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!
Come join us, and tell us about your experiences with this way of life!

Hi all. FD for me

had a super hungry day yesterday out of nowhere so hoping I get through this OK. I considered postponing due to feeling a bit rubbish but seem to be handling it so far, so I'll continue!

HandMini · 21/01/2014 12:14

Hi everyone, good luck those doing a FD. I did one yesterday, and it was my hardest yet for some reason, but remember how great you will feel when you wake up tomorrow - cleansed and NOT HUNGRY!

I did a run this morning as soon as I woke up, so no breakfast or coffee and felt fine. I actually find running the morning after a fast day easier

WhenSheWasBadSheWasExhausted · 21/01/2014 12:23

toffee I love that you accidentally weighed yourself Grin congrats on victories though.

grace sorry it's not gone well

ravenous very Envy of your weight I'm only 5"7 and am aiming to get down to 10 stone 5

Well today's fast is going ok so far. 88 cals consumed so far and will try and put off lunch for another hour.

Tiredemma · 21/01/2014 12:26

Weird.

I am just not hungry at all today???

Im going to have an omlette in a minute but feel that im only having it because its a NFD.

Anyone else have NFD's where they dont really feel an urge to consume like a pig?

HandMini · 21/01/2014 12:31

TiredEmma - yes, the NFD after a FD I very rarely feel hungry until lunch time (but usually try and eat a light breakfast to stop myself piling all my calories into the evening). It's great isn't it!

ToffeeOwnsTheSausage · 21/01/2014 12:33

I forgot to make soup and bread with making the twirls so having tinned soup but what can I have with it? Sliced bread is not good for me. Sets off the munchies which I don't want but I do feel like I want something more than liquid.

ToffeeOwnsTheSausage · 21/01/2014 12:36

I am having cubed feta in my soup. Yum.

lubeybooby · 21/01/2014 12:48

Found this interesting Pinterest board full of mega low cal FD recipes (if you click the links back to the blog they are pinned from) www.pinterest.com/eclectic_gal/5-2-diet-recipes/

Eatriskier · 21/01/2014 12:52

grace being told to eat more is one of the more special elements of this woe! Wrt eating back exercise calories, it's up to you. You could eat them all back if you wanted (but be aware that these are often estimates so you may want to eat slightly less than all), eat some of them back or eat to your sedentary tdee and 'bank them' so that you can have a couple of guilt free splurge days

CinammonGirl · 21/01/2014 12:56

First FD of the week, doing fine so far. About to have a bowl of minestrone soup fir lunch then small chicken breast with loads of veg for dinner. Think I will have enough cals left for a mug of options hit choc before bed, yippee! This is DH's first FD and poor lamb says he's so hungry but he did insist on cycling to work this morning!

The real test will come this afternoon when I go to visit my gran and am faced with trays of homebaking!! I can do it though, my will is strong!!

CinammonGirl · 21/01/2014 12:57

hot choc!

lubeybooby · 21/01/2014 12:57

Tiredemma my appetite hasn't decreased much on NFDs yet but I can see how it could happen. I've had no trouble sticking to or being a bit under TDEE though and it's definitely made me appreciate what I'm shovelling into my mouth more and less ignorant of calories.

NSV today - had to have new holes put in my favourite belt Smile

Tiredemma · 21/01/2014 13:08

grace- ive just read a post on the MFP site of a woman who got down from a US size 20 to a US size 4. She said that she never ate her exercise calories and 'banked' them once a fortnight (a saturday) and more or less had a bit of a 'binge'.

I exercise every day and generally 'gain' an extra 270-400 calories but very rarely use these to be honest.

DottiestDoris · 21/01/2014 13:22

Oh goodness me! I've read a bit about the importance of exercising on this thread (other than my daily toddler-paced walks) and though I'd give a few sit ups a go to help shift my babyweight-inflicted saggy midriff. I used to do hundreds of the things. I lay down and went to start and... nothing happened Blush Where have my stomach muscles gone?! I eventually did ten, but I had to do a few little cheats to get there.

