May 30, 2020 — Like a dog with a bone, Nina Teicholz is not ready to let it go. She has a point to make and a book to sell. It’s all about pushing everyone to eat a low-carb diet. No matter what the problem, we find her telling us that low-carb diets, with plenty of saturated fats, are […]
May 8, 2020 — One of the very few blessings of the pandemic lockdown has been a respite from keto mania. Yes, we’ve had to blot out stupid talk about the Quarantine 15. Nonetheless, rants from true believers in ketogenic diets have been on the back burner. Interest in keto everything is down by more than half from where […]
January 25, 2020 — Some people call it the macronutrient wars. We call it a relentless pursuit of macronutrient magic. Consumers want to eat healthy, whatever that is. In the 1980s and 90s, it was low fat. In this millennium, that’s shifted to low-carb and keto approaches. But a new study in JAMA Internal Medicine offers a clue that […]
November 14, 2019 — Are we ready for another round on carbs, fat, and protein? It sure seems like it. Popular interest in low-carb diets keeps growing steadily. A more extreme version – keto – generates a lot of buzz right now. And yet, research keeps telling us that playing around with these macronutrients doesn’t make a huge difference. […]
May 19, 2019 — Low-fat diets are back in the news this week. An impressive and important randomized, controlled clinical trial started way back in 1993 to test the possibility that a low-fat diet might reduce the risk of breast cancer in women after menopause. Needless to say, a lot has changed in 26 years since then. Back then, […]
September 16, 2018 — Perhaps the backlash against decades of faulty low-fat dietary guidelines is peaking. It’s now popular to suggest that bad dietary advice in the 1980s sparked the epidemic of obesity that’s still booming today. But like so many other glib proclamations on the subject, this one is probably wrong. Or at the very least, it glosses […]
July 14, 2018 — Over the last 15 years or so, we’ve shaken off some bad dietary advice that swallowed us in the 1980s. Low fat everything was supposed to be the foundation for a healthy diet. Until it wasn’t. But one piece of that dogma has held its place in dietary guidelines. The 2015 guidelines for Americans still […]
February 21, 2018 — JAMA is out with a big, important study of low fat versus low carb dietary strategies. And the study has a null result on three hypotheses the researchers were testing. The results showed no differences in outcomes between the study groups. Low fat was no better than low carb. Also, neither genetic nor insulin secreting […]
August 18, 2015 — The intense popular fascination with low carb diets and speculation that they are metabolically superior to low fat diets has long been a little tired. Admittedly, low fat everything in the 1980s — with a little sugar thrown in to make up for lousy flavor — was probably not such a good idea. But a hamburger […]
