The 5:2 thread number 27 - Season of fasts and mellow rumblingness (with apologies to Keats)

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 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:

All our previous threads can be found by browsing through our very own fasting section of the site.

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 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 diet!

Oh and loads of people report good results with IBS on here all the time - so I don't know whether that's just because 5:2ers tend to low carb at least 2 days a week or whether because both ways of eating give your digestion a bit of a break.

Kinky I have IBS (D predominant) and Pernicious Anaemia. If anything now I have problems going, its been ages since I've had an attack and its a nice if weird change. I'm coping so much better with the PA too. I have to supplement my injections with sublinguals, and since starting 5:2 I don't have to take them until later in the cycle and whilst I still crash I don't crash as hard and crash far later than ever before. But I'm not really sure if this is fasting (I had assumed it was) or the natural carb/gluten reduction that happens as a result of this woe and watching what you eat.

Preciousdaisybear · 01/10/2013 16:21

Back after hospital with DS2. Even managed FD not mainlining choccies! Go me yay! Also trying to be good today and staying low-carb (no bread, rice or pots) but was seduced my DS3s malteasers (our pirate 'treasure') Only had 6 though Blush I think FDs will be best at school, but I agree with the other teachers on this thread that some cals are needed to get through the day - especially with the bolshy teenagers I teach... Official weigh in is Friday as that will be one week. Can't wait to see the results. Sausages for tea with chips for the family and veggies for me.

Alibabaandthe40nappies · 01/10/2013 16:49

That's interesting about it helping IBS. DH has suffered for years and his has cleared up almost completely which is a blessing for all of us!

Sophiste · 01/10/2013 17:02

The improvement in IBS symptoms has for me been absolutely amazing. I lost inches in the very first week off my no-longer-distended tummy. (Now just the flab to go!)

RealityHasALiberalBias · 01/10/2013 17:02

Hi everyone,

My partner and I started 5 2 last week, and we're both feeling really positive about it.

We did our third fast day yesterday and haven't had a problem with not eating - psychologically the diet works really well for us.

I am using MFP to watch my calorie intake on other days - keeping it within weight loss calories on 2/3 of the other days, and not counting at all at the weekend.

We both want to lose about a stone and a half (though I might stretch that to two stone if it goes well...). Lost two pounds last week, let's hope it continues!

I've struggled a bit with low mood and energy on two of the three fast days so far (see other thread), but I'm hoping that will pass, as I don't find I have a problem with wanting to give in and eat (even managed to resist leftover chinese takeaway sitting in the fridge yesterday - having that for dinner tonight!).

I find the mumsnet threads really useful for info and motivation - don't have kids myself but this seems to be a forum full of wise people!

NotAsTired · 01/10/2013 17:06

OK, so how many of us actually work in schools? Grin

MissStrawberry · 01/10/2013 17:09

I also have fibromyalgia and often get brain fog so that would be a bonus if it helped those. Nearly fell asleep this aft. Not good.

Preciousdaisybear · 01/10/2013 17:17

They do say that is there were two teachers at opposite sides of Wembley Stadium they would find each other and talk shop! Grin

SchrodingersFanny · 01/10/2013 17:19

I'm a teacher, secondary. I find it much easier to fast on work days as I am so busy. At the moment our new behaviour policy means so many detentions that I don't get chance to eat!

KinkyDorito · 01/10/2013 17:38

Secondary too. I like the idea of fasting through the day, just hope that stomach rumbling doesn't get too loud Blush. Maybe I'll give a hard stare to the nearest child...

KinkyDorito · 01/10/2013 17:40

Miss It's really shitty. I can put up with the pain, but I hate the out-of-it feeling I get and being so tired all of the time.

zombiesheep · 01/10/2013 17:47

FD day tomorrow, it's strangely addictive this fasting business.

However I need to way tone down my eating on NFD's. I'm getting scared that I'll get the mindset of "I'm not eating tomorrow so might as well eat this/another one of those/all of this" how do I get past that? Eaten so much today that I feel sick. Angry

WilsonFrickett · 01/10/2013 18:00

Hellooooo! Do you just jump in and introduce yourself?

