The 5:2 Thread number 22! Put down that biscuit - you can eat it tomorrow

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.

NFD = Non fast day

NSV = Non scale victory

Michael Mosley has a 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 tips and links 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. 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 Greeneggsandnichts for putting together all the 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 diet!

Fasting today at work, resisted the plate of shortbread fingers put in front of me and munched my carrot pieces. Did have a gazillion cups of tea though.
Doing omelettes for supper rather than soup - mainly because I've got lots of spinach in the garden to eat and loads and loads of lettuce ....

Planning : absolutely.
In fact planning shopping : which meal am I going to eat that with? is the secret to not having junk in the house to snack on. Except that I graze on slices of cheese!

Southeastdweller · 25/06/2013 16:41

Fasting here too, not the easiest when there's been a box full of biscuits and chocolates 5 feet away from me all day! Thought I'd try to compensate for two days indulgence in Bristol by doing a very low cal fast today. Had nothing but black coffee and water and as my body feels like it's crying out for some nutrients, dinner will be a pile of veg (including sweetcorn Grin) and an apple. Gym now and will busy myself later by wheeling and dealing on Ebay.

itsaboat Where did you get that coconut oil from?

angelabbie · 25/06/2013 16:44

southeast what do you wheel and deal in, sounds very exciting compared to me watching holby!

EagleRiderDirk · 25/06/2013 16:52

I forgot to say when I was out last night, having lost 2.5 stone, people are still like 'oh I couldn't not eat for 2 days' and then talking about how slimming world and weight watchers work for them. Um, so you'd rather restrict everyday than 2 days a week, ok then?

akarucker · 25/06/2013 17:19

ERD I know, I just watch people nibble on their low cal dinner choices, OR 'blow' their diet because otherwise they can't enjoy the evening. Meanwhile, I plan ahead so that I can have what I want when we go out. HA!

frenchfancy · 25/06/2013 17:29

Exactly ERD and I often think to myself - so exactly WHY does our body store all this energy as fat then? It seems to be those with the most reserves who claim not to be able to go long with out eating - funny that!

Mind you when I started I thought the same, the idea of leaving the house without breakfast brought me out in a cold sweat. I was always planning where I would manage to get my next meal, now I don't sweat it - if I skip a meal it is no big deal.

Talkinpeace · 25/06/2013 17:33

Way back on big thread 11 or somewhere, a newcomer commented that she'd not had a ham and cheese sandwich on white bread for so many years, THAT was her treat.
And she could not even finish it!

I find being "good" for two days and relaxing for 5 is an easy payoff for staying at size 8 Grin

EagleRiderDirk · 25/06/2013 17:35

Ha - yeah, I planned ahead. Had a light lunch and made sure I had a load of exercise calories in me. And then I ended up not having as much as I thought and didn't go over TDEE after all.

headintheclouds · 25/06/2013 18:18

Hi all,
saf amazing weight loss ...look after yourself and recover well & enjoy your holiday. I think we've been doing this for about the same length of time and youve lost much more than me ..Im still waiting for the first stone

dotty you are also doing brilliantly

ERD I agree with the planning your fast day..I plan ahead and havent 'failed.' yet on a fast day ( 21 weeks of it) It hasnt made my weight loss any speedier though.

TIP what I would give to be a size 8 !Envy Ive always been 'good' on 2 relaxed on 5... For some us its just not going to happen..Not that im giving up or anything..still plodding on, softly softly catch the monkey ( a very irritatin g expression I know)

dines im a Tuesday / Thursday faster at the moment..Havent eaten yet since 7pm yesterday. My plan for my dinner at 7 is a salmon nicoise salad.
I had this as a gorgeous lunch last week at a country pub and thought I could replicate that on a fast day for dinner. Its rocket ,tomatoes a bit of smoked salmon and green beans as the salad base , topped with a small piece of grilled salmon fillet and a poached egg. I reckon with a 100g salmon fillet and 50g smoked salmon I can keep the dish to 400 calories AND have a small bowl of strawberries for pudding! im salivating at the thought of it...
On a NFD at the pub it had sundried tomatoes ,olives and new potatoes also in the mix!!

Just as an update I upped my exercise 2 weeks ago and recalculated my TDEE down to 1625 , Im hoping for a quicker weight loss .. I also would like to be sub 10 stones for my holiday in 7 weeks..Ive yet to weigh myself since making the change but I do feel smaller.
oops sorry for long waffle-post..

Talkinpeace · 25/06/2013 18:37

headintheclouds
I agree that size 8 is not achievable for those who are not light framed
but size 10 (1970's size 14) certainly is.

