5:2 Diet Thread: Part Four! Sit down, have a cuppa..

GreenEggsAndNichts · 20/09/2012 22:36

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 thread before that..

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.

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.

We often mention basal metabolic rate (BMR) here. This refers to the amount of energy (calories) a person uses when at rest; so, the basic number of calories a person needs to stay the same weight. This number is often quoted as being 2000 calories for the "average" woman, but of course is different depending on how tall you are, how much you weigh, etc. Here is a calculator which will easily help you to find out what your BMR is.

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!

Marking place.

Have had a weekend at home, with DF and DB/DSIL, which has led to all manner of bad behaviour. Tomorrow will be my next fast day. I'm going for IF which means missing breakfast. Not sure how many days will be realistic.

TalkinPeace2 · 23/09/2012 22:43

Party last night.
Quiet (hungover) day today.
Fast tomorrow.

worldcitizen · 23/09/2012 22:45

Thanks to everyone lots of info and feedback and helping out here on this thread. I am getting myself ready and prepared. Due to joining this thread I have not even eaten cake today like I usually do on Sundays, simply cause I wasn't in the mood.
I will look if I can find these recommended Workout DVD's in the library tomorrow.
I am also going to bed soon, as I keep reading that lack of sleep and sleep interruptions and not having a regular sleep-wake cycle has a lot to do with gaining weight or having trouble shifting the weight etc.

I also will start looking at all these soup and veggie recipes. Thankfully I really love soups, stews, and all sorts of vegetables and salads. I think preparing soups and stews is great for colder days, where I appreciate hearty and savoury food Smile
Thanks everyone and thanks Laska for the links

frenchfancy · 24/09/2012 06:49

Bit of a pig out yesterday. Mc Ds for lunch - I was quite good as I only ate half my potatoes and didn't have a choc muffin, then Sunday dinner with lots of mash followed by cake and cream.

Will try and be good today, but it is DD3s birthday so there will be cake. I will fast tomorrow.

Still losing weight though, and I love the fact I can eat cake and not feel guilty.

Dosey · 24/09/2012 06:49

Morning I had a fast day yesterday and did very well. I managed to go until 2pm before I had an apple. Then for tea u had a bagel and cheese and was still within my 500 calories. I feel great today and looking forward to a healthy eating day.

I have lost 13lbs in six weeks which I am very pleased with. MFP has increased my daily calories too which can only be a good thing !!

Good luck to fasters today.

hoops997 · 24/09/2012 08:31

Fast day for me today and I have to go to the dentist cause I broke my tooth! Should be an easy fast day Grin

TellMeLater · 24/09/2012 09:11

Fast day for me!

"Talkinpeace" my primary motivation for fasting is weight control. Most of the immediate health benefits obtained from fasting I would get anyway from low carbing, running 20miles a week and resistance training twice a week.

The science of fasting is so new, so unproven in humans, health benefits are by no means a given....so for me the health benefits are the nice side effect - if they happen....there's no guarantees, so to fast in the hope that you might be improving your health wouldn't motivate me but weight control will.

mistlethrush · 24/09/2012 09:18

OK, so I'm going for it to see whether it might work for me as keeping to a low cal low carb doesn't really do much - so will stick to that for most days and also add in the fast days.

I've had a small bowl of plain porridge for breakfast and I've brought in a DIY hot and sour soup to make for lunch in the office (we have a microwave) - 3 mushrooms, bit of chilli, bit of ginger, bit of lemon grass and some basil leaves and stock powder. I shall report back later on its success or failure!

I shall have a big plate of salad this evening with balsamic vinegar. I'm hoping I'll get all the positives of how I used to feel when I went on a fruit diet for a bit - used to get down to 5 pieces of fruit a day and be full of energy on that and could keep that up for 2 weeks quite happily - but realise that that's not exactly a good routine to get into and haven't done it since I had to to get into my ball dress at uni for the ball at the end of the year Blush

Thelittlestranger · 24/09/2012 09:32

Morning...start of week 4 for me, 1st fast day of the week. Quite happy to do it, after eating all weekend. Although I made some sensible choices this weekend, and have therefore not put on the obligatory 3lbs which I usually have to lose during my fast day today. So feeling extremely positive about losing weight this week, after staying the same last week.

Just enjoying my milky coffee, then won't eat until I have tea with the kids at 5.30. I have a hard boiled egg in the fridge in case I get the munchies. Then off to aerobics this evening, so I'm not sitting in and thing about food.

