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

BetsyBell · 23/06/2013 15:54

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!

saf and betsy your news both sucks and blows, hope tomorrow brings more improvements in terms of clearer news for saf and happy dc for betsy, big hugs and a good nights sleep all round...

michelle you get to choose whichever fd's you want, people don't tend to do 2 in a row regularly as it's hard going! If you're happy, go for it :)

Had a good fd here yesterday (I'm another Tuesday/Thursday girl) and not a bad day today - enough cals for big bowl of spag bol, glass of wine and pudding biscuit for dinner. I've also done 6 hours of wallpaper stripping, so surely that's equivalent to some torturous exercise dvd?!

Have also planned fd tomorrow, already have M&S prawn cocktail salad in fridge at work with 1/2 another bag of salad as the box is a bit stingy. Will be doing lunch time circuit training, so feeling good about it already.

I also want to whisper quietly (as I can't quite believe it) that I'm now 10 st 10 Grin not seen for 4 plus years, and DH says he can see the difference. Brilliant motivation to keep going and not sabotage by stuffing my face with junk!

EagleRiderDirk · 26/06/2013 22:45

first day since Saturday that I've had breakfast. three medals a day rocks! Grin

EagleRiderDirk · 26/06/2013 22:46

*meals. stupid phone

MichelleRouxJnr · 26/06/2013 23:26

Thanks.
Might stick with the Mon/Tues thing then.

Will definitely keep reading (and posting on) this thread - s'great!

Well done alwaysanauntie - seeing and feeling the difference makes it so much easier to stick at it.

Last thursday I was struggling a bit during the day with the old rumbles, then a colleague commented on my weight loss and I sailed through 'til teatime Smile (10st 11 to 10st 4 here so far - if I get below 10st will be the first time in many years)

Tortoiseonthehalfshell · 27/06/2013 01:10

Oh, Betsy, what an awful day you've had. For some reason those sorts of things always seem to happen when the other half is away. I hope you're all sleeping peacefully now and feel much better in the morning.

Somewhere I am always ravenous in the early months of breastfeeding: I know there are several of us who do 5:2 with little ones, but I can't imagine it. I eat for my country until the six month mark (and I'm lucky, I lose weight during that period anyway). So I'm not surprised that you find it tough too. I bet the weight comes off for you - if you're feeling a lot of hunger, that usually means you're burning energy, right?

AS of this morning, I have managed my first proper 5:2 week for three weeks, after two weeks in a row of 6:1 (with mini-fasts squeezed in around insane work commitments). And this morning, I was 3lb down, so I'm finally back to 60kg. I expect to bounce back up a bit again, but hopefully this time I won't go back to 61.5 and stall there for so long. It's all the more surprising because AF made a surprise visit, and usually she brings a few pounds to cover her stay.

ceebeegeebies · 27/06/2013 06:15

Morning all. No need to get up early this morning as notworking today but my body decided to wake up at half 5 anyway Angry

I have a bit of a dilemma and would love your thoughts. Due to DH's work and other commitments this week, I can only fit in a gym session on Friday evening. However that is also the only day I can fit in my second fast of the week. The gym class I want to do is BodyPump (weight training) and I still do not feel able to exercise on a FD, , particularly not lifting heavy weights. So my question is do I do 6:1 this week and fit in my gym class or do I do 5:2 and miss the gym...which would be more beneficial? Or could I do 16:8 and just eat normally from lunchtime on friday??

BsshBossh · 27/06/2013 07:36

ceebee you'll have a greater calorie deficit for the day if you fast rather than go to the gym. If it were me, I'd choose fasting over gym.

FD for me today. Who's in?

mttum · 27/06/2013 07:38

Morning everyone, and I hope in particular that today is a better day for saf and Betsy FlowersFlowers

I've been absent from the thread for a few weeks now, but plodding on with the WOE. Just getting mildly discouraged, and wondering if anyone has some advice or insights.

I started off doing 4:3, zero cals on fast days, about mid April. Switched to 5:2 a couple of weeks ago, again zero cals on fast days. Weight loss has been ok, but not superfast, about 14lb in 10 weeks. My problem is that I have hardly lost anything from my waist, which is what I really need to do for health reasons. It's gone from 42 to between 40.5 and 41 inches. At my height I should be aiming for 36.

