Eating collagen will not make you fat. Because collagen does not contain lipogenic factors such as sugar and fat, the collagen we often eat is usually extracted from fish and is more easily absorbed by the human body. Eating collagen not only won't make you fat, but also has a certain slimming effect. Because collagen can activate the activity of lipase and enhance the ability to decompose fat, in addition, the human body needs to consume a certain amount of energy while absorbing collagen, thus achieving the effect of slimming.

Extended data:

In fact, collagen exists widely in our daily food. Such as beef tendon, trotters, chicken wings, chicken skin, fish skin, corn, cartilage and so on. From the molecular point of view, collagen is a kind of biopolymer, which mainly exists in mammals, especially in animal connective tissue. Strictly speaking, it is the most important component of extracellular matrix. However, the collagen content of aquatic animals is higher than that of terrestrial animals, and the collagen content in fish skin can exceed 80% of the total protein.

Studies have shown that collagen contains essential trace elements for human body, and at the same time, it can reduce triglycerides and cholesterol in blood. Secondly, collagen in human bones can firmly lock the lost calcium. In addition, the application of collagen in beauty is also amazing. For example, collagen extracted from animal skin also contains proteoglycans such as hyaluronic acid and chondroitin sulfate, which contains a large number of polar groups and is a moisturizing factor, which can prevent tyrosine in skin from transforming into melanin, so collagen has natural moisturizing, whitening, anti-wrinkle and freckle-removing effects.
