Just even in the last 5-10 years, there have been quite a few discoveries in human biology and physiology which turned former wisdom on its head. Some systems which were previously unknown or misunderstood altogether have had major revelations (e.g. - glucose transporters in the regulation of energy within the body). As a product, certain conditions whose progression was once accepted as unavoidable or determined turned out to be quite the contrary. Type II diabetes is among them. Recently, there are several studies challenging the conventional narrative on diabetes, one of which I just this last month shared: http://www.elev8wellness.com/wellblog_best_nutrition_training_coaching_experts/cure-diabetes-in-short-order.
Several years ago I was already trying to encourage people to take this understanding into their own hands: http://www.elev8wellness.com/wellblog_best_nutrition_training_coaching_experts/lose-15lbs-for-15-in-2015. It's actually a very straight-forward and simple set of behaviors to prevent, stop the progression toward, or reverse already-existing diabetes. And the number of stories of people who've pulled it off is ever-growing.
Prior to that, however, there was already conclusive evidence that one could reverse diabetes: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3168743/. And I might add that wholly absent in the discussion about reversal of diabetes is any mention of drug therapy.
Not to be confused with type I Diabetes, type II is a daily progression toward or away from harm to receptors. Although there is some evidence advances in immunology and organ transplant are going to change our views about type I as well, what I'm talking about here is the very common and ever-evolving systemic regulation of energy within everyone.
It's not really an issue which has different perspectives or has been up for debate for about a decade. It's simply a matter of compliance and patient willingness. All of us are on a spectrum moving toward or away from diabetes (glucose intolerance and insulin resistance). Regardless of your diagnosis, you are either moving toward or away. None of us enjoy a fixed status as "not diabetic" OR "diabetic." It is continuously in flux, within the year, the month, the week, the day, the hour, the minute.
The research is clear. The mechanisms are known. Deplete stored energy in the body and you will restore youthful control of blood sugar and insulin. Fast. Exercise. Restrict intake. Do something to deplete stored energy. That will stop or reverse the trend toward or into diabetes. Anything else is moving us toward it.
