Most of us have tried dieting at some time or another.
In fact, more than 70 million Americans are currently on a diet, but which one is right for you?
Doctor Stuart Trager says our weight loss approach needs an overhaul.
The DNA diet could be just what we need.
Here is how it works: a swab of DNA reveals a person's risk of heart disease, diabetes and other problems.
Diet suggestions are then made to lower those risks and weight, but some doctors say it is a sham. "If you can pick the small parts that have the greatest chance of impacting your overall health, that's a tremendous opportunity," says Dr. Trager of Pennsylvania Hospital.
Dr. Serge Jabour of Thomas Jefferson Hospital adds, "You may hear people saying that they're losing weight on it. Of course, when you give people some common sense advice, people lose weight."
You can get your DNA tested through high-end wellness centers, nutritionists and there's even an over the counter version.
Wellness centers could charge up to 2500 dollars. The over-the-counter version will set you back about $100.
