Diets don’t work? Or does bad science generate bad data?

One of the problems with diets is their focus on weight loss, not improved health.  A recent study in Circulation states that it doesn’t matter what diet you follow for weight loss (1).  On the other hand, we have the American Heart Association diet, the American Cancer Association diet, and the American Diabetes Association diet. … Read more »

What if gluten sensitivity doesn’t exist?

How can I possibility make that statement?  Two recent best-selling diet books have maintained that gluten makes us fat and dumb (1,2). Billions of dollars are spent on gluten-free (but carbohydrate-rich) food products.  And people feel better when they don’t eat bread. Before explaining my statement, let me make two things very clear.  First, I… Read more »

Trying to Make Science Out of Sausage

Epidemiology is the study of associations and not causality. It essentially began in 1854 when John Snow noticed that there seemed to be a higher concentration of cholera patients in a certain area in London during one of its many cholera epidemics in the 19th century. That’s an association. The real breakthrough for John Snow… Read more »

Practical hints for helping to manage brain trauma

More Cholesterol Madness

This week the American Heart Association announced a doubling down on its bet on cholesterol and heart disease.  It certainly wasn’t because there was a sudden epidemic of heart disease, because death rates have been falling since 1970 (20 years before statins were introduced).  Nor has there been any new clinical data showing the benefits… Read more »

Anti-aging made easy

Anti-aging diets have been around since the 15th century, starting with the books written by Luigi Cornaro. Although I addressed the history of Luigi in my book The Anti-Aging Zone written more than a decade ago, it bears repeating. Finding himself near death at age 35, Luigi Cornaro went on a strict calorie-restricted diet consisting… Read more »

Omega-3 fatty acids and prostate cancer? Oh, really?

There was a recent publication suggesting that higher levels of omega-3 fatty acids are associated with a greater risk of prostate cancer 1. Of course, the immediate media response was to indicate that taking fish oil supplements is dangerous. Of course, let’s not forget, then, that eating fish must also be dangerous. Before letting the… Read more »

Why doesn’t exercise and diet reduce heart disease for diabetics?

That’s a good question after the June 24 issue of the New England Journal of Medicine reported on the failure of long-term diet and exercise to reduce heart disease in diabetics1. It had been known from earlier and shorter studies that diet and exercise in diabetics appeared to generate a decreased risk of cardiovascular disease…. Read more »

Good Diet, Bad Study

As the creator of the Zone Diet, I am a strong believer in the Mediterranean diet as a lifetime dietary program for good health. In fact, the Zone Diet can be considered to be the evolution of the Mediterranean diet as it provides even greater anti-inflammatory benefits. That being said, this week’s New England Journal… Read more »

A study from Harvard Medical School explains that even though people can lose weight on a ketogenic diet, all lost weight usually rapidly returns. Ketogenic diets have been recommended for decades for rapid weight loss. The most famous is the Atkins diet. Ketogenic diets are based on high-protein and very low-carbohydrate intake. For the past… Read more »
