The 5:2 thread number 36
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 TDEE calculator to help you figure out how many calories you should be eating in a day.
NFD = Non fast day
NSV/LSV = Non scale victory/Lifestyle (change) victory

Other links
This is a BBC article regarding Michael Mosley's findings, which was featured on Horizon - link to that programme here.
This Telegraph article comments on the diet and gives a brief overview by Dr Mosley himself, very informative if you're just starting.
This blog post 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 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 article 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!

Thanks . I'm fasting today . Going to go and get some veg and make soup while ds is at pre school . Smile

Tiredemma · 10/02/2014 08:46

right- so I think I am doing it all wrong- what an idiot.

I joined MFP mainly because I wanted to record my calorie intake- MFP also gave me a calorie target of 1200 cals a day.

So I have been doing 5.2 and a reduced calorie 'diet' of 1200 which I now understand to be counter productive.

Are you all eating well up to your TDEE on your NFD? I put my details into the calculator and based on my activity etc it says I should eat 1840 cals on a NFD- this just seems like such a MASSIVE amount.

I need to read the book again I think to get back into the 'science' of it all. The sensible part of me understands that I need to eat a reasonable amount of calories in order to 'function'.

I realise that I should either just do MFP with 1200 calorie intake OR do 5.2 and eat my recommended Cals on a NFD - but not (as I have been doing) mix both up.

tiggermummy70 · 10/02/2014 08:57

tired: I'd add another consideration. eat to tdee -20% def not 1200 most people do not loose doing that.

frenchfancy · 10/02/2014 09:00

tired Yes to TDEE on NFDs. Or As I prefer TDEE -20% on weekdays and TDEE +20% on weekends.

Tiredemma · 10/02/2014 09:01

Thanks tigger-
I do an exercise DVD each night (either Shred or Davina McCall)- would you say this is 'Moderate' Activity or just 'light' because its only Dvd?

almostthereagain · 10/02/2014 09:49

Happy now belated? b'day lily & well done bish Emma I do same as french & it's working for me.
I'm fasting today postman Last 2 this week before my holiday, hurrayGrin

PoppyOzday13 · 10/02/2014 10:19

Ok, watching the ice skating has inspired me to do 5 mins on the exercise bike before dinner on a feast day yay!

zedzedzed · 10/02/2014 10:30

Morning all! It's taken aaaaages to read up to date and all I can say is; EVERYBODY GET WELL SOON! (((hugs)))

So, 3 days living on a building site at our new house with two babies under two, crazy or an adventure?

Well, a bit of both.

Add in the howling gale force winds, broken windows and inches of filth and it's edging towards madness, but top it off with raging colds/flu and a 5hr cleaning session with neat bleach just to make the bathroom use-able and it's over the top into insanity.

When I finally managed to bath ourselves and our poor filthy babies at the end of day two, there was a brief moment of warm, cosy, cuddling bliss, sitting in our gorgeous Victorian living room with two happy babies on my knee (one of whom had just said 'I love you so much mummy') ...when the baby projectile vomited all over ALL of us. Nice.

Food-wise, as expected but for the first time EVER I went over my huge TDEE...by 500 on the first night (fry up lunch and then Chinese takeaway dinner...which I only managed HALF of!!! But then quite a few single malt whiskies for pre-bed warming purposes) The rest of the weekend I was ON TDEE which gives me only a 5,000cal deficit last week instead of my 7,000 goal. Not too bad though.

We're all pretty poorly still today, snot and coughs and banging headaches. Don't all shout at me but I'm going to try a fast as I'm not hungry at the moment anyway, but will see how I go and have some soup later if I'm struggling.

Hope we're all better soon, and good luck all Monday Fasters. XXX

Breadandwine · 10/02/2014 11:13

Oh, zzz, I really feel for you! What a nightmare!

But kudos to you for your wonderfully positive outlook! Star

About fasting - listen to your body and pamper yourself where you can! Flowers

BetsyBell · 10/02/2014 11:17

zed Huge hugs to you, what a nightmare Flowers. I'm feeling better now but I did learn something important last week: don't fast when you feel unwell. Eat but keep it as nutritious as you can - your body needs a regular flow of nutrients and energy to get you well again xxx

zedzedzed · 10/02/2014 11:38

Cheers guys. Thankfully we're not nearly as poorly as some of the other people on here, truly horrid....I didn't even know Scarlet Fever still existed!

I'm not really fasting, I just seem to only fancy Lemsip, hot tea, a couple of spoons of Manuka honey, I'll maybe manage some thin soup later as my throat's killing me and lumps are out, (so hope this doesn't turn into tonsillitis) and if that comes in at under 500 then at least it's a FD out of the way. If it feels too hard I'll eat up...promise!

