Question:
Which will burn more fat, walking or jogging?

Answer:
Walking a mile burns about the same number of calories as a mile of jogging.  The important thing is to try to exercise at a level of moderate-intensity.  This is equal to exercising at 60-85% of your maximum heart rate.  To determine your maximum heart rate, subtract your age from 220. Multiply that number by 0.6 or .85 in order to obtain the rate at 60-85%.

Question:
How long do I need work out before my body starts burning fat?

Answer:
An aerobic workout (like walking) for 30 to 45 minutes three times a week is enough to burn fat.
