There isn't a drug in the world that can undo the ravages of the lifestyle that leads to diabetes--but that won't stop Big Pharma from trying to sell you one anyway.

And they're really laying the sales pitch on thick right now, with researchers claiming that Actos can slash the risk of diabetes by 72 percent in prediabetics.

But as you'll see in a moment, there's a huge asterisk on that number.

Researchers gave 602 overweight and obese prediabetics either Actos or a placebo. Over an average follow-up of 2.4 years, just 2.1 percent of those who got the drug went on to develop diabetes--versus 7.6 percent of those who took the placebo, according to the study in the New England Journal of Medicine.

Now, think about this for a moment. In both groups, more than 92 percent of prediabetics *didn't* develop diabetes.

That tells us one of two things: Prediabetes isn't all it's cracked up to be as far as warning signs go... or 2.4 years is nothing in the deadly march towards diabetes.

I'll go with the latter, and that brings me to the asterisk: The study doesn't prove Actos can lower the risk of diabetes by 72 percent... all it proves is that it might slow the approach of the disease in prediabetics.

But that doesn't mean you'll avoid it.

Diabetes is not something you get in a day, a week, a month, a year or 2.4 years--it's something you work towards with years or even decades of poor eating habits and a sedentary lifestyle.

A drug won't fix that... and it might even make your life worse, because patients who took the drug in this company-funded study experienced some ugly side effects: average weight gain of nearly 9 pounds and a higher risk of dangerous and possibly deadly fluid buildups.

What's more, other studies have found that Actos may be almost as risky for the heart as Avandia, and some researchers have found a link between the drug and bladder cancer.

In other words, forget meds--and focus instead on fixing the problems that led to prediabetes in the first place.

And you start by skipping the sugar.

Tough, I know--but if you can shake your addiction to the sweet stuff and slash your overall carb intake, you won't just avoid diabetes.

You'll be the healthiest person you know.
