The 5:2 Diet Thread number 18! Breaking out the summer wardrobe?

998 replies

GreenEggsAndNichts · 22/04/2013 10:51

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. (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, 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!

barbie you can download The Fast Diet by Dr Michael Mosley if you are interested.

headintheclouds · 25/04/2013 18:08

Hi All,
barbie well done on your first day. if you do 36 hr fast on your first day you deserve a medal!
monster Ive felt bloated at TOTM.. I still weigh in as normal but disregard what the scales say ( unless they are favourable)Grin
postman I had a first post fast gain 3 weeks ago and have stayed the same since! I knew mine was due to Easter food though! Im still trying to get back down to pre Easter weight. Its a fast day for me today and my WI tomorrow..fingers crossed.
whitecat do you think the warmer weather helps. Oh for some warmer weather here in the North so that I could comment ..its blardy freezin here today. And for the first time for me Im feeling very cold on a fast day.Ive not experienced that until today..

have a good weekend all... Looking forward to tomorrow evening and a lovely glass ofWine with dinner ..love my Fridays

BsshBossh · 25/04/2013 18:14

Desperate 19 hours is terrific and you've learned a good lesson too - that, for you, it's best to save your cals up for the evening (not all fasters do or need to do this so it's personal preference).

Barbie1 · 25/04/2013 19:12

Just broke the fast 24 hours after starting. I would of carried on but dd has been ill this week and there is every chance I will be woken in the night and I really didn't want to feel so hungry that I could
Go back to sleep.

My dinner was about 470 cals, I struggled to finish it all so dh did is this normal? I still have about 50 cals to use up, does it matter If I don't consume them?

Thanks for the book recommendation, I will try to
Download onto my I phone.

So that's me done until Monday..

BsshBossh · 25/04/2013 19:40

Really well done Barbie.

I'm still trundling along on my 36 hours. Feeling absolutely fine and I think I've realised that I don't need any extra distractions, that it feels quite normal for me to be doing this.

Amazing what the body and mind gets used to.

applegate · 25/04/2013 21:06

not a good day today, fasted Monday and Wednesday but today was out for lunch and have just added up calories, 500 over tdee today. Although I had a lovely time I feel disappointed now, it feels like those calories and rich food weren't really worth what I am sure will mean a gain tomorrow :(
Oh well lesson learnt although we are away at the wknd which will be tricky eating wise... I will fast again tomorrow prior to the wknd and hope the scales are not too disappointing on Monday.

MelanieCheeks · 25/04/2013 21:41

Bar is, if you're under 500 that's fine, you don't need to hit that argent bang on.

I have a few spare so I might have a small cup of options hot choc before bed

Southeastdweller · 25/04/2013 22:03

Hi all. Just wanted to add that according to the M.M and Mimi book, grapefruits are good for fat burning, too, as well as tangerines. Half of one is only 39 calories.

BsshBossh · 25/04/2013 22:28

I'm off to bed now, hopefully to wake up tomorrow morning having eaten nothing in 36 hours!

EagleRiderDirk · 25/04/2013 22:50

Tomorrow will be my third fast day. I'm doing 5:2 and its going well so far, especially as I have a decently large amount to lose. I lost a lot years ago on the GI diet, but I'm finding this far easier. I'm combining a bit of filling knowledge from GI on non fast days, but its nice to know I can have a bag of crisp if I have calories to spare!!!!! Also, I've discovered I've not really been eating that unhealthily other than all the naughty snacks and bread overload, so that's made me feel a lot happier.

I can't believe how many of you are trying to eat nothing at all on fast days. You're all nuts and very brave. I've been more happy discovering just how much food I can shove down my throat that comes under 500 a day!

Bramblesinafield · 26/04/2013 07:18

Morning, fasters. Well, those saying it gets easier as you do it longer are spot on. I find that I can keep going until the evening now before I break my fast, one of those innocent pots is a real treat, then I have cals left over for a small handful of cereal to keep me going overnight. Another lb off this morning (after second fast of week). I know I'll bounce up, but I haven't seen these numbers on the scales in years - I now see the fascinatinon in dieting!

Bramblesinafield · 26/04/2013 07:21

Also, I'm now going 'omg!' In awe at the scales rather than in horror. I've never managed to change wol for healthy weight loss that has worked so well before, and I don't feel as if I'm denying myself as the days off I can eat sensibly but eat everything I enjoy.

Inlovewithchocolate · 26/04/2013 07:22

Morning everyone.. I haven't posted much recently.. For the past MONTH I hit a plateau but this morning I have reached an all time low of 9.10.5. This is amazing.. So my message is please do not get disheartened and give up. I nearly did as was getting frustrated. Am so proud of myself.. I mixed my calories around a bit my doing mini fasts too and I think my body just didn't know what to expect.... My goal is 9.5.. Woohoo summer here I come.

Southeastdweller · 26/04/2013 07:24

Morning all.

