The Best Cure for Post Holiday Sugar Cravings

How to Stop Sugar Cravings After the Holidays If you struggle with sugar cravings, the holidays can feel like a complete derailment of your progress. But it’s not as bad as it feels. These cravings are not a personal failure—they reflect an underlying metabolic issue that was never fully resolved. Until that issue is addressed, post-holiday setbacks are not only common, they’re predictable. That underlying issue is insulin resistance. Sugar and carbohydrate cravings are best understood through the lens of metabolic health. When insulin signaling is impaired, the body has difficulty regulating energy availability, which intensifies cravings and makes willpower…

The 2025 Dietary Guidelines Are Beginning to Acknowledge the Problems with Seed Oils

Why It Matters That Seed Oils Are Being Recognized as Ultra-Processed The US Dietary Guidelines will be released in just a few days. They are expected to make a historic change regarding refined seed oils. Departing from decades of guidance that treats these oils as an unqualified nutritional upgrade, they’re calling out the fact that most seed oils are ultraprocessed, and their health effects merit closer examination.

Is Cold-Pressed Sunflower Oil Actually Heathy?

“Cold-Pressed” Doesn’t Mean Healthy—When We’re Talking About Seed Oils Most people assume that “cold-pressed” means the same thing as “virgin” or “extra-virgin”—and therefore assume the oil must be healthy. That assumption feels reasonable, because with oils like olive oil, cold-pressing does usually mean the oil was not industrially processed. Sunflower oil, like all seed oils, is different from olive oil. In this article, I’ll explain why cold pressing sunflower oil (or any seed oil) oils does not make the seed oil healthy, what you want to look for instead, and why you’ll never find the healthy version of sunflower in…

Why My Magnesium Supplement of Choice is Magnesium Oxide

TLDR: I use and recommend Magnesium Oxide because it is more compact and easier to swallow. Also, being physically smaller, we only need to swallow a single pill. Studies claiming it doesn’t get absorbed are suspect. My approach to supplementation is minimal. I do recommend magnesium as well as a few other minerals and vitamins.

Low Smoke Point Olive Oil on High Heat–Is It Safe?

This is a particular concern for professional chefs who typically cook with temperatures far higher than those used by a home cook. If the oils aren’t smoking that must mean, the thinking goes, that they are chemically stable. No smoke, no free radicals, no toxins. No problems. But I want you to set aside, for a moment, everything you’ve been told about smoke point…

New Deep Nutrition – Available NOW!

If you’ve followed this website for any length of time, you probably noticed I don’t do a lot of posting. It’s not that I don’t like to help you stay up to date on the latest nutrition news.
