The 5:2 Diet Thread number 18! Breaking out the summer wardrobe?

998 replies

GreenEggsAndNichts · 22/04/2013 10:51

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. (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, 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!

What a gluttonous long weekend I've had. The scales are showing it and my jeans are feeling it. I know I've stretched my stomach these last few days, so tomorrow's fast will probably be a difficult one. Equally dreading it, and looking forward to it....

swallowedAfly · 06/05/2013 22:01

elr - wine plus touchscreen = typing suddenly so much harder Smile your picnic sounded nice. did something similar this weekend.

dotty - everything crossed for you still being in the ten's tomorrow. it will be a minor miracle if i am i think Grin have had a lovely long weekend though.

it was lovely and sunny here today that'll be it till june now so i needed to let my skin out in case it never saw the sun again. it wasn't too nightmarish finding something to wear. it would have been a lot harder if i hadn't lost a stone or so and was searching my cupboards for summer things i could wear that fitted and didn't make me feel huge/overly exposed. that's worth me appreciating.

see everyone on the other side. well done to today's fasters - enjoy eating tomorrow.

dogsdays · 06/05/2013 22:16

Im with aka have spent the weekend eating ++++ today planned fast but DS & GF were off so out for lunch then coffee & cake- back to fast day tomorrow- love this WOE & this site Smile love the support & bought loads of clothes in a smaller size Grin

GoodtoBetter · 06/05/2013 22:28

Are you guys doing low carbing on your fest days or just whatever you fancy?

dogsdays · 06/05/2013 22:32

I dont have carbs stick to soup -veg & protein

peplum41 · 07/05/2013 02:15

Hi all. On night shift, so started fast at 1 am, ok so far as still digesting midnight feast. Most of you seem to have had fun today, food/drink related and otherwise. That's the best thing about this wol, the treats come by regularly.
Goodtobetter, well done on your return fast. Especially being at work. Although I do some fasts at work, I'm sat around most of the time not doing much as the people I'm looking after are asleep. Not sure how I'd manage with a real job that actually involved work!

doILooklike I've still got that f plan diet book, I think it came free with All Bran. Over the years I've bought so many diet books, low GI, You are what you eat, Atkins, Rosemary Conley, plus all the odd library book- yet none of them made much differenc

peplum41 · 07/05/2013 02:23

Oh dear pressed wrong bit of screen on phone. Anyway... 5:2 works better than the rest but you all know that.

Was feeling really fat at the weekend, convinced had piled a couple of pounds on, but measured the important bits and all reported losses. Phew. Don't know how I've got away with that. Feel as though I need to eat better on nfds, as they're starting to slide and I do want to be healthy as well as slim. Excuse long ramblings, not unleashed opinions onto threads since friday!

tiredemma · 07/05/2013 06:19

I need to fast today after the food I consumed yesterday. Mentally I must have thought it was my 'last supper'.

will let you know how it goes

Emilythornesbff · 07/05/2013 06:48

Aaaggghhh. Furious.
I started this on 9 April and was 10st 3. After about 2 weeks I was 9 st 3' then 9st 6 and this morning I am 9st 7. FFS!
On fast days I eat nothing until a bowl of watery fucking lentil soup in the evening. I NEVER drink alcohol. No sugary drinks ever. Virtually no snacking on NFDs and smaller meals than before (just seems to have happened naturally. So after singing the praises of this fuckin diet I realise it's shit and I'm going to fat forever.

Emilythornesbff · 07/05/2013 06:50

Massive handfuls of fat rou d by arse ad midriff.
And asihave 2DCs unr 3 I nev get the chance to really exercise so I'm screwed arren't I?

Emilythornesbff · 07/05/2013 06:53

AND I made a beautiful roast dinner yesterday and ate NONE of it. Just sipped by effing broth while ds and dh tucked into delicious roast chicken and roast potatoes etc.

swallowedAfly · 07/05/2013 07:04

in reality you're still half a stone down only four weeks in. i'd say that's pretty good emily. that stone in 2 weeks was freakish and had to balance itself out i'd say. now you carry on and you'll really own that 9.3 some point soon.

i've managed to stay in the tens by a whisker. fast day today and back to work which will help. will aim for 20,000 steps today.

putthehamsterbackinitscage · 07/05/2013 07:08

I lurk but haven't posted since thread 16 I think.... I am using the 5:2 forums for support as well tho....

Emilythornesbff - don't get disheartened... Have a good look at what you eat across a week and check tdee versus activity levels etc for your lowest weight....

I have found I still need to log what I eat as I have no willpower otherwise and would snack on nfds as its only berries or a small piece of chocolate or sugar free jelly ..... Etc

I have done 15 weeks now and have made some changes during that time so I eat better overall, am exercising a lot more and liquid only fasts twice a week .... That's resulting in an average loss that is still over a lb a week but my tdee is now around 1480 so to keep losing, I HAVE to exercise and burn off cals on top of fasting or I have to cut cals below BMR even on nfds....

