The belief that one must consume huge amounts of food in order to be adequately nourished naturally is incorrect. See http://sankey.ws/dietpills.html for some specific examples with real numbers attached.
It is *possible* to obtain the recommended daily intake (RDI) of all USDA-quantified nutrients with as little as 1000 calories/day of natural foods (though I admit I wouldn't stick to that narrow a diet for long!) And remember that the RDIs used for the calculations on that page are roughly double the real requirement of healthy people, to give wiggle room for those with minor health problems.
It is easy to be naturally well nourished on 2000 calories/day - lots of food choices. It just depends on what you eat. It's also easy to overdose with artificially-concentrated supplements, dangerously so with most fat-soluble nutrients.

Then why even bring the subject up? Just Trolling?
I recall a study that said that you could meet your daily RDAs on about $1.65 a day. But, to do so, you had to eat total garbage in my humble opinion. Living on such a diet in the long term would shorten your lifespan, IMHO.
And, I don't mind saying that making comments such as yours is just plain STUPID!
