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!

Dottiest Set at 'least active' level you've got 1800 calories to play with - so if you add in the extra for BF you've got loads for your NFDs AND a big deficit on your fast days even if you go up to 1000 calories (which you absolutely should)

:)

BetsyBell · 07/01/2014 21:52

MFP seems to give EVERYONE 1200 calories when set to weight loss Hmm

WhenSheWasBadSheWasExhausted · 07/01/2014 21:53

doris yes we are simlar. Same weight this morning, biggest difference is your extra 2" we can keep an eye on each others progress.

You sound more hardcore than me - starting on 750 so you can spur me on if I start to waver.

OBehaveMaeve · 07/01/2014 21:55

Thank you!

Going to calculate my TDEE for the normal days.
My weight is 133 lbs at the moment. I knew id put on a few pounds over christmas, but i stepped on the scalesand realised the "few" pounds was nine.

DottiestDoris · 07/01/2014 21:58

Thank you Betsy! I best go and eat something. ..

BetsyBell · 07/01/2014 22:00

Maeve 133lbs sounds quite tiny! Those Christmas pounds will slink off in no time :)

DottiestDoris · 07/01/2014 22:04

At the risk of making myself sound even denser than I already do...I now have no idea how to use MFP. Surely it's pointless if it doesn't work alongside the 5.2? Or is ut useful simply as a calorie counter?Confused

TalkinPeace · 07/01/2014 22:08

Dottiest
MFP is great as a tracker.
Set it to maintain but ignore what it tells you about each day.
What you will find is that over a whole week you'll have a deficit of around 3500 calories = just over a pound
once you've done a couple of weeks the reports are great for showing the balance of your nutrients
its also v v useful to quantify the splurges (the number of calories in Roule is fine except at the quantities I ate!)

muffins · 07/01/2014 22:23

Just signed up to MFP and it's only giving me 1240 and I put sedentary and maintain.....is it because I'm a short arse?! (5ft 2)

TimeToPassGo · 07/01/2014 22:25

Hey folks, new non-festive name for the new year. Still reading along as much as I can but I'm doing WW for a bit. Plan is to combine it with 5:2. I was just going too crazy on my NFDs and need to relearn sensible portions. Hoping to lose between 14 and 21lbs on the combo approach, then use 5:2 to maintain. That's the plan anyway :)

TalkinPeace · 07/01/2014 22:25

muffins · 07/01/2014 22:26

Oh no it's ok I was being a plum, it's 1740, still expected it to be nearer 2000 but guess that's prob where I've being going wrong all this time!
Good luck to all of tomorrow's FD'ers

muffins · 07/01/2014 22:27

Tip that one gave me 1674....think ill stick with the 1740 Grin

WhenSheWasBadSheWasExhausted · 07/01/2014 22:38

Thanks talkin my TDEE is 2011 but does not take into account bf. at the moment I'm not monitoring my intake on a nfd. Might start in a few weeks.

CuckooAtchooUhOh · 07/01/2014 23:30

My first successful fast day of 2014 completed!!! Woohoooooo!!!!!!!

I'll be honest - thought I was going to fail.

In fact I was 5 mins away from failure. Had decided I needed a nfd type meal tonight as been feeling rubbish (bug ish) today.

I made a garlic, bacon, mush, onion, baby toms and chilli flakes concoction to stir soft cheese through before adding to pasta for him and myself. But had a last min swerve!

Instead I split the mix, added only tsp soft cheese to mine. Instead of pasta I chucked it through some shredded red cabbage and carrot ribbons and added a splash of balsamic. Let it wilt a bit.

Was absolutely delicious. Better than the pasta would've been in fact. Best of all it has left me on target for today minus the 2 chocs that followed well under 600 anyway. I'll take that!!

I am going to feel so happy in the morning and am glad to have taken first step towards normality again. Result!

Papayasoup · 08/01/2014 00:11

Well done to all the newbies taking the plunge and finding your way.
When I started working out my TDEE was a revelation as I'd always thought like someone else it would be closer to 2000 but was 1700 which explained why without counting but loosely monitoring weight had crept up over the years.
I also didn't set myself a weightloss target as I'd failed all of the previous year on that. Rather I picked a pair of jeans I liked but could no longer fit into. Although I do weigh myself my real goal was to get back into those comfortably. Which I did! So I'd really recommend, especially for those who get disheartened by scales to pick an item of clothing and every 3-4 weeks try them on.

BigChocFrenzy · 08/01/2014 00:16

Well done, cuckoo on breaking your 2014 duck. Oooh, that sounds too avian. Now you are back in the swim. Are you 5:2ing or 4:3ing ?

We cope differently on FDs. Your food always sounds so tasty it's dangerous !

I can't cook yummy things on FDs (or indeed at all - ceiling scrapings anyone ?!) because it might wake my sleeping appetite. So, I usually have a 100g pkt of smoked salmon and just add pickled onions , cherry tomatoes & lemon juice - no cooking !
Alternatively, I have a low carb ready meal or protein shakes, because they are fixed amounts.

BigChocFrenzy · 08/01/2014 00:19

Oops, how did that happen ?

hopefulgum · 08/01/2014 00:29

Talkinpeace, I used that TDEE calculator (on the fast diet website) and at my goal weight (65kg to start) with moderate exercise it gives me 1724, but on another calculator (I think the one that is in the OP for this thread) I was given 1880. That seems a huge difference (both times I put in ideal weight rather than weight I am at now). I wonder why there is a difference?

Anyway, I've been trying to stick to 1700 on three non fast days so I can go over a bit on the weekends.I have my fingers crossed that when I get to Friday morning's weigh in there will be a loss! Surely if the science is anything to go by, I will see a loss. I had some chocolate yesterday, and some beautiful new potatoes from the garden, all garlicy and delicious, but still stuck to TDEE. I really like this WOE.

Dottiest, MFP must give everyone the same TDEE for weight loss. Mine was 1200 calories too. Honestly that would drive me bonkers and set me up to fail. It would be altogether too much deprivation. I have a friend who did stick with it and did lose 10 kilos, but has found it a challenge to maintain and is still using MPF a year later to keep on top of it.

I am hoping that I wont have to use MFP forever, once I get used to what 500 cals looks like and likewise on my TDEE. It is a great handy tool now though.

Cuckoo, your ribbon vegie pasta sounds divine.How much bacon would you say was in it?

Really loving this thread! It is so good to get up everyday and read the day's chat. It really makes a difference to feel armed with knowledge, to get so much advice from the pros (long term 5:2ers) and to commiserate with others. Brilliant!Thanks Thanks Thanks

Papayasoup · 08/01/2014 00:38

[hopeful] I've been the same with MFP. Used it religiously the first few months to get a better sense of what 500 and 1700 looked like, and what my weekend eating looked like! But I've found I don't need it now but occasionally use it to check in. I'm sure you'll find the same too.

Are you on a FD today?

I'm thinking I'll try and do LOF until a normal dinner, which is already planned to be chorizo pasta. So possibly more of a mini-fast. But I won't sweat it if I feel like I need something at lunch.

hopefulgum · 08/01/2014 00:45

NFD here. I like to fast on Monday and Thursday, so I will fast tomorrow.
