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!

Morning all. Fast day today, I expect it is for many if us. Monday seems cleansing after a weekend of excess (far, far too much in my case!).
I've got a packed lunch box full of leaves (salad, not random garden stuff!) for lunch, 4 cups of proper tea and an innocent veg pot for dinner.
My danger time is after school, so I've got some hoovering planned to keep me busy.
Good luck everyone.

swallowedAfly · 18/03/2013 07:17

hotpanda it sounds like a fever to me so i'd guess at coincidental coming down with something. the human race would not have survived long if having a low calorie day could induce such symptoms. i could be wrong but i'd take some paracetamol if i were you and treat that fever and headache.

postmanpatscat · 18/03/2013 07:22

Morning :)

Fasted yesterday and burned off more calories than I ate, yet this morning my weight has gone up! How does that work?!

storminabuttercup · 18/03/2013 07:23

Morning fasters!

Today is an extra unplanned fast for me, I'm on week three and feel like I could benefit from it, I'm also looking forward to it!

Like others have said, it's great knowing that you can compensate from eating too much by adding a fast. I last ate at 9pm and I plan on going until 6 ish tonight, I've made a low fat ragu and plan on having a small amount of pasta.

It will be the first time I've done two fasts in a row, tomorrow is my normal fast day, but I'm on a course tomorrow which will keep me busy and I rarely eat at work anyway.

Good look to all the fasters today. Grin

TheHumancatapult · 18/03/2013 07:24

French

No I meant 11am Sunday through to 6am today . Feel fine

TheHumancatapult · 18/03/2013 07:26

Will keep lunch/dinner total below 400 as ate 100 calories on breakfast . Would that then count as fast day ?

postmanpatscat · 18/03/2013 07:26

catsrus well done on your 30lbs!

TheHumancatapult · 18/03/2013 07:27

Then eat normal on Tuesday ? I' like loose another 7lb but happy to do slowly now

frenchfancy · 18/03/2013 07:40

Humancatapult Yes definitely eat normally on Tuesday. And I would suggest Wednesday as well. I think you need to have a decent period of eating normally to get the on/off message through.

BetsyVanBell · 18/03/2013 07:40

HTC it sounds like you fasted yesterday already!

akarucker · 18/03/2013 07:45

frenchfancy that's a great post. Hopefully that will help clear some things up for people just starting.

akarucker · 18/03/2013 07:53

I'm one of those who tries to go until late afternoon before eating on my fast day, for fear of triggering my 'hunger' senses and/or getting the benefits of a longer fast. However, it just occurred to me, as I sit here sipping my morning tea, that perhaps I'm negating that by having milk in my tea when I wake up. I mean, milk is calories, so perhaps that should go also, until I break the fast at about 2pm? What do you think?

swallowedAfly · 18/03/2013 07:57

you already fasted HTC. idea is 500cals between getting up on one day and going to bed the same day. it sounds like you fasted yesterday and are fasting today as well. i last ate yesterday evening at about 8pm. today is a fast day for me so i can't eat more than 500cals till i go to bed. that's it.

either eat normally today or keep fasting today and count it as two days done.

usual story for me of aiming not to eat till at least 4 but hopefully more like 6pm then no doubt some baked bean based concoction to let me go to bed on a full tummy and be assured a bowel movement in the morning.

Chocupid · 18/03/2013 08:00

akarucker I'm exactly the same, I drink herbal tea and tons of it on a fast day and have just realised that there's about 5 cals per cup.

So should we be just drinking water till our dinner? Confused

Meanwhile another fast day for me today as I've been away and unable to do one for 5 days, definitely need a good one today!

Wishihadabs · 18/03/2013 08:01

Hello fellow fasters. Fasted Friday and today then probably Thursday. I have settled into a fast pattern of coffee in the morning, a single meal of about 250 kcal at 2-3pm. Then a light snack about 8. Weighed myself on Thursday lost 1lb and 1.5inches from waist. Went out on Saturday and was told I was looking slimmer also got in to a top I last wore in 2005 - result. Good luck to all the Monday fasters . :)

frenchfancy · 18/03/2013 08:01

OK I've just skim read the Eat Stop Eat book and now understand a little more about the confusion between a 24 hour period fast and a one day fast.

