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 or app 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 TDEE calculator to help you figure out how many calories you should be eating in a day.

NFD = Non fast day

NSV/LSV = Non scale victory/Lifestyle (change) victory

Exercise: bigchocfrenzy has an incredibly informative and helpful exercise and fitness thread for discussion and advice on combining 5:2 with an exercise regime.

Maintaining: 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.

Other links
This is a BBC article regarding Michael Mosley's findings, which was featured on Horizon - link to that programme here.

This Telegraph article comments on the diet and gives a brief overview by Dr Mosley himself, very informative if you're just starting.

This blog post 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 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 article 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. (Though anecdotal evidence from these long-running threads may suggest otherwise…)

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 way of life!

mazzle A lot of us found that our weight would bounce around a number (ie up and down), then suddenly drop 2 or 3 pounds, then bounce again and so on. It seems disheartening as the loss isn't consistent, but the overall trend is still down, despite the bounces up.

Go and look on Bigchoc's exercise thread - she set me some xfit pressups which I can do! And make me feel like that I will, one day in the not too distant future, be able to do real ones, properly. It's a revelation.

Does it really matter if I go over 500 cals? If, say, I do 3x700 cals in a week instead of 2x500 cals, wouldn t that work just as well as the weekly total cal intake would still be less than the recommended for an adult woman?

TheBitchesOfWeestick · 10/01/2014 08:23

Just quickly logging last night's food before I do the school run: had chicken curry (Hairy Dieters jalfrezi, a favourite recipe in this house), fried new potatoes, mango chutney, yoghurt, two beers AND a glass of wine with our neighbour...and would still have stayed in calorie limit for the day, had it not been for the roti I added to the meal! Very instructive. I didn't even want the roti that much, esp not with potatoes as well, so will learn for next time.

Also had a minor NSV, in that I tipsily considered having some chocolate, then thought 'do I really want it, given that it will almost certainly push me over my TDEE if I'm not over it already?' Decided I didn't, and also decided against a second glass of wine :)

I'll try and catch up with this sprinting thread later Grin Will check out the exercise thread too.

ErrolTheDragon · 10/01/2014 08:23

Also, my FD are on different days every week, so if I was to try and weigh myself weekly, I wouldn't know which day to do it.

How about you try to weigh on whichever FD is, or is the next one after ,a particular day of the week - so its approx. weekly but under consistent conditions. I try to always weigh on a FD after one drink and the loo - inputs/outputs can make a significant difference!

zedzedzed · 10/01/2014 08:27

mazzledazzle

I'd bin the scales and just measure yourself or weigh in ONCE a month so you can see the trend is generally down. Maybe keep the scales at a friend's house out of temptation. Sounds like you're doing brilliantly.

PS I had an implant after my 1st baby, it didn't suit me at all, lots of weight gain (another reason I'm here) and loads of feeling pregnant all year round (insanely moody/bloated/starving). Felt SO much better once it was out (lost weight naturally, moods stabilised etc) but then I decided to have another baby so all bets were off. Just a thought, if you're finding it tough perhaps there's a better form of contraception for your body?

Happy fast day to you!

VERY happy NON fast day to the rest...lucky buggers.

lucyintheskywithdinos · 10/01/2014 08:45

This morning I am hauling myself up and giving myself a kick up the bum. I am putting in place a 'fuck off plateau' plan.

I'm struggling with my body image a bit, have convinced myself that I am gigantic, which is utter nonsense, I'm only a few lbs from 'perfectly fine' and a stone from 'ideal'.

And I have a date tomorrow!

Anyway. Off to do press ups until I can no longer press up!

ImABadGirl · 10/01/2014 08:47

zed I'm doing the 30 day squat challenge, I'm on 65 squats today so will get them done.

