U.S. News Study Is Flawed

Sometimes I just have to roll my eyes when I hear about nutritional experts rating diets. The reason is that apparently none of the “experts” actually reads the published data critically. Undoubtedly, one of the worst offenders is the annual U.S. News and World Report study on diets. After watching them year after year making… Read more »

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 »

That being said, this week’s New England Journal… Read more »

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.

“Biggest Loser” or Best Zoner?

A few weeks ago I spoke at the American Society of Bariatric Physicians. Later in the day I heard an interesting lecture from the lead dietician for the TV series “The Biggest Loser”. In this lecture, she disclosed all the keys for successful weight loss in the individuals on the show. The first was incredibly… Read more »

Changing Gene Expression

I have often stated that the real power of the Zone Diet is to change gene expression, especially the expression of anti-inflammatory genes. What I never realized is how rapid gene expression could occur.

Eat Less, Get Hungry

Telling an obese person simply to eat less rarely succeeds. Is it because they are weak-willed individuals or is there something more complex going on?
