    There was a fascinating article in the weekend aust mag this week on Intermittent Fasting — supposedly the latest thing in weight loss fashion. Normally I don’t pay any attention to diet stuff because it simply doesn’t interest me, but this was something different. The basic story is that for two non-consecutive days out of any week you either fast completely or simply restrict your food intake to 2090 kj for women and 2510 for men. Not a programme for anyone who is not already healthy, esp diabetics, pregnant women or anorexics or even people who are already extremely lean, but for the majority of people, quite possible. Lots of benefits, like reduced risk of breast cancer for women and a slowing down of the ageing process, but these are only researched short-term, so no long term data (or risks) available. Hubby and I are going to try one day a week to start and see how it goes. What do you think?

    Mudhen i hope you mean 2090kj not kg :jawdrop:

    not sure how one would consume 2090kg :sick: lol

    when i was younger (violins playing in background) my mother and sister and i used to fast about once a week when we were first trying to rid toxins from our bodies – but our fasting was to eat/drink only fresh products of a particular fruit such as watermelon or grapes for the whole day – later we changed to once ever 4 weeks – we seemed to get rid of alot of the toxins that had built u i our livers :shrug:

    As a cleanse, it sounds good. It would be no good for weight loss, would just mess up your metabolism.

    Sounds like a pretty silly way to fast. After all, fast means no food. Therefore eating anything at all is breaking that fast.

    I fast every day. I don’t eat from about 8ish pm (depending on when dinner finishes) to between 11.30 to 2pm every day. I’m not hungry before then, so no need to eat.

    It’s not really the latest fad but based on our evolution. After all, it would have been more often than not there was nothing to eat until the animal was hunted or the tubers dug, tree found and fruit removed etc.

    It is actually really good for weight loss, if you eat properly when you do eat. Having maccas to break the fast isn’t going to work. Eating meat protein, good fats, vegetables and perhaps a piece of fruit is.

    I’ve been doing this since Aug 2011. Yes it does work.

    I haven’t seen the original article, however I am keen on all things diet (for reasons that have absolutely nothing to do with losing any weight lol)!).

    From Memory, the origin of this diet came from the concept of eating like a lion … eat big, when the food is available, and eat nothing when it’s not. Bit of a feast and famine concept.

    Bron, there’s a fella (muscle bloke) who ate like you (and they called it Intermittent Fasting).

    Anyways, I wouldn’t touch the idea of having restricted calories/kilojoules … ever. But that’s probably because I would faint if I didn’t get enough food (ridiculous metabolism, I’m in that 1% of the population that needs to eat … a LOT).

    But it’s interesting, for sure. Personally, I reckon if you can tune in to your body (I tell my lot that it’s listening to your body), and eat well when you are hungry, it will take you a lot further than any specialist diet (unless that specialist diet is specifically targeted to your body type and metabolism, by someone that knows what they are doing).

    Interesting read in Wiki

    Timeline

    0 hours: Glucose still used as primary fuel.

    0 – 6 hours: Glycogen is broken down to produce glucose for the body.

    6 – 72 hours: Glycogen stores are used up and the body breaks down fatty acids. Ketone bodies are produced to help feed the brain.

    The rate of protein loss is greater during the first 72 hours. After several days of starvation the body adapts and starts to conserve protein.

    also with fasting might it put the body in some sort of panic mode, so anything you eat it turn to stored fat for safety? that is similar in the CFS thing which i have i was exercising following dietician eating all this good looking fruit and vege’s from the stupid market, but i was unaware that the food was considered empty food, that is it had no nutrion that teh body could recognise so it took all carbohydrates and turned them into fat, hence the immune system fails from lack of nutrient.

    then a few year later along come T2 DB.

    never actually heard of fasting diets working, but whatever works hey? reckon one would need to be sure their food was fresh and homegrown.

