Does eating healthy help me in the admissions and testing process?
The short answer to this question is yes. In the doldrums of Junior year when you are burdened with SAT test prep, college visits, and a mountain of school-work keeping yourself healthy is essential.
Plan your meals regularly. Be sure to get a good breakfast. Many people find they have little appetite in the morning but its vital to get something in your system. You will find yourself more awake for first period classes and SAT work. It also serves to get your metabolism moving. Be sure that your meals also are filled with fruits, vegetables, and lean protein. This nutrient and energy rich diet will keep you healthy and energized.
A regular exercise routine is also vital in this time. Countless studies have shown the positive effect of vigorous physical exercise on mental acuity and SAT Testing. The short of it is, your mind is sharp when your body is active. You are more engaged and your creative and analytic centers get aided by the rush of endorphins triggered when you exercise.
Exercise and diet both are forms of self-discipline, which is key in this time of your life. Only by keeping regular habits, and holding yourself accountable can you achieve all that you deserve in your junior year. Practicing these habits is a significant piece in the larger puzzle of staying on task and pushing ahead. Your focus will be richly rewarded at the other end, when you are accepted to college and able to enjoy the fruits of you labor at the end of senior year.

A healthy diet is good for your body and your brain. Studying and taking the SAT takes a lot of energy and it that energy comes from what you eat.
