It appears the author avoids the simple solution of bringing more monosaturated oils into the diet. If raw vegetarianism forbids it, then it is likely a failed diet plan. Leaning more and more towards "keto vegetarian", I consume more olive oil to get those calories, and I am loosing weight still. Eating raw walnuts is supposed to be one of the highest sources of alpha linolenic acid, however upon visual analysis of stools you can see a large amount of walnut remains passing through without much apparent digestion.

On the other hand, the strict keto dieters are eating meat which has excessive cholesterol, artery clogging saturated fats and red meat has high loadings of free iron (toxic).
