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

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!

Excellent stuff toffee lots of victories going on for you this morning :)

See once you're chomping on the high % stuff BCF you know that means you're craving chocolate (entirely sensible) not just mainlining those naughty white crystals.

1200 calories on decent desserts sounds perfectly reasonable to me - got to be done occasionally - s'all about balance innit?

almostthereagain · 21/01/2014 08:52

Well done toffee Such a good feeling getting to a new low isn't it?
hopeful & VV it's tough when life gets in the way whether its a sleepless night or a lovely unexpected treat. We have to live & just keep some balance as best we can. If nothing else I look at it as at least I'm not gaining, slow & steady wins the raceSmile

DinoSnores · 21/01/2014 09:01

Good FD yesterday. I surprisingly didn't feel hungry at all and wasn't tempted by the chocolate hobnobs at the toddler group. I think exercising in the middle of the day made a big difference and knocked off my appetite until dinner. Weigh in yesterday was down another 0.7kg, so I'm pleased that it is all sliding gently back to where I was before I was pregnant with DD2.

Well done toffee on your SV and NSVs!

jobyloo, I think the Fast diet website says not to replace exercise calories on FDs, so I am sure you'll be fine. I think the difference with long term fasting and intermittent fasting is that IF is fine because you're always eating normally/properly the next day.

grace you may be eating too little on nfd. Quite a few people here and on other places have found they lose more weight when they eat more on nfd.

turkeybaby · 21/01/2014 09:21

Oh no gracehol is it totm? Or could it be muscle gain from the exercise? Do you feel/ look slimmer? I know how disheartening that is though! Main thing is not to give up.

Morning all and good luck all the fasters today..

Megrim · 21/01/2014 09:39

I tried some of that Marigold vegetable bouillon stuff yesterday for the first time - wow, it's filling, how can it only be 15 calories?.

RavenousRunner · 21/01/2014 09:43

New one for me today, overslept so went running on an empty stomach and no coffee after a FD. It wasn't pretty, but not as bad as feared. And my porridge with skimmed milk, banana and blueberries after was delicious.

Got home after dinner last night, ate half of a veggie burrito I'd instructed DH to make, went straight upstairs and did kid bedtime stuff, then slobbed out with tea and Breaking Bad. It was much easier than sitting through dinner and I didn't even think about eating more. As I could in theory work til 10 every night and still have shedloads to do I think I may make this a habit on FDs.

Graceholl I agree with Eatriskier, eat up on your NFDs! Especially if you're not doing a net TDEE where you add the calories burned through exercise - if you're exercising a lot your net calories could be down 1200 or so, which will really stall your metabolism.

ToffeeOwnsTheSausage · 21/01/2014 09:45

Hang on there gracehol. I was stuck for ages and eventually lost but prior to doing this WOE I wouldn't lose weight because I wasn't eating enough. When you calorie count it is amazing actually how much you are supposed to eat to maybe keep an eye and see if you are eating enough?

TalkinPeace · 21/01/2014 09:46

vvviola if your schedule goes a bit pear shaped, the other backstop is to do 16:8 ie skip breakfast or supper
so if you go out for a big meal make the meal after just be vegetable soup and then skip one the following day
that way your system still gets a break
but you still have a life.

Yesterdays planned FD turned out odd because DH got home from work v tired and fixed us (small portions of) pasta, bacon and eggs
but he wants to fast today
so I'm effectively doing 2 days of 22:2

and am sitting waiting for the loss adjuster to turn up to see how to fix my roof that leaked over Christmas.

EsmereldaPB · 21/01/2014 09:51

Morning, have been lurking for the last week. I have about 6st to lose altogether and I started 5:2 last Tuesday. I am amazed at how easy I am finding it, I think that this really may be the woe for me. I have done 3 FDs now and each time have managed to get to about 8pm before breaking fast. I am still breastfeeding my 7mo so have been allowing myself 750 cal on a FD but have managed on around 600 each time.

I haven't been counting calories on NFD but I have been trying to think more about what I'm eating and portion sizes.

DH has also decided to fast with me as he wants to shift a little weight and agrees with me that our portion sizes have got a little out of control.

graceholl I'm 5'9", 10 stone 5, and my TDEE is around 2300 I think - I get a lot of exercise. On weekday NFDs I aim to eat net calories of 1800, which as I usually burn about 500-600 calories running means I'm actually eating around 2300. On weekends I don't usually count calories, but aim for a long run which I figure helps out. I've done this since I started on 5:2, and lost 20 pounds in the first 4 months (then fell off the wagon but still only put back 7, which have now gone in 3 weeks of 5:2). It will work, but it's different than a standard diet as you need to eat!

Pfffft...MFP has everything...I'm making cakes for my playgroup Mums (salted coffee, chocolate malt and mini Victoria sponges...yum!) and I've licked the spoon a few times...turns out it's right there on MFP 'cake batter spoon lick, large, 15cals'!

And then I stuffed a whole one in my gob, but it was planned, accounted for and totally worth it!

zedzedzed · 21/01/2014 10:57

Sorry grace cross post. Cakes and poos.

I'm almost 5ft10 and have a TDEE of 2300 or something, I've not managed to eat up to it in my 3wks doing this, scary to eat like a human isn't it?

I'm eating till full, stopping, and logging everything on MFP till I get used to normal portions again. I seem to be 5-700 under most days, I worry too I won't lose on that, but will weigh-in only every 4-6wks so I don't get too depressed by poo/period/bizarre fluctuations; as long as I'm trending down I'll count it as a win.

Good luck. X

Morning all, happy to say I am in much better spirits today after my meltdown yesterday.
I am not on an FD today after abandoning yesterday, but scales were still in my favour this morning. Total loss after first two weeks is 5lb.

The repercussions of work related problems yesterday mean that I have not had chance to have the breakfast I brought with me this morning so may as well wait til lunch now. I could turn it into an FD, but that is tomorrow, and really don't think I can manage two in a row.

Hope everyone is having a good day.

TalkinPeace · 21/01/2014 11:29

graceholl
your bowels will indeed take a while to get used to the new pattern. if in doubt, drink more water and then they will settle down

BsshBossh · 21/01/2014 11:39

graceholl I was a bit sluggish when I first started 5:2 too but things settled more after I increased my cooked veg and water intake on both FDs and NFDs. I also take probiotic tablets and eat probiotic natural live yoghurt daily which also helps.

BsshBossh · 21/01/2014 11:40

Another wonderful thing for sluggish bowels? Exercise! Even just a brisk walk gets things moving for me :)

ToffeeOwnsTheSausage · 21/01/2014 11:45

TiP - hope you get your roof fixed quickly. We were lucky with the storms as only lost a few branches and my bird house. 3 fence panels were damaged but they belong to the side neighbours.

graceholl I am in no way experienced enough to advise but I don't think you are meant to eat back your exercised calories.

"MFP cake batter spoon lick, large, 15cals" - yesterday I logged 8 calories for one sprout Grin.

New recipe on my other thread.

Jobyloo · 21/01/2014 11:49

Lol I love this thread!! It's only here you can get cake batter spoon lick and poo in 2 consecutive posts Grin. Just checked in to see how everyone's doing curve so chuffed that you're feeling better today!
Well been out for 2 mile run, first after outside run since before Christmas. Boy was it slippy but it felt good to be out in the smog,fog fresh air Smile
