The continuing thread for those of us following the 5:2 fast or other forms of fasting such as 4:3, ADF, or daily 16:8.

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 normally - or approximately your Total Daily Energy Expenditure (TDEE - see explanation below). 4:3 is the same except you fast on 3 days in the week. Alternate-day fasting (ADF) is just how it sounds; you fast every other day. 16:8 is another form where you stick to only eating in an 8 hour window each day, therefore fasting for 16 hours each 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.

NFD = Non fast day

NSV = Non scale victory

Michael Mosley has a website to accompany his book on the subject. Please go check it out, as he's the whole reason most of us are here!

Lurkers and new starters: please just jump in and post - you'll find a lot of support here and we’re a friendly bunch.

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 the 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.

This link nicely demonstrates that there are many body ‘right’ body shapes and types, because what we are actually aiming for is low body fat for fitness and 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!

Welcome, coffee We find it much easier to have non-consecutive FDs, but 5:2 should work with a double FD.

Full Monday+Tuesday FDs would mean about 60 hr fasting:
-last full meal Sunday evening
-500 cal Monday
-500 cal Tuesday
-full meal Wednesday morning

I recommend you try a single FD the 2-3 weeks and see how you get on, as it took most of us this amount of time to get used to fasting. After that, when you feel confident, proceed to the double FD.

Most people on FDs do best with protein and veg, avoiding fruit or high carbs. Soups, stews, ready meals are all useful.

Remember to drink lots or water on FDs.

Good luck and let us know how you get on.

Night all.

CuckooAtchooUhOh · 10/11/2013 23:02

Yeah BigChoc - I only use proper butter or various (healthier) oils in all cooking.

I eat chocolate instead of veg.
Biscuits instead of fruit.
Cake instead lean protein.
Sugar instead of sweetner.

Works for me Wink

......um Hmm maybe not???...

CuckooAtchooUhOh · 10/11/2013 23:08

Precisely! Coffee - that is exactly the right attitude to have with this woe. You will find what works for you. It's about experimenting and trying not to be disheartened when things don't go exactly to plan.

This, as you have said, is a LIFESTYLE change. You've got all the time in the world to tweak it. Even on one fast day a week I reckon you could kick half a stone by Christmas! Don't obvs hold me to that, we're all different after all! But given the stories on here I wouldn't be surprised.

Good luck. Loads of us fast tmw. If you feel up for tues too, come end of tmw, I'll keep you company on a back to back. Just got to tell dp I'm not making Thai curry tues after all Grin He can wait til I can have too!!

rubbishfamily333 · 10/11/2013 23:14

Cuckoo - I'm not feeling smug, I am feeling very surprised with myself! Wink

CoffeeOne · 10/11/2013 23:34

Thank you BigChoc

Cuckoo don't enrage DP just yet! Haha. I'll check in tomorrow and let you know how confident I am doing two days, realistically I have absolutely no idea how I'm going to feel! I actually can't remember the last time I felt hungry

CoffeeOne · 10/11/2013 23:37

I'm bookmarked all the links in the first post ready to read through tomorrow for inspiration. Getting a bit lost in all the previous conversation though, would you all mind please sharing what your successes have been with this WOL so far? :)

Twinmama32 · 10/11/2013 23:55

Hi coffee you can do it, this will change your life and its totally doable. In January this year I was 14stone 7. Today I'm 10 stone 13. I have 6Ibs to go before I've lost a total of 4 stone in under a year (started 5:2 on 4 feb this year)
I'm not super fit or active and I'm at home with two toddlers all day but that's the beauty of this woe you can do it whatever your situation.
Good luck! Smile

wildwater · 11/11/2013 05:16

Greetings to all 5:2ers. I haven't posted here for a while...life is getting much busier now that we've started building our house, plus I am working away at painting Patagonian stones which I am selling at the local market (for very little, but it's something!).

For those who don't know/remember me, I began 5:2 nearly a year ago weighing around 83kg. I am now under 60kg (haven't been able to weigh myself for a while) and feel healthier and better than I can remember, thanks to this WOL. I would still like to drop another 7lbs or so, but am happy to let this happen as it may.

