Training and diet talk…

…then eat it with a load of butter?

Quick note about “dietary calories” (chemical kilocalories) – they are defined as the amount of energy it takes to raise the temperature of 1 kilogram of water 1 degree C at sea level when oxidised (burned) to completion in an atmosphere of pure oxygen.

Whilst a useful measure of potential energy content this is obviously not how the body obtains energy from food. This is dependent upon a variety of factors such as aerobic Vs anaerobic metabolism, rate at which molecules can be transported both around the body and across membranes, availability of metabolic co-factors (vitamins/minerals etc) and enzyme levels (to name a few of the obvious ones).

So if your body looks like this:

then count calories to your heart’s content, otherwise be slightly more circumspect about eating by numbers.

is that Molly’s insides ?

…then eat it with a load of butter?

No. The butter goes in your Mocha-Frappa-La-De-Da-Acino. Possibly with a cheesecake topping.

I’ll have it with fries… supersized.

Your fries come with inside your bucket o’ coke.

Right. 100g of cooked red kidney beans 17.5g carbs. There are 400g in a tin, so that’s 70g for a whole tin, which is a decent amount to eat if your meal is based on beans, speaking from experience.

There are 20g of carbs in a slice of Hovis Best of Both thick sliced. So four slices of that (as you might have in a sandwich based lunch) is similar amount of carbs to a whole tin of beans.

However pinto bean were only 10g carbs per 100g, so a whole tin of those is only going to be as much as two slices of bread. If you have say toast for breakfast, sandwiches for lunch and maybe a snack at some point in the day you could easily be on 6-8 slices a day, that’d be up to 160g of carbs. If you were filling up on beans you could get that from a little over two cans of beans. Which if you are eating really beany meals isn’t as hard as it sounds. I’ve made chilli with six or eight cans in it and eat maybe an eighth of the finished product. Also if I rustle up a quick dhal for a curry I can easily eat most of a can no bother.

We talking total carbz or net carbz (minus fibre)?

No iDea… where do we stand on custard? I have powder, I have milk??

WARNING WARNING WARNING!

REALLY BAD JOKE ALERT!

No iDea… where do we stand on custard?

Anywhere you like, be a bit messy though.

THANK YOU AND GOOD NIGHT!

where do we stand on custard? I have powder, I have milk??

I think that if you don’t mix them nor ingest them (separately or mixed) you should be fine.

‘pends how thick, surely?

Molly, 1 can equals 70g carbs. That’s no different to 100g of pasta or rice, a decent size meal. So why do you still feel hungry after eating beans? the carb content is the same.

Kev

‘pends how thick, surely?

I guess you could add cornflour, if we are getting scientific.

the carb content is the same.

Net carbz is lower, due to a higher fibre content in the beanz.

Starch carbs aren’t the same as bean carbs and carbs in the food don’t necessarily equate to carbs absorbed by the body.

You could weigh out a certain mass of coal, wood, oil, paraffin, petrol and avgas that would contain the same numerical value of calories but they certainly wouldn’t burn in the same way – same with food carbs.

The numbers on the packets and in the nutritional tables are only approximately relevant to how useful that food may be to your body for energy production – that to me is why iDiet is so useful as a basis for healthy and productive eating, it doesn’t rely on numbers but on real life experience.

Find what works for you, tinker with it and learn from your bodies response – it’s the only way really 😀

What about making porridge with custard?

Well.. that is an interesting question. As I understand it, there are loads of factors that lead to feeling full. Blood sugar, the amount of stuff actually in your stomach, there’s some hormone or other secreted by your stomach lining in response to carbs, and there’s the brain aspect too. That’s not to say it’s in your mind as such, but I think your brain has a lot to do with how hungry you feel. I found that if I eat very plan dull foods I feel full pretty quickly, whereas if something’s yummy I eat a lot more.

I think if I eat a load of beans my blood sugar doesn’t go up quickly, and my brain and my stomach lining have not tasted carbs cos it’s still locked away in the fibre. Incidentally, if I do eat a huge serving of beans and feel hungry, I can eat just one biscuit or even a few raisins, and I feel full immediately.

Microwave is going…

Microwave? You always struck me as the sort of person who cooks porridge on the hob.

