Sweating does not directly burn calories and is only a signal that the body's core temperature is increasing. Sweating can create the false impression that the body is burning calories because water weight is shed through the act of perspiring.
Water weight is restored when a person rehydrates her body by drinking water. To burn calories for good, develop a consistent exercise program that incorporates moderate-to-intense physical activity several days each week. Calories can also be shed by maintaining a healthy diet and reducing food portions throughout the day so that the body is forced to burn stored fat for energy.
