5:2 Diet Thread! Number 15! Our quinceañera!

GreenEggsAndNichts · 11/03/2013 15:33

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!

my bmr is 1384

my Tdee is 1903 but wonder if i need to adjust to allow for my wheelchair ( when out im in a powerchair so not using anything much indoor si use a manual chair

BetsyVanBell · 17/03/2013 10:40

THC you can work out your TDEE here which lets you put in your activity levels.

To fast you just need to keep under 500 calories over a day. A bigger gap as possible between your last meal and eating those calories is recommended in lots of reseach for all the health benefits but you can work up to that. A 16 hour gap is easy as it's really just skipping breakfast. However, Michael Mosley opts for a different eating schedule that doesn't have that long a gap and he still achieved all the amazing health benefits so who's to say who's right?!

Hope that helps.

swallowedAfly · 17/03/2013 10:45

bvb where in your cycle are you? it may be that stalling you.

BetsyVanBell · 17/03/2013 10:57

THC Cross post! Why don't you use My Fitness Pal or similar to record your normal, current daily eating for a few days and see if that correlates with that calculation. Am I reading correctly that you are already at maintaining weight? If so then use your current eating level as a guide and make adjustments if you need to after starting fasting depending if your weight moves up or down too much.

BetsyVanBell · 17/03/2013 11:01

saf No idea, haven't had periods for years thanks to mirena iud! However, boobs have been unusually tender so I could be pseudo pre-menstrual I suppose. Maybe I'll suddenly shift down again next week. I'm in no rush - I just bought (and am wearing) a size 8 top so a NSV and a half!!

BsshBossh · 17/03/2013 11:19

bvb my shorter eating windows (8 hours or less on non-fast days) always makes me feel stuffed but when I review what I've eaten it's generally always under or at my TDEE. But then my stomach capacity has shrunk too so that plays a big part.

I no longer feel guilty about "overeating" on the weekends. This is a huge achievement for me as a) I don't want to feel guilty about food and b) I now have strategies in place to redress the balance over the course of the week.

I am totally in control again :)

jenniejenjen · 17/03/2013 11:53

Hello! Grin

I've spent hours trawling through all the threads...great to have so much advice and support.

I have just finished my 4th week on 5:2; and, d'oh! I didn't take measurements to begin with (who wants to when they're unhappy with their weight...even if it's for the sake of the bigger picture...takes a lot of balls) so I have no specific stats...but I do know the muffin top is a lot less, and my tights fit without digging into me.

That's actually what got me started on this in the first place - I could see I was starting to pile weight on, but ignored it, or put it down to a "bad day". I then started to notice my tights didn't fit...over the space of a week or two I was chucking pair after pair back into the sock drawer in a huff ("they must have shrank in the wash!") - then realised not even the NEW ones in my size straight from the Primani packet did.

It was like through that one realisation I could suddenly see every last bit of podge, every unsightly hump and bump and decided right, I have to do something about this.

To be fair, with the amount of bad calories I stuff in my gob just for the sake of it sometimes, I'm lucky I'm not heavier than I am. I think this is because I have good weeks and bad, and sometimes skip breakfast and lunch. I'm a real late night eater...I'll have a huge dinner, some snacks, maybe more snacks, tea, cake/choc/ice cream/crisps...

And pop tarts. If there's a pop tart in the house, it doesn't last a second. I think about them longingly in the cupboard and hoover all 8 up in a day or two without even realising sometimes. So I don't buy them anymore. Devil's food @ 200 calories a piece.

This WOE appealed to me for a number of reasons:

  • I don't like breakfast, never have. It's the last thing I want when I wake up, I reach straight for the coffee and usually have a late lunch. Sometimes, it would get to 5pm before I've realised I'm hungry.

  • I'm a bit of an all-or-nothing gal, regular "diets" leave me starving, miffed and hungry after the first week and I usually break them in a spectacular family sized Galaxy filled fashion

  • I get to go out to dinner on eat days, have a slap up meal and a glass of wine or four, and not feel guilty. Wahey!

Generally I've found the fasting pretty easy, although through reading these threads I've realised I need to aim for the 16-24 hour mark without any food at all. I was doing little and often within my 500 calorie allowance, just in case I suddenly went mad for a kitkat or something - but now I've been doing it over a month it makes sense for this to be the next step. I'd been unwittingly fasting for that amount of time sometimes anyway, so why I decided to change that for the sake of the diet is beyond me!

It's always around 8pm - 12am I get really hungry on fasts and start fantising about stuff I'd never normally eat. Yesterday was a fast day and I found myself salivating over banana bread recipes, and looking up how to make the world's fluffiest pancakes.

Then I fall asleep, wake up, and lo and behold - I'm not hungry. Sometimes, I've eaten to break the fast, just coz I can.

Well, no more!

Good luck to all fasting today. Still 3 months to the summer (if we ever get one)...perfect amount of time to get into shape. Then we get to fling off our bikinis and run down the beach baywatch style.

Huzzah! Grin Wine

jenniejenjen · 17/03/2013 11:56

Er...that meant to say "fling off our towels", not our bikinis!! Blush

virginposter · 17/03/2013 12:02

On page 18 of this current thread BMJ has posted a link to Brad Pilon's Eat Stop Eat. It is 78 pages long but they are short pages and a lot of them can be skimmmed. I would like to thank BMJ for posting this (I am half-way through reading it) as even though it's stating a lot of what we already know, it is also giving a lot of information on burning fat quicker and retaining muscle whilst fasting. He sites a lot of studies and has done a lot of research so I'd urge everyone who is reading these threads to go back to that link and have a good read. Don't be put off by the size as it's easy to read and as I said before, some can be quickly skimmed Smile

HotPanda · 17/03/2013 12:50

Thanks Betsyvanbell

2063 calories is loads! So I eat that amount on all non fasting days no matter how many fasting days I do, is that right?

