Just wondering if anyone has tried this and how it went? I am about ten days in and coping well so far.

I have been low carbing for years on and off, and on 5:2 since Sept which seems to make the fasting easier.

I've decided to de,-lurk and officially join this thread. I found it by chance a week ago and thought I'd give it a try. I don't have diabetes or pre diabetes that I know of, but my body fat levels put me at risk.
I'm another one that used to be on the old 5:2 threads. That worked well for me for a while but then I started over compensating on NFDs, my stomach started feeling weird and I would get really cranky on fast days. As I wasn't getting results I stopped, and put the weight back on.

Anyway, I'm tweaking the BSD 800 a bit by eating more at weekends but staying within my TDEE and staying more or less in the food types rules.
A week on and I'm a couple of kgs down which is great, the first week I was fairly hungry so managed more like 900-1000 and had wine some days. Yesterday I hit the 800 no problem and won't have any wine til friday.

Obs2016 · 23/02/2016 08:20

Welcome Sputnik. I do think that first week is a big thing and adapting is huge, so that first week is major and then spurns you on to being closer to the 800 in week 2.
I cut down and down in week 1-2/3and then found bring strict so much easier, in week 2/3 onwards.

mootime · 23/02/2016 08:42

Mornjng all, week 2 day 2, going to be on 800 again today (am doing 5:2 BSD) I've woken up feeling HANGRY. I've had a coffee with actual milk but that hasn't worked. I know if I have a small breakfast I won't cope for the rest of the day so I may have to just ride through it...

buzzybuzzybeeshoes · 23/02/2016 09:51

Hi, am also delurking after finding this thread by chance last week Smile

I'm veggie and I know I eat too many carbs and not enough protein. I always had a slim waist (carry weight on my boobs and hips) but I've noticed a belly that wasn't there before, plus I don't know whether it's my imagination but I have tingly feet. I must be at risk of T2 at my age (39) and weight (14 12 - am usually 14 8 or 14 9 but half term hit hard!)

I exercise a fair bit - 2 or 3 hours of swimming (constant lengths and drills under pressure to go fast/keep up), 1-2 hours of running (slow pace at my weight - 12 to 13min miles Blush ) and around 12-22,000 steps on the Fitbit per day. Will I die of hunger?

buzzybuzzybeeshoes · 23/02/2016 09:53

Aah, sorry! I don't do all that swimming and running per day, that's per week. I'd be in bloody amazing health if I did that per day!

Elvish · 23/02/2016 15:26

Hi, I thought I'd join the lurkers in delurking!

I'm on Day 2 of the 800 BSD. Weighed myself yesterday at 13 5 and managed to stick at 850 cals for the day which I was very pleased with.

On track again today I think, yogurt and blueberries for breakfast, home made hummus and veg for lunch. Was really craving something sweet this afternoon but I had a black coffee and that has put it off for me.

I'm tracking using MFP, but I can't believe the variance in the suggested cals etc. For example I'm going to have prawn stir fry tonight and for 100g of raw king prawns the cals go from 66 to 143?! Confused

Any suggestions for the most accurate way to use MFP - should I just enter everything myself from the packet?

Not2bObvious · 23/02/2016 17:49

Nice to see more folk here, great to have more people to chat & share with. Great low carb day here but calories are over the 1000 (1042 actually) but I think I'm ok with that. I started the plan with the intention of 5:2'ing it in a reverse fashion of 5 days 800-900 and 2 days 1200-1600 but the first week didn't quite follow that. I'm allowing myself 1200 today, will aim for no more than 900 tomorrow. Moo I remember hangry on 5:2, it broke me eventually. Haven't felt it yet on this, although it's only day 6 for me

yumyumpoppycat · 23/02/2016 19:11

Elvish if you have MFP on your phone you might be able to scan the barcode to get the info. I tend to check the packet when I am being thorough and see if it matches up as often I eat the same food again and again so from then on I just select the item from the frequently or recently used tab.

Buzzy hopefully Bigchoc will come along as she know a lot about fasting and exercise.

