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.

Michael Mosley has a website to accompany his new 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:

First things first, here are links to some of our previous threads: most recent one before that another one!

Another thread which breadandwine has started is a good resource for some of the links and tips 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, btw. 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. Sorry if I haven't given credit where it's due, but it was just enough of a job getting all the links re-copied and back into one post.

Come join us, and tell us about your experiences with this diet!

Well done non snackers - this is something I need to work on as well!

This is Fast Day 3. I felt a bit queasy this morning but ultimately it has been fine. My M&S 300 calorie prawn and giant cous cous thing is in the oven - couldn't be arsed to cook tea tonight. Am starving now that I can smell it cooking.

Still no idea what I weigh but I have lost almost an inch off my waist which I think means things must be going in a good direction!

Emilythornesbff · 21/05/2013 19:24

Hi.
nofork I hope you're feeling better.

So, fellow former snackers, how's it going?
I'm on a NFD today and as usual I haven't counted calories or avoided treats, but I have stopped snacking.
I had a large breakfast; toast, egg, apple, yogurt.
No lunch.
Dinner was lasagne, garlic bread Blush, salad [polishes halo], and [whispers behind hand] 2 mini magnums Blush Blush.

It wasn't difficult to skip lunch and avoid snacks but it did take some effort and concentration. I was out with dh at lunchtime and we could easily have had coffee and cake, but I had a cup of tea [smug].

So I reckon, although it's been a greedy day meals -wise, I know that I would easily have eaten more and I was aware of urges and opportunities to snack but didn't cave.

I like the idea of skipping a meal on NFDs
Lunch can e a PITA anyway.
Now I just need to keep up the no snacking rule and Stick to one mini magnum absolute max Grin

Oh, and get that Pilates DVD out and do that.
Sorted

FairyArmadillo · 21/05/2013 19:26

Marking my place before I read through. My 4th fast day yesterday. It's a lot easier now. My friend told me I looked slimmer today, though I haven't weighed myself. Just noticed my clothes are slightly looser and I'm eating less between meals on feast days because I'm not hungry. After a fast day I feel quite cleansed.

The biggest bonus, the best unexpected side effect- my PMT. I struggled so much with PMT. Posted on here about it. Bought supplements, cut down on coffee, went on long walks for exercise etc etc. I track my cycle with period app on my phone so I can brace myself for the evil moods. I've been bracing myself since the weekend and I've been fine! I'm so happy about this. Cannot adequately put into words how happy I am about this!

frenchfancy · 21/05/2013 19:27

For you none snackers who are going to struggle to meet calories why not do what I do (and some other maintainers) and bank them for the weekend. I am often 2-300cals under Tdee during the week (whenI don't drink) but I am often over at the weekend when the wine (and peanuts) come out. Over the 5 NFDs it averages out at about TDEE.

ELR · 21/05/2013 19:30

Hi french don't worry that is exactly what I am going to do!
It's def good advice as I always tend to over indulge on a weekend especially as I usually bake Friday and then do some form of bread at the weekend too.

INeedThatForkOff · 21/05/2013 19:30

Well, three fasts in and I seem to have got to the fabled point I didn't really believe in, at which I stop wanting to eat so much on NFDs. I wasn't intending to join the non-snackers because it's my birthday tomorrow and I'll be snacking then for sure, but today I have managed it quite by accident.

If it doesn't sound to patronising coming from a relative newbie, I have a tip: I had a big breakfast today of beans on toast with cheese on top. I don't know why; the mood just took me and I'd already planned it for lunch. I had that at about 8:45, and really, I've not felt especially hungry all day. That's not to say i haven't eaten meals since - I have, but no picking.I'm going to try it again on Thursday.

So my tip is try a bigger breakfast than usual.

