Protein is low carb. Fiber is a carb that doesn't impact your blood glucose, because your body doesn't break it down. Thai food is heavy on noodles and rice, which are both very high carb.

Protein does have an effect for your glucose level. Just comes after a few hours as a nice surprise. And fat makes the insulin work worse, combine the fat with protein and it is quite complex to understand why your glucose is going up 3 hours after eating.

Oh, add some carbs to your protein and fat. Like a steak with creamy sauce and french fries. All the insulin you think is good is not enough.

Isn't this true of essentially most cuisines though, to be carb rich? Indian, Chinese, Mexican, Italian, French, etc - the typical diet in most places is heavily skewed towards carb in general. It's a matter of adjusting the ratio of protein-rich foods vs carbs within that cuisine to your needs.

Different carbs affect people differently, but for me rice was a big no no, whole wheat was OK, and corn was great (whew!).

So, Thai was pretty bad, Chinese not much better but you can find less sugary dishes. Indian was actually pretty good as long as I didn't gorge myself: The fat in the dishes helps slow down the sugar absorption so you don't get the extreme spikes, and you can pair it with a whole wheat roti instead of rice. Mexican was GREAT cause, corn + beans (beans were the best!! so much fiber and protein, barely any spike when eating them). Italian is ok as long as you make it yourself with whole wheat pasta and eat lots of meat and cheese. French is good cause they have lots of meat-focused dishes. The best meals for me were like a pork chop or steak, greens of some kind, and quinoa or whole wheat mac n cheese or polenta.

Lots of rice-centered dishes (rice has an especially high glycemic index), usually a ton of added sugar (pad thai, curries), sugar-based dipping sauces.
