Nearly all Thai BBQ meat, fish and offal have sugar added by the marinade and sauces and as such are not keto friendly!
I do keto from time to time and only ever trust what I have purchased and cooked myself so I can calculate the exact carbs in each meal.....
It is time conusming to cook all your own meals from scratch, but you can easily make big batches of curry, chili, stews, soups, etc. and freeze them.
I use Pinterest or just Google keto recipes....You won't have any trouble finding loads of great recipes!
Good luck!