I've reached 16 hours, and am feeling ok. I mean, I'm hungry but don't feel like I HAVE to eat, so I am going to keep going.

NurseEzzzaChapel · 17/03/2013 13:34

Welcome jennyjenjen, your post made me laugh! I thought you were being brave about the flinging off the bikinis until I saw your second post. Grin

I have an update on my friend who has been losing about 0.2 lbs per week almost every week. Turns out up until last week's weigh in she'd lost 3 lbs in total having started on 5:2 10 or 11 weeks ago. (I thought it was 2 lbs.) She's just on the borderline between normal and overweight BMI so the slow loss isn't down to being a skinny minnie. Today is her weigh day and she discovered she'd lost another 2 lbs this week! So 5 lbs down altogether, big smiles all around. Smile

My next weigh day isn't until Tuesday so I don't know how I've done, but I feel like I've stayed about the same weight.

BetsyVanBell · 17/03/2013 13:57

Hotpanda That's right - you should aim to eat not more than 2063 calories on non-fast days. You might find some days you eat a bit more, some a bit less but if it all balances out over a week then that's brill. Once you've sussed out how much food that is you probably won't need to keep an exact record - I don't bother calorie counting at all really. Good luck and let us know how you get on :)

jenniejenjen · 17/03/2013 14:00

Haha nurseezza, I'm all for people flinging off their bikinis in the right environment...I'd never be brave enough to whip mine off on a beach though, never mind proceeding to run down the shoreline baywatch style...imagine all the wobbly bits!! Yuk.

Great that your friend has seen an increase in weight loss this week, and fair play to her for pushing on despite a pretty small loss up to that point - it seems that perseverance pays off with this WOL.

I just read Brad Pilon's ebook, really motivational stuff. A whole 24 hours without food, though?! Not even a bowl of berries and low fat yoghurt?! How do you do it, people that manage it!! I already down enough black coffee to sink a ship on fast days!

Maybe I should start with reaching 18 hours, then go from there....

BlackMaryJanes · 17/03/2013 14:16

TMI:

Ouch, so it's officially that time of the month and boy am I shitting a lot.

freerangeeggs · 17/03/2013 14:34

Hi all, I'm a lurker :) My DP and me have been following 5:2 for a few weeks now and we really like it.

I just wanted to share a recipe of mine that's only 281 cals per portion.

1/2 aubergine
2 leeks
150g fine green beans
1 small can of bamboo shoots
1 400ml can of Kingfisher light coconut milk
Simply Thai yellow curry paste (1/3 of pack)

Chop all veg up and cook for a few minutes, until leeks start to wilt. Use spray oil.
Add curry paste and cook for another few minutes.
Add coconut milk and simmer until the veg is soft.

Serve on its own or with a poppadom (only 37 cals). Makes two big portions.

I usually add some fish sauce to taste too. Sometimes vary the veg.

I'm just so surprised - I always thought easy wee curries were quite high calorie!! Not at all apparently.

BetsyVanBell · 17/03/2013 14:53

THC WOW! I take my hat off to you - very impressive! I can't imagine the motivation it takes when you have mobility issues to overcome. You look fantastic on your 'after' photo, sleek and toned. [InAwe].

Jen Loved your post - I'm not quite ready to fling off my bikini yet but hey gotta have something to aim for Wink

BetsyVanBell · 17/03/2013 14:55

Just trawled back through this thread to find the Brad Pilion book link that BMJ posted recently:

aventadores.files.wordpress.com/2013/02/brad-pilon-eat-stop-eat.pdf

Thanks BMJ :)

BetsyVanBell · 17/03/2013 14:58

Hello FRE - that looks lovely :) You could pop that on the recipe thread too so it doesn't get lost on here if you want? (Please do!) www.mumsnet.com/Talk/big_slim_whatever_weight_loss_club/1567814-5-2-Fast-day-recipe-ideas

Breadandwine · 17/03/2013 15:02

vp There are two links to Brad Pilon's Eat, Stop, Eat on the Tips and Links thread - one from SkinnyEye, first noted back in September, and one from myself in January! Smile

I agree well worth checking out!

BlackMaryJanes · 17/03/2013 15:11

To those who have read the Brad Pilon book: which are the best pages?

BetsyVanBell · 17/03/2013 15:15

B&W Oops, must have missed those Blush - mind you the the t&l thread is quite large these days... so much info to absorb! No bad thing to have such usefulness popped into the main threads at intervals either :)

BetsyVanBell · 17/03/2013 15:23

BMJ It's quick to skim through, then you can just stop at the bits that grab your attention... The stuff about the diet & nutrition industry is very enlightening (that's where I'm up to so far!).

Breadandwine · 17/03/2013 15:43

You're quite right, BVB, no harm mentioning any of these links in the main threads.

Fair point about the T&L thread - a thread specifically for links would be useful, I guess. [Hmm...]

Breadandwine · 17/03/2013 16:06

My apologies, folks! Blush

The links on the T&L thread are to Brad Pilon's blog. The link that BMJ gave is quite different - being a link to his book, Eat, Stop, Eat.

So that needs to go on the T&L thread as well.
