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!

Yup, alcohol too!

swallowedAfly · 14/04/2013 09:57

oh blimey! no alcohol.

ok i'm in. are we starting tomorrow?

postmanpatscat · 14/04/2013 10:02

bssh I think I'm the only one here who is mad enough to do 36 hour fasts. I've done it twice and managed easily, and lost 2lbs overnight each time and regained a very small proportion of that over the next few days. Generally speaking it seems to boost weight loss as well as giving your body a break. I might now do one in four fasts like that but no more.

As for the sugar addiction, I was coming out of the gym and buying sweets and chocolate every time (had to spend £5 in Asda for free parking as the gym is right next door). In Feb half term I went to the dentist and found I had damaged my teeth so much that I needed a crown and narrowly avoided a root canal. I started 5:2 the next day! I have massively cut down on sugary foods. I can still picture the image in the mirror when the dentist showed me what was left of two of my teeth after all the decay had been drilled away. there were just stumps left and my mouth was full of blood. It has put me off sugar for life!

Dawndonna · 14/04/2013 10:06

How do you do your 36 hours. I thought that's what I was doing. I stop eating around 8 on Wednesday. I have my 500 calories on Thursday (apple at lunch, 400 calorie meal between six and eight) and then nothing until ten or eleven on Friday. I am losing. Is that right?

swallowedAfly · 14/04/2013 10:07

ok - gin has no sugar so if i get desperate i can have a neat gin with ice.

so let's think this out - obviously no biscuits, chocolate, sweets, puddings etc etc. i can't cut out ALL sugar though for example i eat baked beans. are we talking about trying to cut out all sources of sugar? can't be i guess as all veg have sugar in too.

postmanpatscat · 14/04/2013 10:14

dawn I meant 36 hours without food, sorry that's not clear. Many here go 20+ hours without food and then have an evening meal on their fast day. 36 means skipping that too and then having breakfast.

BetsyVanBell · 14/04/2013 10:16

ELR Yes a bit of orange juice would be ok as it's a must with your supplement - better if you squeeze a fresh one!

Dotty I've never been able to cut down - unless I've done 2 weeks of cold turkey first! I don't eat a huge quantity of sugar but once I'm at the point of foraging around the cupboards for something sweet immediately after eating a perfectly lovely meal - that's when I know the addiction is back and I must STOP!

Saf I've decided to be stricter with myself than usual - but if not having any booze is worrying you then that's probably a good reason to have a break from it Wink

I'm starting today.

Dawndonna · 14/04/2013 10:16

Ahh! Now that I don't think I could manage. I lost 4lbs this week, so I'm happy with the way things are going.

Breadandwine · 14/04/2013 10:17

The change for me with my chocolate addiction came when I realised that part of a piece of chocolate would deliver the same flavour hit as the whole piece.

My solution was to cut each square of chocolate into smaller and smaller pieces - as many as 8 sometimes! Then I started eating sultanas along with the chocolate, so I would line up each tiny piece of chocolate with a sultana and eat them together, very slowly. I recorded how long a bar of chocolate lasted, then tried to beat my record. It's a bit obsessive, I know, but it worked for me.

I reduced my wine consumption similarly - I realised one day that half of the glass of wine I was having with my meal had disappeared without it registering. So next time I halved the amount of wine and made sure I relished each sip.

I make my own red wine, and looking at my records, I'm now making half the amount each year that I made a couple of years ago - 10 gallons instead of 20! [hic]

Smile
BetsyVanBell · 14/04/2013 10:30

Saf - I'm thinking more on the lines of processed sugar and personally I'll be avoiding baked beans. Veg is fine, fruits ok in moderation, except dates! (I mention in particular this as I've become a bit hooked on dates and they are ludicrously sweet and sugary - connection?!)

For me I'm thinking a break from white flour goods and potatoes too as they're broken down into sugar very quickly. I'm only planning on being this strict for a couple of weeks but I will continue to try and avoid the obvious shop bought cakes, biscuits snack bars and chocolate for longer.

Bit of an extreme method Patscat! Good to hear you've kicked the post-gym snack habit though!

swallowedAfly · 14/04/2013 10:36

i'm thinking all obvious sources like choc, biscuits etc. i already only drink water and black coffee and alcohol so the alcohol is all that has to change there. i'm going to leave beans in there and i eat very little bread - like once a week or something so that's not an issue. no cereal i guess.

think i will take it as an opportunity to up my protein too.

i'll start tomorrow as i have a family lunch this afternoon and will want to have a glass or two of wine plus tomorrow is the big back to work and routines day so a good time to start something new.

swallowedAfly · 14/04/2013 10:42

i'm getting nervous now! Shock Grin

BetsyVanBell · 14/04/2013 10:43

Sounds good saf - I've put a splash of water into my black coffee as per your recommendation some threads back and you're right, it works a treat. I'd got a bit addicted to the sweetness of the milk after drinking lots of delicious cafe au lait and chocolate chaud on holiday. I'm ready to stop now though.

