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!

no judgment from me bvb - ds will not eat anything complex - i couldn't say make a sausage pasta bake. i'd have to cook the sausages and whatever veg i was doing and the pasta and serve his all up separately on a plate Hmm if i served him the same ingredients but mixed together with a sauce he'd be like errrr i don't like it.

he also doesn't eat potatoes really which rules out a lot of meal options (i'm not a fan either so no great loss). at least once a week he has spaghetti with scrambled egg and veg which he loves and tbf is a nutritional balance - just one that no one else would eat. so def no judgment from me. i get in a balance of iron, protein and carbs and nutrients any way i can - and tbh what does it really matter so long as those nutrients get in there?

sorry bit off topic!

'food hangover' really rings bells for me. either i didn't used to feel crap from eating crap or i was so used to it i didn't notice. i now do notice.

BetsyVanBell · 24/03/2013 08:41

SaF yes that sounds very familiar!

BetsyVanBell · 24/03/2013 08:43

Aftereights - brilliant news Grin

melbie · 24/03/2013 09:00

Aftereights wow!

I shall go in hunt of lettuce and other yummy salad things for my next fast day. Have also rediscovered stock in hot water as a sort of cup a soup- very filling! I have had that before on diets as a crisis solver and it has taken away the hunger pangs enough to get me through the evening I think

SpiralSkies · 24/03/2013 09:21

I'm fascinated by the people who have gone off alcohol - I wish the same would happen for me! I've definitely cut down my weekly consumption but can still easily drink a bottle of wine on a weekend evening. I do love a good glass of wine or three! But... I've noticed that I never, ever get hangovers anymore. I suspect my body is now simply working more efficiently.

Minty I'm another one who really doesn't lose much weight. But, strangely, I have twiddled about with things (again) (lowering weekday intake and going over TDEE at weekends) (yes, wine Blush) and have somehow dropped 7lb in 3 weeks.

To people just starting out on this, wahooo! You are doing something brilliant for yourself! I think, in a holistic sense, this way of eating is all about listening to your body and being kind to yourself. PMS making it impossible? Fine, just have a few extra calories. I've certainly been going over the 500 cal allowance on fast days - although I do fast for a good 20 hours before eating my cals so as to reap maximum health rewards. These long, cold days and, as someone else has said, being simply sick of winter veg, are playing havoc with us!

Bramblesinafield · 24/03/2013 09:23

Well done after eights!

I'm back on track after a week away. My weight went up slightly, but its back to the lowest point and I hope that after a couple more fast days that it will be continuing on the downwards trend.

Dh actually noticed the difference yesterday which kept me going when fasting on such a cold day. Actually, hogging a log fire is a great way to stay warm!

Next one tomorrow.

Bramblesinafield · 24/03/2013 09:25

Keep going minty! Will be interested to hear what your gp says.

Also a soup fan. If I have soup on non fast days it helps - bread, I've discovered, really bloats me. My dh is coeliac, so eating fairly gluten free is not a problem in this household.

mummyof2girlsx · 24/03/2013 09:44

Morning everyone, I have been a long time lurker and have stating posting occasionally over the past week or so. Just to say well done and thank you for these threads as they are so informative and encouraging!

I am going to revert back to just lurking rather than posting though as no-one seems to reply to my posts lol! Blush

Good luck to everyone fasting today Grin

SpiralSkies · 24/03/2013 09:46

Mummyof2 I'm sure your posts aren't deliberately ignored :) These threads gallop along at such a pace, it's almost impossible to keep up with it all!

Keep posting! How are you getting on?

GreenEggsAndNichts · 24/03/2013 10:00

mummy as Spiral says, these threads sometimes are moving really quickly, it just depends on what's being said, and who is around. I quite like having time to respond to most people, but with the number of new posts sometimes I just respond to one or two.

melbie I find soup good on fast days, very filling. I also loved salads on fast days but I think they require better weather than what we're having at the moment!

