The 5:2 Diet Thread number 18! Breaking out the summer wardrobe?

GreenEggsAndNichts · 22/04/2013 10:51

The continuing thread for those of us following either the 5:2 diet or the alternate-day fasting diet.

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 what you like, or approximately your TDEE (see explanation below). Alternate-day fasting is just how it sounds; you fast every other 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 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 calculator to help you figure out how many calories you should be eating in a day.

ADF = Alternate-day Fasting, as it says on the tin, fasting every other day rather than 5:2.

Michael Mosley has recently unveiled a new website to accompany his new book on the subject. Please go check them out, as he's the whole reason most of us are here!

I know a number of people lurk on this thread, as this is currently quite popular. Please just jump in and post if you're new- you'll find a lot of support here.

Here is a list of links to get you started with this way of eating. Please let us know if you find a new article or some other information online:

First things first, here are links to some of our previous threads: most recent one before that another one!

Another thread which breadandwine has started is a good resource for some of the links and tips that get lost in these big threads. In addition to sharing links, we try to condense some of our top tips for fasting there. Keep in mind, we all do this differently, so these are just tips, not rules. This might be a good place to catch up with us if you're feeling a bit lost!

frenchfancy has a recipe thread over here, please post any low-calorie recipes there so they don't get lost in these bigger threads!

If you've been at this a while and are moving on to maintaining your goal weight, there is a thread here to discuss that.

Here is the link to the BBC article regarding Michael Mosley's findings, which was featured on Horizon.

There's a link to the aforementioned Horizon programme here.

A blog post here 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.

A Telegraph article which comments on the diet and gives a brief overview by Dr Mosley himself, very informative if you're just starting. (I highly recommend this for an overview)

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 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.

A BIG THANK YOU to all who have been contributing, btw. 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. Sorry if I haven't given credit where it's due, but it was just enough of a job getting all the links re-copied and back into one post.

Come join us, and tell us about your experiences with this diet!

My third fast today. I had a migraine all day yesterday, and it's still there a little bit today, so don't know how it will go today (I want to eat sugary things when I'm getting over a migraine!). I'll give it my best shot. Dh is taking DD out for a while today, so I'll get out in the garden and do some digging to take my mind off food!

Good luck to all of you fasting today. Nice to know we are doing it together Smile

Dotty342kids · 30/04/2013 09:30

pumpkin and ginger cheesecake? wow, sounds interesting!! And yes Betsy there's definitely something to be said for "out of sight, out of mind".

greenfig · 30/04/2013 09:31

bvb I think talking about a ginger & pumpkin cheesecake on a fast day is akin to swearing Grin

BetsyBell · 30/04/2013 09:43

Sorry greenfig Grin If I can't eat it I have to think about it! It's absurd but I watch cookery programmes and read recipes an awful lot on fast days. Maybe I should stop.

(I'll let you know how it turns out dotty!)

MeNeedShoes · 30/04/2013 09:55

Morning :) Well, a non-fast day and I haven't fancied anything yet so going to wait a while for brekkie. I ended up having a slice of toast at bedtime last night but it was probably just as well as DD had a greedy guzzle ON on the boob :) Was especially pleased as I was going to have a chocolate croissant but managed to just have my toast instead.

Next fast tomorrow so just going to eat normally today. I'm with whoever said it up thread - I have no interest in watching what I eat on non-fasting days. If I was going to do that I would just go back to WW as I know it works in the short term.

akarucker · 30/04/2013 10:05

bvb I do the exact same thing! Watch cooking shows...I walk around the yummy isles in Waitrose, planning my food for the next day!! And as for cook books - that's my porn!!
BTW - where did the v go in bvb??

BetsyBell · 30/04/2013 10:48

Glad it's not just me aka (I know it's not - most of are here because we're foodies right?). V: I got bored of it - just plain ole BetsyBell now! Please feel free to call me bvb though Smile - I'd've changed to that but it was already taken.

Doilooklikeatourist · 30/04/2013 10:57

Hallo , jumping on board .
Had my first fast day , yesterday .

But I may have misunderstood , do you eat just one meal , or 3 small meals totalling 500 cals

On my fast day ...
I had a yoghurt for breakfast
Smoked salmon and some grated raw cabbage for lunch
Chicken breast , courgettes , mushrooms , onions and tomatoes for dinner
All small portions though
Some fresh fruit for a snack , loads of water and some black coffee .

Sounds a lot , doesn't it !

I'm starving now , tummy rumbling away and I had breakfast !

Breadandwine · 30/04/2013 11:15

A huge welcome to all the new IFers! (That doesn't sound quite right when you say it out loud! Sounds as if there's an 'H' missing, somewhere! Grin )

I'm starving now , tummy rumbling away and I had breakfast !
Notatourist That's why you're hungry - by eating breakfast you've told the body there's food available. So it wants to keep eating to lay down fat stores for any famine coming up.

That's why many of us don't eat until the evening on a fasting day.

Have a read of the Tips and Links thread, linked to in the OP.