I'm on my second week of the 5:2, fasted yesterday, nfd today, then fd tomorrow again. I'm weirdly finding it quite easy, although I do think about food all the time on fds!

Had a quick skim of the thread and it seems a lot of people low-carb or otherwise calorie-restrict on nfd's, I thought the point was you could eat what you want when you weren't fasting? Have I missed something?

BetsyBell · 01/10/2013 18:24

Hello WilsonFricket! Glad you're enjoying it. You need to keep your eating on NFDs to within your TDEE (link in the OP). Lots of us attempt to under-eat say by 10% on week days so we can feast a bit at the weekends Grin

Zombie the easiest way to get out of the habit of overdoing on NFDs is checking you're eating to TDEE for a week or so, until you get an idea of how much food that is. Then you don't need to calorie count anymore.

The low carbing might just be because feel better when they eat less of the stuff. I know I do

OP posts:
KinkyDorito · 01/10/2013 18:25

Wilson fasting is recommended by some of the low carb experts. I've come over here for the support. If you are low carb, your blood sugar is more stable so you don't ever get ravenously hungry. Before low carb, if I was hungry, I'd be ready to kill - shaky, sick, just awful. Now, it's a bit uncomfortable but nothing like that. It makes it easier to fast, but you don't have to be low carb. Also, low carb on your fast day means you get more food for your 500 calories.

Doesn't feel like fasting when eating a mega tuna salad! FD1 complete. If I get hungry later, which is unlikely now I've eaten, I'll have more miso. Not too bad. I'm thinking of Friday for the next one, then get on Monday/Thurs pattern next week.

MissStrawberry · 01/10/2013 18:39

KD - I am not in constant pain, more like it comes out of the blue and for no apparent reason so it is annoying as I did not expect to have any issues yet. I am not that old!

Talkinpeace · 01/10/2013 18:46

Non fast day lunch picture just popped onto my profile - Laska and I each took "no papparazzi" pictures of each other Grin

BetsyBell · 01/10/2013 19:02

Where's your "no pap" pic tip?! Laska's looking fab, and so does the food.

She had a longer drive home than I did : I took hers and she took mine.

BiscuitsAreMyDownfall · 01/10/2013 19:36

eatriskier we have a Tassimo. I don't like tea or coffee, but do like hot chocolate. Thanks for the tip, need to check that out.

This afternoon hasn't gone to plan food wise, but due to a long day yesterday on top of waking up tired I'm just really tired so been compensating by eating. Work is better now though and I think the rest of the week will be better so I can concentrate on fasting and have a few mini fasts now.

Early night for me.

BiscuitsAreMyDownfall · 01/10/2013 19:55

Wilson I don't low carb. DH does the cooking and we all eat together as a family. Carbs are included every night pretty much. Plus pasta is my favourite food ever and I refuse to give it up Grin I do try to watch my calories on the other days apart from Sat when I have a day off and eat like before.

I'm only in my second week and not done too great, but I did lose a pound overall. Also I look at it as I'm just learning and getting to grips with my new lifestyle so not worrying about it too much just yet.

eatriskier · 01/10/2013 20:14

Wilson I don't low carb either, but I have cut them down a lot especially on fast days. I still count on NFDs because I'm trying to lose weight and the idea is to eat normally. If I knew what normal eating was then I wouldn't have gotten obese. But its far more fun seeing what you can ram into your TDEE than it is into a restricted figure.

BsshBossh · 01/10/2013 20:45

Welcome RealityHasALiberalBias (to the thread and to Mumsnet - loads of non-parents on this site).
Welcome WilsonFrickett I don't low carb at all - not even on fast days as carbs don't seem to make me any hungrier than protein. I don't calorie count on non-fast days either and have lost 2 stones (and counting) on 5:2 since February (another 3 stones last year pre-5:2).
Do what feels right for you. If you don't lose as expected then review your calories/carbs.