Welcome back aftereights, great news from the Dr. :)

OP posts:
mummyof2girlsx · 24/03/2013 10:23

Thanks for your replies Smile

spiral I am loving this wol! Started in November and now nearly at goal weight so hoping to maintain, I do my fast days during the week as I find it much easier to fast when I'm working and like to relax a bit at weekends Wine

As I said I love these threads as I find them great for tips, recipes and they encourage me to keep going when I'm having a tough fast day Smile

swallowedAfly · 24/03/2013 10:25

i'm afraid i'm pretty useless at responding to people. i come on first thing in the morning when i've missed lots of evening posts (i go to bed early) and have to just skim read and respond to whatever stood out. then after work i do the same.

i'm also very self absorbed and tend to just see the things that are relevant to me or that i can answer as i've had a similar issue or something. i also know there are others who are way better at patiently answering questions than me.

i'm afraid working, single parenting a 6yo and dealing with the mayhem of two dogs and a cat leaves me with not much attention or energy left over Grin apologies if i have seemed rude.

BetsyVanBell · 24/03/2013 10:31

Hello Mummy I had been trying to respond to everyone but have got a bit lost in the last couple of weeks. Please post up any questions again :)

Spiral Damn, wish it had happened that way for me! However, it might jus be a phase, my body does go through them and in the mean time it's no bad thing to cut it out for a while I suppose Confused.

Melbie Yes, another vote for real food here! I try and make my 500 calories as nutritionally varied and dense as possible which in reality means several veg types and lean protein - usually skinless salmon fillet or big prawns or eggs (poached in soup, hard boiled or as an omelette with lean ham & lots of fresh herbs), and lots and lots of zingy flavours like lime, ginger, chilli and garlic, fresh herbs go a long way to dress up some boring steamed veg too. It's all very quick cooking too so less time in the kitchen. Or of course innocent meal pots, glorious soups etc etc for even less time in the kitchen. Oh and a can of cooked beans or chickpeas livens up a soup or stew dish whilst adding lots of goodness. Oh and veg curries too! Yet another tip if you're cooking a pasta dish for the family is to cover your plate in masses of baby spinach or other soft leaf salad and add sauce to that instead on of pasta. I find it helps to have a full plate in front of me - helps satiate my brain as well as my stomach!

BetsyVanBell · 24/03/2013 10:33

mummyof2 crumbs, I hope that didn't come across as patronising! You've been doing then far longer than me Blush

mummyof2girlsx · 24/03/2013 10:38

saf no you haven't seemed rude at all, I see how fast these threads move and posts are easily missed. I know what you mean, I have a 6yo and a 4yo and I work and dh works away so life is pretty hectic!

Any ideas of fast day meals to take into work would be appreciated, I usually have soup but looking for some new ideas.

mollysfolly · 24/03/2013 10:51

G'day everyone! Remember me? Returned from fabulous holiday in NZ over a week ago and it's taken me till now and being snowed in for 3 days to catch up 5 threads! Firstly, lucky kiwigirl and wildwater to live in such a wonderful country Envy

5:2-wise, put on 4lbs in the 6 weeks we were away (good) and another 3 the week we got back (bad), so back to fasting Mondays and Thursdays - quite a relief actually to get back to normality!

B&W frenchfancy talkinpeace good to see you're still around and dispensing good advice. Are you still around laska ? Actually I'm a bit sorry blackmaryjanes has dropped out - she made me laugh!

Such a lot of new people - good luck with the Fast Diet - it works!! Smile

postmanpatscat · 24/03/2013 10:55

Morning all!

Didn't think I had a food hangover until I read today's messages. A gym visit yesterday and having taken a bulge out of the ironing pile meant I had loads of calories going spare, so when DD wanted chip shop chips I joined her! Egg and chips for us (a large portion between all three of us and there were plenty to go round) and this morning I struggled to wake up even at 8.30, feeling quite thick headed. I don't drink at all so definitely not that, but maybe it was the chips that did it!

Still under 60kg and fasting tomorrow so hoping for a new low on Tuesday.

