy sauce?

The short answer is - yes, soy meal can also be fattening!

Anything that is added extra, of protein, fat and carbohydrate, that the body does not immediately need, is theoretically fattening. When that happens, the body converts it and stores it as fat for worse times, because “the body is smart” and has been for many, many millions of years. But if we ignore the fact that we are overfeeding the horse, soy meal is an incredibly good and strong quality source of protein.
Soybean meal is a highly concentrated source of protein, which the horse needs to maintain its muscle mass during weight loss.
When the horse needs to lose weight, the amount of roughage/wrap is reduced because we want to reduce calorie intake. However, when we reduce the amount of wrap, the amount of protein supplied is also reduced, which often leads to protein deficiency. If the horse does not get enough protein, it begins to break down its own muscles to get the vital proteins and amino acids from elsewhere in the body.
The body is extremely competent at prioritizing. This means that when protein is needed in other and more vital places in the body, the horse has to use up its muscle mass because there is a “storehouse” and protein must first and foremost be produced for other, more vital functions.

Protein is included in, for example:

• Enzymes: Enzymes are proteins that act as catalysts in biochemical reactions that are essential for metabolism.
• Hormones: Many hormones, such as insulin, are proteins that regulate physiological processes and help maintain homeostasis.
• Antibodies: The immune system's antibodies are proteins that help protect the body from infections by identifying and neutralizing foreign substances such as bacteria and viruses.
• Transport proteins: Proteins such as hemoglobin in the blood transport oxygen from the lungs to the rest of the body. Other transport proteins in cell membranes help move substances in and out of cells.
• Structural proteins: Collagen is an example of a structural protein found in skin, connective tissue, tendons, ligaments, bones, and hooves, providing strength and elasticity.
• Receptor proteins: These proteins are found on cell surfaces and receive signals from the environment, which help the cell respond to various stimuli.
• Plasma proteins: Albumin and globulins in blood plasma help maintain the osmotic pressure of the blood and transport lipids, hormones, and vitamins.

Proteins are therefore central components of many of the body's systems and processes, making them essential for maintaining life and healthy functioning of the body.

So there is enough for the body to make sure it can send protein supplies out. Too low a protein intake will cause muscle loss and thus a lower metabolism, which puts the horse in a situation where it easily gains weight again when the weight loss is complete, because it now has a lower basal calorie consumption.
However, if we ensure that the horse meets its protein needs daily through supplements such as soy meal, it can maintain its muscle mass and thus its vitality and health. Good muscle mass and optimal protein supply ensure that all vital processes in the body function optimally, and the horse can lose weight by burning fat instead of muscle mass. In this way, the horse achieves healthier and more sustainable weight loss, because the goal is always health.
