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 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!

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.

There's a link to the aforementioned Horizon 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.

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 diet!

MrsF A sleep-deprived bod screams so loudly for high-calorie comfort food that you are nearly certain to give in (unless you are tip)

Tell yourself today was a necessary NFD - maybe sub-TDEE ? - and go to bed early. Don't force yourself tomorrow into an FD if it doesn't suit, just do the next scheduled FD. This is a WOL that fits to your individual life.

CuckooAtchooUhOh · 11/11/2013 19:06

TwinM - I posted about exactly that the other week! I joked at time but was actually serious. Some days it is so easy you do start to wonder if you've eaten unawares! Dream feeding lol!

Another fd here today when I've not struggled. As predicted I def seem to find it much easier at certain times of cycle. Hormones are saboteurs! Or slap a bit of stress in there and it's suddenly a different, harder ball game. But today, I feast on fresh air and am full. (Plus the thousand or so drinks I've had!)

Still having dinner though. Obviously!! :)

toffeesponge · 11/11/2013 19:11

I will read to catch up in a minute. Wanted to say technically I have failed for a FD (had 2 slices od leedarhammer cheese, a small home made croissant and 1/2 a choc topped doughnut) but considering how far I have come, have had a very sick DD for over a week and have just got back from suddenly and unexpectedly having had to have my Guinea Pig put to sleep I think I am doing okay and surely it is still a mini FD? The doughnuts were for the kids. When we are sad I make a particular cake and no time today before bed for the youngest so I bought the doughnuts.

BigChocFrenzy · 11/11/2013 19:13

Betsy 4500 cal Frenzy is the once weekly norm.

A Frenzy is often a normal meal followed by high-density cals
e.g. A 250 g jar of nut butter looks small, but packs 1625 cals
5 small tubs of ice cream can be 1500 cals
A 200g block of cheddar + 80g nuts + 100 g choc = 1900 cals
8 donuts or 4 choc muffins or pack of bix = lots !

Alternatively, a meal portion Frenzy can be:
2 pizzas + 3 portions fries
Or a 400g Fondue (1600 cals) + bread
Or 3 plates of a healthy meal such as cheesy pasta or roast

Have I made anyone peckish ?

BigChocFrenzy · 11/11/2013 19:15

toffee You did really well to struggle through a respectable FD amid all your problems. Well done !

BigChocFrenzy · 11/11/2013 19:25

FD nearly at an end. A rest day from training, so 100 cals

Betsy I train 5-6 days per week, always high-intensity intervals (so a bang for my buck) whether cardio or weights. Weekly total only 9-11 hours, depending on energy levels / social life.
I also cycle (leisurely) to and from gym and work, but just 4 daily trips, each only 2 miles.

BetsyBell · 11/11/2013 19:28

Too rich for my blood bigchoc, that list has made me feel a bit green. I get full really easily these days!

I haven't had fondue in nearly 10 years Shock

Toffee Deffo mini fast. Considering how much stress you've been through I am very very impressed with your restraint. (((toffee)))

I have failed my fast day. I'm calling it a mini fast. I realised today that I need to curb my coffee habit Sad. Stupid headaches.

Eat Thanks for the lovely Inspirations thread !
Flowers

rubbishfamily333 · 11/11/2013 19:39

I also love the inspiration thread Grin I hope to be posting on there sometime soon Wink

MrsFlorrick · 11/11/2013 19:53

Eat, Talkin, not, bigchocfrenzy and Cookoo. Thanks Thanks

I had sushi will the DC had macdonalds (bluewater food court). So current cal count is 1500 for the day. So well under TDEE. And that's where it's staying!

DC in bed asleep. And the awful constant whining sound has ceased for now. Ugh.

I know they are only small but the noise!

Tiredness doesn't help. Makes me either unable to function or like today I just feel really angry. DH and his lack of help also enraged me.

Brew And then to bed. Tomorrow is another day.

If the night is good then FD tomorrow but if the small ones are up again then forget it.

Hope you've all had a good day and a lovely evening planned.

BsshBossh · 11/11/2013 20:02

Big hugs to MrsF and toffee.
xCupid sounds like you're doing really well!
Coffee well done for lasting the day :)
eat your latest photo is amazing and thanks for starting the inspiration thread (great idea Betsy), I'll add to it soon (need to anonymise my photos first so I can keep them permanently up on my profile).

My FD is coming to an end. Will have a Cox's apple and small mug of soup when DH returns home. He's fasted too all day but as he's not in weightloss mode he'll be eating leftover risotto and fruit tart.

Goodness, 2 NFDs tomorrow. What do I fancy eating :) ?

