5:2 Diet Thread! Number 15! Our quinceañera!

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.

Michael Mosley has recently unveiled a new 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 links and tips 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.

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, btw. 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. Sorry if I haven't given credit where it's due, but it was just enough of a job getting all the links re-copied and back into one post.

Come join us, and tell us about your experiences with this diet!

saf under 10st next week? That would be good progress!!

Fast day for me, got up this morning and TMI alert - the world fell out of my bottom. Had the same issue on Sunday. Definitely no constipation here Blush

BetsyVanBell · 14/03/2013 08:23

Good scale reading this morning, slightly surpassed my previous low by a few ounces :) So aim is to not bounce up too much again.

Might as well enjoy it while I can - holiday in a couple of weeks where I"ll no doubt pack on a good 5lbs again - I guess I'm just trying to get it down to a point where at least I won't drift back into overweigh BMI again.

...Must focus on the health benefits!

...And I know I'll be able to shift it all again afterwards.

...Maybe I won't make a total pig of myself just because I usually do?

SerotoninCanEatTomorrow · 14/03/2013 08:57

Had a sneaky weigh this morning and 146.4lbs. That's 8lbs off in total and the first time I have been below 10.7 since before I got pregnant! Grin

Happy! Not an official weigh - that will be tomorrow morning, along with all my measurements Smile

monster54 · 14/03/2013 09:09

Feeling pretty disheartened. My official weigh in isn't until tomorrow but after managing my second fast yesterday I've put on a pound!!

Uuurrrggghhh!!! I'm over weight and I track my other days on MFP. What the hell is wrong with me?!? I've tried so many Ways to loose weight and after my baby it just WON'T shift!!!

Anyone any ideas? Motivation? I'm up for giving in....

Betterlatethan · 14/03/2013 09:19

[monster 54], so you've weighed yourself today AND you're 'official' weigh in isn't until tomorrow, is that right? Do you think you could be weighing yourself a bit too frequently? There are so many factors which contribute to fluctuating weightloss. I know it's hard but maybe leave the scales out of the picture for a while and concentrate on the health benefits of this WOE. Personally I have no idea what I weigh at the moment, I last weighed myself early February, but I do know that my TOM is so much better (less painful, less heavy) and for me, that's enough incentive to carry on...even though I need to lose 1.5 stone to reach the middle of my BMI.
How long have you been on the 5:2 plan? There are real plateaus on this, and they could last as long as 6 weeks to 2 months in some cases.

Don't be too hard on yourself or your body, and good luck!

catsrus · 14/03/2013 09:24

Just stick with it monster it will work - though the oddity does seem to be that some people hit long plateaus re. The weight loss. Think of the other health benefits, reduced risk of dementia, cancer and diabetes. It was that which kept me going at times - the hidden benefits.

You've only done 2 fasts FGS Smile I've been on maintenance now for a few months having lost 2 stone since August - believe me there is a real thrill in seeing yourself in size 10 skinny jeans and knowing that no matter what you eat you can always get back into them! I 'put on' 4lb last week due to heavy socialising - today, 2 fasts later, I'm 9.4 again. I'm in control - but it took me a while to really get to grips with that.

catsrus · 14/03/2013 09:26

Re the frequency of weighing - you have to find what works for you. I'm an every day weigher as it means I see the wild fluctuations and don't panic when they happen - others find it demotivating.

BetsyVanBell · 14/03/2013 09:30

When do you do your weigh in monster? According to the scales I put on half a pound just by having a cup of tea in the morning.

Focus on the health benefits for now and take a really good look at what you are eating over a week.

I don't lose weight on this unless I am mindful of my eating most days - generally I try to increase non-dairy fats (via nuts, good oils), eat loads of fruit & veg, avoid sugar & eat fewer (other) simple carbs.

A bit of cake here and there, the odd biscuit and a few cheese & crackers and the scales go up up up for me.

You have only done 2 fasts? Give it time

Your bowels can carry plenty of 'weight'.

I'm assuming your baby isn't a newborn.

monster54 · 14/03/2013 09:32

This is my 3rd week. And I've lost 1 pound so far...this 1 pound is back on as of weigh in this morning.

I can't imagine tomorrows weigh in is going to be any better as today is an eating day. I know there are platueas etc but I haven't even had a big loss?!?

Just thought this WOL wasn't meant to feel so much like a diet. Counting on fast days...counting on non fast days and I wouldn't mind if I was seeing some results!!!!

I suppose I should just stay away from the scales, but I'm terribly unhappy and I need to see some progress with this weight, ignorance will make me more anxious!

mistlethrush · 14/03/2013 09:33

Monster - I didn't actually lose weight quickly when I started this last year (actually, I'm not losing weight quickly now, just less slowly!) but the first change I noticed was getting my waist back. This year I've pushed the fasting days so that I stopped having the reasonably low but still proper soup for broth - but I have since dropped that - and this week I have happily done without the 2dsp porridge oat porridge I was having for breakfast on fast days, and managed to go all the way until the evening without anything - something I never imagined that I would find so easy when I started.

However, even doing that, my weight loss is slow. And some weeks it isn't a loss or is a slight gain - but the overall picture is downwards.

