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!

Ooh, I'm watching for holiday tips too!

peplum41 · 25/03/2013 21:10

Hi madondogs, hope you can get your enthusiasm back. I'm not the most experienced faster, been doing it about the same time as you, but I sense that there is going to be good days and bad. Euphoric yeah this rules fast days and horrid oh I'm starving / freezing days. All in though, what other diet gives you the freedom and flexibility? That's what's needed when you've a long way to go. Keep those doggies rolling, and don't forget to drink plenty and make filling food choices when you can. Can't do smilies when using phone so my posts look boring!

zippiedoo · 25/03/2013 21:15

It's kinda stressing me out...silly really because I know this WOE is fab and it actually works, without having to worry over the traditional diet concepts of constantly counting cals and limiting self to 'specific types of food'.
Just need to know that all will be well while on hols! Smile

peplum41 · 25/03/2013 21:20

Hi zip just enjoy your short break and don't worry about it. Apparently it does your metabolism good. Going anywhere nice?

Madondogs · 25/03/2013 21:26

Thank you fellow fasters! I think I will be ok tomorrow, hopefully this craving for carbs will disappear after today's fast ( roll on bedtime).

I am utterly determined to stick at this as I think it is a brilliant WOE.
I have already begun to change my relationship with food for the better and already feel healthier .

Thanks all, I read this thread everyday and it really helps me.

Keep strong everyone xx

Appelmoes · 25/03/2013 21:31

I had a good fasting day. Didn't eat for 22 hours and then made baked beans with some veg and vegetarian sausages. It was nice, it fills you up.

I walked for more than an hour today and hopefully make it to the gym tomorrow morning (I might also decide to sleep more, it's hard!!!).

But today wasn't so hard for me. Feel better about all!!! Patience is probably important, everyone lost weight so so should I.

zippiedoo · 25/03/2013 21:34

Thanks peplum41, suppose holidays are for de stressing, last thing I need is to be constantly worrying! We're taking the our son to Milton Keynes for his birthday...he's obsessed with Thomas the Tank! Grin

Talkinpeace · 25/03/2013 21:49

HANG ON IN THERE FOLKS

On fast days, or middling days, go for HUGE portions of veggie soups and stews

  • hot
  • filling
  • healthy
Today I did a 24 hour fast and then shared with DH two pots of soup admittedly having a small bevvie now (but I'm not losing weight)

Seriously .... avoid carbs and go for high protein, high vegetables
whole tin of Baked beans, ham and scrambled eggs = 500 calories plus warm full tummy to last through the night

yup this weather is a RIGHT DOWNER
but you can keep going ...

peplum41 · 25/03/2013 21:54

Seezip that's the kind of thing you want to relax and enjoy. Can imagine his face when he sees those trains!! This is a great flexi fit round you and get a healthy attitude to food way of life.

Applemoes what a fasting champion

sweetkitty · 25/03/2013 22:09

First fast day nearly over I'm starving might have a cuppa before bed.

I've had 550 cals which I'm ok about for my first day, it's DHs and I anniversary tomorrow so were having Chinese for dinner (would love a meal out but no babysitters) then fast day Weds.

Itsaboatjack · 25/03/2013 22:16

Evening all. I've also been joining in the trend of having a blow out weekend Blush

This weather is definitely making it tougher, I was just starting to get into the grove of it when we were having our brief glimpse of spring a few weeks back, and now we are plunged back into winter again it's almost doubly hard. Hopefully though if we do get a summer this yet I'll be able to wear a nice sundress without my thighs rubbing together Blush

Fast day been pretty good today, though I did break it earlier than usual, I usually try to go through until dinner but I needed some hot soup about 3pm to warm me up. Another fast tomorrow where I hope to go for 24hrs, will actually be more like 26hrs as I won't get to eat until after I pick dd up from brownies.

Talkinpeace · 25/03/2013 22:19

sweetkitty
do not go to bed starving : have hot drink - milk or bovril or something - otherwise you'll not sleep well

scripsi · 25/03/2013 22:29

If I can't sleep due to the hunger I have one boiled egg sweetkitty
I am wondering if anyone has noticed that they aren't doing the full TDEE on non-fast days? I just started using the MyFitnessPal app and have worked out that I am around the 800 calorie mark on non-fast days, which is a surprise.

Breadandwine · 26/03/2013 03:16

Bssh Great post! Loved your final sentence! Grin

You'll be joining us on the maintaining thread before you know it!

About eating on holidays - as others have said, you should relax and enjoy yourself. But, why not try missing the odd breakfast - or breakfast and lunch if you'd like. Then have a normal dinner - including pud if you want!

If you can throw in a couple of these 'mini-fasts', it'll help you stay on track and you'll feel very virtuous! Smile

On the other hand, if you can't manage to do that - just put 5:2 on hold and take it up when you return. After all, this WOL is just that - for life!

I've just had a vegan fry-up with a glass of wine whilst listening to England hanging on for dear life in NZ. You know those meals when you eat slower and slower, taking smaller and smaller mouthfuls, towards the end? This was just such a meal. Gorgeous! And I'm on my second glass of wine, so even if England lose, I shall feel no pain! Wink

Nice to see the thread continuing in exactly the same positive, friendly, supportive vein as it started - even though the personnel has changed somewhat. Flowers

Here, at least, we're all in this together!

sweetkitty · 26/03/2013 05:52

Morning all I had a cuppa before bed but felt hungry and had quite a bad nights sleep not helped by DS getting up at 5am being sick.

