How to Prevent Prediabetes from Turning into Diabetes


Approximately 1 in 3 Americans have prediabetes, but only about 1 in 10 knows it. What works better at preventing it from turning into full-blown diabetes—drugs or diet and exercise?

I often hear the diet and exercise intervention described as 60% effective. That’s still nearly twice as effective as the drug, but that other study really showed it may be more like 100% in people who actually do it. So is diet and exercise 100% effective or only 60% effective? On a population scale, since so many people won’t actually do it, it may only be 60% effective. But on an individual level, if you want to know what are the chances you won’t get diabetes if you change your lifestyle, then the 100% answer is more accurate. Lifestyle interventions only work when we do them. Kale is only healthy if it actually gets into our mouth. It’s not healthy just sitting on the shelf.
