your best diet

People get excited about their favorite diets. Maybe you do, too. Are you a low-carb champion or a low-fat fan? Which one really is your best diet?

The DIETFITS Study:

A big study from the Stanford Prevention Research Center assigned 600 people to either a healthy low-fat diet or a healthy low-carb diet. (No junk food allowed in either one.) People followed their assigned diets for a year and then the scientists compared the amount of weight lost by each group. Average weight loss was astonishingly close. Altogether, people in the study lost a total of 6500 pounds.

That might have been expected, since previous studies have shown a wide range of weight loss results within each type of diet plan and not much difference between them. The DIETFITS study (standing for Diet Intervention Examining The Factors Interacting with Treatment Success) planned to see if they could figure out which is the best diet for specific individuals. They looked at a metabolic marker, insulin secretion, and at a set of three genes that have previously been linked to weight. However, neither of these markers predicted who would do better on a low-fat regime and who would thrive on a low-carb approach.

More Work to Do:

Consequently, scientists have a lot more work to do before they can identify your best diet. But they did discover that emotional and psychological factors are important. People who were very successful at losing weight told the researchers that the study helped them change their relationship to food. Many found that becoming more mindful about their meals made a big difference.

    I believe ketogenic is the way to go for the most part. A very small amount of carbs is okay but lots of good fats and healthy vegetables and fiber is ideal.

    Dr Gardner mentioned name of book called The Gut Brain? By some of his colleagues. Can you pass along name and authors?

    Thank you! Great broadcast.

      Nancy, there has been a good bit of research recently on the connection between the intestinal bacteria and the brain. I’m not sure which book, specifically, he may have been referring to. We’ll check.

    Thank you! This was the best episode I’ve ever heard. It was also one of the best, most informative shows I’ve ever heard on any media. The bottom line is so simple, and yet it is very difficult to get the message out. So many people believe there’s just one more pill they need to take.

    Very enlightening carb verses fat relation. How would it be possible to get the code for the Vegathon app.

    Thank you
