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!

Crystal, hello! Goody, a local fasting buddy, everyone else is asleep when I need a kick up the arse.

postmanpatscat, you could always eat the mussaman curry I cooked last night, which the recipe book tells me comes in at 900 calories a serve? I, obviously, lightened it up a bit. But still!

Actually, I had a realization yesterday that sounds stupid, which is that eating to TDEE is eating a LOT. I had toast and cream cheese for breakfast yesterday, a big pot of ramen noodle soup and a muesli bar for lunch, the aforementioned curry, rice and two glasses of wine for dinner, and I was still well under. I have to wonder where on earth all those calories used to come from?

Fasting today, feel far more positive about this then I did on Monday. Discovered last week that I can still successfully go to my fencing class on a fasting day as long as I eat dinner beforehand, and then I'm not really hungry afterwards, so that's great.

CrystalDeCanter · 22/05/2013 02:33

Oooh Tortoise, hi, so good to have someone else in our timezone! How long have you been doing this for? Do you fast on work days or home days?

I'm doing my first fast today. Ok so far, although have had a Skinny Flat White which is probably 200cals alone. Also I can't STOP THINKING ABOUT FOOD. Am going to go and buy the book so I can read that and obsess a bit more. Also I need to get away from my pantry.

I'm interested to see if eating better (and not drinking so much) helps my pmt, for some reason I have one day a month where I'm absolutely in a RAGE all day, then wake up fine. It would a great relief if fasting and eating more healthily can help with that.

Tortoiseonthehalfshell · 22/05/2013 03:27

Work days; I tried on home days, but frankly after twelve hours alone with small children, not being able to have a G&T was just too traumatic. DD2 is eighteen months now, so it's all shrieking/tearing/crying all the time chez mine.

Skinny flat white: about 70 cals according to my calculations. Unless you drank it out of a bucket I suppose. That is also the only thing I have had. I'm finding that I get through the day on a skim coffee, a miso soup or two, and come in around 100-150 cals. Then I either have a nice hearty 350 cal dinner with DH (who is also doing this, but has more of a lunch than I do), or keep it down to 250 and have a banana or some popcorn before bed.

CrystalDeCanter · 22/05/2013 03:34

70 cals really? - ACE! May have another and get through this fast on caffeine alone!

I am actually pretty hungry now. Well, it is lunchtime. MUST. DISTRACT. MYSELF.

Oh god Tortoise, the 18 month teary phase - very trying. No wonder you can't fast on those days. Here have these Flowers

LickTheSpoon · 22/05/2013 05:18

Hey Crystal and Tortoise! Where are you guys? Thought I was the only one posting at bizarre hours due to time zones!!

FD today after botched attempt yesterday...my first fasting fail - boo. A friend invited me out at short notice. Food was involved. But if i didnt eat til gone 4pm, is that a mini fast? or a 16:8? or another of the quirky twists on fasting i have seen others mention?

This thread moves faster than I can read it - off to catch up.

Tortoiseonthehalfshell · 22/05/2013 05:21

We're in South Australia, LickTheSpoon - where are you? That is a massively unfair username you have there, incidentally.

Did you eat more than 500 cals for the day? Then it's a mini fast. I think it only counts as 16:8 if you do it regularly, otherwise it's just "forgetting to eat until the afternoon".

I hope I'm right about the 70 cals. That's what my fitbit tells me, anyway, and I'm sticking to it.

LickTheSpoon · 22/05/2013 05:52

Hehe. Sorry bout the username! it sums up my approach to life. :o)

Def more than 500cals yesterday, but eaten between 4-9pm.. It probably wouldn't have been much more than 6 or 700 but then I got all "oh I've ruined it - I might as well have a chocolate biscuit"! Stupid...

Doing better today but need to remember to keep drinking water.

I am in Taiwan. Back home to UK in a couple of weeks then off to NZ for 10 months, so I'll be back in your time zone by September!

CrystalDeCanter · 22/05/2013 06:03

Hi LickTheSpoon, how's the fast going today?

I've just eaten a small bowl of salad leaves (dahling) and about 1/2 a cup full of roast butternut squash and roast courgette, dressed with a couple of teaspoons of ricotta cheese & pesto. Basically a small side salad. Or starter . . .

Off to the library now to see if they have Michael Moselys book before school pick up.

Is the book worth buying? Have you all got it???

dines · 22/05/2013 06:06

Good morning everyone. Fast day here goin to try and keep busy so will be walking into town and bk after takin kids to school.

EagleRiderDirk · 22/05/2013 07:03

NFd today. For the first time I'm growling with hhunger early doors. Gonna try no snacks though

frenchfancy · 22/05/2013 07:17

Crystal there is far more information on the 20 mumsnet threads on 5:2 than there is in the book; However I have no problem with giving the great Dr M a bit of money as a thank you so I bought it (when it was cheap on kindle).

MizK · 22/05/2013 07:34

Thanks for encouragement virgin, got through it OK and am making lots of plans for next FD tomorrow, so in theory I'll be too busy to obsess over hunger!