I don't calory count on NFDs, although I did to start out with, so have a reasonable idea of what is my TDEE. As a 6'1" man I'm not too unhappy with my current 14st, but would love to get those inches off! And yes I do exercise, 4 or 5 times a week, including abs.

Sorry for writing a book - making up for lost time! Best wishes to all fasters today - I am too Smile. You are all such an inspiration to me Thanks

mttum · 27/06/2013 07:52

ceebees, have you actually tried doing weights on a fast day, or is it that you don't like the idea of it? I have found that, if anything, it's easier for me to exercise on fast days (mainly body weight resistance training), but I guess it's different for everyone. Maybe try combining a fast day with a long brisk walk, especially if its a nice evening Smile

eastlondonlite · 27/06/2013 08:26

Morning! ceebees I've found exercise ok on fast days once I got over the fear of passing out on a treadmill - find it distracts me from wanting to eat.

So I've had a completely disappointing morning. I've just woken up from my seventh fast keeping to exactly 500 cals and fasting for over 22 hours and I woke up 2.4 lbs HEAVIER than last weigh in on Sunday morning I'm utterly confused!

It's the first day of my period.. That's the only explanation I can think of. Help!

swallowedAfly · 27/06/2013 08:31

morning all Smile thanks for all the un'mn'ness Wink

weight about the same this morning so that's good. also noticing with my body now that actually it's relatively slim - if i could literally just tuck that messy bit of mummy tummy in a concealed pocket i'd be happy. i still have a fair way to go really but i'm stopping to notice where i'm at itms.

my referral has gone over to the right person so i'm just waiting to hear of an appointment now - doubt i'll get one before my holiday - i asked my surgeon to pass on my holiday dates and it seems unlikely they'll fit me in before. going to try not to worry and keep it in context and focus on best case scenarios rather than the worst ones i was wallowing in there briefly.

hope you dc is ok betsy - scary stuff. it's the adrenaline afterwards i think that shakes you

Crunchymunchyhoneycakes · 27/06/2013 08:36

Hello all, just popping past to say hey, I have decided to try 16:8 on 2 (maybe all? Too much?) of my non fast days but I have to say that without counting I think yesterday was a bit of a washout!

That'll be the (look away now if its a fasting day!!) oreo cheesecake cookies I made and then ate Blush 4 (maybe 5) of.... Also just generally crap eating all day albeit in an 8 hour window... Anyway - today is another day need a new attitude to treats - just have 1 then I can enjoy a treat and not feel crap about it.

I last weighed myself Tuesday after my last fast day, may check again today and see what the damage is! Went away and then added - Just did this and am officially (e.g. Not after a fast day - under 10 stone - JUST) - hooray!

Been looking on Pinterest for 5:2 recipes and noticed people are tagging with 5:2 on Instagram too...

Have a lovely day all.

ceebeegeebies · 27/06/2013 08:37

Thanks for the advice. I think if the class was cardio-based I would probably risk it but as it is hard core weight training, I am really not confident enough to be lifting 20kg above my head repeatedly on very little food Wink. Might do the long walk instead Smile

Bssh yes, I guess it is the calorie deficit that I need so maybe a FD and a walk should do it Smile

swallowedAfly · 27/06/2013 08:41

crunchie it tends to work out that i only eat in a 5 or 6 hour window most days. if i eat over more time than that i tend to feel really sluggish and bloated and bleurgh and generally i just do not feel the need to eat in the day. this woe gave me permission to go with that and shrug off the lectures i've had about it all my life. if you're just going for two of your non fast days like that maybe consider a shorter window for best benefits - like 4 or 5 hrs.

BetsyBell · 27/06/2013 08:47

Thank you thank you all for the well wishing and hugs yesterday and apologies for hijacking the thread slightly off topic. Lots of lovely sleep and we all feel a little better.