At the beginning, fasting was quite hard. Mostly it was just boring - the 'hunger' was never really an issue. In fact I discovered that what I had always thought of as hunger was something different, and nothing to fear.

My partner started fasting wih me after two weeks when he could see the change in me. We have continued together and it is something we both enjoy. We love the simplicity of 5:2. LL says he is never hungry on FDs, which is amazing because he is a hearty eater on NFDs.

We now fast a full 24 hours from the last time we ate, usually around 8.30pm, then have our 500/600 (approx: we don't actually count) meal.

Breakfast the next day as usual, if we have it. I keep toying with giving up breakfast but haven't quite got there yet.

Sometimes I forget to eat enough on NFDs and that doesn't feel good. I cope with FDs much better when I have eaten a balance of veges & protein with some good grains the previous day.

Nibbling is never a good option. Despite knowing what I should and shouldn't do for myself, there are certain foods that cannot survive around me...particularly nuts, and a brand of Argentine chocolate chip cookie. I simply cannot have those in the house or I will eat the lot.

Despite such weaknesses, my new body shape is here to stay. I never want to be fat again. It is quite incredible to fit into things I could only imagine wearing a year ago. Wonderful to sit and move freely. This will be the first summer since I was a teenager (I am now in my 60s) when I will be slim, healthy & well...all at the same time.

I plan to check back here more often.

Cheers to all :)

wrigglebum · 11/11/2013 07:06

Coffee- your ladies for success stories are eatriskier and Bssh- both have lost tons and have before and after pics on their profiles.

My losses are more modest but still life changing. I started in July- I'd already lost half a stone so was around 10st9 (but a bit higher after an all inc holiday). I wanted to drop to 10st if I could. I got there in about a month, added in exercise then stalled for a month. Started losing again and within a month was down to 9st7. That was target (and my lowest weight since age 17) so I went onto maintenance. I've stuck with the exercise and fasting at least once most weeks plus mindful eating. I am now 9st3 and around two sizes smaller.

BiscuitsAreMyDownfall · 11/11/2013 07:25

Thanks all for the encouragement for the half marathon. Registration isn't open yet so there was no chance to register while drunk. IRT running clubs, I am a member of one, but unable to go now due to work Sad

coffee I'm finding it easy to stick to 500 cals one one day, then 800 another day. It's my second week so that's what I'm doing for now.

Good luck for all FDers today

duckyfuzz · 11/11/2013 07:26

Morning ladies, you guys are inspiring, I can't keep up with all the posts though! Toffee I hope dd on the mend now, it's so scary when they're that poorly. Cuckoo hope the hangover has passed! Congrats on all impressive weight losses and discipline over the weekend.

Sat I came in at about 500 over TDEE but Sun was within and today is FD so hopefully back on track. Major period pain since sat lunchtime but have managed to avoid resorting to chocolate. Feel about half a stone heavier though Sad I know it's not real weight! but was looking forward to feeling slimmer! not wobblier!

rubbishfamily333 · 11/11/2013 07:30

All very encouraging weigh losses! Well done ladies I hope I will be able to share some weightloss very soon Grin

Pollydon · 11/11/2013 07:37
postmanpatscat · 11/11/2013 07:43

wildwater nice to hear from you!

Welcome polly you've come to the right place...a way of life, not a diet, is just what you need.

Right, Monday fasters...who's with me? I'm going to be drowning in peppermint tea today and that's it until dinner about 8pm.

eatriskier · 11/11/2013 07:45

coffee hello there. I'm one of those with big losses and photos. Just have a click on my name and you'll be able to see. I lost 5 stone in just over 6m solely doing 5:2. I am a bit of a freak though. Dh is now down 34lb in nearly 3m too so apparently we're both freaks. We both calorie count on nfd. This suits us and helps us make more informed choices. Counting to tdee is far better and more fun than restricting - it becomes more of a game of what can I eat sometimes. Plenty of wine has continued to be imbibed by me Wink although now I'm a lightweight an hideously out of practice Sad

This weekend has been one of lots of calories and shame. Not shame at the calories though. Shame at falling over drunk and ruining a minutes silence by having a coughing fit Blush After working last week I'm looking forward to being a sahm again and returning to normality. And hopefully shaking this fluey thing that's triggering my asthma.

