I'm considering a set of stainless steel cookware from either AllClad or [Inoxia](https://www.inoxia.it/en/technical-area/)

Both cookwares are made of 18/10 stainless steel but Inoxia states you can cook fat free in their cookware:

> 
> During the use of the cooking unit the heat accumulates in the
>  high-thickness structure of the capsular base, which spreads it back
>  gradually and uniformly inside the pot, so that foods can be cooked
>  without water or fats addition.
> 
>

Is this true for AllClad? (or any cookware made of 18/10 stainless steel with 5-ply construction?) Otherwise what is the technical feature allowing for the water/fat free cooking in Inoxia?
