Fasting / 5:2 diet

Talk about intermittent fasting and 5:2, including what’s worked for others. Mumsnet hasn't checked the qualifications of anyone posting here. You may wish to speak to a medical professional before starting any diet.

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 these threads started!

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:

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.

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!

My parents are 5.2ing so I talk to them about it. But the problem if you mention it to other people is that then if they see you tucking into 'normal' food then you get the eyebrow and 'I thought you were on a diet' type response.

NFD today. Still deciding on breakfast, we are going out for lunch and then casserole for dinner. Yum.

Biscuits people are idiots, ignore.

Alibabaandthe40nappies · 12/10/2013 08:53

somewhere porridge seems to vary from person to person how full it makes them. I find it very filling, my Mum is ravenous an hour after she eats it.

HellesBellesThinksSometimes · 12/10/2013 09:03

I now officially love your dm EatRiskier and I would love to wear one of those jane norman knitted dresses so well done on that. A colleague at work has a few if them and a great body (years of dancing) and I am Envy whenever she wears them.

Dotty342kids · 12/10/2013 09:06

I really wish I liked porridge as it seems like a really good, healthy breakfast option but just can't bring myself to Smile.
Chopped bananas with a good dollop of low fat natural yoghurt is one of my favourite breakfast things. Or a soft boiled egg and "soldiers". Yum!

Still not quite feeling myself after a week of a horrific cold / cough and lots of work stress but am staying away from food now that I've eaten breakfast, for the rest of today, in anticipation of going out with friends to a pub tonight, renowned for its large portions.

Have a good day everyone!

MelanieCheeks · 12/10/2013 09:12

I love porridge - but not on fast days.

I'm doing an 8 mile run later, so I've just had a bowl of porridge with added good-stuff - goji berries, cinnamon, flaxseed, manuka honey and Greek yoghurt.

BetsyBell · 12/10/2013 09:15

I'm choosy about who I talk about 5:2 about definitely. It helps if you've been doing it a while and are slimmer, bouncing with energy and looking fresh faced when you tell people (and only when they've genuinely asked how you've done it!)

My stock response is generally I eat less and move more, which sums it up nicely (and how I lost a bunch before 5:2)

Love your DM eats Grin

Ah the hunger scare mongerers! That's what I've decided to call them. I told v few people I was doing 5:2, initially cause I was scared I'd fail AGAIN at losing weight, I felt like a diet bore too. And now I've had some visible progress, it's funny how they respond, it's like ohhhh, like they're waiting for me to go all anorexic so they can say, see told you starving yourself wasn't the way to go! They'll have a long wait Grin
I'll still be drinking my wine, eating my delicious food and slipping into my jeans while they're fishing through their handbag for the ww calculator!
I get weary with the watching people terrified of letting the slightest hunger pang rise, keeping your metabolism going my arse(sorry, a bit narky this morning, kids killing each other and I want to kill dh just cause)

RippingYarns · 12/10/2013 10:02

I thought it was just people I knew who recoil go horror at the 5:2. The warnings of developing an eating disorder would be laughable if the real causes of EDs weren't so serious.

I've recently started running too, the nasty things I've had said - you'll wreck your knees, is that wise at your weight, stories of people who have heart attacks or get run over while out - I've learnt to turn up my mp3 and run a bit further away from them.

It's all the reasons they use to cover their own fear of change, of being in control of their own lives.

MrsFlorrick · 12/10/2013 10:05

Eatriskier. Grin At your mum. That's really funny.

I don't tell people about 5:2. Most people will go on about starving yourself all the time.

I have a friend doing 5:2 but that's it.

I honestly don't think it matter what diet you're doing. There will always be lots of people around you quick to tell how dangerous it is etc etc etc.

Probably because they are afraid you'll end up slimmer and fitter than them. Wink

When I low carbed everyone kept telling how bad it was for you. Hmm

As if losing body fat when you're overweight is bad for you Hmm

Hence I don't bother talking about it now with most people.

I get the "but you do not need to diet" line ..... well yes I do because otherwise I'd be as fat as you actually Wink

frenchfancy · 12/10/2013 10:17

downstairs I know we are all different, but I find the days when I am physically active, (and I often have days where I am 8 hours on the go non-stop) are much much easier than the days when I am sitting at a desk.

Mornin' all!

I look forward to coming on here each morning and reading all your lovely stories - I've just realised I've been on these threads for over 12 months now, and the same positive, friendly, helpful ethos still prevails!

I'm lucky in that pretty well all my family and friends have been positive about 5:2 and a lot of them are doing it themselves.

dp is still resistant. Really want him to do it as he has 40 inch waist and his father died young of a heart attack.

somewhere show him my excellent blood results after IFing for 12 months.

nobreadisanisland.blogspot.co.uk/2013/08/intermittent-fasting-my-blood-results.html

My 10 year prognosis is that I have a 21.9% chance of getting a heart attack or a stroke. Given that someone of my age is automatically given 20%, I’m quite happy with that. Grin

Thanks for the new thread, BB!

outtolunchagain · 12/10/2013 11:15

NFD today but very sociable , lunch out and then out again this evening , so decided to have good breakfast rather than save myself and binge on pudding.Had a sachet of oat and barley porridge with milk and have just been on excercise bike for 25 mins, only short but I didn't want to miss a day

BetsyBell · 12/10/2013 11:49

downstairs if you really can't manage without having breakfast on Wednesday (though I reckon you can... Wink) then a boiled egg with some wafer thin ham and a bit of raw spinach will see you through for hours - approx

NFD here, you lot made me want porridge! I had it with cinnamon, apples and a teaspoon of almond butter. May be coincidence but I then ran lots faster than I have been!

Off out to cycle the DDs to a birthday party soon.

wrigglebum · 12/10/2013 13:46

Another vote for eggs downstairs. Soft boiled with asparagus to dip is delicious and filling.

frenchfancy · 12/10/2013 13:50

Give it a try downstairs and remember a grumbling tummy never hurt anyone. As long as you are not in pain and are able to function normally. A bit of discomfort will go away if you ignore it.

It's my 52nd birthday today. I've been 5:2ing since January. I've just run a tough 8 mile cross-country race in 1 hr 28 mins (my target was 1:30). My slightly-cheating post-run weight was 132 pounds, down a stone from my starting weight. I have bags of energy, my nails are in the best condition they've ever been, and I'm saving money from not eating so much.

Starving myself, am I?

BetsyBell · 12/10/2013 16:09

Love it Melanie! Happy Birthday, you sound fabulous, fit and full of life!

Have a fantastic day x
