It doesn't take cutting-edge science to realize that a sugar-filled high-carb diet of slop has turned us into a nation of porkers.

Just take a look around you.

But the latest science shows that our growing guts may be getting some unwanted help… from stomach bacteria that flourish on junk.

Now, don't go blaming the bacteria for your bulging belly just yet. While this research is interesting, at the end of the day YOU still have complete control over your waistline.

In this latest study, researchers at the Center for Genome Sciences at Washington University School of Medicine in St. Louis genetically altered mice so they had no natural "gut flora" of their own.

Then, they inserted the human stomach bacteria into the rodents. The researchers found that the mice suddenly got fatter, whether they ate junk or health food - indicating that the bacteria was playing a role. In fact, they found that the bacteria caused big changes inside the stomachs of the mice within 24 hours.

I bet it's a matter of days before someone starts selling a probiotic drink aimed at these bacteria… and even the researchers say they think that someday food could be genetically modified to keep your stomach bacteria in balance.

But that's completely missing the point. There's a lot more to your waistline than the gut flora living beneath it, even if they do have a role in the process.

If you're fat, the real reason for your obesity is the junk you stuff down your own throat in the first place. Stop gorging yourself on high-carb garbage, and you'll stop getting fat - no matter what kind of bacteria are setting up shop in your gut.

And since these things are feeding off sugars and carbs, then the simple answer is to cut them off.

I challenge you to see if my diet fails. I know it won't.

Cut out all the sugar and bad carbs and load up on healthy animal fats and fresh vegetables. You don't need to life a single dumbbell. Just change your eating habits, and you'll be thinner and healthier than you've ever been.

And yes, that's all you need to get fit.
