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 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!

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.

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.

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!

bigchoc no eating out of the jar for me. There was an embargo until I could be sure I wouldn't do anything like that. Not I have a tablespoon in my porridge of an nfd morning. I get the hit without the massive calories.

dumdum I agree with the others that 1200 is too low (though I do know of people with tdee that low but they're very short, are older and don't have weight to lose). Most people on this woe find weight loss works best with the big difference. It messes around with your metabolism so it never settles unlike on normal diets. I never ate too much below tdee and I've lost 5 stone on 5:2 alone so it is more than possible.

For those of you who have been hoop-bruised - try wearing a thicker or double layer of t-shirts or get one of those waist corset-like thingies (or make your own with a thick fabric or towel) as an extra layer of protection against the hoop. You don't have to wear it forever - just till your body gets used to the 'hoopbrasion' and / or your technique improves. I used to get blue-black from my big heavy knobbed Korean hoop but not any more. But we also have to be sensible as there have been cases reported on the internet about people damaging their internal organs through over-hooping.

Itsaboatjack · 31/10/2013 09:09

I'm in so much pain!!! Jillian is evil. I expected my thighs and abs to feel it today, but every tiny little muscle in my body hurts. I feel like I've just been punched all around my torso. Even rolling over in bed hurt so I've not slept well.

I was going to do the DVD again today, but I don't even think I could get into the positions. I'll give it a go though.

NFD here today. Me and dh are going out tonight with friends and I'm sure there will be lots of alcohol so I will have a big late lunch, early dinner to help soak some of it up.

Good luck to all those doing an FD today.

BetsyBell · 31/10/2013 09:11

I've gone right off the idea of hooping this week! Sounds way too dangerous…

Hello UseNorOrnament Welcome! I won't put up any more new starter advice as there's now loads on this page Grin

Southeastdweller. If you're not into lifting weights for exercise then how about some Jillian Michaels workouts? The 30 day shred?

If I could only tell you how fat and wobbly I was before I started doing those workouts!!!

It helps gain muscle but not at the same rate as lifting weights obv, it helps you gain fitness. Reduces cellulite a lot (did for me anyway) and really firms you up. And it's a 20 min workout so it fits into your day easily.

It's a mix of strengths moves and high intensity training so good for sorting fat too.

Only bad news is that you really need to do it 5 to 7 days a week.

I do it 5 days a week sometimes more. It's easy to fit it in.

I honestly cannot rave about it enough.

I hope I have not upset any of the purists or hard core fasters with my whimpy ways of 5:2ing!! I know it's meant to be 500 cals a day and that the longer your fasting window the higher the benefits for your health.

However I still do 16:8 for 5 days a week. I do often find that at 500 cals I can't quite make it but at 600 to 700 I find it easy. It may be cheating a bit but it works. And I increasingly find myself able to manage lower.

lucyintheskywithdinos · 31/10/2013 09:16

Proper FD today. I'm going to my Mum's for the weekend which will involve plenty of food and wine. I'm so very pre-menstrual and craving sugar though, which is why FDs this week are being difficult.

Party tonight, I am going to start cooking some healthy stuff in a minute as my contribution. Veggie mince and tomato stuffed peppers 'carved' to look like Jack o'lanterns. I'll have one plate of whatever I fancy, but no carbs, at the party.

MrsFlorrick · 31/10/2013 09:19

Oh Cookoo. Ouch!! Empty stomach chilli burn. I feel for you!! You poor thing.

How about some gaviscon??

MrsFlorrick · 31/10/2013 09:24

Itsa. Ouch for you too.

You do know the best thing is to have another Jillian session straight away don't you?

And then another tomorrow too.

By day 4 your pain is completely gone. And it diminished each time you do the workout.

It's not what you want to hear but it helps honestly.

Also if it makes you feel better. If I stop for a few days (ie 5 or 6), I am in pain again as soon as I start again.

BsshBossh · 31/10/2013 09:29

Hello fellow Thursday fasters. I have a busy day scheduled today with DD. A group of kids and parents are going to a stately home but they know I fast so no problems not eating infront of them (and the kids will be too busy to notice!). Then shopping with DD afterwards. That should take me to 5pm by which time I'm usually fine. Because of overeating my sedentary TDEE this week (and last week) I'm aiming for a sub-150 cal FD today.

somewherebecomingrain · 31/10/2013 10:06

Hello bash, Lucy, no2be.

Fasting today and finding it fine.

Just shows that when you have a tough FD it doesn't mean it's the end.

mrsflorrick I am similar to you I think - need to cheat and ease but it still works (apart from plateau). I'm totally with you - do what feels right and works.

I constantly have v milky coffee at 50cal a pop - 4 a day - but I'm breast feeding. Will be interested to see if that changes when I stop.

I go madly over my TDEE sometimes I've realised, since doing Mfp. 3,500 is nothing to me. Hard to know what my tdee really is as my activity is all housework, going to shops and park. Not sure if that's lightly or moderately active. Anyway have 2150 as tdee with 0 exercise sessions.

