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!

I have lost height too. 1/2 inch.

MazzleDazzle · 18/01/2014 10:45

Thank you Toffee! I'm on my own today (plus 2DCs of course - to be on my own own, now that would be something!) so daren't make it!

Will try it tomorrow when I know I will have other people up share it with Smile.

Haven't broken my fast yet today. Waiting until lunch time if I can. Off to DRINK some water and herbal tea!

WhenSheWasBadSheWasExhausted · 18/01/2014 10:51

mazzle well done on keeping the fast till lunch very impressed. Yesterday was a fast day for me but I had breakfast this morning was starving and poorly sick

Haven't been on the scales today but I feel thinner, I'm sure my jeans were a getting looser yesterday.

Megrim · 18/01/2014 11:03

I have spent the last 30 years thinking that I was 5'6", maybe 5'6.5" on a good day. I measured myself the other morning and I was 5'7"?

Lilliput · 18/01/2014 11:35

9 st 7 lbs after my 2 fast days this week but I know I won't be able to maintain that over the weekend.

9 st 13

Do you think excess weight makes one shorter - dragging down the skeleton?

BigChocFrenzy · 18/01/2014 12:31

I think lack of exercise after age 40 can accelerate bone loss, which could affect height more. I seem to remember bone loss is the main reason for the extreme height loss in osteoporosis.
My OP in the 5:2 ExerciseThread suggests how to help avoid osteoporosis via training.

ToffeeOwnsTheSausage · 18/01/2014 12:37

Just back from walking to the shop. Takes an hour normally. Did it in 55 minutes. NSV.

Another NSV - I looked at myself in the mirror and thought I looked really slim (I know it is all relative) so when I weighed the same as yesterday I wasn't down hearted but took heart from what I could see.

Another NSV - I used left over pastry to make a pie with left overs - chicken, ham, mushrooms, cheddar, ricotta and onion and when I sat down to eat it I thought that is really big and I am about to have just half of it.

Breadandwine · 18/01/2014 12:49

Well it's official - I've grown back that inch I lost!

Details over on the Exercise thread.

Needless to say, I am well-chuffed! Grin

curveballs · 18/01/2014 12:54

Congrats bread Smile

TimeToPassGo · 18/01/2014 13:04

hopeful do you have a recipe for your blueberry mash up? Or rough amounts? It sounds yum and good fats are a good thing in my book!

Toffee a hat trick of NSV's! :o

Fascinating about the height loss, had no idea about that at all.

Sorry to just skim and run. Yesterday was a bit too much of a feast day so skipping brekkie and lunch today. Will have a snack in a couple of hours and then dinner.

Jobyloo · 18/01/2014 13:05

hopeful hope you've had a good time at the beach #welljell!!!

waswondering yep still feel uneasy eating TDEE on NFD's so have been eating 10% below just in case of miscalculations. Am also trying not to let the numbers on the scales on NFD's dishearten me. am hoping that after the first FD next week I'll be back to this weeks weigh in and then the 2nd FD am crossing fingers that I'll be that bit lower. As for a stone at the end of April it sounds doable to me because it's only just over 1lb a week to lose. Saying that I'm no expert so would see what the experienced 5:2ers say.

Does anyone else crave carbs on NFD's??? If so have you noticed it affecting your weight? I'm not normally a carby person but after the last 2 FD's I've turned in to a carb monster so I'm making a determined effort to use TDEE on healthy food rather than tea cakes, crackers or the like.

Jobyloo · 18/01/2014 13:06

toffee nice hat trick of NSV's Smile

HellesBellesThinksSometimes · 18/01/2014 13:33

Open letter to mfp:

Dear mrp,

There are many things I appreciate about you: your barcode scanner, your easy clickiness and, of course, the fact I can say mfp easily: however, today you have me mightily confused I have input my breakfast, lunch and (planned) dinner to see if I could chance a small amount of chocolate after dinner. I found that I had over 200 calories available to use but you told me I was over on both kinds of carbohydrates, on protein and on fat. What then, mfp, am I allowed to eat to meet my calorie target? What food contains none of the major food group, contains 200 calories and tastes like a treat?

