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!

cupcake the 3500 to lose 1lb of fat is a bit misleading. It seems to be an overall figure, like women needing 2000cals a day. Some people will need to cut more, others less. Also, when you lose weight you don't lose just fat, you lose muscle and water too. Hope that helps

akarucker · 25/05/2013 15:19

I just can't do it! I cannot do 'no snacking'. It's too hard...Failed miserably...JUST TOO HARD!

spababe · 25/05/2013 16:30

akarucker could you try something easier eg no snacking before 6pm or no snacking in the mornings then work your way up to no snacking all day??

BetsyBell · 25/05/2013 16:49

Soooo, turns out I do want to stuff my face at this time on non school days too, even though I had lunch 2 hours later than on a school day Confused.

Not snacking but am making dinner early!

aka are you still on adf?

akarucker · 25/05/2013 16:58

bvb sort of on ADF, but actually the last two weeks it's ended up as 4:3 because things got in the way. I'm consequently 3lbs up and losing heart a little bit tbh. It seems that if I deviate from ADF then I gain weight, and I KNOW the answer is reign myself in on NFD, but then I feel deprived like I'm on a diet. And I'm DONE with diets, ehich is why this was working out so nicely. It's going to be hard during half term, too. I may just take the week off and start again after the break. You know how sometimes you're not feeling it? Well, I'm not feeling it!!

Cupcakexprincessx · 25/05/2013 17:19

Thanks for everyones help!

I am not planning to calorie count on my feast days, as I do not want to resent the new way of eating!

I do have one calorie question tho! Once a week me and my boyfriend get a chinese takeaway. We get a small chicken curry, small egg fried rice and one bag of their chips! ( I know not very authentic) anyway what calorie mark would you put this at just for curiosity?

So we order one tin of the curry one tin of the rice and then the bag of chips, this is a small portion though halved cus we share the small between us.

Thanks :)

Keep going everyone! Such great losses!

:)

BetsyBell · 25/05/2013 18:19

aka I know exactly what you mean. For me, on a sunny Saturday evening, I'm stuck at home, I've had some Wine and now I've popped and I just can't stop Wink Grin! I do want to retrain myself out of the afternoon hunger but it's a work in progress and I need the bank holiday weekend off I think. I've definitely felt like I'm on a diet this week... I'll see how I manage over the half term but I'm happy to duck out if necessary and pick it back up in term time.

Emilythornesbff · 25/05/2013 18:58

aka I hear you.
I failed today with no snacking.
I think it's hardest on a NFD when I have no lunch planned.
I've not been too bad but no halos here today Grin

MelanieCheeks · 25/05/2013 19:01

Ran a new personal best time in this morning's Park Run - and it was FUN!

As I was running, I was thinking. The more I run, the lighter I become. And the lighter I get, the faster I run. So since I've lost a stone since Christmas, it's clearly easier to move those pounds around!

Emilythornesbff · 25/05/2013 21:35

Yay melanie

KaleyX · 25/05/2013 22:08

Hey guys,

Do you think that if I stick with this w.o.e and have 2 fast days per week consistently and moderate tdee eating for the rest of the week, I would be able to lose 2 stone by October 2013?

Thanks a bunch
Smile

EagleRiderDirk · 25/05/2013 22:51

Kaley it could be possible. There's about 20 weeks till then and average is about 1lb loss so that's not too far off. Though I know that whilst my weight is still dropping at the same rate that my overall size seems to have leaped since I started the 30 day squat challenge. Its all the exercise I can really get away with at mo. But what I'm trying to say is there's more to life than the scales, so even if you don't drop 2 stone by october you may have lost decent waist size, etc.

EagleRiderDirk · 25/05/2013 22:52

swallowedAfly · 26/05/2013 08:22

morning all Smile

struggling to keep up at the minute but wanted to say hi. i'm sat at 10st10 this morning so only just over my lowest. not sure what i'll manage over half term fast wise so will just try and not over eat and keep the cals low on days where i can. if i fit a fast in great if not not the end of the world.

postmanpatscat · 26/05/2013 08:51

Yay, saf! 10 7 before you know it :)

ELR · 26/05/2013 08:57

aka I hear you on the it's too hard not to snack. It just feels like its a restrictive eating plan and then I end up having blow outs. Didn't snack all week but then went mad fri and sat eve eating crisps and peanuts like they were going out of fashion! Don't even really like crisps and not bothered about salted cashew nuts either! But the way I was stuffing them in you'd have thought they were my fave thing in the whole world.
It's because I was at other people's house if at home I wouldn't have done it I suppose. Up this morning to 10st3.75 which is 3lbs up on my lowest weight.
So what I am going to do is this: enjoy my holiday in Croatia and try not to over eat and when I come back it will be back to good old fashioned 5:2 and tdee on my other days with snacking if I feel like it.
Sugar, snacking, wine if I want it I will have it but only within my tdee. I was losing weight just fine and then I start messing about with no this no that and bam it's blow outs and weight gain!

