The continuing thread for those of us following either the 5:2 diet or the alternate-day fasting diet.

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 what you like, or approximately your TDEE (see explanation below). Alternate-day fasting is just how it sounds; you fast every other 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.

ADF = Alternate-day Fasting, as it says on the tin, fasting every other day rather than 5:2.

NFD = Non fast day

NSV = Non scale victory

Michael Mosley has a website to accompany his book on the subject. Please go check them out, as he's the whole reason most of us are here!

I know a number of people lurk on this thread, as this is currently quite popular. Please just jump in and post if you're new- you'll find a lot of support here.

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 our very own 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.

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!

Hi all checking in and wanting a bit of hand holding really ..Sunday was amazing my surprise hotel looked right over the Thames and Dinner was divine, there was also cocktails, champagne and chocs, next day was full English Blush , tried to fast yesterday but gave in and had choccy biscuit, tapioca crisps and bread and butter on top of my 500 cals. I know why was v tired and nervous. Have to go to local hospital today to have breast lump investigated. Hate that Sunday was perfect makes me think something more likely to be wrong [weirdo emoticon]. I wish today was over...anyway Camp bestival tomorrow, lots of lovely food some of it healthy and not taking any 3 litre bottles of cider with me this time ! Next fast day will have to be Tues ....can someone pm me a gentle reminder kick up the butt lol?

smellylittleorange · 31/07/2013 10:36

Ha ha Tommy and Eaglerider Totm due for me to. This is the first time in ages have been able to lose during the weeks preceding though!

Doitnow · 31/07/2013 11:04

Hello. Can I join too? Today is my second fast day of my second week, might do 3 this week if I can.

I've been a yoyo dieter all my adult life so am looking for something I can stick to in the long term. I've always lost weight with SW, WW etc but got bored and so weight has crept back on. I've generally weighed between 11 and 13 stone but never been particularly happy. So think I need to be well into the 10s to be more confident about my shape.

Thank you all so much for all the tips and encouragement to date.

Talkinpeace · 31/07/2013 11:09

Doitnow Welcome - you have come to the right place, because 5:2 works even when you no longer want to lose weight :-)

BetsyBell · 31/07/2013 11:17

smellylittleorange good luck with your appointment xxx

Have a fab festival :)

Londonmrss · 31/07/2013 11:35

thanks TIP. But I'm fasting 2 or 3 days a week so I'm still doing fasting aren't I? Just with calorie control the test of the time. Are lots of people fasting every day then?

PandaPops76 · 31/07/2013 11:38

Hi everyone - another newbie here de-lurking! I've found your posts and stories really inspirational, and am hoping you can help me stay on the straight and narrow. Today is my second FD of second week: week one went OKish, but FD this Monday felt really hard: I just felt knackered and grumpy all day, and was chewing my arm off by the end. I think that part of the problem was that I had been following MM's pattern of breakfast an supper, but found that the former really woke up my appetite so that I just felt ravenous by about 10.30. So having read advice here about 8:16 and skipping breakfast I am trying it that way today, and feel much better so far......

Normally I would have FDs on MOnday and Thursday, but am doing today instead as I had a fight with a jar of peanut butter last night and the peanut butter won Blush. Snacking and grazing - particularly on seeds, dried fruit and PB are my downfall. Puddings I can take or leave, chocolate: meh but PB is my nemesis. I normally don't have it in the house, but my 3 year old DD loves it so I've relented.

My goal is to lose 7-10lbs: not much, I know, but the stubborn buggers just won't shift. I'm 36, 5 foot 4 and weigh 9 stone. Pre children I always weighed about 8.5 and would dearly love to get back to that, and to maintain it without feeling constantly deprived leading to massive blow-outs, and then guilt-starving myself, which is what I've done all my life. I'm acutely aware of setting a better example for my DD, as I want to be able to enjoy food without guilt and not pass my f*ckups on to her, and I'm really hoping that this WOL will help my whole relationship with food, and food-induced guilt - to shift and the latter to become a thing of the past - well here's hoping!

God I'm going on about myself aren't I - sorry! A couple more things: I'm breastfeeding my 15 week old DS, and also have hypothyroidism (probably caused by years of dieting, I reckon).

Right, enough about me (ashamed face!)

Talkinpeace · 31/07/2013 11:57

Londonmrss
I tend to do 16:8 every day - otherwise known as skipping breakfast and not snacking - as it keeps my stomach small so staying within my (now rather limited) TDEE is easier.
If you are doing a couple of proper fasts per week, then several small meals on other days is probably fine - especially if you are still losing / already a healthy weight.
But, as per the thread title, its part of the whole healthier relationship with food - getting families to sit and eat meals together rather than kids watching Mummy browse ...

Talkinpeace · 31/07/2013 12:01

Pandapops welcome, and we LOVE hearing about why new people have decided to delurk - it helps us to stay more welcoming.
And yes, getting a long term happy healthy relationship with food will help our children too, and their children, and the planet.
Not that I'm evangelical about it, mind.

PB - nom nom. I used to eat loads. I guess the thing will be to set a no snacking rule on it. PB sandwiches for brekkie for her - when you are tidying not eating - and then maybe for lunch, but no snacks for either of you and the jar will last a while.

BetsyBell · 31/07/2013 12:03

londonmrs Ultimately it would make sense to aim to eat 2 to 3 times on most normal days rather than several smaller meals. As a first step perhaps aim to reduce down to 4 smaller meals on week days and work your way down from there?

I realise that doesn't necessarily sound appealing to you at the moment but you may find yourself heading that way naturally if you stick with this WOE so you may as well help that process along.

