The continuing thread for those of us following the 5:2 fast or other forms of fasting such as 4:3, ADF, or daily 16:8.
The 5:2 diet was featured on Horizon in August 2012 and essentially requires you to fast for 2 non-consecutive days per week. The other 5 days, you can eat normally - or approximately your Total Daily Energy Expenditure (TDEE - see explanation below). 4:3 is the same except you fast on 3 days in the week. Alternate-day fasting (ADF) is just how it sounds; you fast every other day. 16:8 is another form where you stick to only eating in an 8 hour window each day, therefore fasting for 16 hours each day.
By "fasting", we mean that we keep our calorie consumption very low, around 500 calories on average for a woman, 600 for a man, on those days.
You'll find on these threads we use a number of acronyms. If you're new to the threads, or Mumsnet in general, they might not make much sense.
WOE/WOL = Way Of Eating/Way Of Life. We use this term instead of "diet" as many of us see this as something to do in the long term.
MFP = My Fitness Pal, a website or app many use for keeping track of the number of calories they're eating.
TDEE = Total Daily Energy Expenditure, quantifies the number of calories you burn in a day. This measure is best estimated by scaling your Basal Metabolic Rate to your level of activity. TDEE is critical in tailoring your nutrition plan to desired fitness goals. Here is a link to a calculator to help you figure out how many calories you should be eating in a day.
NFD = Non fast day
NSV = Non scale victory
Michael Mosley has a website to accompany his book on the subject. Please go check it out, as he's the whole reason most of us are here!
Lurkers and new starters: please just jump in and post - you'll find a lot of support here and we’re a friendly bunch.
Here is a list of links to get you started with this way of eating. Please let us know if you find a new article or some other information online:
All our previous threads can be found by browsing through the fasting section of the site.
Another thread which breadandwine has started is a good resource for some of the tips and links that get lost in these big threads. In addition to sharing links, we try to condense some of our top tips for fasting there. Keep in mind, we all do this differently, so these are just tips, not rules. This might be a good place to catch up with us if you're feeling a bit lost!
eatriskier’s thread has some lovely inspiring stories which are worth checking out if you want some motivation to get started or keep going through a plateau. Please add your own too.
frenchfancy has a recipe thread over here, please post any low-calorie recipes there so they don't get lost in these bigger threads!
If you've been at this a while and are moving on to maintaining your goal weight, there is a thread here to discuss that.
Here is the link to the BBC article regarding Michael Mosley's findings, which was featured on Horizon - link to that programme here.
A blog post here gives some of the scientific explanation for why this way of eating helps you to not only lose weight, but improve your all-around health.
This link nicely demonstrates that there are many body ‘right’ body shapes and types, because what we are actually aiming for is low body fat for fitness and health.
A Telegraph article which comments on the diet and gives a brief overview by Dr Mosley himself, very informative if you're just starting. (I highly recommend this for an overview)
A study discussed here gives commentary specifically addressing the effect of this diet on obese people (both men and women), with regard to both health and weight loss. ("After 8 weeks of treatment, participants had an average 12.5 lbs reduction in body weight and a 4 cm decrease in waist circumference. Total fat mass declined by about 12 lbs while lean body mass remained relatively constant.) it also mentions "Plasma adiponectin, a protein hormone that is elevated in obesity and associated with heart disease, dropped by 30%. As did LDL cholesterol (25%) and triglycerides (32%).")
Something to consider if you are currently your ideal BMI: this appears to suggest the benefits for women at a lower BMI might not be seeing the same health benefits that are found on men at their ideal BMI. (Though anecdotal evidence from these long-running threads may suggest otherwise…)
A BIG THANK YOU to all who have been contributing. Most of us are learning this way of eating as we go along. All of the links above have been posted by others in our previous threads, and they've been very helpful.
A HUGE THANK YOU to Greeneggsandnicht for putting together all this info and resources into one concise OP text, much appreciated by so many 5:2ers!
Come join us, and tell us about your experiences with this way of life!

