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!

going to try to stick to 1400 on nfd for a week or 2 and see how I get on.

MazzleDazzle · 03/01/2014 08:14

I'd still consider 650 cals a successful FD dita. Don't be so hard on yourself! 2lb down? Well done you.

A few folk on here suggesting salty drinks on fast days (bouillon, bovril etc) will have to give that a try. My mother bought me a lovely selection of organic teas from The English Tea Shop for Christmas and they are delicious!

BsshBossh · 03/01/2014 08:15

Turkey welcome back!

Well done new fasters, looks like most of you succeeded. Hurrah!

Betsy good loss, woohoo :)

My official Friday morning weigh in today (incidentally first day of TOM too) and 0.2 lb loss. With only 4lbs left to goal, it's coming off sloooooowwwwwwly. Although DH thinks I'm already at "goal" weight and thinks I should now maintain. He might be right. I've gone from 210 lbs to 129 lbs; BMI 36 to BMI 21. I'm happy with how I feel and look at 129 lbs (my goal was 125 lbs).... I'll continue on over the next week or two then review.

BetsyBell · 03/01/2014 08:22

lilyjo use the link in the OP to find out your TDEE and stick to that for non fast days. You have to set MFP to maintenance rather than weight loss. You need to look at your calorie intake over a week rather than each day as MFP doesn't allow for fast days.

It is the fast days that provide the calorie deficit. I can work out your Tdee for you if you prefer - just need your weight, height and age Smile

BetsyBell · 03/01/2014 08:24

I forgot to say hi to Turkey! Woohoo, welcome back Grin

Eatriskier · 03/01/2014 08:27

betsy well done!

dita 650 is fine and 2lb down is pretty normal - some will be water but if you carry on fasting you will find that 2lb won't re-emerge. I don't know if you plan on daily weighing but if so you will notice your weight going back up. This is completely normal.

Actually to anyone who is planning on weighing frequently - pick a time and day of the week and make that your official weigh in day. Don't get disheartened by weight gains on other days, they'll likely be fluid retention and food in your system weight. Compare official weigh ins to see your proper loss.

bssh you've done so fantastically!

Weighed in and maintained after my new years excess. Brilliant result!

frenchfancy · 03/01/2014 08:28

LilyJo on MFP you need to put in that you want to maintain weight rather than lose it. Your loss comes from the 2 fast days not the other 5. If you try and stick to 1200 on NFDs you will find 5:2 very difficult (and quite possibly not very successful)

To change the settings in MFP go to goals, change goals, then change using the guided method. Put in your current weight as both your current and target weight. I tend to then put lightly active, that way if I exercise I can count the cals. Don't forget that as you lose weight you need to change your goals as your calorie needs will go down.

Coveredinweetabix · 03/01/2014 08:32

Yesterday was tough but I made it. It wasn't helped by DS being up several times in the night as I was tempted each time to go downstairs and have a bit of toast. The good news is that I have lost 3lbs of my 12lbs Christmas gain on that one fast alone. I am looking forward to losing the remaining 9lbs as I feel so lumpy at the moment. I'm going to ADF for the next ten days as that will get me back into my pattern of 4:3 with my FDs being Mon, Weds & Fri.
Well done to all of you newbies. Completely one day successfully (and I'd say 650 is fine for your first attempt) just shows you that you can do it.

MazzleDazzle · 03/01/2014 08:39

Bsshbossh that's some loss! You are my hero. My starting weight was nearly the same as you. Early days for me though!

BetsyBell · 03/01/2014 08:57

bssh - have you managed to get back to the gym yet? Post-injury?

I suppose the advantage of going slightly under would be to say that you've got manoeuvre room BUT on the evidence of this holiday I don't think you need it! You've cracked not over-eating even at Christmas.

Grin
BsshBossh · 03/01/2014 08:59

hopeful great SV and NSV.
Mazzle great SV. And eating only when hungry: that counts as a NSV too Mazzle.
dita I'd count 2 lbs as a recordable loss. Well done.
lily set MFP to maintenance.
Covered good loss too.

I was really looking forward to my Friday NFD today, dreaming about what I wanted to eat, planning a good foodie shop. Then TOM started and now I feel bloated and very tired and not in the mood to eat at all. Oh well.

BsshBossh · 03/01/2014 09:00

Betsy no still no exercise except for brisk long walks in the great outdoors. I'm very nervous to resume weight training so I need to overcome this fear...

