The 5:2 Diet Thread number 18! Breaking out the summer wardrobe?

GreenEggsAndNichts · 22/04/2013 10:51

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. (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, 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!

Hi everyone - following recommendation in Dr M book to join Netmum for support here I am! So many peeps doing the fasting thing and it's all positive comments . Despite a failed previous attempt I am trying again with support this time from all of you out there - mainly for weight loss but will embrace the health benefits too!!! Fingers crossed here I go ........ cottage cheese and pear for brekkie mmmm

Whitecat · 25/04/2013 11:24

Congrats to all who have dropped a few. Do you think the warmer weather is helping?

I am distinctly average with a one pound loss which is great because it also means I'm now on the 10/11 stone border Grin and all without busting a gut at the gym.
Welcome Bessy you will find loads of support here.

DesperateDietingHousewife · 25/04/2013 11:58

Alotta, I know what you mean-I don't feel as bothered by sugary things now. I AM eating them but probably because it's a novelty to be able to and still lose weight Grin. I am trying to make healthier choices though and from what everyone says, you seem to calm down after a few weeks anyway.

I have noticed that I want to drink more water on eating days and I am actually craving more fruit-unheard of for me!!

Barbie-a quote from the book-"Citrus fruits in general, and tangerines in particular, contain high concentrations of nobiletin, a compound that 'protects from obesity and atheroclerosis'-in lab mice at least. The same group of researchers previously found that grapefruit, rich in a compound called naringenin, encourages the liver to burn fat rather than store it."

It also list some fruits that are low GI/GL such as strawberries (the lowest), apples, oranges, grapes and pineapple-all nice and sweet but won't spike your blood sugar too much.

mrschambers · 25/04/2013 12:19

Yes, I think next week I might try and do an extra day and see what happens. How is anyone else finding doing an extra day?

I'm fasting today and my head is BANGING so trying to drink lots of water.

Did a cheeky weigh in this morning (usually leave it until Friday mornings after my 2nd fast of the week) and I've stayed the same, which is actually a miracle as I've probably had more wine than I should have this week.

postmanpatscat · 25/04/2013 12:45

Well done miffy

Bssh I did a zero fast on Sunday and a normal one yesterday so I might do another next week - probably Monday as we are away for the weekend and I will need it!

First ever post-fast gain for me this morning AND I went to the gym last night so had a net intake

DesperateDietingHousewife · 25/04/2013 13:15

BsshBossh, have just noticed your post, I must have missed it earlier.

Yes, I'm trying for a full 36 hours on just liquids. It's only my fifth fast so I'm not pressurising myself, just seeing if I can do it. If I can't, I'm not going to stress. I'll try it another time.

I'm doing ok so far, I've had one cup of coffee (I have to have 1% milk though-I hope that doesn't count as breaking the fast??) and loads of water. Will probably have some bouillion and maybe an options hot choc later as well as green tea, fruit tea and a load more waterSmile.

It helps being able to post like this on a fasting day! Knowing others have rumbly tummies too....!

Bramblesinafield · 25/04/2013 13:21

Hope those fasting are going ok today. I'm keeping busy, but keep spotting food programmes or pics!

ELR · 25/04/2013 13:23

Hi all just had a cup of tea so technically broken my fast but not with food.
Just been to a Pilates class not sure about it, does anyone do it? How do you find it?
Miffy think we started around the same weight and time. 10st13.5 on 18th feb last Friday weighed 10st3.5 so lost 10lbs all in all. Can't wait to get into the 9's, well done on your new low I'm hoping for that tomorrow!

Dotty342kids · 25/04/2013 13:31

ELR I do pilates once a week. I know, from speaking to others, that Pilates classes vary dramatically. Some are quite hard going and will definitely make muscles ache. Others are more focussed on recovery from injuries and will be gentler and more about correcting bad posture or getting better. It depends what you want, and what that particular class teacher delivers!
I know I have bad posture, I work at a computer most days and for me, I love the gentle stretching and sense that it's an hour a week where everthing gets put back in the right position iykwim! But, I wouldn't do it for my main source of exercise as like to work up a good sweat so do zumba and tennis for that Grin

akarucker · 25/04/2013 13:37

Eeeeeewwww....not a good weigh in this morning. Out for a birthday dinner tonight, so will fast up until then, but will be enjoying the evening! Proper fast tomorrow.

ELR · 25/04/2013 13:53

Hi dotty I'm used to doing yoga and have done body balance too.
The Pilates just seemed abit slow going and easy! £9 a lesson too so not cheap, I've signed up for another 3 so will decide if I like it then. I suffer from tense shoulder, back and neck and also have planter ficitus so thought this would help.
Just had my lunch of red thai chicken curry and a small portion egg noodles 240 calories, then tonight I have steak, green beans and mashed celeriac that's about 220 so with my cups of tea gonna go over by about 25 today.

monster54 · 25/04/2013 14:06

Urrrgggghhh TOTM has arrived....I don't want to weigh in tomorrow....

