I asked about the safety of diabetics on low calorie diets. I have no idea how stringent the entry criteria was for this study, they could have picked the [otherwise] healthiest diabetics they could find.
Which brings us back to the question I asked, which was how this could scale to older or in worse health individuals suffering from type 2 diabetes? Even with medical supervision.
It would only be a problem if you took insulin and then did not eat. Given that type two diabetics cell’s are stuffed full of sugar from insulin resitance, not eating or eating less can only help.
