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

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!

grace I also do only tea with milk only. I used to drink a lot of herbal tea but on FDs it made me feel sick so I just stopped drinking it.

I am feeling very miserable. I have weighed in this morning and my weight is increasing not decreasing. I fasted yesterday and for two days last week.

So disheartening. I have cut my booze right down on NFD's too.

Southeastdweller · 14/01/2014 16:26

I also don't bother with black tea or coffee though I've tried hard to like it. Whatever gets you through when fasting to eventually create the calorie deficit is what's important.

That reminds me I'm going to treat myself to some cream with my coffee this weekend Smile.

RavenousRunner · 14/01/2014 16:32

PoshPaula That's very hard, and very odd too. Have you possibly been eating a lot more salt/carbs than usual on your NFD? I've had some FDs where I weigh more the next day, and they've always involved soya sauce.

Southeastdweller · 14/01/2014 16:35

MorrisZapp I don't think it's a red herring at all. Me and most, maybe all of the maintainers here see this is something for life, as does Dr M and Mimi Spencer. As we all know, the word 'diet' is now synonymous with starving/bingeing/short-term fixes/yoyo-ing so we call it WOL or WOE to help us get our heads round the fact that if we want to keep the weight off we have to do some kind of IF for the rest of our lives. The psychological effect of this labelling and realising that this is actually different from diets as we knew them previously was really helpful when I was losing weight last year.

Personally I think it's unhelpful to call this a diet but each to their own.

TimeToPassGo · 14/01/2014 16:37

PoshPaula are you overeating on NFDs? I did and I found that I was just maintaining rather than losing weight. That's why I'm doing a kind of WW / 5:2 hybrid which allows me some scoffing days but is fairly low point on other days. It's working for me so far.

I misunderstood 5:2 based on the ADF diet where people really DID seem to be able to eat whatever rubbish they wanted because they were fasting every other day. It doesn't work like that with 5:2, at least not for me.

Dotty342kids · 14/01/2014 16:38

Errol! Shock
Oh, it's nearly food time! Veggie chilli (again!) for tea and then off to zumba toning so have allowed myself a Bendicks mint chocolate for when I'm back from that, and then job done.

Roll on scrambled eggs (from my chooks) on toast for breakfast tomorrow Smile

Deux · 14/01/2014 16:42

Hi, I'd love to join the thread. I'm doing my first FD today and, amazingly, so far so good.

I'm quite surprised as I normally feel really unwell, ragey and lethargic on a normal eating day if a big gap of time elapses between food. V strange.

I've been thinking about doing 5:2 for so long and just decided to start today. As a consequence I haven't been very planned with my meals.

In fact I decided to start when I was supermarket shopping. I've had the following today - one dorset cereals bar (see above), one egg and 2 tomatoes fried (no oil) sprinkled with chilli flakes. Plus 3 cups of coffee and about 2 pints water.

I've been inputting into MFP and I think I've got about 150 calories left.
Not sure what to have for dinner/tea. It's either tinned tomatoes with chilli and coriander plus some bok choi or leftover lentil dahl. I think the dahl would be more filling but I made it myself so not sure how to check calories. There's little fat in it as i made it in the slow cooker. How do I check that?

I'm hoping this will kick start healthier eating patterns and hoping to lose about 8 - 10 lbs. I'd like to do some regular exercise starting from Week 3.

Does everyone else wee a lot on FD?

ToffeeOwnsTheSausage · 14/01/2014 16:44

Gluezilla - You can do it. I had years of food issues and never in million years thought I would be able to do this WOE never mind lose weight.

ToffeeOwnsTheSausage · 14/01/2014 16:46

I'm hungry. Planning on fish and veg for tea. 2 1/4 hours until I eat it. Any suggestions? Have 888 calories left but haven't taken tea off yet.

zedzedzed · 14/01/2014 16:54

Yes southeastdweller just...yes.

Stokey · 14/01/2014 16:55

So nearly time to leave work on my first fast day and am pretty amazed how little hunger I felt.

Got quite peckish around 11 but made myself a cuppa, then had to go to the physio at lunch time so didn't have a chance to eat anything til 3. Had a mackerel salad then but am not in the least hungry. Did have a vague chocolate craving around 4 - mainly due to mackerel aftertaste I think, but staved off with more tea (just a drop of skimmed milk).

