In our last article<\/a> we discussed motivation, and whether it was as helpful as it is made out to be. In my opinion it has its place, but building habits is a better option.\u00a0<\/span><\/p>\n

This week we’re talking about calories burned during a gym session, and why the number looks so small.\u00a0<\/span><\/p>\n

How Many Calories Do I Burn in a Gym Session?<\/b><\/span><\/h2>\n

Question: I read recently that it takes 40 minutes of jogging to burn off a Mars bar, is this true?<\/i><\/b><\/p>\n

Answer: Technically, yes. It would take around 30-40 minutes of jogging to burn the 244 calories found in a Mars bar. But it really is best not to think about it that way. For starters, your metabolism can burn those 244 calories watching TV for around 3 hours.<\/p>\n

That’s right! A 70kg person will burn 221 calories just by sitting down and watching TV. You could sit down for 4 hours, eat a Mars bar, and LOSE weight.<\/p>\n

Secondly, the act of eating the Mars bar itself burns calories, this is called the thermic effect of food. So 15% of those 244 calories will be burned off just by eating the Mars bar and then digesting it. Leaving you with 200 calories to play with.<\/p>\n

As you can see, the calorie debate is a lot more nuanced than people like to pretend. You don’t need to jog to burn the calories from a single Mars bar, the jogging should be performed for other reasons.<\/p>\n\r\n \r\n