I'm very positive about the 5:2ing but have just realised that I might need to do some hard work on the muscle building too. Babies...why do we have them?

Breadandwine · 21/01/2014 13:25

toffee I love that you accidentally weighed yourself

And I love the extra sprout you cooked for yourself, toffee!

I forgot to make soup and bread

Here's a quick bread you can make in 13 minutes! - from having the thought, to tucking in!

Cost? Absolute pennies! Smile

BsshBossh · 21/01/2014 13:26

Anyone else have NFD's where they dont really feel an urge to consume like a pig? Tiredemma yes, me too.

Toffee I'm having cubed feta for lunch too today (NFD) but in a puy lentil and lamb stew that DH made last night for his dinner.

clarinetV2 · 21/01/2014 14:03

Anyone else have NFD's where they don't really feel an urge to consume like a pig?

If only! After my hardest FD yet yesterday I could easily eat the contents of my Sainsburys local bakery section and still be hungry. I was aiming to make today's NFD a low-carb one because high-carb food is my downfall - once I've started I can't stop. However, I weakened at lunchtime and bought some yummy flapjack from my work canteen. Can someone send me some 'don't really feel an urge to consume like a pig' vibes please?

RavenousRunner · 21/01/2014 14:14

Lunch out again - merguez sausages with Turkish salad and (white) pita. Not too bad calorie-wise, but the white bread combined with a coffee means my heart is going like the clappers. Think I may have to plead indigestion tomorrow so I can have a peaceful soup at my desk!

Eatriskier · 21/01/2014 14:16

I quite often find myself ravenous on a Tuesday after a Monday fast, but not so much on a Friday after Thursdays fast. I don't know if this is more to do with the fact I take the dcs to. Swimming lessons on Tuesday so mentally I feel hungrier. So today I decided to make my deviant porridge even more deviant. Jam, peanut butter and about 15 pistachios ground to chunky. Was blooming gorgeous and I wasn't dying for the dcs to go to bed as soon as we got home as, though hungry, I felt like it could wait for a change. Was lying something stupid like an extra 60 calories too, far better than a lot of things I've supplemented breakfast with in the past.

On a Sad note, today was dds last 'baby' swimming lesson. She goes in on her own with the instructor (and group obviously) from next week. Where's my baby gone Shock

madhairday · 21/01/2014 15:35

Really interesting to hear people's stories. I am confused about the eating more to lose more though - ie going up to TDEE on NFDs. I really struggle to do this, as I just can't seem to eat that much. I tried slimming world and put on weight as it was much more than I usually ate. Is it just that my metabolism is screwed up? I know it is, from years of chronic illness and sudden large weight losses through infections etc, can't help. But if I ate 2,000 calories on NFDs I'm not sure I'd lose any, or is it that my body would get used to it and I would lose more? Not sure...

On a great note I have lost another 2lb this week so 4lb in 2 weeks, this is the first 'diet' which has done anything for me in years, feel good on it too, feel very positive about it :)

almostthereagain · 21/01/2014 15:36

Doris I remember doing that & only managing 2 proper sit upsShock 2!! Good for you for making a start. I have just started the 30 day challenges, maybe that could work for you? I'm only on day 2 but need to follow something to make me do it. Am very good at finding absolutely ANYTHING else to do rather than just get on with it!

ErrolTheDragon · 21/01/2014 16:07

madhair - 4lb in 2 weeks, wow!

I suspect that while there is a good reason for 'eating up to TDEE', people do vary in all sorts of subtle ways and the TDEE calculated from a website isn't going to be accurate for everyone. I guess by definition, if you ate your calculated TDEE and gained weight, then your true TDEE is lower - either because you're less active or your metabolism is fantastically efficient or - well, there may be other variables.

lubeybooby · 21/01/2014 16:13

finding this FD a lot easier so far than I thought it would be given how crap I felt this morning. Can't believe I've made it to 4pm so far on a bovril and a yogurt.
