What’s critical is not necessarily the cutoff itself, but where someone falls within the ranges listed above. The level of risk of developing type 2 diabetes is closely related to A1c or FPG at diagnosis. Those in the higher ranges (A1c closer to 6.4%, FPG closer to 125 mg/dl) are much more likely to progress to type 2 diabetes, whereas those at lower ranges (A1c closer to 5.7%, FPG closer to 100 mg/dl) are relatively more likely to revert back to normal glucose levels or stay within the prediabetes range. Age of diagnosis and the level of insulin production still occurring at diagnosis also impact the chances of reverting to normoglycemia (normal blood sugar levels).
Benari, an Ashkenazi Jew, doesn’t fall into that category. But Cummings and other bariatric experts I spoke to said that surgery should be a possible option for any person whose diabetes isn’t improving. Cummings himself is currently working on a clinical trial in India of bariatric patients with BMIs as low as 25. And he expects similar trials will come down the pipeline.
Is a prediabetes diagnosis serious? There has been significant debate around the term ‘prediabetes,’ and whether it should be considered cause for alarm. On the one hand, it serves as a risk factor for type 2 diabetes and a host of other complications, including heart disease, and ultimately prediabetes implies that a degree of metabolic problems have started to occur in the body. On the other hand, it places a diagnosis on many people who may never develop type 2 diabetes. Again, according to the CDC, 15-30% of those with prediabetes will develop type 2 diabetes within five years. However, a 2012 Lancet article cites 5-10% of those with prediabetes each year will also revert back to healthy blood sugars.

One easy way to increase your fat content and quit snacking is to begin your meal by eating an avocado. I and others I know have used this trick to easily quit snacking. Avocados protect you from one of the reasons some dietary research wrongly claims that high-fat diets are bad for you: the danger of gorging yourself on delicious, fatty foods. With plain avocados, there is little danger of gorging. Another danger is clogging your arteries and giving yourself heart disease. But it’s been amply shown that the blame for that falls squarely on trans fats, like margarine. If you see any product with the words “partially hydrogenated” or “hydrogenated” in the list of ingredients, put it back, it’s a trans fat. On the other hand, any fat that comes directly from an animal or plant is not a trans fat and can be safely consumed.
