First things first, most folks don't have access to a lot of fine coffee simply because of the cost barrier. Really, you have to work with the stuff that is more often available to people - and for most, that is grocery store coffees of different sorts. The only 'cafe' I had access to with any regularity was Starbucks in the US, and that hardly counts. Small-to-medium sized Indiana towns aren't exactly known for their coffee selection, and really, if the advice can't be used by a good chunk of the population, it isn't going to help much with cutting calories from daily drinks.

I know there are tea-like coffees. I don't like them: I get introduced to new stuff in December, when I order a coffee bean Advent calendar from a little Norwegian brewer: I kinda hate the days of the fruity, tea-ish coffees. Even if they were my favorite, I can't afford to drink this daily.

But that's besides the point. Cream, especially, gives a completely different mouthfeel. When I did put cream in coffee, I would have done it with the fancy coffees as well, though you could talk me into taking a sip otherwise.