Another thing I've noticed as a BFer is that fasting hasn't caused any problems with my milk supply. In fact, twice this week I've expressed 10 oz in one sitting; once on the second day after a fast, and today, directly after a fast. I usually only manage 5oz. This baffles me, I have to say. Anyway, if there are any lurkers unsure whether to give it a go whilst breastfeeding, it hasn't caused me any problems. That said, I did wait until DS was 6mo and starting to have solids.

meandmyfour · 21/05/2013 19:35

Hi dines I'm fasting tomorrow. So much for my no snacking plan. All fine til 4pm, biscuits and chocolate.

Oh well, good fast tomorrow hopefully

Emilythornesbff · 21/05/2013 19:38

ineedthatforkoff I did the same thing with breakfast today. It was good. I will be doing it again. Lunch can be a bit time consuming anyway.

frenchfancy I would consider "banking" snacks but reckon I ate quite enough today with just my meals Grin Blush

BsshBossh · 21/05/2013 19:40

betsy, ELR, other no snackers. Successful no snacking NFD (NS/NFD?) for me today. Skipped breakfast as usual then had a hearty lunch around 2pm that is still keeping me full and am in no danger of snacking until dinner at 8.30pm. Dinner will end with dessert Smile. I was reading The No S book and he said that to begin with you'll load up your plate more than usual at mealtimes but eventually you'll learn how much food keeps you full for 5 or so hours and you may even find you serve yourself less. I found that reassuring!

headintheclouds · 21/05/2013 19:45

welcome crystal and daisy ,and all other new posters. crystal I lost 2.5 lbs in week 1 and then went up 0.5 lb in week 2! My weight loss has been slow since .Ive never lost more than 3/4 lb in a week ( have been doing this since Jan and lost 10 lbs. Every now and again I post about my slow loss to have a whinge about it on here, but I have no intention of giving up and that has alot to do with how supportive everybody is on this thread.Some of the amazing losses from people like Bshhh , postman combined with the encouraging posts from virgin ,TIP et al ...really do keep me motivated .I read the thread religiously on a daily basis desperate to know how everyones doing.dotty and saf are my thread twinsSmile
Have been on a fast day today and have just had a lovely dinner of chicken breast stuffed with mustard and cheese ,wrapped in Parma Ham .Baked in oven with vine tomatoes and a side of steamed broccoli and mange tout.( devine and just under 350 cals). Everything tastes better on a fast dayGrin

BsshBossh · 21/05/2013 19:52

postmanpatscat, Moominlandmidwinter I'm with Frenchfancy - I don't log calories anymore so actually don't really know if have undereaten my TDEE today through no snacking. But I do know that it'll somehow balance itself out eg at weekends (where I won't be so strict on my no snacking rule) and special days eg holidays, birthdays... So I'm not yet too concerned about it. postman you've reached goal weight too haven't you. Like you, I think, I'm still losing but I'm trusting still that over time it will balance out. For now I'm just making sure everything I eat is full fat.

postmanpatscat · 21/05/2013 20:03

I would save my calories for Wine but I'm a non-drinker so I have to save them for chocolate instead!

Came home and started an ironing marathon so haven't had dinner yet, let alone 1000 cals worth!

headintheclouds it's lovely to think I'm inspiring someone :)

BetsyBell · 21/05/2013 20:03

Bssh re NO SNACKING I didn't upscale breakfast or lunch so I was pretty fiendishly hungry by dinner - a delicious pile of pasta, salad, prawns, veg, avocado & feta. I did then sort of panic and ate a vast quantity of chocolate covered raisins and peanuts (as dessert?) so now feeling a little overstuffed.

But I have now made it my mission to not buy those tempting things (I don't normally have them in, not sure what I was thinking Grin).

Luckily I'm not an evening snacker so that's my first NFD non-snack day done. So even though I still ate the naughty things, I ate them as part of a meal rather than letting loose at my habitual time.

Now the chocolate is gone, tomorrow I can raid the fruit bowl or have yogurt for pudding as I normally would on a weekday.

Where's akarucker? Haven't heard from her for a while... or am I just missing posts in this speedy thread?

