5K effort won't burn any fat? O_o

I did a 100km ride after 18h fast and took only water with me (so in the end 21h+ fast). Almost only Z1. I expected different result:

@lexterm77 once my toe is back to business, I can share with you guys how fasted long runs or intervals look like. 24-48h fasted and blood glucose levels if you are interested.

(Might have a few data from prev days as well)

Totally interested. Started on fasting and also “ordered” first month of supersapiens to test.
More focus on loosing weight and stabilizing appetites etc, but everything that comes with it is bonus.

@andré-faria

Fasted 28h and 2+ hours workout. (does not include 30 min warmup. )

Here is the workout

Watch that witb fasted workout + not z5 the intervals (except the last that I pushed more) kept the lows of HR low (no increase as usually happens).

Blood glucose was low, expected but it didn’t have any impact.

Will test more when I am better.

Likarnik

@andré-faria yes, I calculated zones based on my LTHR (tested both on run and bike, I averaged 182bpm/20min).

@Dimitrios-Kanellopoulos great effort on 28h fast!

@dimitrios-kanellopoulos

This morning I was able to go 32g/h fat average that is only at 210W at 63% of VOMax. Fasted 12h and hung over.

@dimitrios-kanellopoulos Nice job, but what’s with the fasting about? If I may ask and I’m not indiscreet.

isazi

I think this [1] is not computed as HR zones, but as % of VO2max, therefore some people may see strange results if compared to the zones they have configured.

I eat pasta at least once a day, sometimes twice

[1] with this I mean the S+ app

What good is pasta if you don’t grow/cook your own tomato sauce?

isazi

@lexterm77 never had to buy tomato sauce when I lived in Italy, my family buys few hundred kilos of tomatoes in the summer and makes sauce for the rest of the year in bottles

@isazi

I understand completely, I bought “tomato sauce” in a super market and I was so disappointed I started my own garden like my family did in Europe. I got maybe 5kg per plant 25plants this year, ate half of them raw if not more.

Nothing beats pasta & tomato sauce

This may be the last box this year.

@andrasveres nothing is up. It’s a habit. I just eat once. Only water in-between and training.

Not to polute this topic, if you feel like we can open a new topic, but can you elaborate on why your started and how you arrive to that schedule, seen as benefits?
Been reading a bit on reddit, mostly for weight loose, and even started slowly with the 13h fast, but very curious about arriving to one meal only and having lot of energy

I was wondering on the same thing… maybe the body got efficient on storing and using fuel over time.

@andrasveres I think evolution has formed us humans that way, that we can run on different ‘fuels’ depending on what was around in our habitat. The Inuit had only less carbohydrate rich food up there in the Arctic cold (besides same algae’s) , but lots of fatty cold water fish, while in an warmer and water rich environment there were plenty of carbs you did not to have hunt down but could just pick up. So I think al lot depends on you genetic “heritage” how you react on different energy types. But those humans who made it through the thousands of years are pretty sure the ones who could “fast/starve” for a while without loosing their ability to hunt or go out and gather food. The others are most likely not our ancestors . So I guess fasting and activity should (to a certain point where one has fasted too long) not be a problem and I could imagine that somehow it makes you more “committed” or gives you some “enhanced” feeling !?

You could be right on this one as I perform much better in the morning on empty stomach, than on evening, when I already had some meal over the day.

DMytro

@andrasveres or it might be because you are getting tired over the day?

@dmytro might be that too. If you ask me, I think it’s a complex equation. (for which I can’t give respectful result without transforming myself into a lab rat)

ChrisA

@andrasveres same here - I run best after some water or coffee in the morning without eating anything or only small amounts . But it’s for sure a very complex topic and I think it’s very individual