I am reluctant to enter all my cals today as I can tell my period is going to arrive this eve and the carb monster is raging so I have pretty much given myself the day off!In honesty it should be well under 1400 though.

Uphillanddowndale12 · 23/02/2016 19:16

Can I join in? I've just ordered the book. I'm also an off the wagon 5:2er. I just can't seem to get on with the FD/NFD routine: I was getting headaches and cravings. I don't think I'm heading for t2 diabetes but I have a problem with sugar and find it can affect my sleep and makes me a bit jittery. I had a glucose test a few years ago that was 6/7 which scared me.

I'm an aged m'netter and I want to delay the affects of aging as much as I can - especially as my mum and an aunt both have Alzheimer's

I've looked up the blood diet website and it makes a lot of sense and I love beans and Mediterranean type foods

Ive done Ww and was toying with rejoining but I know it won't work for me in the long run

So.... Here goes ...😀🍷🍉🍒🍟🌮

Sputnik · 23/02/2016 19:16

Yay, more de-lurkers! Any more out there?

Buzzy I think you might get pretty hungry on that exercise plan, and possibly end up losing muscle? I asked about exercise over on the fasting and exercise thread and was advised to do less swimming and more resistance training.

I was worried also about getting enough protein from 800 cals to avoid muscle loss, as a veggie that's even harder as I find that many veggie sources of protein carry with them either fats ie cheese and nuts, or carbs with pulses etc, and that pushes up overall calories. I don't eat meat either, but do eat fish and have had a lot of tuna and salmon in the last week!

Sputnik · 23/02/2016 19:25

That's how I was on 5:2 too Uphill, my body just didn't like the irregular routine. And I decided I didn't want to spend 2 days a week snapping my family member's heads off!
So far this seems to agree with me much better, the extra 300 cals make all the difference and I am still getting some fasting benefits as I usually don't eat til lunchtime.

BigChocFrenzy · 23/02/2016 19:42

Buzzy To retain muscle on 800 cals daily (or on most days) I recommend (based on the book, plus other IF research):

  • cutting right back on prolonged medium intensity cardio like swimming or running. Instead, build up to your 10,000 daily steps
  • do resistance training 3-5 days per week
  • and Dr M's HIT Fat Blasts - which are literally a few minutes @ 100% effort on 3-5 days per week.
OttiliaVonBCup · 23/02/2016 19:47

I can't get organised, but I will persevere.
I'm sticking mostly to the plan, but might be over with the calories.
Must download MFP.

I do at least 12 000 steps a day, some days more, will try and squeeze in a fitness DVD tomorrow.

BigChocFrenzy · 23/02/2016 19:48

Dr M wrote on his site that those who have problems with classic 5:2 FDs may well have blood sugar issues.
He says the BSD is better suited to them, including the 5:2 BSD version with 800-cal FDs.

Those with T2 / preT2 / insulin resistance probably need to do maintenance BSD permanently (daily BSD around TDEE, plus small sides of starches), or they'll return to where they started

BigChocFrenzy · 23/02/2016 19:51

Fish and eggs are super healthy proteins, quite low cal and great for muscles.
No need for meat or poultry if you don't want them

OttiliaVonBCup · 23/02/2016 19:59

I buy egg white in a box, Two Chicks, for egg white omelettes.

ErnesttheBavarian · 23/02/2016 20:00

Hi, so I started yesterday. I haven't managed to make it to 800 cals, do you think that's ok? I don't eat breakfast and so had the Avacado tuna for lunch. Then I had fish soup for dinner and was stuffed.

I am weirdly thirsty and have drunk well over 3 L and still feel thirsty. But despite drinking so much am constipated Sad and have had headache on and off all day.

If I don't eat breakfast I dot think I'll make it to 800. But to be honest I am a bit of an all or nothing person. I find it easier to eat v little than to eat just a little bit if that makes sense. Is having so few calories a problem? Saying that, the scales don't show an amazing drop or anythingHmm I really think my thyroid disease is a very tenuous bugger.

Laska5772 · 23/02/2016 20:26

just checking in .. well my weekend saw me gain a couple of pounds!Sad so definately need to not have any more wine until the 8 weeks is over , but our next 'thing' is a wedding on 18th march .. and that coinicidentally that will be the 8 weeks, .

