I was reading some articles on SP,
Here is the thing I really don't understand,
In this one www.sparkpeople.com/blog/blog.asp?post=is_
It says :
DON'T "Exercise in the fat-burning zone." The fat-burning zone is—shockingly—still a very common workout mode on cardio machines. It is programmed to keep you working at a low heart-rate (intensity) level because at low-energy levels your body uses more fat as fuel. That's is true in theory, but in practice it doesn't work out so well. When it comes to weight loss it does not matter where the calories you burn come from, whether glucose in the bloodstream from a recent meal you ate or stored body fat. What really matters is that you burn as many calories as possible regardless of the source of those calories. And what burns more calories? Working harder.
But in this one, www.sparkpeople.com/resource/fitness_artic
There's a text saying:
Fat-burning tip: Real fat-burning takes place during low-intensity, daily activities—not during exercise itself. The more calories (glycogen) you burn during exercise and recovery, the more your body will rely on fat stores to fuel the rest of your day. So instead of trying to figure out whether (or what) to eat before you exercise, choose whatever will help you put the most effort and time into your workout session. Everyone is different. Don't eat if it upsets your stomach to exercise soon afterward, but if you feel lightheaded or fatigued when exercising
on an empty stomach, then you should eat a pre-workout snack or meal.
So, what would it be? To do or not to do.
Sorry for my English, I'm not a native, I guess we can agree on some tolerance here ;)
