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!

3 days later and I'm back in the swing and have regained control of the eating and Wine . can't 100% say I'm looking forward to tomorrows fast but I'm going to give it the best shot I can. I am looking forward to hitting the elliptical trainer and bike again though, just have to hope ds doesn't want to fight napping!

hope you've all had great weekends and will see you fellow Monday fasters on the other side Wink

Hello all, been lurking for a while and about to start my 4th week - I just had a question though if someone has 2 mins to answer...

On NFDs are you meant to make sure you roughly hit your TDEE, or make sure you stay under it as much as possible? I seem to see different views on this.

I haven't lost a huge amount of weight yet so I was wondering if this might be something I should check!

Many thanks in advance.

theWookiesWife · 28/07/2013 19:41

Hi - newbie here !! 5'8" 165lbs and want to be 147lbs !! Think this 5:2 could be just the kick start I need ! Have also been on MFP for a while ... But stuck in a rut ! So pleased I was told about this site !!!

Some brilliant tips on here !! Thank you all !!!

BsshBossh · 28/07/2013 19:42

Welcome berri. Quite a few of us here take a weekly view - eat under TDEE on week days (though not by too much - you need to have a good difference between FD and NFD cals to trick the body) and over on weekends. But if that doesn't suit you then just eat as close to TDEE as possible on all NFDs.

BsshBossh · 28/07/2013 19:43

Hi Wookie, you're in good company here :)

HellesBelles396IsDeeplyUncool · 28/07/2013 19:48

Been trying a few different tdee-calculators and, though most say 2013, one which requires me to enter body fat percentage says 1797.

What's that about? Does anyone know whether I should cut my daily calorie target to that?

theWookiesWife · 28/07/2013 19:48

Hi BsshBossh ! I'm Feeling positive - so that's a good start ! Will keep checking in for tips and inspiration !! 😄

JB30 · 28/07/2013 20:01

Aborted FD here. Knew this morning when I woke it wasn't going to happen. Adf was possibly a stretch too far for this week. No matter, as is the beauty of this WOL, tomorrow is another day and will be an FD as usual. Have had some terrible cravings for certain foods since I'd been away, I can safely say I have managed to hit them all in the last 5 days, quite proud really Grin Indian, Chinese, Thai, Italian and ehhh chip shop?
Aiming for a 4:3 next week which naturally gives me 3 x 16:8 but will aim to do another 2 x 16:8's in addition. And of course, no snacking Wink
Here's to another week, can't believe it's getting into August and I'm going into my 3rd month of this, havent stuck to anything this long in years. Such a pity I gave myself a setback with hols, but that's life

thaliablogs · 28/07/2013 20:22

tip thanks for taking so much interest in me! I have not been drinking tonnes today although did drink a litre of water at the gym, honestly I know that without that I get really unwell. Between getting home from gym at 11 and 5pm I just had 1 large glass of water and one big cup of green tea, as well as my salad for lunch, yet I felt like shit all afternoon, on verge of throwing up a few times. I don't think I was dehydrated as pee normal etc., and so was just going on some earlier advice re exercise on a fast day (with no bread, butter, cheese etc except the feta I mentioned) that salts might get unbalanced. I do not eat any processed food as a rule, and esp not on a fast day!

I don't usually have this headachy problem on an nfd. And I don't worry about salt balance when I am eating normally.

If that's not the answer not quite sure what to do. I am feeling better now and have had dinner (felt better before dinner) w one large glass of water. Honestly I am listening to you, it's just I need to figure out what is going on with me as I am experiencing thins that I have not previously dealt with. I am also a scientist so it is in my nature to seek to understand!

Will keep going, glad to have another FD under my belt

Talkinpeace · 28/07/2013 20:39

Glad to know you are analytical too.
5:2 works really well for lots of people
Understanding why it does not work for some people will give the greater insights as to why it does.

Some day we will work out why mintyy fails to lose weight while doing everything right month after month ....

Your headaches and hydration are another interesting conundrum that will be useful to review for those just learning to listen to their bodies

as that is the really "big picture" in all this

Dotty342kids · 28/07/2013 21:00

ooh hitc that's brilliant, well done! And saf [embarrassed]

Dotty342kids · 28/07/2013 21:00

or Blush even!!

Talkinpeace · 28/07/2013 21:22

Helles
Use the TDEE calculator on the OP : its the one we've settled on as being the most realistic.
Body fat measures - unless done by a proper full body scan are a bit 'finger in the air'
And yes, eat up to your TDEE on average during the 5 days : so a bit low on a couple of days allows more relaxed and Wine weekends
its very useful to make a not of what your TDEE will be at your target weight to know how little you'll need to eat then .....

HellesBelles396IsDeeplyUncool · 28/07/2013 21:58

Thanks TIP it just seems like so many calories!

