Over at Ironmagazine.com, several users are unaware of recent studies vis a vis meal frequency. Can someone provide me a link to studies showing that lowering frequency does not equate to catabolism or altered metabolism?
(I have found several threads regarding the issue, namely from Lyle, but few documents of lab research)
Thanks alot for the help guys, you know I appreciate it. :D
 
I know there are studies referenced by Aaron, Cliner9er and myself in here, just not sure where at this moment.

Here are a few :)
Although I haven't read them all I have read quite a few in the past and from what I understand here is what you will see. Frequency has little impact on RMR, but a larger impact on satiety. Frequency has little impact on energy intake when free grazing ;) #2 shows there is an impact on Insulin and Lipid Profiles but Aaron could tell you more on how relevant that study was. If after reading those you have questions I am sure Aaron (if not too busy) can help out or CLiner9er and I will help you out if I can. Aaron is your best bet

Hey thanks alot dkm.

Correct me if I am wrong, but it seems alot of these are pro-frequency?
 
Yes in a way because frequency relates to the effect of feeling satisfied, but frequency does not relate to increased BMR or RMR as some believe. Also it's effect on insulin is commonly misunderstood, in the body building world. Tom asked a question a bit ago about frequency and protein from what I have read the frequency of food and it's anticatabolic effect have a ton of side issue that relate to it, Aaron made some good points there, even though he can be curt, he is the man when it comes to nutrition and human metabolism, that's what he is paid to do so he should be. Hopefully he can RE-address the frequency issue if you have any questions. Or better yet do a search on frequency in this forum and see what he has already posted.
 
Ah, I see.
No need for that, the guys over at the Iron mag forum will never believe it anyways. That is, unless muscletec releases the studies on their web site.
At least I tried. ;)
 
in some situations frequency can be good, but magical it is not.

1) fat loss.. some people get increased satiety, so they eat less. This is a function of calories rather than the frequency per se
2) more frequent feedings will lower the overall glycemic response to meals, even if you are eating high GI all day.
3) allows some to eat more food than if they were limited to less frequent feedings

in some situations more frequent sucks
1) this is where the satiety signal gets a bit funny. For some (me included) who have to eat a relatively low calorie diet to get decent fat loss (i sit at a desk alllll day). Basically it means you have to eat less, small meals suck majorly, so less frequent feedings will give a sense of a larger food intake (splitting 1800kcals over 6-8 meals really sucks) 225-300kcal meals. Doing 4 meals a day is far more manageable 450

there may be various health effects of frequency, which can be also attributed to food choice as well.. but it gets messy when looking at a whole diet.

in terms of the studies provided by DKM
1, 2 and 4 are looking at regular meal pattern rather than frequency per se
3 shows no effect on BMR
5 shows no change in TEF
6 = satiety
7 = snacking may cause compensentory effect on other intake, but maybe no in real life
8 = no effect on fat loss, weight loss or rate of each.. something weird with sleeping metabolic rate
9 = nothing stand out:) just what one would expect from it
10= TEF greater after the large meal than the small frequent meals, once again, as it should be
11 = no effect on DIT or others
12 = doesnt seem to talk about frequency, but seeing as they do not seem to use paragraphs , who would know what they are talking about
13 = this is where things start getting messy... its an uncontrolled, non randomised trial showing that elderly people eating more often have better caloric and nutrient intake than those eating less often :) cholesterol breakdown imporived, but seperating those effects out of every other change is a challange.

so over all, no real pro-frequency breakdown of the research
 
Thanks Aaron, those studies you posted are so much more clear and concise.
