On the internet, misinformation about carbs and keto is everywhere. One common suggestion is that toasting bread lowers its carbohydrate content, making it friendlier to low carb diets. But does this actually work? Is there any truth to it, or is it just wishful thinking?
-----------------------------------------------
Simply put, toasting does not do much to affect nutrients and macros in white bread, although there might be one advantage gained from toasting. Toasted white bread does have a slightly lower GI, and freezing bread before toasting reduces this further, giving the starches a more tempered effect on blood sugar and insulin production. As insulin suppresses ketone production, this makes toasted bread slightly better than untoasted white bread – but in the end, it doesn’t actually change your carb intake.