Having said that, the reason I'm not losing much may well be that I habe gone over my tdee 9 times in 3 weeks. NFD's - weirdly - are more difficult than fd's.

Talkinpeace · 28/07/2013 22:06

try for always 10% below and then if you slip then you have leeway
also, overestimate the calories in your food
and underestimate the calories you burn through exercise

wrigglebum · 28/07/2013 22:07

Very indulgent last few days as we had family to stay and it was DS's birthday. Party on Friday, out to cinema (though only had water and two Cadbury fingers- couldn't fancy any more than that, a big change for me), Thai takeaway yesterday then birthday lunch and cake tonight! As I result I'm really looking forward to fasting tomorrow.

I had lots of family and friends at the party say I'm looking really slim (i hadn't told them about being on 5:2) which felt great as I don't feel that I look different and my clothes aren't really looser. I have lost nearly a stone since March, 8lbs from cutting out rubbish and nearly 5lbs on 5:2 (although not sure where I'll be after the weekend)!

As I've lost weight it's made me want to tone up a bit, so inspired by lots of you plus plenty of others on MN, I did the shred tonight. The abs killed me, but I coped better than I thought and actually felt really energetic after, but I'm shaking now and can tell I'll be sore tomorrow. Can't see I'd manage it every day but 3-4 days a week should be achievable. Once I've got used to it a bit more I like the look of lots of the other JM exercise DVDs to mix it up a bit (especially if I can find them on YouTube Grin).

HellesBelles396IsDeeplyUncool · 28/07/2013 22:16

I'm not including exercise calories TIP it somehow seemed slightly dishonest to include them rather than focussing on controlling calories in.

I usually weigh any food not in portions and use the scanner whenever possible rather than rely on what people have typed in.

Going 10% below would give 1812 a day to aim for.

HellesBelles396IsDeeplyUncool · 28/07/2013 22:19

WriggleBum adding extra stretches should help with shakiness and achiness.

If you are into dvd's and have Darcy Bussell's pilates one there is a very good ten minute stretching session on there. The whole dvd is a good rest day option.

wrigglebum · 28/07/2013 22:48

I don't have any exercise DVDs at all, but I do quite fancy a Pilates one so thanks for the tip Helles. I used to do a fair amount of exercise and weights workouts (I really love body pump), but just don't get the chance now with the boys. And I love a good stretch- should've been a cat!

Shakiness is going now and I'm feeling good! Wonder what effect this'll have on my fast tomorrow.

Just back from hols, marking place x

Hello. I am a newbie here. Today will be my first fasting day. I am excited, but a little worried that I won't cope with the hunger. I had a BIG weekend of eating and drinking and I think my body really needs this today, so I hope I will make it. I have planned to skip breakfast and have some soup (around 200 calories) for lunch, then some tuna and steamed vege for dinner. My DH has decided to do it too.

I have read the book (Michael Moseley book) and although I love the idea of it being for my health, I am really keen to lose some weight too. I lost about 10 kgs last year on a Paleo diet, and I plan to stick with the Paleo WOE but intermittent fasting sounds like a good idea (Paleo is very pro IF) too. My BMI is 29 and I really need to lose another 10 kg to get into the healthy BMI range. Unfortunately I have been overweight most of my adult life, so it I am not sure my body really wants to let go of that muchHmm. Is it realistic to hope to lose that much doing 5:2?

There's so much to read on Mumsnet about the 5:2, it looks like there's a huge amount of support.

Any ideas about ttc whilst doing the 5:2? I believe it to be safe, and of course if I get a bfp I will reconsider.But I do think some weight loss would be beneficial for ttc and if I do get pregnant (very slim chance as I am 46 years old).

Looking forward to reading loads moreSmile

Thank you Bssh Smile

Good luck, Hopeful! Are you posting in the middle of the night in anticipation, or are you in a different time zone (as I am)?

People, I had such an ugly weekend of eating. Fine during the day - finally getting better at getting some low GI protein breakfasts - but the evenings. Oy, the evenings. I drank too much, ate things I wasn't hungry for, the works. This morning I weighed myself out of morbid curiosity (yes, obviously, I KNOW) and I was back up to 62.5, which is where I was after a whole week of bad eating a fortnight ago, which means that I have yet again undone two weeks of eating well in a couple of days. And I know it'll come back off quickly, a lot of it is water weight etc (AF is to blame here too), but this is beyond a joke now; I first hit my "intermediate goal" weight of 60kg on 4 June, and I have basically just maintained since then.

I feel like I post this post at least once every couple of weeks, and since madness is doing the same things and expecting different results, I need to do different things.

So, I hereby pledge that Sunday - through - Wednesday will all be alcohol free days. I'm going to go back to my old diabetic management materials (I had GD with both girls) and stick to low GI/high protein as much as possible, and START EXERCISING AGAIN.

Because I want to look like you, postmanpatscat, and you Bsshbossh, and you Melanie and you ERD and you Betsy.
