Fasting / 5:2 diet

Talk about intermittent fasting and 5:2, including what’s worked for others. Mumsnet hasn't checked the qualifications of anyone posting here. You may wish to speak to a medical professional before starting any diet.

The 5:2 thread number 25- One year on from Dr Mosley's Horizon ep!

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.

NFD = Non fast day

NSV = Non scale victory

Michael Mosley has a website to accompany his 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:

All our previous threads can be found by browsing through our very own fasting section of the site.

Another thread which breadandwine has started is a good resource for some of the tips and links 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. 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.

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

monster54 thanks for the reply re the back pain & kidneys....yes I reckon I do clock up around 2l most days....
Is it a bad thing they're hurting like that each FD? Seems a bit worrying!

Breadandwine · 10/08/2013 01:43

Thanks, folks!

berri I've had a look on the 52fastdiet forum - always a good place to check for info - and I found this thread on back pain and fasting:

HTH! B&W

wildwater · 10/08/2013 02:08

Don't worry sAf - you will get back to it. We know it's a long term strategy, not a short term fix.

thinkcan · 10/08/2013 04:51

funnyfishface Sounds like you have haven't had an encouraging start. Please don't give up yet - this WOE sometimes does take a while to show the results. I have been on a weight plateau for a while, so am focusing on my nsv's like smaller clothes size, less drowsiness during the day and most encouraging of all, the feeling of better control over food issues. I'd really like to get down to 110 lbs by the time dd comes home from uni for Christmas. She needs to lose at least 20 lbs having put on a lot of weight since going to uni 2 years ago. She has seen me go through too many failed diets to believe what I am doing now will work this time. I want to give her a big surprise when she sees me next.

frenchfancy · 10/08/2013 06:49

hellesbelles I have a physical job, and have no problems fasting. I actually prefer to fast on days when I am physically active rather than days when I am on the computer.

JB30 · 10/08/2013 07:05

Awake since 5.30am, and little visitor at 6am put paid to any chance of sleep. I'm pondering whether I should attempt a 16:8 today, although it seems unlikely at this point I can last til 1pm. On the other hand, was a major piggy guts last night and the night before due to raging hormones. The nice thing about doing a 16:8 is it saves me a few hundred cals which I eat at the end of the day, wrapped up in purple paper
Too cute - my dd4 is trying to do a word search, bless, can't read but giving it a shot! Face is creased in concentration

JB30 · 10/08/2013 07:18

To clarify, I'm not wrapped in purple paper Blush

MissStrawberry · 10/08/2013 08:25

mttum - great weight loss! Have a lovely holiday Smile.

Grin

Thank you vintager52er Flowers

GrinGrinGrinGrin

End of first week - 4lbs lost Shock. I think half is down to TOTM and the other to 5:2 but I will take it. Now exactly 12 stone and very very happy as I can feel I have already changed my attitude to food and eating and after nearly 30 years of feeling it I am not longer scared of food.

Got to go out now for a bit but Flowers and thank you to all for such a lovely week of help and welcome. I couldn't have done it without you.

Imolotmar41 · 10/08/2013 08:32

Newbie here, have been reading this thread for a few weeks and have been doing the 5:2 for about ?6 weeks...I wanted to lose just over half a stone after weighing myself and finding I was 10stone (am 5ft 4) even though I was running twice a week . So I've not lost an ounce since starting 5:2 BUT I feel slimmer, clothes fit better , girls at work say I've lost weight - how can that be? I'm trying not to be disheartened about lack of weight loss as I'm loving the new WOE and focusing on health benefits and has changed my attitude to hunger and fullness , snacking etc. Just looking for reassurance and encouragement ...!

swallowedAfly · 10/08/2013 09:13

i am so far off the wagon it's ridiculous. been having binge like days and all sorts.

i also realised that i'm not getting anywhere near as much exercise during the holidays as i'm not doing my epic walks to work and back.

i'm just trying for damage limitation at the minute but can't really see me getting back into it properly till the holidays are over.

someone kick me.

