Is the bulletproof diet actually healthy

The Bulletproof Diet Review: Does It Work For Weight Loss?

  • Note that the bulletproof diet has several drawbacks.

  • The Bulletproof Diet is believed to be based on solid science, but the results on which it relies are of poor quality and inapplicable to most people.

  • For example, Asprey cites sloppy data claiming that cereal grains contribute to nutrient deficiencies and that the fiber in brown rice prevents protein digestion (17).

  • However, cereal grains are often fortified with many important nutrients, and their consumption increases, not decreases, your intake of important nutrients (18).

  • And although fiber from plant-based foods such as rice is known to reduce the digestibility of some nutrients, the effect is rather small and harmless as long as you eat a balanced diet (19).

  • Asprey also offers simplified diet and human physiology views that suggest people shouldn't consume fruit regularly because it contains sugar or all dairy products - except ghee - promote inflammation and disease.]

  • In fact, eating fruits has been linked to weight loss, and dairy products have been shown to be anti-inflammatory (20, 21, 22).

  • The bulletproof diet can get expensive.

  • Asprey recommends organic products and grass-fed meats as these are more nutritious and contain less pesticide residue than their traditional counterparts.

  • However, because these items are much more expensive than their traditional parts, not everyone may be able to afford them.

  • Although organically grown products tend to have fewer pesticide residues and possibly higher levels of certain minerals and antioxidants than conventionally grown products, the differences are likely to be insignificant in terms of actual health benefits (23, 24), 25, 26).

  • The diet also recommends frozen or fresh vegetables over the often cheaper and more convenient canned vegetables, although there are no real health benefits (27).

  • The bulletproof line of branded products make this diet even more expensive.

  • Many of the items in Asprey's food line that are classified as bulletproof are its own branded products.

  • It is highly doubtful that any person or company would claim that buying their expensive products would make their diet more successful (28).

  • Asprey's constant categorization of food as "toxic" or "bulletproof" can lead people to have unhealthy relationships with food.

  • Consequently, this can lead to an unhealthy obsession with eating so-called healthy foods called orthorexia nervosa.

  • One study found that a strict all-or-nothing approach to dieting is linked to overeating and weight gain (29).

  • Another study found that strict dieting was linked to symptoms of an eating disorder and anxiety (30).
