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 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:

All our previous threads can be found by browsing back through the 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!

Started watching Fat, Sick and Nearly Dead - WOW! I'm tempted to do it for my holiday in 6 weeks! He lost about five stone in 50 days. Will watch the other half tomorrow.

thinkcan · 11/07/2013 03:39

talking sorry I missed your post before I put in mine. You got it exactly right!

breakout. No need to apologize. I really should have included more info about myself when I decided to delurk. Also this business of converting US to UK sizes is rather confusing. The website I checked tells me US size 2 is UK size 4 but now I find out from the posts here that it's a size 6. Doesn't help that I am living in Asia where our clothes comes in all kinds of size measurements.

akarucker the reason many Muslims put on weight during Ramadan is because, although they fast from sunrise to sundown, the amount of food consumed out of those hours is often more than what they would usually eat. Also many cut down their exercise routines during this month. Having grown up in one Muslim country and now living in another, I know that many Muslims would wake up to have a full meal before sunrise and end each fasting day with a huge array of food. Even us non-Muslims look forward to the special treats available during the fasting month. Don't get me wrong - the fasting during Ramadan is not easy. It is just a very different kind of fasting from what we do on this diet, so don't get discouraged.

breadandwine I love your perspective on our weight fluctuations. All the more reason to focus on my nsv's.

mttum · 11/07/2013 05:13

Morning all, up early for (5hour) trip to London. Normally I'd have been stressing over what food to take on the train, looking for containers, rushing round generally. Today though, it's a fast day: bottle of water and off we go! Anyone else find that fast days can actually make life easier?

Regarding clothes sizes, and speaking as a bit of an outsider, they are really a bit of a red herring aren't they? I mean, I bought a pair of trousers from m&s yesterday, 34" waist, which I was pleased about because a year or so it would have been 38". But I know for a fact that my waist measures 40" all the way round Sad

babysaurus · 11/07/2013 05:28

Lurking so marking place even if I don't post much...

akarucker · 11/07/2013 05:36

Months in, and the sleepless nights continue to be a real problem on FD. I only ever manage about 4 hours (and no, that's not all my body needs because I am tired, tired, tired!)

mttum · 11/07/2013 05:42

Haha, except I forgot to take my phone and had to rush back for it!! Grin

AmericasTorturedBrow · 11/07/2013 07:28

Night all, 11:35pm here, fast done, hit cross buns out the freezer and banana bread in the cake tin untouched - looking forward to tomorrow Grin

SoTiredAgain · 11/07/2013 07:32

Heehee mttum that's the sort of thing I would do. Grin

Clothes sizes are a farce because there does not seem to be a standard between the shops. If every shop agreed to have the same measurements for a particular size then it would be much better for us consumers. I guess it's not a "size" but more of a guideline.

mttum · 11/07/2013 08:02

aka, it's horrible when you can't sleep isn't it? Is it a new thing then, as you only say its a problem on fast days? Are you still hungry when going to bed? I find it harder to sleep when I don't eat anything on fast days, but if I have a good meal about 7 it seems to be better. I have just ordered a book called "The Effortless Sleep Method" by Sasha Stephens for my father. It was highly recommended, although too early to say if it works in his case.

Beachcomber · 11/07/2013 08:05

Hi everyone. Marking place. FD today, hope I get on ok as stupidly had some wine last night sitting up chatting with DH and feel slightly hungover (am on holiday from work this week so justified midweek drinking to myself last night. Am regretting it now).

BsshBossh · 11/07/2013 08:16

Skinnyeye and Breadandwine - words of wisdom from the "old timers", thank you Flowers. I find my weightloss speeds up after a period of not controlling food intake. I think feast and famine cycles keep our metabolisms in tip-top shape (well, in my experience anyway). Also, my weight fluctuates 5lbs over a week but I don't stress about it at all.

HellesBelles396 · 11/07/2013 08:20

First fast day and my stomach is not thrilled about fruit for breakfast...

BetsyBell · 11/07/2013 08:21

Morning everyone, I woke up at 5 for no apparent reason (I suspect the naughty midweek couplaglasses of wine might have had something to do with it) so I'm going to be an excellent fun faster today! Feeling your pain aka...

Hopefully I'll get Dotty's burst of energy later, in the meantime caffeine is going to be my best buddy I think Brew

Good news, I sneaked a peek at the scales and I'm still holding my low weight so which very gratifying on the morning of a fast day!

NSV - decided I needed a new hoody type top as my usual one I use for running warm up/cool down just looks silly now (H&M size 14), and ended up with (though admittedly supermarket sizes)... a size 6! Probably should have borrowed one off my kids Grin

BetsyBell · 11/07/2013 08:25

Ugh, just remembered I ended up eating (snacking! Wine's fault again!) quite late so that's going to put the kibosh on my usual eating schedule Sad, will have to wait until after school rather than lunchtime I guess. Oh crumbs, I really am going to be fun today aren't I? Hmm

QueenBoudicea · 11/07/2013 09:19

Morning all - nfd for me today - yesterday's fd went well despite the rest of the family having homemade pizza for tea and icecream sundaes for pudding and the thought of homemade lemon drizzle cake in the tin!

