http://www.ncbi.nlm..../pubmed/6368151 That study says: "The observed increase in insulin in the early morning hours despite stable levels of glucose indicates a temporally increased insulin need in nondiabetic individuals similar to that found in individuals with diabetes."
Here's another one: http://www.ncbi.nlm..../pubmed/6389230 "These results indicate that a dawn-like phenomenon, initiated by an increase in glucose production, occurs in nondiabetic individuals."
But there are studies that say the opposite: http://www.ncbi.nlm..../pubmed/3514653, http://www.ncbi.nlm..../pubmed/2646356. These studies referred to the subjects as "normal" or "healthy". I think people with acne do not fall in the "normal" category. Though we are not diabetic, we might still have problems with insulin.
Here's a few more non-credible sources that say everyone experiences the dawn phenomenon:
I'm not claiming that everyone experiences this, but I think it is possible, especially with people with acne and blood sugar problems, that we experience this effect. The articles above said that a way to stop the effect is to avoid eating late at night, and make sure we eat breakfast. To prevent the dawn phenomenon, we can avoid carbs at dinnertime, and to not make it worse, we can avoid carbs for breakfast. Instead of carbs, we should eat more healthy fat and protein. For people already eating low glycemic load meals, this shouldn't be a problem.
So this just provides another reason to eat low glycemic load meals, limit carbs and eat more fat and protein.
