First of all, the methods of protein extraction and protein separation and screening are not mentioned, which shows that there are obvious technical defects, because similar heterogeneous health foods or simple foods will claim to adopt the international advanced supercritical extraction technology, concentration technology or nanotechnology (in fact, it is not advanced or useless at all). There is no such boast here, which shows the psychology of manufacturers.

Moreover, from the pharmaceutical point of view, the extraction of protein components is very particular. First of all, most of the active proteins have relatively small molecular weights and are not resistant to heat. If traditional hot water extraction or high concentration ethanol precipitation is used, some of them will be inactivated. From the separation point of view, conventional extraction methods will extract sugar together. How to separate monosaccharides, disaccharides, oligosaccharides and polysaccharides is a very troublesome thing. According to the normal propaganda mode of health food, it is impossible for this difficult technology not to exaggerate. Besides, how to isolate and obtain what he called "OB protein slimming factor" from various protein will be an extremely difficult technology. If the so-called "OB protein slimming factor" monomer can really be isolated, and the weight loss effect is outstanding and the toxicity is low, then the developer has made great efforts. Why not develop it into a new drug? You should know what a new drug means, and no one is stupid. Nobody needs to comment on the fishy things here. His so-called factor, element, is a selling point, but it is likely that another chemical composition really works. Because chemicals do have an immediate weight loss effect, they are not widely used because of their toxicity. Under the cover of this pile of concepts, adding obvious ingredients is really a good way to make money.
