Dangers of Zero-Carb Diets, I: Can There Be a Carbohydrate Deficiency?
Dangers of Zero-Carb Diets, II: Mucus Deficiency and Gastrointestinal Cancers
Danger of Zero-Carb Diets III: Scurvy
Dangers of Zero-Carb Diets, IV: Kidney Stones
All very interesting and challenging.
Here is another possible concern:
High-protein, reduced-carbohydrate weight-loss diets promote metabolite profiles likely to be detrimental to colonic health.
Another possible mechanism: the loss of beneficial compounds produced by gut flora feeding on plant foods.
With less fiber in the diet, there is less butyrate production - butyrate is beneficial. Apparently the high-protein low-carb low-fiber diet causes gut flora to shift to protein metabolism which causes release of toxic nitrogen compounds. Overall gut flora may become more pathogenic, less commensal.
In the last few months I have started eating more carbs. Sweet potatoes, potatoes and some tapioca. NO WHEAT, no beer, no bread. I have started to feel better - the grain free bit has sorted out my IBS - and am getting leaner.
Interesting that Kurt is also having more carbs recently.
