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.

NFD = Non fast day

NSV = Non scale victory

Michael Mosley has a website to accompany his 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:

All our previous threads can be found by browsing through our very own fasting section of the site.

Another thread which breadandwine has started is a good resource for some of the tips and links 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. 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.

A HUGE THANK YOU to Greeneggsandnicht for putting together all this info and resources into one concise OP text, much appreciated by so many 5:2ers!

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

Thanks all for your feedback on exercising on fast days. I will definitely give it a go on Thursday for my next fast. Just managed a shred whilst my 15mo looked at me very quizzically Grin. And for the first time I didn't feel the need to eat straight after exercise- I just had water and I'll wait for lunch now. I was wondering if a weights workout before a fast had a similar effect too- your muscles need extra energy to recover so you'll burn more fat.

Anyway, really enjoy the format of the shred, circuits are my favourite. Will definitely try some of her other DVDs, like the look of burn fat boost metabolism and no more trouble zones once I've improved my fitness a bit- has anyone done those?

monster54 · 30/07/2013 12:40

Ohhh would be interested too wrigglebum I have just started shred and I am really njoying.

I too like the simplistic circuits routine. I know some people might find it boring but I don't want to have to keep learning new moves.

I exercised yesterday on a FD and I thought I wouldn't manage but some positive words from betsy I went hell for leather and actually killed off some appetite.

Much more achieveable than I would have ever thought since I started this WOL some 5 months ago!!

Southeastdweller · 30/07/2013 13:00

peas To not drink so much booze, you could alternate your drinks with drinks of water, which will also give you less of a hangover. Limit your carbs and have more protein...if all this seems tedious (and as it's a wedding I don't think anyone would blame you for thinking this), then just drink and eat as you please.

TMI alert!

Is everyone who bounces and struggling to lose...regular ? I've noticed that I've been losing more when I've upped my veg (including the magical sweetcorn - thanks again saf for that info) and therefore not blocked as I was when I was 'only' losing 0.5lbs or maintaining.

EagleRiderDirk · 30/07/2013 13:14

south I've started drinking 2 tbsp in water every NFD in order to counteract the blocked thing. Seems to be working fantastically!

Southeastdweller · 30/07/2013 13:25

eagle I thought of you the other day when I was in Selfridges and saw a tub of Reese's Peanut Butter...didn't succumb to buying it.

2tsp of what?

swallowedAfly · 30/07/2013 13:27

thanks betsy Smile

bshhh - next year i MUST get organised and do the same. for both our sanity's sake Wink

Southeastdweller · 30/07/2013 13:33

Sorry, I meant bounces or struggling to lose.

vieenrose · 30/07/2013 13:45

Hello everyone
I haven't had time to read up thread yet but I wanted to share my good news.
After two months of stalling, I have finally reached my goal, which was to go under 60 kg. At 59.9 kg, I'm barely there but still (that's 9 st 6)!!
Since starting this woe in Jan, I have lost 28 pounds and dropped 4 dress sizes and I can hardly believe it.
My new goal is 58 kg which is what I weighed at the beginning of my pregnancy with DS1 10 years ago.
I am so chuffed! Every other diet I tried to get rid of my not inconsiderable baby weight failed miserably.

EagleRiderDirk · 30/07/2013 13:48

south of lemon juice! apparently its doing nothing to help me sleep or concentrate though Wink The Reese's peanut butter is lovely. But very very calorie laden so it treat only here.

Well done vie

wrigglebum · 30/07/2013 14:01

Vie, that's amazing, well done!

I've got really into peanut butter. Instead of two bits of toast with butter and honey for breakfast, I'm having one bit of toast with peanut butter. Keeps me going a lot better. Just made my own peanut butter in the food processor, it's yummy. The shop I went to yesterday only had peanut butter with sugar in (which I don't like), so I just bought roasted and salted peanuts and blitzed them. It's delicious, but next time I'll try and get peanuts with the skin on for the fibre (like the Whole Earth peanut butter I love).

Talkinpeace · 30/07/2013 14:05

vieenrose
WELL DONE
and great that you came back to tell us - because your success proves to those who are currently stuck that there is light at the end of the tunnel

crazy8 · 30/07/2013 14:14

Hi. I need help. I started this diet 3 weeks ago and although I lost a couple of pounds in the first week, since then I haven't lost any. I feel bloated.
I fast on a Monday and Wednesday. I realise I need to be reasonably good on the non fast day. I'm 5'3" and weigh 9st 11lb. I would love to go down to 9st. What am I doing wrong? Ps I went for my first jog in a month today as I realise I haven't been exercising enough. It's tough when the DC are at home. Am 44.