B&W I'm fine without chocolate, it's the sugar that hooks me in...

BsshBossh · 14/04/2013 10:52

postmanpatscat thanks. I think I will try a 36 hour fast this week. I just need to work out the ideal day as I've just started a weight lifting programme so need to be careful I have enough fuel in my system for those days.

ELR · 14/04/2013 11:37

Ok should be able to do this. Good news about the Gin saf!
I don't drink fizzy or squash or have sugar in tea. Have 75ml of fresh orange with iron supplement on non fasting days.
Cereal wise I sometimes have bran flakes or rude health early bird musilie but usually I eat porridge and never add sugar usually have some berries or grated apple to sweeten it.
Don't eat crisps or white carb products apart from occasional fresh pasta and have potato about 1 or 2 times a month.
Can easily live without chocolate as dont eat that much as get migraine my downfall will be cakes. I love to bake, usually at least twice per week so that will be my challenge.
I also love fruit so will reduce my intake. Alcohol will not be an issue!!

akarucker · 14/04/2013 11:41

bvb I just watched the link you posted, The Bitter Truth. What an eye opener that is!!

Yes, I will do two weeks of cold turkey of cutting out as much of the refined sugar as is practical. That is, chocolate, sweets, cakes, biscuits, puddings etc. I'm still going to allow the sugar that crops up in beans, bread, etc. At the end of the two weeks, I'll see if it's made any difference to my cravings. Today is a fast day, so no time like the present....

Oh, I wish I'd eaten more chocolate yesterday.....too late now!!

Thank you so much for your support on here everyone. I was really thinking this morning that this woe maybe wasn't suited to me after all, but I can see now that it is, it's just another issue I have to overcome. I can, and will, conquer it!!!!

ELR · 14/04/2013 11:41

question to all has anyone experienced an increase or decrease in sex drive on this diet?

virginposter · 14/04/2013 11:46

Good luck to all you guys doing the no sugar diet. I'd like to join in but I'm at my sister's putting in a new kitchen (chaos) and it's all I can manage to keep up with my fasts for two weeks!!

Last year I had a major problem with yeast which gave me terrible rashes and digestive problems and so I was advised to go on a yeast and sugar free diet as yeast thrive on sugar. I cut out all obvious ones (bread) plus the added ones like in baked beans etc but also I cut out fruit, milk and cheese because of their sugars and I did this for 4 months to try to erradicate all yeast from my system. It was a bit hard at first but very soon I found that it was doable and like this woe it got easier and easier as time went by. I too love all the sugar rich things including choc and dates and cakes etc but I did it and felt so much better for it (lost my first half a stone), then saw the Horizon prog and carried on from there.

I slowly included sugar back into my diet and mainly I manage to control it whilst at home but I've been picking at biscuits and all manner of 'bad' things whilst away (stress of doing this kitchen) and have found that I've now got a liking for it again - doh! But I think I'll follow your examples and try cutting it out for a while once I go home to get some control. I find that once I have control I allow myself only so much each week so that it (hipefully) doesn't get out of control.

Anyway, sorry for long post, what I'm trying to say is go for it, you can do it Smile

akarucker · 14/04/2013 11:46

Oh, and I will also go back to ADF for the two weeks, so as not to lose any momentum, and track my eat days on MFP for two weeks to see if I keep within TDEE when the sugar is out.

swallowedAfly · 14/04/2013 11:53

no worries aka - just hope we can help you crack it though a bit stunned that it has ended up with me quitting sugar for a fortnight Confused Grin

sugar is really how i got into this mess. probably said this before but i completely gave up alcohol for 7 months. once i did instead of the relatively small amount of alcohol i was sipping over an evening most evenings i started having sweet stuff instead. when you quit drinking you often find you crave sugar because you're missing the sugar in alcohol. i piled on weight over those months and despite feeling good from not drinking i wasn't feeling good from being chock full of refined sugar and crap and feeling fat and bloated all the time.

i think i will actually start today too [need a scared face]

swallowedAfly · 14/04/2013 11:54

might make today a mini/proper fast too. not sure which yet. will do what i did last week at sunday dinner and not have the meat or yorkshire but a good full plate of veg and three roast potatoes. last week it filled me up nicely and i managed not to eat for the rest of the day. i will see if it works this week.

tomorrowweeat · 14/04/2013 13:11

OK I'm joining in too :) Anyone know of a good sugar free recipe book? All the ones I've seen are very American.

bugsyburge · 14/04/2013 13:34

can I join the no sugar fortnight?

BetsyVanBell · 14/04/2013 13:43

Tomorrowweeat I just cook savoury stuff and don't try and attempt to mollify my system with sugar replacements! You could look at low carb recipes as that's essentially what we're doing isn't it?

I am impromptu fasting today, busy day and warm and sunny here so easy peasy! Need some more fluids though.

aka Smile

I do love this forum Flowers

BetsyVanBell · 14/04/2013 13:45

bugsy Yes please! The more the merrier Grin apart from the bits where we're all really grumpy and desperate for cake that is
