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!

I really need to read your success stories as I am totally losing the will!! Have lost a about a stone but need to loose one more and I just can't shift it. Doing 5:2 and I loose a few pounds after fast days but they just come straight back on; I think I am clearly just eating too much food on my days off. Doing exercise at least four times a week too. It is SO frustrating!!! Going to Greece on hols in june and I need to feel and look better than I do now, feel horrible.

MissRee · 26/04/2013 09:09

Hurrah! Half a stone in 2 weeks Grin

I think this woe is going to suit me down to the ground! I fasted from 8pm Wednesday until 8pm Thursday with only a 350 calorie dinner last night and then nothing until 9am this morning. I feel so good for it!

Dotty342kids · 26/04/2013 09:11

Well done headintheclouds - let's hope it's the start of a new bit of loss, as opposed to staying the same!

BetsyVanBell · 26/04/2013 09:11

biltong Losing a stone sounds great! How long have you been doing IF? I don't know what your eating habits are but something that can help a lot is keeping it healthy during the week (so good nutritious food, no snacks, no booze) but letting go a bit at the weekend. I know aka has had some good weight loss in the week by kicking the sugary snacks and it definitely works for me. It's also worth noting that if you've lost a stone your TDEE will be lower so you don't need to eat as much.

Do you do 5:2? Maybe pop in an extra fast day here and there - sometimes it helps the weight loss along a bit. On the other hand you may have reached a plateau point and you just need to wait it out while your body recalibrates to your new weight, persevere, add a few extra measures and you'll be back on track.

SaltyandSweet · 26/04/2013 09:36

postmanpatscat sorry to hear about the hamsters, poor little guys Sad

Eat day for me, but I think I might do a mini fast - eat only between 2pm and 7pm - just because I don't feel like eating this morning despite a successful fast yesterday so might as well make the most of it. I do intend to eat a small but nice lunch and a yummy dinner so will end up quite satisfied. I am hoping this tack for this week will help shift me downwards as well as allow me to enjoy a few meals out this weekend Smile

monster54 · 26/04/2013 09:53

Urrrgghhhhh a 0.75lb gain this morning. Extremely bloated and crampy this morning so putting it down to TOTM.....

I really hoped to see below 11st 5lb today and I would have been 'normal' BMI not 'overweight'....

Need to stay strong and hope it comes next week.....positive thoughts for me please!!

AliceinSlumberland · 26/04/2013 10:30

Had a great fast yesterday, wasn't even feeling too hungry or affected by it which was great as my fast on Monday was really hard. However went to my friends for tea and definitely went over 500 cals!! So fasting again today to make up for it.

Barbie1 · 26/04/2013 10:51

Loving all all of the positive weight loss stories Smile

I didn't sleep well last night Hmm I wasn't hungry or anything but something was keeping me awake.

I feel like I almost don't want to eat today, I can see how this becomes so totally addictive!

Good luck for all of the fasters today.

swallowedAfly · 26/04/2013 10:52

i can appreciate the frustration at being stuck. i've actually gained this week which is a bit gutting.

Dotty342kids · 26/04/2013 10:58

C'mon SAF you can do it!!!!

Breadandwine · 26/04/2013 11:04

Well done on all those losses, folks!

But, for those of you stuck for a while and not losing weight, it's important to remember that this is not a diet! It's a way of life, and weight loss is merely a side effect.

All the time you're practicing IF, even though the scales may not be moving, console yourselves with the thought that all your other health indices will be improving!

And as posters have confirmed this morning - the weight will come off!

Just one caveat - anyone with an underactive thyroid can have problems losing weight. Check out this (one amongst many) thread about this issue on the 52fastdiet forum:

BsshBossh · 26/04/2013 11:20

saf if you're doing a zero fast join the thread at the Fast 5 forum cause there's lots doing it together and I found it very motivating to keep checking in with them on the day:

Not Fast 5, I meant the Fast Diet

MelanieCheeks · 26/04/2013 11:29

No big weight loss this week, but looking at teh long term picture I'm down 10 pounds since Christmas, and very nealy at a healthy bmi.

Plus points I'm focussing on - my clothes feel great, some of them are evn baggy! And my nails have never looked better.