Meant to be a FD but am giving blood later so better I have a NFD today and fast tomorrow, having tea and toast in a minute Smile

Happy fasting today peeps

zedzedzed · 10/01/2014 08:47

Oh no. Just read the exercise thread...that earslaps lady is going to come and get me, quick start a new thread for hiding in! Fecking planks...I wept self-pityingly for an hour when I tried the planking bit in some post-pregnancy American chick's dvd; couldn't believe my muscles were paralysed (who else said that? Too true) completely severed.

It did get better, but not with that postnatal abs and planking cow, time and do-able strength training helped a bit...but then I had an even BIGGER c-section (my last baby was 11lbs12. That is not a misprint, 11lbs12. And no I don't have Gestational Diabetes and she's not a fattie...but she is about 6ft long!)

mazzle yes...but it's called 'shred'...and 30 days on the trot? I need one called 'today and never again, except in a couple of days, if you can face it again, sorry love'

BetsyBell · 10/01/2014 08:48

Frozen try doing normal 5:2 but aiming for (say) 750, then gradually reduce it over time. That might feel more doable.

New starters - if you go over 500/600 - you haven't failed! Just try and get close to the mark next time - it doesn't matter how long it takes.

OP posts:
BsshBossh · 10/01/2014 08:49

Mazzle if I were you I'd record my official weight on the morning after my 2nd FD of the week, whichever day that fell.

Bitches terrific NSV!

BetsyBell · 10/01/2014 08:50

Zed How about some nice walks instead! Or a bit of Just Dance. It's all good, just get moving. Jillian is evil (though I do love her), but for now focus on upping the moving about. x

OP posts:
zedzedzed · 10/01/2014 08:50

Any links to this squatting challenge? can't see it, sorry. Thanks.

ImABadGirl · 10/01/2014 08:54

30 day squat challenge....

Day 1 50 squats
Day 2 55 squats
Day 3 60 squats
Day 4 Rest
Day 5 65 squats

and so on and so forth until you get to a massive 250 squats, make sure you rest every 3 days Grin

zedzedzed · 10/01/2014 08:56

Ok...looks pretty straight forward...damn it. I better shut up and go squat then. Not a sentence I had planned for this morning.

Cheers all.

Itsaboatjack · 10/01/2014 09:02

Frozen I agree with BetsyBell, if you think you can't go to 500 cals yet then work your way down to it at your own speed.

Mazzle ditch the everyday weighing, try and stick to weekly, or even monthly if you can't wait that long. Do it under the same circumstances, ie first thing in the morning after df, or whatever works for you.

Zed I think it's very sensible to focus on one thing at once. When you got to grips with this woe and started to see so e results you'll probably find you want to start exercising as you feel more confident and energised.

I forget who it was a few pages back who mentioned stretchy jeans. I totally agree, it's so easy to put on a few lbs and then a few more without noticing as so many of our clothes stretch so much. When I get to goal weight I'm going to buy a really good pair of jeans with no stretch and make sure they stay comfortable.

Have a good day everyone.

AngieM2 · 10/01/2014 09:03

Friday weigh in (after 2nd FD) 2lb gone. I'll take that thanks you. Just off to spin, not eating til lunchtime. 3NFD's. Love this WOE

MrsFlorrick · 10/01/2014 09:07

Argh. We have the D&V bug in the house. DD started vomiting at 3am and it took several hours for her to stop. Yikes. Just waiting for me and DS to start. Weeps.

So much for my dinner party tomorrow. Angry

Amazingly. I dealt with the first two vomit episodes and DH actually got up and dealt with DD after that so I could go back to sleep. Wonders will never cease. Was taken aback.

CuckooAtchooUhOh · 10/01/2014 09:17

MazzleDazzle you said it yourself.. I know I shouldn't weigh myself everyday.....and this is why!

Weigh in no sooner than once a week. Make your weigh day the morning after your 2nd (last) fast day of week.

If you sneak a peek early - it doesn't count! Only the official weekly one does.

This way if nothing else. You only get to feel crap about the numbers one day a week!

Works for me. Post poo, before eating/drinking morning after 2nd fd.

