New study in The New England Journal of Medicine finds impressive evidence that weekly semaglutide injections produce clinically significant weight loss as well as many other benefits, approaching the improvements seen with weight loss surgery. Not a definitive answer to obesity, but a very encouraging step in the right direction. Science works.… read more "A New Medication to Combat Obesity"
The human body is clearly not the product of an intelligent designer. Its many flaws tell the fascinating story of evolution’s accidents and constraints. In his new book Human Errors: A Panorama of Our Glitches, from Pointless Bones to Broken Genes, Nathan Lents, a professor of biology at John Jay… read more "Human Flaws Demonstrate Evolution, Not Intelligent Design"
Gary Taubes writes that sugar is the cause of obesity and most chronic diseases. He makes a good case for the prosecution, but he doesn’t convict. Gary Taubes is a journalist on a crusade. In two earlier books, Good Calories, Bad Calories and Why We Get Fat: And What to Do About It,… read more "Gary Taubes and the Case Against Sugar"
The 2014 film Fed Up is an advocacy documentary. Its message: There is a worldwide epidemic of obesity. It is endangering our children. Increased sugar consumption is responsible. The food industry is responsible for our increased sugar consumption because it puts hidden sugar in processed foods, bombards us with advertising, favors profits… read more "Does the Movie Fed Up Make Sense?"
Gary Taubes has written two books explaining why people get fat and why a low-carb diet is the solution to preventing and treating obesity. He didn’t like what I had to say about his books on this blog back in 2011. I was not the only one to criticize. Another reviewer accused him of “abandon[ing] journalistic… read more "Gary Taubes and the Cause of Obesity"
In the past I have criticized evolutionary medicine for its tendency to rely on unverifiable “Just-So Stories,” but a new book has helped me appreciate what the best kind of evolutionary thinking can contribute to our understanding of medicine. Doves, Diplomats, and Diabetes: A Darwinian Interpretation of Type 2 Diabetes and Related… read more "Doves, Diplomats, and Diabetes"
Being fat is bad except when it’s good. It’s called “the obesity paradox.” (No, that isn’t a mis-spelling for “two physicians who treat fat people.”) The adverse health effects of obesity are well established, but there are exceptions. Obesity appears to confer an advantage in certain subgroups with conditions… read more "The Obesity Paradox"
A number of buzz-words appear repeatedly in health claims, such as natural, antioxidants, organic, and inflammation. Inflammation has been implicated in a number of chronic diseases, including diabetes, Parkinson’s, rheumatoid arthritis, allergies, atherosclerosis, and even cancer. Inflammation has been demonized, and is usually thought of as a bad thing. But… read more "Inflammation: Both Friend and Foe"
I recently received an e-mail from a high school science department head who is teaching a unit on nutritional science. He asked for my opinion of a YouTube video of a lecture advocating a high saturated fat diet. The speaker is Donald W. Miller, Jr., M.D., a cardiothoracic surgeon at… read more "Eat Fat, Get Thin?"
Journalist Gary Taubes created a stir in 2007 with his impressive but daunting 640-page tome Good Calories, Bad Calories. Now he has written a shorter, more accessible book Why We Get Fat: And What to Do About It to take his message to a wider audience. His basic thesis is… read more "Why We Get Fat"
