Ask Dr. Gourmet

Is the Atkins diet safe in general and if so, is it safe for Coumadin (warfarin) users?

Dr. Gourmet Says....

The research now shows that the Atkins diet is safe. Multiple research studies looking at a variety of low-carbohydrate diets show this. That said, the research also shows that it is not the best way to eat and the Mediterranean style diet is the winner when it comes to being a healthy choice that folks can follow and live with on a long-term basis.

For me the Atkins diet is just plain silly. I just can't imagine giving up pasta, potatoes, bread and rice. It simply makes no sense when we know that the key to weight loss is eating fewer calories. There's great research to show that it doesn't really matter how you get those calories (low fat, low protein, low carb, etc., etc.). Again, what matters most for weight loss is simply not eating as much. So don't give up a wide variety of great food, just eat less of it and eat foods that are high in fiber, lots of fruit and veggies, nuts, lean meats, fish and great quality fats.

The Atkins diet may or may not be safe for those on Coumadin® (warfarin). It's possible that the lower amount of carbohydrates could change the intestinal bacteria that do have an impact on Vitamin K levels. If you are planning on this type of diet, talk with your physician so that you can monitor your INR levels carefully.