Whatever you do be consistent. But not daily! Grin

RavenousRunner · 10/01/2014 09:23

mazzledazzle what sort of implant do you have? I have an IUS/Mirena, and after getting it put it I gained about a stone in a few months, and felt all bloated and horrible. After that it settled down and now I wouldn't it give it up for anything - no periods has been a huge revelation! I still have cycles, but much fewer side effects than before. Apart from getting spots on my chin EVERY BLOODY MONTH which apparently is a curse I will never be rid of.

Even after slight dinner failure last night, down a pound this morning, and my suit trousers are fitting the way they should again. Unlike my traitorous stretchy jeans my work wardrobe lets me know the second I've eaten too much - I had everything old tailored when I started having to wear it every day, so it is all exactly fitted to me at 10 stone 5 lbs. Good way to be forced to keep an eye on things. I suppose in the olden days when people only had a limited wardrobe and none of it stretched putting on weight was a very expensive proposition!

Woke up starving and had two wholegrain rice cakes with peanut butter and banana before my run - they may have been the most delicious thing I've ever tasted.

CuckooAtchooUhOh · 10/01/2014 09:27

Ended up eating last night after all, reckon was under 650 so calling it a fd. Just waiting to move before first drumroll official weigh in since Christmas.

Can see the difference already though. My face has lost a lot it's puff.

I am starting to realise just how much of my expansion after blow outs is because I am still actually holding what I've eaten! Which is prob exactly why this makes such a huge diff because you have to pause the gobbling twice a week which allows a catch up plus reduces total weekly input too!

Chrimbo created quite a backup! Disgusting to think really that I was just cramming more and more on top. Just because you wake up and it's a new day, does not automatically mean you have to starting shovelling food in again.

It really is about rediscovering and connecting with genuine hunger!

Stating the obvious post ALERT!

ErrolTheDragon · 10/01/2014 09:52

On the consistency thing when weighing - a mug full of water weighs 10oz. If you usually weigh before consuming anything, and then next week forget and have a cuppa first, don't be surprised if you're half a pound more than you were hoping!

Weighings at a GPs visit, or in an evening are going to be very variable unless viewed over months rather than weeks.

BsshBossh · 10/01/2014 09:58

AngieM2 great weightloss, well done! You too RavenousRunner :)
MrsF oh no! Hope the D&V sweeps quickly through.

NFD today: panettone buttered toast with Red Leicester for breakfast, along with a mug of hot milk. Am very satisfied now and ready to work. Might have sushi for lunch and then we'll be having cheese omelettes with chips and cherry tomatoes for dinner tonight followed by a slice each of tarte citron. I love the no-guilt eating of 5:2.

Jobyloo · 10/01/2014 10:20

Morning everyone! Am jumping aboard with you all. Tried this 5:2 very half heatedly last year and don't want another year to go by feeling v unhappy with my weight & shape.

The inspirational thread is amazing and yep v inspirational for this newbie. 3rd FD yesterday and really pleased because I'm down 5.75lbs since NYD. Am going to have a look at the exercise thread, must be mad but I'm loving the sound of the squat challenge Smile.

Looking forward to getting to know you, from what I've read so far you seem like a really friendly bunch Thanks

Eatriskier · 10/01/2014 10:26

mrsf you guys don't have much luck with these bugs do you? Hope it doesn't linger for you all

toffee if you aren't ahem eliminating properly you may find both the scales and measurements creeping up. The both will drop once you go fully.

Have done a 0.7mile jog already. Not sure why Dd feels the need to motivate me to exercise given she is only 3 but I'm guessing it's something to do with bcf Wink Grin

WhenSheWasBadSheWasExhausted · 10/01/2014 10:35

I know someone who went on the implant and put on about 2 stone (she's only 5 foot 1. I think weight gain is quite common.

imabadgirl I've been doing a bit of a squat challenge, it's hard to find time for proper excercise but even I cm can find time for these. I'm up to 105 squats. Taking a break this week as I'm a bit poorly.

zed try squats they don't take much time and you feel like you've achieved something (just watch your knees)
