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 calculator to help you figure out how many calories you should be eating in a day.
NFD = Non fast day
NSV = Non scale victory
Michael Mosley has a website to accompany his book on the subject. Please go check it out, as he's the whole reason most of us are here!
Lurkers and new starters: please just jump in and post - you'll find a lot of support here and we’re a friendly bunch.
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 the 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!
eatriskier’s thread has some lovely inspiring stories which are worth checking out if you want some motivation to get started or keep going through a plateau. Please add your own too.
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 - link to that 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.
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 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. (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!

Morning! Thursday FD check in for me.

peplum I limit protein on FDs these days (no meat either). But I too need to look into the research more. It's just a recollection from the documentary & book...

ChristmasPudding6 · 02/01/2014 08:12

Morning everyone. Just checking in for a FD today. Started 11pm last night (couldn't help finish off a few shortbread biscuits!!) so it won't be a 24 hour LOF, but as long as I don't go over 500 cals I will be happy. Hoping my weigh in tomorrow will see me round about where I was mid Dec.

Just done day 2 of 30 day squat challenge and my first attempt at JM's 6W6P. Only level one is available on utube so not sure how long I will do it for. Probably at least a week or two. Does anyone know how many levels there are?

Southeastdweller · 02/01/2014 08:19

Morning. Checking in from Starbucks with my coffee as I'm fasting today and will again on Saturday. My wobbly upper thighs are telling me I need to start afresh today after an indulgent six days. I plan to have another coffee at lunchtime then soup for dinner after I've run errands in town.

Lexington Lovely to hear from you again and have you back on board feeling so positive.

Have a good day everyone.

MaryHadALittleLambWithSomeVeg · 02/01/2014 08:28

Quick name change from Christmas pud to something less sugary and more paleo Wink

MaryHadALittleLambWithSomeVeg · 02/01/2014 08:28

Not sure why I always feel I need to have a food related username either!!?!

emmief77 · 02/01/2014 08:31

Yeah need to kick addiction to Special K, had considered their diet (and Slim Fast), but there is no way I could keep it up past a few days, I need real food!

Been reading some of the other threads, especially like recipes and inspirational ...

I am thinking best way to start is to plan my weeks meals, but feeling a bit overwhelmed and daunted at the moment... help!

BetsyBell · 02/01/2014 08:38

Another faster here! I finished eating by 5.30pm so I'm already 15hours in! Liquid only (tea, coffee, bouillon, water) until this evening then 400 calories of fish pie, salad and veg.

Welcome back Lexington. I'm sure you'll get rid of the excess again quick enough but thanks for coming back and acting as a cautionary tale - I put on weight so very easily that if I drop out of this WOE for a while I'm pretty sure the same would happen to me.

Right fasters, we can do this! And remember, those chocolates/cheese/cava will all be there tomorrow Grin

Today we eat clean - no junk, no booze. We need a break from all that - our bodies will thank us for it.

If it's a nice sunny day where you are then get out there and enjoy it - the further away you are from the kitchen the easier it will be!

MaryHadALittleLambWithSomeVeg · 02/01/2014 08:39

emmief I used to be addicted to cereal. Strange thing is that I now barely eat the stuff. It won't be long before you get used to these changes.

For meal planning on FD just focus on something simple. For example tonight I will be having a grilled salmon steak with salad whilst the rest of the family have their salmon with some potatoes or noodles. My second fast day of the week I usually allow myself a ready meal, preferably a curry without the naan or rice as the hot spices put me off having any pudding. It isn't necessarily 'healthy' to use convenience foods instead if making from scratch but its nice not to have to spend too long preparing meals when you are fasting.
On NFDs stick with what you are used to for now and adjust slightly to reduce calories, using less carbs and more veg. Gradually as you stick with the plan and pick up lots of recipe tips from these forums you will get the hang of it. Just start gradually.

MaryHadALittleLambWithSomeVeg · 02/01/2014 08:42

And no snacking as this is where most of the excess calories will be coming from!

emmief77 · 02/01/2014 08:52

Thanks mary

When do you suggest I have my first fast day? I mean, would today be good?! I haven't eaten since evening meal last night but don't have any meals yet for today! - well, I have some mince ready to make lasagne but rest of family can eat that!

positively9something · 02/01/2014 08:53

Morning all well after Christmas I had put on one pound which i was happy with, I weighed myself this morning as I am 20.3.8 ShockShock well today is a definite fast day and I may even go tongue gym for the first time in months! I liked being 9 something and girl I get back there quickly Confused

ditavonteesed · 02/01/2014 08:56

Hi, I have decided to give this woe a go and today is my fiirst fast day. I was thinking of having soup for lunch and tea but not really sure what to have for my breakfast. the last thing I ate was tea yesterday at about 6pm.

ditavonteesed · 02/01/2014 08:57

oh and I drink black coffee is this ok, didnt think about that and have had a cup already.

frenchfancy · 02/01/2014 09:01

Welcome glass if you have been lurking since thread #1 you are practically one of us old timers anyway. Well done for deciding to make a difference, you won't regret it.

