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!

Thanks postman and betsy Flowers, nice to be back.

BsshBossh · 14/10/2013 11:33

Oh God it's too too too cold to fast I'm really struggling today!!!!

Dotty342kids · 14/10/2013 11:37

Home made soup Bssh? Couple of spoons of dahl to keep you going?

Farewelltoarms · 14/10/2013 11:39

God agree not to weigh on monday. Apparently I have put on 6lb over since Friday - (from 9.13 to 10.5) is this even possible? I wasn't even that indulgent, well, not so you'd put on about 5% of your body weight.
Hmmmm can I blame the scales?

Sophiste · 14/10/2013 11:58

Farewelltoarms I am in the "blame the scales" camp. My naughty scales claim that not only have I not lost anything since my first weigh-in (7 September) but apparently I have gained about 3 kilos Shock.

On the NSV side, however, I look and feel slimmer, have had plenty of unsolicited compliments and am now (I discovered on a weekend shopping trip) comfortably into size 12, having been on the large side of 14 when I started. So I shall carry on blithely ignoring the scales.

eatriskier · 14/10/2013 12:07

Yay witchy biscuits are back Halloween Biscuit

I need to get out more.

Planning some lovely homemade tandoori chicken and onion bhajis (baked) for FD dinner. Also planning to make enough so its ready for Thursday too.

farewell when that happens to me its usually to do with not being able to go. That's not happened to you has it?

Talkinpeace · 14/10/2013 13:02

eatriskier
I still haven't figured out how I'm going to maintain
Easy.
You carry on doing exactly what you have been doing, but allow yourself two days a week of relaxing rather than one.
Seriously.
Your TDEE will now be getting low enough that TDEE-10% is a bit of a chore
and if you work on the toning, then your shape will continue to improve even though your weight will not drop.

PoshPaula · 14/10/2013 13:21

I'm getting through today on Cuppasoup and Bovril (am at work) - it's good for COLD fast days.

MissStrawberry · 14/10/2013 14:28

I am eating today, though sensibly and not stuffing my face. Going to MFP calories later. Will fast tomorrow.

lucy - I hope you feel better soon and having your friend there will cheer you up.

somewhere - hang in there. I have gone up by 3lbs so I know how you feel and also DH used to eat in front of me and I would get upset pre 5:2. Now he eats in the kitchen. Ask your DP to do the same.

I just wanted to say thank you to all who replied to my message from thursday about overdoing it after a fast day. I'm sorry I haven't had a chance to come back here since then but I did appreciate the advice and input!

whimsicalname · 14/10/2013 15:59

Gosh, I think there's been 200 posts since I last wrote anything! I completely fell off the wagon at the end of last week, but still lost half a pound which I'm pleased about. Could have been a lot worse. Fasting today though, and wondering how I'll manage for the next few weeks as we have guests and parties for the best part of the next month.

ThinkICan · 14/10/2013 16:12

Old friends on this thread! The sinner returns, tail between her legs! Yes, lost 22 lb from Sep to Xmas last year, plateaued for 3 months, fell off the wagon, regained 12 of the lost pounds. Now BMI 29.6. Should I join a gym so I can make exercise part of my life? But 58 years old, never been to a gym. Only walked or climbed stairs or done some 25 push-ups. Help :(

ThinkICan · 14/10/2013 16:15

I had to scroll thru 10 threads before finding this one. Is there an easier way? Hi Bssh. Hi TiP.

GrippingArms · 14/10/2013 16:25

Think, have you considered the c25k plan?

Week one is running for 1 minute at a time with walks inbetween the runs.

A woman I know about your age has recently lost 5st and now takes part in parkruns. And she isn't last :)

So good I recommended it twice?

Talkinpeace · 14/10/2013 16:37

Hi there ThinkICan

here's a little thought-ette for you

LOSING WEIGHT WITH A DIET

As an adult a person has a pattern of eating ( method z ) that results in them being overweight (at size a )
They go on a diet restricting calories all the time ( method y ) until they get down to "target weight" ( size b ) and then they come "off the diet" and rapidly return eating as per method z and hence size a

But actually "diet" just means "what you eat"
So you need to eat the right amount to stay stable at size b for ever ( method x ).
By chance, if you are starting from size a eating method x you will lose weight.
But because method x is nice : healthy meals, no excessive restriction, it becomes the new normal and you stay at size b for the rest of your life

If you see what I mean

and as for the exercise stuff - not my thang but have a go at the Shred ....

vieenrose · 14/10/2013 16:38

A belated thanks to Betsy for the new thread.
I haven't had much time to visit lately, I will catch up later, but I wanted to share my good news.
On Friday, I reached my goal, which was to weigh in at 58 kg (it was actually 57.7), the weight I was before I became pregnant with DS1. Total loss since Jan: 32 pounds.
I'm going to carry on with 5:2 though, because for one I can't quite believe it after having been overweight for 8 years, and two, I'm still after the health benefits.
Thanks to everybody for your support, keep up the good work fellow fasters

BsshBossh · 14/10/2013 16:51

Hello ThinkICan! Think about it this way, you've only regained 12 out of 22 lbs :) Anyway, welcome back. What about power walking? That was very effective for me when losing pregnancy weight back in the day and very easy on the joints (I have weak knees). Nowadays I powerwalk up an incline at the gym but if you're near hills and stairs then you could do that instead of the gym.

MissStrawberry · 14/10/2013 17:04

Everyone is doing so well Flowers.

I have heard the BMI system is not always good so I was wondering if anyone can advise me where to look to see what my ideal weight for my height is please?

Talkinpeace · 14/10/2013 17:11

MissStrawberry
Have you looked your height for different weights on "cockeyed"?

And actually BMI is great - its the best approximator for healthy body fat that we have.
Its rarely more than half a stone out
with the caveat of - athletes, models, rugby players and the like.
For normal people its a good guide
BUT
the details of frame shape will determine whether you are somebody who is happy at the lower end of the healthy range or the upper.
Very, very, very few people should be above BMI 24 and be healthy

BUT
do not start beating yourself up with 'ideal weight' as much more important is 'ideal size' - that glance in the mirror and smile moment Wink

GrippingArms · 14/10/2013 17:16

i've got a question, probably for the more seasoned 5:2ers

i don't have a problem feeling hungry, if the pangs get to me i have water or do something else to distract me

i leave it as long as i can before i have my first 'meal' which has been full fat plain yoghurt (don't want to sub fat with sugar, my problem is portion size, not 'bad' food iygwim) with blueberries and a teaspoon of honey - 120 cals in all

i've got a vegetable stew with kidney beans for later, which is 200 cals

i've had one cup of coffee with a teaspoon of sugar - 40 cals at most

so, is it best to eat up to the 500cals with a treat/extra food, or eat as little as you can get away with on NFDs?

my TDEE is 2400 btw, if that helps, i am obese

thanks

MrsFlorrick · 14/10/2013 17:21

Miss s. perhaps try body fat calculator? Could work better.

BMI doesn't take muscle or fat into account just weight against height. So you could be muscly and have a relatively high BMI but be extremely fit and healthy because your body fat is low.

Combination of the two would work I think.

If you want to know if you're in good health (more important than weight) then perhaps GP can help with measuring blood pressure and heart rate or even a blood test if necessary.

Who wanted to know about exercise? How about swimming? The shred is fab. Not into running myself. Or get a bike and cycle??

I swim and shred. Well actually I am doing Jillian michaels 6 week 6 pack. I have just started again in L1 for the third time this year.
