The FastDay Forum

Not necessarily, the 'Primal' approach advocates fasting and high meat consumption http://www.marksdailyapple.com/primal-b ... z2LNlq2SAC
The idea is basically that high fat is necessary with restricting carbs and moderating protein, and is not unhealthy for a 'fat burner'. Still pretty controversial it has to be said.

Just come across this: http://news.usc.edu/#!/article/46944/lo ... s-in-mice/ which adds to the debate about protein intake being a crucial component in all kinds of age-related disease. I just wish they were a little more precise about what 'low protein' means in real terms. Any thoughts?

Hi Caroline,

I'm fascinated by this subject and wondered if you'd seen this youtube video:-

The IGF1 stuff doesn't start until about 18 minutes in, but I'd be interested to know what you think about what he says in general as you seem to have quite an analytical outlook. If nothing else it's quite an entertaining lecture and a bit of an eye opener.

Interesting video for any nutrition geek, seems like a good cross survey of research. Love the way being an MD doesn't stop hjim slagging the medical profession where felt justified. For me I think 52 is easier than a vegan diet would be.

Fascinating and compelling. It's such a shame that eating meat and animal products seems to be so detrimental to health! What strikes me as odd is that we have evolved to eat meat, so why would it be so bad? You have to wonder how much modern farming practices and food processing has to do with the observed high mortality among m meat eaters! Certainly fasting appears to go some way towards mimicking the "vegan" effect.

I think I will try to make more effort to lower my animal based food consumption at the same time as following fasting in the hope that I can eat steak, chicken, roast beef, butter, eggs, milk etc without shortening my life by too much!

I might copy your link to a new thread in resources so that more people will get to view it. Thanks so much for sharing it!

I'm really glad you enjoyed it. It does make you take a step back and think twice about just how much meat we eat. Although I failed miserably at becoming Vegan I have dramatically adjusted my proportion of animal protein to veggies and fruit. I think the general consensus is that keeping animal protein below the 20% level makes a real difference.

Hi all,I have been doing 5:2 since the end of March and so far I have had an approx 2kg loss which I have kept off but have jumped up and down within. I would love to lose another 2kg but I am not sure how realistic that is seeing as I haven't weighed as little since late high school! Plus I know I overdo it a bit on non fast days

Anyhow, the reason for this post is that I recruited a friend of mine to start 5:2 yesterday and sat down with her and watched the Horizon doco again. It's really interesting to re-watch it and it reminded me that apart form the aesthetic affect of losing weight (and associated health benefits of course), that one of the reasons I started this was the potential reduction/drop of IGF 1.

My friend noted that Michael Mosely, in addition to cutting his cals on fast days, ate better on "feed" days and exercised more. What I wanted to know is that with the huge range of ways people have implemented 5:2 (which may or may not adhere strictly to optimum nutrition on feed days and more exercise generally) have people (who have measured) had the same successful reduction in IGF 1?

I understand it is quite expensive and difficult to have this test done on request in NZ and this may be the same in other countries. But I was wondering if those who have had done this test could share their results somewhere on the forum so they could be collated?

Maybe this is something which has already been done but I couldn't easily find it on the site.

Cheers for your responses

Very good question - look forward to any other comments.

I would also like to see if some one/organisation is conducting ongoing research on this topic since there are now so many people following the 5:2 WoL. I am of course aware that human studies are extremely difficult and must admit that I myself am not too keen to be fed by a researcher over the next 30 years but would be willing to submit to tests and questions on 5:2 WoL questions periodically.

It's around $70 in NZ and should be able to be done at any pathlab and can be self referred - the test needs to be sent to a place in the South Island as there is only one lab in NZ who can perform it as far as I know. So it's not too hard to get done and not too badly priced I thought... Haven't done it myself but may do it in the future as it was a main reason for me to start too
