This is where Formula #2 comes into play: Water Oxygen = Fat burning
Basically, the body needs water and increased oxygen to burn fat as an energy source. The water intake should be anywhere from 1/2 gallon for women and up to 1 gallon a day for men. See the “Water Plus Oxygen Equals Weight Loss” article if you are concerned about drinking “too much water.”
As you add more water to your system, your body will be able to use the retained water for excretion, prompting almost immediate weight loss that is healthy. This is not the same as sitting in a sauna and sweating which actually DEHYDRATES you. Adding water will REHYDRATE you and enable the body to burn more fat (as long as you increase your oxygen intake by doing some form of exercise). Walking, swimming, biking, jogging, calisthenics, and even yard work can help with working your cardiovascular system.
Here are some sample calorie expenditures for a variety of activities for people who weigh 130 – 190 lbs. If you weigh more that 190 lbs you will actually burn slightly more calories than a lighter person.
