5:2 Diet Thread: Part Four! Sit down, have a cuppa..

The continuing thread for those of us following either the 5:2 diet or the alternate-day fasting diet. Both are two versions of Intermittent Fasting, which you can read more about here.

The 5:2 diet was featured on Horizon recently, and essentially requires you to fast for 2 non-consecutive days per week. The other 5 days, you can eat what you like. 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, on those days.

Here is a list of the links we've gathered so far about this diet. I hope I haven't left many out, but it was a 40 page thread! This is a good start for anyone, though:

First things first, here is a link to our previous thread, which we've outgrown. Lots of good support and ideas still to be found there. Here is the thread before that..

Here is the link to the BBC article regarding Michael Mosley's findings, which was featured on Horizon.

is a link to the first part of the aforementioned Horizon, subsequent parts of that episode are linked on that page.

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.

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%).")

Important link 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.

And for those already fasting, here is a link to 100 snacks under 100 calories. :)

Another food link, here is a link to the BBC Goof Food site, with a list of low-calorie soups.

We often mention basal metabolic rate (BMR) here. This refers to the amount of energy (calories) a person uses when at rest; so, the basic number of calories a person needs to stay the same weight. This number is often quoted as being 2000 calories for the "average" woman, but of course is different depending on how tall you are, how much you weigh, etc. Here is a calculator which will easily help you to find out what your BMR is.

A BIG THANK YOU to all who have been contributing, btw. Most of us are new to this diet. All of the links above have been posted by others in our previous thread, 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 them all in one post this afternoon. wink

Come join us, and tell us about your experiences with this diet!

I was wondering the same laska.

But then I was also wondering why someone (sorry can't remember who) was eating french fries on a fast day.

I am a gluten junkie but I have realised that cutting gluten out on fast days makes life much much easier. There is 96 calories in a packet of french fries, much more than in my bowl of tomato soup I had yesterday. and for 14 ryvitas I could have a bowl of veg curry. No contest for me.

LizLemon007 · 26/09/2012 09:40

i seem to remember a school friend of mine telling me that each mcDonalds fry had 11 calories. I think she tipped the bag upside down, counted the number of fries and worked it out. And rounded it up. So if you take 9 average sized fries that's a hundred calories.

I wouldn't risk going into mcdonnalds on a fast day though!

mistlethrush · 26/09/2012 09:52

Had a pretty low cal (and low carb) day yesterday and another fast today - currently no problems... However, very busy at work and didn't manage to sort out my DIY hot and sour soup box this morning so have a carton of soup instead. However, at first glance it seems to be remarkably low cal, so I should be able to have that and a salad this evening and still stick to it.

Laska42 · 26/09/2012 09:53

oh just realised it was lookbehind you who helped me out last night not TML .. so thanks LBY Thanks

Thelittlestranger · 26/09/2012 09:55

Talkinpeace, I gave my kids pasta and pesto last week on a fast day...and ended up having cold for lunch the next day it appealed to me so much. But I had added ham, tomatoe, sweet corn and peas...

I've decided to do a fast day today, instead of tomorrow so I can have lunch with my friend tomorrow and dinner with my dad. First time I've only had one feed day in between two fasts, so am experimenting...

Scattergun, I found I could do an extra circuit of weights at the gym when I was fasting, than on a feed day...weird.

Was going to have a chicken Caesar salad for dinner, but am now going to change to a stew I think. Mmmm.

Sorry lizlemon, but the thought of just eating ryvitas all day would make me dread a fast day!!

Laska42 · 26/09/2012 10:03

14 Ryvitas. and not just horrid for a fast day .. I would dread the next day too .. Think of the roughage ..Shock

Ill get me coat..... Smile

On my 6th week doing 5:2 and have lost about 5kg. DH has lost 7kg. We do Monday and Wednesday or Thursday, depending on social arrangements. But we are doing regular exercise, swimming, running etc 4-5 days a week AND not really eating much junk in normal days, sticking to around 2000 cals for me and 2500 for him. Do have a few glasses of wine at the weekend. I'm really surprised how many people still eat stuff like McD's or doughnuts on their regular days, I just don't fancy anything like that now! And my appetite has shrunk a LOT - I used to eat like a pig but unable to.
Stick with it ladies, it DOES get easier!

Satay · 26/09/2012 10:07

Forgot to say, don't weigh daily, once or twice a week only!

Laska42 · 26/09/2012 10:14

Thats brilliant satay well done I've lost about the same now 10lbs (4.6kg) I'm in week five .. do drink wine at weekends, but exercise has gone a bit to pot these last couple of weeks ,( hough i've still lost) I tend to walk and cycle but am intending to get back into running and zumba now .. Back probs stopped me last year but they seem to have cleared up ..

french i'm with you on the soup and veggies ..

mommybunny · 26/09/2012 10:22

Morning all - having a normal day today and will fast tomorrow (not looking forward to it as I'm baking for the Macmillan Coffee Morning at DS's school on Friday Sad). I might have overdone yesterday's "normal" day slightly - went to a cosmetics event with a friend at a department store where we had some prosecco and then went out to dinner, where we each had a glass of Wine. I fancied chips and I had them, but only half a portion, and I only had a tiny starter-sized portion of salmon tartar. I would never have thought to order just a starter and no main before, but there's no reason not to. My friend had steak and chips, telling herself she's going to start on a "food replacement diet" that she got from Boots on Monday Hmm. She knows I'm doing this intermittent fasting, and she has said she's seeing results on me. I'm hoping that will convert her away from a ridiculous food replacement regime that she won't be able to keep up.