Me too buttered I can't wait to see this WOL work

ToffeeOwnsTheSausage · 01/01/2014 16:49

WhenShe - it was surprisingly easy to make (I am getting more confident to try new things but am still surprised when things work!) and is very nice.

BsshBossh · 01/01/2014 16:56

Welcome mummytowillow. Ready soups I enjoy most on FDs are Covent Garden and Waitrose Love Life ones.

WhenSheWasBadSheWasExhausted · 01/01/2014 16:59

earslaps I'm glad Jillian is working for you. I just got the shred for Xmas, not sure when I'm going to find time to do it. Maybe I'll have more time in Feb.

toffee I think I may have to give it a try.

I've had about 400 cals now, feeling hungry but not too bad. If nothing else this has made me realise just how much I was eating. I had 9 months of pregnancy so I ate what I wanted and 9 weeks of breast feeding so I still ate what I wanted mostly dark chocolate

I think I will struggle to come in under 1000 cals (mil has made a cheesecake bless her).

BigChocFrenzyAteYourReindeer · 01/01/2014 17:37

Cholesterol:

Latest science suggests:

  • high cholesterol is mainly a risk factor for a small minority of people with a genetic condition of ultra-high levels
  • for men it is only a risk factor if they already have heart disease
  • it does not seem to be a risk factor for most women (excluding the genetic ultra-high group), particularly post-menopause.

BUT, many doctors are still fixated on:

  • measuring cholesterol, because it is easily measurable and
  • prescribing statins, because most people won't do lifestyle changes.

However, studies showing the benefits of statins are mostly financed by the manufacturers, whereas studies of people actually taking them suggests they may just increase the risk of dying from other diseases, such as cancer.

I'm reminded of how long it took for doctors to catch up with science and accept the dangers of automatically prescribing HRT, as they used to. Now it is only at real need.

Controversial ! Anyone like to offer their opinion ?

Stupid question alert Confused
I stopped eating today at 2pm, don't feel great and not hungry. So if I didn't eat again til 2 tomorrow, would that be considered a 24 hour fast? And at 2pm could I then treat it as an nfd? I would like to do it as a 500 cal day though if possible to give myself a kickstart.

BigChocFrenzyAteYourReindeer · 01/01/2014 17:55

mrsf

My sugary junk Frenzies started a few years ago, a boomerang effect after ending years of hated low carb - shows the danger of non-sustainable WOEs !

5:2 has changed my Frenzies: from 100% sugary crap to huge amounts of ok food plus 2 -3 crappy treats. Also, Frenzies are now less frequent.

MrsFlorrick · 01/01/2014 18:02

Sorry Bigchoc. Blush I didn't mean to imply you eat crap. It was the high calorie consumption partBlush sorry!!Thanks

My FD turned into a mini fast. I couldn't help but have some pear crumble I had made for dCs and DH. So just about 1000 cals for today.

I don't feel bad though as I certainly did not expect to fast today not even a mini fast. I had prepared for gorging on cheese to cure a hangover. So it's all a bonus.

Plus roast chicken and veg was magnificent!! And the crumble was ridiculously delicious. Grin

BigChocFrenzyAteYourReindeer · 01/01/2014 18:05

No prob, MrsF, I ate crazy amounts of crap before 5:2 !

Not2b
I think some folk do 24hr fasts, then break the fast with a moderate supper, not a binge, followed the next day by a normal NFD at TDEE.

Others, like me, start after supper, then have 24 hrs plus the following night, so about 36hrs on 500 cals.

YMMV. Start with 24 hrs if this easier, or go for the 36 hrs if you are not very hungry.

MrsFlorrick · 01/01/2014 18:06

Not2be. Yes that works too.

If you plug it into MFP it obv won't show "properly iyswim.

Mumrose · 01/01/2014 18:07

Marking my place
A lot to read about 5:2 yet. A bit confused about 16 hours fasting and the 2 fasting days. Is 16 hours fasting on the same days that we fast? Mostly cook indian food at home so need to work out calories etc. weighed myself yesterday 5.7and 242 pounds... ConfusedSad A depressing size 22SadSad

MrsFlorrick · 01/01/2014 18:09

Bigchoc. It's interesting that low carb made you binge.