No change on the scales for me. I've lost a lb in three weeks. My weight really fluctuates from day to day too so I'm never sure what weight to go for. I'm pretty sure I eat close to my TDEE and definitely stick to the 500 cals.

Am contemplating giving 4:3 ago - however I think I'd end up too wobbly and exhausted. Managed to get through yesterdays fd until falling asleep at about 9.45pm which is a break through. I did make sure that I drank as much water as I could which I think helped.

Good luck to all of todays FD'ers :o

Talkinpeace · 11/07/2013 09:23

Not doing 2nd fast this week - house guests - so will do extra swims and skip lunch while everybody else is out.
That and I walked miles with DD at her 6th form college open evening last night. My baby. 6th form. Aaaagghhh. I'm old!

Not sleeping : aka this time of year is really hard as the dawn is so early. Do you wear pyjamas? Unromantic but they help your body stabilise its night temperature. Also do your have really dark curtains and earplugs to block out the 5am blackbirds?

NB Ramadan : a friend is in Jeddah with work at the moment. Dawn to dusk is only 13.5 hours there. They wake up early EAT MASSES, sleep all day, get up at dusk EAT MASSES and party till gone midnight. Every day for a month. It has become a party rather than a time of abstinence. All the people she sees put on weight - and of course in Saudi, women cannot use gyms or pools or drive or cycle (she's not in the expat bit)

Dotty342kids · 11/07/2013 09:35

Morning all. Betsy I'm the same as you in that today's my second fast of the week but I'm still at my lowest weight so hoping that might see a new low either tomorrow or in the next week Smile
Someone up thread asked if fast days are easier somehow as you don't have to bother about what you're going to eat and when. I definitely do too! I suppose it's a mindset we could also apply to NFDs - just because we can eat our TDEE doesn't mean we have to eat it all in three meals, no harm in using it all in lunch / dinner or breakfast / lunch if we want?

Anyway, happy Fasting Thursday to all of us that are Grin

peplum41 · 11/07/2013 10:18

OOh another lovely day. Smile

Bread&Wine, thanks so much for mentioning the "Fat, sick and nearly dead" documentary, would've missed it if you hadn't highlighted it. I thought it was like the polar opposite of the Morgan Spurlock Docufilm "Supersize Me", but rather than damaging his health like Spurlock, he vastly improved it. And interesting to see the chaps involved not just losing all that fat, but their health being monitored by Drs, so you could perceive the health benefits too. Its helped me get my head together as been a bit out of the zone this week. Keen to fast today whereas Ive been reluctant to deprive myself in any way whatsoever for the last week.

talkin , your friend's thoughts on Ramadan are interesting, as in the shift away from a spiritual discipline to a party-on mentality. I wish id caught that ch4 item on it though. One positive side effect of 5:2, I watch much less tv.

Hellsbells, if you feel a bit off or desperately hungry later, it might be the fruit. Many of us have found that fruit, great on NFDs, is not so good as a breakfast on fast days as it makes you rather hungry later. So don't worry if you find it hard today, its not you! As you progress, try putting off breakfast as long as you can, think I can do another hour, and so on. The hunger comes in waves- just as it gets unbearable it eases and you feel ok again.

skinnyeye, really love to hear from seasoned fasters!

BsshBossh · 11/07/2013 10:19

Happy fast day, fellow fasters :)

HellesBelles396 · 11/07/2013 10:33

Exercise calories on fd's (unavoidable): bank or eat the resulting burned calories?

BsshBossh · 11/07/2013 10:47

Helles your TDEE (if you calculated it) should incorporate activity levels. So you'd not need to eat back exercise calories.

BsshBossh · 11/07/2013 10:47

Helles - Oh sorry, you meant FDs - no - stick to 500 cals, don't eat extra for exercise (most people on here don't, even if they exercise on a FD).

MissUnicorn · 11/07/2013 11:55

Hiya peeps
Well done on your loss Crystal
I'll have to look up this documentary, it sounds interesting. Fast day for me. I'm having yet another stirfry. I love them for fast days. Simple and healthy. Who else is fasting today?

BsshBossh · 11/07/2013 12:04

MissUnicorn I'm fasting today. Working from home as usual but so far haven't been tempted to eat. Aiming to break my fast with a vegetable curry and dal for dinner tonight.

Dotty342kids · 11/07/2013 12:13

I am missunicorn. Vegetarian shepherds pie with sweet potato mash for me later tonight....... Smile

BsshBossh don't get me all hungry with your curry talk again Grin
