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!

ps, again, my goals are fairly modest. My waist is 29" and I would be delighted delighted if I could get it down to 27". Haven't had that since before two kids. Although Ido not weigh more.

Laska42 · 25/09/2012 13:00

My day's turning into a fast day ... feeling really up for it now..

LizLemon007 · 25/09/2012 13:01

My fitness pal is great for calculating calories. And no matter how obscure the item, even a superquinn sausage only available in ireland, some bod will have got there before you and entered in the calories!!

HOWEVER, I don't want to exist on 1300 cals a day. I feel that as I'm not overweight I shouldn't have to punish myself like that every day indefinitely. So, i use it but loosely. I eat about 1600-1800 cals a day and exercise as well but I don't 'eat back' the calories as they say.

I feel very differently about fasting (500 cals) a day twice a week. That just seems so much more do-able.

worldcitizen · 25/09/2012 13:17

Thanks Laska it is. I will take this to heart. Smile

TellMeLater · 25/09/2012 13:51

Newbies there's no need to feel anxious about fasting, it's something many of us have no experience of and we all go through our own journeys. Some will find not eating easier than others, some will lose more than others, some are focused on health benefits and some weightloss, but none of this has to stop you from trying - you won't know what you can do till you try. From a personal perspective by beginning of week 4 - I'd had enough and I wanted to eat and I did but come week 5 I was ready to fast again, I'm on week 8 now and after losing nothing for the first 7 weeks everything has fallen off in one week - no one has diets sussed, no one has all the answers, it's just a journey we are all sharing together, jump on board and if it doesn't suit get off for a while and maybe try later.

mommybunny completely agree, trying too many things at once can be completely overwhelming and it's all too easy to make yourself feel like a failure when it all goes wrong, and feeling bad about yourself is no help to anyone.

kiwigirl42 · 25/09/2012 14:36

Hello Smile, this thread is useful, thx.
I've just done my third fast day yesterday and god I was starving all day! So I just ate fruit but about 4 helpings - punnet of blackberries (sweet baby jesus they were sour though), punnet of rasps, half a watermelon, strawberrries. I only ate fruit last fast day as well and really like doing it. You can eat quite a lot for 500 cals and it makes me feel smug as I don't usually eat that much Grin I don't know why as I do love fruit. It just the hassle of getting it all in the house I think (I'm housebound a lot and DH usually shops so I have to spell it out for him what I want. But he is getting a lot better fast!)
Of course today I'm not hungry at all. grr.

My jeans are already looser - I got some just washed ones and didn't have to lie on the bed with a coat hanger lol.
I've piled on the weight due to medication and are really hoping this will do the trick

mommybunny · 25/09/2012 14:41

Tip to feasters-after-a-day-of-fasting: don't go to a restaurant for lunch! I find after a day of fasting that I am ravenous by lunchtime, regardless of what I've had for breakfast, and if I have to wait (like I did today) I get very Angry indeed! (A little tipsy too if all I have to keep me going till said lunch arrives is a glass of Wine. Hic!)

GreenEggsAndNichts · 25/09/2012 14:42

worldcitizen You haven't made a bad impression. :) I was merely giving you my feedback after having read all of your posts. I only know how I would react to that, and I would probably not be able to sustain starting a no cake, no pie, no sweet regime in addition to the fasting, all at once.

I realise a few people on this thread are doing low carb as well as this WOE. If you think that is going to be easy for you to sustain in the long term, then by all means, go for it. I just think (as I believe mommybunny mentioned earlier) it's possible to get psyched up and want to do it ALL at once, when in reality, we're just doing one thing at a time. And for this diet, that one thing is to eat under 500 calories for at least 2 days a week.

The rest of it might come naturally, if you want it to. But imo, there's really no reason to put off giving it a try. :)

Laska42 · 25/09/2012 14:43

right ...just had my second (and last meal) of the day ,, Veg Curry 'soup'.. Anyone spotting a trend here? Smile

Just Brew till tomorrow now.. Good luck all other fasters .