    There was an article on this in last November’s New Scientist. This one might… and I mean *MIGHT* just have some science behind it. Early days in the research though so too soon to tell if it actually works in people. The premise is that intermittant fasting has a permanent impact on levels of IGF-1 which is implicated in a host of stuff. But.. as I said, too early to tell if it has an actual clinical impact.

    http://www.newscientist.com/article/mg21628912.400-deprive-yourself-the-real-benefits-of-fasting.html

    You need to pay for the article if you aren’t a subscriber unfortunatly…

    Cheers

    What’s IGF-1 Dave please? :shrug:

    That link is a bit of a tease 😛 but I’m sure not paying to read it. I’m a mean old bugger. 🙂

    Haven’t read the article, but remember watching a doco some time back that said that the only proven anti-ageing technique was to remain slightly hungry after every meal. Apparently the longest-lived people the world live by that philosophy, such that they only eat small meals, remaining slightly hungry after every meal. And they live very long lives. I think they might’ve been Nepalese, but can’t be certain now…. :shrug:

    ETA: Just found this article. It might’ve been people in Okinawa I was thinking of… and the 80% rule: Longest-lived people

    Sorry… Insulin-like Growth Factor 1.

    Its a hormone that (amongst other things) moderetes the bodie’s response to food. Its also implicated in a bunch of other stuff.

    Cheers

    And apologies for the tease. I’ll try to find a way to post the text here without bringing the copyright police down on me. If not, your local library willprobbaly have a copy… look or the 17 November edition (No2891) with a cover story of “Climate change – 5 years ago we feared the worst but its looking even worse than that”.

    Oh.. and even mean old buggers should read new scientist. Its good for you.

    Thanks Dave! My computer is playing up and I lost my reply! Will try again.

    Bobbee, the article I read put it this way, IGF-1 is a hormone that keeps our cells constantly active. We need it when we’re young and growing, but in later life if you have high levels, it accelerates the ageing process. If you can drop the levels by fasting, your body slows down production of new cells and instead repairs the old ones.

    Barefoot_Misty, it IS messing with your metabolism, but in a good way.

    Bron, I agree, eating any food during a fast is not technically fasting, but to be fair, not everyone is up for diving in with both boots. There are many different ways to work things out, and your way works well for you, but might not be right for everyone else. The basic premise that I have understood is that to restrict your food intake on a regular basis is a healthy way to live and full-on fasting is not necessary to get the positive results.

    Ma, you have put it so nicely! Unfortunately, having a plan / guide is sometimes a necessary crutch for people who have a hard time getting in tune with the needs of their body. It would be much easier if food didn’t have any psychological impact on us!

    Here’s an article that explains what happens if you don’t have access to this as a child:

    http://www.nytimes.com/2011/02/17/science/17longevity.html?_r=0

    If you get to the end of the article, it explains that researchers have genetically modified mice to have this same condition. The oldest mouse lived to the equivalent of 160 human years, and they are immune to heart disease and cancer.

    You could also watch the video of a BBC documentary made last year by Michael Mosley on this topic:

    I intermittently fast most weekends, although it is normally because I get busy then realise (usually in the afternoon) that I am hungry, then think “oh thats right all I have had all day is a couple of coffees, that might explain why I am a bit hungry” LOL

    But I agree with listening to your body, within reason, if you are craving something then there is probably a reason for it, and it is your body trying to tell you it needs something (not to be confused with advertising trying to tell you you need something)

    Ma, there isn’t restricted calories?? I eat as much as I need, but because I don’t eat simple carbs (or very limited), it is very hard to eat too much. I’m a ‘fat burner’. You feel faint because you’re a carb burner’. Your body realises it has a much easier to use fuel source, but it burns very quickly so you run out much quicker 🙂

    I’m just eating my first meal of the day. I’ve been working, then had to get something from the shops, then wait for the meat to cook. Like you, once, I would have been almost unconscious as my blood sugar levels plummeted. Now, hunger isn’t that all-consuming, desperate need to eat. It’s ‘meh, I’ll get to it’. Even better, I no longer obsess about the next meal. In fact, I can work with food and not even think about eating it. This is SO empowering.

    But yeah, that’s my experience (and the experience of just about everyone who eats paleo, if they get through the withdrawals).
