If I decide to lose weight, how long will it take for results to show?

If you are overweight, your peril is most likely caused by dehydration and poor distribution of liquids in the tissues. That portion of excess weight usually quickly goes away during the first 2-3 weeks. In some cases,  the weight may decrease by 20-30 pounds (in people with a lot of excess weight). After 1.5 - 2 months, your weight will start decreasing slowly or intermittently.
