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!

Lovely story, Bssh and congratulations on achieving GOAL

I see you have lots of healthy NSVs as well, which I think is such an important part of this WOL.
Great encouragement to newbies to read about your achieving a completely new body shape.

Well done bssh! Now don't be disappearing off to the maintainer's thread too much, will you...your expertise is needed here!

DorisAllTheDay · 02/02/2014 14:08

BsshBossh thank you for posting your review. It's really inspiring to me because we started from similar places. I was 15 stone 7 in summer 2012, BMI 38 and dress size 22/24. I lost 6 stone between August 2012 and October 2013 through calorie-counting and exercise, but I was starting to put it back on - from early December 2013 I found myself with an insatiable appetite for carby treats (especially pastries, croissants and my old friend and enemy the bagel) and by the start of January I was back up to 10 stone 8 and heading in the wrong direction very fast! I've yo-yo dieted since childhood and I'm terrified that this latest and by far the most successful of my weight loss attempts will end the way of all the others, with me putting all the weight back on and then a bit extra.

So I was attracted to 5:2 in the hope that it's something I'll be able to maintain for the rest of my life, and I really, really hope I'll have the outcomes you've said - especially a decrease in appetite and no guilt around food. The prospect of the rest of my life spent either very overweight and feeling terrible about it, or else continually feeling that I'm denying myself the food I want, is not a good one. Thank you for posting, and you've inspired me to keep going even though I'm halfway through a difficult FD and I didn't get the result I wanted on the scales yesterday!

Oh, and congratulations. Have some Flowers.

BsshBossh · 02/02/2014 14:15

DorisAllTheDay appetite reduction is a well-known and popular outcome of fasting c.f. other forms of dieting (I think many other long-termers can confirm this in relation to their own experience?) and I really can't imagine over-eating again. Never say never of course, but if I continue doing some form of intermittent fasting I can't imagine I'd need to worry about over-eating again.

DorisAllTheDay · 02/02/2014 14:21

Sorry to hear all the weeing and pooing difficulties. I don't think I have any advice that's not already been given, but take care of yourselves and as far as possible, try not to get emotionally drawn-in. It's hell while it lasts, but it does pass. and then they move on to being moody and stroppy

Welcome, Neverletmego. I also had problems sleeping after FDs for the first couple of weeks. It's fine now, and if anything I'm sleeping rather better than before. I second LilyJo's advice about drinking - lots of water is helping me get through FDs and also helping me stick to TDEE on NFDs.

Lilliput I also have the issue of losing weight from my boobs while my pot tummy stays put. I like Zed's idea of putting aside a pound for every pound lost towards a really nice bra. Wish I'd thought of doing that - mind you, I seem to have spent a fortune on clothes ever the last year, far more than a pound for a pound! I am keeping our local charity shops in business.

Dogmatix, congratulations on seeing that 9! Great milestone.

BigChocFrenzy · 02/02/2014 14:54

Bssh I must say that appetite reduction is something that hasn't happened to me and after several months on 5:2 probably won't happen.

Interestingly, reflecting on that "Fat v sugar" Horizon program, after yesterday's massive intake of both low-GI carbs plus mostly mono-saturated fat, I had unusually high energy during training today.
Hmm
I enjoy intense fasted training, but normally restrict it to 60-90 mins. However, I have done 2 ½ hrs of spin, heavy lifting, abs followed by a brisk walk in the sun and I still feel energetic
Hmm
I've just broken a 15hr fast with 300 cals (2 low carb shakes) and feel quite full.
I'll have another walk later, maybe work the smaller muscle group with dumbbells and then a sauna.
I'll keep Monday as a 2nd low carb FD - I've done 45-hr fasts before, so should be fine.

ernesttheBavarian · 02/02/2014 15:18

wow BsshBossh, I'm massively impressed. Well done. Really. That's brilliant.

So many typos in my last post. wrote it on phone. Of course I meant 2 days with 0 carbs leads to no more sugar craving and massively reduced appetite.

I have stressed about me weight for so many years and I finally feel positive that with this WOE I can get it under control and reach my goal and cease to stress about it, and actually succeed. Then I read your post BsshBossh and it is really inspirational and encouraging. Thank you Smile

DANGER : Anyone taking OxyELITE Pro (fat loss / fitness supplement) - STOP!