Moving2fast · 11/11/2013 07:46

I've been lurking for a while now but think I need to join this thread. I've been fasting for the past 4 weeks and only lost 2lbs...I even did 4:3 last week but have not lost any extra weight.

I stick to 500 cals on my fasts and am now able to wait until the evening before eating. I think my problem is on non-fast days as I haven't been counting calories and assuming that as I have a lot of weight to lose I will be ok (5ft 3 and nearly 14 stone!).

So as of today, I'm going to fast three times this week and count calories on my non-fast day. I had hope to find a diet where I didn't have to count cals but it seems I may need to do it to see any results.

Have been really inspired by other people's posts so here's hoping I can see some difference in myself shortly.

Pollydon · 11/11/2013 07:58

Ive got cottage cheese (150 cals) for lunch, & a 320 cal ready meal for the evening. Plus loads of water Smile

MelanieCheeks · 11/11/2013 08:04

Just back after an indulgent weekend away, so the scales are up this morning - but I wont let that get to me, I know a lot of it will be water weight. I just note it in the "notes" section of MFP, without actually "recording" a weight.

Not my usual Monday fast either - my sister is over from Australia, and my parents are taking us all out to lunch! But the beauty of this WOE is that I can switch to a Tuesday-Thursday this week.

eatriskier · 11/11/2013 08:52

Just had a sneaky peak on the scales and the damage only appears to be 1lb. Not bad at all, should mostly disappear after today's fast and well within my tolerable bounce maintenance zone.

CuckooAtchooUhOh · 11/11/2013 09:15

Y'know even though I've been lurking for ages and posting for few weeks, I still get the same reaction to the success stories....

WOW!! Twinmama that is fantastic. That is the total amount I needed to shift so always stirs the motivation when I hear of others who have made it to other end of scales.

Just reading all of this mornings posts pretty much sums up the attitude to this woe/wol. How casual and relaxed does everyone sound?? Grin Such a chilled atmosphere among the losers and maintainers (on whole!) Because they/we know that it DOES work, and that it will transform your life, in so many more ways than just losing fat.

HAPPY MONDAY FAST DAY! all partaking!!

And HAPPY MONDAY! everyone else. Was going to say at least it's not 'Shitty Monday' anymore; but looking outside it could well be!

Hi to Pollydon - menu sounds good. Always good to plan in advance.
WildWater Hi (waving)
Moving2fast Hi - def check nfd - loads of peeps on here with advice for mfp and cal counting to tdee.
DuckyFuzz it took just over week from start of totm for me to de bloat and lose excess gained. Pleased to report that despite boozing/bingeing over weekend I have deflated again. So grit your teeth through it!

xCupidStuntx · 11/11/2013 09:21

Good morning everyone!
Today is my first fast day, I just weighed myself and I'm appalled. I've such a big hurdle but I have to take it pound by pound and let the awful number on the scales spur me on!

Black coffee time Brew

CuckooAtchooUhOh · 11/11/2013 09:27

Well Cupid I hope you said goodbye to that number on the scales, because you won't be seeing it for long if you stick to this wol. You've started now! As they say ..Onwards and downwards!! Grin

wrigglebum · 11/11/2013 09:29

FD today. I'll probably have a poached egg and a ton on veg for lunch, then maybe a prawn laksa (with those low cal noodles) for dinner. Plus a square of dark choc after too of course.

Good luck other fasters!

toffeesponge · 11/11/2013 09:30

Welcome Polly and CoffeeOne.

Thanks for all the good wishes. DD in bed. Temp up a bit. Has managed to eat some rice crispies. DS2 now complaining of neck ache and has coughed a couple of times Sad. I also have a headache coming.

FD today and I want to comfort eat but of course, food is not a crutch anymore..

CuckooAtchooUhOh · 11/11/2013 09:37

NSV - Knickers are too big. Knickers are too big. Knickers are too big. Knickers are too big Grin Grin

Just as well in this weather; can pull them up further for extra warmth. Not long until I can tuck my boobs in!

Eat never get tired of hearing your story!
