Weightloss Challenge v 1.1

[GTRacing]

I can burn up to a 1000 kcal/hour during training. this is the number my polar gives me. I'm assuming this is kilo cal/ 1000 1000 cal? sounds allot. what would be the ave cal needed per day? how would you get that number? are you guys on cal or kilojulles?

Calories which is the same as kcal. On most foods you will find kj, divide by 4.19 to get Calories

HOW THE FRIKKADEL, do you folk fit in normal family life and cycle and work!

 

Its just maddness I tell you.

Google - daily calorie calculator. I may be wrong but I choose sedentary as my excersise level and add Calories on the days I train from my HRM. The other choices there like excersise 3 times a week average out the extra calories over the rest of the days but their idea of excersise 3 times a week and what you actually do on those 3 days can be way different.

What is that?

Slow down.... Cal and kilo cal. same but they went to different schools together. with a cuz KJ 4.19 removed.

If I burn 1000 k cal, that equates to two meals? (small meals)

[chris_w_65]

Problem is different Calorie calculators give you different answers to the same question. For maintaining my current weight the one tells me 2000 Calories and the other tells me 2400 Calories. That is the difference between eating a big fat avocado and not eating one

The 400 Calorie variance between the 2 calculators is actually the difference between losing a pound a week and losing a pound a month

Is just convention, people talk about calories but 99.99% of numbers states are in kCal.

 

EDIT: When refering to calories, can also obviously be stated in KJ

I took out a 3 year plan yesterday to get in shape. Now they just need to complete the gym in Lynnwood, then I can start training again... Seeing that I was told to stay off the bike for a few months...

didn't read the whole thread, but here are some calorie basics:

 

Calorific value of common food types

 

1) Calories (in normal spoken language) actually refer to Kilo Calories (kCal), so that's the unit here. A kCal is NOT a kJ (kCal = 4.18 x kJ)

2) Average red meat portion: 3 kCal per gram

3) Average White meat portion: 2kCal per gram

4) Pastries, crossaints & chocolates: Between 3 and 5 kCal per gram

5) Fat / Oil: 9 kCal per gram

6) Dry starch (rice / pasta): can't remember to the pin, but think it's about 2 kCal / gram

 

The hard science about "fat" weight loss

 

Every kg of fat contains 9000 kCal. Most of us (reasonably active males) burn 2500 - 3500 kCal per day.

 

So even if your body would only use fat as fuel source and you don't eat anything (which is never the case), it would take 3 + days to burn a kg of fat. If you lose weight faster, it's water, muscle or something else.

 

Its very hard to maintain much more than a 500 kCal deficit (eat 500 kCal less than you burn) on a daily basis, so it's typically about 2 weeks of work to lose a kg of fat...

 

Not saying this to discourage anybody, just to keep realistic targets in mind!!!

 

Good luck with the challenge

Almost correct. If you eat a gram of fat then it is 9 Calories. If you are burning your own fat then there are only 7.7 Calories per gram, there is some water stored in the fat

you meant that a given volume unit of body fat contains only 85% (7.7 / 9 = 85%) actual fat. That means that you will lose 1 kg of weight (by burning 7700 kCal), but 15% is water, so you still didn't lose a kg of fat...

 

Fact is that a kg of fat is a kg of fat, and it allways has 9000 kCal per kg. Whether you consume it, or whether you burn it, so no, you have to burn 9000 kCal to lose 1 kg of fat