LaurieFairyCake · 26/04/2013 11:35

13 weeks of the 5:2 and 18 pounds lost.

I think it's relevant to say that people experience this way of eating differently. It's made no difference to my sweet and savoury tooth - in fact I relish eating cake every day in a way that I couldn't really before - there's always been a teeny bit of guilt. I have eaten cake every day of the 5 days eating days. Every week I've eaten takeaway fish and chips and mushy peas.

I am still eating lots of healthy foods as I always did but I am also still enjoying all the stuff you're supposed to eat in moderation.

The differences for me are : I struggle to drink wine, gives me a headache/hangover after one glass. I've switched to a couple of bottled beers instead Grin

I have lost my pre-diabetic blood sugar issues. If I didn't eat by lunchtime I'd get shaky, grumpy and feel murderous. I have none of that now even though I don't eat on fast days til 4pm.

I have just scarfed a triple bacon roll and a slice of coffee and walnut cake - and I feel I could take on the world Grin

It's so great to hear all your stories and losses.

Biltongmuncher · 26/04/2013 11:49

Thanks betsy, just back from the gym! Will really try cut out sugar and watch what I eat out of fasting days a little more. I seem to be good on the days I am in work cause I am occupied and then the days at home with the kids are a bit of a snacking disaster! Will keep going and reading this for motivation.

Dotty342kids · 26/04/2013 11:52

That's great to hear Laurie, I too am someone who really enjoys cake and chocolate and have no thoughts of giving up either! I do enjoy them on my feed days but try to ensure that I don't perhaps, have a "junky" tea AND those yummy treats all in the same day. So I enjoy them all, but in a slightly more moderated way Smile

BsshBossh · 26/04/2013 12:12

Laurie I hear you. I've eaten ice cream nearly every day whilst losing weight. I don't like to deprive myself. It's all about balance really.

MelanieCheeks · 26/04/2013 14:42

Oooooh, you and your talk of ice-creams! I went and had a Masr ice cream bar after lunch. Hadn't had one in ages! It's pretty decent as a treat - 130 calories, compared to Magnums and the like at well over 200.

systemsaddict · 26/04/2013 14:53

So I've been doing this about 6 weeks now and have just had my first 2 days of weights with a BMI under 30 which was my first big goal Grin. Next goal is for my weighted mean average BMI to be under 30, which by the chart will be next week sometime. Losing 0.67 pounds a week on average - that may sound slow but I'm doing this the easiest way possible and not tracking TDEEs on my off days, I'm in no rush - this is working so well I'm now an 'in it for life' person now!

BsshBossh · 26/04/2013 14:59

Melanie thanks for the tip about the calories in Mars ice cream. Will add that to my online order :)

ceebeegeebies · 26/04/2013 15:36

Laurie so glad you have posted as it is interesting to see that others aren't losing their sweet tooth as well Wink I am a sugar addict and, tbh, I am comfortable with that and not really prepared to give sugar up which is the main reason why this diet appeals to me so much Grin

I am not being particularly careful on my non-fast days but with a TDEE of 2500, I have quite a bit of slack anyway to indulge on those days...and I am doing! And it is such a good feeling to be able to do so guilt-free - if I want cake, then I am bloody well having cake!!

Having said that, I think I may just have had all 2500 calories in one meal as DH has just taken me out for lunch (it is my birthday tomorrow and we were taking advantage of the DC being at school/nursery) and I may have had 3 courses plus wine!!

Have just completed week 2 and I do feel the diet is working. I don't have any scales so can't weigh myself and don't really want to either - but my clothes are fitting just that little bit better so I am sure it is going in the right direction.

LaurieFairyCake · 26/04/2013 16:05

Crunchie Blast ice cream Lolly is only 120 calories. Really yummy Smile

BetsyVanBell · 26/04/2013 16:21

bsssh Melanie* - calories on those mars ices are good - only thing is they come in packs of six... then they call to me from the freezer!

tougholdbird · 26/04/2013 16:27

. I have been following this WOE since Feb and have lost 19lbs and hit 9 something for first time in sooo many years this morning. No way I would have done it without the inspiration and wise words of these threads.
