Maribeth, another question for you

Hi I was just re reading the old thread that you made. I have a question about what you said about the protein,carb, and fat thing. Could you explain something about the 20-40% of protein cals being used verses the fat and carbs.I am not sure if I understand what you said. Are you saying that it is harder for the body to store protein verses fat or carbs? Thanks, I hope that makes sense.

Also this is a dumb question, which I am sure I know the answer to. But will you list some foods that are very high in fiber besides beans. Thanks
 
HI!!

I am obviously not Maribeth, but here is my "unexpert" opinion.

I know that protein is harder for the body to store only when the other macronutrients are present in the diet. If you are taking in adequate carbs and fat, the protein you eat will most likely be spared for metabolic processes. Also, in digestion, protein burns more calories...I think they say one quarter of the cals in protein gets burned just to digest. That of course is an estimate, but that means if you ate a 100 cal chicken breast, roughly 75 cals would be left and useable either for reparation or storage as fat. On the down side however, is I also am aware that the body has no place to "store" protein for later use. Therefore, it would seem to me if you took in a great excess it would be inevitable that quite a bit would be stored as fat, assuming you are also taking in carbs....Lets see what Maribeth has to say.......
 
Thanks DebbieH & Colleen

Good reminder. Gets pretty darn specific when you scroll up. I liked the section that summarizes the typical U.S. diet vs a fiber rich diet.

Think I'll go check out the rest of the site.

OK, Maribeth....we are waiting for you.......where are you??????????????????????????????????????????
 
Sorry! I missed the post!

With protein, no matter what your nutritional status, the body will expend between 20 and 40 percent of the caloric value of the protein in the digestion/absorption/storage process. So, if you eat 100 calories' worth of protein, the body will burn between 20 and 40 calories just in the work of digestion and storage. But the body will still digest, absorb and either use the amino acids to build muscle, organ tissue, hair, etc, or break off the nitrogens and use the carbon skeletons to make glucose (if it's needed) or fat.

Now, this isn't a plug for eating a high protein diet at all, just an explanation of one of the reasons why the high protein dieters do lose weight--the higher protein content in their diet means a higher basal metabolic rate, due to the extra calories expended in the digestion/absorption/storage process--vs their typical argument that protein can't be converted to fat. There are definite down sides to eating excess protein.

Still, the bottom line, even with eating protein, is that if you eat more calories than you expend, you gain body fat.

Did this help?

I'm going to check out the fiber website, too. I need some more foods to add to my list--thanks!
