Eating fats to a greater extent, as in ketogenic diets, and contradicting everything we knew about proper nutrition is now fashionable. According to the new food philosophy of low carb, paleo and ketogenic diets, meat can be eaten every day, pasta is the devil, gluten as well, sugars must be eliminated and often also dairy products and cheeses, legumes are off, fruit hurts. Instead, fats and proteins are the key to weight loss.
This position, although supported by a lot of scientific research, is a bit borderline.

Is eating fat good for you?

On the one hand, the evolutionary approach underlying many of these diets, whereby humans are not made to eat grains or carbohydrates in general, is totally wrong. Ask an evolutionist if evolution is a linear or a random process. And he will tell you the second. Man is by nature an omnivorous human animal. And according to the new research he fed, albeit occasionally since he did not plow the land, also on cereals, shrubs, fruits and legumes in the Paleolithic.

Another problem is that many studies on low carb diets are selective in the choice of the sample or marginal if we consider both the number of participants in the single study and the observation time, usually short or medium.

Therefore, there is a lack of studies on a non-selective population sample (not related to tribes, for example, or to people with particular diseases) and there is a lack of studies that investigate the effects of a diet without carbohydrates but with a lot of fat over the years. And it must also be considered that many cardiologists disagree with the theory that fats do not raise cholesterol. In fact, most studies say just the opposite.

The cardiologist’s opinion on fats

One of these “against” cardiologists is undoubtedly Dr. Dean Ornish, world-renowned cardiologist, author, popularizer and creator of the Ornish diet for cardiovascular well-being. This diet is considered one of the best ever for those suffering from lipemia and cardiovascular diseases.

Ornis has defended a low-fat diet and increased consumption of fruits and vegetables for decades to keep cholesterol at bay. According to Dr. Ornish, people can’t wait to hear that butter and meat and sausages can be eaten at will without consequences. Too bad that people who say that according to medicine a full-fat diet is the healthiest, do not cite any research appropriately, but only partial data, and this is not out of ignorance, but perhaps out of bad faith. bias, or so-called cherry picking ).

Instead, Ornish cites studies and research that continue to show only one important fact. Those who eat fats in a high percentage have more cardiovascular disorders and a higher risk of mortality from many diseases than those who eat a diet based on a lower consumption of fat and a greater consumption of fruit and vegetables.
