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!

I did my first FD yesterday and don't seem to want so much to eat today as I normally do. Is this to be expected and will it continue as I do more FD's?

MummyPigsFatTummy · 22/05/2013 14:46

I am afraid you may be right, Eagle. That is what is bothering me. I will just have to cross my fingers and hope for the best. I can't go below 500 calories. I will try not to go mad on NFDs.

awomanchanging · 22/05/2013 14:54

spababe it has happened to me as well. I'm on day 5 I did 2 consecutive fasts and since then my hunger seems suppressed. Which I have no problem with. Usually after a morning workout I'm veryyy hungry. But now I'm fine and dont even feel like eating. But i eat anyways to feed my muscles.

awomanchanging · 22/05/2013 14:55

mummy yes slower metabolism means slower process of breaking down fat and losing weight. But you could do everything right to still be efficient as possible.

fastyspeedyfast · 22/05/2013 15:02

mummypigs I'm also hypothyroid, though not on HRT. Honestly, I'd see your GP. I've been doing this for 7 weeks and have lost roughly half a pound/week. To me, this is good going. You know how sensitive those thyroid med adjustments are! So go in for a check on your levels and tell them you're doing 5:2.

MummyPigsFatTummy · 22/05/2013 15:33

Good idea Fasty. I will do that. I ran out of meds a little while ago and stupidly didn't restock in time for yesterday's first fast, which may affect my results. I need a blood test anyway so will see if GP will do a more thorough check. Glad to hear you are succeeding Smile

spababe · 22/05/2013 15:49

thank you to everyone who has repllied to my questions so far

virginposter · 22/05/2013 16:16

MummyPigs I am also getting on a bit (59) and on HRT and have lost 30lbs since this time last year - hooray! So there is no reason on these two counts why you should not lose too Grin

BetsyBell · 22/05/2013 16:23

Mustnotsnackmustnotsnackmustnotsnack [drinks tea]

MummyPigsFatTummy · 22/05/2013 16:30

virginposter - brilliant Smile. All these posts are so encouraging! Second fast day tomorrow so will make sure to take thyroid meds tonight so I don't sabotage myself that way.

Emilythornesbff · 22/05/2013 17:25

Shit!
Probably should be kicked out of the no snackers club for those bastard chocolate hob nobs (bought by dh. I never buy stuff like that [sob])

ELR · 22/05/2013 17:27

Well I've kind of failed at the no snack sort of! Kids had a swimming gala this afternoon and when it finished me and a few other mums went to the pub so I had a glass if Pinot, just to be sociable! And I've had an early tea to stop snacking even though I had a late breakfast and lunch.
Got a really rubbish cold so that may be something to do with it, it wasn't the best dinner either fish fingers, oven chips and corn on the cob! Really couldn't face cooking as feel so rough. Off to take kids to their tennis lesson now so won't be back home till 7.20pm then I will have a cuppa and an early night I think. DH can get his own tea!

Emilythornesbff · 22/05/2013 17:30

Well done virginposter

SkylerWhite · 22/05/2013 17:52

I've been lurking for a while, and have finally summoned up the courage to post...

I've been dabbling with 5:2 for a while, and finally decided to give it a proper go over the next few months. I have a normal BMI (5'4" and 9 stone) but would like to lost about half a stone and generally tone up. So I'm trying to combine it with exercise, doing JM Ripped in 30 every day, and running 3 miles on the non-fast days. Taking 1 day exercise free a week as well.

How long is it before you generally see any results? I haven't seen the scale shift at all - actually that's not true, I've seen it shift in the opposite direction this week - gained 2 lbs, which I am hoping is just sore muscles retaining water!

I fasted Monday, and again today, and am considering making today a zero calorie fast, as I seem to have gotten past the hunger pangs of 3pm. Would that be a good idea to try and kick-start the weight loss?

postmanpatscat · 22/05/2013 18:07

So I walked home from work as usual....

....and when I got home I saw the empty space on my driveway where the car should have been...

...and then I remembered that I drove to work this morning so I had to walk back to work to fetch the car!!!

Maybe today's fast had addled my brain (so much for reducing the risk of senility!)

EagleRiderDirk · 22/05/2013 18:11

Oh no ppc

Prawntoast · 22/05/2013 18:14

dotty re your knee pains and squats, make sure your knees do not go over your toes as you lower into the squat, this is what will put the most strain on your knees.

Good losses everyone, I'm hoping to join you in the 9's by Friday.

BetsyBell · 22/05/2013 18:34

[dons NO SNACKING halo]

Dinner is eaten and I have passed through the snack danger zone unscathed Grin

shakes head and tuts at ELR and Emilytsbff

PPC Apologies but that made me actually LOL, and just think lots of lovely extra exercise and calories burnt!

BetsyBell · 22/05/2013 18:37

Skylar Hmm, sounds like you're putting in plenty of effort - it's not clear how long you've been fasting & exercising though - have you just started this week? Have you been eating to your TDEE on non fast days?

Prawntoast · 22/05/2013 18:40

hi skyler, if you don't feel hungry go for it. I did my first zero cal 36 hour fast last week, wasn't planning on it but came back from a bike ride and just didn't feel hungry. What I like about this WOE is the better reading of when I'm hungry and when I'm not. If I'm not hungry I don't eat.

SkylerWhite · 22/05/2013 18:45

BetsyBell I've been doing it for 2 weeks, although have only added in the JM since the weekend.

Hunger pangs have started again Prawntoast so perhaps I'd better eat something when my DH gets home. Speaking of prawns, I was thinking of making Nigel Slater's prawn noodle soup, which I think should be about 300 calories per portion. Might have to rustle up something supplementary for my poor DH, he'll be wasting away!

Prawntoast · 22/05/2013 18:51

skyler, if your muscles are sore from JM and mine are when I do any of her workouts it may well be your muscles retaining some water. I did a lot of JM workouts last year and found that the scales didn't budge that much but I lost inches, I'd measure yourself as although the scales may not budge much you will still decrease in size!

Dotty342kids · 22/05/2013 18:51

Thanks prawn, no, have been making sure that knees, toes etc are all in the correct places when doing squats Smile. Broke the 180 down into chunks of 20 today and that seemed to ease the knee issue so think that'll be the way forward from now on!

Just had enormous pile of vegetables with my veggie pie for dinner tonight and feel well and truly stuffed now but at least it was only about 600 cals all in and it should help keep my tummy happy for most of tomorrow morning. Although tomorrow's a NFD (as DH wanted to fast Friday instead of Thursday this week) I have got a really busy end of the day and may struggle to get a cooked dinner in. So, plan is to make a nice chilli in the morning and eat it at about 2pm tomorrow. Then can grab a quick sandwich for tea if I need one and then it's Fast Friday....

SkylerWhite · 22/05/2013 18:55

Thanks prawn. Today's workout - day 4 - was the first one I managed to do without pausing the video, so I'm hoping this might mean that I've broken through my body's outrage at so much torture! Did you find the JM workouts worthwhile, in the end?

Prawntoast · 22/05/2013 19:01

skyler, I think JM's workouts are definitely worthwhile, I did lose inches and my overall fitness increased. What I didn't do is combine it with eating less! Now I have this WOE, I use a mixture of her workouts plus cycling to keep fit. I prefer her longer workouts, Banish Fat Boost Metabolism and No More Trouble Zones - especially the latter, my arms scream after that one. If you haven't already found it, there is a JM thread in this topic somewhere, some seriously hardcore JM fans on there.
