The 5:2 Thread number 22! Put down that biscuit - you can eat it tomorrow

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 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 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 Greeneggsandnichts for putting together all the 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!

OK, I guess it whatever works for you kind of thing. Smile TIP I totally get how logging exercise and eating calories back would make it an excuse to over eat.

post you will be absolutely fine without logging your food. If your weight creep backs up over a few weeks or your clothes start getting a bit tight (however you measure), then you can think about maybe logging again for a bit. However, I doubt that you will have to because you seem to have sussed out what works for you. Smile

JB30 · 30/06/2013 14:29

Nelly I'm tacking my insomnia at the moment too. Read a kindle book by a lady called sasha stephens, pure sense and it's working. Sleep hygiene is v important, o beds for sleeping, nothing else (Except, well you know Wink) go to bed only when tired, get up when you wake, no afternoon naps etc. Worth the 4 quid, on day 3 of decent 7 hour sleep AND used my early wakes to do ironing, everyone's a winner.
Just broke my 16:8, ahhh, lovely

MissUnicorn · 30/06/2013 14:59

Afternoon all. Am about to break my fast after I do my callanetics session.

What do you do when you are simply not hungry but have loads of tdee calories to use up?

Talkinpeace · 30/06/2013 15:00

enjoy the weight loss

akarucker · 30/06/2013 16:16

missU that is an alien concept to me, and I am very Envy

ceebeegeebies · 30/06/2013 17:50

Missunicorn - that has never happened to me so I have no idea Grin

Dotty342kids · 30/06/2013 18:44

Peplum, yes, first year in tent on his own but he's been camping with us / cubs for several years now so is pretty confident. He has dog in with him for extra security / my peace of mind! He doesn't have a pop up tent but it's dead easy to get up within ten minutes (he does it).
This morning we got up in a leisurely fashion, had breakfast, emptied out inside of tent, flew kite whilst waiting for morning dew to dry off, packed up and were back home by 12.00! Perfect Smile

Dotty342kids · 30/06/2013 18:56

Headintheclouds whoop to you! Losing a stone to get to first target is fab, well done! What's your new target going to be then? Smile

I'm back from a weekend of camping on a farm that makes its own ice cream. Fatal. Plus typical camping food / drink. Enough said Wink
Got an uber stressful work meeting in London tomorrow so will be on trains for hours. Can't decide whether to fast or not. Figure that the stress and worry of it might knock my appetite anyway and then all the unpleasantness of it / fast day will be done and dusted in one go....

akarucker · 30/06/2013 19:09

Dotty go for it! You'll feel extra powerful if you're fasting anyway. Get all your triumphs done in one day!

somewherebecomingrain · 30/06/2013 19:33

Oh gaaaad I'm gonna fast tomorrow after a week off, doing only a couple of 16:8s. I hope it will be easier. Planning 3 eggs with a little grated cheese for lunch and an early dinner of a ready meal, or soup and bread ( I give myself 650 cals as a breast feeder). It's so hard but after a week off I miss the energy and lightness I felt -hard to explain.

Will be on here for moral support!

ceebeegeebies · 30/06/2013 19:44

somewhere - I am with you although I am not fasting until Tues. I really need to refocus as I have slipped off the wagon in terms of overeating in NFDs and probably eating 700 cals on FD. Haven't been to the gym as much as I would like either Hmm

So from tomorrow, I am going to aim to stick to 2000 cals in NFDs and try and get to the gym a bit mire often.Holiday is in 8 weeks...

MissUnicorn · 30/06/2013 20:25

LOL [Tip Akah & Ceebee] it's probably cause you have loads to do. I have mobility problems and use a walking stick, so I guess I don't get as hungry.

Like today, I had fresh fruit with yoghurt Brazil nuts and cashew nuts at about half 3. I would've been happy to just eat that, but have eaten more because I don't want to get into starvation mode. Confused

Go for it [Dotty]. If you bring something with you, it'll be cheaper as well.
I'm fasting as well tomorrow [Somewhere] so will see you here!
I'm going to have a prawn stirfry, no noodles or rice. I seem to naturally do no/low carb on fast days.

amigababy · 30/06/2013 20:38

ceebeegeebies ditto exactly - holiday too - feeling a bit fat today and need to do something constructive

Itsaboatjack · 30/06/2013 21:27

Just got home from a lovely weekend at my parents where I enjoyed a lot of my mums amazing home cooking and baking. And being a typical Brit who hasn't seen the sun in goodness knows how long; I am very sunburnt.

Should be an FD tomorrow but I have a long meeting with my boss that I'm pretty sure is going to turn into a working lunch, so if it does then I think I'll push it until Tuesday.

It's just over 3 weeks now until my hols, so I am planning 3 weeks of extra effort to try and lose as much as possible, and tone up as much as possible before the bikini comes out.

SoTiredAgain · 30/06/2013 22:02

JB30 thanks for the tip about sasha stephen's book. DP suffers from insomnia and feels desperate about it so I have ordered it for him.

headintheclouds · 30/06/2013 22:45

Hey dotty glad you had a good weekend camping. Id definately go for the fast tomorrow and get it over & done with!
Since you ask, my next goal is to get to 9 st 7 lb.... another 9 lbs ...Ive just been looking back over my stats on MFP and it took me 12 weeks to lose the first 9lbs. Going on my hols in 6 weeks time so if I can be in the 9s by then that will be good.
The 3 lb loss I had this week has got to be a fluke and in my experience the next 3 -4 weeks may now be slow..its just my rhythm I think, also TOM due any day so Ill be retaining fluid this week!
But am going to carry on with 16:8 on NFDs plus more exercise because it seems to have worked... Good luck to all fasters & non fasters tomorrow.

