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!

Hi all Smile

It's my second fast day tomorrow, and just wanted to ask if Marmite in hot water would be classed as a drink or food?

Would it break my fast if I had some early in the day when I don't plan to have my 500cals until 7pm?

Sorry if it's a stupid question Blush still trying to get my head around it all . Thanks.

Southeastdweller · 24/04/2013 20:26

mrschambers and everyone else having a prolonged period of plateauing Time now to do something different. Apart from what the others have said, some other kick starts could be to do consecutive days or 4:3 for a week or two.

salty Yes know totally what you mean. I checked out the new sparkling Greggs at St Paul's today at lunchtime and wasn't interested at all in any of the cakes or biscuits. I did however have a tasty egg and tomato roll which was only 320 calories (they don't use mayo). Went to Caffe Nero for my daily Americano where the quality of their sweet stuff is better than Greggs and wasn't interested in any of that either even though they've gt new cakes in. I always thought I 'had to' have something sweet after my lunchtime sandwich but realised for the very first time today that actually I don't have to - the coffee and egg roll was enough.

akarucker · 24/04/2013 20:30

Urgh, don't you hate it when you've wasted an eat day on eating boring, crap food. I'm pretty sure I've stayed in my TDEE, but given how much I now appreciate food, I wish I'd had nicer stuff. This woe has definitely changed the way I appreciate every mouthful. My taste buds are super alert and good food tastes wonderful! I'm slowly being trained to not mindlessly stuff my food, but concentrate and enjoy. That's probably why it's annoying that I didn't do that today.

MelanieCheeks · 24/04/2013 20:38

Does marmite count as breaking your fast? I don't know. I've never tried to do a total no-calories for a long time approach. And I remain to be convinced that it has any benefits.

Just remember that EVERYTHING apart from plain water has calories - even black coffee,tea, herbal teas etc. It might just be 1 or 2 calories, but I have no idea how uber-strict you would need to be to call it a "proper" fast.

ceebeegeebies · 24/04/2013 20:45

Desperate - I too am amazed at how I can manage without food Smile I have always snacked and eaten at the first sign of hunger (hence why I am overweight Wink ) so it has been a revelation that hunger pangs are not the enemy.

perversely I also find my willpower is greater on fast days...it seems that I can say no to stuff much easier when I know I can't have it rather than on days when I used to calorie count and I always used to think a few extra calories won't do any harm!

anyway have been out for 2 meals today so not a great eating day but have not snacked at all and the food has tasted delicious...however I am looking forward to a fast day tomorrow which I never thought I would.

Itsaboatjack · 24/04/2013 21:27

Evening all. Weighed this morning at 11.7. Frustrating as I was at a low of 11.5.2 three weeks ago. I thought after a zero calorie fast yesterday it would be closer to that. Had a good eating day today though, I have had about 1800 cals, TDEE is 2100.

Think I'll go for a run tomorrow too, I haven't been for a week and a half as I've been full of cold.

fluffypillow not a silly question but I don't know the answer I'm afraid. I try not to have any calories at all until I break my fast, just water and black coffee. But if I really want a cup of tea with milk or a boullion drink then I will without too much worry.

Btw if anyone is interested Tesco (at least my local one anyway) have an offer on innocent veg pots for £2, usually £3.90. Does anyone know if you can freeze them? I may bulk buy some.

akarucker · 24/04/2013 21:36

itsa don't know what it says on the box, but I always freeze the innocent veg pots and they're fine.

BetsyVanBell · 24/04/2013 21:37

fluffypillow I'd count the calories but I wouldn't count it as breaking my fast :) I'm not very purist about it though - if I need a cup of tea with milk on my fast day then I'll have it. Seems to be working ok for me Grin

Southeastdweller · 24/04/2013 21:37

Thanks for that Tesco tip itsaboatjack. Did you enjoy your meal at Itsu? I can't get enough of their miso soups (108 calories). Much tastier than the one they sell at Pret. It's crazy they haven't expanded beyond London yet.

BetsyVanBell · 24/04/2013 21:50

So y'know that sugar-free thing I was doing? Umm well, I may have ended up eating not one but two mars bar ice creams today Blush. I wouldn't normally, DC picked out a multipack and I thought what the heck it is an eat day after all (only 130 cals each Hmm ). And this is why I normally choose the ice creams/treats for the kids - there's plenty of stuff I can fill the freezer/cupboards with and not give a second thought to but I'm a sucker for anything involving caramel, with chocolate and ice cream, ideally with some praline too...

If I'm grumpy in the morning I'll know why and it'll be my own fault, no one else to blame (etc). sigh

Itsaboatjack · 24/04/2013 23:32

Thanks aka I'll definitely get some then and fill up the freezer.

SEdweller I love Itsu. I had the poached salad salad, and I love the chocolate covered edame beans makes you feel like you're being healthy even when you're not.

bvb I can't resist salted caramel icecream, it's my weakness. There's no way I could have any in the house and not eat it.

melodyangel · 25/04/2013 00:02

DesperateDietingHousewife Are you prone to anemia? I have to be very careful to keep up my intake of iron, so lots of leafy green veg on fast days and I take an iron tablet or multi vitamin/mineral if I'm feeling dizzy.

