Nash,
I too have been told doing c.v i.e running, excercise bike, tredmill etc....
On an empty stomach like you say burns more fat....
But this might sound like a stupid question but when exactly is you stomach empty??
If i eat at 22:00 will my stomach be empty by 01:00??
Anyone know??
The thing is, how fast food is digested really doesn't have much to do with it (when your stomach gets empty)
The vast majority of the digestion process takes place in the intestines, not the stomach. And it really depends on your metabolic rate hence the need to speed up the metabolic rate with something (Speed ,ephedrine... etc)
Metabolism is a process that breaks down carbohydrates, fats and proteins in the food you eat to make the energy your body needs to build and maintain itself. Proper nutrition keeps your body functioning well, but the right foods can also speed up your metabolism. The amount of calories you eat, your genes and the amount of calories that you burn while eating and exercising determine your metabolism.
The body breaks down carbohydrates, then fats and finally proteins. The food that you eat makes up 5 to 10 percent of your metabolic rate.
Now ,after you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion and absorption of water.
Elimination of undigested food residue through the large intestine usually begins after 24 hours. Complete elimination from the body may take several days.
Hence the need for a fasting day during the week as all the Yoga practicing guys are doing...
Here`s someting that might give you an idea of what to eat and how lond does it takes to digest it...