Don't forget, folks, this is not a weight loss diet - it's a very healthy WOL! And while you're fasting, your cells are repairing themselves - so even if you're not losing weight, you're still doing yourself some good!

DesperateDietingHousewife · 30/04/2013 11:26

I typed a long post last night and promptly lost it-so went to bed instead!
Worked out I had about 410 cals yesterday. Didn't have any dinner, just had a can of Waitrose carrot and coriander soup(90 cals!!) and 3 water biscuits at 14 cals each. Then, I couldn't stop snacking on the water biscuits and had about 6 more-a waste of cals so I decided to just go to bed instead of eating anything else.

Welcome Mozarella-I am the same as you-love sugar and chocolate-they have always been my downfall. I'm finding that I don't want them as much (or should I say, not as much as I would normally!). You definitely think more about what you're putting in your mouth and whether you really need it.

Welcome also Doilook your 500 cals can be used in any way you wish, whatever works for you. Personally, I find going for as long as I can (and filling up on water, coffee, green tea, low cal choc or soup etc), having a small snack of about 150 cals at 4ish, then eating dinner at 6ish works best. I think if I were to eat small portions of food throughout the day, it would make me more hungry. Most people seem to find the same.

ElizaCBennett · 30/04/2013 11:42

Well I tried a 36 hour water fast yesterday! I had been doing well on 5:2 with 500 calls on fast days, but stalled for a whole then started creeping up slowly. Didn't know what else to do but decided to be very strict on fast days and ensure that I was not eating over 500 calls. On Sunday I was suddenly 5 lbs above my recent lowest weight - 11-4!

Enough is enough! Inspired by Bsssh I decided to fast completely on fast days; no food at all. I did have 3 teas with milk, but the rest of the day I had fruit teas. I did feel hungry for a short while in the evening but I often find that even if I have had my dinner so I ignored it. Otherwise it was relatively painless. Weighed this morning, am down to 11 5 1/4.

Dreamt about a big fry up this morning but settled for porridge as did not want to have a big meal to start with. Will eat normally today and think I will do another 36 hour water fast tomorrow and see how it goes.

ELR · 30/04/2013 12:21

aka you should join us on the cookbook thread can't do a link but maybe bvb can?
Basically we choose two cookbooks per month and cook at least two new recipes fom them. You are in time for May it's Jerusalem by ottelongi and kitchen diarys 1 by Nigel slater.

Yesterday was the first day since starting this woe 10 weeks ago that I haven't posted on a fast day, was feeling so cheesed off and disheartened as gained two weeks in a row after seeing a low weight. But this morning I'm back to my weight from two weeks ago but not the low, hopefully I will see that on Friday.
saf keep the faith I think we are on a similar up and down weight thing and I too have Tom coming soon.

Good luck all fasters today.

postmanpatscat · 30/04/2013 12:21

dotty you'll be in the tens soon, they are hiding round the corner to jump out and surprise you!

Eliza well done, I'm another zero 36 hour faster and also did one yesterday. I had a headache by bedtime but just ignored it, slept really well and even had breakfast before I left for work, which is unusually organised for me.

I'm v close to goal so don't lose much, but I have now beaten my original goal of 56kg (about 8st 11.5). I have pushed goal back to 55kg because when I switch to maintenance I want room to gain a few pounds without going back over 9st! I know if the target was based solely on what I see in the mirror then I'd be happy to stop now, it's just psychological.

Have to say that this woe has done wonders for my waistline and tummy, I will measure properly on Saturday but had to get the tape measure out this morning - I have lost more than 3 inches off my waist in less than 10 weeks Smile

Good luck Tuesday fasters!

ELR · 30/04/2013 12:24

Think I'm on a plateau I've been the same weight since 3 April not counting usual bounces!

Miffytastic · 30/04/2013 12:37

Postmanpatscat can I ask how what your way of doing it has been? I haven't lost more than 3cm off my waist in 12 weeks! and altogether dropped 8lbs... How long have you been doign the 36 hrs for? what did you do before that? ADF or 5:2
Sorry if I haven't retained this from previous posts, it's hard to keep up with all the messages & posters but I am impressed with your reduction!

Sunshine78 · 30/04/2013 13:17

Well its lunch time of the day after my 1st Fast and thought I would be struggling with starvation today - but no felt bit hungry mid morning so had a glug of water and it went away!

Yesterday I had 3 small meals but when reading book (yes I got the book) it seems to recommend just breakfast and dinner - all I had was porridge (break) apple and small tub salad (nothing on it) Lunch then tuna and mixed beans (dinner) - was hard adding the pasta to dh knowing I was just having the sauce Envy but i did it - so would I be better off skipping the lunch and adding the cals to the dinner?

EagleRiderDirk · 30/04/2013 13:22

Fourth fast day today. Not quite built up the courage to do a no food fast!

I've dropped just under 8lb now, and finally my glasses aren't pinching my face! Small victories eh?

Good luck anyone else fasting today, especially if you're going liquid only.

