Exercise performance begins to decline once water loss exceeds 2% of an individual's body mass.
The remaining glucose is converted to fat and stored into the body as an energy source.
Glucose is a sugar molecule which can be converted into two three-carbon pyruvate molecules through the process of glycolysis and then into acetyl CoA. So, when the body requires immediate energy, acetyl CoA enters the Citric Acid Cycle (Krebs cycle) and ATP is formed. But, when glucose intake exceeds your body's energy needs, acetyl CoA begins the process of fatty acid synthesis (FFA). FFAs become triglycerides that are stored in the fat tissues of the body which can be broken down later to give the energy the body needs.
