Why do people assume a ketogenic diet has to be high in saturated fat??

OBJECTIVE:

To determine the effects of a 24-week ketogenic diet (consisting of 30 g carbohydrate, 1 g/kg body weight protein, 20% saturated fat, and 80% polyunsaturated and monounsaturated fat) in obese patients.

RESULTS:

The weight and body mass index of the patients decreased significantly (P<0.0001). The level of total cholesterol decreased from week 1 to week 24. HDL cholesterol levels significantly increased, whereas LDL cholesterol levels significantly decreased after treatment. The level of triglycerides decreased significantly following 24 weeks of treatment. The level of blood glucose significantly decreased. The changes in the level of urea and creatinine were not statistically significant.

All 83 subjects received the ketogenic diet consisting of 20 g to 30 g of carbohydrate in the form of green vegetables and salad, and 80 g to 100 g of protein in the form of meat, fish, fowl, eggs, shellfish and cheese. Polyunsaturated and monounsaturated fats were also included in the diet. Twelve weeks later, an additional 20 g of carbohydrate were added to the meal of the patients to total 40 g to 50 g of carbohydrate. Micronutrients (vitamins and minerals) were given to each subject in the form of one capsule per day.

Changes in these parameters were monitored after eight, 16 and 24 weeks of treatment.

Changes in these parameters were monitored at 8, 16, 24,32, 40, 48 and 56 weeks of the treatment

All 66 subjects received a ketogenic diet consisting of less than 20 g of carbohydrates in the form of green vegetables and salad and 80???100 g of proteins in the form of meat, fish, fowl, eggs, shellfish and cheese. Polyunsaturated and monounsaturated fats (5 tablespoons olive oil) were included in the diet. Gradually, the amount of carbohydrate is raised from the original 20 to 40 g in order to supply sufficient glucose to sustain the cells with few or no mitochondria such as erythrocytes, cornea, lens, renal medulla and leukocytes.

Recommended food Fish Tuna, Sardine, Prawns, Shrimps. Lobster

Meat Kababs, Sausages, Minced

Poultry Chicken, Eggs

Cheese Full fat cheese

Vegetables/Fruits Spinach, Watercress, Eggplant, Parsley, Mulberry, Coriander, Mint, Artichoke, Okra, Cabbage, Mushroom, Avocado, Leek, Carrot, Radish, Celery, Cauliflower, Green pepper, Lettuce, Cucumber, Tomato, 10???15 olives/day, Lemon

Strawberry-6/day, Avocado Berries-10/day

Oil Olive oil (5 tablespoon, added to the salad Flax seed oil

I'm earning my PhD in Health Psychology!!!! I mean, I've used an article from 1912 but that was for history sake. Some of my professors actually calculate the average year of all your articles together and if it is more than 5 years, they make you go back and add. Besides, I can't take every article at face value and wait for something to invalidate it. Think about Freud's theory. His theory is used for children and no one says anything. But Freud never examined children! An entire theory built around rich, middle aged women is used to explain the behavior of children...smh

Not sure if different fields differ on this, but in health psychology the age limit is at least 10 years.

I never said that the current article was invalid. I just asked if there was there a more current one. I just know that every time we go up against or thesis or dissertation committee, we have to explain why we used articles more than 5 years old. shrugs I'm not going to apologize for the scientist in me asking for a more current article. I can't turn the switch off sometimes lol

-1, I agree with Matt. Old research can't be invalidated simply because it passes its' 5th birthday.

The results don't change as a research article ages though. Take it for face value until a new result invalidates it.

I am not saying that an adult needs the same, but neither are unhealthy in any way.

The main fats in both are palmitic and oleic, and in very similar ratios.

Bacon fat is very close in fatty acid composition to breast milk 1) Can you prove that statement is true? 2) So what - breast milk is ideal for an infant - why should an adult eat the same macro nutrient ratios as an infant?

Ketogenic diets don't have to be saturated fats. In fact animal fat is generally less than 50% saturated anyway. Bacon fat is very close in fatty acid composition to breast milk. Avocado, olive, and macadamia all have high mono omega-9. But eating a ton of omega-6 is not healthy, whereas saturated fats are more stable.

I have MS, and would like to try the Ketogenic diet but while reducing saturdated fat (I like Swank's reearch and know Wahls is a fan of sat fat. To be on the safe side, I'd prefer to cut down on sat fat.)  Can anyone point me to a recipe book with recipes of how to do keto with other types of fats besides saturated? Thank you!

Ketogenic diets don't have to be high in saturated fat, (old school ketogenic diets for kids with epilepsy typically are loaded with mayonnaise and sugar-free, alcohol free eggnog, all high in PUFAs) but now we know that PUFAs are inflammatory so we try to avoid them.

no one who has researched ketosis assumes that ketogenic diets have to be high in saturated fats. MCTs are far more efficient at inducing ketosis.

Do you have a more current article? Even in research, we don't like to use articles more than 5 years old because it doesn't represent the current scientific findings. This article is 9 years old.