Today i have not really been good, but it has been all been low carb howver have eaten almost 1000, cals ..

Yesterday I was under though..

Tomorrow I must get my sh*t back into action !!
I have spent this evening looking at beach wear though. thats inspiring..

lrb978 · 23/02/2016 21:12

Hello to all the de-lurkers :)

Day 7, ended on 750 cals today, and that included 10g of 85% dark chocolate Grin. I have managed 2l each day since (including) Sunday. Felt hungry today, but it is the first time I have really felt hungry, and I am coming up to that time of the month I think, and I often get the munchies in the run up. Ignored it though, drank my way through it, and carried on regardless Smile.

Might try and weigh myself again tomorrow, but will be on a different set of scales so may not be an accurate reflection of weight lost since Sunday. However my trousers were definitely looser when I put them on this morning so something is happening.

I do need to try and work on my exercise now, as I am doing nothing on top of my general day to day living. Work can be anything from sitting down most of the day to being on my feet and lifting folders of varying weights all day, normally somewhere in the middle. But I really need to start adding in some extra walking at the very least. However I am really pleased with week one, roll on week two Grin.

Obs2016 · 23/02/2016 21:21

Really Laska. I can't bear yo even think about me in a bikini right now Wink

Laska5772 · 23/02/2016 21:29

Positive thinking OBs and working together on this.. thats the stuff,

It doesnt have to be like that ..

buzzybuzzybeeshoes · 23/02/2016 22:11

Thanks bigchoc for the advice. I'm going to struggle with giving up swimming, I think, but don't want to lose muscle so perhaps will have to think about doing so. Resistance training sounds like a good idea. Would yoga/Pilates count or would that be resistance with a band? One of the swimming sessions is interval training. I do my 10,000 daily steps (usually around 15,000, generally manage over 20,000 a couple of days a week) anyway so no worries there.

Sputnik thanks for the link to the fasting and exercise thread; looks amazing and full of good advice so am going to have a good read through that.

Just about to plan some meals for my first 800 cal day tomorrow. Alas I don't eat fish either and eggs are one of the two foods that I genuinely can't force down (bananas being the other)! I've got a freezerful of Quorn and a cupboard full of beans though.

BigChocFrenzy · 23/02/2016 22:13

Ernest For headaches, have a teasp Marmite or a tbsp unsweetened soy sauce, both neat, to replenish lost salt & minerals.

The odd day below 800 cals doesn't matter, but you really should try to average 800, both to obtain sufficient nutrients over the 8 weeks and to avoid your cortisol levels getting too high with stress.

You could either eat breakfast - even a handful (about 30g) nuts - or increase the size of your lunch and supper.

Some people who are v slow losers may take a few days to show scales losses, because weight naturally fluctuates day to day, depending on amount of undigested food, retained water, hormonal swings etc.
So, these blips can hide a small loss.
Just be patient and on 800 cals low carb you are bound to see weekly losses

buzzybuzzybeeshoes · 23/02/2016 22:14

lrb ignoring the pmt munchies! You've got a will of iron. I suppose by definition it's going to have to happen twice in the 8 weeks - hadn't thought about that!

BigChocFrenzy · 23/02/2016 22:34

Buzzy I'm concerned about the effects of prolonged cardio training on a VLCD, in case you lose muscle.
So I suggest keeping the interval swimming and consider replacing at least some of the other sessions by strength / resistance training - replace don't add, or you would be overtraining.
You have plenty of cardio with walking.

btw, when you change your program like this for a couple of months, then return to your normal routine, you might well notice your swimming performance has improved

Pilates / yoga, if it really works the core muscles, is fine as one of your weekly sessions.
To retain muscles, I recommend additionally 2-4 days working the main muscle groups - shoulders / chest and thighs / bum, either with
reasonably heavy barbells: deadlift, squats, bench press, shoukder press, bentover row etc
or bodyweight exercises: full pressups, tricep dips on a step, deep squats & lunges, plank.
