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!

Right! I've had 2 weeks off fasting thanks to this swine of a cold. Sadly I reverted to type in the 2weeks and binged :-( Anyway, I'm back on track today. About to weigh myself so you need to cover your ears now ..,

ellenbrody · 25/03/2013 07:01

Re: spots. I've noticed a much clearer complexion on the 10 weeks I've been doing this. Lots and lots of water and loads of veggies, particularly on fast days, but most other days too.

You always read, in magazines and whatnot, the importance of drinking lots of water, however, it's easy not to appreciate the health benefits until you actually do it. Unfortunate side effect: getting up in the night for the loo!

VivaLeBeaver · 25/03/2013 07:04

Weetabix probably wasn't the best idea.....I just thought it was low calories so good. But I guess similar calories of protein would have filled me up for longer?

Southeastdweller · 25/03/2013 07:31

I'm glad I'm not the only one who overindulged last week!

Doing 4:3 this week in an attempt to lose what I've probably put on.

Good luck this week everyone!

Easter coming up so any ideas to avoid over indulging on chocolate is most welcome.

akarucker · 25/03/2013 07:34

viva the first few fasts I did I ate cereal and fruit. Oh wow was I hungry!! Yep, stay clear of those foods. Protein, veg, soups are all more filling. Also, people often find that the hunger trigger is stronger after the first bit of food, so it may help to delay your first meal on a fast day. Perhaps stretch it to late morning to start with.

Southeastdweller · 25/03/2013 07:36

viva I usually have two boiled eggs for a weekend fast day breakfast with a little salad cream. This fills me up for a good few hours.

SerotoninCanEatTomorrow · 25/03/2013 07:55

I'm back on form again - sorry about the ranty post last night. Had a good 2.5 mile run this morning and am fasting today so I should (hopefully) get the euphoric benefits of the fast as well as the exercise endorphins Smile

Thank you for all the virtual hugs - for a nest of vipers you guys are lovely xx

dottt · 25/03/2013 07:58

May I join please? Three stone to lose always beenOW and failed
and done every other diet. Feel despondent but want to try

BetsyVanBell · 25/03/2013 08:09

Hi dottt Come and join in :) Read the OP and follow the links for lots of hints and tips.

In a nutshell though have 2 days per week where you eat no more than 500cals from one sleep to the next (you can work your way down to this if it's too hard) and the rest of the week you eat normally. If you are unsure what 'normal' is then find out what your tdee is (link above) and work towards eating that.

Exercise really helps too! Especially on a fast day believe it or not.

Average weight loss seems to be about 1lb per week though some people lose nothing initially then 3 weeks in suddenly start, others lose loads at the beginning then slow down so don't be disheartened if you don't see the scales shift right away. Do take waist, hip, arm & thigh measurements though as you may find you get losses here more quickly than the scales!

This is better than a diet as it has loads of health benefits and you don't have to deny yourself the odd treat!

silverbeetle · 25/03/2013 08:14

sidebar hope you feel better soon and all goes OK

Seratonin sometimes life is such a P*sser, hang in there and be strong. Sending ((HUGS))

Benn doing this WOL for 6 weeks now and feel really good despite all the other crap I have going on. Weighed myself this morning and came in at 10st 11.4lb, really pleased as that's after the weekend Grin. This means I have lost 7lbs in 6 weeks. After 3 weeks of really slow loss (no change, 0.2lb off etc), 3lb actually came off this week!
One difference between this week and the previous few weeks is that I didn't count cals on non-fast days but I did reduce the amount of carbs I was eating in meals. For example one spoon of rice rather than two, but more veg/chicken curry or extra spoonful of veg - clearly for me that makes a difference.

Fasting today and hoping I can continue this downward trend, good luck everyone and stay warm - time for Brew here

BetsyVanBell · 25/03/2013 08:15

seratonin [jealous of your run face] I can't find the motivation to run in this weather :( Was going to have a Jillian workout this morning but life has put the kibosh on that. I've been thinking I really must try and motivate myself to exercise later in the day as presently if I can't work out in the morning I mentally think 'well that's that for the day then' which is silly really.

Bramblesinafield · 25/03/2013 08:17

Morning all, newbies and lurkers too. Fasting with the Monday crowd, although major dentist appointment this afternoon so will be making sure I have something hearty before.