LizLemon007 · 25/09/2012 14:44

If I carry on as normal otherwise, eg, on non fast days I eat healthily between 1,600 & 1,700 cals plus jillian workouts, how long 'til I might notice myself a bit thinner? would even two fast days be enough?? I am going to do the first fast day thurs and second monday (because that suits me......)

mistlethrush · 25/09/2012 14:46

Is there any reason for not going to 3 fast days in a first week or would that be overdoing it? Didn't have any issues on fast yesterday - had smaller breakfast today than normal and didn't feel hungry - similarly not starving for lunch either...

I'm trying to go low carb too as I'm sure its better for me - particularly if I give up the bread/pasta side (ie wheat free) and eat what carbs I do have as wholegrain rice or sweetpotato

worldcitizen · 25/09/2012 14:47

Hey GreenEggs thanks. I do understand though. I do not know what came over me to stop this, it's something I wanted to do for a long time and tried and failed etc. but then I moved house and it all just happened from one day to another.
The low carb thing really makes me feel wonderful, and I wouldn't mind cakes and pies and chocolate and I will keep eating eat on feast days, now where so many of you are saying it is totally okay and does not in any way mess up with losing weight. I simply couldn't imagine for this to possible Grin

Laska42 · 25/09/2012 14:51

kiwigirl not sure if i've seem you posting here before , if not, then welcome, if you have, then hello just from me ( who hasn't seen you posing here before!!).

Good luck with this WOE

TalkinPeace2 · 25/09/2012 14:53

There is a thread in AIBU that may be pulling in some new converts .....

mistle
start light and get heavier as you get used to it. You'll be doing this for the rest of your life, its not just a weight loss thing, its a way of looking at life

mistlethrush · 25/09/2012 14:58

Talkin - I know.. but I need to shift 4st that's been hanging around and not moving on 1000 - 1200 cals low carbing... I've always felt fine doing similar in the past, and yesterday wasn't an issue for me at all...

GreenEggsAndNichts · 25/09/2012 14:58

worldcitizen good, I definitely wasn't trying to discourage you from low carbing. I can't keep it up in the long term myself, but I know others can.

I'm merely focusing on this WOE, as it's what this thread is about. And saying that I'm not sure I, personally, would embark on too many things at once. As most others have said, though, it's up to the individual. We are all approaching this our own way.

Whatever works for you :) Good luck!

mommybunny · 25/09/2012 14:59

Liz, it's impossible to say how long till you might see yourself thinner, no matter what you do. You've already said you don't have much weight, if any, to lose. If on "normal" days you are generally eating between 1,600 and 1,700 calories and doing Jillian DVDs, I would suspect you wouldn't have needed the 5:2 plan to begin with. But if you don't do that "normally" already, as I've said before, I think you might be biting off more than you can chew, so to speak, if you attempt all that at once. It is so tempting to want to channel all that initial enthusiasm into thinking of all the ways you can lose weight, on the theory that if one way (5:2) will get you there, 3 ways (5:2, plus low-cal on non-fast days, plus lots of exercise) will get you there quicker. But I believe the vast majority of people who do that will crash and burn quickly, beating themselves up that they failed YET AGAIN.

Fasting Mondays and Thursdays (with no worries about what I get up to in the interim!) works for me - it lets me completely enjoy my weekends, when I love to potter around the kitchen. And on Sundays to the extent I have overdone things I can feel that "come Monday, it will be alright" (with apologies to Jimmy Buffett...).

TalkinPeace2 · 25/09/2012 15:00

But what you have done in the past has not worked.
If you put the weight back on you had not properly trained your system to the correct way.
So that is why its important to walk before you run.
Honest.

Nenufar · 25/09/2012 15:01

Hello,

I have been doing 3 days of fasting (Mon, Wed, Fri) per week for the last 6 weeks. I have lost just over 4 kilos (around 10 pounds). In the last couple of weeks on my fasting days I just seem to run out of energy. Literally my body just seems to feel like it's shutting down. Yesterday afternoon/evening all I could do was lie on the bed and read (fortunately my dh was at home so I could).

