For the past six weeks I’ve been experimenting with a very high fat diet where I’m getting 65% of my calories from fat. No, that’s not a misprint. The vast majority of my calories are coming fat, and a good chunk of that has been saturated fat. The very same fat you’ve been told to avoid for decades because it would “damage your heart, build up in your arteries, increase your risk of cancer and even lead to obesity.” Curious about how this was affecting my body, I scheduled a full blood panel with our doctor. After seeing the results of that blood work, I shared with my doctor the details of my diet and how I teach people that fat is actually beneficial. She warned me that while this diet may be working for me, I may be the exception to the rule.
Gary Taubes, in his ground-breaking book “Good Calories, Bad Calories”, dug through TONS of research and found something surprising. Fat, touted as harmful for your diet, is a lie. And it’s a lie that has been covered up and repeated so many times, it’s been accepted as truth. We all know what that’s like – we all have that one friend whose stories are so far out of whack but so often heard, that we begin to believe them. I was guilty of thinking this way too; most of us at some point have been. However, not only did Taubes’ studies uncover the truth about saturated fat and cholesterol – both wrongly put on the “naughty list”, but new studies are now showing just how beneficial they really are[i].
One study centered on coconut oil, which is a fantastic oil to use for cooking and baking, in shakes, and when topically applied, is a detoxifying agent for skin. Coconut oil is very heavy in saturated fat. It has higher saturated fat content than red meat, which by the way, has more monounsaturated fat than it does saturated. Yet, thanks to the misguided war on red meat and saturated fat, we’ve come to believe that red meat is loaded in this stuff. But I digress. A Brazilian study showed that when middle-aged women replaced their intake of canola oil with the EXACT number of calories from coconut oil, an interesting thing happened. Their HDL (good cholesterol) increased, triglycerides lowered, and they lost abdominal fat. By including more saturated fat from coconut oil in the diet, regardless of the calorie content, several markers for heart health and diabetes risk drastically decreased. I’ll bet they looked younger and more vibrant as well.
It’s unfortunate. We’ve been told for decades to avoid these foods and build our diet around “good” carbohydrates. Yet, sadly, a high carbohydrate diet can promote weight gain for most people, decrease their HDL, and increase their triglycerides; this is in complete opposition to what conventional dietary wisdom says will happen. And yet we wonder why our children are obese at such young ages, and why our health across the nation is worse than ever. Even my doctor wonders why the vast majority of her male patients don’t have HDL numbers as good as mine.
Personally, I don’t believe it’s “simply” a matter of will-power, or one of individual responsibility. There are tens of thousands of people who spend hours at gyms and fitness clubs throughout the country, but who are frustrated that the pounds just won’t come off. I see it every single day. These folks tell me they’re eating healthy foods, have cut back on saturated fat and cholesterol, and are increasing their whole grain consumption. Are you seeing the pattern yet? This is NOT WORKING. Living a lifestyle with these parameters only causes us to avoid the foods – the REAL foods – that help to control our appetites, our weight, and lower our risk of disease.
So, how has a diet of high fat and high cholesterol worked out for me? Below is a picture of my results. Look specifically at the numbers circled in red.
These numbers squash claims that saturated fat and cholesterol are the “bad guys”. We’ve been told that red meat, eggs, and bacon increase our blood cholesterol. But I eat these foods everyday and it looks like I’m doing just fine. In fact, I’m doing better than a lot of people. The studies I’ve mentioned prove that though your total cholesterol may go up, it’s your HDL that’s holding the torch, and the LDL that’s struggling to catch up. When she saw my HDL of 71, my doctor’s eyes widened, “I almost never have guys with levels that high.”
If you’re not familiar with triglycerides, they are another piece of the puzzle that can clue us into our health status. When levels get above 150, doctors will get worried that you are at a higher risk of heart or diabetes issues. Mine clocked in at a low 45. My high fat, low-carbohydrate diet lowered my triglycerides. My daily shot of fish oil doesn’t hurt either.
How can you predict the future of your heart health? Take your triglycerides and divide them by your HDL. This is your triglyceride to HDL ratio (TG:HDL). As your ratio creeps above 3.0, the risk of heart problems is increased. Aim for 2.0 or lower, which is optimal. My TG:HDL ratio is a svelte .63.
At this point, I should note that genetics are not on my side. Heart disease runs rampant on both sides of my family, affecting both parents at an early age as well as my father’s parents. As the saying goes, “genetics load the gun, lifestyle pulls the trigger.” By steering clear of the lifestyle habits on which I was raised, I was able to avoid that smoking gun. High blood pressure also runs in my family and mine is usually “normal” at 120-125/80-85. While on this low-carb diet my blood pressure has only improved and is now usually at 110-115/65-75. No surprise here as a high carb diet will elevate insulin levels which in turn will raise blood pressure. Plus, you retain more water on a high carb diet which will also increase pressure. If anything, I’ve been adding more salt to my diet lately because I’m eating more vegetables. It’s no wonder so many people have high blood pressure these days. They’re just following conventional dietary wisdom.
The American Dietetics Association still supports the idea that saturated fat plays a role in increasing our odds of Type 2 diabetes. Yet, if we look at my A1C levels above, which is an average of blood sugar over the past three months, I’m well below the pre-diabetic category, let alone the diabetic one. Some health practitioners believe that 4% is ideal, so personally I’d like to see my number even lower. But after six weeks of this lifestyle, I’ve been able to bring down my fasting blood sugar by almost 10 points.
These recommendations of antiquity, in my opinion, immensely contributed to the obesity epidemic we see today. In fact, many of us don’t see it at all; we take it as the norm. But our “norm” shouldn’t be to expect heart disease, Type 2 diabetes, cancer, and Alzheimer’s as inevitable. Regular physical activity and REAL food will heal your body and your mind; which may give your doctor a stroke, metaphorically, of course.
So, eat up America! Red meat (from pasture/grass-fed cows), organic/local eggs (yes, yolk included), and organic bacon is back on the menu. Skip the stuff that comes in packages and anything that has a shiny and colorful “healthy” sticker on it. Remember this: health doesn’t come packaged like a toy in a cereal box, or down the chip isle at the organic store. All we have to do is eat REAL FOOD.
