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!

Well done BreakOutTheKaraoke! I'm hoping to follow in your footsteps this week - have been hovering above 10st for a few weeks now and am looking forward to sliding off this plateau in the 9's Grin

Was 10.2.6 on Monday and haven't fasted since last Friday, so am hoping that fasting today and Friday will get things moving again. I know there are a few of us trying to get under the 10st barrier - hello betsybell and others.

What are these squats of which you speak? They sound most uncomfortable, but the question is, will they reduce my enormous bottom??

BetsyBell · 22/05/2013 10:02

dotty If your knees are sore are you doing it right? Should be sticking your tush right out, getting (or attempting to in my case) thighs parallel with the floor which should, hopefully, stop the pressure on your knees

Yes the token was sweet Smile, we've had lots of conversations about fasting, commercial snack advertising/food industry and related stuff too, he's very interested. I must get him out for another run with me over the weekend, it makes for some lovely - and rare - one to one time. And Itsa totally agree, we should give ourselves a nice reward for completing the challenge! I might need a massage after all the exertions!

BetsyBell · 22/05/2013 10:05

BreakOutTheKaraoke · 22/05/2013 10:21

Thank you fatsatsuma! We can do this, kick that 10 in the arse!

CrystalDeCanter · 22/05/2013 10:23

Well done everyone on their mostly amazingly impressive weight losses.

It's my first day at fasting today and due to timezone differences its almost dinner time.

I'd just like to ask those more experienced at this, does the fasting affect your sleeping? I'm really hungry but it's only 7pm, if you eat your teeny weeny dinner now do you wake up hungry in the night or do you eat later than normal in the hope that you stay fuller longer?

Also is it ok to fast on two consecutive days? I'm going to a comedy show on Friday so would like to go there without a hungry headache, Sat we're staying with friends - could do Sunday I spose, but then I wanted to fast Monday . . . Any thoughts?

BetsyBell · 22/05/2013 10:28

Crystal The sleeping issues should get better after a few weeks. I sleep like a bay after fast days now (and I eat at 6 so I'm not full at bedtime) but the first 3 weeks I barely slept at all but weirdly felt absolutely fine on it.

I've never done a consecutive fast but lots do so it's definitely ok! But if I were you I'd just hold off and fast a couple of times next week - it's a lovely flexible WOE!

Missed your post Karaoke! Hey well done Smile

virginposter · 22/05/2013 10:32

Crystal i save all my calories for 1 meal in the evening which I eat as late as I can (between 7-8) and therefore am still fullish when I go to bed. I've been doing this right from the start and always have a good nights sleep on fast days Smile

postmanpatscat · 22/05/2013 10:41

wondering and miffy and karaoke you're doing great!

crystal chuck loads of veggies or salad on your dinner, then it won't be teeny weeny!

Fast day for me today, good job too since I slept late and didn't have time to do anything more than grab a can of soup as I passed the kitchen on my way out of the door.

Dotty342kids · 22/05/2013 10:48

Betsy, yes, my tush is definitely "out the back door" when doing squats. I can see my reflection in a glass door when doing them so know it's a decent technique. Think it might just be exacerbating a bit of a weakness in them as get twinges in them from time to time anyway Sad
Of course, it's not helping having to miss out the rest days but I'm really trying to avoid having to do them whilst in Marrakech next week where we'll be busy doing stuff and it'll be very hot!

CrystalDeCanter · 22/05/2013 10:50

Thank you Betsy, Virgin and Postpanpatscat. Interesting range of views. I'll eat a mass of veggies with my 1/2 doz prawns and see how I go.

BetsyBell · 22/05/2013 10:55

dotty I asked as I realised I'd been doing them completely wrong until a few months ago blush My knees do creak alarmingly though! Yes, you're probably overdoing it but for a totally understandable reason - bikini body Grin. Very Envy at Marrakech holiday and don't you dare do boring old squats while you're away!

Ooh, brunch time at last - planning a big one as no more food until 6pm today, baked beans on toast, maybe an egg too (NFD NoS day!)

Dotty342kids · 22/05/2013 10:56

Thanks for suggestion though Betsy and I'm still a long way off a bikini body - it's just something some of my zumba friends and I thought we'd give a go, though we're regretting it slightly now Grin

BetsyBell · 22/05/2013 10:58

Crystal Yes I always have a huge plateful of food on fast day - lean protein and masses of salad and veg - lime juice, fresh ginger and chillies go an awful long way to pep up the greens and leaves... I try and pack in as much nutrition for my 500 calories as possible, as a challenge and so I don't have to take vitamin supplements.

