For all my writing about kratom, the majority of the world still thinks that zero-calorie Red Bull and similar energy drinks are fine for diabetics. This is dangerous thinking and perhaps much of the reason these folks are diabetic.
We, in the USA, are fairly familiar -- at least in the more highly educated segment of the community -- that products are sold here by slapping the right words on the label. As in, putting the words "Energy Drink" on the label. You are supposed to assume that it will give you energy.
Savvy people know that the real question they need to ask is, "How does it give me energy -- what's the ingredient used?"
If you want to get free of diabetes, you need to think at a more discriminating level -- and act accordingly. Turning down Red Bull or Monster energy drinks, whether full-calorie or zero-cal, is the smart thing to do because both kinds raise your blood sugar levels, causing an insulin spike, with hunger to follow.
Our body is incredibly smart. It prepares to receive carbohydrates as soon as our taste buds perceive sweetness. When the stomach doesn't receive the expected calories, it sends a signal to the brain, telling it, "Go find me some calories, I'm hungry."
For those who aren't diabetic yet, drinking artificially-sweetened drinks increase our likelihood of becoming diabetic even more than sugar does. So, zero-calorie drinks are almost always made with artificial sweeteners and you need to avoid them. They do other bad things to your body, too, especially the sweetener Aspartame, aka Nutrasweet.
(The one exception to this is Stevia, a plant-derived no-cal sweetener.)
Believe me, I know the appeal of these drinks. I used to drink Diet Pepsi, when I really needed the energy and caffeine alone wasn't doing the job. It's a trap, though. Kratom tea is a much better option for diabetic-friendly energy, if it is available where you live.