Considering salmon with roasted veg or chicken caesar salad for tea. The online shop is arriving shortly, so I'll work out calories on MFP.

I too am on this to lose weight first, and other health benefits second. I suspect this is because I'm overweight!! Get rid of the fat, and the other health benefits should follow...

Happy fast day all!

(I can never get my head round kgs...)

ThatBintAgain · 24/09/2012 09:35

Morning everyone. I've roped DH into doing this as well, he did his first fast day yesterday with me. I know what's going to happen though; he'll lose a stone by Friday and I'll probably put his weight on!

Seriously though, have been doing this for 8 days, ADF as well. I had a bit of a blow out on Saturday, but probably haven't been going over 1800-200 on other eating days, and less than 500 on fast days...and I've lost nothing. Maybe half a pound? My clothes don't even feel particularly looser. I'm starting to get really fed up, I swear I could probably not eat for a week and nothing would happen, my body appears to be incredibly stubborn. I'm going to keep on with it, because it's not all about the weight loss, but I'm wondering if should stick to doing Slimming World on eating days, so in theory I can still eat as much as I want but only of certain lower fat things. I know that goes against the spirit a bit, but I don't know what else to do.

littlemissstan · 24/09/2012 09:38

Morning all, first fast of week two for me today! I am a bit worried as we were away for a long weekend with friends in Devon from Thursday to yesterday, so huge meals, pub lunches, lots of pudding and even more booze consumed - which technically should be fine as they were all eating days, but I can't help feeling I will have somehow stretched my stomach to become used to that level of eating and so today will be impossible! Does that actually happen or am I being silly?? We did go surfing, biking and walking so I hope some of the bad is cancelled out...

Thelittlestranger · 24/09/2012 09:44

Littlemisstan, I'm finding each fast day easier despite what I eat on my feed days.

But what I have found happening is that I'm starting to eat less on my eating days, as I just don't want as much....

ChazsGoldAttitude · 24/09/2012 09:58

Fast day yesterday and a run. It went well. 300 cals around 2.30pm and a 200 cal snack at 8pm. Didn't eat breakfast until gone 9am this morning and wasn't ridiculously hungry. English muffin and scrambled eggs.

Gym today. I bet the kids will have polished off the last of the prawn crackers I was resisting yesterday by the time I get home.

RightBuggerforGOLD · 24/09/2012 10:06

Thatbint That sounds like a good idea, can't hurt to try it that way for a few weeks and see if it helps anyway.

End of week 7 weigh in, and I have lost another 3 lbs, so a total of 1st 8lbs. I am also wearing size 10 non maternity jeans!! Although I do have to undo them if I want to sit down. Winning!

Yesterday was an eating day and we went for a mexican, but didnt overdo it the rest of the day, so didnt have that eaters remorse I often feel! Fasting today. :-)

BuntCadger · 24/09/2012 10:06

Looks like an impromptu fast day may be on the cards today as dh is poorly and I'm not feeling so great myself.

Laska42 · 24/09/2012 10:37

eating today and making a curry ...

mumofcrazynamedkids · 24/09/2012 10:40

Thanks Green eggs.

Beginning of 8th week for me, was hoping to do my first 3 day week last week and fast as an extra on Sunday, but I woke up with a sore throat and cold and decided probably best not to. But I also weighed myself on Saturday, and I was 11 2, down from 11 8 starting weight, and after it being quite up and down initially, I am really pleased. I've adjusted my head from focussing on losing quickly, have realised I find it easier and easier as a lifestyle/weight management choice, and as long as overall the weight is going down, then I am happy. But I am so looking forward to getting under the 11 stone mark!

I've been thinking about what many people are noticing which is that we are choosing to eat less, and being more aware of what we eat on non fast days, and I think that is because for many of us we are really having to think about how many calories are in things for the fast days, which is bringing it into our conscious mind, although many of us generally know vaguely the calories of food already, it's quite a subconscious, push to the back of the mind thing, and the 2 days of fasting is highlighting it.

I went to buy a supermarket curry and just automatically checked the calories, when i realised it was 690 I was just like, no way, even though it was a non fast day, I decided to make a salad instead. That is not to say that I am not still eating chocolate on my non fast days, I am, but overall I'm pretty sure i am making better overall choices on the non fast days.

