The 5:2 Thread number 22! Put down that biscuit - you can eat it tomorrow

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 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 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 Greeneggsandnichts for putting together all the 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!

SilkySocksSinkShips · 25/06/2013 20:56

Hi, this is my first post. waves

I've been umming and ahhing over doing this for a month or so now because I do get grumpy if I don't eat! But I've nearly completed my first day - yay!

A question for you expert fasters on here...

I've eaten today a handful of grapes and an apple for breakfast, a banana at lunch, another apple mid afternoon and porridge oats, no extras for dinner. Is this enough/too much or too little?

TIA :)

Talkinpeace · 25/06/2013 21:01

too little : you need some protein - some steamed fish or a bit of chicken or some pulses
personally my fallback is scrambled egg (80 calories each plus 20 for the butter) on a slice of ham (50 calories)

EagleRiderDirk · 25/06/2013 21:24

angel I'm using almond milk but only in my coffee at mo. am planning on trying a latte with it soon. in coffee its not as sweet but takes the harshness off quite well.

EagleRiderDirk · 25/06/2013 21:27

silky welcome. its best to try to get a more balanced meal in on a fast day. the key is to plan ahead. you'll be surprised what you can have for 500 calories. hope today has gone well for you

akarucker · 25/06/2013 21:31

silky often people find that eating fruit on a FD makes them hungrier, so perhaps replace the fruit with something veg based (stir fry? Salad? Soup?) to make your calories go far but keeping the hunger under control. That is, if you found yourself quite hungry. Perhaps you didn't. Sounds like you managed well on your first fast, well done.

SilkySocksSinkShips · 25/06/2013 21:43

Thank you!

Ok, more balanced - I'm on it. I plan on making Tuesdays and Fridays my fast days so will organise proper 'meal' plans for these.

Not been too bad. I've been busy today and made it harder for myself not to give in - no money = no spends on snacks! I'm hungry now but feel alright knowing I can eat in the morning.

Do/can you exercise on fast days?

BetsyBell · 25/06/2013 22:00

silkysocks Fast days are my favourite time to exercise and it's more likely to burn off fat too.

Ruby Try it out and see what works for you. I prefer having a couple of days in between because otherwise it feels like too many NFDs in a row. Monday and Thursday are my usual but they can be changed easily.

Well done to you both on doing your first fasts! It gets easier...

I tried almond milk and poured it down the sink, it was vile! I had a dairy intolerance so I'm careful and usually use rice milk on cereal but I don't drink tea or coffee.

Welcome silky and ruby!

Itsaboatjack · 25/06/2013 22:01

angel I use almond milk, only in my coffee though. I also like hazlenut and vanilla soya milk.

angelabbie · 25/06/2013 22:10

Thanks for the feedback on Almond milk, I will buy some and give it a go and if its not good it can go to the cats!!

SilkySocksSinkShips · 25/06/2013 22:25

Thank you all for the lovely welcomes :)

Good point about burning more fat. I'm aiming to lose my last stone of baby ahem, toddler weight by the end of August. This last lot seems the most stubborn to get rid of!

SauceForTheGander · 25/06/2013 22:27

Ruby I'm BF too and about to start. Though not twins!

I am thinking either doing 700 cals or 16:8 which might encourage me to get some much needed earlier nights.

I've got ten pounds to lose (ideal a stone) . Booze my downfall tonight though ...

Southeastdweller · 25/06/2013 22:39

Welcome to the fold silky and ruby Smile

silky Like Betsy I prefer to exercise on fast days.

itsaboat Thanks, I'll go into a H&B this week.

angel I just ordered some almond milk for the first time so we'll be trying it at the same time, near enough! In answer to your question earlier I've developed a knack for buying rare DVD's cheaply then selling them on Ebay for inflated prices so not especially thrilling! The real excitement of today came after work in Waitrose when I bought some salad that was reduced from £1.99 to 99p Grin

So I just did a packed lunch for tomorrow - walnut bread with pesto, salad and mackerel. This is the first time on a FD I've handled bread and I wasn't tempted to eat any of it. Quite a change for someone who used to be known for snacking on about a kilo of bread some days.

Talkinpeace · 25/06/2013 22:42

over christmas we had almond milk as that is what our hosts had : it was fine in tea and on cereal and in milkshakes

virginposter · 25/06/2013 23:35

Betsy really great post from you (page 7) re attitude to this woe Smile

I used to make my own almond milk and soon got used to it. I used it in my porridge but as I no longer eat breakfast, I have no need to make it now.

virginposter · 25/06/2013 23:43

Angel I too am 5'5" and started this woe at 12st 2lbs. Never in my wildest dreams did I imagine that less than a year later I would be 10st and a size 10 and happily maintaining easily.
Just keep going, doing what you know works for you and one day you too will be amazed when you reach your goal.

Tortoiseonthehalfshell · 26/06/2013 00:43

Ruby, the original 500 cals was worked out on the basis that it's roughly 1/4 of a woman's TDEE - so your 700 would work perfectly if your TDEE is 2800, which it might be if you're still breastfeeding the twins regularly. I know you said upthread that you were told to add 1000 to your TDEE when you were exclusively bf, and 1800 is quite a common TDEE (that's mine; I'm 5'4", 61kg and lightly active).

Second fast day of the week here today. Am in office after sub-zero morning, with the heater on and a cup of tea, and feeling motivated. I even had black coffee this morning; I've never been able to tolerate it before, and I'm teaching myself.

Does anyone else find that they get nauseated on fast days? I have always responded to hunger with nausea feelings, and I really notice it still, even after two months of this, at least once or twice a day. Once it was bad enough that I actually went to the bathroom to puke, and then had a restorative biscuit, but usually it's mild.

swallowedAfly · 26/06/2013 06:53

10.2 today bizarrely Confused

haven't been doing true fasts but have been doing the eat in a small window business.

Tortoiseonthehalfshell · 26/06/2013 06:57

How are you feeling generally, SAF? You took the week off work, right?

3.30pm here and I've been so glued to the Texas filibuster that I totally didn't think about food all day.

swallowedAfly · 26/06/2013 07:06

all a bit complicated by going for breast check up and finding out labs had found signs of dcis in my removed tissue tortoise. had thought i was on the mend and coming out other side but now seems there's a whole new shelf of shite ahead. waiting on getting a call to be given an appointment for a specialist. trying not to panic but all sounds like breast cancer. bit calmer today than yesterday when i found out.

am back at work but not much good to them with my head screwing. have a meeting with my boss this morning and will fill him in on what's going on so they know. meant to be off on holiday next thursday.

Tortoiseonthehalfshell · 26/06/2013 07:30

Oh no! SAF, I'm so sorry to hear it.

BsshBossh · 26/06/2013 07:34

Oh saf so sorry, really thinking of you, we're all behind you.
