Fasting / 5:2 diet

5:2 Diet Thread: Part Three. Come join us!

The continuing thread for those of us following either the 5:2 diet or the alternate-day fasting diet. Both are two versions of Intermittent Fasting, which you can read more about here.

The 5:2 diet was featured on Horizon recently, and essentially requires you to fast for 2 non-consecutive days per week. The other 5 days, you can eat what you like. 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, on those days.

Here is a list of the links we've gathered so far about this diet. I hope I haven't left many out, but it was a 40 page thread! This is a good start for anyone, though:

First things first, here is a link to our previous thread, which we've outgrown. Lots of good support and ideas still to be found there.

Here is the link to the BBC article regarding Michael Mosley's findings, which was featured on Horizon.

is a link to the first part of the aforementioned Horizon, subsequent parts of that episode are linked on that page.

There is a Wiki article here which explains intermittent fasting and gives a short summary of some studies which have been done on it.

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.

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%).")

Important link 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.

And for those already fasting, here is a link to 100 snacks under 100 calories. :)

Another food link, here is a link to the BBC Goof Food site, with a list of low-calorie soups.

I will start a different thread just for recipe links, though, as there seems to be some demand for that.

A BIG THANK YOU to all who have been contributing, btw. Most of us are new to this diet. All of the links above have been posted by others in our previous thread, 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 them all in one post this afternoon. Wink

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

Oh sorry thought I had made it clear but didn't - I have no intention of fasting while pregnant! :) I think it would be stupid and dangerous, especially because I developed gestational diabetes a few weeks ago. I'm managing blood sugar through diet alone but my now high risk of type 2 diabetes in later life has made me interested in diet generally. I've been overweight for years and feel like it's the right time to make some changes, when I have a year off work on maternity leave.

First month or two when baby arrives I'll just be trying to survive tbh and hoping to breast feed and lose some weight that way. After that I am definitely open to trying this way of life, if I can figure out how to make it work. If still breast feeding I would presumably need to eat more calories - maybe 1000 a day on fast days, split into two meals? I think I read before it's not good to release too much stored fat when breast feeding due to toxins tied up in body fat?

Ahhh just been invited for picnic tomorrow with friends. Not wanting to tell them about the diet. Need fasting lunch that doesn't look too inadequate. I have some salad and fruit. What can I add to it? Needs to be obtainable at convienience store. Something I can give to ds (2) too but bulk up a bit for him. 150 cal or so. All I can see in fridge is cheese + bacon!

Angelico - I bf and I have just been doing the fasting normally. That way the bf is actually helping me to lose weight. You put on fat stores in pregnancy in order to use them up as fuel while bf - so if you're eating extra to cover your bf energy needs, you're not going to be using up the fat stores you laid down in pregnancy for it.

First 2 weeks I lost 4lbs a wk, the following 2 weeks I lost 3lbs a week. This week I did lose 3lb weighing after my last fast day on Friday, but I have put 1lb back on being a bit indulgent this weekend. So 1st 2lb in 5 weeks, still a fab loss, but 2lb a week is a bit disappointing in terms of how long it's going to take for me to lose the rest of the weight, so might try a bit harder next week. I wouldn't mind doing 6:1 or something long-term, but I really don't want to be doing 4:3 for too long, especially being careful on feed days too. I hate diets! I suppose it was a bit optimistic maybe to think the weight loss would remain at the same rate.

Ah. Well, same things probably apply.

Go with the flow. Don't collapse. Just do what feels best. I didn't/couldn't eat at all during pregnancy but babies were huge. They do get what they need.

Obv eating 400 cals of grot during any stage of life isn't good. Quality not quantity, I s'pose

Hi,

Please can I join, you've all really inspired me.

Going to do my first fast tomorrow but am a little confused. Had my tea tonight about 8ish and know I can have 500cals tomorrow. But at which point do I break my fast? Tomorrow at 8pm or the morning after?

TIA

Fast day for me today. I was a bit hungrier than before but I think that was because I was home with the children and getting food for them. It went ok though.

ChazsGoldAttitude · 09/09/2012 21:05

UglyBetty

What most of us seem to be doing is eating one or two meals during the fast day that total 500 cals then not eating again until the next morning. So I did
Sat dinner 8.30pm
Sun lunch 1.30pm - 300 cals
Sun supper 8pm -200 cals
I will next eat at breakfast tomorrow which is a normal day.

UglyBettyIsMyHotterSister · 09/09/2012 21:09

Thanks Chazs.

