How did you manage to extract 300cal from 50g of carbs?

I don’t know, buy one get one free?

@lexterm77 isn’t 1 g of fat 8 (almost 9) calories?

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?

[isazi]

@lexterm77 yeah I read fat instead of carb, sorry

[lexterm77]

@isazi

turns out 5.5cal per gram of carbs, very strange

[zhang965]

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 z5

I did the test in a lab

[zhang965]

so we had:

1(fat)+60(carbs)=297 (my last 5k résultat)
3(fat)+103(carbs)=574 (this 10k)

than fat = 50, carbs =4 …

[lexterm77]

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

@zhang965

Burner appears to exclude anaerobic portion while calorie data does not. I am not sure but someone can confirm.

[isazi]

@lexterm77 now that you say so, I think calories does also include the metabolic calories, so maybe burner only looks at the activity. Could this be the reason?

[lexterm77]

@isazi

On Long walks burner is closer to calorie counter (50cal missing) vs running (progression runs z3-z5 intervals) (130cal missing) discrepancies would increase as time progresses. This is what I thought but data point to something else (hinting at anaerobic)

55min interval 905cal 156g carb 17g fat (770cal in burner)
130cal missing (2.36cal per minute)

90min walk 881cal 119g carb 40g fat (828cal in burner)
50cal missing (0.55 cal per minute)

97min trail run easy 1322cal 233g carb 43g fat (1310cal in burner) this one is accurate

@lexterm77 guys keep in mind the passive calories. They are counted for the workout but should not count for the burner

[lexterm77]

@dimitrios-kanellopoulos

Basal metabolism == passive calories.

[lexterm77]

Found out what it is, sometimes it does not calculate last chunk, hence the missing carbs/fat.

[zhang965]

This time I spent only 33g carbs.lol

@zhang965 I run my 5k in 40 minutes in zone 3 at about 143bpm and my fat burning is off the roof. The zone you are running is in eating in to your carbs rather then fat. From I can see your a serious runner so this is expected at rate you run.
