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!

Hello 5:2ers, new and experienced.

dotty I tried challenging bsshbossh to a plateau off, but fell at the 3 month hurdle, suddenly losing 6 lbs for no good reason. I really struggle to eat within my TDEE, and seem to be losing about 2lbs a month now. It will do.

It's not me, its the ghrelin. On toast. With jam.

HellesBellesThinksSometimes · 12/09/2013 06:16

Grin Peplum

BsshBossh · 12/09/2013 07:24

Helles thanks for the info. I will read more about it. There's also the hormone leptin that's involved with hunger and fullness. Lots for me to learn :)

FD again today? Who's with me?

HellesBellesThinksSometimes · 12/09/2013 07:28

Me - after I hit tdee on yesterday's fd. Pesky ghrelin!!!

eatriskier · 12/09/2013 07:32

FD here too. It will be successful! I have my food planned (thanks to Monday's failed fast).

So is it ghrelin (gherkin as autocorrect prefers) or leptin that is responsible for me being hungry at 5pm every day despite the fact I never eat at 5pm? If I can find the reason for that and slap it into oblivion I reckon I'll be far happier Wink

Itsaboatjack · 12/09/2013 07:42

Well I didn't fast in the end yesterday, decided we'd have a few drinks with friends last night for dh's birthday so thought I'd better eat if I was going to drink, ended up drinking rather too much wine though. It was a really fun evening though. Going for dinner tonight with bil and his wife so FD will have to be Friday now.

BsshBossh · 12/09/2013 07:58

I keep wondering if we get to a certain weight and just 'stick' there - headintheclouds that's very interesting. My famous 4 month plateau last year occurred when I hit 11.5 stones. That was the weight I'd been for more than a decade! It was obviously my body's comfortable weight; the weight it had grown accustomed to. Dotty have you stalled at a comfortable weight your body is familiar with?

postmanpatscat · 12/09/2013 08:01

Morning all

Congrats on your NSVs hitc :)

Hope today's fasters do well. I fasted last Saturday so that will do me for this week. Away in Bournemouth this weekend for staff bonding so no fasting there. I've been hovering within 500g (either way) of 51kg for the last six weeks regardless of food intake, fasting and exercise it seems so that will do for me.

saf hope your new term madness eases off soon. Sadly I fear mine won't!

BsshBossh · 12/09/2013 08:02

Okay, I've been skim-reading about ghrelin and leptin (the two "hunger hormones") and the evidence is contradictory and inconclusive (and complicated!). The best predictorof keeping weight off in the longterm appears to be... drumroll... self discipline. Damn!

BetsyBell · 12/09/2013 08:15

Self-discipline eh Bssh ? Ugh Wink

Need to find me some of that on NFDs at the moment...

Talking of which, I think I'll do another fast day today!

Not sure ADF is actually a good way of getting back into the good old mode of self discipline but needs must for now. I'm hoping next week will bring a normal 5:2 week with sensible eating on weekdays. [sigh]

Promised DS1 we'll make custard tarts at the weekend... Can you tell we watch Bake Off together?!

Dotty342kids · 12/09/2013 08:18

BssBossh I have indeed stalled at a weight that I would say is the one I've often stabilised at in the past. So you did the same? What kick started the loss again for you?

hitc I'm sure you'll be looking fabulous for your trip to Venice and what a lovely thing for your DH to say Smile

peplum that really made me chuckle! If I lose 6lbs suddenly I'll be thrilled!

Down another belt notch today - that's three notches since I started in Feb - marvellous!
Fasting today and realised that TOTM's arrival yesterday may have caused me to remain the same this week. Really, really hoping for just 1 measley little pound lower tomorrow!

Dotty342kids · 12/09/2013 08:19

Betsy, you're a brave woman, those custard tarts looked impossible! Though presumably you'll have the full set of recipe instructions Grin

BetsyBell · 12/09/2013 08:27

I'm reinstating my food diary, maybe that will help me get back on track on NFDs.

Haha, just remembered hiding in the utility room yesterday evening so I could secretly eat some fudge I'd forgotten I'd left in my hand bag. I mean fudge? What am I doing buying fudge anyway? It wasn't even nice.

Here's what I'm aiming to get back to:

Weekdays:
2 fast days
3 sensible eating days with no snacks (especially not crap fudge)
No booze except Friday

Weekend:
Relax
Allow booze
Interesting baking

It used to work so well!

Like Tip said upthread - I fast not because I am overweight but because I don't want to be overweight again.

(I do want to shift another 7+ pounds though...)

All about me me me again - sorry! Bit stream of consciousness while I sort out a PLAN! Thanks for listening Grin

BetsyBell · 12/09/2013 08:30

Dotty I favour the Portuguese type with the slightly chewy pastry. Mind you, knowing me I'll ignore all the instructions, make my usual pastry and hope for the best!

eatriskier · 12/09/2013 08:41

betsy love the idea of interesting baking. sounds a bit like interpretive dance. I shall show you how I'm feeling through the medium of interesting baking...

SchrodingersFanny · 12/09/2013 08:43

I'm fasting today. I'm really tired after three days at work, year 8 nearly killed me yesterday! But a day with the kids today, so hopefully a bit easier!

Dunno what to have for my dinner, I have a recipe book but I'm always so tired!

BetsyBell · 12/09/2013 08:48

he he eatsriskier so true! After a session of interesting baking I often say "hmm, not sure how this will turn out actually, will probably be horiible" and my DH always gets very excited, knowing that's the sign it'll be something amazing!

Apart from the Chelsea bun incident [weeps at memory].

Right, I am fasting today so I'd better stop thinking about baking :)

OP posts:
BetsyBell · 12/09/2013 08:50

Shrodingers I work in a school - have instantly come down with a sore throat and earache, it's only been a week! And I'm part time! Am absolutely exhausted already.

What kick started the loss again for you? Dotty I honestly don't know. I stalled September to December then unfathomably lost lost 2lbs over Christmas and New Year. I'd stopped calorie counting over the Xmas break but DH said he'd noticed I naturally ate less than usual over that holiday period. I started exercise and 5:2 a month later so I can't put it down to that. It's mystery really.

BsshBossh · 12/09/2013 09:15

Betsy that's exactly the plan I follow. Simple and effective!

BsshBossh · 12/09/2013 09:17

TheWickedBitchOfTheBest welcome! Sounds like you've got the hang of 5:2 already :)

TheWickedBitchOfTheBest how much you lose depends on how much you have to lose and how many calories you burn/consume over the week. It takes a 3500 calorie deficit to lose 1lb. I don't calorie count but tend to lose on average 1lb a week on 5:2. My reading around suggests that that is the average loss for this way of eating.
