The 5:2 thread number 36
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!

Ooh, scrambled eggs on corned beef instead of bread. Thanks for that idea, Tip

I'll remember to warm the corned beef too - MW or fried, btw ?

Ooh, TiP and BigChoc - I've lurked here so long it's like famous people suddenly acknowledging my existence!

BetsyBell · 10/02/2014 16:21

Feels good to fast today after missing Thursday's due to illness last week. I managed to start the day with a good load of walking and cycling so it's also feeling good to have got muscles moving again.

Let's face it, after a week of feeling grim everything feels good!

I'd forgotten how quickly my bod slides into podginess - it really does just take a few days of over-carbing and moving less and everything expands and wobbles.

BetsyBell · 10/02/2014 16:24

biblio Welcome! I loved your post :) - the irrelevance of the junk food aisles is a true NSV of the best kind! I totally relate - I consider swathes of the supermarket as almost out of focus, like a foreign language I don't understand. And yet if you told yourself you were categorically not allowed that stuff then it would be desirable.

That's why this works.

bibliomania · 10/02/2014 16:33

And yet if you told yourself you were categorically not allowed that stuff then it would be desirable

That's absolutely it! This WOE is a kind of a psychological trick (in a positive way).

IPokedABadgerWithASpoon · 10/02/2014 16:54

Hoping I get to the 'avoiding goodies' stage soon, just about to head into work with its room of treats! Did get some New jeans today though, deliberately bought a bit tight as a reminder not to snack and as motivation to actually get them to fit/be lose soon

ErrolTheDragon · 10/02/2014 17:00

For me, this WOE means not having to avoid goodies all the time - shun on FDs, and decide whether I want them or not on an NFD.

Chocupid · 10/02/2014 17:57

Thanks TIP & Bigchoc wouldn't have been able to eat before Gym.

tiggermummy70 · 10/02/2014 18:02

my weigh in completed 3.5lbs lost for total of 17lbs lost. 7.5 lbs to first goal and more importantly 8 weeks left until I can switch to 5:2 properly.

hope everyone has had a good day Grin

DontBeBlueBeARainbow · 10/02/2014 19:32

I agree with finding foods 'irrelevant'. On FDs I find myself fantasising about the creme egg/bowl of sugary cereal/cake I'll have tomorrow breakfast, but I almost never actually make those choices on a NFD.

However, I've read in awe of those of you who never snack and whose appetite has reduced on NFDs. I personally find that on NFDs when I get a bit peckish, I do snack because 'i actually can today!' rather than thinking 'I'll wait till lunch'. I am eating quite normally and guilt-free, but I wouldn't say appetite has reduced yet. Optimistic though!

DontBeBlueBeARainbow · 10/02/2014 19:33

Saying that though, it seems work is the problem! I don't really snack at home on a NFD...

JemimaJones · 10/02/2014 19:48

Hi, can I please join? I have started doing 16.8 or somedays 14.10 and eating relatively lowish carb as this suits my body better. I have found that when I eat higher carbs then I tend to get stiff and not able to squat down as easily. Has anyone else found this? Also lower carb is best for my IBS ( stops the farting Blush.
Do many of you do 14.10 or 16.8 on its own and not in conjuction with 5.2? I might do fast days, not sure yet. Sometimes I don't eat a lot anyway and can easily be only 700 cals per day. I tend to eat mindfully though and only when I am genuinely hungry and then stop when I am satisfied. Im all for the principles of Paul McKenna in that respect. Can this all be done ?? Smile

Not2bObvious · 10/02/2014 19:50

That's brilliant Tigger, what way are you currently doing the plan? I missed why you can't start for 8 weeks, seem to be doing brilliant as you are! Nice to hear your story Biblio, it's great to leave the obese category, overweight sounds like a compliment when you've been obese can't it Grin
FD done, 630 in the bank and close to a 3 mile brisk walk on the treadmill. Not too shabby me'thinks, starting to feel happy with myself again. I was proper disappointed in myself last week but I feel back in control which is great. Can't wait for my first brekkie since last Wednesday, peanut butter will featureWink

JemimaJones · 10/02/2014 19:52

O by the way, I do 16.8 or 14.10 naturally as I am not a big breakfast eater and tend to not eat till 1.00pm or 2.pm each day. I don't do diets as they cause me great issues and disordered eating so I eat whatever I want as long as I am hungry for it. I have lost 8lb last month with doing my thing. So just wondered if anyone else does this. Thanks.

BigChocFrenzy · 10/02/2014 20:05

This WOE only works for me because I can still have sweet treats - although in vastly reduced amounts, of much higher quality and on some NFDs only.