Is it ok not to eat at all until teatime tomorrow and have the 500 cals in one go? Obviously I'll drink water (and the odd brew)

rachelblythe · 09/09/2012 21:16

Uglybetty- yes that would be absolutely fine. Some people would even say that would even be most optimal, as you are fasting for a really extended period. Gord luck. I have one meal at around 2pm.

fast day one - it's 1:30pm so half way through. Was doing fine until I had 100cals of fruit at lunchtime (kids birthday party picnic) and now I'm starving and can't think of anything else!!!

WWYD? eat more cals now or wait til "dinnertime"?

RightBuggerforGOLD · 09/09/2012 21:42

Mousey - personally I would have eaten more if hungry and then accepted that was it for the day, but I know a lot of people prefer to eat as late as possible.V

GirlWithTheMouseyHair · 09/09/2012 21:48

Thanks - might then eat more now to see me through the rest of the day. Then I'll easily be doing the second 16hours til breakfast tomorrow anyway.

Hmmm, have to hunt around for 400cals worth of food!!

Adding to the fasting/pregnancy/breastfeeding conversation, I'm in the final tailing off stage of BF now (DD prob has 1 feed every 24hours ish, sometimes in the middle of the night, sometimes it's when she wakes - depending how the night's gone - sometimes it's more a mid afternoon snack). I def couldn't have done this before, I've spent the last 9months absolutely ravenous all the time, but my appetite has naturally decreased as BF has in the last month

GirlWithTheMouseyHair · 09/09/2012 21:49

can I double check, I know there's a bit of a debate around milk in tea and coffee, but having tea and coffee generally, is that breaking the fast or no? Do you count it in your calories? Managed to have my coffee black with no sugar but can't abide no milk in tea!

Generally people seem to be agreeing that milk in drinks doesn't break the fast, but I definitely count milk within the 500 cals. I usually use around 100 cals milk, then the other 400 food. Today is the end of week four for me. Done 13 fasts so far. Weight fluctuates a bit depending on if I weigh after a feed it fast day, but I would say I have lost about 9lb. Two days of feeds in a row this weekend, looking forward to a fast day tomorrow.

Just went out to Zizzis tonight with DH wbo's also on the fasting diet. Todays a normal day but neither of us could finish our meals (v v unusual) I ate a third of my superfood salad after a starter, but would normally have polished it off and had pudding.

So it definitely seems to be telling our bodies that we're full a lot earlier than usual.

Hi everyone. Fast day for me on Sunday. I ate an oatabix with milk for breakfast (well eaten at 2pm) and than beetroot and scrambled eggs for dinner.

I thought this article was interesting (from a guy that does fasting himself)

Hi all I had to wiggle my fasting around last week, but am back on a Sunday fast again. It seemed to go Pretty well. Next fast will be Weds and will weigh in then. I hope to have lost something?!
Just had a slice of pizza after midnight, so that's definitely the end of that fasting period then! Blush

This way of eating really does affect your appetite. On Saturday night I was a bit despondent as I thought I had eaten a really big tea, but when I looked at how much was left in the dish I realised I had only eaten half of what I would have normally eaten and not had the 2 pieces of bread I usually had with it. Last night it got to about 8pm and when I realised I hadn't eaten anything for an evening meal. Just not hungry. On previous diets I would spend hours obsessing on what i could eat on treat days but as I can eat normally it just doesn't occur to me now. Fasting day today and it does not bother me in the slightest. DP has been amazed at how well I have done and my attitude towards eating (he has seen me crash and burn on many a faddy diet) so he is going to start eating this way with me from Friday (he has exams this week so thought it might be a bit much to start until these are over).

Thanks for the link rosemary interesting reading. I've always argued that breakft made me hungry and started me overeating but was always shouted down by the must have breakfast bunch who insisted my hunger was my metabolism being kicked into action.

I'm fasting today, I had given up last week but ive got drawn back in....mentally I feel more able for it.

Fasting today. I had a cup of tea (with milk!) an hour ago. Flipping starving now which I don't recall on either of last week's fast days. Off for a nice distracting shower and hopefully it'll pass.

Today is my first day on the 5:2 diet after deciding I really need to shift this last stone of baby weight before my DS's second birthday in November. I think yesterday I psychologically cut down on food as I knew this was approaching so the result is I am now starving. Aiming to get to 1pm or later for my first meal so must keep busy!

Thanks for this thread, it's so helpful and good to know there is so much support out there.