Just about to have some toast.

So does it get easier? Does your body get used to fasting? I'm in awe of some of you doing 24 hour fasts.

swallowedAfly · 26/03/2013 06:25

scales back down a pound but still a pound above my lowest after a fast day. bit disappointing but must be realistic. am thinking i might do another fast today and see if two back to back shakes things up a bit.

morning all.

swallowedAfly · 26/03/2013 06:30

i missed a page!

sweetkitty - yes it gets easier. i find it pretty easy to go all day without food - my challenge is to not overeat once i have broken the fast in the evening.

i'm noticing though that it is always harder for me after a couple of days of eating too many carbs and junk food.

i am not a doctor but from the bits i've read on the effect this woe has i'm wondering if it's to do with insulin - so a couple of days of getting your insulin levels jumping all over the place with sugars/refined carbs means they're still jumpy come the fast day. thoughts anyone?

frenchfancy · 26/03/2013 06:44

scripsi 800 cals on fast days is not enough. You need to have a good difference between fast days and feed days. If you want to lose weight a bit quicker then try adding an extra fast day, but eat more on feed days.

Holiday tips I managed to lose weight on holiday. As B+W said go for 2 or 3 mini fasts - so eat nothing all day but normally in the evening. The other important thing is to keep active. Go for a walk or a run, take the kids swimming and don't stop movibg in the pool, have a boogie. I went to a waterpark. I knew the food would be terrible so I didn't eat. We had a great time and where normally I would watch from the sidelines I ran and swam like a loony like the othersGrin

SerotoninCanEatTomorrow · 26/03/2013 07:38

I am having the bank holiday weekend off - although am going to try 'mini fasts' all weekend if I can. But not gonna limit evening meals (or chocolate!) and that's very empowering. At the end of this week I will be sorting through my clothes and removing those that don't fit anymore - mainly jeans/leggings. And some tops/bras too. Then when I reach goal weight (another stone or so to go) I will start buying clothes - should be a good size 10 by then!

Have just signed up for Race For Life Grin

Northstarmum · 26/03/2013 08:07

Fasting today after a splurge weekend and Monday. So I've a feeling this one is going to be tough but I need it! Normally I'm a daiy weigher but today I'm going to avoid the scales until I've had a chance to reset my system! Good luck other fasters. Btw, I've also lost nearly a stone and no one has mentioned it- but I wore a new dress to work last week (unusual for me) and got loads of compliments which I do think was due to my newly svelte figure as well as the dress Wink - maybe no one liked to ask if I'd lost weight?

ErikNorseman · 26/03/2013 08:11

Scripsi 800 cals on eating days? Did you mean 1800? 800 is far too low and you will end up starving yourself if you are only eating between 500-800 calories a day. You need to eat enough on eat days, why are you eating so little? It's not normal to eat only 800 cals on a day you are eating 'normally' because 800 cals isn't normal for anyone. There must be a reason why you eat so,little. Are you afraid of not losing weight? Or (forgive me for asking) do you have a history of disordered eating? If so, this WOE may not be right for you.

ErikNorseman · 26/03/2013 08:12

Sweet kitty if you are fasting then toast in the morning is the worst thing you can eat. You will be ravenous at lunchtime. If you must have breakfast on fast days then a banana or some porridge would be better.

tracedw · 26/03/2013 08:15

Morning....well done to all fasters yesterday and good luck to everyone fasting today.
The weather this morning in Ireland is clear, sunny and dry, we have yet to see any of the bad conditions you have had in England, since we moved here last year the weather has been nothing but mild (apart from the rain, it rains a lot)
I have glimpsed a new low this morning.....9st 5.6lb.....started at 10 st about 8-9 weeks ago, so only a stone to go, i am only a very tiny framed 5 ft 2 ( with a TDEE of 1500) so 8 st 5 -7lb is comfortable and i have a wardrobe full of size 10's ready and waiting ( i was this weight until 5 yrs ago when i got pregnant with ds3)

holiday tips we had 4 days in a hotel recently, i skipped the usual fry up and had fruit and yoghurt, soup for the pub lunch and had the fish option in the evening at the hotel and no pudding, i also used the hotel gym(never have before ) and long walks on the beach.....drank like a fish thoughWine
I didnt gain.

swallowedAfly · 26/03/2013 08:18

decision made - i am not going to do second fast day in a row and have just eaten a wagon wheel. this from someone who never, never, never eats breakfast. don't know what's going on with me but i'm feeling hunger a lot and this for once felt like physical hunger rather than head hunger and that next to never happens.

fasting tomorrow and friday if i can manage it.

erik i think sweetkitty fasted yesterday - today is an eating day for her if i read it right.

postmanpatseasterbunny · 26/03/2013 08:19

Morning all :)

tracedw v similar to you...started almost 5 weeks ago at 10st 1 and now 9st 5. I had never been over 9st til I was pregnant with DD1 and she's 15 now!

Wish it was mild here! About 2C in London this morning.