One thing I am making sure that I do is to actually eat properly on the days I'm not fasting - mainly to make sure that my body doesn't just shut off all non-essential things and simply store fat (which it is very good at) most of the time because its in 'starvation' mode. So on non-fast days I'm eating a sensible, low GI but decent amount of food - muesli for breakfast, soup for lunch and then lots of veg / protein and perhaps some carbs for supper - although I'm finding I crave carbs a lot less than I did.

I'm viewing this as a long-term lifestyle - it will take me a while to get to my goal weight, but I'm going in the right direction, and with very minor modifications I should be able to stay there reasonably easily (hopefully).

mistlethrush · 14/03/2013 09:34

When you say you're 'counting' on a non-fast day, what are you eating?

monster54 · 14/03/2013 09:34

My weigh in is Friday am's. This is my 3rd week....

monster54 · 14/03/2013 09:37

I have between 1200 - 1500 cals on non fast days.

Cereal for breakie, meal replacement for lunch and healthy dinner.

No baby is a year now and no excuse to still be this size!!

mistlethrush · 14/03/2013 09:38

'meal replacement' ?

BetsyVanBell · 14/03/2013 09:39

monster When you say I haven't even had a big loss - does that mean you have lost some or none?

Have you taken waist, hip and neck measurements yet? Or are you noticing any change to the way your clothes are fitting?

Don't get disheartened, give it time, you will have progress and most of us find our attitudes to food and hunger changes the longer we do this - it's long term, not a quick fix. The fasting gets easier and you won't have to calorie count forever, another 3 weeks from now and you might find everything feels very different.

BetsyVanBell · 14/03/2013 09:42

Monster You are likely not eating enough on feed days - a couple of days of that would be ok but you need to let go a bit at weekends (for example).

On fast days try skipping the breakfast, have a real soup for lunch and similar for dinner, perhaps a bit of fruit or carrots for a snack if you feel the need.

Look at the recipes thread for ideas, or innocent meal pots, glorious skinny soups or supermarket own brands are all good.

monster54 · 14/03/2013 09:51

Yes I skip breakfast on fast days and try to stick to at least 16 hours before breaking and have a boiled egg at lunch usually and then either soup or vegetables and a source of protein (fish, chicken) to make up my 500cals.

I lost a pound last week and that pound is back on as of this morning. I've no change in my clothes or anything....maybe just not for me :o/

BetsyVanBell · 14/03/2013 09:52

What's your TDEE? monster

onceipopicantstop · 14/03/2013 09:57

Ok I'm in need of a virtual kick up the bum!! Did my 2 fasts Mon and Weds last week, but have failed miserably to do any this week! Have started for the last 3 days and then caved by lunchtime! Very unlike me as I can be very stubborn about giving in usually. To make it worse I have been eating complete rubbish - bread, cakes, crisps...anything carb related basically! Weighed myself this morning and have put on 3lbs. So am trying to fast again today. Have a busier, more structured day today so hoping that will help. Will report back later - hopefully with good news! Wish me luck!

monster54 · 14/03/2013 09:58

1800ish....all the websites seem to differ but that's average!

BetsyVanBell · 14/03/2013 10:03

Ok, monster you are not eating enough on feed days - try eating up to your tdee on those days. Nuts are a brilliant source of compacted nutritious calories - stock up on the raw, unsalted sort. You need to eat more love!

once You can do it! Will check in on you later Wink. Get rid of the crap in the house and don't buy more.

monster54 · 14/03/2013 10:08

Urrrggghh confused I thought you had to eat 10%/15% under TDEE???

peplum41 · 14/03/2013 10:08

oh monster52 your posts made me Sad. Please give it time,and for the love of cheese have a proper lunch. "meal replacement" sounds like punishment for
the soul.

I weigh myself at least once a day, but Ive decided to record whatever the weight is on the first day of the month in my diary so I can see the figures over the following months. Im also taking measurements then too. That seems to make the quite frankly ridiculous obsession I have with Lbs less pertinent to how I feel about sticking with the wol. Infact when the battery on my scales runs out Im not getting a new one for a while(Im a bit vague on the time will leave it)

BetsyVanBell · 14/03/2013 10:09

monster Also, look at your weekly calorie allowance - ie 5 x 1800 plus 2 x 500 = 10,000 calories. If you eat less on some days you need to make up for it - I try tend to be more abstemious during the week so that I can relax and have wine and bigger meals at the weekend - and that's how this doesn't feel like a diet. What you're doing is a calorie controlled diet plus fast days, not at all what we advocate on here.

TiPs hallowed advice copied from the tips and links thread:

Think of your food on a weekly basis.
You are not 'depriving' yourself. You are saving your health and balancing.
2 days a week of fasting
2 days a week of trying to stay under your TDEE
2 days a week of trying to stay within 10% of your TDEE
1 day splurge

storminabuttercup · 14/03/2013 10:09

breadandwine you may be right, I'm still feeling a little queasy today BUT it was enough to make me think 'ok so I over ate and it made me uncomfortable' so I won't do it again in a hurry, my estimates were yesterday took me right over my tdde so trying to stick to about 1800 today (tdde is 2100) fast day tomorrow.

I'm thinking of trying a mini fast day on Monday to make up from the weekend and try and just eat tea that day. I'm at work so it's very easy to do as I work 10-5 with a lunch break at around 3 which is too late so normally wait till I get home but then eat too much.
