Liz Mckinney, CNS, LDN continues to examine the big fat myth and share some more information and sample mean plan to incorporate the dietary changes of a high fat diet into your busy lifestyle. Our last blog post caused quite a stir and we want to be sure that our readers understand the differences between ‘good fats’ and ‘bad fats.’ One big take home point is that not all dietary fats are created equally. So, what does the science tell us about a high fat diet? To recap our last blog article, research is showing that a high fat made up of healthy fats coupled with a low carbohydrate diet can be beneficial for:
High fat diets, and even ketogenic diets are being studied for their efficacy in treating Parkinson’s, Alzheimer’s, ALS, Epilepsy and even ADHD. More and more, we understand there is a significant effect on our physical and emotional health exerted by our food consumption, even anxiety and depression can be effected by our diet. In particular, of the vital and nourishing micro nutrients, cholesterol is especially protective of brain function. One famous study called the Framingham Heart Study found that those with low serum cholesterol performed less well on cognitive function tests than their counterparts with borderline or high cholesterol levels. We can infer from this correlation that cholesterol does seem to have a protective effect on the brain. Additionally, when we note that their are ramifications for those who take statin drugs to lower their cholesterol. One known side effect of statin drugs are problems with memory and cognition.
Adding more fat to your diet the healthy way.
The good news is that it’s easy to start enjoying the benefits of a high fat, low carbohydrate diet. It’s important to limit grains and legumes to maintain the benefits. It is best to try to aim for only about 60 grams of carbohydrates a day. Along with unlimited non-starchy vegetables (think asparagus, cauliflower, broccoli, kale, swiss chard and spinach) and low sugar fruits (grapefruits, oranges, apples, berries, melon, pears, cherries, grapes, kiwis, plums, peaches and nectarines), enjoy ample amounts of these ‘good or healthy fats’ which are foods which will accelerate health and allow you to experience the benefits of a high fat diet:
Breakfast:
2 scrambled eggs with 1 oz. goat cheese cheese and stir fried veggies (onions, mushrooms, spinach and red bell pepper)
Lunch:
4 oz. baked chicken or canned tuna with a side of leafy greens dressed in balsamic and olive oil
Dinner:
3 oz. grass fed steak with a side of roasted broccoli and mashed cauliflower
Dessert:
3 squares of 70% dark chocolate

So go ahead and give it a try, of course one should always consult either your PCP or a dietitian or nutritionist before making any changes to your diet, this is especially true if you have preexisting health conditions.

Big Fat Myth, High Fat Diet and how it affects health.
Open a women’s magazine or examine the back of a food label, you will find the ‘evidence’ there. It’s easy to find ready sources that say dietary fat is bad news for your waist line, cholesterol, skin, mood, you name it. Many clinicians still hold that saturated fats like coconut oil, butter and beef cause weight gain, clogged arteries, high cholesterol and heart disease. But, according to Certified Nutritionist Liz Mckinney, there is much to learn when it comes to the Big Fat Myth, read on to re-evaluate fat’s bad reputation. This blog will fill you in on the facts and research in order to assist your physical health, emotional health, and wellness goals by consuming fat and nourishing yourself with this well known macro-nutrient.
Today, a common scenario occurs when a patient walks in for a checkup or health screening and they learn that their cholesterol is high. The patient is then told to limit saturated fat and cholesterol intake. Cut down on foods such as red meats, butter, eggs, and oils like palm and coconut) and often a prescription for a statin drug follows when their cholesterol is over 200 mg/dL. This is probably due in part to misleading evidence that suggested that cholesterol levels are directly correlated to risk of heart disease. One such study was performed by a researcher by the name of Ancel Keys in the 1980’s that looked at 22 countries and found that dietary fat intake was related to increased risk of heart disease. However, data on only 7 of those 22 countries was published – those that fit his hypothesis. Since then, many researchers and physicians have refuted this study, and yet, the recommendations that come down the pipe from the American Heart Association and the USDA continue to perpetuate that dietary fat and cholesterol are bad for us.
Research continues to show that high quality animal fats and eggs aren’t the real culprit in heart disease. One of the most notable studies that shows this was called the Women’s Health Initiative, which studied over 48,000 postmenopausal women and the connection between a low fat diet and the risk of heart disease. Participants were followed for an average of 8 years and then assessed for heart disease. The group that reduced overall fat intake and increased intake of whole grains, fruits, and vegetables did not experience reduced risk of Coronary Heart Disease (CDC), stroke or CVD, over the control group. There are other studies that have found similar results, indicating that low fat diets don’t really have much impact on heart disease risk. A report published in 2010 by the American Journal of Clinical Nutrition stated that there was no substantiated link between saturated fat intake and outcomes of obesity, CVD, cancer or osteoporosis. And, if you need even more proof, a meta-analysis of 21 medical reports and studies also published in 2010 in the American Journal of Clinical Nutrition concluded that, “the intake of saturated fat was not associated with an increased risk of coronary heart disease, stroke, or CVD.”
So, if saturated fats aren’t the culprit in CVD and atherosclerosis, then what is? Enter carbohydrates. Most grains and sugars are highly inflammatory. As a society, our diets are high in processed and packaged foods like pastries, fast food, crackers, cookies and cakes. Eating these foods causes surges in blood sugar and taxes the pancreas, whose job it is to produce insulin to shuttle the sugar into our cells to be used for energy or stored for later. Over time, the cells become resistant to insulin and sugar remains in the bloodstream instead of being transported into the cells. Sugar in the blood stream sticks to protein molecules like LDL cholesterol (called “bad cholesterol”). This changes the structure of the LDL and causes an inflammatory cascade which leads to plaques in the arteries and the inability of LDL to carry cholesterol where it’s needed,especially to the brain. So, now we have a simple equation. Too many carbohydrates cause inflammation, which leads to oxidized or damaged LDL and atherosclerosis. This is what leads to heart disease, not eating too much dietary saturated fat and cholesterol.
Read on and look for next weeks post, Liz will share more details about how your health and wellness can be bolstered with fat as she shares all of the well researched benefits to Fat. She will also share a sample meal plan to help you take advantage of the most nourishing food options available.
