The End of Dieting
The multi-billion weight loss industry has a dirty little secret: Dieting doesn’t work. To be sure, almost any diet out there will produce weight loss if you follow the rules. However, the majority of people who lose weight on diets will eventually gain it all back. Often, with interest. Don’t despair: I do have a solution! Find out more in this week’s show.
Do Grains Decrease Colon Cancer Risk?
Q. After doing some research, I have been trying to reduce my intake of grains. But the big thing in the news this week is a new study finding that fiber from grains reduces the risk of colon cancer and that fiber from fruits and veggies doesn’t have the same effect. Have you looked at this new research? Do you still recommend reducing grains?
A. Just to be clear, I’m not anti-grain. Although I suspect that most Americans consume an excessive amount of grain products (especially refined grains), and I believe that grains are not essential to a healthy diet, I still think that a healthy diet can include grains (especially whole grains).
I have, however, questioned the dogma on the “benefits of whole grains” on the basis that the research doesn’t really distinguish between the benefits of adding whole grains and the benefits of reducing refined grains. (The two virtually always go hand in hand.)

But that doesn’t mean that you have to count calories in order to lose weight. Read or listen to this week’s show.

Is Eating More Often Really the Key to Staying Thin?
A study in this month’s Journal of the American Dietetic Association reports that people of normal weight eat more frequently (5 times per day on average) than overweight people (who average 4.2 times per day), suggesting that eating more frequently may be a key to maintaining a healthy weight. At least, that’s what all the headlines will say–and this will fuel the popular myth that eating more frequently “revs up your metabolism.”

Is MSG Bad for You? Part 2 of 2.
The FDA and EU consider MSG to be a harmless flavor enhancer; critics claim it’s a dangerous toxin. Who’s right? Last week, I explained what MSG is, how it acts in the body, how it’s used in the food supply. This week, I take a closer look at charges that MSG causes headaches (“Chinese Restaurant Syndrome”), neurological damage, or has harmful effects on insulin, diabetes risk, or even obesity.