As some of you may know, today is Yom Kippur - the Jewish Day of Atonement, when all our Jewish friends fast for 24 hours (not even a sip of water allowed, I believe). With that in mind, I wish you - and them - an easy fast today.

Satay · 26/09/2012 10:22

Thanks Laska, well done to you too! it was great to find this thread. It's my fast day today. Not hungry yet so will be oatmeal for a late breakfast then tonight soup & Ryvita. The miso soup was a good tip by the way, got some stowed in the cupboard now!

GreenEggsAndNichts · 26/09/2012 10:50

Good morning all! Tis a normal day here. I weighed myself this morning and am happy to say I'm down 10 lbs, which is fabulous considering what I've eaten/drank on some of my normal days. Grin

I still have the unshakable cold/chest infection though. booo.

mommy Food replacement diet! And people think we're strange. Wink I liked the comment above about being part of a secret society; it feels that way at times. I rarely tell people what I'm up to, unless I really, really must. (Like the impromptu getogether at a friend's house. She's an excellent cook and had done all kinds of nibbles, but I really didn't want to mess with my fast days that week as I'd planned them around social events at the weekend. I ended up spilling the beans and getting a few Hmm looks, but they were generally supportive. I think!)

Fast day here. Just done my fastest time on a circuit, so fasting has not impaired my athletic performance.

Tom yum soup for lunch with calorie free noodles, then chicken madras with cauliflower rice. Hot drinks of miso, tea and coffee throughout the day.

Could only eat a ryvita that had a thick layer of butter on it, but I could think of quite a few things I'd rather eat first. Fasting has not caused me to change my diet, I don't think...it has made me enjoy the taste of my food though. Yesterday I was almost singing with pleasure while eating pancakes with strawberries and cream cheese. The pleasures of eating....I love food. Smile

Inneedofbrandy · 26/09/2012 10:58

The more I look into this the more I like it. It's exactly what I was complaining about on AIBU there's no oh il never be able to have cheese again or you can only eat protein with nothing else. Need to tell my mum about this!

Laska42 · 26/09/2012 11:00

TML these the shiritaki noodles ? Are they dried or in ea water and if in water do they need to be kept in the fridge ? What brand do you recommend ?.. i'd probably have to get mine mail order (being marooned in the English channel) .. and i've seen them on Amazon .. Where do you get yours please? .. thanksThanks L x

TellMeLater · 26/09/2012 11:12

Laska we get them from Amazon. They come packed in water, as always you need to give them a good rinse before use...

Yam Noodle

Laska42 · 26/09/2012 11:16

Brilliant thanks TML have ordered some and free delivery too..

GreenEggsAndNichts · 26/09/2012 11:16

Brandy yes, I think this sounds like something you should try. I read your post in AIBU but I really didn't want to get stuck in the thread. Too many generalisations flying about. :)

This way of eating has allowed me to finally eat cheese and other items which had previously been banned as I tend to over-indulge in them. Not only can I have them, but I now don't really want to eat too much of them, because I'm simply not as hungry as I was before. It feels very natural.

Laska42 · 26/09/2012 11:25

Oh. yes..... Cheese..... me too this is such a great WOE

Well done on your weight loss greeneggs hope you start to feel better soon that's gone on a bit hasn't it?

I like the secret society bit too. .Whats our password?

We should institute a secret badge to wear too so we can recognise each other ..... suggestions ?? ..

Inneedofbrandy · 26/09/2012 11:33

Yes it sounds a very good way of life and substainable. Not be good for a few weeks then crash off diet and stuff your face with cake!

I known I'm only just joining but secret badge idea should be a cheesy Pom bear!

mistlethrush · 26/09/2012 11:41

It should be a circle with 2/7 coloured differently like a pie chart slice... I was looking for such a pie chart image and came across <a class="break-all" href="http://www.google.co.uk/imgres?start=104&hl=en&sa=X&rlz=1C1GGGE_en-gbGB481GB481&biw=1280&bih=933&tbm=isch&prmd=imvns&tbnid=W6uByJkPCelLhM:&imgrefurl=thefuturebuzz.com/2009/01/26/50-viral-images-part-two/&docid=bSl7CGJF8luHPM&imgurl=thefuturebuzz.com/pics/viral%252520images%252520part%2525202/34piechart.jpg&w=460&h=304&ei=bdtiUP6iEuma1AW3mIHgCA&zoom=1&iact=hc&vpx=176&vpy=135&dur=3&hovh=182&hovw=276&tx=109&ty=104&sig=116753838732282082846&page=4&tbnh=141&tbnw=188&ndsp=36&ved=1t:429,r:6,s:104,i:140" rel="nofollow" target="_blank">this that rather took my fancy though Grin

LizLemon007 · 26/09/2012 11:41

Do tesco do miso soup. Iwas looking in the soup section yesterday and didn't see it. what section?

LizLemon007 · 26/09/2012 11:43

the noodles are 14.90 for 6. (prices vary on amazon i find though) that could be because they're running low because a few people have ordered them, so they put th price up for a few days til they get more in).

GreenEggsAndNichts · 26/09/2012 11:48

Liz I'd be very surprised if they didn't have it at all. Sometimes they put it in the Foreign/Exotic/Whatever section. I often have to go hunting there for black beans for soup. :)