I received a free sample with some sports goods and just now Googled it:
it's been withdrawn from sale in the USA after 29 cases of liver failure and several deaths in Hawaii alone, see LiverFailure

Before taking ANY supplement, do Google it. Companies may continue supplying goods that have been banned / withdrawn as dangerous in other countries.

bssh well done! I knew that target would soon be smashed. Thanks Wine and Biscuit for you (or just whichever one you feel like Wink)

Today has been far better with dd. We told her that if she kept her knickers dry she could have some chocolate. She nearly made it so we said OK, try again. She nearly made that too so try again we said. Then we took her out to the play centre. She didn't wet at all whilst there so we made a big fuss and gave her a Biscuit (forgot the choc der). A bit of shopping later and she was still dry so we gave her a special dessert with lunch. A bit more shopping and a trip home and she was still dry. She proudly announced it so she had a small bit of choc and a fuss. Fingers crossed this gets her thinking about it again. The problem with dd is carrot and stick only works after she's gotten the carrot the first time!

mrsf that sounds like a complete nightmare.

lily that sounds familiar. Dd is very capable of saying no Sad

MrsF / Eat
toddler training ... I'll be mean here (and I know Toffee is still hacked at me but we'll sort it)
neither of my DCs had any " retention" problems - probably because I did not know they existed and did not care.

DS takes ages, but speeds up when I unplug the router ...
for littler kids, I wonder if the old fashioned "be ready or walk" would work
as its actually all about control not food!
mums with issues often pass them on

zedzedzed · 02/02/2014 18:18

Um...ok.

So I've done all my usual boring Sunday maths and found that my (unregretted) daily salted coffee cupcake addiction would leave me with only a 6000 cal weekly deficit if I ate up to my usual 10-20% under TDEE today, and as I'm being very careful to always have a theoretical 2lb loss p/wk, I've had a mini fast of 1000cals today...

OH MY GOD !!!

It was so much harder than a proper fast; no way can I ever go back to low cal, I feel ravenous and deprived and binge-y, or I would if I didn't know I had a FD tomorrow followed by a day of lovely normal food on Tuesday.

So grateful I found this woe or I fear I'd struggle forever more. [grins] Thanks

PS Just tried on my brand new size 18 Xmas prezzie nighty, which was too small on Boxing Day, and it's now swimming on me! Huzzah! A nice wee Sunday NSV for Zed.

BigChocFrenzy · 02/02/2014 18:44

Zed Mini-FDs are often just when an FD fails is clearly going to exceed the calorie limit.

I sometimes do a mini-FD if I plan to go out for a late meal, because otherwise, I find a substantial supper tends to go to the hips. I then generally skip pud.

I personally find mini-FDs are only tolerable if I skip breakfast and lunch (or have a low carb shake) and save almost all the calories for supper.
I tried having chicken or veg soup for lunch, but that made me very hungry until supper - that seems to agree with your experience.

How does anyone else do mini-FDs ? ^^

OP posts:
Eatriskier · 02/02/2014 19:03

I tend to mini fast rather than proper fast on fds. Mainly because I create too much calorie deficit for me otherwise. But like bigchoc they're liquid only until dinner time.

Tomorrow's Fd will be spiced squash and lentil soup with homemade spelt bread. And something thrown in for dessert. Maybe a combo of Greek yoghurt, digestive biscuit, crushed nuts and a touch of cocoa or crushed dark choc. Hmm actually I want my Fd dinner now Grin

Thanks guys...PS my baked potato weighs 80g less after cooking...so much liquid I guess, who knew? I wonder which weight I should count?

BigChocFrenzy · 02/02/2014 19:30

Zed Raw and cooked weights are different due to water content, so you should take either raw weight and mfp calories for raw pots, or cooked and cooked.

zedzedzed · 02/02/2014 19:32

I left a wee toffee message on her recipe thread this morning...nada. Sad

zedzedzed · 02/02/2014 19:36

Thanks BCF Hooray on the potato front, I can have a yoghurt and a hot choc now then...quick before my FD starts!

BigChocFrenzy · 02/02/2014 19:47

The Horizon Fat v Sugar program surprised me with the bad effects of high fat in just a month. This contradicts several other studies of up 6-12 months comparing low carb and low fat, where low carb was more beneficial., without any health issues.
(we don't know longterm low carb effects, though. I personally had to stop low-carbing after several years)

Of course, both the high fat and high sugar diets were wildly extreme and a study of only one DNA. Also, the twins might belong to the section of the popularion that reacts badly to high fat: I vaguely remember about 25% of people can't cope with high fat; about the same with high sugar.

It seems we need a mixture of fats and carbs, but also need to avoid food that is 50% fat +50% sugar, because that sneaks by the off switch for our appetite.
Hmm
Complicated - No wonder so many are putting on weight !

WipsGlitter · 02/02/2014 20:41

I'm giving this a "final February" go. I find the fasts easy but lose very little weight. 1lb seems to come off and on. Might try not weighting myself for the month!

postmanpatscat · 02/02/2014 21:02

choc it was on BBC, might still be on iplayer?

neverletmego · 02/02/2014 21:18

choc, it's on youtube, just type horizon fat v sugar :)