Then on my eating days I often feel uncomfortably full and like I don't really enjoy my food. It's almost like I am past the point of hunger.

I do do a lot of exercise (run 30 miles a week) which I do on my eating days, I wonder if this is making me feel worse on my fasting days? Any advice?

GreenEggsAndNichts · 25/09/2012 15:01

Liz I'm not sure anyone can answer that, we're all so different, and we lose at different rates. You have less to lose than I do, for example, so my results won't really compare well. I noticed results (off the scale, had weight results immediately) within 2 weeks or so. I'm also doing 4:3, not 5:2, as I've got some goals in mind and would like to reach them in the time I have. I'll move down to 5:2 at some point. maybe!

Low carbing to me means really getting rid of all the bad sorts of carbs...would like to stick to organic stuff and whole grains, legumes, vegetables, potatoes and rice as carb choices.
Also don't mind cakes and pies occasionally and on feast days, but want to stay away from the shop and bakery bought ones as there is so much stuff in there and not the general normal ingredients.
If my friend bakes an apple pie or makes some sort of chocolate cake and there are say 5-6 wholesome ingredients in there including normal cane sugar, it is all fine...so tasty and so filling too, but when I get all this other stuff then I have all of the sudden massive cravings and always feel hungry and un-fulfilled....

GreenEggsAndNichts · 25/09/2012 15:06

Nenu well done! You're doing what I'm doing (cough, except I'm not running Grin) and we've had similar results.

I haven't had the tiredness thing, though, so maybe someone else can help. Do you do any exercise on your fasting days? I find moderate exercise keeps me going on fast days. My moderate I mean, I walk at a brisk pace for an hour or so every day, in addition to my usual routine. I don't do cardio on those days, but I know a couple of people on this thread do, so maybe they have suggestions.

LapsedPacifist · 25/09/2012 15:09

Hi everyone, just started my 3rd fast day today and would like some advice please. Is anyone here doing ADF? My BMI is currently 29 and I have several health problems which would would be dramatically improved by losing at least 3 stone, so I'm trying ADF rather than 5:2 in order to shift the flab more quickly.

Do I "need" to eat a "maintenance" level of calories on my non-fast days? According to the calculators given up-thread, my maintenance intake should be around 1,963 calories per day, which seems high to me. After a day fasting, I feel more comfortable eating 1,200-1,500 calories the next day. I'm just concerned that this is still low enough to send my metabolism into starvation mode.

Also, should I be eating breakfast on non-fast days? I'm not a big fan of brekkers - eating too early can trigger my IBS and leave me bloated and uncomfortable for the rest of the day. Do I need to "break my fast" properly, or is it OK to just have two large-ish meals, at midday and in the evening?

Laska42 · 25/09/2012 15:12

liz you'll just have to try it and see.. I lost 2lbs in my first week and I only walk and cycle .. In the last couple of weeks i've hardly exercised at all (no excuses just haven't really bothered much!) , but yet i'm 9-10lbs down now from my start weight .... but then I did have a stone to lose ..

awaywego1 · 25/09/2012 15:22

Lurker alert waves Grin
Finally had my first fast day yesterday-after putting it off for weeks-I was dreading it but it was suprisingly ok. It was weird feeling so hungry but nothing bad happened!
I Just had tea and coffee until 3 ish when I had some pineapple then at 7 I had a spicy tomato soup with a tiny bit of rice. I had a low cal hot choc before bed.
Didn't calorie count but I would guess around 500.
Admittedly I didn't do much yesterday so it may be harder when I'm working. But I feel great today-really motivated-and focused on eating well which is very unusual. I'm planning to 'Keep an eye' on what I'm eating on non fast days but no calorie counting.
So far today I've had porridge made with mostly water, a couple of coffees, 1 choc biscuit and some homemade tomato and onion soup with a kiwi for pudding. Planning veg curry later.
Want to lose around a stone am 9.10 currently-but would be more than happy to get to 9-I'm 5.2 and this is okish for me.
It's really helpful for me to read everyone's stories and helping with the motivation so thanks! Smile
