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!

Likeahurricane. Your post is very interesting!

All my fat sits on my belly. I am a size 12 but belly is a size 18. Sigh.

Been low carbing all year with very little result. I still eat way too much.

I came to this thread looking for information on doing 16/8 which I have tried for the last 3 days and I can easily do. Not sure I could do 5:2 as I would eat all my 500cals in one sitting at lunch and not make it through the rest of the day.

Has anyone started 5:2 "softly" and done initial fast days with say 1000cals and worked downwards??

swallowedAfly · 03/08/2013 17:45

seem to recall people doing it that way mrsF - can't remember who it was but i remember someone keeping on trying but always ending up at about 700cals at the end of each fast day at first. if easy into it feels right to you do it!

i'm starving! have just cooked a mini toad in the hole for ds' dinner - no temptation there as it's not my thing but opening the fridge is a nightmare as it's so full of yummy picky stuff at the minute.

nearly 6pm. thinking marmite drink at 6, an incredibly light bit of salad with lean protein of some variety (probably the mini eggs my young chooks have started laying) after then soup in reserve for later on. should be less than 500 i think.

MrsFlorrick · 03/08/2013 18:06

Swallowedafly. Thanks. I will keep on with my 16/8 as I find that easy. And then ease myself into a fast day with 1000cals which I am confident I could. As it would be two small meals for me.

I guess Monday is a good day to start. Yikes fast day here I come!

HellesBelles396IsDeeplyUncool · 03/08/2013 18:29

MissStrawberry I recognise the ease of having a single "normal-sized" meal on a fast day but tend to have 2 or 3 meals on fast days. A typical menu would be a boiled egg for breakfast, chicken salad (no dressing) and a couple of spoons of good quality low-fat yoghurt, steamed fish and veg for tea, one chocolate truffle. Comes in around 500 calories with strict portion control on the chicken and fish, not so strict on the veg (basically as much as I can face eating). I spend most of the day feeling full. Michael Mosley has two 300cal meals a day so you can use your calories however best suits you. If waiting til teatime doesn't work for you, try having two meals on your next fast day.

MaisieMama Do you tend to put muscle on easily when you exercise? I have, in the past, put on weight while slimming down. What's happening with your waist and other dimensions?

MissStrawberry · 03/08/2013 18:44

I gave in and had tea at 6pm after having some salad with the kids at 5. Proud I told DH to take the 2 pieces of garlic bread away that he had put on my plate though. I am a bit annoyed with myself as I feel I had about 3 mouthfuls more than I needed but hey, it is day one.

I would be happy to have a salad wrap for breakfast and then a big plate of veg for lunch and dinner but don't know if that is sensible on fast days.

Feeling really full after my bacon lasagne and thought I was looking forward to tomorrow's roast dinner but actually feel stuffed at the thought of it ConfusedShock.

HellesBelles396IsDeeplyUncool · 03/08/2013 18:55

Well done MissStrawberry garlic bread is a difficult foods to resist. You were aware of your body's signals which is a big help.

Make sure you're getting low-fat protein as well as the veg. It's far more filling. A lot of people tend to skip starchy foods on fd's - not enough flavour and not filling enough for the number of calories used up by them.

Glad today has gone well. Just close the kitchen down and enjoy :)

swallowedAfly · 03/08/2013 19:14

well done missS.

i just broke my fast with some salad leaves and cucumber and some of the cute practice eggs from my hens which was all delicious. i love the way food tastes when you've been fasting all day Smile

think i've had about 200cals (seriously tiny eggs), 250 at most and there is canned soup in the cupboard and those crab stick things in the fridge so some low cal options for later if i need them but as ever i'm tempted to just say actually that will do. always feel like that after i've finally had my mini meal but usually change my mind by mid evening.

swallowedAfly · 03/08/2013 19:15

seriously though i don't think anything has tasted SO delicious in ages! probably since the last time i fasted and yet it was only egg and salad Grin

MissStrawberry · 03/08/2013 19:23

200 cals Shock.

I feel fine about nothing else to eat tonight, just keep drinking the water.....

swallowedAfly · 03/08/2013 19:26

i'm more than likely not finished eating yet missS. i prefer to start small and leave wiggle room.

well done on your first fast Smile

Talkinpeace · 03/08/2013 19:52

New Scientist Article this week about the inequality of calories and how the food you eat actively interacts with your system

interestingly high protein, low fat meals are an appetite suppressant

also, v v v interesting for people like mintyy who had absolutely no joy, even though her DH did, there is a protein marker called GPA120 which when switched on makes you store fat and because they now understand more about it, its only a few years till they find how to switch it off.

Those of us who have been on these threads a long time know how frustrating it has been for mintyy to not lose weight, and how ever more apparent its been that she has a genuine medical issue underlying her weight.

So all the crap about willpower and calories in / calories out just does not apply to some people
BUT medical science is advancing all the time and the detailed personalised medical treatments are now starting to come on line

MissStrawberry · 03/08/2013 19:56

I have chocolate and sweets in the cupboard. I would like some as they are nice but I am not hungry and have said I can have some tomorrow if I really want them.

Tomorrow I will be doing a roast dinner at lunch time with chicken. I can easily pass on breakfast, will have the lunch but then what do I do about tea?

I have managed pretty well today but I know if I did eat in the morning it would just set off needing to eat again and again.

Also, when to weigh myself? I know what I was the other day and I know what I am now but I can get daft about weighing and be on the scales every day.