I thought I would feel much hungrier & grumpier, makes me realise how much unnecessary food I normally eat.

Thanks for all help on here!

ToffeeOwnsTheSausage · 14/01/2014 16:59

Deux - I feel that is all I do every day as I drink lots of water though think it should be more.

This is such a good way to eat. Decided on the cod, with sweet corn and left over pasta and I still have 485 calories left Shock. I will enjoy a home made mince pie after my dinner and still have 300 calories left. I feel peckish now but I will just drink the water and hold out until 7 ish.

zedzedzed · 14/01/2014 17:11

Words become intentions and intentions take root and become actions and every action has a consequence. Therefore there is power in the words we choose so we should choose them mindfully. For me this must be a WOE not a diet or I'm in deep doo-doo.

Some people who have landed here may have various and perhaps pretty dark issues surrounding food and see that this WOE marries up perfectly with already existing personality traits, mostly to do with an all or nothing personality and great struggles with feeling out of control. These traits will have led them astray when attempting 'diets' in the past and they may bear the emotional scars and physical damage from those attempts.

Some of us just refuse to live in a world without oil, butter, bread, cheese, booze and chocolate.

For some the idea that they can adopt and adapt this way of eating FOR LIFE is very freeing and a really important lifeboat and not only a way to lose love handles, although that's no less valid a reason, it 's just a different one. And let's remember that for many it's a WOL that helps them to recover from illness or guard against future diseases they may be genetically predisposed to.

So making a distinction between a diet and a woe may be paramount for some of us and just pedantic for others.

But the wonderful thing is, we're in it together.

So thanks for commenting morriszapp and southeast and everyone else. Hope you're all having a productive FD or delicious NFD.

Dotty342kids · 14/01/2014 17:20

deux I feel like I'm never out of the toilet on a fast day. Drink, wee, drink, wee, drink, wee. You get the picture Grin

ImABadGirl · 14/01/2014 17:33

on the subject of toileting, does everyone poo a lot on this woe? I don't seem to poo a lot these days Blush

Dotty342kids · 14/01/2014 17:37

Not me badgirl! If anything, a little less regularly as two days a week, there's not so much in my system I guess......... Smile

farrowandballs · 14/01/2014 17:42

Hi just checking in to share a very odd SV. I finally got round to weighing myself and turns out I'm a stone and a half lighter than I thought, - 11st 11lb rather than the 13st 6lb I'd guessed. So my TDEE is now 1400 and my BMI is 24.4. So I have a stone and a half to lose instead of the 3 I thought. Cant believe how out of touch I was with weight. Feel a bit embarrassed and dysmorphic. I suppose feels a bit more quickly achievable now. Ho hum. Feel odd.

For me it helps to think of it as a WOE rather than a diet as I intend to follow this long term as a way of maintaining once I get to my goal BMI - 21

Dotty342kids · 14/01/2014 17:48

A stone and a half??? Wow farrow that was a pretty epic bad guess Grin
Doubt very much that TDEE is only 1400 though - are you sure that was worked out correctly? When I was 11st 8lbs it was around 1800 cals...

Deux · 14/01/2014 17:59

Great, thanks. I didn't realise I could put my own recipies into MFP.

Just made the DC's tea and managed to resist.

Like the PP, I've just realised how unneccessary some of my eating is.

The biggest realisation for me today is how mindful I've been without making the conscious decision to be mindful, if that makes sense.

I think I've settled on half a tin of tomatoes and a small tin of tuna plus steamed pak choi for tea. A bit of a weird combination, granted. And maybe some pickled onions. So really 3 mini meals in one. And you know what, I'm really looking forward to it.

I know it's early days and I may crash and burn, but I think I'm having some kind of epiphany. Smile

turkeybaby · 14/01/2014 17:59

Zed - love this sentence

"Some of us just refuse to live in a world without oil, butter, bread, cheese, booze and chocolate."

Made me smile

NotAsTired · 14/01/2014 18:16

farrow I dont think your TDEE is 1400. Mine is 1485 and I am tiny (as in height). 1400 could be your BMR?