Good luck today dines you'll be grand :)

NFD today, aim is not to go crazy although have woken up ravenous, eek!

Dotty342kids · 22/05/2013 07:45

aargh, bounce back up to 10st 13 today! Definitely a result of a very food based weekend. Wasn't particularly doing anything but a fair few sugary treats worked their way in.
Still, am back under the control of MFP and feel confident that I will stop the damage and, after a second fast on Friday, hopefully return to a downwards, rather than upwards, trend!

ChesterDrawers · 22/05/2013 07:56

Morning all, another fast day here and much needed after a bit of indulgence yesterday.

It was our wedding anniversary and I was treated to a lovely afternoon tea which was followed by homemade steak burger and chips with cheese and bacon, Belgian chocolates, champagne and mojitos in the evening.

No surprise that I am up 2lb this morning but I'm hoping with lots of water, a run and just a prawn stir fry for tea I can shake off the gain in time for tomorrow's WI.

Chipstick10 · 22/05/2013 07:58

Morning all. Fasted on Monday whilst going down with a cold. What a bloody stupid thing to do. Was sooo bad yesterday. Wicked headache. Felt so sick, couldn't get my head off the pillow till lunch time. I wouldn't mind but I didn't eat very healthily once I was back in the land of the living.

Miffytastic · 22/05/2013 07:59

Just had to come on after weighing in- lost 1.5lbs this week to a new low of 10st1 and 1/4. Thank goodness things are moving downwards at last!
I think this may be due to tracking NFDs more regularly in MFP and some wiser advice I got over on the 5/2 website forum. Hurray!

LickTheSpoon · 22/05/2013 08:01

dotty repeat after me: it is water, not fat, it is water, not fat! Couple of fasts and it'll be history either way.

Hi crystal - yep fast going fine. No food yet bar a couple of licks of the spoon (how appropriate) or fingers when feeding baby son. Only on a fast day could puréed carrot seem tempting ;o) Must drink water tho! Normally I'm so good but am being rubbish today.

I don't have the book btw. This thread and the gurus who post here are all I need!

LickTheSpoon · 22/05/2013 08:10

Well done miffy and hope you feel better soon chipstick.

Itsaboatjack · 22/05/2013 08:12

Well done miffy.

I've bounced back up since my low on Sat, I'm back to 11st6.4. So frustrating. That's 0.2 on since my last official WI last Wednesday. I know I was good last week, I know I went over TDEE at the weekend but was still under for the week as a whole, and did exercise on top too.

I'm hoping its water retention in my muscles as my legs are a little stiff from yesterday's run.

Another FD here today.

Dotty342kids · 22/05/2013 08:29

That's great Miffy, well done! Just what advice did you get over on the 5:2 forums......???
itsaboat - let's hope we both shake off the upward trend (though yours was very tiny) in a few days time Smile
And yes Lickthespoon, it must be water, not the chocolate and cakes I ate Grin

BetsyBell · 22/05/2013 08:31

Itsa definitely water retention in muscles [nods sagely] - I've got aching thighs from squats and running so my bounce up better be water retention and not the mountain of chocolate covered peanuts I ate yesterday (as pudding, not snack) Blush

I normally keep my squats to myself but today I did 80 of them, post-run in front of the kids who were most amused and then reluctantly impressed - so much so I received a reward token from DC1. No idea what the tokens are for but every now and again I'm asked if I would like cash my tokens in for a surprise gift.

Dotty342kids · 22/05/2013 09:09

Aw that's so lovely Betsy. My kids are decidedly amused by my Squat challenge efforts too but I've not had any reward tokens Angry. I'm up to 180 today which is going to kill me! Because we're on holiday next week (and I have no intention of doing them there) I'm having to miss out all the rest days. My poor knees are getting really sore!

Itsaboatjack · 22/05/2013 09:32

dotty it's up 2.2lb since Saturday but I record Wednesdays as my official WI day.

Up to 180 today, I'm not looking forward to that. I'm on 105 today. I'm gonna need the kids to watch me soon as I keep losing count!

Betsy I like the idea of gift tokens for squats, that's so sweet. It's a good idea though, we should plan something nice for ourselves if we make it to day 30.

wonderingagain · 22/05/2013 09:38

So I am down by 12lb in 3 weeks and missed quite a few fasts. Am on ADF so doesn't matter if I miss one. I am probably doing 6 fasts over 2 weeks. Hoping to lose 2 this week. I'm finding myself trying to save energy on NFDs, hopefully my uncinscious need to fail will pass.

BreakOutTheKaraoke · 22/05/2013 09:47

New low today, woohoo! 10.0.75...the nines are so close, I can taste them Grin. Hopefully hit that after the next fast, either Thurday or Friday!

Broke the fast this morning with 2 slices of white toast with proper butter and mature cheese spread, and a white chocolate cookie. Don't normally have dessert with breakfast, but I'm not snacking so had to fit it in this morning!