There are lots of links to some good science regarding eating less often on the tips and links thread (link in OP)

BetsyBell · 31/07/2013 12:06

I'm tentatively pleased to report that I seem to have managed to get the kids to stop snacking. We are all learning great life lessons here :)

HellesBelles396IsDeeplyUncool · 31/07/2013 12:32

Eating to 90% of tdee without fd's because that seemed reasonable while I have an ear infection. 5 more days of treatment so back next week. Enjoying reading how everyone's getting on.

PandaPops76 · 31/07/2013 13:38

TIP I wish it was civilised PB sandwiches - I tell myself that the bread has too many calories so just eat the PB from a spoon to "save calories", but then of course eat another spoon, then another, then another - d'oh! I know it could be worse: when I was pregnant with DD I used to do the same with jars of Nutella and would get through a large jar every two days - but think that I'll really just have to stick to the absolutely no snacking rule because once I start I have no brakes whatsoever - sigh!

Hellesbelles Sorry to hear about the ear infection - they are the worst! I hope you feel better soon x

AFM: so far so good. Managed to keep busy with DD and baby all morning and didn't notice feeling hungry at all - yay! Just finished lunch (egg white omelette with mushrooms and side of raw spinach - yum!), and am gearing up for an afternoon of black coffee. Good luck to all of todays fasters too!

swallowedAfly · 31/07/2013 13:51

amazing pics betsy! well done you.

yes it's the space between 10st and 9st where i genuinely start to get 'slim'. up to that point it's just losing more and more podge but plenty still available. i reckon 9st7 would be pretty good for me and hopefully sustainable. at under 9st i feel really happy with my body but it is not sustainable ime and usually only reached through illness or major stress and hell times iyswim so not really desirable Wink

good to hear every pound makes a difference from here on in and thanks for sharing those pics! inspired me to check my bmi for first time in a while and it is 22.09 so well into healthy zone now. 9st7 would be 20.82 so still healthy and realistically i guess much lower would be pushing it.

somewherebecomingrain · 31/07/2013 14:12

Hello

Best fast day yet on Monday - managed to eat all my cals as one meal at 4pm and used coffee to help me last till then.

Had lots of energy and didn't eat much the next day - beanshoot salad and fish cakes kind of day

Today have lost another pound. Am sitting around and eating cake on the principle of 'keep your metabolism guessing'.

somewherebecomingrain · 31/07/2013 14:17

Ps betsy and eagle. I'm right with you on the tummy pouch/apron! Mine tucks into my knickers, after a polyhydramnios pregnancy which went to about 44weeks size wise!

Nice!

EagleRiderDirk · 31/07/2013 14:22

somewhere I've got a great image of you covered in cake repetitively going 'well you've got to keep the body guessing' Grin

BetsyBell · 31/07/2013 14:56

somewhere I had one of those pregnancies too! I was HUGE. I soaked the consultant when she burst my waters for me!

In a way I'm surprised the damage isn't worse now I'm finally slimmed down.

Saf I put the BMI on there as I wanted to show that it's possible to be lean and healthy without having a tiny weight (and it's not all muscle!) and that we should all try and appraise ourselves without relying on stats and scales. Photos are good for this.

If anyone in real life was guessing, I'm pretty sure they wouldn't put my weight at nearly 10 stone (I'm 5'5").

OP posts:
EagleRiderDirk · 31/07/2013 15:03

somewhere and betsy I didn't have that but I had two very large babies - with DS I was showing about 43 weeks when I had my csec at 39 weeks. I can't, however, totally blame them for the state of my tummy given that it was in a pretty poor state before them! But I may try when they're older Wink

Dotty342kids · 31/07/2013 18:29

NFD here today, been to zumba and swimming with DS (well, he swam around me, I just sort of......... floated!). Had a normal breakfast and lunch and then a repeat of Monday's FD dinner, just because it was seriously tasty! However, have scoffed a couple of slices of home made rocky road during the day too so it's definitely a NFD Smile
Fast day tomorrow and I'm already thinking about what's going to be for tea.
I really need to cut out evening snacking, at the least on the night before a fast day, in order to do maximum hours of fasting so that's it. In the words of ...... someone up thread (probaby TIP), "The Kitchen Is Now Closed"!
Catch up with all you Thursday fasters in the morning Grin

JB30 · 31/07/2013 18:47

Second FD dinner in, lovely small portion of what everyone else was having, had enough left over for lunch on mini FD this Friday. Did a slow jog again this morning, so that's my exercise done. I have about 80 cals left and am contemplating a dessert of a mini bounty as I do still feel hungry but then am I really? Yeah of course I'm hungry! I only ate 420 cals today biting into bounty, wrapper still on

Doitnow · 31/07/2013 21:04

Hello. Survived my fourth fast day. About to go to bed before I raid the kitchen!

Is it odd that I'm quite enjoying being hungry? I've always felt the need to be full, not satisfied with having just enough, hence why I've always been overweight.
Were any of you long time fasters the same? I'm just curious as to whether I can retrain my body to be ok being hungry? I've always rushed to the fridge at the first hungry pang!

Sorry for ramble (tired and hungry!) but I hope you get my gist!

Thanks

BsshBossh · 31/07/2013 21:50

Doitnow 6 months in and yes I do enjoy the empty feeling of hunger. It's why not snacking on NFDs work for me because I like that empty feeling between meals - I like feeling light.

Doitnow · 31/07/2013 22:09

That's a really good way of thinking about it- feeling light.
Will focus on that on my NFDs. I know it sounds really superficial but I really want to be able to buy lots of nice clothes rather than being all frumpy!