Eat Stop Eat: Eat NOTHING for a 24 hour period (any 24 hrs) then eat normally. Repeat twice a week.

5:2: Eat 500 cals for 2 non consecutive calendar days.

Many of us are doing both together ie eating nothing for 24 hours then eating the 500 cals before going to bed.

What you shouldn't do is assume that you can eat stop eat and include the 500 cals. That isn't fasting.

swallowedAfly · 18/03/2013 08:19

when i tried the eat, stop, eat method i didn't get as good results - though admittedly only did it for a week. i get best results from doing two fast days of 500cals and doing every weekday (including the 2 fast days) only eating in a small window of between say 4 and 8pm.

technically i guess i'm combining 5:2 with something like fast5. when i get to my goal weight i can work out how to maintain. it may be that i can maintain purely by the fast5 (only eat in a small window) method or it may be i still need fast days or fast5 can be my staple with a fast day thrown in if weight starts going up.

lots of ways of doing this really.

akarucker · 18/03/2013 08:20

chocupid there are calories in herbal tea??? Oh no, I thought they were calorie free!! I get through about 10 cups a day!!!

BetsyVanBell · 18/03/2013 08:33

The calories in non milk teas are negligible, please don't worry about them folks! We're talking zero to 2 calories.

The milk in tea debate pops up quite frequently. If you can go without milk go for it but if you can't don't consider it breaking your fast but do count the calories towards your 500/600. If not being able to drink a proper cup of tea or coffee in the morning is a deal breaker for this WOE then I think it's better to have the tiny bit of milk than to not do the fasting at all. Your digestive system is still going to be having a good break compared to a normal day of eating.

Some days I can manage on just herbal teas, sometimes not, yet I'm still losing weight and still reaping the health benefits Smile.

Chocupid · 18/03/2013 08:36

akarucker yes I'm shocked too!
just checked in the tea I drink a black herb tea there's 5cals a serving.

But in peppermint tea 2cals per cup and ordinary decaf tea says 1cal per cup
so it looks like I either count the calories in my normal drink or swap to the decaf and drink it black. Sad

Any opinions as I need my tea!

Chocupid · 18/03/2013 08:39

Sorry cross posted

Thanks Bvb

akarucker · 18/03/2013 08:51

Well, compared to the chocolate bar I used to have for breakfast, those 5 cals are looking pretty good for me right now!

catsrus · 18/03/2013 09:37

Please don't get obsessed by the odd calorie in herbal tea or milk in normal tea/coffee!

This is not a calorie counting diet. The calorie figures are guides not rules. Dr M says there is nothing "magic" about 500 - it just seemed a good compromise as totally without food for a day is hard.

I have not counted calories - I know I have gone over 500 on lots of occasions and I have still lost 30lb. I usually have milk in my tea in the morning (though. Have now found lady grey tea which I like black) I would not have been able to do this WOE if I couldn't have my tea with milk first thing Grin.

Keep it simple.
On 2 non consecutive days eat only a small amount of calories
The rest of the time eat sensibly.
Have occasional blow outs and treats, but if you have too many you might need to introduce a third fast day to compensate.

Learn to be 'mindful' - become aware of what you eat.

Eat real food.

Many of us who have been doing this for months have found it really does become easier and we are now in control of our food and our weight. But again, at the start

Keep it simple!

catsrus · 18/03/2013 09:41

To sum it up

We're not on a diet we're learning to regulate our food intake and also get the health benefits of fasting.

Simples Grin

Chocupid · 18/03/2013 10:00

Thanks for info, I have been doing this for nearly 2 months and am having a plateau so was just trying to be a little stricter to get things moving again, but happy so far as I've now lost nearly a stone.

Think we get carried away with the fast weight loss initially and the fact it seems to good to be true, but as someone pointed out on the fast diet thread, average weight loss on this WOE at 1lb a week, which can be done on any diet it's just this is more sustainable and with thrown in health benefits.
