The 5:2 thread number 36
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!

Think I might have a accidental slip next sat/sun as its DD1's birthday and party to go to....Wink

zedzedzed · 03/02/2014 18:25

Thanks TIP

Just practising here

zedzedzed · 03/02/2014 18:27

Wow tiger well done!

bishboschone · 03/02/2014 18:40

Are you all being careful on non fast days ? I think I may have got carried away with being allowed to eat what I like on non fast days.

zedzedzed · 03/02/2014 18:46

Yeah bosch I'm counting every morsel for this first month, am eating plenty of real foods though, cheese, meat, oil, cake, veg, rice, salad and tons of fish and treats like sausages and puds etc...BUT I'm counting them all and making sure I'm 7,000cals in debt under my weekly TDEE every week (2lbs theoretically)

I'm doing this to make sure I understand about portions and 'normal' eating so my NFDs aren't total binges but NORMAL...I have a wee splurge on a Saturday though.

Who else still counts on NFDs?

TalkinPeace · 03/02/2014 19:01

I do not count any more, but I certainly 'consider'
so that I mentally stay under my TDEE 4 days a week and only relax two days a week

MazzleDazzle · 03/02/2014 19:08

HandMini I'm up for no weigh February! Hmmm, now what to do with the scales...could give them to my sister, I suppose.

Haven't been on here at all. Had a weekend where I didn't count cals. Didn't go too overboard, but was eating past the point of enjoyment. FD today though! Didn't eat anything until 6pm. Not long finished one yorkshire pudding, gravy and veg. with a tiny slice of chicken breast. That will be it for today, other than water, herbal tea and black coffee. Have managed to stay away from diet sodas/sugar free diluting juice, simply because I've none in the house.

DD is still ill. All manor of strange symptoms: sick (especially through the night), no appetite, rough sandpaper-like skin on backs of hand, cheeks and stomach, bright red cheeks, red spots mostly on face, but also tummy. She's got less energy than usual and a touch grumpy, but the next minute she's running about playing. Strange. It's Day 6 now and her sleep cycle is all to pot. Getting a bit tired of it now tbh Sad. DH is away working for a couple of weeks, so on my own. I think she caught the tummy bug from me, but as for the rash, I've no idea. Now it feels like I'm swallowing razor blades and other DD complaining of same thing! Bloody bugs!

On a more positive note, a friend's MIL offered to watch poorly DD so I could go to gym for my fitness test to determine how much I've improved in 4 weeks. I gave it my all (despite lack of sleep) and there is a marked difference. Really pleased. Get tested again in another 4 weeks though! Will have to keep my regime up if I'm to improve again.

Hang in there fellow fasters - we're nearly there!

bishboschone · 03/02/2014 19:14

So how many cals per day do you stick to?

zedzedzed · 03/02/2014 19:20

I stick to/or under my TDEE (tool at top of original post).

Sorry Mazzle...um, that sounds suspiciously like Hand Foot and Mouth, see if there're blisters/ulcers in her mouth or get to Doc (no cure but at least you'd know(.

Poor wee lamb.
Off for dinner now, 440 cal chicken risotto...yum.

Thanks for all being around to help us get through another Monday fast. XX

ShyGirlie · 03/02/2014 19:21

Thanks all for ur FD dinner ideas! have screenshot all to save for future reference. just sticking with omelette (again) 2nite as have no motivation. am i alllowed coke zero?!

MazzleDazzle · 03/02/2014 19:27

I think I may have got carried away with being allowed to eat what I like on non fast days.

If you eat what you like on NFD, more than likely, you will not lose weight.

In order to lose 1lb a week, you need to eat 3500 cals less than your body uses! In order to find out how much cals your body needs per day, check here. It doesn't matter if some days you go over, so long as on others you're under, and the calorie deficit over the week is at least 3500 cals.

I have 2 FD, 3 days at 20% under TDEE, 2 days at full TDEE and maybe once a fortnight I don't count the cals for a day or two.

Fasting twice a week and eating what you like the rest of the time won't be enough to lose weight, especially if you're new to this WOL and are overweight.

MazzleDazzle · 03/02/2014 19:40

That's what I thought Zed, but there is no rash on her palms or feet.