Coveredinweetabix · 03/01/2014 09:03

Just broken my fast. In doing so, I noticed that the only food we appear to have in is:

Bread (just had two slices of toast for breakfast so don't really want any more)
Yogurts
Milk
One apple
A dozen blueberries
A few potatoes
One leek
Half a swede
Half a tub of clotted cream
The remains of the Xmas cheese board
One mince pie
One fondant fancy
Three biscotti
Several boxes of chocolates
Several bags of crisps & other nibbles
Two boxes of biscuits
and then there's pasta, rice & baked beans (but no tinned soup)

I think it's handy today is a NFD as I can't leave the house.

At the moment, all I can think of for lunch is some sort of mac cheese dish.

Having had groaning cupboards for the past two weeks, it is a relief to have space in them but I wish that there were things which combined to make a better meal!

BetsyBell · 03/01/2014 09:05

I find that I only usually breakfast after a fast day now, if at all.

Just had a sort of omelette of 1 egg, spoon of yogurt, shredded ham, random cheeses, then a load of peppery leaves (rocket, watercress, spinach) plonked on top. Lid on, warm through, slide onto a plate, eat with gusto.

I'm trying to cut down on grains and refined sugar so avoiding bread.

I avoid bread after a fast day anyway - makes me feel a bit peculiar. An indication I should be avoiding it generally… (I used to - spent years as a wheat-free person as it made me ill, slid back into it during pregnancy, didn't feel awful so carried on).

BetsyBell · 03/01/2014 09:10

bssh I can see why you'd be nervous. I guess you just have to build up ultra slowly and be on a strict watch out for any signs of overdoing it.

LilyJoAndMe · 03/01/2014 09:13

Thanks for the help with MFP. I've changed the set up now and I have 1950 cals on maintenance.
That sounds better ! Oof Smile
So now got to plan meals for the day.

LilyJoAndMe · 03/01/2014 09:18

Well done to everybody too. It' s lovely to hear that the hard work is paying of all round.
As for my own weight loss I'm not sure yet. I drank so much and have not eliminated yet so I don't really know.
So far it looks to be a pound . I hope it'll be more though.

lucyintheskywithdinos · 03/01/2014 09:57

betsy the big thing I notice if I have a good run of no grains is that the shape of my belly changes, it suddenly gets a lot flatter.

dita well done! Easing into it worked for me. Six months in now and I'm hardcore!

Done my yoga workout this morning and I haven't broken my fast yet. Little bit hungry. Can't wait for my big-ass lunchtime salad.

Need to find a 50's style dress for a performance. I hate dresses, so it's haaaaaaaard!

LilyJoAndMe · 03/01/2014 10:01

Go for it Lucy Smile

BsshBossh · 03/01/2014 10:13

lucy what's in your big-ass salad?

ImABadGirl · 03/01/2014 10:13

I'm nearly a week into ADF and have jumped on the scales and lost 3 lb, so nearly buckled last night...I had 90 cals left so was mooching and found the remaining quality street, I checked on mfp and 2 sweets were 88 so ate 2 then thought bugger it I'll have the rest too....I then argued with myself and didn't eat the chocolate, valuable lesson learnt don't eat chocolate on a fd cause it won't help you!!

lucyintheskywithdinos · 03/01/2014 10:25

bssh today it will be a huge amount of little gem, cucumber, red onion, cherry tomatoes, carrots and half an avocado squished with a tablespoon of tahini, salt and lime.

I either do a vinaigrette or an avocado-tahini thing. With vinaigrette I top the salad with toasted seeds too. I'm hungry!

MrsFlorrick · 03/01/2014 11:29

Hello everyone Grin

You're all doing outstanding jobs with the fasting. Especially as your kitchen cupboards must still be stuffed with festive junk and Christmas choc!!

FD again here. It eaten yet but I doubt I will make 500 today. I can tell that once I do start eating, it will open the floodgates. Probably a mini fast sort of a day. Grin

Abi01 · 03/01/2014 11:33

Hi all, would like to join you all if I can :)

I have been lurking since thread #1 after watching Michael Mosleys horizon programme. Originally lost 10lbs but then went off backpacking so I stopped and made the most of all the local foods and beer!

Anyhow to cut a long story short I've started again and have been doing 4:3 since beginning of Dec (with a break over xmas) I'm now on my 3rd FD of the week as I fast on Mon, Weds and Fridays. Started at 12st 2lbs and i am now 11st 6lbs. My target weight is about 9st which should take me to a healthy bmi and body fat mass. Im also combining this with the gym and 30 day shred - level 1 day 3 completed this morning!

I think I read in previous threads that a few people do 30+ hour fasts? I eat nothing on my FDs (I just find it easier) i just have green tea and lots of water, so I end up doing around 30-36hr fasts. I'm really keen to start more HIIT and weight lifting as part of the fitness side, so if I'm going to do this should I be eating 500cals on FD or is it still ok for me to do LOFs?

Thank you :)