20lbs down and 12 lbs to go.....Smile

putthehamsterbackinitscage · 07/05/2013 07:10

Oh and may be do different fast days so you can have the toast chicken Wink

catsrus · 07/05/2013 07:13

emily - um that means in 5 weeks you've lost 10lb - that's pretty good going.

Why on earth didn't you eat the roast dinner??! The whole point of this is tht you can eat normal healthy meals most of the time, you only restrict a few days a weeks and you build in the restricted days around your life. You are thinking of this like a diet - at some point your thinking will shift and you will see its a way of life where you learn to balance occasional excess with days of not eating very much.

Don't worry about exercise - I don't exercise and I still lost 32lb to get me down to a size 10-12. You can do it - but don't punish yourself. This has to be sustainable for the long term so you have to find a way to enjoy doing it. How do you feel after a 'good' fast day? Are there days when it makes more sense t fast than others?

putthehamsterbackinitscage · 07/05/2013 07:13

Roast not toast, obviously... Bloody autocorrect ....

Sad - well done on 10s.... you're proof it works too Wink

Emilythornesbff · 07/05/2013 07:16

And I'm ebf so should be burning 500cals/day just with that.
Honestly my nfd eating is great. And if I have to start counting calories all the time I might as well go to bloody weight watchers.
Serious grump at chez Thorne this morning.
Anyway. Good luck to all you post BH fasters today.

EagleRiderDirk · 07/05/2013 07:18

Fast day again today. Considered yesterday but had to batch cook for the kids so knew its be hard to fast with all that food going on. Managed to stay well under TDEE all weekend, but for the first time ever I felt really really hungry yesterday. It must have been all that food that was around tricking me.

emily - I agree with saf, give it a bit longer and you'll be really down to 9.3 - though I'd love to be your starting weight!!!! I'm on fast 6 today and haven't lost a stone yet, I also can't exercise coz of an injury so I have everything pinned on dieting alone at the moment.

Emilythornesbff · 07/05/2013 07:19

Us well done saf
The thing iscatsrus I do love it. I feel great on and after fast days and I've found I'm eating less on NFDs just by accident.
I kept yesterday as a fasting day because I wanted to stay ahead of my week IYSWIM and I ca have roast chicken today (it was a big one).
Just so disappointing to see a rise when I feel I'm being so good.
Maybe I need to go to 4:3. I hadn't done that because I didn't want to jeopardise my feeding.

Emilythornesbff · 07/05/2013 07:21

Thanks. Sorry for the tantrum. Blush

Dotty342kids · 07/05/2013 08:06

Oh well, I'm back to 11st this morning. However, after the last two days that really is no surprise and I've got two fasting days ahed of me this week (today and Thursday) so am confident that it'll be safely back in the 10s by the end of the week. There was always going to be some "bounce" but saf I'm really pleased that you've stayed in the 10s - fantastic Grin

Northstarmum · 07/05/2013 08:12

emily those pesky bounces are a pain aren't they? Really frustrating. Did you measure your waist before you started? That might give you a view on progress. And remember all the other health benefits of fasting....

I'll be trying to do that myself as its only 8 and I fancy breakfast ( probably due to carb overload yesterday) so glugging copious mugs of tea and coffee before work. Got lunch out and am going to swap pizza for salad to try and keep as low as possible. Going to be hard today. Want to lose 3lb before I go on hols in 2 weeks but since have only lost 2lb in last month that seems unlikely!

akarucker · 07/05/2013 08:18

saf I had my fingers crossed for you, and YOU DID IT! Well done!

Well, my fun weekend has resulted in a whopping and massive 5lb gain! I was only able to do 4:3 last week, and I think I can only manage 5:2 this week so, it's all quite pants really. Will I ever be able to give up ADF I wonder? There was a glimmer of hope last week, that perhaps I was gaining just a little self control on NFD, but apparently not....

Well done to everyone who has good news after a bank holiday weekend. That's a real triumph. For the rest of us...back in track!

swallowedAfly · 07/05/2013 08:25

dotty it really was by a whisker - there's probably a bar of soap between us Grin glad you're my fasting company weight twin.

thanks aka. it was bank holiday weekend and it's only just gone on so imo it will drop straight off again. don't be disheartened.

non scale victory today of putting on the lovely retro cute dress i found in a charity shop and couldn't resist and finding it fits without looking like i'm going to strain myself so i'lm wearing it.

Emilythornesbff · 07/05/2013 08:39

Ok. You are all completely fabulous.
I will measure my waist, stick to the plan, do a 4:3 this week (maybe not every week) and get out in the sunshine with babythorne (ds at CM today).
Thank you and well done to everyone who has dropped Lbs and wearing lovely frocks