That's it finished my rant, enjoy the half term everyone!

ELR · 26/05/2013 08:59

Well done saf seems like you are on a roll with he weight loss!

Bramblesinafield · 26/05/2013 09:15

Well done saf, liking your work!

akarucker · 26/05/2013 09:16

ELR I think I'm with you on all of that. It's almost like i had this 'fear' of not being able to snack, so to solve tgat problem, I simply extended my mealtimes to five hours of eating!! Hmm

I'm formulating a plan in my head at the moment. I think I am getting sick of ADF, but haven't been able to move to 5:2 due to complete and utter lack of control on NFD. Right, well, that's going to change. 14 weeks of ADF resulted in 14lb loss. It's time to switch to 5:2. I vow to track TDEE on MFP, and learn what 2000 calories is in 'food' and not chocolate. There really is no reason why I should feel deprived on 2000 cals, and it's worrying that I do. But here's the thing...I can whine about it and stay the same weight, or I can fix it and lose weight. I must choose.

OK, so my grand plan is only at conception stage. I'm kindly going to allow myself half term to psych myself up for it. For those of you that have seen my posts for a while, you will know that it's the NFD that scare me, not the FD, which is why ADF suited me. But, I suspect that ADF is encouraging me to keep the binge mentality on NFD, knowing that every other day 'I'll make up for it'. And that's not good either.

I'm always telling people to mix things up a bit if they get in a rut. Now it's time to act on my own advice.

Well, there's my Sunday morning epiphany taken care of. I'm not going to preview this before posting, because it's probably filled with a load of bollocks and I'll delete it. Best to just click 'post'....

swallowedAfly · 26/05/2013 09:30

tbh aka 1000 cals is enough to get a shed load of healthy veg, lean proteins, complex carbs etc in and you'd still have a 1000 left for eating 'shite'. i don't think all or nothing thinking helps some of us. maybe out of that 2000 you could say right i'm having 1500 in meals and knowing 500 is left over so if needs must i eat it in chocolate or on days where i manage not to do that i've got an extra calorie deficit.

so you say 500 cals a day for shite and then work, gradually, on cutting that down or on only using it every other day or whatever works for you.

i don't add in anymore rules as i'm rubbish at rules.

Dotty342kids · 26/05/2013 09:53

Morning all. After four days of very carefull eating to my new TDEE / fasting I had a lovely relaxed day "off" yesterday where I didn't think about it at all and had lots of nice crisps and chocolate, safe in the knowledge that am fasting again today. Last fast for ten days as off on hols on Tuesday so am hoping as I seem to have got down to 10st 9lbs that I have a few pounds leeway in order to get back from holiday and still be safely under the dreaded 11s Grin

swallowedAfly · 26/05/2013 09:58

well done dotty Smile we really are weight loss twins.

Itsaboatjack · 26/05/2013 10:04

aka I think that's good advice from saf there. A few weeks back I was struggling a bit, similar to you, doing fine on FDs but NFDs were out of control, so that's where I focused and put my energy, I worked out good healthy filling meals then worked out what 'extras' I wanted I what I could happily do without.

dotty good luck fasting today, I'm very jealous of your holiday, I've got another 2 months to wait for mine.

southeastdweller that's a good idea about rewarding my 2 stone loss, I'd not thought of that. I will do, hopefully in a few weeks when it's stuck, I've already bounced up this morning, though not unexpectedly after yesterday's indulgences, not helped by a friend bringing a whole tray of wonderful homemade cakes to the picnic, as well as the wine and all the other lovely bits.

Breadandwine · 26/05/2013 10:05

What works for me is telling myself that "I'm in the zone" at certain times - such as a fast day. I've just stopped my evening snacking by being 'in the zone' as soon as I've eaten dinner (which most evenings includes a pud).

NES, I've called it - No Evening Snacking.

But please don't beat yourselves up guys, for giving way and eating 'too much'. You're just doing what nature intended, by filling up in preparation for the bad times. There's a link to a blog on the Tips thread that goes into this in detail. "We lay down fat in preparation for the winter - but in this society winter never comes," is one quote from it.

Have a lovely bank holiday whatever, everyone! Grin

Cheers, B&W

BetsyBell · 26/05/2013 10:08

aka, elr, reading your posts it suddenly occurred to me that I've healthily lost over three stone without ditching all the snacks! I have felt hungry (and grumpy) all week just for the sake of not eating an apple and a few nuts at 4pm and I've been upscaling all my meals beyond the missing calories and in a less nutritious way.

I will still continue to not generally eat in the evening after my main meal, I also like not snacking before lunch but I will allow myself something after school if I feel like it and therefore continue to have my nice small lunches I've become accustomed to.