Stay warm, all.

silverbeetle · 25/03/2013 08:19

Forgot to add, also measured myself:

Waist -2in
Hips -0.5in (this is my dodgy area)
Thigh R -0.5in
Thigh L -1in
Bust -1.5in (not so good, not particularly well endowed anyway)

Thank goodness for padded bras Smile

BetsyVanBell · 25/03/2013 08:20

Silverbeetle Whoop! Brilliant news, and yes to reducing carbs - think how much better for you that extra veg & lean protein is compared to the filling stodge too :)

Relieved weigh in today - maintained my weight from end of last week despite barely moving and eating lots. It's not my lowest weigh ever or anything but I'm bouncing around a lower weight than I was a week ago so I'm happy with that.

ELR · 25/03/2013 08:23

I am officially p*'..ed off just got weighed and 2.5lbs back to 10st10 my bodies favourite weight!!

Fasting today but really don't feel like it now!! but i know that would make me even more annoyed and disappointed so I will carry on aaaarrggg!!

silverbeetle · 25/03/2013 08:27

BetsyVB being able to maintain your weight is a real accomplishment. It's a nervy experience getting on the scales after a bit over indulgence.
I tend to hold my breath and look with one eye just in case it makes a difference Grin

silverbeetle · 25/03/2013 08:31

ELR I really empathise, that's exactly what happened to me. You will feel better after a fast and back in control. My body seemed to like 11st 1lb for ages, it was so frustrating. Don't be annoyed and have a bad day 10st 10lb is still good Smile

HopAndEggRoll · 25/03/2013 08:56

This is my first week but first fast will be tomorrow (tue and thu best days for me). My food plan for tomorrow is two boiled eggs and an apple for brunch/lunch/as late as I can leave it and ratatouille with some cous cous for dinner. How does that sound?

ELR · 25/03/2013 09:30

beetle thanks for your comment I know you are right! I have been 10st10 for the last ten years, I go on diets ect loose a bit then seem to yo yo up and down back to 10St10lb. It's been my birthday this weekend so really have over indulged so expected it really. Just had a black coffee and now gonna tidy the house like a mad women to burn some calories!!

ELR · 25/03/2013 09:33

hop sounds good but I would only limit cous cous to 20g dry and then try to add some butter beans or other canned beans or better still leave out the cous cous and just go with ratatouille and some canned beans.

akarucker · 25/03/2013 09:38

hop I was also just about to suggest having beans instead of the cous cous. Sounds like a good plan though.

greenfig · 25/03/2013 09:44

Wow things have moved fast since friday! Welcome to all newbies & good luckSmile Have had a happy time reading posts (in bed) as its the hols & everyone is still asleep. I will be interested to see how I find fasting with the children off school, 1st 1 today!
My good news is that the mystery 5lbs that I put on overnight this time last week has gone so I'm back down to previous low & hoping for a new low after todays fast(v excited!) Thanks to the thread for helping me keep the faith. Hope this encourages you ELRSmile
Haven't been able to Jillian as my bad chest has left me too breathless. Attempted it yestrday & after 10mins almost threw up!!
Interesting re weight/height stats I am 5.4 ish started at 10.11 pre 5:2 now 9.5 but still got a way to reduce BF%. I also don't want to lose too much more as am 41 & don't want the haggard look. Also 39" hips that will not get any smaller as that's simply the size of them!! Can def notice reduction in tummy now. The lower 'pouch' that I've had since children (oldest is 11) has goneShock

ElizaCBennett · 25/03/2013 10:09

Morning all. I spent last week in bed with a bug. Basically didn't eat from Sunday at 6 pm till Thursday at 11 am when I had some soup. Drank plenty of water and fruit tea during the week. I lost 5 lb during the week, but this morning 3 lb back on! Now I haven't eaten much at all so am not worried but just goes to show how our body weight fluctuates and leads us to think our hard work has had no effect.

Fast day for me today so let's see what tomorrow brings!

dines · 25/03/2013 10:21

So exercise on fast day helps.. how come on a fast day ? Can anyone explain?

sweetkitty · 25/03/2013 10:21

Morning fellow fastens this is day 2 of fasting or me, day 1 last week was a disaster but I've planned my day, lunch is a weight watchers soup and banana, mid afternoon snack a bit of fruit, dinner will be about 350 cals. Should be slightly over but ok for first day I think. I've got a busy day ahead and painting this evening.