I await your reponse.

Yours Sincerely

Helles Belles

BigChocFrenzy · 18/01/2014 13:58

Toffee Great NSVs, especially that you can see for yourself how much slimmer you are - because of your determination and work.

OP posts:
BigChocFrenzy · 18/01/2014 14:10

Jobyloo, WasWondering No problem regularly eating 10% below current TDEE on NFDs if you don't feel hungry. Really important though that you feel that it is sustainable for you, so if you start to feel unhappy on that, then go to TDEE.

We advise some folk who have difficulty losing, e.g. at a plateau, to eat nearer to the TDEE of their target weight.
It is good idea then to have an occasional NFD where you eat 10% above TDEE, to avoid too large a calorie deficit on NFDs too.

Helles
make it posh chocolate and then the calories count for less ];'}

HellesBellesThinksSometimes · 18/01/2014 14:54

I was aiming for a truffle - 50 cals but contains carbohydrate (both forms), fat and protein. I was just wondering, since my nfd's are at target tdee so I need to eat the full amount to prevent deficit, what I supposed to eat in that situation.

Fropiteroles · 18/01/2014 16:31

Hi I started 5:2 last Jan under another name. Over the year I lost 1stone 7. Over a very indulgent Xmas - for example on a period of days over the festivities I went out every day to eat with people 9 days on the trot! But I said to myself, well, what to do? So I decided to just run with it. So, now am back on 5:2, and am loving already, that emptier, lighter, cleaner kind of feeling. Still got a lot to lose, but hope to be able to keep folks better posted this year as I now have an iPad rather than a Nexus. Don't get me wrong my. Nexus is ace, but for tasks such as this the iPad is better (to me......Middle-aged myopia and all that! Groan groan! :). O forgot to say I will be very happy to lose 1.5 stones per year!

mscnile · 18/01/2014 16:36

Hi guys. Trying to be a bit good despite it being dh's birthday today. Want for a run first thing but then had a full English brunch late morning, cake mid afternoon, have made curry for later - not anticipating any loss this week!

Congrats toffee on the NSVs Grin

TalkinPeace · 18/01/2014 16:36

Helles
listen to your body
you do not need to eat "up to tdee" if you are not hungry
or stress about going a tad over ...

Thanks TIP

MazzleDazzle · 18/01/2014 18:35

Broke fast at lunch time. I find it helps to keep on track. If I start eating first thing, I don't stop!

Lunch:
blueberry, cinnamon & vanilla omelette with natural yog. on the side

Dinner:
KFC 3 piece with corn on cob (no fries, a NSV)

Planning on having raw peppers with houmous later on. And maybe some toast with Nutella or peanut butter.

This will take me to 1650 cals. According to MFP I need to aim for 1780 to LOSE weight.

Mind you, I'll need all those extra cals if I'm to make Toffee's cheese and date bread tomorrow!

bluestar2 · 18/01/2014 19:13

Hello, I am new to 5:2 fasting and am looking for advice and tips as well as motivation to stick! I am 5'1" and 9 Stone 1 llb and technically in a healthy weight range ( but only just) and I want to use 5:2 to help me lose a few more pounds but more importantly to adopt a healthier lifestyle. I put on weight very easily and due to a change of job ( shifts to days) and the DC's I now wont have the time to go to the gym anywhere near as much which is what keeps weight steady for me so I am hoping this diet will do that.
I know I will find the first week or 2 exceptionally hard and will feel starved but once I get past this I think I will get used to eating smaller portion sizes overall - at least I hope I will.

Can anyone help with how is the best way to fast? Morning to morning - midday to miday ? What does everyone find the best for both weight loss and sustaining more long term?
