Thanks for pointing it out! Unfortunately, I couldn't find a link to the study that they refer to. There are a couple of studies and it seems like not eating too much is "save". Like not eating too much salt or sugar.

I'm still waiting for the study that shows that any amount of erythrol is bad for you. There's no study that showed that eating a cake now and then with erythrol is bad for you. I mean, neither is sugar, but in a cut it limits your calorie intake
