The 5:2 thread number 27 - Season of fasts and mellow rumblingness (with apologies to Keats)

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!

Talking of eating mindfully, I've been using the Headspace meditation app recently and have just paid for an annual subscription and bought the Headspace Diet book. I'm thinking it will help me with NFDs to the point when I won't need to use MFP to control myself.

Emmabryant123 · 28/09/2013 19:15

Well I've eaten today

12pm: cheerioes with semi skimmed milk and a banana (medium size bowl)
5:30pm: rogan josh chicken curry with a jacket pot, small naan, two poppadoms
7:00pm: craving an ice cream but had half a banana, a satsuma, some red and green grapes in a bowl.
Find it hard to calculate calories for the curry but I estimate on mfp between 1750-2000 eaten today which is not to bad I suppose.
I over estimated most things as I didn't weigh the chicken or the jar sauce .
Also forgot to add the small amount of butter on my jack pot.
Not to bad though.

Fasting until tomorrow's late lunch/early dinner at about 3:00-3:30pm at my mums. Spag Bol n garlic bread. Going to try and resist the garlic bread.

Then back to 500 cal fast on Tuesday.

Emmabryant123 · 28/09/2013 19:15

Forgot to mention drinks have been:
Sugar free squash, water and two cups tea with semi skimmed milk.

zombiesheep · 28/09/2013 19:28

Hi everyone! I'd really like to start this 5:2 diet, I'm thinking of starting tomorrow but I'm scared of being hungry... :o
Do I need to prepare or anything (eat less/more today?)

Also on NFD, do people tend to avoid carbs? I don't really want to do a low carb diet but I know cutting most of them out would be better for me.

Thanks!

Talkinpeace · 28/09/2013 19:40

Hi zombiesheep , welcome
Do not be scared of feeling hungry. Its the feeling of fat burning.
Drink plenty, stay busy and eat LOADS of vegetables for your 500 calories and you'll be fine.
WE mostly avoid carbs on fast days as its easier
but by golly we don't on other days (pizza last night and naan bread and curry tonight ...)

wrigglebum · 28/09/2013 19:59

No carb avoidance here on NFDs either, but I have cut back a lot- lots of carb makes me bloated now so I have a smaller portion. Plus I try to have a low carb breakfast on NFDs now so it doesn't set off the hunger monster.

zombiesheep · 28/09/2013 20:01

Thanks for the help!

Bit worried about the side effects of not eating, too... Does it affect concentration etc for example, when I am sat in lectures?

Alibabaandthe40nappies · 28/09/2013 20:14

zombie welcome :) I actually find that during the day my concentration is better, especially in the early afternoon. By 5pm my brain definitely isn't working at top notch.
I also don't avoid carbs on NFDs. This evening I've had a lovely pile of mash with my chicken casserole, last night was chips with steak.

I didn't eat any breakfast today, just wasn't hungry for it. Had lunch as normal and then no snacking until dinner.

Hope everyone is having a good weekend! :)

zombiesheep · 28/09/2013 20:18

Okay I'm gonna do it tomorrow! I'm excited but nervous! :o I don't really have much weight to lose, few lbs would be great but I just want to feel better/less sluggish!

Thanks for the advice, I'm sure I'll be back!

Salbertina · 28/09/2013 20:21

Zombie- i find i notice my hunger, if that makes sense, but don't always take it seriously! Generally passes if you distract yourself/have a drink.

southeastdweller · 28/09/2013 21:28

Welcome zombie. Don't bother with high carb foods when you're fasting. To give you an example, two pieces of toast with butter is more than 300 cals and you'd be hungry soon after eating it. Really not worth it. Remember that you can have it tomorrow.

MissStrawberry · 28/09/2013 21:32

zombie - I was scared too but let me tell you these fabulous posters have got me through and I have lost about 10lbs along the way Grin.

MelanieCheeks · 28/09/2013 21:51

Zombie, you'll never know unless you try.

Hunger is copable with - serioulsy, your body can cope without food (or water) better than it does without sleep.

Carb-avoidance - before I discovered 5:2, I realised that my body had difficlties in coping with lots of carbs. If I had toast for breakfast, a scone mid morning, and a sandwich fro lunch, my stomach would be in agony by mid-afternoon. So I've learned that I do best on 100-150 g carbs per day. BUT everyone is different, and you should experoment to see what carbs on NFDs work best for YOU. On a fast day, carbs will really use up your calorie allowance and are best restricted for that reason.

Dotty342kids · 28/09/2013 21:52

zombie, welcome to the thread! Loads of helpful advice and info here. I avoid carbs mostly on fast days as they are lots of cals and they don't fill you for long. On non fast days I find I eat less carbs than I used to as I've realised how much they bloat me up but when I want them, I eat them Smile

BiscuitsAreMyDownfall · 28/09/2013 23:05

zombie I started last week and had a FD Monday and watched my calories for the rest of the week. Did plan to have a FD Friday, but due to certain circumstances I ended up sticking to my TDEE instead. Everyday knowing my evening meal was a certain amount of calories so I adjusted my daily allowance at work to fit in with my allowed TDEE for the day. By Friday I just wasn't hungry so I'm thinking that it just takes a bit of time for your body to get used to not consuming certain calories at certain times.

