By definition, the human body generates energy by burning calories. Since Gatorade has calories, it can provide energy. However, if you are not engaging in physical activity or an active lifestyle, those calories instead get converted and stored as fat, potentially leading to excess weight gain.
The nutrition information for Gatorade is based on an 8-oz. serving. An 8-oz. serving of Gatorade contains 50 calories including 14 g sugar. Gatorade sports drink is sold in bottles of varying size. A 32-oz. bottle of Gatorade has four servings, amounting to 200 calories and 56 g of sugar. This amount is equal to 14 tsp. sugar.
Your body needs calories to function on a very basic level. The lungs and heart need energy to expand and contract, and the brain needs calories to process information. You generate energy for these body processes by consuming calories in your diet. Gatorade has sugar which your body uses for energy, and water which is necessary to keep everything working properly.
Gatorade also has water, which your body needs to keep everything working properly. Hydration is just as important to athletic performance as sugar or electrolytes. The best way to stay hydrated is to drink plenty of water. Plain water is easy for your body to process, and inexpensive if you draw it from the tap.
Electrolytes do not provide energy, however they do support important physiological processes important for movement, namely the nervous and cardiac systems. Gatorade contains small amounts of potassium and sodium, the two main electrolytes found in the human body. Both of these are lost in perspiration and can be replenished by drinking an electrolyte-replacement beverage like Gatorade.
Gatorade is sold around the world in many varieties. Gatorade sports drinks are sold in two major series: the G Series, and Gatorade Natural. Each series contains a distinct line of drinks. The G Series includes drinks targeted towards pre-game warm-up, game time, and post-game recovery. Gatorade Natural contains two varieties of drinks marketed for its general "thirst quenching" properties. Gatorade also sells a line of food products under the G Series Pro line.
