5:2 Diet Thread! Number 15! Our quinceañera!

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.

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!

IndianaMoans, sounds like you've got the hang of it ok. As long as your total calorie count for the day is 500 you've got it right. The tea this morning is fine, just remember to count the kcals as part of your 500 if you take milk or sugar. Do drink plenty of fluid during the day, whether that be coffee, teas, water, squashes etc. (just remember to count any calories), because there's a fair bit of water in food so on a fast day you probably need to drink a bit more to compensate.

Also, some have found fruit makes us hungry so we avoid it on a fast day. That's not to say eating an apple is wrong, if it works for you then carry on. Some have found boiling some eggs and keeping them in the fridge for emergency hunger situations can be helpful. Eggs are high in protein so are quite good for heading off hunger, so if you like eggs this could help on future fast days. Hope some of that helps.

NurseEzzzaChapel · 18/03/2013 13:59

Itsaboatjack, I agree completely. I do 4:3 so if I were to to deny myself anything the evening before a fast then fasting would end up affecting 6 out of 7 days of the week, which I find unacceptable, so I usually content myself with a zero kcal fasting period of from whenever I last consumed calories the evening before a fast until lunch time on a fast day, which can work out at anything from 14 to 20 hours depending on how things are going. Now and then I feel up for waiting until dinner but usually the grumpiness wins out and I have to eat. Hunger I can ignore, but grumpiness is not fair on others IMO.

IndianaMoans · 18/03/2013 14:00

nurseezzza thank you, glad I'm starting off on the right track. Pleased that it was ok to have my early morning cuppa. I am tracking everything on mfp, and including absolutely everything I eat or drink. I am so hungry though! Guess it'll get easier with time. I can't eat egg so that's a no go for me but I will pay attention to whether fruit makes me hungrier, could always eat carrot sticks instead!

fancyanother · 18/03/2013 14:06

Hi, Its my DS's 2nd birthday today and I need some advice- It's my usual fast day today, so I've done my usual fast up until now, just eaten 200 calories. I promised my older son we would have a birthday tea for the little one, just the three of us when he got home from school. I'm wondering- shall I forego the cake or would that just be silly?? I was thinking if I have one slice with tea but stick strictly for the rest of the day and do Weds fast as normal, that should be ok. I can't really practically fit in a different fast day this week, as I have a lot of eating out things, apart from today and wednesday

Talkinpeace · 18/03/2013 14:10

Have a little bit of cake and enjoy the day.

fancyanother · 18/03/2013 14:20

Yeah I was thinking I'd probably end up doing that anyway, and I don't want to go completely mad and blow it. I would be better off planning it into the day. Its only my 2nd week on the diet, so just getting used to it!

Daisy1407 · 18/03/2013 14:41

OMG after starting out so good last week im afraid all my effort was undone by the weeeknd....i got on the scales this morning and have put on 2lb BOOOOOOOO!
However i know my problem and its the £1 Easter eggs i just cant stop eating them on a hangover! After the Welsh rugby game we were celebrating!

2lb im hoping will be gone within a few days - im fasting today and im struggling - all ive had is numerous herbal teas - trying not too eat till tea tonight (getting in my 23 hour fast!)

hands always seem dry on a fast day is this odd?

Good luck fellow fasters! x

swallowedAfly · 18/03/2013 14:45

i feel a bit bleurgh and grouchy. i actually left work early. i don't usually get hungry or light headed or mood affected by fasting but feels like i have today. now i think of it it could be that i ate crap yesterday (fake crisps and chocolate).

feeling like writing today off as a fast day. think i'll be annoyed with myself if i do though.

sorry just having a moan really. feeling quite sorry for myself. reality is that food is unlikely to be a magic cure though. i need to think of something else to make me feel better - relaxing not an option as the guy next door seems to be putting nails into every available bit of wall space.

giraffemum · 18/03/2013 14:46

Enjoying a moment of peace, chamomile and honey tea, mumsnet and a warm radiator. Psyching myself up to a very wet school run.

Good luck with rest of day fellow fasters Smile and enjoy the cake fancyanother

giraffemum · 18/03/2013 14:47

Sorry swallowedafly, couldn't have posted at worst time.

Hope your day/mood improves soon

swallowedAfly · 18/03/2013 14:54

thanks - nothing to be sorry for. i'm just moaning!

Daisy1407 · 18/03/2013 14:57

SwallowedAfly - hope you feel better soon!
Everyone gets bad days now and then - You deserve a moan

Have you gone all day so far fasting - your nearly there

Just have something healthy now and see how you feel in an hours time - you may be a bit better x

droopytulip · 18/03/2013 14:59

Right now Im starting to think Im doing something wrong. Just finished week four and finding fast days Ok....sticking to 500 calories. Had a few pig outs over the month but nothing huge and STILL I'm the same weight I started at. I know it can take a bit to kick in but it would be lovely to hear from anyone who had the same experience and if or when any weight loss happened. Or do I need to change something?

