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!

Marking my place. Back at work now and seem to have non-existent time, so I haven't read most of the thread.

Sorry to hear you are ill MrsF. It's just so hard when your children are also ill. Thanks

I am afraid my Sunday was a huge blowout with food. I didn't even log it on MFP because I knew it would be terrifyingly huge. So last week, though managing 2 fast days easily I had three days where I am sure I was over TDEE Shock I know that won't work very well to remove 10-15 kilos, so I am starting a fresh this week. I'm fasting on Tuesdays instead of Mondays because Monday is my swimming day and I can't seem to manage it when fasting. So I had a big swim yesterday and didn't overeat. Today I fast. I've just made some vegie soup to take to work and we'll have fish for dinner.

Yesterday a friend at work called me a "skinny minnie"Grin I told her she was being very kind but I am definitely not skinny, and she said I've lost enough that I look a lot slimmer. Chuffed about that Smile It will keep me motivated to sail on to my goal....

BigChocFrenzy · 03/02/2014 23:02

Positively 16:8 means eating only within an 8-hr oeriod each day, e.g. only between 12:00 and 8 pm, with total fasting for the other 16 hours.

However, no method you choose to lose weight will work unless you achieve a calorie deficit. There really is no magic "eat all you want" trick, whatever any book or diet may claim.

From what you posted on 5:2, you have a low TDEE, but you are over-eating on NFDs. I think I explained that with your TDEE, you would only achieve a 2000 weekly deficit, theoretically ? lb per week on 5:2 and then only if you kept to TDEE on NFDs. Folk with a low TDEE just have a tougher time losing weight than the rest of us.
Sad
On 16:8, same as with any standard calorie restriction diet like WW, you would need to achieve the 2000 calorie deficit by eating daily about 285 calories below TDEE, so only 1215 calories. With 16:8, you would eat these calories only within the 8-hr period.

Hope this helps
Smile

Positively I calculated the figures for 1500 TDEE, which I think was about your TDEE.

Postman I did wonder about a polyp having seena thread on here, but the GP had a look and a prod and said nothing seemed out of the ordinary. If it is a one off then I shan't worry, but she said I am to go back if it happens again.

DS2 now seems to be poorly Sad he has got little spots round his mouth and on his hands and feet, and a temp and is very unsettled. I'm guessing no preschool tomorrow, which is frankly a PITA because I have got a haircut booked which I shall have to cancel.

LilyJoAndMe · 04/02/2014 06:58

Good morning campers Grin
Hope all the FDs went ok for those who were doing them yesterday. I was and I had a lovely vegetable curry - thanks to Breadandwine and his lovely recipes. So came in at about 300cals minus 20 minutes of exercise. So happy about that.
Today off to a good start just done my exercise on yesterday's Fast tummy and I feel fine .
So good luck to all the Newbies and to all those on FDs today.
Keep drinking.Smile

tiggermummy70 · 04/02/2014 07:01

Morning all Smile [waves]

Doing happy dance today scales finally read below 40% Grin body fat.

told my councillor yesterday of my plans to phase in to 5:2 when I finish their study and she seemed ok with it. Now just got to motivate DH as I found out about it researching how to improve his health as he is borderline for type2 D. Sad Runs in family, his grandma wasn't o/w still had it for 20+ years, his mum also has it......

hope everyone has a good day.

LilyJoAndMe · 04/02/2014 07:11

Great news tigermummy. Has your DH watched the Horizon programme on fasting ? That might help convince him.

To all of you who've got the lurgie or who's DC are down with it, take care and rest as much as you can . I hope'll all be better soon.

neverletmego - I felt absolutely awful on my first fasts. It definitely has got better for me- which makes me realise that what I was putting into my body was really not doing me any good before I started this 5:2 stuff :)

Eatriskier · 04/02/2014 07:12

Early morning here in the riskier household. DS woke an hour earlier than normal, waking DD in the process. Gro clock normally rules but given the issues we've been having pt with her and with DS being up I figured it best to let her come down. So now there are 2 DCs running about, DH trying to go to work and me out of it without my morning coffee. Already looking forward to my tuesday Wine.

tiggermummy70 · 04/02/2014 07:21

Hugs riskier.
our girls are up by 6.30 every school day. we are supposed to leave house by 6.50. More time given longer they take???
Tuesdays are my reset day as I leave early so I can finish to take them to swim lessons tonight. Its my chance to catch up on forums and read on train without constant noice. Love em but its nice to have break.

positively9something · 04/02/2014 07:21

Bigchoc - thank you once again always very helpful Grin

Well I an mange the fast days ok but it is the non fast days that I struggle with. I think it's that I need to up my exercise big time.

Yesterday I had to walk to school
And work as I didn't have my car, doing that everyday means I would be walking for an hour and a half each day in total which I think means I could defiantly consider myself lightly active, then if I did make it to the gym 1-2 days for a weights class I think that would be great. But it means waking up so much earlier and I can't be bothered even though I quite enjoyed walking. I think it's just because I'm not used to it Confused

I've even been considering no carbs which I hate ConfusedConfused to loose weight then maintain with 5:2

BigChocFrenzy · 04/02/2014 07:26

Well done, TiggerMummy You have improved your health and your body must be feeling lighter.
Glad to hear you can join us 5:2ing after your current program.

good morning,

NFD today, very happy.
it's true, lilyjoandme, I was feeling superweak and fait yesterday but then thought that I actually brought it to myself - att the sugar I've been eating...
slept terribly though, not happy about it as work will be v.hectic today...

happy Tuesday everyone!

zedzedzed · 04/02/2014 07:43

Doris you walked home 4 miles, I'm unrepentant for The Buttermint tea Song as it clearly helped you power through...your pie verses blow that muppet's efforts away btw.

