Monosaccharide, disaccharide, oligosaccharide and polysaccharide, which is more suitable for losing weight? What kind of sugar metabolizes fastest in the body and does not accumulate into fat?

Disaccharide will hydrolyze, but it will become two monosaccharide molecules after hydrolysis.

Polysaccharides are different from the above two. Polysaccharide is not sweet, but the above two are sweet.

So if you lose weight, you usually eat polysaccharide, because polysaccharide can maintain the sugar needed by the body, but it is insoluble and excreted directly. For example, cereals are rich in polysaccharides.