Talkinpeace · 18/03/2013 15:04

droopytulip
are you staying within your TDEE most normal days?
as the most common problem has been people actually eating more than they need on the other days and thus not getting a deficitover the week.
also, how much exercise are you doing - as every flight of stairs on a fast day is for the better

and if you are within TDEE and are exercising, you may be one of the people like Mintyy who will get the metabolic benefits without the weight loss.i

artemis17 · 18/03/2013 15:12

droppytulip. Hi dont despair youre not the only one..before this WOE i had never watched what i ate, now im on my 7th week but have only lost 2lbs of the half stone i'd like to lose. I am strict with my 500cals, dont over eat on the other days, exercise 3x a week and avoid junk food, so i think some of us (whether through not having much to lose, having always been a low BMI or just how we are made) just arent going to have a big weight loss, BUT the health aspects will be going on under the skin, so try to keep at it. :)

HotPanda · 18/03/2013 15:12

I was clearly being dramatic earlier. Having taken some paracetamol and chugged a load of water I feel fine now, if a little tired. I think things are worse when you feel ill in the middle of the night and I managed to scare myself.

I think I am going to struggle to eat my TDEE of 2083 calories today, looking at mfp it would work out a "normal" day for me is about 1500. It seems silly to just eat for the sake of it to use up calories but is that what I should be doing?

Can I ask, how are people weighing? I see comments on "Bouncing" and "new lows".
I weighed on Saturday, and fasted on Sunday. I was planning on keeping my weigh ins to the same time on a Saturday morning but will that not work as it would depend on what days I had fasted that week?

droopytulip · 18/03/2013 15:13

Yes I'm logging my food on normal days with MFP, walk daily with my dogs. I don't have loads to lose maybe 10-14lbs but was really hoping this WOE would shift those last bits of wobble. I don't want to reduce my TDEE as I read this could be just as bad as overeating on normal days. I am fasting today and wonder if trying two consecutive days might help. Isaboatjack does this I think......hmmmmm it can't hurt to try, can it?

Dotty342kids · 18/03/2013 15:24

hotpanda, glad to hear you're feeling better!
I think weighing in is entirely up to you. Some people feel better doing it just once a week / fortnight / month so that they don't see the fluctuations that go on and just see the general downwards trend.
Others (like me!) hop on the scales most days and will therefore see the "bouncing" you'll have read about. Eg. might be 11st3 Tues, Weds, Thurs (fast day) then 11st 1 Friday, but then back up to 11st 2 on the Sat, Sun and Monday. If you only weighed in on the Monday you'd only see the drop, not the little increases that can appear / disappear on all the other days!

I just had some really bad news about a friend of mine starting treatment for breast cancer (I had no idea she had it) and my first instinct is to head to the cake tin but I'm trying really hard not to have an emotional food response to it. It's hard though....

ComeTalkToMe · 18/03/2013 15:32

Dotty342kids I'm really sorry to hear that about your friend. Hope she responds well to the treatment. It is hard to change how we're conditioned to think food will give us emotional comfort though isn't it?

I'm on my third week here and fifth fast day. I have lost weight from my initial weigh in but as I'm weighing every day (too much really) and my weight is bouncing about all over the place I don't know exactly how much.

I managed a 24 hour fast last Thursday but broke at about 2pm today and had some salad and 2 slices of chicken. Will still easily be under 500 today but I seem to find it harder to go a long time on a Monday, think the weekend might have stretched my stomach a little! Blush

swallowedAfly · 18/03/2013 15:40

yes fasted all day so far. going to have a marmite drink now and see how i feel half an hour after that.

realised i feel as if i'm pre-menstrual but can't be because it's nowhere near time. maybe coming down with something.

rocketleaf · 18/03/2013 15:41

droopytulip I had the same thing happen and stopped fasting after 5 weeks for about 2 weeks. Back on it again this week though as decided I may have been hasty. I think that for some of us it's just not going to be as dramatic a loss as others but I just keep thinking of the invisible health benefits. Also quite a few people have said I look slimmer/healthier and my skin is definitely better. I think we just have to not be slaves to the scales! Although I have been considering whether I could manage to go to 4:3 for a bit to see if that speeds things up a bit.

Fasting today and it's going ok, had a light lunch at 12 and am now looking forward to my dinner! Had a total splurge on Saturday (would have been ok if it hadn't been for the bread and butter pudding!) But not too bad a day yesterday so hoping it will all balance out. Weighed in today and back up to 11 stone after weighing at 10st 10lb last week. I think i need better scales!

NurseEzzzaChapel thanks for those musings, i thought that illustration you did very interesting.

Laska42 · 18/03/2013 15:59

..Oh heck I know i've been AWOL.. but i've only just noticed this thread and its 648 messages already Shock

well im having a fast day today... the first in ages ..

also I finally replaced the broken scales and pleased to say I'm another pound down.. at 10st now!! that makes 25 lbs I think now since last August

ellenbrody · 18/03/2013 16:15

I think Monday is the busiest day for fasting if this thread is anything to go by!
I've had one tea with milk, a bag of rocket for lunch and a small packet of fruit nuggets (50cals).
Might try a marmite drink in a minute, to tide me over till my innocent pot at 7ish.
I've also allowed for another couple of cuppas, as DH and I can't go through the evening without tea!!

jenniejenjen · 18/03/2013 16:27

I did well yesterday, fasted until dinner at around 8pm.

Had two glasses of red wine and a martini with my food, felt really drunk. Couldn't get to sleep at all, was tossing/turning/feeling really uncomfortable.

Woke up this morning after 3 hours sleep feeling like I'd worked my way through an entire bottle of overproof rum and smoked a thousand fags.

Usually I'm able to handle my booze, but I feel awful! Sad

Has anyone else experienced this?

ErikNorseman · 18/03/2013 16:53

Hi jenniejen
Did you eat? Because if so, then you must have exceeded your 500 cals. If not...well you might have missed the point a bit! It's not advisable to drink on fast days due to wasting your calorie allowance and the fact that it's not a healthy thing to do.
