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!

Thanks dotty, i thought that was right! soup smells great, looks very filling too. Looking forward to being out of the house so it can't torment me any more!

Dotty342kids · 24/06/2013 11:21

Just keep busy crunchy, busy, busy, busy Smile

newbiefrugalgal · 24/06/2013 11:22

Weigh in day for me - scales are down 2.2kg to 68.5kg.
Started being strict on 10th May (after consuming a whole block of dairy milk the night before and waking up feeling 'yuck' AGAIN!
(previous half hearted attempts earlier in the year too)

I'm aiming for below 60kg as this is what I have been pre and post babies but more importantly I just want to wear all my summer clothes!!

I'm sick at the moment so didn't get my second fast day in last week, I have however eaten only healthy snacks and mostly sensible meals. Still unwell today but hoping to get through the fast day as getting it done on Monday much such a physchological (SP??) difference.

BetsyBell · 24/06/2013 11:28

FF Ooh, thanks - I've popped in my recipes bookmark, it'll be saved for a bit of weekend baking at some point!

Likehurricane aw, thank you :) x I usually look forward to Monday's fast after a weekend of tastiness. Thursday's are usually the hardest one, especially if I've been eating mindfully on Tues/Weds - as Dotty says, that's the weight loss one if I'm lucky.

Stomach is rumbling so it must be time for a drink! Not long for me to wait to have my salady lunch as I eat early on Sunday :)

Have been without my laptop for a couple of weeks so have had to do a major catch up.

Waves to Peplum

20 weeks in and 21 lbs lost which included a 5 week plateau

I have just booked 5 nights at a hotel and with my new 5:2 mind set I have not booked breakfasts ( the eat all you want type ). I always used to eat loads and still have lunch now I know I will be fine 'til lunchtime

Saves me £40 and will give me an extra couple of hours a day to do interesting things in London

Hope everyone is getting on ok today

Tortoiseonthehalfshell · 24/06/2013 12:38

I think Monday is a pretty universal fasting day, so to all. End of the day here; am at 350 or so, considering whether to get up and make a snack, or just go to bed.

Somewhere am I right in remembering that your baby is very young still? I bet you'll find that you lose weight anyway over the next few months...maybe keep 5:2 in mind for when the weight loss stalls. We'll still be here!

TweenageAngst · 24/06/2013 12:48

I have lost 11kg since mid March doing 4:3. Have now dropped to 5:2 for the remaining 5 kg I want to shift. I have found it pretty easy and I am lighter than I have been for over 10 years. I just have to make sure I get the arse/face balance right. Grin

Meggymoodle · 24/06/2013 13:03

Hello again. V excited to see 10st 7.8 on the scales today. First time in nearly 5 years!! Had a gain last week which someone on here suggested was due to TOTM which I think it must have been.

Tragically though -much of this stone I have shifted has gone off my boobs - which I couldn't really afford to lose. I still have my belly though - any suggestions?

EagleRiderDirk · 24/06/2013 13:24

meggy congrats and commiserations maybe! A few of us have done the 30 day squat challenge, I'm convinced that's helped me lose inches off my stomach (as well as weight loss obviously!)

vieenrose · 24/06/2013 13:36

meggy

I've found that 10 mns abs a day have really worked for me. I've lost over 25 cm from my waist and 15 cm from my belly. Ten minutes is not too strenuous but I do do it every day. My problem now is that the skin on my stomach is slack...But you can't have it both ways...
Hello to fellow Monday fasters

JB30 · 24/06/2013 14:05

That's a brilliant idea about the breakfast mehefin I'm going to use it on my next business trip. Delighted is morning as 2nd Monday with weekend bloat only showing as .4 of a pound. Ok FD so far, just ate lunch and feel the hunger monster growling but will get stuck into some admin tasks to keep my hands from wandering near food! Need to do run after work, never done this on an FD so it willbe interesting how it goes. Hope everyone else is doing ok

Itsaboatjack · 24/06/2013 14:07

Thanks for new thread Betsy.

Dotty glad you had a good Fri night out too. Sorry not been on all weekend to say it sooner.