ELR · 30/04/2013 13:42

sunshine I would drop the breakfast and then have a small lunch and a slightly bigger dinner. Well done on first fast!

postmanpatscat · 30/04/2013 14:53

miffy

I have done 5:2 for almost ten weeks, with 500 cal fasts for the first six weeks then alternating zero/500 for the last four weeks. I'm a daily weigher and found that 500 cal fast days were making little difference to my weight after 5-6 weeks i.e. I was regaining and losing the same few hundred grams. After a zero fast day, I always hit a new low, bounce a small amount and stay lower than my highest weight from the week before (if that makes sense!) After a zero fast I usually drop between 500-900g, but have been known to stay the same or even gain 500g after a 500 cal fast.

I also work out three times a week and try to walk a reasonable amount between gym days. At the gym I usually alternate: run 8k/run 10k/run 5k plus 3k on crosstrainer. I could only manage to run 3-4k two months ago!

I've lost 17lbs, all over but mostly from my waist, tummy and thighs which is where excess weight likes to sit on my body!

Hope that helps!

Miffytastic · 30/04/2013 15:54

yes that does thank you! does sound like the zero fasting has taken you off the plateau. Exercise is important too isn't it? I am trying to keep up my running and zumba efforts- I'm not sure I could do a zero fast, but more exercise is feasible. Mind you, if someone said if I did X zero fasts I'd be guaranteed to be 9 stone something I might take them up on it... ;-)

SlipperyNipple · 30/04/2013 16:02

Failed fast yesterday. But I knew it wasn't going to happen early on. Fasting today instead.

Can I ask if there is anyone who has lost a lot that hasn't calorie counted on feed days?

BetsyBell · 30/04/2013 16:41

Aka ELR Cookbook thread links - real life reviews of things we've made from that month's books:

April

May

The Pumpkin tart thing is from Smitten Kitchen which was of the two April books - it's going to be late but I'll post my verdict up on the April thread.

I don't have either of the May books so might have to do a web trawl.

Slippery I don't calorie count on non fast days but I know how much it takes for me to maintain or gain so stick to what I know (I've lost a stone since mid Jan). I've been keeping a food diary for ages so I'm generally honest with myself about how much/little I'm eating. I tend to look at my weekly eating habits rather than daily.

Sunshine and Doilook - definitely worth giving the missing breakfast a go - if that sounds difficult them move your breakfast back by an hour or so each fast day. You'll be surprised how your body's expectations adapt and change after a few fasts. You'll start understanding what actual hunger is versus head hunger. I'm fasting today: I ate an apple at lunchtime, just had a cold boiled egg for a snack (I'm finding it hard to shake off a wanting to eat habit post-school/work) and will eat the rest of my calories later. I've drunk lots of hot drinks and water and don't feel hungry at all. I will feel hungry after I've eaten a proper meal though!

A boiled egg really is a great snack. Satiating and filling without creating hunger pangs like carbs do. Lots of fasters swear by them and I can see why.

I'm not usually very hungry the day after a fast but ravenous on the 2nd day - I don't know how ADFers do it!

greenfig · 30/04/2013 17:37

postmanpatscat can I ask if you are cal counting on your other days? After a great start I seem to be a bit stuck & am thinking I need to be more strict on the other days until I get to target & then hopefully can maintain, as I seem to be doing now Confused I ask as I think we have similar stats. Thanks

peplum41 · 30/04/2013 17:37

Hello , nice day for a change.
welcome new fasters, hope you get the results you're after
slipperynipple I started off calorie counting all strict like as you do, but this month I've decided to experiment by pushing 5:2 to the limits, to see if I can get away with eating whatever I like on non fast days ( is it time we started abbreviating that to NFD?), and still lose weight. I might give it another months trial, but the answer seems to be yes, but very bouncy, and just 2lbs per month. Early days, but happy to try it as not in a rush to lose weight as I've been fat for about 15 years.

swallowedAfly · 30/04/2013 18:11

am catching up and posting at the same time or i forget who i'm talking to.

ELR - yes it sounds incredibly similar to what i'm going through. it is disheartening and i had a day or two when i avoided the thread.

postman - sounds like you had similar thinking to me with starting the total fasts. i think doing them once a week is going to have to be the way forward for me as 5:2 with the 500cals has not been making me lose weight - other than losing and gaining the same weight for weeks now.

fast day here and i've had nothing so far and hit my target of 20,000 steps by walking all the way to work and back, keeping moving whilst there and walking to the garden centre and back this evening for something to do when i was feeling head hungry.

had to go to the shop for something ds wanted with his tea and that was hard. had to spend over £6 to use my card and didn't need anything so bought a bottle of pinotage which is sitting in the kitchen being tempting but must be ignored. i can now do a total fast which would be best so that's the aim. if i cave i want to cave as late as possible so it is easier to stay well under 500.

plan is to get to ds's bedtime and read him a story and settle him then pour myself a bath and relax with a book to use up more time in non eating associated ways. i think keeping busy and active is going to have to be my strategy for dealing with evenings and avoiding the comfort eating.

good luck to fellow fasters today. hope it hasn't proved too hard with lack of sleep betsy Smile
