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. (You may have been led to believe that seed oils’ health effects have been thoroughly examined. They have not. And I’m writing another article that exposes why the nutritionists who claim to cite…

How Academics Use Inaccurate Data to Hide Correlations Between Seed Oils and Obesity

Most nutrition experts claim that the majority of evidence shows seed oils are healthy. But that evidence is not real. Most nutrition experts overlook, or make excuses for, the selective use of flawed, self-reported dietary data that makes seed oils appear beneficial.

Toxic Seed Oils Turn French Fries Toxic, Sadly

French fries are a beloved indulgence, but the toxic seed oils used to fry them can transform this treat into a health hazard. You may have seen this photo of cigarettes in a French fry cup before. It’s an AI-generated image. But it’s not just a made-up meme. It started circulating shortly after I was interviewed for this movie. During the interview, I made the rather shocking comparison between cigarettes and French fries. That comes from a study called: Toxic Lipid Oxidation Product (LOP) Generation in Culinary Frying Oils (CFOs) During High-Temperature Frying Practices: Passage into Fried Foods. In it,…

> Tears of joy

I'm crying tears of joy and appreciation for all you've done for me and my health! Without Deep Nutrition and Fatburn Fix, I would literally still be in the vicious cycle I'd been fighting all my life! In a nutshell - I am no longer a compulsive overeating addict suffering under the crushing 'thumb' of all food and alcohol.

Saved my life

I would like to thank you for literally saving my life. Back in February, I had to be hospitalized while on vacation in Phoenix with an A1C of 11% and had to start taking 2 types of insulin and 2 other meds. I read the Fatburn Fix in April, and followed the program to a tee, and I’m down by 15 pounds, 6.8 A1C, and only one once weekly diabetes medicine.

The key to unlocking my fatburn

I love your Fatburn Fix! Has helped me so so much! I have had the dreaded weight all my life - 20 or so pounds I could never shed. I have lost that now. I only eat 2 meals a day lunch and dinner with a glass of milk or cappuccino around 4 to hold me over. No snacking and not bad oils. It has been the key to unlocking my fatburn.

I feel great

My waist is four inches smaller. I feel great and many of the minor aches and pains that I had (knees and lower back) are gone. Also, my muscle tone is amazing, even though I have not increased my workout routine.

Lost a solid 20 lbs and my bloodwork is great

I have lost a solid 20 lbs and my bloodwork (after 3 months of eating your way) was even better! I was metabolically healthy (per your book) before I read your book, but barely. Lowering my weight, sealed the deal! I have been talking about you and your book to anyone who will listen...Thank you for all you’ve done and what you continue to do! You are changing lives for the better!

I’ve lost over 50 pounds

I’ve lost over 50 pounds. I’m 56 years old. Cutting processed food and unhealthy fats from my diet was one of the first things I did on my health recovery journey...I went cold turkey off the bad oils. Emptied my pantry into the trash and just started eating real food

Heart Palpitations have Stopped

I’ve lost 20+ pounds (also fasting 16-24 hours daily) and haven’t had palpitations except for one occasion — I had a mini bag of Fritos for the first time in July. And, I feel better now on a daily basis than I ever did all through college.

My allergies disappeared

The biggest difference for me (and a surprising one) is that my allergies have almost completely disappeared! This is a big deal for me, because I’ve had allergies most of my life and they have often affected what I do which is a teaching music in [a public school district]. In general, I feel much better and have more consistent energy throughout the day.

Better than ever

I am an anesthesiologist in Orlando and a huge fan of both of your books! I have been incorporating your principles for the last 10 months and feel that my health is better than ever.

I feel so much better

I had terrible aches and pains everywhere in my body, my hands, shoulders and knees. I feel so much better and the way I feel is motivating me every day! Thank you

I feel free

For the last month, I have really been reading all labels on everything. I have completely remove those 8 oils you talk about. I must tell you, I feel great! I have more energy and I am now 197 lbs (have always been around 205 to 210lbs). I eat potatoes with real butter, grass fed steak, pasta with the right toppings. I eat everything! I seem to crave less sugar. I love it!
