Dig a little deeper into the functionality of Leptin. It also regulates your energy expenditure (BMR).
Do you have some peer reviewed studies to share? Where did you get your information?
A google search of leptin just gives me a whole lot of blogs telling me to reset my leptin levels.

Yes. Here is a article that explains Leptin in terms of weight loss: http://www.bodybuilding.com/fun/sclark60.htm

Unbelievable to read some of these responses. Ignorance combined with arrogance is a dangerous thing.. OP is accurate regarding Leptin...

Lol! I admit I skimmed (because I really don't care). Personally I think it all comes down to wanting easy fixes and lack of willpower to sticking to calories (both for loss and maintenance). If Leptin levels or Leptin resistance was truly an insurmountable thing gastric bypass wouldn't work, and people who have dropped 100 pounds wouldn't have made it that far in their loss before the "Leptin reaction" kicked in and stopped their loss, then caused gain.
But of course it's never that anyone made a mistake, we "know their logging is 100% accurate and perfect"0 -

Yup! Except Leptin (which the few actual medical research I found all agree on) is created by fat cells, so it doesn't matter what you eat, unless "you're" increasing fat cells "you're" not raising Leptin levels. Which means it's nothing more than a gimmick to make money off of.

Except I'm not aware of studies confirming this belief of reduced BMR from a reasonable deficit (and not just a reduced BMR from the reduction of overall weight itself). Sure, many have found a re-feed day helpful in adherence to an otherwise overly large deficit, but not that it affects BMR in any meaningful way.
I'm not saying the belief isn't out there...it certainly is...everywhere you look (and, of course, by those selling you the idea), but the science that I'm aware of (and my own personal experience of daily logging for three+ years) has not yet demonstrated the belief is valid.0 -

And yet without any control and experimental groups along with proper monitoring, you cannot know that this is why... Or that they don't even plateau. For all you know they are also increasing their cardio while decreasing calories without refeeding.0 -

You are missing the point. Leptin is created by FAT CELLS, therefor the only way to increase Leptin levels is to increase fat cells (aka GAIN weight). A day or two of "re feeding at maintenance" is not going to do that. Secondly the age of the study doesn't change the basic science, your "study" is the only one that says obese people have low Leptin levels all the others I've found state during testing Leptin levels on obese people had HIGH Leptin levels.

I don't think those referenced articles prove what you think they prove...at least not for humans. They're certainly far less certain in their conclusions than you are in your post about them.
And I still maintain that perceived success from re-feed days is more likely explained by better adherence to an overall caloric deficit than it is from some effect on BMR. BMR is simply very difficult to affect...especially over a relatively short period of time.0 -

Not really, since the peer-reviewed article (bodybuilding.com isn't an academic journal) doesn't mention the words calories, refeed, basal metabolic rate/BMR anywhere in the text. There are two studies referenced wtih the word basal in their title.jofjltncb6 wrote: »Amanda4change wrote: »Leptin

Sounds like it isn't 100% if it actually "speeds up metabolism" or not.
Dig a little deeper into the functionality of Leptin. It also regulates your energy expenditure (BMR).
Do you have some peer reviewed studies to share? Where did you get your information?
A google search of leptin just gives me a whole lot of blogs telling me to reset my leptin levels.
Yes. Here is a article that explains Leptin in terms of weight loss: http://www.bodybuilding.com/fun/sclark60.htm
And here is a peer-reviewed article: http://www.jci.org/articles/view/45888Our current understanding of leptin action on energy balance is largely based on animal research and, therefore, one may wonder how much we have really learned about leptin action in the human brain
It sounds like they don't really know either. That's from your peer reviewed study.
According to OP's "study" obese people have low levels of Leptin, yet according to this study (as well as others) Leptin levels are HIGH in obese people: http://www.ncbi.nlm.nih.gov/m/pubmed/17212793/
Those were studies done 6 years prior to the one I posted. The study of Leptin is still relatively new. Also, if people here are coming for confrontation, you are not going to find it. I do deserve the ridicule for my mix up of hormones because it was a careless mistake, and I apologize. I came across Leptin because I've been researching the reasoning by why some people are able to reach very lower body fat percentages with virtually no plateaus. They do this with a caloric deficit with consistent re-feed days to boost metabolism back up due to lower Leptin levels, which reduce BMR.
Except I'm not aware of studies confirming this belief of reduced BMR from a reasonable deficit (and not just a reduced BMR from the reduction of overall weight itself). Sure, many have found a re-feed day helpful in adherence to an otherwise overly large deficit, but not that it affects BMR in any meaningful way.
I'm not saying the belief isn't out there...it certainly is...everywhere you look (and, of course, by those selling you the idea), but the science that I'm aware of (and my own personal experience of daily logging for three+ years) has not yet demonstrated the belief is valid.
I sincerely appreciate your non-hostile response. The article I posted: http://www.jci.org/articles/view/45888
and
http://www.bodybuilding.com/fun/sclark60.htm
talk about Leptin levels affecting your energy expenditure
"Since its discovery, leptin has been found to have profound effects on behavior, metabolic rate, endocrine axes, and glucose fluxes. Leptin deficiency in mice and humans causes morbid obesity, diabetes, and various neuroendocrine anomalies, and replacement leads to decreased food intake, normalized glucose homeostasis, and increased energy expenditure."
I was always fascinated on why people were getting such great results with re-feed days. This is just the science behind it.
That's it.