Tortoiseonthehalfshell · 01/07/2013 01:21

Hey, all. Monday morning here, and I'm up 3lbs from Thursday. Yesterday was a total wine and cheese fest, though, so I'm hoping it'll shift itself. Otherwise I'm doomed to lose the same 3lb over and over forever.

I think I'm going to have to go and start taking MFP seriously after all. My fitbit has a calorie-tracking system as well, but MFP is better in this regard - and I think TIP is right about just eating the same cals every day irrespective of exercise.

Good luck somewhere!

peplum41 · 01/07/2013 01:59

Hi all, at work hence the weird time. Decided to forego usual midnight snack to see if I can manage a night shift on my fat reserves. At the beginning of a fast, I always feel a bit reluctant, and there's a small voice saying eat those crisps and that banana. Later, tummy, later.

Hi to all the new 5:2ers that have joined us over the weekend. Glad you sorted out your TDEE, captain. I'm not sure that eating up to it will actually help you lose weight faster, but I'm sure it will help you stick to the two fast days, which is better in the long run. Makes the whole thing more enjoyable.

tortoise are you doing loads of exercise, just out of interest?

ceebeegeebies not been able to get back to the gym myself. That's one reason why I'm using the free ones until I can sort my routine out. I did manage an exercise dvd on Thursday.

molly and missunicorn starting this way of life is a great distraction for the sad and stressful things life throws your way.

dotty, glad you liked your weekend, should've set you up for your fast and much dreaded meeting. Thanks for tips. Bought some dinky non-stick pans to add to our little camping collection.

peplum41 · 01/07/2013 02:09

I put Molly but I should've put nellymay. Moving house and losing a loved pet, v stressful. No harm in trying to start, but we all agree the first few fasts are the hardest, they get easier. I realised last week, I need to not drink the night before. News which my liver will be pleased with, as it now gets the 2 fast days, the nights before and the 2 nights when I'm at work to not have to process alcohol.

Tortoiseonthehalfshell · 01/07/2013 03:11

Peplum no - I try and hit 10,000 steps a day, and do the occasional jog (but its midwinter here, so that's tricky because I don't have enough daylight hours and there's no street lighting or pavements along my way), and I do a fencing class once a week, that's it. I have bought exercise DVDs before and never even looked at them!

CrystalDeCanter · 01/07/2013 05:22

Hi all, I've been off mnet for the last couple of weeks, but I'm back now! Fasting today, flipping starving, but I know it will pass.

Well done all those who are dropping the kilos and hi to the new people. I won't lie to you fast days are tough, but it's only 24 hrs at a time and the benefits are great.

I haven't weighed myself for a few days and have been mildly ill so not as much exercise although I took the kids on a 7k walk yesterday. Peplum I agree that no alcohol before a fast is a good idea. Anyone here intending to do Dry July? In fact is that a thing in the UK? It's quite big here in Oz, you give up booze for July. I'm debating whether to do it or not!

peplum41 · 01/07/2013 05:57

Hi crystal, had noticed your absence! Hope you're feeling better soon. If we do have dry July, I've not heard of it. I think a lot here do dry January, to ward off the excesses of Xmas and new year. I've heard that if you can't do a month alcohol free you may have a drink problem! Never managed it so far. It's the socializing, not the sitting at home drink I crave.

tortoise, are you managing 10000 steps quite easily? I think I manage that with the dog. I'm lightly active on my TDEE.

babysaurus · 01/07/2013 06:15

Hello...?
Newbie here. This is my first day and I'll be in here a lot for motivation. About a month back me and DH did a week (ie two days) but have since got distracted but am now back on the straight and narrow as something has to be done!
I don't weigh myself but am currently about a 16/18 and am guessing I weigh about 13 stone (am five foot five.) My legs aren't too bad but my middle, arms and face are awful - I never wear short sleeves and my face is getting far too round for my liking.
My DS is 13 months (today!) and is currently waking up at 4.30 most mornings so I already feel like making lattes and stuffing myself with croissants. Not that I will, obviously, but it feels like a long day already! DH is working away this week too so am on my own - he's doing it too but its far easier when he's actually here.
So ladies, wish me luck!
Will browse through the thread properly over the course of the day...

Tortoiseonthehalfshell · 01/07/2013 06:57

Good luck baby!

Peplum - no, I really have to try to do it, so it's definitely a shift from my pre-dieting self. I have a very sedentary job, and a long commute (1 hr+) so it's really hard to find any time to get outdoors and go for a walk. I do manage it on weekends and I get close on my days at home with the DDs if the weather's fine enough to drag them around the duckpond and chase them across a park, but it's a real struggle. I count myself as "lightly active" as well, in part because on my days at home I do a lot of lifting and bending...usually trying to stop an eighteen month old from damaging things!

postmanpatscat · 01/07/2013 06:59

Morning all

Welcome and good luck babysaurus

Good luck to the rest of today's tasters.
