Instructions:
* Determine your daily calorie intake necessary to gain weight using a Calorie intake calculator. An athlete's calorie intake will be much more than most individuals and vary based on your current weight. Establish the necessary weight that you need while considering the position you will be playing in football.
* Identify the foods that will provide the calorie levels necessary to reach your daily goals. It will take a combination of foods to get to the correct calorie level daily. Balance the calorie levels between carbohydrates, fat and protein with 55-60% coming from carbohydrates, 30% or less from fat and 10-15% from protein.
* Build muscle, which weighs more than fat, to keep your body healthy and primed for competition. Choose the right sources for fat, protein and carbohydrates. Eat more vegetables, fruits and dairy while supplementing the body with a good multivitamin. Consuming the right types of calories and training hard will allow your body to gain the right weight.
* Stay hydrated to ensure the body maintains the right balance between fluids and nutrients. This allows the body to process food correctly and generate the necessary energy to complete workouts. Depending on the extent of the workout, sports drinks may provide additional nutrients lost that water can't replenish.