I'm also attempting to snack less and push myself further in between meals as I've realised I enjoy the taste of food more when I feel hungry, I used to think this was a bad way of eating and you should eat little and often, but now not so sure.

fasting tomorrow and thurs, seeing my bf on Fri, can't wait as it will be 12 days apart by then.

mumofcrazynamedkids · 24/09/2012 10:42

rightbugger wow! that is a very impressive weight loss, it seems odd to me that people are experiencing such different weight losses, you and I have been doing it the same length of time, but I have just lost 6lbs, but I guess we're all different. anyway, congrats, really pleased for you!

BelinaTheChicken · 24/09/2012 10:48

Just weighed in to find that I have lost 3lbs in the first week. Really happy with that, only 15lbs to go till I'm at pre pregnancy weight, and I didn't get down to it between pregnancies. I'm in the healthy range for BMI, but I have next to no muscle mass even when I'm fit, so need to be towards the bottom of BMI to have healthy fat levels.

Fast day today, and have two friends coming round for a play date, and I normally feed them lunch, not sure what to do about that, as I won't be eating anything, but will feel rude not feeding them Confused. Maybe I'll offer them soup, then at least I can have some with them and not look like a weirdo

ThatBint I'm not doing Slimming World, but I am calorie counting and trying to make healthy choices on my eating days as I'm a fridge picker, and can add 100s of calories on top of my normal meals without even noticing, so if it's not working eating what you want, it's worth a try!

BelinaTheChicken · 24/09/2012 10:53

RightBugger that is really amazing, and size 10 is brilliant

mumof I'm the same, I'm happy eating chocolate, but if I'm going to eat high calorie foods, I want them to taste high calorie! So chocolate is fine, but high calorie curry not, especially as I'm just as happy with a low cal one, like rogan josh

worldcitizen · 24/09/2012 10:58

Is there a way to prepare a low cal curry??? Would love to know in case anyone has a recipe at hand Smile

mommybunny · 24/09/2012 11:00

Fasting today after a pretty "normal" eating weekend, though one with a cooking course at Le Cordon Bleu on Saturday! It was so much fun, and great to be able to enjoy it without any guilt. Yesterday we had company for Sunday lunch, and when we have company for lunch we rarely have dinner/tea. So I last ate a choccy with coffee at about 4 yesterday. I'm meeting some friends for lunch today and I'm a little nervous as I don't have a "menu" from the restaurant and can't plan in advance what I'll have. I really want to stay on the fast today because I want to see if I do better with 2 feed days between fasts rather than the 1 I was doing last week. But at the same time I don't want to burden my friends with my calorie counting.

Oh, and I finally weighed myself - 10st2 (142 lbs), which is not as low as I'd like but not as high as I'd feared. I'd like to get south of 9st4 (130 lbs), which at 5'3 1/2" is a good "fighting weight" for me at 45 years old. There was a great post earlier up the thread (was if from pookey?) that said in the first 3 weeks you may find you lose nothing at all as your body adjusts to this new WoE. If you can avoid weighing yourself in the first 3 weeks- month you may avoid disappointment and discouragement. So I'm going to lay off till 3 Mondays from now, and see where I get to. I hadn't felt I was seeing any progress, having done 5:2 faithfully for 10 days - jeans were no looser, and my face still as pudgy. But I will use the scales to see progress in 3 weeks' time.

Happy fasting/feasting, everyone!

BelinaTheChicken · 24/09/2012 11:05

lower cal probably a better description! But Rogan Josh is tomato based so lower in calories than coconut milk ones. Waitrose does a Biryani mix that is really nice and they do a low cal version. I'll try and get the recipe for rogan josh from my sister

pookey · 24/09/2012 11:19

How much weight do you need to lose The bint, I was looking on Mark's daily apple and there is a discussion that IF might not be sutable for certain women. There is also a lot on there about women functioning higher when they are fasting which rings true because my grades shot up when I was a teenager and restricted calories (periods also stopped).

For me it's a fast day but I had a metalic taste in my mouth this morning (what's that about does anyone know, somebody else was experiencing that?)so have just eaten half a slice of homemade wm bread and peanut butter will prob have some chopped carrots later and try to eat a small dinner but not going to worry too much about cals. Bit confused about health and likely weightloss of this diet but def want to continue some fasting because it does seem to encourage better eating on non fast days as mumofcrazynamedkids said.

pookey · 24/09/2012 11:27

Hi yes mommybunny was me, I started my period yest so will prob weigh myself tomorrow and then at day 3 ish of next cycle and see what the results are. Bit nervous anout my weight but managed to squeeze into my 14 jeans this morning and don't think i would have been able if I hadn't been following this plan for the last week.
