The continuing thread for those of us following the 5:2 fast or other forms of fasting such as 4:3, ADF, or daily 16:8.

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 normally - or approximately your Total Daily Energy Expenditure (TDEE - see explanation below). 4:3 is the same except you fast on 3 days in the week. Alternate-day fasting (ADF) is just how it sounds; you fast every other day. 16:8 is another form where you stick to only eating in an 8 hour window each day, therefore fasting for 16 hours each 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 or app 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 TDEE calculator to help you figure out how many calories you should be eating in a day.

NFD = Non fast day

NSV/LSV = Non scale victory/Lifestyle (change) victory

Michael Mosley has a website to accompany his book on the subject. Please go check it out, as he's the whole reason most of us are here!

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

Tips and Links : 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!

Inspirational: eatriskier’s thread has some lovely inspiring stories which are worth checking out if you want some motivation to get started or keep going through a plateau. Please add your own too.

Recipes: frenchfancy has a recipe thread over here, please post any low-calorie recipes there so they don't get lost in these bigger threads!

Exercise: bigchocfrenzy has an incredibly informative and helpful exercise and fitness thread for discussion and advice on combining 5:2 with an exercise regime.

Maintaining: 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.

Other links
This is a BBC article regarding Michael Mosley's findings, which was featured on Horizon - link to that programme here.

This Telegraph article comments on the diet and gives a brief overview by Dr Mosley himself, very informative if you're just starting.

This blog post 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.

This link nicely demonstrates that there are many body ‘right’ body shapes and types, because what we are actually aiming for is low body fat for fitness and health.

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 article 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. (Though anecdotal evidence from these long-running threads may suggest otherwise…)

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 way of life!

Dotty not homemade, just a New Covent Garden carton (butternut squash and sweet potato). Homemade soups are my next cooking thing to tackle.

I always do fasted training (especially for cardio). Apparently the best time to do fasted exercise is after a good long period of fasting eg 16 hours or longer and ideally soon before you break your fast (so you can re-fuel).

nouvellevag what type of fasting did you do when younger and why? .

nouvellevag · 13/01/2014 13:38

Thanks zed!

This is why I'm hopeful about 5:2 - I enjoy food and cooking way too much to ever give up all the things I love! I really think I'll find it easier to get in the calorie deficit this way than by changing everything I normally cook. DH is not fat but is keen on the health benefits so is thinking of doing it with me, hurrah.

Your tomorrow's dinner sounds lush. :)

ErrolTheDragon · 13/01/2014 13:41

I've always much preferred exercising before breakfast anyway.

FD here; its DH's third - he woke up and announced with surprise that he wasn't really hungry! So we went for a walk - absolutely unheard of for him to do this on an empty stomach. He's scrambled himself a couple of eggs for lunch, I had a sachet of miso.

I really need to get down and do some work now.

nouvellevag · 13/01/2014 13:45

Bssh, bordering on eating disordered, really - I won't go into great detail in case anyone doesn't want to see that sort of thing without warning, but I would fast for days and rarely ate more than one meal in a day. Lost lots of weight, and eventually started getting vitamin deficiencies, losing hair and stuff. Not healthy. Then I ballooned back up anyway when I started eating proper meals, so that was a waste of time.

I am in a much better place now so hoping I can tackle this healthily.

BigChocFrenzy · 13/01/2014 13:46

Today I noticed my changed (by 5:2) habits in the canteen:
Shock

  • I wasn't ravenous, even though I had only a 250 cal healthy breakfast, instead of the 1200 cal fry-up / pastry orgy I used to have
  • I left some of my chips - they became only an occasional treat, but I no longer like them
  • so I added a mixed salad instead
  • I only had 1 rice pud glass instead of 3 or 4, and no choc cookies or muffin for later
  • so I took a kiwi fruit instead
  • to eat after my 10min lunchtime walk, which is also a 5:2 habit.
  • I won't want anything more until after this evening's spin.
  • I feel full of energy, physical and mental, even though it's Monday.

Maybe all these changes are why this morning:

Grin Grin Grin SV: under 9 stone !!!

56.8 kg, 8 st 11.2, BMI 22.2

OK it was after Sunday FD, with its usual 2-3 hrs fasted training, but still, I weigh daily and it's the 1st time. I know I shall reach this SV after NFDs too, with a little patience.

