Are you distracted by diet information on the internet? The internet can be confusing I work at Duke University. I’ve been there since 1990, studying low-carb keto diets since 1998. I find that a lot of people come to me with the darndest questions. Many of these questions come from

A recent study has come out saying dietary fat is bad. There will probably be more coming that say dietary fat is bad and there have been many before that say that dietary fat is bad. I don’t believe them. I’ll tell you why. Context: the Atkins diet Years ago,

How to lose weight I’ve heard people saying lately, “I’m not eating enough; that’s why I’m not losing weight.” Does that make sense to you? To eat more so that you can lose weight? The reason is that there’s an internet urban legend that the less you eat, you go

If you think that a keto diet has to be difficult and you have to calculate macros, use apps, write down everything you eat, and buy expensive, fancy foods, guess again. You don’t have to do all that. “Lazy, dirty keto” is the phrase for what I’ve been teaching and

Is there an association with the keto diet and muscle cramps? Any effective weight loss program will have some side effects. It’s not just the keto diet that can lead to muscle cramps. The main thing is that not everyone gets muscle cramps. People think of the cramps as part

What is “prescription strength keto”? Like any prescription strength thing, prescription strength keto is stronger than other versions of it – stronger than ‘over-the-counter’.