DP has come to the end of his first week on 5:2 after 6 weeks of relentless exercising and calorie restriction while away in Oz, he cannot get to grips with eating 2200 calories 5 days a week because he feels guilty!! I keep telling him it's the weekly deficit that matters but it's not sinking in yet. He is terrified of undoing all that he has achieved (2st lost and back to the weight he hasn't seen for 20 years!). Any tips for brainwashing him welcome! Grin

mummyof2girlsx · 24/03/2013 11:14

BetsyVanBell not at all patronising, I have been doing this a while but I'm by no means an expert!
My problem is that I am not a great cook so I am finding my fast days consist of soup, soup and more soup!

postmanpatscat · 24/03/2013 11:19

I'm not a great cook either. How about throwing some prawns into half a bag of prepared stir fry veg and adding soy sauce? I do this with quorn pieces as I'm vegetarian.

mummyof2girlsx · 24/03/2013 11:43

Thanks postmanpatscat I will try that, sounds lovely, and a nice change from soup Grin

I can relate to the food hangover, last weekend went out for a meal with DH to celebrate our wedding anniversary and ate 3 courses, plus Wine...followed by more Wine! Felt uncomfortably full and a tummy ache the next morning too!

VivaLeBeaver · 24/03/2013 11:55

I'm finally taking the plunge and have started this today, so first fast day.

I had a cup of black tea with sweetener this morning and have just now eaten a pear as I was starving. Don't think I'm going to manage keeping under 500 calls for the day....that pear was probably about 60?

I'm not very organised, haven't read the book yet so will do that this afternoon. Am planning on having weetabix for lunch and then salmon with a load of veg for dinner. Haven't even worked out calories.

I'm so hungry.

Southeastdweller · 24/03/2013 12:01

viva Were you planning on being at home all day today? What are you doing apart from reading? My advice is to get busy and maybe go out for a walk or go to the library? Maybe do some gardening too?

TheEarlyBird · 24/03/2013 12:04

Hi Viva. I think I recognise you from the low carb thread :) . I can't possibly go for the full 36 hour fast but I am going from 6.15pm - 6.15, so 24 hours instead, twice a week and am continuing to low carb the other 5 days. Early signs are good so it might work for you too! On my fast days I am only eating low carb/low cal food so this week I had a monster bowl of homemade veg soup and an egg. I will know better how well it works when I've done a weigh in on Wednesday but am about 3lbs down already so very pleased (and it's not been too much of a struggle ........)

ELR · 24/03/2013 12:13

Hi everyone can't believe the new thread is on page 7 already! I'm still reading I'm on pg5!

Was my birthday yesterday so have eaten and drank loads and looking forward to fasting tomorrow.

I love this reading everyone's posts and find them really inspiring.

I think it's best to avoid responding to negative posts/posters as it only fuels their negative comments giving them a chance to continue.

B&W enjoyed the link about ageing, thanks. Def agree with the low gi way of eating.

I noticed quite a few people are 5ft4 and so am I my frame is medium.
My starting weight was 10st13.5(christmas weight)and am now down to 10st8, hoping to get to 9st5 however I have never been that low and have a classic hourglass bodyshape so look good at 10st10 which I have been give or take a few lbs for last 10 years or so.
Lowest I have been is 9st12 after a bout of food poisoning in India but lowest I have achieved normally is 10st1.5.

This is by far the easiest diet I have done I always follow a low Gi diet on both non fasting and fasting days.

Anyway enough of my waffling! Hope everyone enjoys the rest of their weekend.

VivaLeBeaver · 24/03/2013 12:15

southeastdweller. Ill take the dog for a long walk this afternoon so that will keep me busy and burn a few calories.

theearlybird. I haven't low carbed for years, don't remember going on the low carb thread but its possible from years ago. In fact most of my current diet is carbs, carbs, carbs. I did post a few months back saying I needed to cut down on carbs but then never did anything about it. Blush. Well done on your 3lb weight loss.