After my carb loading yesterday I am fasting today - or at least until this evening where weather dependent we'll be having a takeaway or meal out :)

Busy morning but will catch up with the thread later x

Cluckingmad · 27/06/2013 08:59

Today is my second fast day. Been for a little run this morning which has left me feeling strangely energetic. I am off out for a coffee with sis in law today, planning on black coffee just hope I can resist the large latte and carrot cake Hmm Hmm

somewherebecomingrain · 27/06/2013 09:06

betsy glad you are better today. My ds is in a&e too often with cuts I know how it feels!

saf glad you feeling more positive. There are such a spectrum of cancer situations and yours is at the curable end. I went through similar thinking I've got the gene I've got the gene oh no then realised I can be vigilant and catch it early and I'm lucky.

cbeeb yes do a fast and different excersis that is compatible with fasting. I find excersis easier on fasting days - think its the fat burning thing - so take advantage.

tortoise after my first baby my metabolism was all screwed up. I breastfed but lost no weight - was 13 stone, clinically obese. This time although I dipped to 12 after the birth the scales were creeping up. So not enough just to breastfed for me. Think 16:8 might be enough for me. Did it yesterday and survived on prob around 1800 cals which is a deficit. Gravitated towards healthy food and felt no hunger except 10-11am. By the time it was time to eat I'd forgotten I was hungry.

Thanks for your support though tortoise and also elr

saf agree its permission. I've always wanted to go back to how I ate at college - between 11am and 4.30pm - but never felt I could justify it. Now I can.

Xx

BsshBossh · 27/06/2013 09:25

saf if they thought your situation was very serious they'll have rushed through your appointment asap. I had cancer (not breast) a decade ago - they rushed me in so quickly I didn't have a chance to take a breath. It was quite serious. Luckily all well now. I know it's so, so difficult, but try and keep calm. I remember reading loads about my illness really helped me stay rational and realistic.

Dotty342kids · 27/06/2013 09:28

BssBossh I'm fasting today too. Did a kind of mini fast yesterday - didn't eat till 6pm but then prob had around 800-1000 cals.
Today is proper fast Smile.

Hope everyone fasting today has a good day!

BsshBossh · 27/06/2013 09:38

eastlondonlite of course it's TOM. I always gain or stall then. It's TOM week for me too and I'm debating whether to weigh in tomorrow or not.

crunchy well done on the loss, hurrah! I try and do 16:8 on 3 NFDs but I minimise treats on weekdays to one small pudding after the evening meal (no snacking in between meals). I eat slightly larger main meals to compensate though and make sure there's enough protein in each to make me feel full enough to not snack in between. I don't count calories but I figure I'm within TDEE.

ceebee I lift that heavy on FDs for 45 mins but only because I am able to do so without any ill effects. You know your body better than anyone so a long walk might be better.

alwaysanauntie · 27/06/2013 09:39

Note to self, do NOT drink wine the night before a fast day (only 1 glass, but feel huuuuungry this morning :( )

Talkinpeace · 27/06/2013 10:16

ceebee I've done pump a few times on fast days : its quite a buzz.

mttmum DH and the DHs of various friends are doing 5:2 - silly thing. .... Are you keeping your fluids up on your fast days. Allowing yourself 100 for milk in tea and then a 500 calorie supper : lots of veg and eggs might tip your system into a change mode.
The other thing that several of the men have found - cyclistist in particular - is that exercise on fast days has rather splendid effects.

eastlondonlite · 27/06/2013 10:41

Thanks BsshBossh TOM also making me a bit irrational about it all too probably! Off to Wimbledon on a fast day tomorrow so that's going to be a challenge. I wonder what the rules are on making up your 500 entirely in Pimms...

crunchy does 16:8 on non fast days mean that you do a sort of mini fast and then eat between lunch and early evening for 8 hours?

dines · 27/06/2013 11:11

Fd for me today had a good one on tuesday hopfully another good one today. Gonna have another soup 200 cals. Iv had two teas and one coffee today with two sugars. Iv got a party next weekend and hove brought I figure hugging dress its comin tomorro so I hope it looks ok. Who else is fasting today and wot are they having?

BsshBossh · 27/06/2013 11:16

dines I'm fasting today. Black coffee, water, herb tea all day then vegetable curry and a bit of rice for dinner tonight. It's my TOM, though, and I'm finding fasting today quite tough... made even more difficult because I am housebound awaiting a kitchen delivery. Argh!
