It is very difficult to eat out in Thailand without getting some sugar. Thai's love sweet stuff.
I have cut way back on eating rice, bread, potatoes, sugar, etc.. (also do intermittent fasting). I wouldn't say I am on a strict Keto diet. Before I was taking 1000Mg of metformim a day and my A1C was around 6.2 to 6.5. After a couple of months on the new diet and stopping all my medications my A1C is now 5.4.
