Im just wondering how much exercise does a adolescent need to do to burn 12g of fat & how long will it take to work it off?

How do you now its only l2g of fat ? How did you arrive at that figure on a human body?

To lose one pound of fat, you have to burn 3500 calories. So to lose 26.45 of them (that's 12kg), you have to burn 92,575 calories.

Assuming you do an extra hour a day of running or other sport which burns 1000 calories an hour (and that's a hard target, you're going to sweat a lot), it will take about three months.

There are l000 grams in l kg. Youa re talking about l2 kg and she is talking l2 grams. Big difference, so why bother, and l2 grams could be gained right back anyway, overnight, over two days. This looks like a homework question. 1000 grams is 2-l/2 pounds which can be lost walking l/2 hour a day and watching what you eat.

Who would be bothered to try and lose l2 grams ?

Opps, sorry. Didn't notice that. I'm so used to people wanting to lose 12kg overnight.

Oh heck Eileen, I meant to say 'i knew you hadn't noticed that'. Anyway, it worked out to an agree which is the main thing. If you aren't on the metric system then it isn't obvious, in Canada we are Metric, US isn't.

12g is just under half an ounce. In order to burn off half and ounce of fat, you need to burn 109 calories. I'm pretty sure you burn that just by sneezing.