MelanieCheeks · 30/07/2013 14:30

vie excellent, well done!
crazy8 it can take some time for your body to get the message - I'd say at least a month. You don't have much to lose, so it'll be slow. And you've recognised the need to exercise!

BetsyBell · 30/07/2013 14:36

crazy8 Have you checked out your tdee to ensure you're not over-eating on non fast days? Are you ensuring that there are reasonable gaps between eating meals (ie not snacking)?

I know in theory this WOE is not about calorie counting but we have to start with logging calories just to make sure we're not over-eating by accident (most of us were, hence being here).

As Melanie says, you haven't got much to lose so it might be slow.

I'm bothered about you feeling bloated though - what's making you bloated do you think?

OP posts:
crazy8 · 30/07/2013 14:52

Thanks Melanie and Betsy. I figured out my TDEE yesterday. So am trying to keep to that today. I think the bloated feeling may be to do with me being due to start my period. Will keep gaps between eating. Do you keep gaps on non fast days as well as fast days? I am a grazer.

BetsyBell · 30/07/2013 15:05

Crazy8 Grazing's not good I'm afraid, you need to let your body have a break from constantly digesting - even on NFDs - so attempt to aim to limit it if you can (I'm still working on it Grin). Also it's really easy to eat more than you meant to if you're nibbling away. It's hard if you're due on though.

As you've found out, this isn't a miracle weight loss diet, but it will help you learn good habits and eventually your eating habits will change and the weight will come off - and stay off.

OP posts:
crazy8 · 30/07/2013 15:06

Duh!! Have just re-read the title. I will endeavour to skip all snacks. Blush

Talkinpeace · 30/07/2013 15:10

:-) The title of this particular thread was mine .... as my motto is
NO SNACKING
do your utter and utmost best to only eat at meal times - even on NFDs
and try to have gaps between drinks - a big drink once an hour is much better for you than constant sipping

your digestive tract needs time to hoover into the corners before the next load of food is trampled in ....

vieenrose · 30/07/2013 15:11

Thank you all for your kind comments

Now I'm wondering how I can avoid putting it all back on during my 4 weeks holidays, which will involve a lot of eating and drinking and are coming up at the weekend.

crazy8: grazing is definitely a no no but you'll see, you'll get the hang of not snacking in no time

BetsyBell · 30/07/2013 15:17

vieenrose I'm planning to attempt mostly 16:8 days on my holidays, I'm not 5:2ing while away. I am realistically expecting to fail to stick to the 16:8 thing too but skipping breakfast should be relatively manageable... BUT, I'll more than likely put on a few pounds but I know they'll be easy enough to shake off again :)

OP posts:
EagleRiderDirk · 30/07/2013 15:18

crazy Are you grazing on FDs? If so then theyre the best days to stop grazing on, and give yourself your calories for 1 or 2 big rewarding meals. If not then everytime you feel like grazing just remind yourself you cope perfectly fine on a fast day, grab a large glass of water and tell your stomach to sod off!

Despite the almost constant rain here, my thermostat says its 24 degrees. My kids are in shorts and t shirts and are happily warm. I, on the other hand, am sitting here shivering like crazy despite being dressed in jeans, a top, winter socks and a dressing gown and nursing a large cup of coffee. Its not even an FD today!

crazy8 · 30/07/2013 15:29

Thank you Talkinpeace and Eagleriderdirk. I realise after reading more of this thread that grazing is my biggest problem. My first two weeks on this diet were relatively easy however I really struggled yesterday. My 3 DC are at home so am constantly feeding someone. Although I split my meals into a lunch and dinner I was tempted to divert some of the calories into snacks during the day.
I have learnt my lesson!

bibbetybobbityboo · 30/07/2013 15:52

Can I just check if I'm understanding this properly, I've read through a few threads and am thinking ill give it a whirl as it kind of fits with my natural pattern anyway in that some days I just don't fancy eating much and other days I eat loads. Can I say eat an evening meal with the family about 6 pm ish then eat a small sub 500 cal lunch the next day and then eat my evening meal that evening at about the same time, then the next day eat normally. Am I still going to be getting some health and weight loss benefits from this?

Dotty342kids · 30/07/2013 15:57

vieenrose that's spectacular, well done! Before and after photos most definitely needed I reckon!

bibbetybobbityboo · 30/07/2013 15:59

I mean a normal evening meal btw, the same as the rest of the family.
