When it comes to the topic of dietary fat, we’ve been sold a mountain of falsehoods over the past decades. The fats we were told were good, like industrial seed vegetable oils1, are actually largely toxic and can cause disease, while healthy fats can help protect against it. The good whole-food based fats, even quality saturated fats2, are an important part of a healthy diet.
We were told that eating fat made you fat and we heard little about sugar and refined carbs’ role in weight gain (or disease). The evidence is now clear though: Good fat is crucial to thriving health and the real triggers for weight gain are often sugar, refined carbs and bad fats.3 4 The healthy fats you eat in your diet, are not the same thing as stored fat in your body. There is a whole other set of mechanisms at play to trigger fat storage, and that fat storage is often born of glucose (sugar).
Having enough quality fats in your daily diet actually tends to increase metabolism and leads to sustained weight management. It’s important for most people to get enough quality fat when trying to manage weight. Our body needs nutritional caloric satiation to function properly. When you try to lose weight simply by calorie restriction, it actually reduces metabolism. It’s important to eat enough good fats so that your body isn’t overly stressed and can perform its key functions well.
Fat was also supposed to be the big cause of heart disease and a number of other health conditions. When it comes to healthy fats, the exact opposite is true. By depriving ourselves of the good fats we need, we’ve shifted towards needing to eat and burn sugar and carbs for energy, which are literally killing us!
Healthy fats are calorically very nutrient dense. They feed the body far more per calorie than carbs/sugar. Therefore, you get a much better bang for the buck and are able to satiate yourself more than you can with carbs/sugar. You have to eat a lot more carbs/sugar for your body to get the energy it needs to run than you do with fat. This is a particularly important point for those who are trying to manage their weight.
Now as I said earlier, there’s a big caveat. Highly processed and easily oxidizable and inflammatory industrial seed vegetable oils, which we’ve been told for decades are so much better for us, are actually a big villain. We’re talking canola, soy, corn, safflower, sunflower, the so-called “safe fats.” These oils are extracted through chemical processes, often using toxic substances.
Alternatively, good quality fats are essential to our existence. Here we are talking about:
- sustainably sourced palm oil,
- nuts and seeds,
- quality animal fats (grass-fed in particular),
- egg yolks,
- butter and ghee (yup, I said butter).
These are whole-food based fats. When not eating a whole food source, independent oils attained should be through expeller pressed methods, which, unlike toxic chemical processing, are safe and provide a nourishing food.
The good news is, by bringing in more healthy fats and replacing the bad, you don’t have to stop eating or cut something out of your diet, you’re simply swapping it with a form of fat that is much healthier and actually tastes even better. So it’s a win, win!
You want your fat stores to be of the utmost quality. The industrial seed oils that are often oxidized before you even use them, work against your body in a myriad of ways. Source quality is always critical! You are what you eat.
Most people find that when they shift to a diet that burns more fat for energy instead of glucose, body weight quickly stabilizes and energy is gained. Fat and glucose burn differently in the body. In most cases, good fat actually speeds up our metabolism. And it’s a more sustainable source of fuel for prolonged energy.
Oxidization is not our friend:
A key risk of consuming bad fats occurs because of a process called oxidation.5 Oxidation is a disaster for the body, and another main driver of disease, including: heart disorders, cancer and strokes. This is one reason that most vegetable oils are a problem. The bad ones oxidize easily.
Oxidation is damage caused by oxygen. It’s like when apples or bananas turn brown from air exposure. This happens with fats too, and it’s essentially what happens inside your body when you eat oxidized oils. It’s kind of like rusting on the inside. The ensuing “oxidative stress” creates “free radicals” that are inflammatory and can damage your body. Most of the bad and highly refined vegetable oils listed above cause great risk of this happening inside you.
Fried foods from industrial seed vegetable oils, leave your cells and arteries looking just like the fried foods — rugged, crusty, torn. They disable cells functioning in the short term, and ultimately destroy healthy cells, causing heart attacks and strokes. This process is also how oxidation fries arteries! While eating food fried in these bad oils is the worst of the worst, eating the oils themselves generally does the same thing over time. Eating fried foods from these oils is one of the very worst things you can do to yourself. It creates both short term damage and suffering as well as dire consequences in the long term. (You can fry your own foods in certain oils; see below for more details).
Trans & Hydrogenated Fat:
This type of fat that is now universally understood to be toxic and linked directly to coronary artery disease is called trans fat, or hydrogenated fat. Transfats and hydrogenated or even partially-hydrogenated oils are highly processed foods, typically made from industrial seed vegetable oils. They are created this way through processing, so that they can be more “shelf stable” and thus cheaper and easier to produce and store. These fats should be avoided at all times. Be mindful, even when your label says “0” trans fats, it can still include some as it allows for .5 grams or under to be listed as “0”. The more processed foods you eat with these bad oils, the more the grams will add up. ANY amount will do damage.
The lesson here: ditch the margarine and bring back the butter!

Learn more about fat from the experts: For those interested (or who need more convincing), you can really geek out on the various types of fat our body needs, and those it doesn’t. There are so many roles fat plays in thriving health. If you are interested in learning more, I’d highly suggest reading the work of Dr. Mark Hyman and/or Dr. Catherine Shanahan. Google their names along with the word “fat” for a myriad of informative articles and videos. Here are a couple of good ones:
