Disturbing Data Demonstrating That Low-Fat Made Us Fat
“Saying we become fat by eating fat is like saying we become green by eating green vegetables.” — Paraphrase of Uffe Ravnskov, MD, Ph.D.
We are told that sugar-laden muffins, nutritionally neutered toast, and insulin-exploding juice are part of a balanced, nutritious breakfast because they are low in fat. After decades of this many of us now look at food and ask ourselves, “Is this low in fat?” If the answer is yes, we think it is healthy. Yet foods that contain fat are not necessarily unhealthy. Researcher M. Leosdottir from Lund University stated:
“Most researchers today agree on total fat intake not being a risk factor for cardiovascular disease or cancer.”
In addition to not killing us, foods containing fat do not make us fat. We’ve been told they do because a gram of fat contains more calories than a gram of carbohydrate or protein. Fat has nine calories per gram while protein and carbohydrate only have four. The problem is that fat’s higher quantity of calories does not mean eating it causes us to store body fat. That thinking is rooted in the Calories In – Calories Out theory of fat loss, which we now know is wrong.
According tothe National Academy of Sciences:
“Obesity itself has not been found to be associated with dietary fat in either inter- or intra- population studies.”
Harvard researcher W.C. Willett adds
“There is no good evidence linking dietary fat with excess weight. In fact, there is plenty of evidence showing that the percentage of calories from fat is not the culprit leading to excess weight…In country-to-country surveys across Europe, women with the lowest fat intake are the most likely to be obese, while those with the highest fat intake are the least likely.”
A fellow researcher at Harvard, F.B. Hu, makes a similar point:
“Although reduction in percentage of calories from dietary fat intake is commonly recommended for weight loss, long-term clinical trials have provided no good evidence that reducing dietary fat per se can lead to weight loss.”
This data seems counterintuitive because we’ve been led to believe that eating fat encourages overeating. We’ve been misinformed.
Think back to Satiety. Water, fiber, and protein play the biggest role in the Satiety of food, and Satiety determines how many calories we eat. Notice how there is no mention of fat there. Many water-, fiber-, and protein-packed foods contain fat. For example, seafood, meat, nuts, and flax seeds all contain fat. But when we focus on eating less fat, we replace these high-Satiety foods with low-Satiety starches and sweets. Since low-Satiety foods require more calories to fill us up, this swap causes us to eat more—not less—calories. So, far from discouraging overeating, avoiding SANE foods that contain fat encourages overeating.
The last four decades of data tell the same story. We were told to avoid eating fat, so we reduced our relative intake of fat, increased our intake of starches and sweets, increased our total caloric intake, and ended up heavier and diabetic as a result.
Less Natural Foods Containing Fat, More Overeating
Less Natural Foods Containing Fat, More Body Fat
How We Eat vs. Our Incidence of Weight Gain
How We Eat vs. Our Incidence of Diabetes
The government knows this too. The Centers for Disease Control and Prevention (CDC) reported:
“During 1971-2000, a statistically significant increase in average energy intake occurred…The increase in energy intake is attributable primarily to an increase in carbohydrate intake.”
Even the authors of the government’s guidelines—the U.S. Department of Agriculture—have gone on record stating that since the 1970s the major dietary trend has been a:
“greatly increased consumption of carbohydrates.”
They found that starch consumption had increased by nearly sixty pounds per person per year, and sweetener consumption had increased by nearly thirty pounds. That is ninety additional pounds of low-quality low-Satiety food—every year.
The emphasis on low fat leads to inSANEity and misses an important point. Long-term health and fat loss does not result from diets low in fat, carbohydrate, or protein. Fat is not evil. Carbohydrates are not bad. And protein is not dangerous. The best way to burn body fat is to be balanced andSANE.
However, when you look at the government’s pyramid and plate, balance is nowhere to be found:
The Food Guide Pyramid/MyPyramid
MyPlate
How are these balanced diets? They are high in carbohydrates and low in everything else. Consider the high-fat Atkins diet. It is called “high-fat” because it advises individuals to get 65% of their calories from fat. Look at the USDA’s pyramid and plate diets that advise us to get 65% of our calories from carbohydrate. Doesn’t that make them high-carbohydrate diets? This could be why the January 13, 2011, edition of USA Today poked fun at the 72% of Americans who claimed to eat a balanced diet. The implication: “How could 70% of you be overweight if you ate a balanced diet?” We could easily be overweight if the “balanced” diet we are told to eat by the government is actually out of balance.
This imbalance exists in other guidelines as well. The American Heart Association Nutrition Committee calls a 40% carbohydrate, 30% fat, and 30% protein diet a “low-carbohydrate/very-high-protein diet.” Since when does 40:30:30 indicate that anything is very high?
Balanced
Typical
Government Recommended
What could be the reason for this confusion? The answer lies in another myth that has been proven false: eating foods that contain fat leads to unhealthy cholesterol levels. We’ll dig into this cholesterol confusion in the next post.

$1,000,000,000 Worth of Research Later: Eating Fat Does *Not* Harm Health
The last post concluded with Harvard University researcher F.B. Hu informing us that “It is now increasingly recognized that the low-fat campaign has been based on little scientific evidence and may have caused unintended health consequences.” Here’s the supporting data I promised.
- When P.W. Siri-Tarino of the Children’s Hospital & Research Center in Oakland examined 21 studies which included a total of 347,747 people, he found: “There is nosignificant evidence for concluding that dietary saturated fat is associated with an increased risk of heart disease or cardiovascular disease.”
- The National Heart, Lung, and Blood Institute funded an enormous trial designed to link the consumption of foods containing fat to heart disease. The $115 million Multiple Risk Factor Intervention Trial took 12,866 men with high cholesterol, split them into two groups, and fed one group the government guidelines’ diet for seven years with the hopes of lowering the incidence of heart disease. The government’s diet resulted in a 7.1% increase in heart disease deaths.
- The Women’s Health Initiative of the National Institutes of Health completed a $700 million study to test the fat hypothesis. A whopping 48,835 women ate their normal diet or the government dietfor about eight years. At the end of the study, the regular- and government-dietwomen weighed the same and no differences were found in their health. The researchers concluded: “Dietary intervention that reduced total fat intake did not significantly reduce the risk of coronary heart disease, stroke, or cardiovascular disease.” As reported in the study: “[This] trial is the largest long-term randomized trial of a dietary intervention ever conducted to our knowledge, and it achieved an 8.2% reduction…in total fat intake…No significant effects on incidence of coronary heart disease or stroke were observed.” The New York Times ran the headline: Low-Fat Diet Does Not Cut Health Risks, Study Finds.
- A massive study named MONICA involved 113 groups of scientists and doctors in twenty-seven countries studying everything they thought could contribute to heart disease. They found little if any association between the average cholesterol level and heart-related mortality.
- In The Western Electric Study—known in academic circles as one of “the most informative prospective studies to date”—researchers concluded: “Although the focus of dietary recommendations is usually a reduction of saturated fat intake, no relation between saturated fat intake and risk of coronary heart disease was observed [in their study].”
There’s no shortage of data. In the Malmö Diet and Cancer Study, 28,098 men and women were split into four groups according to their intake of foods containing fat. After six years of observation, researchers found: “Individuals receiving more than 30% of their total daily energy from fat and more than 10% from saturated fat, did not have increased mortality. Current dietary guidelines concerning fat intake are thus generally not supported by our observational results [data].” Additionally: “With our results added to the pool of evidence from large-scale prospective cohort studies on dietary fat, disease and mortality, traditional dietary guidelines concerning fat intake are thus generally not strongly supported.” And the icing on the cake: “No deteriorating effects of high saturated fat intake were observed for either sex for any cause of death.”
I’ll briefly point out three more studies: the Nurses’ Health Study, the Health Professionals Follow-Up Study, and the Nurses’ Health Study 2. Together these studies tracked 300,000 people. None of these studies showed total fat intake increasing the risk of heart disease. The only conclusive finding was that eating more plant fats—such as the fats in flax seeds and nuts—lowers the risk of heart disease. The researchers involved reported:
“Intake of linolenic acid [unsaturated fat] was inversely associated with risk of myocardial infarction [heart attacks]…These data do not support the strong association between intake of saturated fat and risk of coronary heart disease suggested by international comparisons.”
The government was trying to help with the guidelines, but sadly, it failed. Even worse, it keeps on failing. Scientists know it, and the data show it. In the next few posts we’ll expose why we haven’t been told about it.