The one thing that got me through my first fast day last Monday was knowing that hunger comes in waves and that I just need to wait for it to pass. I just thought to myself to ride the wave and it really worked. All week I planned what I was going to eat and stuck to it and by Friday I just wasn't hungry. I really didn't think I could do it, but I can.

I was planning to do this WOE for a while, but thought my hunger was stopping me, now I honestly have the impression that the more you eat, the hungrier you are. Basically if you eat lots then your body gets used to needing more food, but you can train your body into thinking it doesn't need as much and you're not as hungry. Hope that makes sense.

Anyway sorry for waffling there good luck tomorrow zombie, let us know how you get on.

BiscuitsAreMyDownfall · 28/09/2013 23:06

BTW I've lost 2lbs in my first week zombie

HellesBellesThinksSometimes · 28/09/2013 23:18

Oh my word Emma I would not cope at all with that menu. I really struggle to have more than one portiin of fruit without getting sugar peaks so I have lots of veg for my other 5-a-days. Ditto with carbs like bread, rice, potatoes. I normally have one slice of wholemeal breadand one other portion of carbs - usually cous-cous or quinoa. Itherwise I end up with energy dips and snacking! It just shows how different everyone is.

Great summary Buscuits sobmuch of what you said there made sense to me but I hadn't thought about it.

Blowout today - my second of the week. The problem - I was too scared not to drink alcohol knowing that my friends would be all Shock - not that I wasn't drinking but that anyone wouldn't be drinking on a girl's night in. Willpower=0. Calories=2400 (restimate as I didn't keep track but picked)

whimsicalname · 29/09/2013 00:22

The shame: my 7 year old just did the 3rd work out from Ripped in 30 (like the shred) without breaking sweat. I, however, hobbled up the stairs after, still regretting eating my own and then finishing boys' frozen yoghurts. Repeat after me 'i am not a bin. I am not a bin'.

Hasywell · 29/09/2013 08:10

Morning all, haven't posted much or often but just wanted to quickly share progress to date and a NSV! Since January have lost 35lbs so far. There have been plateaus but what I have noticed is my body shape changes during those times and I seem to lose inches rather than pounds! Have between 8 - 14lbs to go! I am 5.7 and 8lbs would take me to 10 stone exactly. My NSV is that for the first time in years I have bought size 10 trousers and skirts! This is a good example of what I mean re losing inches rather than pounds - I have been 10.8 all month but clothes do feel looser and I am now venturing into a new size for my bottom half!

Also was given new motivation this week as have been lucky enough to secure a place in the London Marathon 2014 through the ballot - now it is the the time to tone up and get fitter.

More importantly for me, as a head of two primary schools which can be pretty stressful at times, I haven't been ill since following the 5:2 WOL and have so much more energy and emotional resistance! This will also be because what I do eat is so much healthier too and my body seems to want so much more fish, veg and fruit!

Sorry for long post but just wanted to share successes - this is definitely a sustainable WOL for me!

lucyintheskywithdinos · 29/09/2013 08:32

hasywell wow! I'm really impressed with your NSVs. I find the losing inches during plateaus thing really heartening.

biscuits it makes sense to me. I feel the same, really surprised by how hungry I am not during fast days!

NFD here again. Off to Manchester to protest at the Tory party conference. Might eat dinner in Manchester too.

JB30 · 29/09/2013 08:49

Wow Hazywell, 2.5 stone in about 9 months? That's brilliant. If I could go the same I'd hit my goal about February. My ultimate aim is 9st11lbs - I have dreamt of having a single number of stones for years, last time I remember being 9 stone something was 20 years ago - of course I didn't appreciate or enjoy it - classic case of youth wasted on the young. You must be over the moon as a size 10, I'd be wearing my clothes inside out to show the labelGrin
I've just about recovered from my hangover from Friday. My exercise plans for yesterday changed slightly. While I didn't manage a jog, I did manage some Davina, I actually felt great for a while after - but the dreaded headache and munchies returned with a vengeance. FD tomorrow and I'm determined to stick to 500 as my last few fasts have been a bit lacklustre. Have a lovely Sunday y'all

HellesBellesThinksSometimes · 29/09/2013 09:33

Brilliant post Hasywell inspirational.

eatriskier · 29/09/2013 09:36

whim oh dear... Grin

hasy very inspirational post. good luck with all the marathon training.

KinkyDorito · 29/09/2013 10:21

Hi all. I started low carb 5 weeks ago and have found it is really suiting me in terms of the health benefits that I've had. But, DPs came over yesterday and they are both doing the fast diet. They have never dieted in their lives, so it's quite odd, but I think they are drawn to the longevity claims of following IF as well as losing excess weight. They were very convincing, so I've ordered the book and intend to combine the two approaches. Since going low carb, my hunger has been much easier to control so I'm hoping it won't be too tough... we shall see!

wrigglebum · 29/09/2013 11:25

I agree with hasywell about the plateaus being when your body shape seems to change. I really found that when I had a plateau.

Really crap sleep last night due to teething toddler and I feel awful so today will be a sugary carb fest I think. Off to circus later too and we promised DS some candy floss and I don't want to miss out on it too Grin plus fish and chips after.
