10 months for body to "reset it's memory" Fact - or myth?

[Huseyin]

I certainly can tell KD its a huge passion of yours yes lol. Now i know where to come lol

Still its good somebody has taken the time to research it for us on here, im greatful for that

[KD]

I have a few passions

They say that successful maintainers who have lost lots of weight, often make weightloss issues a lifetimes work. This think this often is the case.

I for one became a CDC (eventually), moderate a couple of dieting forums, but my passion is really in researching dieting myths.

Icemoose has also gone much more into the whole 'mindset' of dieting, qualifying as a NLP coach (Master?) and writing a book about it.

Even our Porgeous has seemed to have put her passion into the clothes side

Interesting I think

Anything that helps people keep it off after a lifetime of struggle is worth it.

Interestingly enough i know a man (friend) who has trained with Paul Mckenna and i quizzed him about the "i can make you thin" TV show, apparently it has a 70% success rate, that is something worth looking into as well especially since its logical, eat slowly and consciously that is the message, chew your food 20 times before eat swallow.

So yes i can see how it influences people, its make me more aware of dieting issues and its certainly interesting indeed.

Though I believe in many of the techniques PMcK uses, I don't believe the 70% success rate.

Not enough proper scientific evidence. Not been doing it long enough for a long term study. His word against the scientists. He is a great salesman though...give him that

And, as I say, many of the techniques that he uses (which mainly aren't really his techniques!) are good practice for a lot of folk.

I attended a education evening for GP's and the medical profession held at the hospital where I work. A professor in obesity who works in the NHS and runs obesity clinics was due to give a talk, but unable to attend, so his registrar took the talk. Although a lot of it went directly over my head as it was very scientific, he mentioned this drive, and it's driving me mad as I can't remember either his name or the what he called this drive!!

Anyway, he said it took 6-12 months until your body was no longer driven to get back to your highest ever weight and the setpoint was reset.

I know that my post is probably actually pointless now, as KD has comprehensively answered this question already, but thought I'd let you know anyway as it was interesting to me to hear somebody obviously very qualified state this point that until now I also thought was a bit of a "they say" point! ;-)

[Huseyin]

Yep we have Prof KD on the case

KD yeah the say 70% but we shall see he certainly is a great salesman especially when he promotes those figures and tells you where you can buy the book shortly after

[KD]

Yep we have Prof KD on the case

LOL

Being a bit of a science geek I do not go by books at all as they are never peer reviewed. I will search PubMed when am at Uni tomorrow and see whether I can dig up any journals with good hard evidence. My opinion is anyone can write a book, anyone can carry out a scientific experiment but very few people can get a journal published.

There's some on pubmed. One of my first calls, but I didn't find anything about the time frame. There's a fair bit about body setpoints, but that's established anyway.

And anyway. I didn't go out and buy the books, then think "hey...fancy that". I read the 'journals' then decided to buy the books. Okay...happened to have a couple of the books anyway as they had other things in them that I was looking up for something else

[KD]

BTW, did any of you watch the horizon programme about it a few weeks ago. Was interesting

KD, see to me it is a simple equation. If you work hard at keeping the weight off for a long time i.e. a year or two the probability of you putting it back on is greatly reduced as it is proof you have altered your life style. That doesn't need any scientific backing as it is just common sense. Since every human is individual it is impossible for anyone to set a time frame for it, it may take one individual 3 months to alter their lifestyle and adapt to it and another 36 months.

That's what I said But I think BL was asking if it takes 10 months, and someone else suggested less.

This could well be to do with the bodyset. That would fit in well. But it could also be a change of habits etc.

That's the trouble with dieting research. It's incredibly hard to get definite answers as there are just too many variables.

My interest for the last 2-3 years has been in the area of leptin, insulin and ghrelin and it's effect on the body setpoint, rather than for how long. Which is why I can't answer that bit

But you think you will find it on pubmed. Good luck

[Bijoux]

Insulin is released into your blood stream after you've had a meal to mop up the excess glucose so how can it affect your appetite or body set point?

I will search the different journal databases to see what I can find, just to satisfy my own curiosity.

It does more than that. The main hormone is leptin though. Basically leptin tells the brain your size. On overeating, adipose stores get bigger and more leptin is made in the fat cells.

Leptin then tells the brain how big we are, how much we've eaten etc. The brain then tells us what to do about it..ie, eat more, eat less, stop eating.

Unfortunately the more fat you have, the more leptin you have, and the more resistant you can become.

The pancreas will produce more insulin, and resistance then builds up with that. It's easier to control the insulin with healthy foods. Not so easy to control leptin. Leptin is the biggy

Much more complicated than that though, and it really involves many dozens of hormones.

Do a search for leptin, insulin, ghrelin. It's really interesting.

I wrote a bit more about it on here a couple of years ago, but don't want to search....gotta headache

[Bijoux]

I will do. I know that insulin cannot affect your appetite so I was just wondering what that really means, I know if you develop Type II diabetes you are more likely to be obese but this is because your body is not very effective at taking up glucose so it stores it as fat.

As for the other two, there's alot of information on them however they were discovered in the mid to late 90s so there's many contradictory journals. I have however been reading about leptin and it is a life-time problem per say in people with the supposed homozygous gene that codes for this protein hormone, people with this gene always have the desire to eat. I have also read that at different stages of your life you have different levels of leptin so in essence the leptin level can be altered when you change your lifestyle. Leptin's action is co-dependant on ghrelin and vice versa, leptin is produced by adipose tissue so essentially a decrease in adipose tissue reduces the amount of ghrelin and leptin produced, that's my understanding. Unless ofcourse you have been obese for a good proportion of your life and have developed resistance to leptin. What do you think?