BetsyBell · 22/05/2013 11:01

Also Crystal prawns are really low calorie so you can have more than 6!

NoWayNoHow · 22/05/2013 11:04

Also trying to beat the 10st mark - what is it about that weight that wants to kick us in the teeth?

Did a cheeky weigh this morning and have lost 1lb, which is encouraging seeing as I only started this WOE yesterday, and even more encouraging based on how much wine I drank what I had over the weekend.

As a newbie, would you mind letting me know how you all spend your NFDs? Do you still calorie count? If not, how do you manage what you're eating, and do you still lose? If so, do you count to your TDEE, or another benchmark? Do you make a distinction between weekends and weekdays at all? (I only ask as I'm very much a weekend eater/drinker and weekday saint - normally!)

Sorry for all the questions, just really interested to hear how this works for all of you and what you all do differently!

BetsyBell · 22/05/2013 11:10

noway I don't calorie count but I do keep a food diary so I've got an accurate visual to see how I've been eating. Like you I keep it modest over the week but indulge a bit more at the weekend - always look forward to that Monday fast!

Miffytastic · 22/05/2013 11:23

Ah thanks folks Smile

Dotty - Caroline/Caroess over there did some maths and approximated my TDEE based on my loss over time (and it was more like 1700 than 1900 that I was using). So that suyggestion, combined with the encouragement there & here to track a bit more on MFP, has worked a I think

NoWay I am roughly tracking on MFP-ing all week for the last two weeks. Some days (weekends!) I forget and guess the next day, but I like the overall graph you can see across the week, it keeps things in balance, which is what this WOE is all about.

BTW, I came across this tumblr/blog the other day, I have never had hearts of palm, so will be trying that salad. Last night's tea was roasted artichoke hearts, a poached egg and a bistro salad, inspired by this

5-2veg.tumblr.com/

Dotty342kids · 22/05/2013 11:26

NoWayNoHow to start with I used MyFitnessPal to help me keep a track on my daily NFD calorie intake and that worked really well. Then I stopped using it as I got used to what 2000 cals vaguely "looked like". Over the last few weeks however, my naughty chocolate demon has reared its head again and I've become aware that I've probably been going over my TDEE on non fasting days. Also, as I've lost weight I've had to readjust how many calories I should be having on a NFD so I'm back to using MFP again for a while to help me make sure I'm not going over that too much.
I tend to be fairly "good" during the week and stick to TDEE or thereabouts but I definitely relax on a Fri night / Sat Smile and rely on my Monday fast to bring me back on track. I think of that one as offsetting any damage done by the weekend and my Thursday fast as the one that produces a little bit of weight loss!

Dotty342kids · 22/05/2013 11:27

miffy, that's interesting as that's exactly what mine has gone down to! Started at about 1900 cals per day and now, 10lbs lighter, I have just under 1700 per day to play with. Seems very unfair that the slimmer you get, the less you can eat but never mind Smile

ChesterDrawers · 22/05/2013 11:31

Oh god. I get chocolates delivered once a month, to nibble on now and then inhale in one sitting and they've only gone and arrived today when I am fasting.

I can have them tomorrow, I can have them tomorrow, I can have them tomorrow...

Itsaboatjack · 22/05/2013 12:09

Oh dear chesterdrawers hide them somewhere now.

postmanpatscat · 22/05/2013 12:17

noway I eat to my TDEE (1600) most days, don't eat back exercise cals, log everything on MFP and if I want an eat-whatever-I-like day, I'll have one! Have to admit though that there's only about one of those a fortnight, but with half term next week there will be many more!

dotty Marrakech sounds fab! Wet windy west country for me.

MummyPigsFatTummy · 22/05/2013 13:37

As a newbie (first fast yesterday) can I ask a question please, which I saw asked but not answered on Michael's Moser's site. I have hypothyroidism and am on HRT. I am also getting on a bit. It seems probable that I may also have a low metabolic rate compared with other people of my age and weight. Do you know whether that needs to be taken into account on fast days or should 500 cals still work? I dread to think how I would manage on any less but I do want to lose weight.

EagleRiderDirk · 22/05/2013 14:09

Oh my god I have the raging hunger still today. Its a feast day and all but I'm sure that doesn't mean eat constantly and never be full. WTH???
Am trying to channel all my fast day techniques into ignoring it. Have treated myself with a Cadbury's hot choc and thats at least satisfied me a bit.

EagleRiderDirk · 22/05/2013 14:09

mummypig I'm no expert but I'd guess that may mean you may not lose as quickly. Could be totally wrong.