I was going to be fasting today as its my normal fD, but I'm just not feeling it today so I'm going to shift it to tomorrow and do 16:8 today instead. Best thing about this woe I reckon that you can just adapt it to what suits at the time. I've got a meeting at head office at 4pm and just don't fancy sitting there with everyone with my stomach rumbling.

Welcome Hasywell. Your about the same as me, I'm also 5'7, lost about 30lbs since Jan and just briefly glimpsed the 10s last week. Hoping to see them properly on my official weigh in day tomorrow.

ff I've book marked that recipe for another time, I'll have to wait till I have people visiting otherwise I'll eat far too much of it as salted caramel is my absolute favourite.

Dotty342kids · 24/06/2013 14:20

itsaboat, oh, fingers crossed for those 10's tomorrow but if you don't see them then, you surely will on Wednesday morning after proper fast day tomorrow Smile

BsshBossh · 24/06/2013 14:39

Good article here by Dr Mercola on 16/8 fasting :

lewrockwell.com/mercola/mercola279.html

and quoting Mark Mattson:

Mattson has also researched the protective benefits of fasting to neurons. If you don't eat for 10?16 hours, your body will go to its fat stores for energy, and fatty acids called ketones will be released into the bloodstream. This has been shown to protect memory and learning functionality, says Mattson, as well as slow disease processes in the brain.

Miffytastic · 24/06/2013 15:57

Forkoff I was going to ask a simliar question about 16:8 eating, is this in combination WITH fast days or as instead of?

I am struggling a bit today with fasting, partly I wonder because I didn't have my usual full on sunday tea yesterday... or perhaps because had quite an active/exhausting weekend. Whatever, I feel a bit woozy, yonderly and glum :( Decided that I won't be consecutive fasting this week as I've done the last 2 weeks, so pondering whether to do Wednesday or Thursday instead. ...

BsshBossh · 24/06/2013 16:06

FD check in. Doing well here. No calories so far but not hungry (not even head hunger, interestingly). I think it might be because I ate really well over the weekend. Thursday fasts are usually a bit harder as I don't tend to over-indulge on weekdays.

BsshBossh · 24/06/2013 16:06

How's everyone else doing so far?

EagleRiderDirk · 24/06/2013 16:07

I'm not sure about 16:8 too, though I am doing it occasionally. More by accident than design but normally if I notice its coming up to 16hrs, I try to eek it out.

Have 16:8 the today and yesterday and will fast tomorrow. I fully intend to go back to normal eating on Weds and Thurs though, and am looking forward to it!

IDismyname · 24/06/2013 16:11

A belated check in from me on another FD. I'm pretty active on Mondays - go to a dance class, walk the dogs and do a pilates class, too. It works because I'm not in the house!

Have just had a miso soup to keep me going until supper...which reminds me - I've got prawns and I've got spinach - any ideas??!!

Miffytastic · 24/06/2013 16:23

BsshBossh - badly! see ^^ !

bsshbossh fd check-in. Has been a pretty easy day. Mostly at home, but did go up to the local shops (in the car) to buy food for tonight. Stopped off at Costa and an equivalent of green tea, I think it was something jing. About half an hour later felt really nauseous. Am okay now though. Note to self: never drink this tea again Grin, especially on an empty tummy.

Am about to start dinner. Eating this in about half hour with boiled rice and veg. So looking forward to it.

BetsyBell · 24/06/2013 16:48

FD here. Just had to endure kids eating waffles and fruit after school but had a pint of very diluted cordial which I hope will see me through to Laska's aubergine & chickpea curry I'm having at 6pm. I was about to cave in and have a cold boiled egg with ham but I don't think I need to now.

I broke my fast with lunch after 19 or so hours but would like a full 4 hour gap before eating again. I have learnt to keep out of the kitchen as much as possible after school and then I am far less likely to eat. Need to practise this discipline on NFDs though, FDs are easier in a way.

Ruby We have a few BFeeders on here so hopefully they'll be along to give advice. As you've got twins it would be my instinct to bump up your calories a bit, maybe even double.

Squat challenge update: as per all my 'challenges' (except 5:2) I have been very lax, I got to the 100 mark and then it fell by the wayside. However, I have got into the habit of doing a load of squats maybe 3 times a week (usually about 50) and along with the 1 or 2 runs I do a week I'm noticing small but positive changes to the shape of my bum!