I'm more incorrigible than Betsy, Tip and some others who have reduced appetite and find junk isles "irrelevant"
Shock Blush
My 5,000-cal choc frenzies are no more, but I enjoy good quality 500-cal puds on most NFDs, with an occasional 1200-cal raid of the pud trolley at a special restaurant. My 2400 TDEE (gym bunny !) allows this.

btw: I stopped my former fav Haagen Daz with choc cookies, muffins, donuts, cheesecake or pie, after I estimated each bowl at around 1500 cals with 100s of sugar grams Shock

Now, they taste too sweet, so not tempting.

jjlou · 10/02/2014 20:06

Was supposed to be a fast day here, but lovely colleague brought in some of his Mum's spanakopita because I said I loved it. Only had a small bit, but full of filo and cheese. Was delicious.

Just finished body pump which will hopefully make up for it (a little bit at least).

8lbs in a month is fantastic Jemima.

BetsyBell · 10/02/2014 20:15

bigchoc Make no mistake - I don't consider high quality puds or decent chocolate as 'junk'! I'm talking biscuits, crisps, low grade baked goods: the over sugared, over salted, trans fat containing stuff.

My calorie bomb days seem to be raw nut and dried fruit based - I eat far too many, but I love them so.

Jemima I think there's quite a few 16:8 types on here - I tend towards it on non fast days but I do need the fast days to reset my appetite.

And to stop me pigging nuts 2 days a week Grin

zedzedzed · 10/02/2014 20:19

So...at last, when all the snotty/pukey/fevery babies were bathed and in bed I sat down to eat my Thai spiced soup but, sorry if you're eating, it looked too much like the poor baby's vom so I binned it and opted for soft bread and Marmite and a couple of slices of Gouda instead.

So by hook or by crook today has been a sub 600 FD, against all advice not to fast when you're ill, but only because I just couldn't face real food yet.

I'll have an early night (hopefully not interrupted by poorly babies too often) and eat up on my NFD tomorrow as throat/bones/head all feel on the mend.

Well done Losers and The Recently Un-Lurked!

BigChocFrenzy · 10/02/2014 20:21

A few folk here do 16:8 or, as allowed for women, 14:10 on its own, without 5:2.
However, to lose weight you still need the same calorie deficit. It is just personal preference which method you find easier.

The average weekly deficit on 5:2 with the 2 FDs is 3000 cals. On 16:8 without FDs, this would mean averaging about 430 cals below TDEE each day.
Some folk find that only eating during an 8-hr period that they cut out a meal without wanting to eat back those calories at the other meals. Others find they can exceed their TDEE even on 20:4 if they don't monitor calories.

BetsyBell · 10/02/2014 20:23

I have never quite been able to relinquish my NFD weekday 4pm snack monster dontbeblue (did I mention the nuts?!)

I did try not nibbling post school/work but it made no difference to my weight. I do have a tiny lunch most days and usually no breakfast so I think it's fair to say that I am simply hungry at that time! I tried upping my lunch but that made no difference either.

It's all fine unless I start on the toast and marmite...

BigChocFrenzy · 10/02/2014 20:32

Well done on the weight loss, Jemima.
You've found a form of IF that suits you. We think fasting brings health benefits in addition to those from weight loss, so all forms of IF would have these.

My 2 FDs are usually ultra low-carb and I feel these 2 days give my system a rest. I tend to have 4 NFDs on medium carb slightly below TDEE and one splurge NFD of high carb, well above TDEE. I rarely eat breakfast, so mostly 16:8 as well.
So, I combine carb cycling with calorie cycling and IF.

OP posts:
TalkinPeace · 10/02/2014 20:34

Bigchoc
I have a massive built in advantage on not snacking : I do not have a sweet tooth and am allergic to chocolate.
Therefore I've always been able to ignore the confectionery and biscuits aisles.
I also did not eat potatoes until I was nearly 10 and am still not wild about them - including crisps.
So not snacking has always been my way.

Wine, cheese and pasta on the other hand GrinWink

Well done to newcomers like Jemima starting with 16:8
I do think that is a really good way to start to retrain your brain, and so long as you do not go mad in the 8 hours, you will get a calorie deficit even if not trying much.

Just remember

Peplum41 · 10/02/2014 21:37

Hi all, especially you de lurkers.

Just wondered if any one does 5:2 and 16:8?

Also, does anyone chargrill veg on a George f grill, any tips before I freegle the thing and maybe regret it.

Glad to hear you managed a short sniff and stroll with sausage dog errol, ease him in gently.

zed another sickie with sick babies! Is this thread contagious or something.

FD , not especially eventful, but looking forward to tomorrow tbh. Creme egg. I will want it. No debate.

Peplum41 · 10/02/2014 21:42

Feel I must quantify that creme egg will be earned first with a dog walk and gym visit all in a continued fasted state.

Glad to see you back to your usual breezy self betsy you keep eating those nuts kid, sure they do you good. I have something of a date habit myself.