Bssh has decided to go for a harder target after maintaining, because once you get slim you start to realise how good you feel and look.

that salad sounds yummy by the way
and yes, exercise - especially if you can do it on a fast day really helps.

Dotty342kids · 25/06/2013 18:51

headintheclouds recalibrating your TDEE sounds like a good plan to me. I did that a couple of weeks ago and stuck to it religiously for a few days and it definitely shifted a pound or two where I'd not moved for a while.
Well done on upping the exercise too - we're right behind you and your holiday plans Grin

Dotty342kids · 25/06/2013 18:52

*recalculating even!!

Itsaboatjack · 25/06/2013 18:57

SouthEast I got it from Holland and Barrett. They've got a few different ones, I got a brand called Tiana.

Prawntoast · 25/06/2013 19:05

FD today, quite easy as very busy at work and didn't have time to think about food. Sneaked a look at the scale this evening and am at my lowest weight (same for last 2 weeks) and have another FD on Thursday before official weigh in on Friday, shall be peed off if I haven't lost something this week!

ERD my MIL whinges about slimming world, which she is currently on without much success but says she couldn't starve for 2 days. She'd much rather be miserable for 7 instead.

akarucker · 25/06/2013 19:28

In a really strange way, I'm missing ADF. Not that I'm going to go back to it, as I do think I burned out, but I'm pining for it a little bit...might be something to do with the massive Spag Bol I had for dinner, and the full feeling of eating too big a portion...Grin

BsshBossh · 25/06/2013 19:28

It's amazing how many people these days fear hunger. When I was a child we had to wait for our main meals. My mum was always saying, "You'll spoil your appetite if you eat that!". Hunger was just something you tolerated. Now we live in a 24/7 grazing culture and no one can even imagine themselves not eating / or eating very little for a few hours. I think us fasters are quite radical actually Grin

BetsyBell · 25/06/2013 19:29

I was just thinking about how much weight I've lost as this feels like normal now. I had to check my start weight as I actually couldn't believe I was 3 and a half stone heavier than I am now. The 13s and the 12s were quickly shed off like winter coats, the 11s took ages and apparently the 10s are taking just as long. But the trend is still downwards.

Like Bsssh I've re-evaluated and realised I can do better - it's not just about weight, it's about making those jiggly bits firmer, about getting fitter and not just accepting a descent into middle age, it's about having a better, healthier future and getting excited about things, not accepting tiredness and slumping. It's also a little bit about being able to wear nice things, not just what I can 'get away with'.

Did I mention I love this WOE? Grin

Dotty342kids · 25/06/2013 19:44

Think you (and the rest of us) may have mentioned that once or twice Betsy Grin

JB30 · 25/06/2013 19:47

Wow Silver you're at my dream weight too. I'm down 9 pounds as of today, lightest I've been in 6 months. Like you Betty self sabotage is always close to me. When I get under 11.7 I'll have to be super vigilant - I also cock up at that stage - 3 years of yo yo'ing would be broken if I break through. Had a day from the pits of hell and was this close (imagine 1mm gap) to going to buy bottle of wine and bumper bar of ch

JB30 · 25/06/2013 19:49

As I was saying b4 I hit the post button prematurely - Chocolate! Settled for mini munch within Mfp limit of 1500.
A kind of nsv - better behaviour Grin
16:8 tomorrow. Hope everyone else's having a good one

JB30 · 25/06/2013 19:51

Sorry! Betsy not Betty - I hate this stupid phone grrr

dines · 25/06/2013 20:05

Hello guys iv completed my fast day under 500 cals for the first time in agers I dont actually thing iv been under 500 cals since I started, always been over. Now having a cup of tea and plan to have an early night.. lookin forward to some normal eating tomorro.

SoTiredAgain · 25/06/2013 20:19

Well done everyone on their fasts.

NFD for me today. Breakfast, lunch, dinner. No snacks. That is a big breakthrough for me. I don't think I have eaten like that since...well I can't actually remember when. Maybe as a child? I know it's only once, but it's huge thing. Usually if I don't have a snack in the morning, then by eleven, eleven thirty all I can think about is food and how hungry I am! Dinner time came and I ate. It was only later that I thought, hang on a minute, I wasn't starving.

On a downer, no exercise for me today, apart from teaching PE to the littlies. I am just too sore from yesterday. Sad

BetsyBell · 25/06/2013 20:20

Oh, I meant to say thank you to lots of you for the nice words earlier Flowers

Bssh I'm so happy to have been released from the auto-grazing culture, not that I did graze constantly but the realisation that it is bad is a huge breakthrough, as is not having to panic about when the next meal would be ff.

No worries JB30 but let's stop the self sabotage eh! You'll be 11.3 before you know it Grin