Three pounds off this week so that's one stone and two pounds off in total over 13 weeks, nine of which were on 5:2 and the rest on 4:3. Now I've lost the a stone I'm going to take up the suggestion by saf about buying myself something frivolous so I'm ordering a bottle of Bombay Sapphire in my online food order later which should last for the summer. So that's great.

But a milestone was reached this week because I'm now at my lowest ever adult weight (I used to do Weightwatchers and kept off most of the weight I lost but always had a problem shifting the last two stones). I'm astounded that I'm here at a weight I haven't seen since 1987! I'm even more staggered that it's been so fairly effortless which wasn't the case with other weight loss plans I've tried. I'm loving this WOL and how much energy I have and how it fits so easily into my life. As a carb and sugar addict I was resigned to being porky my whole life but now I know I don't have to be and nor does anyone else. We can all do this! It's a hell of a good feeling. I think what's even better is the feeling of knowing my appetite has been reset as well as my enjoyment of food and drink. I still enjoy eating my favourites but not quite as much as what I once did and my relationship with food has never been healthier. Consequently my self-esteem is rising.

I'm going to lose another ten pounds and see how I feel when that happens. Also planning on doing my first 24 hour fast after feeling inspired by some of you. Only done 16 hour ones so far.

Enjoy your weekends!

Bramblesinafield · 26/04/2013 07:35

Inlovewith chocolate - I had Lso plateaued for four weeks and its moving again. Hurrah,

Well done southeast - it's great hitting these levels!

Prawntoast · 26/04/2013 07:37

Well done on the losses everyone. Another pound bites the dust for me this week. I've notice that my losses have been bigger since I switched back to Tues and Thurs fasting, was doing that at the start and then switched to Mon and Thurs. As I didn't want to fast on Easter Monday I moved back to Tues and have had better losses so will be sticking with that. Still toying with the idea of a 36 hr fast but I'm so hungry by the 22-24 hour point I'm not sure I could sleep!

catsrus · 26/04/2013 07:41

Morning all

Just a well done to all of you getting though the first few fasts - and yes, respect to anyone who has done the whole "no food at all" fasts straight off! I never managed that until about 6 months in as I needed milk in my tea Smile. The crucial thing is do whatever version of this you find easiest - and that will change as you do it.

I've been on maintenance for the last few months, having lost 32lbs (was one of the originals way back in August ) and am learning how much I can vary this and still manage to get back down to 9.2 within a week or so of a few very OTT eating days. I never now feel out of control of my eating and weight. It's brilliant !

ELR · 26/04/2013 08:13

bsss did you make it, did you make it??

postmanpatscat · 26/04/2013 08:27

Morning all

Some great losses there southeast inlove and prawn

My post-fast gain has gone, taking another 100g with it, so only 200g up on my lowest weight so far (and 1.4kg from target).

I woke up this morning to find all three of our pet hamsters dead Sad can't bear to tell the kids yet.

BsshBossh · 26/04/2013 08:27

Morning ELR. Yes I made it. My second zero calorie 36 hour fast and to be honest it was a breeze. I can see this will be part of my fasting routine now. It was especially helpful being on the 36 hour fast thread on the 5:2 Fast Diet forum because there were a bunch of us on there fasting at the same time. The mutual support was terrific and I highly recommend that thread if any of you want to try 36 hours instead of 24 hours.

The best news though is that I reached my target weight this morning. 65 lbs lost since early last year. So now I need to start thinking about maintaining (and join the 5:2/6:1 maintainers' thread on here Grin).

Whitecat · 26/04/2013 08:28

Inlove and Brambles what fantastic patience and results you've had. Bet you're both really chuffed you stuck with it.

Dotty342kids · 26/04/2013 08:34

Some really inspiring posts by various long termers and more new people this morning - great to read, thank you all! Especially those who have plateaued and then managed to carry on losing - there's hope for me yet Grin
fasted yesterday and am back to 11st 1 after my four pound birthday related gain this weekend so I'm very pleased about that.
Might do 4:3 next week to chivvy things on a little bit!

swallowedAfly · 26/04/2013 08:39

hi - just popping into say i haven't disappeared but have been a bit meh this week after no loss after my fast on monday and feeling hungry for crap all the time this week. just haven't been feeling it.

am going to attempt a zero fast today to try and claw back from some of the weight i'm bound to have put on today.

hope everyone is ok - haven't had time to catch up yet i'm afraid.

BetsyVanBell · 26/04/2013 08:42

Lots of happy news on the thread this morning - well done everyone!

I had an absolute fast fail yesterday but no matter. I've already breakfast so today won't be one either! Had an absolute low weight recording yesterday so (a) I was probably too hungry to fast (b) I almost always relax when I see a low scale reading!

Really must stop eating sugary things - I've turned into a demon since I had those ice creams the other day Blush.

headintheclouds · 26/04/2013 08:54

Woo hoo, after a 3 week stand off from my fat bits.. Finally I'm back down to my pre blip of 10 st 7 lbs,. Next goal is to get into the nines