JB30 · 10/08/2013 09:15

Stupid question, weighing yourself on the same scales? Same time of day/same clothes. Maybe you increased muscle mass and decreased body fat, although I don't know if running does that as much as weights? I run very slowly and have found my waist is narrowing quite a lot, even though my weight loss is only about 10 pounds, not saying "only" as in not happy, v pleased its the most I'v consistently lost and kept off in months.
Or you could step in it tomorrow and see whoosh, 5 pound gone. Scales are instruments of torture, numbers don't matter, clothes are a better measure. Total hypocrite btw, I'm on/off mine like a nutter Blush

Dotty342kids · 10/08/2013 09:22

Aw, well said breadandwine I love all the helpful advice and watching the "newbies" become old hands and start to dish out the advice too Smile
Missstrawberry that's great news after your very trying week - well done!

SAF I won't kick you, that seems a little harsh but i will say this! Just get through the hols as best you can, try to 16:8 for damage limitation where you can and if you're still misbehaving when the kids are back in school I'll be at the front of the line with my kicking boot firmly planted at your backside Grin

swallowedAfly · 10/08/2013 09:24

thanks dotty.

MissStrawberry · 10/08/2013 11:31

sAf - no kicking. Tell yourself you enjoyed the food but now you are going back to what you know you can do and are not going to undo all the good work that has gone before.

Breadandwine · 10/08/2013 12:04

Why Exercise? or Exercise Is Dangerous to Your Diet

Interesting thread here about the effects of exercise and weight loss.

www.52fastdiet.co.uk/5-2-diet-chat-f6/topic6543.html

I've put the link on the Tips and Links thread.

swallowedAfly · 10/08/2013 13:45

interesting read B&W. always amazes me that you can do like an hour at the gym and have only burnt the equivalent of a couple of biscuits worth of calories and are starving hungry to boot Grin

but there was a good comment underneath from someone who pointed out that once that first month of no weight loss etc that they'd expected had passed they started losing weight more quickly because they had more muscle (which ups your bmr) and they felt fit and healthy.

guess the message is if you're going to take up exercise and diet at the same time expect to not see anything on the scales for a while but pay attention to your how your body looks and feels instead.

berri · 10/08/2013 13:50

Thanks for the link about the back pain B&W I think I'll have to really make an effort to make sure I'm drinking enough. Maybe replace some of the green tea with water - although that shouldn't make a difference really should it....?

postmanpatscat · 10/08/2013 13:55

imalot I started with exactly the same stats as you back in Feb. I set myself a target of 8st 10 and reached it in May. What worked for me was using MFP religiously, using exercise to top up the weekly deficit, eating out/indulging about once a week. As a non-drinker, I did not drink any of my limited calories yet did not feel deprived. I know that would be more difficult for some. Good luck!

Talkinpeace · 10/08/2013 15:15

MrsArch Well done on that stone. It will be worth making a teeny bit more effort on the NFDs - if nothing else because when you are lighter, your TDEE will be less.

imalot Its horribly obvious once you find out. And rather call.
You have become denser.
Basically you have stopped carrying excess fluid and undigested food around in your system.
Your fat cells are shrinking as they lose newly forming fat and your digestive tract and stomach are becoming narrower - hence the waist drop
AS you carry on - particularly if you exercise on fast days - your body will start to call on reserves by burning up stored fat and the weight will start to come off

BUT
and I think this is why people plateau
you have to adjust your TDEE downwards with every pound you lose
start eating like the thin person you will be
as that way you'll be used to those portion sizes and stay that way.

Also TDEE drops with age (sadly)

Lizzabadger · 10/08/2013 18:49

Well done mttum, MissStrawb, MrsArch and Imolot.

EagleRiderDirk · 10/08/2013 20:22

^happy birthday to me
I've had cake and will have Wine or three

That one's for the mumsnet poetry lovers Wink

MissStrawberry · 10/08/2013 20:40

Happy Birthday EagleRiderDirk!

I was meant to be having a normal day but have only had 675 calories Confused. That is a week in and already used to potentially less food as didn't calorie count before. Eating when hungry. Stopping when full. Who knew that would be so easy once your head is in the right place.

missS if your appetite reduces make sure you eat enough to be well nourished. Try high calorie foods like nuts, cheese and avocado that won't fill you up too much.
