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 recently unveiled a new 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.

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!

Morning all, glimpsed another new low this morning... 9st 4.4lbs , not sure how or why because yesterday was an eating day, not complaining though.

I was going to fast today but a couple of friends from the UK landed last night and we sat up until 1.30am catching up and quaffing a few bottles of Wine so the head is not the best , having a cup of tea, painkillers and then see how i feel Blush i'm such a lightweight these days.

Has anyone had a successful fast hungover?

SAF dont worry, chalk it up as a bad day, hope today is better for you.

headintheclouds · 27/03/2013 08:44

virginposter thankyou so much for your response and everyone else- its brilliant for motivation to hear your stories !21lbs is amazing .

dotty fantastic ,well done- you are spot on, we have to keep the faith and keep plodding on! It can be frustrating though cant it when you know you're doing everything correctly and the blardy scales do not budge( or budge in the wrong direction)

holidays Im off now for 10 days or so.We are travelling south to my mothers for Eaaster on Good Friday.So lots of family 'dos' involving chocolate / food/ wine. Im going to fast today and I intend trying my hardest to fit 2 fasts in next week as normal..but it will be my first experience of fasting whilst not being at work Hmm
Good luck everyone and have a great Easter break.

You can also listen to the interview here. Someone on the fast diet website says it's better if you listen.

Holding steady at 10st8.5oz. A few uppy downy bits. Hoping this is the level bit so I can now move down. Anyone noticing that their eating day appetite has changed, I just feel I can't eat massive meals anymore, and not that hungry. Would love weight loss to be moving downwards with appetite.

Dotty342kids · 27/03/2013 10:06

Yes, I agree minimammoth, I definitely don't eat as much on "eating" days as I used to. Or if I do, I then feel stuffed and uncomfortable. Definitely helping me to relearn what a reasonable amount of food actually is.

greenfig · 27/03/2013 10:49

Had a wasted feed day yesterday as was busy with the children so not nutritionally great & def not satisfying! Consequently felt quite reluctant about todays fast. DDs birthday on fri & out thurs eve so HAS to be todaySad Hey ho, just got to get on with it & stop eyeing up the fresh bread! Too many goodies in for the hols! It DOES make it more doable though knowing that it's only 1 day.
Re target weight, my initial one was set on Dukan website which seems quite realistic. It takes into consideration age, pregnancies, body frame & previous high & low weights. However, at that weight my BF% is still a little high although BMI is 22. Also we all seem to have put targets at round numbers, & I would like to see 9 again or even 8 something just for the thrillGrin I suspect that will actually be too low for me to maintain easily & make me look gaunt though, so would like to be able to stabilise between 9 & 9.4.

BsshBossh · 27/03/2013 11:49

dines good advice from virginposter about trying 4:3. Another idea to try is do mini fasts on your eating days - so eat in shorter windows eg 16:8 (fasting for 16 hours, eating for 8) or Fast 5 which is eating within a 5 hour window. There is only so much food your body can take at one time so the shorter window may help restrict your calories to your TDEE. I regularly do 16:8 on weekday non-fast days and eat between 2-10 pm and have found it's helped me not to eat over my TDEE.

BsshBossh · 27/03/2013 11:50

Dotty woo hooooooooooooooooo! Grin

ELR · 27/03/2013 11:55

Hi all decided to fast today instead of tomorrow and then will do a mini fast on friday. Went out for a curry and some drinks last night so went well over tdee.

I woke up this morning feeling pretty rubbish, don't think I can eat that kind and that amount of food anymore!

I've got a little bit of a hangover but had plenty of water and a black coffee, just going for a little walk now and then will eat something when I get back home prob porridge as that's gentle on the stomach i think! Then a gloriously skinny soup for dinner.

Good luck everyone who's fasting today.

sweetkitty · 27/03/2013 12:01

The weight losses on here are great so well done everyone. I'm hovering around 8.11 just now which I know isn't big but I'm small and very small framed, all my weight is on my bum and hips. I want to be 8.6 ideally. I think this would be ok 8 stone would be too skinny.

Bought a new bra today 34B, I used to be a 34C/D pre DC prob sane weight I am now. The B cup is still a bit saggy too I've lost so much weight from my boobs especially the top of them. Still they fed 4 babies in 7 years Grin

I also seriously need to get toned, I'm skinny fat love that phrase, seriously unfit and flabby.

