5K effort won't burn any fat? O_o

@brad_olwin oh wow, that’s so great that you as a professional scientist can help me and the others to understand, thanks a lot! Actually I find it very interesting that we think we “know“ how processes are happening but in reality it’s not finally clear, how they really work on a cellular or molecular level, like you say it is the case when muscle is being reduced due to lacking stimulation. I was thinking the same when the Nobel prizes in medicine we’re given to scientists who found out how the processes of sensing temperature and pressure (?) are working - something as a layman one would consider obvious and simple but on the professional scientific level seems to be very complex.
Concerning ketogenic diets, I made the experience that it seemed to make me loose excess weight fast, but I can not say if the reason is purely because of metabolism changes or if just by not drinking alcohol and eating sweets I just had a a higher calorie deficit than usual.
I found it not very comfortable and changed to a „normal“ diet and now enjoy pasta and the many breads we have in Germany and from time to time a glass of red wine again, though I rarely drink alcoholic beverages anymore since then. Somehow I recognised that I don’t need them on a daily or even week(end)ly basis

@Brad_Olwin speaks the sport science gospel, I’ve been studying this a lot lately. Because of that my food pyramid has 3 sides: protein, complex carbs, and fat!
Back on topic though, the run in this thread is well above aerobic threshold so sugar was burned as I stated earlier, not fat.

You can think of it as economy model of supply/demand. What body sees no use for it does not spend energy maintaining it.
Astronauts pee out calcium from their bones as soon as body “sees” it does not needs it in micro G, it does not matter that their ancestors spent 4.5 billion years evolving under gravity. What did matter in past is that ancestors evolved 4.5 billion years where a cost/benefit situation is a reality and it applies under situations where food was scarce and ones that not utilize cost benefit dont simply survive.

I thought I recognised “Rhabdomylosis”: That’s what Aussie mountain biker Craig Gordon suffered from after the “24 hrs of Adrenaline” World MTB championships in 2006 (as featured in the docu-film “24 Solo”) He pushed himself incredibly hard and was hospitalised with it after the race…actually the article I just checked said it resulted in him being on dialysis for two days.
btw: “24 Solo” is a documentary about 24hr solo mtb racing if anyone hasn’t seen it - very good and worth a watch.

Rhabdomylosis
I remember listening to a few podcasts where elite runners have had it, not good at all and sounds like a very serious condition
I’m just watching a film on Michael McKnight attempting to break the Colorado Trail FKT, he’s a low carb ultrarunner. He even did a 100km race a while back on zero calories just to see if it can be done - think he finished in 17hrs and change which is darn impressive. Pretty sure he also won the Moab 240 last weekend
But diet aside, I think you need to find what works for you as no two athletes/people are going to be the same (unless you’re a twin)

I don’t eat carbs and I do best efforts. So where does my energy come from ?
The perhaps answer to this comes to studying blood glucose and how your body metabolizes fat but also when and how it’s stored.
I love to eat crabs, if you don’t eat crabs, do you eat any fish or lamb?

Yes that’s true - didn’t know the calcium thing
. Amazing that it adopts that fast. -
I got 1g burned fat.

How did you manage to extract 300cal from 50g of carbs?
-
@lexterm77 isn’t 1 g of fat 8 (almost 9) calories?

I don’t know, buy one get one free?

Yes, add up all and you get approximately 4cal per gram of carbs or proteins and almost 9 cal per gram of fat. Anaerobic pathway you get one pay more not the other way around unless “debt” is included into caloric consumption or burner only calculates aerobic consumption?

@lexterm77 yeah I read fat instead of carb, sorry

turns out 5.5cal per gram of carbs, very strange

1g fat
60 g crarbs -
@zhang965 those HR zones seem wrong right? 179 green ?

180 185 is my zone 3
186 196 is z4
Beyond 196 z5I did the test in a lab

so we had:
1(fat)+60(carbs)=297 (my last 5k résultat)
3(fat)+103(carbs)=574 (this 10k)than fat = 50, carbs =4 …

Fat is 8.8cal/g, rest is Lithium Ion

ah ok ,so I got 5.5 cal/g carbs
