Protein suppresses appetite

[Analog6]

I saw a precis of this iteresting (but very technical) article (link below) in my newspaper at the weekend. Basically it is saying that diets high in protein trigger glucose production in the small intestine. This in turn makes the liver send a message to the brain saying it is nit hungry any more, and voila!, you're not.

This certainly seesm to be true for me, as I am eating lots of meat and don't have hunger pains since I cut out the carbs with Atkins. My Mum is trying it to lose weight and told me she was still hungry and lethargic. Turned out she was eating mostly veges and littel protein. Since she is havinf more meat /fish /chicken te hunger and lethargy have disappeared.

What are others experiences?

Re: Protein suppresses appetite

your sumation is slightly off

Rats fed high protein diets made glucose through glucogeneses in the intestines which humans have the ability to also do and this was sensed in portal veins and that sensed glucose was relayed to the brain which turned off the chems used to say you are hungry.

But they didn't show any actual humans doing the same and as anybody who has followed promising drug break throughs what happens in the lab animals doesn't always happen in human beings.

it will be interesting to see if they can make their hypothesis stand up in human testing.

Re: Protein suppresses appetite

I know some humans who are rats; maybe they tested it on them??

Anyway, I love my protein, and yes, it certainly fills me up!!!

Re: Protein suppresses appetite

Approximately 58% of the protein we eat is converted to glucose by our body (that's just the way our bodies work.) Excessive glucose is stored as either glycogen or fat. So eating a "high protein" diet can potentially be counterproductive to stabilizing your blood sugars/controlling your insulin response and can potentially be counterproductive to weight loss.

Atkins is a high fat diet. Protein intake is maintained around 30-35% of your total daily calories.

Megs the high is a realtive term and while i can't tell you what this study used another one used the Atkins 30% as a high protein but again it was in lab animals not humans.

Re: Protein suppresses appetite

Yeah, "high" is a relative term because the current recommended protein intake for adult humans is 0.5-0.7 grams of protein per kilogram body weight per day. That's an interesting number because it was based on Chittendon's research from the 1900s that showed humans can live on a minimum of 0.9 grams of protein per kilogram body weight per day. So the current "recommended" protein requirement is the lowest amount of protein you need in order to survive (or go into protein malnutrition). Before Chittendon, the recommended protein require was about 2-3 grams protein per kilogram bodyweight.

It's funny that if you look through early 1900s medical books and articles, they refer to Chittendon's diet as a "low protein" diet---and 100 years later that "low protein diet" is the norm for everyone. What's sad is that Chittendon used healthy, athletic men in their early 20s in his experiments. So it makes you wonder if that number applies equally to other ages and sexes with varying degrees of physical activity and general health.

Re: Protein suppresses appetite

I eat alot of protein, but I also run it off! I've never seen any weight gain from eating my protein. Ever. Protein is essential for protecting and repairing muscle tissue.

Re: Protein suppresses appetite

you'd be surprized how little protein is needed to support and repair a human body andhow much is used as energy

Re: Protein suppresses appetite

If you eat primarily animal protein, then you're also eating fat because animal protein, like a chicken thigh, has fat. For example, 3 ounces of chicken thigh meat has 10 grams of fat and 16 grams of protein. The fat is 58% of the total calories, protein is 42%--because fat has more calories than protein. If you eat 6 ounces of that chicken thigh meat, your fat and protein %s are still 58% and 42%, which still makes it a "high fat" food because the fat is more than 50% of the total calories. If you eat a "leaner" cut of meat, like 3 ounces of chicken breast, it still contains fat, but now the fat is only 37% of the total calories.

It's the caloric percentages of fat, protein and carb that matters for us. That's why you don't need to eat "alot" of meat or fat on Atkins.
