Despite what you've heard, type-2 diabetes doesn't have to be a lifelong sentence.

You don't have to live with the disease or even "manage" it. It can be cured -- and I mean really, truly cured: No more drugs, and no more insulin.

But there's one supposed cure that I definitely don't recommend, and that's the dangerous stomach-shrinking surgeries making headlines lately.

Sure, those procedures can take the weight off fast. And in two new studies, the results were so good that surgery is now being touted as a cure for the disease.

In one, gastric bypass surgery brought blood-sugar levels down to normal in nearly half the diabetics who had it. In the other, 95 percent of diabetics who had biliopancreatic diversion surgery were in remission within a year, along with 75 percent of those who got the Roux-en-Y procedure.

Some patients in both studies were able to stop meds before they even left the hospital -- and when you consider that diabetes drugs include some of the worst of the worst (Avandia, anyone?), I'm all for that.

But a dangerous surgery isn't what I'd call the best alternative to drugs. Sure, it might lead to quick results -- but this is one case where you don't want to take any short cuts.

That's because bariatric procedures don't cure the biggest diabetes risk factor of all, and that's the poor eating habits and sedentary lifestyle that caused the disease in the first place.

Just look at singer Carnie Wilson. She's not a diabetic -- not as far as I know, anyway -- but she recently made headlines for having a second Lap-Band surgery after the weight she lost from her first one came back.

"I reverted back to old habits (like) mindless eating," she recently confessed in an interview. As a result, she went from 150 pounds after her last surgery... to 236 pounds before her second procedure.

Her story isn't as unusual as it might sound. In fact, it's all too common -- and that's why surgery is a lousy choice, since studies show a significant number of people who get these surgeries relapse.

Besides, you've got other options here.

I know you do, because I've helped cure diabetic patients myself. I say "helped" because this is one case where a doctor can only do so much. The rest is up to you, and I won't lie: It takes hard work, dedication and discipline.

But once you've done it, there's simply no going back to "mindless eating" or any of your other old bad habits -- and certainly no going back to a life of diabetes.

Gentlemen, there's one more reason for you to lose weight whether you have diabetes or not. Keep reading for more.
