How many calories of fat do you burn

[MassD07]

i just want to find out, when your on the treadmills and you running 40 minutes , you burn about 600 calories how much of that could be calories of fat.

becuase in venuto's book it suggests that if you run constantly for 20 minutes you should be in fat burning mode.

anymore on that dont hesitate to reply.

lol @ fat burning mode. burning calories is burning calories. people use words like that to make you buy a program, and he is pretty good at making people buy his program.

What? A calorie is a specified amount of energy, the amount of energy it takes to increase 1 mL of water exactly 1° C I believe.

I believe that it depends on how many carbs you have in your system because if you have been running long and hard you might notice you often get a second "wind" they call it when you run out of carbs and then your body starts burning off fat.

Low-intensity activity burns solely fat calories. A walk, because of the nature of its cardiovascular component, burns only fat calories, although it doesn't burn a lot of total calories. Sprints exclusively burn carbs due to the anaerobic (explosive) nature of it, which is why weight training only burns carbs too.

I read that jogs are a little more complicated. A 60-minute jog will burn both carbs and fats. The first 20-30 minutes is spent depleting whatever glycogen is left in your body that was not exhausted overnight. Then your body switches into using fat as the primary source of fuel for the jog. However, there is a 5-10 minute transition period between the carb-burning and fat-burning where the body burns protein for a short period of time while it prepares the fat-burning pathway. 10-20g of protein are burned in this way, which seems to be why pre-cardio protein shake supplementation was justified to prevent catabolism.

As for Tom Venuto's "fat burning mode" that occurs during jogs. Jogs do burn more fats than carbs, but it just doesn't mean that you burn a whole lot of calories this way. Sprints and weight training, due to their longstanding effect on the metabolism for the rest of the day, burn more cumulative calories than low-intensity activity although they don't burn a lot of calories doing the actual session.

Your "second wind" statement might be the carb-to-fat transition I was talking about. Hmm...

Good explanation and it also shows why it is a good idea to do moderate intesnity cardio after weight training.
