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!

Thank you jb, have just gone on the scales of terror at boots, and the good news is that my BMI has dropped to 33.9, which is still very obese but it was 36. My pre pregnancy bmi was 32 so a way to go but it feels achievable.

How's everyone else's weekend going?

NotAsTired · 31/08/2013 16:57

Congratulations MissS, JB, Somewhere and Wriggle.

Am at "in-laws" this weekend. Eating all over the place, routine and schedules completely out the window. Ah well, never mind. Smile

NotAsTired · 31/08/2013 16:58

Oh well done, Macca*. Good news.

MaccaPaccaismyNemesis · 31/08/2013 17:02

Does anyone else have to remember to eat on NFDs? Really had to force myself to eat lunch, and have probably only consumed 450cals today! Will have a glass of wine and a proper dinner tonight I promise.

MissStrawberry · 31/08/2013 17:10

I do Macca. I can easily get to late morning, early afternoon without eating and nor do I want too so it isn't that I am depriving myself.

JB30 · 31/08/2013 17:29

The only thing I can't forget us food! I could do with a dose of the forgetfulness.
I am really struggling on nfds with eating breakfast, I want to on 1 level but on another it just opens me up to constant hunger! Last 3 weeks, I've eaten breakfast about once a week, I don't on fd's ever so thats 2 days, but on 3 of my nfds I don't either. I seem to be on 16:8 constantly, not sure if its good or bad? My calorie deficit over last 2 weeks is 6000 over the 2, although not sure with mfp if its counting my exercise too?
Anyone else like this?

SomewhereBeyondTheSea · 31/08/2013 19:00

Yeah I've found it's a lot easier to just skip breakfast as a matter of course. I don't miss it (not hungry in mornings) and it gives me more leeway with the rest of my day. I remember I used to do this at school as a teenager and into my 20s, the point I started eating breakfast is also when I started putting on weight. Go figure Wink

(I know it doesn't work for everyone btw - some people really need to eat brekkie and that's fine too. The thing I like about this WOE is that you can adapt it to fit round what suits yourself).

SomewhereBeyondTheSea · 31/08/2013 19:16

Oh also I've been meaning to say for a while, I find that when I really want a snack (yes I KNOW ...), home-popped popcorn with just a bit of salt on it is absolutely the most calorie-efficient way of getting that snacking hit. I recommend it ... Smile

eatriskier · 31/08/2013 20:14

Well done on all the SVs and NSVs today.

I've decided to hit the world of fitbit. Very interesting so far. Seems to think I've overeaten today, but then it thinks I just existed without doing anything until about 4pm Wink. I feel all modern.

BsshBossh · 31/08/2013 20:15

Macca no I don't have a problem with forgetting to eat; I'm a foodie who loves thinking about what to eat at my next meal. But my appetite has diminished as the stones have dropped so I am just eating far smaller portions. But I generally always remember to eat :)

HellesBellesThinksSometimes · 31/08/2013 20:35

Another horrendously splurgy day thanks to the worst pms and period pains I've had in 20 years. Is this how the menopause starts with the same hormonal suffering as it all started?

MissStrawberry · 31/08/2013 21:03

Today I have had a stuff my face evening. I don't feel guilty and I don't hate myself Shock. That's a first.

MissStrawberry · 31/08/2013 21:04

I don't know Helles but my TOTM is much worse than it used to be and I am wondering if it is my age Hmm.

HellesBellesThinksSometimes · 31/08/2013 21:52

I'm 35 MissS

MissStrawberry · 31/08/2013 22:00

Much younger than me then.

mummyof2girlsx · 31/08/2013 22:16

don't post here very often but I have been following this WOL since October, so coming up to 1 year! Lost about 21 lbs in total. I am just wondering if anyone else has the odd binge day/night? I am having a hungry day and can't seem to stop eating!

Talkinpeace · 31/08/2013 22:19

Mummyof2
21lbs is excellent
yup. the odd "stuff it, cheese beckons" day is perfectly normal.

mummyof2girlsx · 31/08/2013 22:29

TIP thank you that makes me better! I have had cider and chocolate and crisps Blush was very yummy though Grin. Doesn't happen too often so will not beat myself up too much.
One more question, can anyone recommend a good yoga DVD? I am a gym bunny and do lots of aerobic/interval training but would like to try something different :-)

postmanpatscat · 31/08/2013 22:47

Well done wriggle and mummyof2

eatriskier I lurve my Fitbit :)

SchrodingersFanny · 31/08/2013 22:50

I'm thinking of starting this. I've got the book, read some and looked at website. I'm 2 stone overweight since having dd a year ago. I'm doing slimming world, which has worked in past, but it doesn't seem to be happening this time, losing 1lb a week average, and it seems so limiting and difficult to fit with our lives.

Also I hate buying all the "low fat" stuff like Muller lights, I'm not convinced its that good for me, and would rather eat normal food. If that makes any sense.

I'm a bit scared of the fast days, but I suppose I don't know until I try!

mummyof2girlsx · 31/08/2013 22:59

SchrodingersFanny go for it! I tried so many 'diets' without much success. I heard about 5:2 in october and I haven't looked back since. I rarely post here but I often read the threads and the support is fantastic. First fast day is hard but I promise it gets easier!

Talkinpeace · 31/08/2013 23:00

Mummyof2
Yoga is much much better in a class with a teacher a so much is about posture and alignment that is really hard to work out as you cannot see your back ....

Schrodinger
You are so right that "low fat" is generally over processed junk and best avoided
Fasting is a lot easier than you might think .... skim through the tips and hints thread as several of us have posted timescales / weekly plans / ideas to help people take that first step into the unknown

mummyof2girlsx · 31/08/2013 23:26

Will look into classes at the gym. I am so used to high intensity workouts I am looking forward to something a bit different.

HellesBellesThinksSometimes · 01/09/2013 00:59

green tea
What state would I be in without my ten cups of decaf green tea every day? I am grossly overweight and have ibs!

MissStrawberry · 01/09/2013 07:32

SF definitely try it. I was worried about the fast days too but tbh it is a lot easier than you think to do it when your head is in the right place. Make sure you drink plenty, keep busy and plan your evening meal and you will be fine. I have lost 8lbs since starting it and had struggled for months to lose anything.
