I agree with this.
On multiple occasions now I've tried cutting out ALL starch and getting my carbs from milk, fruits and honey for several months at a time. One of the worst symptoms I used to have was feeling poisoned/sick (especially in the morning), which I assumed to be endotoxin-driven, hence why I cut out the starch. My experience with zero starch is that it made me feel a bit better in the short-term, but in the long-term it made my situation way worse; more endotoxin issues, weaker digestion, poor immunity, skin infections, feeling cold, low sex drive, dandruff, and the list goes on. Perhaps because all the cold/damp foods like milk and juice and honey was killing my already weak digestive fire and allowing pathogenic bacteria and fungus to set up shop?
The only problem was that I couldn't go back to eating starches again without feeling really sick. It's taken me AGES to be able to eat some damn rice or oatmeal without feeling like crap, but after a lot of tweaks I can now digest starchy carbs again and I really feel 10000% better than on a zero starch diet. No endotoxin symptoms at all and I wake up feeling normal, not like a truck ran over me a hundred times.
For me I think the main problem was a sluggish gallbladder → no bile acids to detoxify endotoxin and gut dysbiosis.