BsshBossh · 03/02/2014 19:44

Your poor DD Mazzle. I'd definitely get her to the docs. My DD was ill with a bit of rash on her face last week; she was off school but we thought nothing of it as it was just a cold and fever thing. Today I took her to the docs as her skin wasn't properly clearing despite her cold getting better and was given medicine for impetigo! So glad I got her checked out!

MazzleDazzle · 03/02/2014 19:53

Phoned the docs today, but they didn't have any appointments. Will phone them first thing in the morning.

I'm praying that neither I nor other DD get it! I just don't have the time to be sick and my other DD is the worst patient ever.

MrsFlorrick · 03/02/2014 19:56

Mazzle. Slapped cheek (fifths disease). DS symptoms are identical with rash, red cheeks, high temp etc.

DD has started now and I'm in bed. In utter pain with high temp red cheeks feel sick etc.

It's the right time of year for it.

I assume I was immune. Not so. Argh. It's awful. And v painful. Only thing helps is ibuprofen.

BigChocFrenzy · 03/02/2014 20:00

RaspberryTart I do 60-90 mins fasted training without problems; most of us who have got used to fasting can train on FDs.

However, using your fat depot as fuel on 5:2 seems to work best for interval training and HIIT. Steady state cardio may increase the appetite and leave you weak - I think it is not intense enough to force fat-burning.
Have you tried sprint intervals on FDs ? I discuss these on the 52 ExerciseThread

Also, I drink a double espresso 10 mins before I start, because caffeine (for some of us) helps start the fat-burning.

I find evening training best on FDs, because then the training stops my appetite for the rest of the day.

OP posts:
zedzedzed · 03/02/2014 20:05

Yeah, slapped cheek sounds right if there's nothing on feet. Both HFM and Slapcheek are going around where we are, also Winter vomits...lovely.

You can always rock up to A&E for NHS 24 if you call first and want seen asap, the wait's not normally long, but they should at least give you a cancellation appointment at your doc's as it's for a bloody kid!

God, how horrid for you all. Hope they're all better soon.

BigChocFrenzy · 03/02/2014 20:07

Oh, poor you, MrsF. I do hope you recover soon. Kid ailments are often worse if you get them as an adult.
Flowers
btw: I had to google "slapped cheeks" as i'd never heard of it.
The NHS site says adults, especially women, who develop joint pain with it, can use NSAIDs.
It also claims that "those who have had it before are immune", but I gather you have had it ?
Hmm

bishboschone · 03/02/2014 20:12

So do I eat my bmr on non fast days or my tdee.. I'm so confused ! Shock

BsshBossh · 03/02/2014 20:14

Oh no MrsF, you too? Being ill yet having to still care for ill DC is the pits! I did it last week and though DD is still ill and off school this week, at least I'm better so can care for her better. Get well soon Thanks.

TalkinPeace · 03/02/2014 20:15

Bosch
TDEE : BMR is a memo number only ....

DorisAllTheDay · 03/02/2014 20:18

Oh, Mazzle, that sounds horrible. I do hope you and your DD start feeling better soon - and it's rubbish that you can't get a doctors appointment when you need it. And MrsF and DD as well - hope you both feel better soon.

Tigger, that's a brilliant loss. Congratulations.

I don't think I can manage no-weigh February - I'd be wondering non-stop what was happening.

Yes, Bish, I'm very careful on NFDs. I try to stay 2-300 calories below TDEE if I can - so that there's some spare capacity if I want to plan a splurge day or days for a special occasion, or if I lose control and end up eating lots of rubbish 'by mistake'. If I just ate whatever I wanted on NFDs then I'm afraid my lifelong habits would reassert themselves and I'd be gorging on buns, bagels and family-size chocolate bars. My hope and prayer is that 5:2 will reset my appetite and I'll stop wanting those things, or not be able to eat them. But until and unless that happens I have to be careful and count the cals.

BigChocFrenzy · 03/02/2014 20:23

Bish I recommend you read the OP to help, if you are confused.

However, basic rules:

  • FDs: 500 cals. Choose any 2 days, but easier if they are NOT consecutive
  • NFDs: TDEE approx.

Example for TDEE 2000, saving extra calories for the weekend:
2 x 500 FDs
3 x 1800 NFDs
2 x 2300 NFDs (weekend)

Aim is to achieve a 3000-cal deficit over the week.
