Hydrogel-based expanding pill for weight loss shows promising results in trial

I take psyllium husk pills in the morning for some additional fiber intake and better stool passing, and I haven't felt much need for breakfast. I wonder if I'm conditioned to not feel hungry early in the morning, or the pills have some satiation effects similar to the hydrogel here.

I wonder how this pill compares to the already quite cheap psyllium husk, and what it does to the stool.

Gelesis100, another oral hydrogel, I understand is not very effective, I wonder what makes this one different?