I feel all fat and bloaty!!! Does anyone else skip weigh in around this time? To make themselves feel better?!?

Itsaboatjack · 25/04/2013 14:15

Boo. I've got chicken pox!

I've been told to quarantine myself so I'm lying on the sofa watching tv getting bored and wanting to eat. Not a fast day today but don't want to start munching, especially as I won't be moving much for a while. Don't know how it will affect my fasting, or even if I should. Dr said eat normally and drink plenty. I keep getting told how its worse to get as an adult and so will be feeling very very ill quite soon, although at the minute I just feel a bit bluegh. Would normally be a fast tomorrow, I'll see how I feel I guess.

Think I need to get a good book.

DesperateDietingHousewife · 25/04/2013 14:38

itsaboatjack Sad poor you.Hope it's a very mild case

FRom reading the last few posts-am I right in thinking that if I have anything other than water, it's not a "complete fast"? If so, am definitely breaking it now, by having a hot chocolate! Will still try for the 36 hours without any solids though.

Dotty342kids · 25/04/2013 14:54

TOTM here too and I've bloated up like mad. Not good. Normally on a fast day I like the feeling of emptiness but today I feel like I've a eaten five course dinner! I feel your pain monster
Eurgh.
itsaboat oh no! Hope you feel better soon.

BsshBossh · 25/04/2013 15:15

Oh no itsaboat! Don't punish yourself - if you want to eat then eat, you can get back on the fasting train when you're better.

Desperate woohoo, another fellow 36 hour faster and only on your 5th fast? My goodness, you are hardcore :-) Don't stress if you don't make the full 36.

DesperateDietingHousewife · 25/04/2013 16:06

Ha! BsshBossh I may not make it-I'm really struggling ATM-had a hot chocolate and that made me feel better for about half an hour. Downing water now but it's just not doing it for me.

Barbie1 · 25/04/2013 16:23

20 hours into my first fast...not feeling too bad

BsshBossh · 25/04/2013 16:33

Desperate it took me 23 fasts to achieve a zero cal 36 hour one so your effort is commendable. You'll build up to it if it's what you want. I "mastered" 24 hour fasts first :)

ceebeegeebies · 25/04/2013 16:58

Aaah was doing so well today on my fast but just caved and had a mini bar of dairy milk...only 70 cals but I really didn't need it and should have had an apple instead!! Less soup for me for tea Sad

Quick question...my friend is doing this diet aswell, she has bought a book so has read up on it more than I have. Anyway she is saying that on non-fast days I should be following Slimming World type eating - is that true?? I have always taken it that I can pretty much eat what I want on those days as long as I stay within my TDEE which is the attraction of the diet. If I wanted to eat SW way then I would do the SW diet Hmm am I missing something??

DesperateDietingHousewife · 25/04/2013 17:26

Just caved and had two "Tuc" biscuits. I started to get food out for dinnertime for DS and DH and the temptation was too much. Well, I lasted 19 and a half hours without any solid food, so it's a start!! BsshBossh, maybe I was being a tad ambitious!

I'll have a meal shortly but I definitely find it easier going without food all day and saving most of the calories for an evening meal, so I'll keep trying to go longer.

Well done Barbie on your first fasting day!

frenchfancy · 25/04/2013 17:32

ceebee You are right and not your friend. Say within your TDEE on feed days (or at least on average over the 5 feed days) and leave the calorie restriction to your fast days) Otherwise it isn't sustainable, it would be like a normal diet but worse.

Barbie1 · 25/04/2013 17:32

I'm half tempted just to go until breakfast tomorrow Shock but then a 36 hour total fast is a tiny bit silly for my first fast...non?

I'm slightly worried about eating my 500 cals, because ill have to have some carbs with my protein (due to this bloody fussiness)

itaboatjack sorry to hear about the pox, I know if I'm unwell I don't want to eat anyway, hope its a very mild case and you are much better soon.

ceebeegeebies · 25/04/2013 17:47

French - thanks for confirming what I thought. I tried to explain that if you are still strictly watching what you are eating on non-fast days then there is no point in putting yourself through the misery if fasting days but she didn't get my point!

Dotty342kids · 25/04/2013 18:01

Despite having made a lovely looking and smelling mexican chicken thing for our dinner I'm seriously contemplating not eating it as can't imagine it's going to help today's hideous bloatedness. Might just let DH have his portion and I can freeze mine for another fast day. Hmm.