Anyway fast day here going to clean the bathrooms before my weight watchers soup and banana lunch 150 cals!

Dotty342kids · 27/03/2013 12:04

Thanks BssBossh Grin

BsshBossh · 27/03/2013 12:05

greenfig that calculate your true weight thing on the Dukan site is fantastic, thanks so much for mentioning it.

postmanpatseasterbunny · 27/03/2013 12:22

Well done to those who have lost :)

greenfig your DD shares her birthday with me so I'm not fasting then either! Doing today instead as I also have plans for tomorrow.

My target weight makes me a comfy 10 rather than a borderline 10/12 which I am at the moment. We are all different shapes and at 9st 5 and 5ft 4 I really should be a 10 but they are still a bit tight around bum and hips.

postmanpatseasterbunny · 27/03/2013 12:27

Tried the Dukan thing...it reckons my true weight is 90g less than my target weight!

Guess that means it's achievable Hmm

BsshBossh · 27/03/2013 12:51

Grin postman. It gave my true weight as 1lb above my target. LOL. But at least I know I am on the right track. I'll take it with a pinch of salt at the end of the day but it's nice to have a guideline.

tracedw · 27/03/2013 12:52

Just tried Dukan too... my ideal in my head weight is 8st 5....Dukan was 8st 7 so not that far off.
I spent my 20's and 30's weighing between 6st 10 and 7 st 7 , my 40's between 8st and 9st..... but after having ds3 at 46 (my gorgeous pre-menopausal gift) i have been floating around the 10st mark, far far too much !
I blame the Wine
I'm 50 now and only 5ft 2 with a small frame so mid 8st seems a dream, i was 8st 5 before i got pregnant with ds3 so seems achievable to me.

Minimammoth · 27/03/2013 12:53

Postmanpat, I am 5' 4" too but showing 10.8. In my younger year I was always 8. 7. But feel that would be too skinny for me now. I would def. be jowly and saggy. Face or arse as they sayGrin I would like to Be about 9. 7. And not too saggy.

dines · 27/03/2013 12:55

Wots site isit that tells u ur ideal weight?

Dotty342kids · 27/03/2013 12:57

Yes, can someone please post up a link. The only page I found required you to give them an email address and sign up to receive all their promotional stuff!

dines · 27/03/2013 13:13

I done it and my true weight is 8st 6 was wot I was goin for.. all you need to do is put in dukan calculator in google

sarahandduck · 27/03/2013 13:22

I'm delurking to say hi. I've been doing this for about 6 weeks now and I'm not weighing myself at all....I exercise a lot, but was eating a lot too as I was always a curvy size 14/16. However, I am pleased to report that I have lost weight from my middle (I almost have a flat stomach!), I'm now a curvy size 12 and my bust size has gone from 36J to 34FF. All in all, I'm really pleased. I've bought myself some new undies and my first pair of skinny jeans. In a size 12!! Never thought I'd see the day. Oh, and I seem to have acquired 2 admirers which sure as hell makes those fasting days easier.

I love these threads and you are all inspirational.

dines · 27/03/2013 13:32

I started this woe at 9st and I am now 8st 9-10 which is not far from wot the dukan website said my ttrue weight was... my lowest on this way of eating was 8st 8 but its gone up and down.. but I still look like I have alot to lose, like in my belly area and the top of my arms.. if wen I get to my ideal weight I still feel I need more to lose wud it be best for me to start toning up rather then lossing more weight

frenchfancy · 27/03/2013 13:35

Dunkan Calculator here:

www.dukandiet.co.uk/en/350-subscribe.html

It put my ideal weight at 65.9kg, vs my goal of 67kg. I'm currently 68.3kg so not long to go Grin

Itsaboatjack · 27/03/2013 13:59

The Dukan calculator gave me a true weight of 10st 4lbs, which is 4lbs above my goal.

BsshBossh I'm going to try and do the 16:8 on my eating days, see if I can curtail the eating in the evenings, I don't finish work until quite late some days though so we'll see how it goes. I first ate today at noon so that gives me until 8pm to the end of my window, then I'll just have to try and not nibble when I'm at work tonight.