How many years were you LCing??

Interested because I tried it for 6 months before 5:2. I didn't lose much weight but it did teach me to live without sugar and cut out junk and crap for the most part. Most of all it taught me to stay away from biscuits.

Perhaps it would have been different if I had followed it for years?

MrsFlorrick · 01/01/2014 18:14

Mum rose. Welcome Grin

16:8 is not essential. You don't have to do that. You can just stick to two full 500 cal fast days per week.

I'm a wimp. So I didn't think I could do a 500 cal fast so I started doing 16:8. That is 16 hours out of 24, no eating. Essentially no more eating after dinner then no breakfast and then eat lunch and dinner.

I found it less harsh than two full FD. I lost 10lbs in 3 week doing just that.

Don't worry about your stats. It will all change quickly. If you have a fair bit to lose, you'll lose faster initially anyway.

Not2bObvious · 01/01/2014 18:21

Thanks BigChoc, mrsF
I normally start from supper time, then eat at lunchtime the following day and use my 500. I think I'm going to take advantage of feeling like muck to not eat/not drink alcohol and get a much needed early night! My gut feels completely bound upSad Have work tomorrow and would love to be in a better state in the morning, so I can do a Davina or a quick run. It will be interesting to see how this works out as it would mean I'd have added a few extra hours to my fasting time, might make the difference and help me shift this bloatey feeling.

WhenSheWasBadSheWasExhausted · 01/01/2014 18:46

bigchoc it's interesting 5:2 stopped your frenzied eating. I've always been a bit of a binge eater when it comes to chocolate. I have a really sweet tooth and once ate 12 creme eggs in one go Blush

Oddly enough before my kids came along my bmi never rose over 23.

I have gone over today, 1100 cals but that's just an estimate - mil did the cooking. I need to stop eating now till tomorrow.

BigChocFrenzyAteYourReindeer · 01/01/2014 18:52

Mrsf I low-carbed for about 8 years. It immediately stopped the horrid ulcerated throats I kept getting, caused by very high sugar junk.

I never liked it, but kept on to avoid the throat bugs. However, after several years, I was adding 3,000 cals of cheese and nuts daily, to compensate for hunger / lethargy / headaches.

This coincided with the menopause, during which I found low carb no longer worked to maintain weight, so it may have been partly hormonal.
I was also craving lots of fruit, which maybe was my bod notifying me that it was not getting the right nutrition for this massive hormonal change.

I think cutting out any normal food group is probably unsustainable longterm and will cause boomeranging, as well as nutrient deficiency.

5:2 works because the restriction is only for a day at a time. Then we eat what we want, just don't binge.

You do my head in.
You have been ill. Your DH has been ill, your kids have been ill.
And then you post a recipe that makes me hungry even though I'm full Grin
xx TiP

BsshBossh · 01/01/2014 19:17

WhenSheWasBad though I've never been a binger as such (even at my heaviest) I was a controlled over-eater. 5:2 has stopped that completely, in a way that even 12 months of good old-fashioned calorie counting never could. 5:2 re-sets our digestive systems I think...

Mumrose welcome! I was once size 20. Am now hovering between 8 and 10 after two years. Be patient, be consistent and you can do it!!!

Sorry TiP. I saw you telling me off in TIO and my heart was pounding waiting to click on here to see what I had done Grin.

I am fat. Tired. Fed up. Scared to leave the house. And wondering how to sabotage DH going back to work tomorrow.

BigChocFrenzyAteYourReindeer · 01/01/2014 19:57

Toffee This is a support thread. We would never tell you off, or anyone else.

You need a bit of support at home, until the kids restart school. You can rest more when everyone is out from underfoot .
As your DH has been ill, could he take Thur-Fri as sick days, to also recover fully himself, or doesn't his work really allow this ?

WhenSheWasBadSheWasExhausted you don't 'find' time to exercise, you make time! Smile

Seriously- the benefits from exercising are so great that it should be same priority as cooking, cleaning, MNing etc. Since starting exercise I have so much more energy I can get way more done, so the time pays for itself iyswim.
