Millions of Americans suffer from low energy, digestive discomfort, and trouble losing weight. Many also are on the road to serious heart problems.

According to Dr. Steven Gundry, one of the top cardiothoracic surgeons in the world, all these issues can be addressed by doing one simple thing.

"The key to weight loss is the same as the key to great heart health," says Dr. Steven Gundry. "It's not adding anything to your diet. It's taking away one thing."

According to Dr. Gundry — who has studied weight loss and heart health for over 30 years — certain foods contain a dangerous chemical that wreaks havoc on our bodies. This, in turn, leads to digestive discomfort, food cravings, fatigue, weight gain, and even worse health issues.

Fortunately, by simply cutting out the dangerous foods, Gundry has seen thousands of people reverse these troubling conditions. Dr. Gundry himself lost 70 pounds after making this one dietary change... and has kept the weight off for over 20 years.

"It's easy. You just need to know what foods to avoid," he recently told a crowd of over 1,000 people while speaking with world-famous self-help guru Tony Robbins, who is also his most well-known patient.

Now, for the first time ever, Dr. Gundry has created a short video where he explains everything about the true cause of weight issues, including how people can naturally fix it, on their own, right from home.

The video is presented below by Dr. Gundry, free and uninterrupted.

So far, the reviews have been stunning, with viewers saying their issues improved in a matter of weeks or even days.