Talkinpeace · 11/11/2013 20:10

I do remember the grinding exhaustion of small kids.
When you curl up next to them to settle them in bed and wake up four hours later with cramp and always feeling jetlagged.
Mine are older now which makes planning my time much easier.
Even getting a semblance of organised a few days a week is better than nothing - and you can always fast tomorrow

CoffeeOne · 11/11/2013 20:11

I'm at about 530 calories for the day. I feel full although my evenings are a problem, it's where the mindless snacking occurs! I'm getting through it knowing I can eat approx 3 times as much tomorrow!

cuckoo thanks for your lovely offer to be double day buddies but I'm going to have to do my second day later in the week! I'm looking forward to tomorrow's food already :D

BsshBossh · 11/11/2013 20:20

Well done Coffee! As you get more used to fasting you'll likely find you're able to push your 500 cal meal even later (I do, as I'm a night eater too). Alternatively you could save some of your 500 cals for a late night snack

BetsyBell · 11/11/2013 20:30

I'm very impressed with all you fasters with young kids - it took for mine to be at school full time before I could even think for a second about sorting myself out.

I do full well remember who utterly exhausting and difficult almost everything felt some days. So a massive well done to you all. I'm not sure I could have even contemplated doing this back then.

Junebugjr · 11/11/2013 21:02

MrsFlorrick - how old are your dc, mine are 5 and 2, I can sympathize with the constant whining, squabbling, and demanding! I spent 3 hours this afternoon, fending off dd2's burgeoning tantrum, only for it to hit just before bed . On the brightside, I didn't have time to think about food, just shoved something healthy down. DD2 starts school in May when she's 3, yes!!
bsshboosh thank for the reminder for Fat again, got it on!

CuckooAtchooUhOh · 11/11/2013 21:17

Well done all you first day fasters!!!! Whatever you managed - it was a start. And you can have whatever you like tmw :)

Coffee I'm an evening grazer too. That's why I have to save my cals for evening! Just had dinner and now got the munchies after all my 'it's been easy today' bragging Hmm
Am not giving up this close to bed though, so it's drink drink drink for me!

Kinda glad you're not up for tmw as right now I am really looking forward to eating anything I want Grin - though won't be surprised if feeling gone in morning as is often case!

It gets easier (usually, so well done!

BiscuitsAreMyDownfall · 11/11/2013 21:28

Another successful FD for me. Big accomplishment today as Ive spend the best part of my morning either crying or fighting back the tears. Soooo wanted some comfort food, but managed to abstain. Feel worn out now, really emotionally drained. Its not right the first thing I do when I park at work is cry about the facgt Im at work. It kind of led the way for the rest of the day.

On a more positive note I went to my evening course and did 2 practice exams and passed them both (real exam is next week) so its had a good end.

xCupidStuntx · 11/11/2013 21:29

I'm such an evening snacker too, I've just had an egg fried in fry light and beans!
I'm really surprised at how far my cals have gone, I'm hoping I didn't make a huge mistake somewhere but I've been meticulous and checked and checked.
I had my tuna and sweet corn bowl earlier, small amount of stir fry veg and Mayflower curry sauce and my egg and beans!! Seems a decent amount.

Ashamed to say....the arse of my size 20 leggings burst today Blush, luckily I was at home but my God how have I let things get this bad!!?
I've never felt so sure that this time really is different!!

You're all such a lovely friendly bunch, I'm so so glad I came over here!!!

CuckooAtchooUhOh · 11/11/2013 21:30

With regards to the gorgeous new Inspirational thread, I feel that a lot of fasters me might like to direct the odd question at particular losers based on the info posted. If this was the case, where would be best place to ask? Here? The Inspirational thread? - though was worried about it clogging up.

I'm just wondering how we would get the attention of a particular person if they're not on here regularly enough to spot a question.

Or should we have once weekly/fortnightly/monthly question and answer sessions!?!?!?!? Grin Grin

duckyfuzz · 11/11/2013 21:33

biscuits that sounds like a crappy day! I'm so impressed you got through it successfully, it's the sort of day that would send me to comfort eating.

I've decided to go to bed to get away from temptation, I'm on about 520 cals and evening munchies are my downfall so bed with ipad and a glass of water it is!

Congrats to all, no matter how big/small the steps are, they're still in the righ direction!

WilsonFrickett · 11/11/2013 21:36

Man my tea was ace! (chicken puttanesca for all of 250 cals). Just going to have a cup of green tea then close the kitchen. Night all, good luck with FD tomorrow...

Southeastdweller · 11/11/2013 21:38

Hi all. Over a third of the way through this thread since Thursday - I guess there's a major feeling of wanting to look tip-top for the festive season Smile

Thanks to eat for starting such a positive thread. This maintainer will post on there sometime this week.

Well done everyone for today. Going over 500cals a little on some days makes no odds with this WOL. You can still lose weight and maintain.

Fasting tomorrow which is a good job as I've been drinking Bailey's like nobody's business the past two nights.

CuckooAtchooUhOh · 11/11/2013 21:41

Cupid you have come to right place. Get ready to sling all size 20 clothing :)

((((((((((Biscuits)))))))))) you poor, poor sod! You sound seriously blue my dear. Are you ok? Is this hormone related or are you feeling like this all the time?
Is it just work? If so, how long until you can ditch it? Focus on your training and for goodness sake get yourself to the docs if this is more than the occasional happening. (Good luck in your exams btw)
Sorry for all questions, just not sure what to do across cyberspace! :(

Sending you lots of Thanks and Cake