BigChocFrenzy · 10/02/2014 12:36

Tiredemma TDEE and the effect of exercise vary a lot between people. Also, most folk seriously over-estimate exercise intensity / real duration.

So, I recommend you set your TDEE to "sedentary" and then do eat up to it over the week, but create a deficit for the weekend, like frenchFancy advised.

After say 3 weeks, you can adjust the TDEE up or down, according to whether you are stalled or losing too fast.

Tiredemma · 10/02/2014 12:38

Thanks guys- at last weigh in (last week) I had lost 6lbs in total since jan 6th so it is coming off reasonably well- but just worried long term that im going to end up 'stuck'.

ErrolTheDragon · 10/02/2014 12:39

Hello all - FD for me, will be LOF till dinner time. Shredded and got recalcitrant dog as far as the post box, but that wasn't an exercise walk - I went at his stop-and-sniff-everything pace to remind him that he likes being out.

Wonder if the manuka would do anything for rosacea? I'd have to hide it else DH would eat it.

BigChocFrenzy · 10/02/2014 12:39

Zed Do not even try to fast, so NO calorie counting. Your body definitely needs nutrients to repair itself and fight off your lurgy, so have plenty of soup and warm drinks, with milk if you like that.
Eat some stew if you can manage.

I hope you recover very soon.

BigChocFrenzy · 10/02/2014 12:41

That's good progress, Bish

OP posts:
BigChocFrenzy · 10/02/2014 12:45

Zed Try to cut out any sugary stuff, even home-made, as this can weaken your immune system. And no more alcohol until you are well
Sad .

Tiredemma · 10/02/2014 13:05

Ok- just fiddled around with my TDEE- will take off the 20% as suggested on here on NFD and see how it goes

Tnanks for the advice

zedzedzed · 10/02/2014 13:07

Thanks BCF booze right now would be killer. Baby just projectiled everywhere again, so am putting on 3rd laundry of the day.Am drinking lots of peppermint tea, but really can't face anything like stew. Maybe soup and bread later...once the memory of what I just cleaned up has faded!

tiredemma all sounds like great advice to me...1200 can't be enough logterm if your TDEE is 1800, 1200 was the cause of all my past problems as it's simply not sufficient for my body and sets off a starve/binge cycle that's hard to break (I seem to be managing much better on IF than ever before though). So yeah, like others have said, I'd also set MFP to sedentary and maintain, eat up to 10/20% under TDEE 3 days, 2 fasts and maybe a wee splurge at the wknd. That way you can live like that forever and you're off the merry-go-round.

zedzedzed · 10/02/2014 13:07

*LONGterm...not log.

Not2bObvious · 10/02/2014 13:20

Quick check in - FD here and haven't yet broke fast, problem with water in the office so v dry'drated. Weirdly not hungry all morning, strange that, I wouldn't advise it of course!
Flowers to the newly poorly and all others. I'm just exhausted but story of my like!
bcf have started to check out billy blanks as a tae bo choice, it's pretty good! Might get a run tonight before tea, we'll see.

bibliomania · 10/02/2014 15:17

A wave from a lurker (can't keep up with the thread!)

Have been 5:2ing since last year and have a SV in the form of being down by a stone, from 13 and a half stone to 12 and a half. Down from obese to merely overweight....

But it's the NSVs that have surprised me - over the weekend, I was wandering the aisles of Aldi and walked straight past all the desserts, biscuits etc, not because I was trying to be "good", but because they seemed...irrelevant. I was reading the weekend newspapers and flicked past the chocolate recipes to halt at some vegetable recipes. And today at a work meeting, I resisted the cake for the first time ever (okay, that took some effort. But ultimately it was easier to continue the FD than start it again tomorrow).

It feels like I have stopped panicking over food, and I no longer feel the need to grab tasty treats before they're snatched away from me, because I know in fact that they'll still be available tomorrow. The change is as much in my head as in my waistline.

Today's FD involves an avocado at lunch and smoked and salmon this evening. Seems more like a treat than a penance - and my overall food bills are down because there is so much less processed food....

bibliomania · 10/02/2014 15:27

That was smoked salmon and samphire that I was drooling over...

TalkinPeace · 10/02/2014 15:41

biblio
walking past the snacks aisle is a major NSV
well done.
It proves you have retrained your brain to start thinking like a thin person.

And yes, the saving in shopping bills can be really substantial.

I should have been fasting today but ran a training seminar this morning and my brain hurt
so I came home and had two scrambled eggs piled onto a thin slice of corned beef with pepper on top.
Warm corned beef and scrambled egg is LUSH - it all fitted onto a side plate and I'll have a smaller supper tonight.

BigChocFrenzy · 10/02/2014 15:49

Excellent news, Biblio, well done.
The NSVs are even more important for your longterm health than the SV.
