There is no RationalWiki without you. We are a small non-profit with no staff — we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.
If everyone seeing this today donates $5, we will meet our goal for 2018.

The bulletproof diet is a modified version of the "Paleo" diet created by web-marketer and blogger Dave Asprey.
Selective Use of Data
Often the journals used by Asprey to justify his claims are heavily misinterpreted (for example, unequivocally recommending those following the Bulletproof diet eat white rice over brown rice because, beriberi be damned, according to one study white rice is a whole ~2% better at nutrient absorption). In some cases, the recommendations are outright rubbish, e.g. opposition to the consumption of sucralose and the recommendation of raw milk consumption.
The diet's unique selling point is that it promotes massive consumption of stimulants, specifically caffeine and modafinil. The Bulletproof Exec website recommends that breakfast be replaced by a large amount of 'Bulletproof Upgraded Coffee', a product sold by Asprey, mixed with a spoonful of 'Bulletproof Upgraded MCT Oil', a coconut-oil derivative also exclusively sold by Asprey's company which he claims will deliver 'fast energy' to buyers.
The diet's website goes on to claim to its followers that the majority of people are "Suffering from a Modafinil Deficiency", This is complete and
udder utter bullshit since Modanifil is a synthetic drug. Asprey claims to having been on a 300mg daily dose of the stimulant for the past 9 years (together with use of synthetic hormones — 'testosterone replacement therapy').