ImABadGirl · 13/01/2014 14:04

Need help today ladies, already had 411 calories and am feeling it today, note to self don't eat bread on a fast day....only had 3 slices of dry toast and when I looked at the cal content it was 411 Shock

Eatriskier · 13/01/2014 14:10

411 calories on 3 slices of bread? How thick were the slices? Shock

curveballs · 13/01/2014 14:13

Wow, well done bigchoc, that is amazing Smile

curveballs · 13/01/2014 14:14

Wow, well done bigchoc, that is amazing Smile

ErrolTheDragon · 13/01/2014 14:16

The medium sliced wholemeal we've got at the moment is 96 cals per slice so thick sliced could easily be that 137!

RavenousRunner · 13/01/2014 14:19

ImaBadGirl - I'm with you, was feeling fine and then had soup and a roll (soup was 225, not sure about the roll as there was no nutritional info) and now I feel AWFUL. Headache, general misery, dreamy thoughts of Club bars I know are in fridge...

Someone smack me!

ToffeeOwnsTheSausage · 13/01/2014 14:20

mscnile - I would cry if it was a bird. I love birds!

BigChocFrenzy - well done you!!!

Does anyone else feel weak and a bit out of it on FD? And what do I need to do about it?

Off to get more water now.

ImABadGirl · 13/01/2014 14:29

It's Warburtons 5 seeded thick sliced loaf, bloody bread, need to keep myself busy today!

LilyJoAndMe · 13/01/2014 14:36

Come on girls - you can do it !

(keep drinking) Smile

Dotty342kids · 13/01/2014 14:40

My boiler has refused to produce any heat or hot water since breakfast time. This is really testing my fast day resolve Sad

MelanieCheeks · 13/01/2014 14:48

Dont eat it till you know what calories it contains!

MazzleDazzle · 13/01/2014 14:52

Afternoon!

Sending positive FD and NFD wishes to you all!

NFD here and I'm feeling great. Just finished a bowl of homemade lentil and bacon soup with crusty whole grain bread and butter. Mmmmmm!

Managed to avoid the scales again today! And I'm carrying FD habits into NFD - drinking water!, herbal teas and not taking milk in my coffee. Also doing all of my eating in two or three meals, rather than grazing.

Toffee my cat once brought in a live mouse with a broken leg and was toying with it! The poor thing was terrified. Managed to save it, but goodness knows how long it managed to survive in my garden Sad.

BsshBossh · 13/01/2014 14:54

BigChoc that's an amazing set of NSVs, topped off with a lovely SV :) Woohoo!

Chocupid · 13/01/2014 15:02

Well done Bigchoc you must feel great!

Tiredemma · 13/01/2014 15:08

1st week

3lbs off!

Grin
TheBitchesOfWeestick · 13/01/2014 15:12

Sailing through my 3rd FD here :)

Not2bObvious · 13/01/2014 15:26

Not quite sailing like Bitch (love the usernameGrin) more like lurching.
Hey, doesn't have to be pretty, just has to get done! Roll on Tuesday and eat what I want....within reason
Keep going y'all, we're doing great

MelanieCheeks · 13/01/2014 15:38

Hmmm, surviving thus far, even managed to resist my Graze box which has arrived a day early!

I'd been planning on eggs in spicy tomato-pepper sauce (Shoukshakla or something?), but husband forgot it was a FD for me, and is making some Korean barbecue rice/ beef things. I AM going running training first, even though I know that doesn't count on a FD, and I do have about 300 cals to spare for it, so I reckon it'll be a "close enough for jazz" sort of FD.

zedzedzed · 13/01/2014 15:58

Only a few more hours to go till FD grub time people.

DRINK SOMETHING

Come on, we can do it, go do something useful and fascinating until grub o'clock.

SQUATS
CLENCHES

A whole packet of Ainsley Harriet Thai cous-cous is well under our FD cals, add various veggies from the freezer and voila: an enormous portion of tasty emergency FD dinner in 3mins flat.

zedzedzed · 13/01/2014 16:03

Well done 'tiredemma 3lbs seems a great result to me.

And bitches congrats.

WELL DONE Mazzle it's so hard not to peek.

And Big Choc...too good to be true, well done you!