/Yeah I went there.

molly, I reckon it’s the brains reaction to the sugar levels, or lack of in the of case beans. As we are all sugar addicts our brains are waiting for the sugar hit before it tells us we’re full. Then, because of the nature of sugar we want more despite recognising we’re full. Therein lies the problem, I think. I just try not to rise to the sugar craving, if I do I’ll eat a couple of satsumas or something, that works for me.

of to Zzzzss now. Yoga tomorrow.

Kev

I tend to agree, Kev. A lot of this is psychological, a little like I imagine kicking fags to be.

Sometimes if I just think of cakes I am suddenly hungry whereas I wasn’t before.. oh wait.. this is a well known effect 🙂

So today’s topic is training, lactate threshold training to be precise.

Is there a cheap / easy way to determine what one’s threshold is?

I’d also like to know how people have got on with determining their max HR’s.

Diet is off topic today… unless it can quickly help to improve one of the above.

Run 3-4 times 800m flat out, measure your highest reading. Or same thing up hill. You have to be honest with yourself and ask if I was being chased by a Tiger could I go faster! (Sure you could but you know what I mean)

Any x-your age etc is rubbish imo, I have seen some widely differing measurements.

Agree on the age thing, unless I’m still less than 21.

Do max HR’s differ between sports? Matt Fiztgerald reckons they do.. but IMO max is Max?

Uphill sprint at the end of a bike race.

You think you’re going as hard as you can when the sprint starts, then you try to sprint as hard as you can to the line. Death with extra death on top.

Having said that, maybe you can’t reach your max HR after 2+ hours of racing anyway. so perhaps the 3x800m is the best option

They differ between sports as different movements use less or more muscle mass – swimming max HR is lower much than running max HR.

Re’ lactate threshold, it varies day to day – as you saw yesterday :-/

Your threshold is just that, go on feel. What intensity can you sustain on a given session…

I understand that, but if someone is calculating HR zones for running and cycling say, should they calc them differently.

There seems to be so much written about zone training which I’ve always eschewed in favour of ‘feel’.

stick with ‘feel’

HR is slow to respond and affected by lots of variables

I’m looking forward to doing a nice long ride that ‘feels’ easy. Think I’m going to cruise the next sportive.

Not sure how relevant this is.

But I finally managed to get out on the road bike yesterday.
I cycled north west out of Coventry.
Very windy, very hilly.
I ran for 2.5 hrs on empty / stored reserves.
Ran out of water in number one bottle and then hit the 50/50 water and juice I had in number 2 bottle.
I’d never usd the 50/50 mix before.

I certainly slowed after 2.5 hrs.
The 50/50 may have helped as after 2.5 hrs, I could keep going, but could only manage short bursts of go.
Does this describe me hitting my lactic threshold ?.

Sounds like you ran out of stored fuel and were knackered.

Well, while asking on here, I’ve had a quick google for lactic threshold.

Seems, based on my ride yesterday, that yes, I may have depleted most of the glycogen in the muscles I was using.
But it also seems that as a function of using that stored energy, that there must have been lactic acid present I the muscle ?.

Also, when I reached this point, a feeling I became aware of.
That I couldn’t go as hard, anymore, but for short bursts.
Then the 50/50 may have assisted ?.

They differ between sports as different movements use less or more muscle mass – swimming max HR is lower much than running max HR.

I’ve notice my max sustainable HR whilst running over 10k has dropped by about 10 beats over the last couple of years (though the speed hasn’t). Is this just because the muscles have become a bit more efficient and aren’t stressing the cardio-vascular system so much, or have I just become lazy and I should still be running at that same HR?

lactate is used as fuel by muscle, most notably heart muscle. it’s not the bad guy

Ian.

I would have thought that as a function of the natrual aging process.
That we are all destined to have lower maximals as we get older.
Until it becomes… Zero 😯

So, after my 2.5 hrs and becoming distinctly aware of not being as strong on the bike as I may have been an hour earlier.
(started to lose my climb)
Is this related to the build up / presence of L/A ?.

Yes, I have caught that the acid can be used, even though its a by-product of the primary fueling cycle ????

The trouble with riding on feel, is that I end up going 85% all the time, and my form plateau’s, recovery rides are as important as the hard rides….I’m beginning to think that 75% of my riding should be below 75% effort…

So how do you calculate 75%?

How did you calc your max?

I hope not at 5 beats a year! 🙂
/does maths.
It’ll reach zero at 82 😯