DumDum32 · 31/10/2013 10:44

hey all no idea how to work put TDEE - WOULD SOMEONE KINDLY WORK IT OUT FOR ME :)

HEIGHT: 5' 2"
WEIGHT: 16 STONES
AGE: 32

Just to add I usually end up with having around 1200-1500 cals instead of 1200. I know that still probably doesn't sound a lot but for me it is. I think my stomach is shrinking as I'm feeling less & less hungry day by day.

today is a fasting day so only 500 cals. so far I've had toast & tea for breakfast (been up with little one from early hours so needed a boost). planning to have an apple for lunch & soup for dinner :)

DumDum32 · 31/10/2013 10:48

oh forgother to say because I can't exercise due to medical reasons that is why I thought I should keep calories to a min on NFD's as much as I can I may have got that completely wrong

eatriskier · 31/10/2013 10:50

dumdum assuming you're female here, so sorry if you're not but your TDEE is 2119 at sedentary level. The thing is that there's no point in eating for the sake of it, so if you are happily stuffed at 1500 then that's great but there's also no need to feel deprived day in day out. You will create a massive calorie deficit by just cutting to 500 calories for 2 days a week.

lermontova · 31/10/2013 11:07

Can someone give me a kick up the bum please? I was doing really well at this for a couple of weeks but have now drifted into fasting until late afternoon and then stuffing my face all evening. :(

Sophiste · 31/10/2013 11:13

lermontova sorry to hear you're struggling. Might it suit you better to have a small but filling lunch (e.g. thick veggie soup) so that you don't get to desperation stage by the evening?

One thing I do find helps reinforce the "kitchen is closed" message in the evening is to do a really thorough toothbrush, floss and mouthwash-gargle session. Knowing that I'd have to do that all again if I ate something definitely knocks the head on any cravings.

Anyway, consider yourself kicked up the bum Smile

Sophiste · 31/10/2013 11:14

Not sure "knocks the head on any cravings" makes sense, but you get my drift...

WilsonFrickett · 31/10/2013 12:16

lermon I split my cals in to two meals or I fear I would do this too. Can you try a small, filling lunch, as Sophiste suggests?

What do you eat when you go off track - sweet things, carbs? How about a two-course meal, ie have a soup or something small but filling first, then wait half an hour before having your main meal? Do you forget to drink fluids in the evening (I struggled with this, easy to keep glugging back the water when I'm at my desk but not something I naturally do in the evening)?

Itsaboatjack · 31/10/2013 12:21

I did it MrsF. Well I did Jillian's shred it with weights kettle bell work out. Thought I'd mix it up a bit, or more like I didn't think manage more than 1 burpy, never mind spider planks. I fully expect to be too hungover to do one tomorrow though Grin. But I'll make sure I get straight back into it after.

lermontova I sometimes find myself doing that too. I often find liquid only fasts easier as the hunger doesn't get triggered iykwim. Or maybe try and plan something to do straight after your evening meal so you are distracted from the craving to eat more. The other day I thought I would struggle in the evening as dc are at parents and dh was working so I took myself off to the shops looking at all the lovely smaller size clothes that I'll be able to wear if I stick to it.

dumdum, if you're making good food choices you can easily be full and satisfied on 1200-1500 calories so if that's working for you great. I think the thing is not to feel deprived, so for instance if you're out for coffee or a meal with friends etc don't feel bad about eating or drinking something more calorific every now and then

MrsFlorrick · 31/10/2013 12:41

Well done Itsa!!! Grin Once you've broken the back of it over the first few days it doesn't feel bad after that. It gets easier.

I've done my 6w6p Jillian session and its a FD here so am having a soup of 140cals to break fast from last night. Not very filling this prudential chicken soup thingy. It's going to be a very very long afternoon!!!

whimsicalname · 31/10/2013 12:49

Complete fast fail here: forgot it was meant to be a fd, got up and had 2 lovely pieces of toast, then the toddler's crusts. Transpires I am a bin afterall. That said, I'm hanging after a couple of terrible nights' sleep, I'm still fighting off a cold I feel like I've had for ages and it's Halloween so there will be mucho candy in the house later. I will try and hold back and only eat the good stuff (much more limiting than it sounds!) and go to body pump in a bit.

Good luck to the better fasters!

TheLeastAccomplishedBennetGirl · 31/10/2013 13:42

i'm on FD today, but really struggling

am playing nurse to injured DS1 who has had to move in for the near future, and he eats so much!

i actually spat out some cheese that i cut (extra) as i made his lunch, i totally forgot, but now am going to have some soup to break my fast from 7pm last night

this is my toughest day in 7 weeks Sad

Alibabaandthe40nappies · 31/10/2013 14:11

FD here today.

I am struggling, feel really tired and just want to eat!

I don't normally have lunch on a FD, but I've just had a small plate of carrots, satsuma, cheese, brazil nuts and a smear of peanut butter with a big cup of tea for 200 calories.
Now I just feel tired and want to sleep - if I thought the DSs would let me I would grab 15 minutes on the sofa which might see me through.

MrsF what you said really struck a chord with me. DH has just started a new job and is working longer hours. I'm finding it hard to fast, but I need to make it work.

hollolew2 · 31/10/2013 14:15

FD today I don't find them too bad but I get really cold apart from wrapping up gradually over the day . Thick socks two jumpers etc ( very attractive ) I drink a lot of bouillon and peppermint tea and went for a power walk to get warm does anyone have any tips ?

eatriskier · 31/10/2013 14:22

Dear lord it is cold and my extremities are frozen. Its also turned my hair green. Ok, that was me but I am soooooo cold. First mini fast of the new regime today. Am having one of those short hitting but very intense hunger pang days. Need to convince DH to take me to the local Tesco so I can pick something up to add to my dinner to make it complete. Then I should be able to get through.

hollo I pace around my living room and drink lots of tea. Which is pretty much what you've been doing!

BetsyBell · 31/10/2013 14:52

Well I half thought it might be a fast day today so went down the no breakfast route, but then I took the kids out for lunch so changed my mind! Might skip dinner and tomorrow's breakfast and call it a mini fast though :)