Talkinpeace · 03/08/2013 20:02

missStrawberry
scales ; count the weigh in once a week, no more. I do every friday morning after my swim and before yoga, at the end of a week of control
I know that I weigh 3lb more on a Monday. Blahhhhh

Meals : eat if you feel you need to
all four of us (me, DH and two teenage kids) had a huge brekkie and then lasted till BBQ blowout supper
if my kids are hungry they raid the fridge, but they do not eat to alleviate boredom. I regard that as FAB

MissStrawberry · 03/08/2013 20:07

I'm not hungry but I am thinking too much about food. Not bothered about the roast tomorrow but would like some milk bottle sweets or some chocolate. Tomorrow though. Not now.

Talkinpeace · 03/08/2013 20:10

Miss
OK you need to start planning meals. Seriously. think about food but in a "that is in three days time" mode
as you have to separate emotional need for food from physical and detailed (ocd) forward menu planning is the best start

MissStrawberry · 03/08/2013 20:18

Tomorrow - normal day so will have roast for lunch and salad for tea with a bit of left over chicken.

Monday - would have tried fasting but arranged to go out with friends and she wants to get doughnuts after the activity so have to be a normal day.

Tuesday - fasting again - will have soup and salad.

How does that sound? Confused

I love cooking, I love choosing things to make, get cross sometimes not enough meals in a day to cook everything I want. Kids love me as I am often baking for them and often make them ice cream too.

swallowedAfly · 03/08/2013 20:21

i'm terrible at meal planning and hate cooking which really doesn't help me.

know what you mean about the cupboards missS there are some stupid mini chocolate donuts in ours at the moment that ds talked me into buying yesterday. i've just eaten a few crab sticks for a bit of flavour and texture - only 18cals each. i have about 150 left if i need them but am now craving crap rather than a bowl of soup. aargh.

i've brought myself to bed with a big glass of water and will try a cup of redbush tea in a minute - that's a good tip by the way for people who find they're constipated after a fast day - redbush is what they give babies with constipation in south africa and it's good for getting things moving gently.

right. must.avoid.the.donuts.

Rufus43 · 03/08/2013 20:32

Hello, can I join? Just finished a juice diet for four days. I have had a treat day today but I am going to try and eat better from tomorrow.

I plan to fast on Tuesdays and Thursdays, unless something does up in which case I will change the days round

The only two issues I have is that over the next week I may put on a few of the pounds lost through juicing and I am on holiday from the 9th for nearly two weeks so may find fasting a smidge difficult even though I will try to eat well!

Ought to do that sodding shred as well!

MissStrawberry · 03/08/2013 20:51

Donuts are always disappointing. Over too quick, give you bloat and aren't worth the calories.

I think what would be good is stop thinking of certain foods as treats. Sausage rolls, junk food, etc etc. Makes them immediately more attractive.

Breadandwine · 03/08/2013 20:53

Hi and welcome MrsFlorrick - and all the other newcomers to the thread!

Has anyone started 5:2 "softly" and done initial fast days with say 1000cals and worked downwards??

I began in Feb 2012 by halving my calories twice a week - so 1200 calories, roughly (I'm a bloke Smile). I lost about 8lbs in 5 months, so not a great loss - but I didn't know I had any weight to lose. After the Horizon programme I went down to 600 calories and lost a further 14lbs in a couple of months.

I've now been maintaining successfully for about 9 months (on 6:1, mainly) and have no intention of ever giving up IFing.

I've blogged about it here:

nobreadisanisland.blogspot.co.uk/2012/02/eat-less-live-longer.html

So yes, it's perfectly doable to dip your toe in the water and find out what works for you.

ATB, B&W

Talkinpeace · 03/08/2013 20:57

rufus welcome
the main thing to hold in your head is that this for ever, not just till you hit "target weight"

old hands like B&W and myself - I'm a middle aged mum, he's a mature grandad - are here supporting you all because on fast days we are all equal no matter what the BMI, age, sex, anything
which is what makes 5:2 and all variants of IF so sustainabale

MrsFlorrick · 03/08/2013 21:21

Breadandwine. Thank you Thanks or should that be Wine.

You have really encouraged me. I know I can do 16/8 as I have been for several days. And I would then only eat two meals in my 8 hour window. This makes 1000 cals doable for me initially. I looked up some recipes tonight and I can easily do this. Getting to 500 cals and a proper fast day will require some work...

I have restarted 30 day shred. I completed it about 6 weeks ago but need to firm up some more and I found it effective.

Anyone else doing shred or similar with IF??

alwaysanauntie · 03/08/2013 21:30

feggy my GP actually does 5:2 as well as he wants the health benefits, was quite reassuring to hear that!

smelly hope you are/have enjoyed bestival, saw it on local news today and looks great, loads of kids - will have to go when DD is a bit older. How was your appt? I've got mine on Weds to check out a lump and am trying really hard not to massively overeat with feeling a bit sorry for myself. I keep reminding myself I haven't felt this good in ages, so would be mental to waste all the hard work...

Mrsflorrick I started with more cals (600-900) to ease myself into this woe, and if I'm feeling rough often go up to 1000 cals on FDs, BUT I always skip breakfast on fast days and generally have salad with prawns (80cal) and maybe an apple (80 cal too) for lunch if I'm really hungry and/or exercising then a decent dinner (perfectly possible for 340 cals eg: small chicken breast, boiled sweet potato and lots of green veg. (& am still loosing 1 lb a week). Even FDs don't have to be about deprivation :)

MissStrawberry · 03/08/2013 21:35

Trying not to give in

Feels emotional or just eating for the taste eating though rather than hunger.
