If this was the only writeup Roberts ever produced, the cringing would be well deserved. However, he does have a long history of correctly quantifying changes in himself and identifying their source.
Specifically, his (on its face, ridiculous) shangri-la diet works well for 80% of the people -- probably better than any other diet (Although it should be noted that about 20% of people who try report it does not work at all).
Also, his flax seed, butter and vitamin D results have been replicated consistently by many (though again, not all). You can wait 15 years until these things get verified/shown wrong, or just try them yourself.
And about "well founded" - it's easy to dismiss some guy on the internet (regardless of his track record and academic qualifications, as this particular writeup was not done in the context of these qualifications). But you should be aware of your confirmation bias - e.g., if you ever considered any of the examples I give here http://news.ycombinator.com/item?id=4427910 well founded.