Tea and biscuits in the evening is my main weakness.

peplum41 · 25/04/2013 02:12

Hello all, and welcome all new fasters. There are so many, its hard to remember all the names, but keep chiming in and soon your name becomes familiar. I'm usually at least a day behind the end of the threads, so if you've asked a question its already been answered by the time I turn up.

southeast I shall brave one of the 2 greggs in my tiny town to inspect their tottenham cakes, although I'm not sure if that's just a London thing. More likely to have Lancashire lard arse cake round these parts. And I have no idea what itsu is, but it sounds great. Chocolate covered edamame beans!

akarucker you seem good and positive right now.

Whenever I read these threads I always feel thirsty. And end up reading with a bursting bladder. Must dash.

ELR · 25/04/2013 06:54

Morning everyone! Looking forward to a good fast today! Ad a low cal day yesterday well, 1490 which is 450 under my tdee just as a change as usually eat right into it!
Hoping for a loss tomorrow morning, DH has put me to shame and just popped out to do a quick 5 mile run arrggg!! Don't now how he does it!

Barbie1 · 25/04/2013 07:01

First fast day. Eek!

Did my insanity last night and had my dinner at 8pm, so I'm aiming not to eat until 8lm this evening.

I've been awake most of the night thinking about food Hmm

This is really strange as I'm not really a food person. I don't really enjoy food due to be such a fussy eater Sad I must of subconsciously been thinking about what lies ahead.

BetsyVanBell · 25/04/2013 07:07

Good luck barbie - you know lots of us here don't last 24 hours? It seems a tall order for your first fast! I usually break after 18 and split my cals between 2 meals. Don't forget to drink loads!

MelanieCheeks · 25/04/2013 07:39

Good luck Barbie - for your first few fasts do whatever it takes to get through them, even if that means having a few celery sticks to nibble on, lots of green tea and bouillon on standby.

I'm fasting today - I've been doing this for 3 months now, and my usual is to have an egg for breakfast, miso soup at lunchtime, and tonight I'm thinking of doing a tuna and salsa stuffed mushroom.

Barbie1 · 25/04/2013 07:50

Thank you both Smile

melanie your ideas sound great but I don't eat any of those things Blush t

Barbie1 · 25/04/2013 07:52

Told you I was extremely fussy.

I'd rather go as long as I can manage because the stuff i do eat isn't great Sad if I do break I will reach for the fruit.

Even if all this diet means to me is that I cut down on sugar then it won't be in vain

BsshBossh · 25/04/2013 07:52

Trying my second zero calorie 36 hour fast today. Have a good plan for the day (aside from work of course) filled with chores, admin, lunchtime gym and an evening walk. Anyone else doing a complete fast today? I'll be on the 5:2 Fast Diet forum thread as there's quite a few doing a 36 hour fast there today.

Miffytastic · 25/04/2013 09:48

Ooh did a cheeky weigh in this morning, should be tomorrow really but I fasted Mon & Wed this week rather than Thursday or Friday.

Anyway - down to a new low of 10st 2.5 Hurray! It's weird because I did feel that my tummy was smaller (as an apple shape that's where i notice it) but having done a WI on Saturday that was 10-4 I thought I was making it up. I have been tracking on MFP and keeping to TDEE for the last few days.

Doubtless I will bounce around this weight for a while but I am celebrating the new low today, and the fact that fasts are done for the week... .and I am still hopeful that 9 stone something is within my grasp!

DesperateDietingHousewife · 25/04/2013 10:05

Hi Melody. I don't think I'm anemic (sp??). I have been seeing a nutritionist who has sorted out a lot of things for me. I will check with her next time I go.

Really weird yesterday-it was my second day of eating normally after fasting on Monday and I felt shaky quite a lot but I noticed it was usually after eating sugar. I didn't feel like that before I started this WoE. I'm being treated for candida and I wonder if fasting on Monday with no sugar at all has made my body even more sensitive to it on normal days. I know what I need to do-give up sugar-one step at a time though!

Am fasting today and going to try and go to tomorrow morning with no solid food, just lots of water and liquids. I'm not going to stress if I don't do it. Am just interested to see if I can do it and I want to try and lose a bit more this week. I'll eat if I feel weird, heachachy or shaky. ATM, I feel fine though and have just finished a Jillian Micheal's shred (level 1-nearly killed me-haven't done it for ages!!)

Looking forward to reading eveyone's posts. It's makes for very interesting and inspiring reading!

Barbie, don't know if you have read the book, but they recommend tangerines on this diet (app they have something in them that helps with the fat burning process). I have been eating mandarins as I couldn't find tangerines. I figured they were close enough. Or if you don't like those, remember to eat a fruit that is low GL/GI so it doesn't spike your blood sugar and make you feel more hungry.

Good luck if you are fasting today!

Barbie1 · 25/04/2013 10:41

Tangerines? Yes I like them Grin

Haven't read any book due to currently being in France and not being able to get hold of them.

I'm doing ok, just had really weak no sugar added juice.

If I manage today I will look into getting a book off amazon

melodyangel · 25/04/2013 10:44

Miffytastic Well done that nine stone something is well on it's way!

Barbie I'm not sure I could manage this WOE if I was in France too much temptation!

AlottaReading · 25/04/2013 10:58

Finally did a weigh in today and have lost 3lbs since I started, so 9 days overall. Happy with that.

Since my fast on Tuesday I've not felt hungry, usually I spend evenings going back and forward to kitchen for something to snack on but just realised I didn't do that once last night. Even though there's a load of home made flap jacks and cakes in their too. I have a sweet tooth and normally can't resist the cakes.