I don't often post on the main thread any more, but I still lurk. FD today then I'll weigh in tomorrow to see if I've done any damage (but I don't think it is too bad).

For those who don't know me, I started 5:2 in September 2012, hit target in April 2013 (lost 33lb) and have been pretty much stable ever since. I will fast in one form or another for the rest of my life.

LexingtonBear · 02/01/2014 09:04

Thanks for the welcome back - I feel better having 'admitted' my failings and am very much ready to start again. I was going to have my first fast tomorrow but realised that in the excitement (hmm) of returning to work and creeping out of the house without waking the kids, I'd forgotten to have breakfast, so I might as well start now. Feels positively cathartic to have black tea and water at my desk again. Less so actually starting to do any work..

Good luck to all of today's fasters

BetsyBell · 02/01/2014 09:06

dita - best not to have anything other than tea/coffee or whatever (a splash of mild is ok), the idea is to eat less and less often on fast days if you want the full benefits! If you've got calories left over after your 2 meals maybe have a boiled egg with your supper? It's very filling, surprisingly so.

If you really can't manage missing breakfast then have that egg this morning - maybe scrambled on a bed of spinach and thinly sliced ham? Avoid carbs and grains in the morning, they will make you hungrier.

New starters: when you feel hungry put the kettle on, drink a hot drink and see if you can wait a bit longer to have that first meal.

Have that hot drink somewhere you don't normally eat - sitting at the kitchen table in view of food won't help.

Feeling hungry won't kill you and it comes in waves; you don't get increasingly more hungry.

Keep busy, don't sit around waiting for a designated eating time!

You can eat all those things you currently want tomorrow.

BetsyBell · 02/01/2014 09:08

A splash of milk is fine! (Include the calories in your daily allowance - about 15 to 20 calories per tea/coffee).

lucyintheskywithdinos · 02/01/2014 09:08

Black coffee is great dita just remember to drink enough water as well. I get really thirsty on FDs. A lot of us try not to eat until we really have to on FDs, try skipping breakfast, but make lunch (soup is perfect!) early if you have to?

Right, I'm doing a 36hr liquid only FD to kick off the New Year's fasting. And after this cup of green tea I am going to kettle bell.

EarSlaps · 02/01/2014 09:10

Mary- there are two levels of 6w6p. The first level seems to be mostly building core strength, then L2 works a lot on the obliques and quite a lot of leg work (I guess building leg muscle helps strip fat so you can see a bit more ab definition). I liked L2, it was pretty challenging.

Emmie- I used to have toast and honey every morning, I never do any more. Just get a new habit! Special K is very sugary and will probably make you quite hungry later as it will give a blood sugar high then low. No reason you can't start today, you could have a small portion of the lasagne mince with lots of veg- or make the Hairy Bikers diet lasagne with leeks instead of pasta- in sure there's a recipe online somewhere.

Black coffee is fine dita- plenty here live on it on FDs.

ELR · 02/01/2014 09:11

Morning all, not sure whether to fast today or tomorrow. We are having a family outing today, iceskating and then kids want to have a pizza as the place we are iceskating has a lovely big pizza oven in their restaurant. Just not sure.......We are all a little ill too with chesty coughs.
Welcome to all the new fasters, keep strong drink plenty and remember you can have it tomorrow!

DottiestDoris · 02/01/2014 09:12

Hi all! I'm a newbie too and am desperate to start attacking my post baby weight. I thought about doing the low carb boot camp but not sure I can cook 2 meals each day as need to cater normally for ds1 and dh. Therefore, I reckon the 5.2 will suit me much better. DS2 is 10 weeks old - I am ebf-does anyone think that the 5.2 and bf aren't compatible? Sorry if this has already been discussed

BetsyBell · 02/01/2014 09:19

Welcome dotty - we have had lots of BF on here and no problems with supply! You should have more calories on fast days though - probably best to allow a 1000 calories. If you have problems then best to stop and come back to this when your baby is a bit older.

Remember to keep hydrated everyone - rather than sipping all day try gulping down a big glass of water here and there. And don't ditch the caffeine if you're used to it - tea and coffee are your fast day friends!

emmief77 · 02/01/2014 09:24

Thanks ear, good way of spending my time on my first FD looking up the Hairy Bikers diet lasagne! - would it be too much to go running tonight too? - I already have this arranged with a friend of mine Smile

MaryHadALittleLambWithSomeVeg · 02/01/2014 09:25

emmief if you feel ready then start today by all means. Lots of support on here and looks like lots of us will be fasting with you.

My goodness this thread moves fast. Only just done kids breakfast and the thread had jumped ahead of me!!!

DottiestDoris · 02/01/2014 09:26

Thank you Betsy Smile my dh in particular is very much of the view that I shouldn't even consider a diet while bf and so it is nice to be able to reassure him that it can be done, and have the support from 'people wot know'. Can't wait to start feeling better about myself -and he should benefit too by having a happier wife!