NFD here (look away FD-ers) toast with butter AND peanut butter...OMG! Just one slice and one tsp of each, but still!

DH was totally checking me out this morning, (he's been sweetly concerned but smartly silent these last two pregnant years as I've grown from a size 10 to a big 18, loving me the same but worrying for me) well just now he checked me out (and I actually let him) and then he said 'You've lost so much weight already I can see your waist and hips again, well done!'

Grin

It's my 5:2 Month-iversary this week...I will either weigh-in or re-try the dreaded size 16 jeans.

Happy munching NFD peeps (light lunch for me, later we'll have a peppered steak, a garlic and stilton field mushroom with rocket salad and then a rhubarb fool).

COME ON FD-ers POWER THROUGH,GET BUSY,DRINK UP,POST HERE FOR SUPPORT,GO WALKING AND REMEMBER.....YOU REALLY CAN HAVE IT TOMORROW!

BigChocFrenzy · 04/02/2014 07:49

Positive Further ideas:

1)The only diet I know where genuinely almost noone needs to calorie count is ADF: Only 500 cals every other day means people have to be very greedy not to have a large calorie deficit , particularly with exercise.
Since you maintain OK on 5:2, you probably don't over-eat a lot.
However, ADF does affect your life more than 5:2 and is not for longterm.

  1. 16:8 is basically cutting out a meal and not increasing size of the remaining meals you have in the 8 hrs. Many people automatically eat more in the 8 hrs unless they monitor caloires.
    However, you might feel less hungry with only 16 hr fasts. If you try it for a few weeks, then do so with calorie-counting to ensure a daily deficit.

  2. Fast 5 (BreadandWine has a video link) is eating only in a 5-hr window, e.g. 1-6pm, then fasting 19 hours.
    Most people can do Fast5 without calorie-counting because they can't eat up to TDEE in the very short eating window.

ErrolTheDragon · 04/02/2014 07:51

neverletmego - last year I was doing5:2 and also exercising more (30 day shred) and the scales turned around from gradually creeping up to creeping down - about half a stone in all. The exercise started in the summer, the 5:2 a bit earlier. So you can do this without calorie counting on the NFDs, obviously just don't splurge. I found that I was happy with smaller portions of carbs anyway which doubtless helped. But I was eating formerly 'forbidden' foods like chocolate! Smile.

positively walking for an hour and a half each day (or some days)would definitely help, especially if you walk fast - which could give you an extra 5 mins in bed Wink. If you're time-short then there is quite a lot you can do at home - apart from the shred type dvds, weights and press-ups etc per BigChoc's post to Handmini. I think you're at the point where you know what you want to achieve, you know you need to change something; its up to you to figure out how to do it in a way that suits you best - you can do it. The Nike slogan is spot on for a fitness company Just Do it. Smile

Handmini - BigChoc is helping me with upper body stuff on the exercise thread, so there's info there for the scrawny of arm - my goal is to do proper push-ups (I can do 'girlie ones now' after doing shred a couple of times through) - a combination of holding planks and sets of inclined press-ups gradually working lower, and now also the weights sets she suggested.

ErrolTheDragon · 04/02/2014 08:01

zed - it's lovely when a DH/P gets it right like that. Smile

Well, I came in a shade under 500 yesterday FD which is good because today is DD's birthday, we're having Chinese for dinner (M&S so not quite so oily/salty as a takeaway) and DH bought a little birthday cake too. (little but 6x295 cals per slice iced fruit cake!) It's the first year DD hasn't had some sort of party or sleepover (though she may go into town with her friends after school) which I feel a little wistful about.

Right... I need to get off my lardy arse and shred, because no-one else is going to do it for me. Smile

Felix90 · 04/02/2014 08:18

Just a quick one to say I've just had my first weigh in and lost 7lb!!!!!!! I've never been one to have a huge loss in the first week so I'm so happy Grin

frenchfancy · 04/02/2014 08:18

Grin for Zed's DH. Try the jeans zed we want to know.

zedzedzed · 04/02/2014 08:42

Yay Felix ! That's amazing! Woo-hoo!

Will try on the jeans Friday fancy after 2nd FD.

Gulp.

Nursery run now, then furniture painting, then steak and fool shopping.

almostthereagain · 04/02/2014 09:17

zed fantastic & so motivating for you now go & try on / weigh, can't believe you didn't do it pre toast & pb! No way could I give up my scales for a month, hats off to those that do, I'm a compulsive weigherBlush
Woo hoo tigger & felix
*mrs F8 poor you, it's one thing after anotherSad All the stress has probably not helped your immune system. So hard to look after yourself when you're a mummy but I hope you can take some care.
To the 1500 TDEE pp (sorry can't remember who) I am same & I aim for 2 days 500, 3 around 1200 then 2 1500 although I do go over. I manage to keep the w/e days around target by choosing 1 splurge meal ie delish b'fast, lunch OR dinner with alcohol p/day rather than 2 whole days + friday night undoing the weeks hard work. I look forward to 'that' meal & try to eat for fuel otherwise iykwim. I def find trying to make the majority of what I eat nutritionally dense, good carbs sugar & white carbs as intended just as occasional treats I am able to lose. hthSmile

Megrim · 04/02/2014 09:18

Fool shopping? Hmm I can suggest a few for that list.

Well done Felix. Have you measured yourself as well?

Felix90 · 04/02/2014 09:28

Thank you all!

Megrim I forgot to take measurements Hmm I will do it today if I get time!

Felix well done :)

HandMini · 04/02/2014 09:57

BigChoc and Errol - thanks very much. February is going to be the Month of the Push Up for me. I'm going to check out the Exercise Thread and videos and give myself a few days to sort out what I'm capable of (likely to be ZERO at the moment) then set a goal for month end.