Hello Cockbollocks (love it!) It gets easier I promise Smile. You can eat quite a sizeable amount for 500 calories if you pile up the veg alongside your protein, certainly helps me get through a fast day.

Itsaboatjack · 21/05/2013 20:27

Come on cooker, cook faster! My dinner is in the oven and I am hanging out for it Grin

Dotty342kids · 21/05/2013 20:33

Betsy I'm sure I've seen akarucker around in the last few days......

I agree with headintheclouds, it's the support, stories and enthusiasm from everyone that keeps me going on days when I might otherwise lose steam!
Today I've religiously tracked on MFP now that I've discovered I've got 200 less cals to play with on my NFDs Shock and realised that I had definitely reverted to overeating on them.
I've already inputted my planned meals for tomorrow and am pleased to see that they allow for a little bit of Cadbury related indulgence which I shall enjoy whilst working tomorrow evening Smile.
headintheclouds that chicken thing sounds lovely - was it wholegrain / french / english mustard and was it mixed with grated cheese / soft cheese?

Dotty342kids · 21/05/2013 20:33

haha itsaboatjack, what's for dinner?

MizK · 21/05/2013 20:36

Hi all, another newbie here! Been reading your threads for inspiration since starting last week, thanks for keeping me going!

Lost 2 pounds in the first week despite eating way too much on NFDs...

Am currently 10.10 and 5 7 tall - not officially overweight but am a definite apple shape so have a very wobbly out of proportion tummy which I'd like to lose.

On my third fast day, finding it tough because all I can think of is food :(

Am a massive overeater usually, stay just within healthy BMI because I never stay still and have good genes - however I would love to build a healthy relationship with food as well as reaching my ideal weight of 9st 13.

Has anybody really changed how they eat long term on this plan? I realise that you've all probably gone over this lots, but any words of comfort would help me as I pine over my empty tummy!

Talkinpeace · 21/05/2013 20:36

Well it has to be said I'm really impressed with everybody
NO MORE SNACKING is catching on!

And I definitely do not count tea with no sugar and semi skim milk as a snack : if I do not get my caffeine on fast days I'm nadgered. Ditto on normal days.

Feeling dizzy / faint on fast days
drink more : have a pint of water or a cup of tea.
You need to stay hydrated, especially in the early months when you are retraining your system about the fact that reserves come from the muffin top not the stomach.

And remember that from an early supper till lunch the next day with no food at all is 16 hours - only one meal skipped - and will do your system a world of good.

Agree about having your sweet treat (if you really need one) directly after your meal - before you even clear the table - as then your ghrelin "full" switch will stay on so you'll only have a small treat.

BsshBossh · 21/05/2013 20:40

You see TIP, if you keep on banging on about it, the message seeps through to action, eventually Grin. Keep on with the no snacking exhortation!

agteacht · 21/05/2013 20:43

Hi all
Have now done 2 fast days and was 3/4 of a pound down this morning,
A bit disappointed with that but I did overindulge all over the weekend so I guess it could be worse.

Tomorrow is fast 3 and then won't be fasting again till next Tuesday due to being away for the long weekend. Hope that works.

I find the fast quite hard but I have noticed I'm not as hungry as usual on a NFD.
I'm now 10st2 and desperate to get to 9st something. Can never quite get there - constant plateau!!

Itsaboatjack · 21/05/2013 20:49

Stuffed now, dotty it was a huge pile of roasted veg with chilli prawns mmm.

Dotty342kids · 21/05/2013 20:54

If I liked prawns I'm sure that'd be lovely itsaboat! Really wish I did like prawns as I know they're such a fab source of low cal protein

EagleRiderDirk · 21/05/2013 20:55

Today has been quite a hard fast for me today thanks to a mirena induced mini af and pmt from hell. Only a good 4-6 months of this madness...

Enjoyed by broth and crackers though. Very much.

Oh and whoever mentioned Bovril back on the last thread. Flowers Thank you thank you. Its been a complete lifesaver today
