Re: High-fat diet KEEPS you from feeling full? +intestine protection of fats

------> I can't find free access to the actual study but one article

talked about the rats being fed 1/2 lard, 1/2 corn oil for the fat.

The corn oil could be the culprit especially if it's gm corn (very

likely is). These studies are complicated since we know nothing about

the quality of the food and what the rats were bred to do.

-----> The hormone they're studying is called cholecystokinin, or CCK

that tells us to stop eating for awhile after eating a fatty meal.

It's secreted by the small intestines and travels by the blood to the

brain. Evidently with fatty foods the rats became less sensitive to

signals from it. One study said men are more sensitive to signals than

women after eating lots of fats. (course once again what are these

fats??????)

On a side note one article said the rats ate more often but adjusted

their quantities of food. The CCK resistant fat-eatin rats were not

gaining any more actual wieght than their nonfat-eatin buddies.

I do have problems with certain fats leaving me very hungry in a short

period of timebut I'm currently looking very closely at gut damage as

a piece of this.

Bacon and eggs can leave me famished if I don't include some carbs so

I usually ate it with a small slice of sourdough. Butter was

especially bad at making me hungry in a short period of time. Usually

had it on a slice of sourdough Once I ditched bread (gluten) fats are

working far better at satiating me. (coconut oil is the best for this)

Here's an interesting side article I came across on the role of fats

and CCK in protecting the intestine. Goes right along with gut damage

from gluten and why CCK might not be able to work right. It's possible

that fats eaten in a gut damaged intestine cause a large release of

CCK and the body begins to desensitize to it (like insulin resistance)

A new study published in the October 17 issue of The Journal of

Experimental Medicine says that fatty foods can fight inflammation in

the gut. This feature may help the body prevent an autoimmune reaction

where food is taken as a foreign particle.

Fat rich foods stimulate the intestine to trigger the release of an

enzyme called a hormone called cholecystokinin, or CCK. This enzyme is

responsible for digestion of the food and also satiation, a feeling of

fullness that is a silent signal to stop eating. Luyer and colleagues

studied the effect of fat-induced CCK on the gut and found that rats

that were fed with a high-fatty diet were protected from lethal

bacteria, while those on a low-fat diet did not have the same

immunity. The mechanism of action was that CCK sent signals to the

vagus nerve, which in turn triggered the release of a neurotransmitter

called acetylcholine. This bonded itself to the proteins and switched

the immune cells off. The study authors say that this pathway may

explain why the body does not reject food as a foreign invader. They

also feel that it might be useful to activate this pathway after major

surgeries.
