Kay’s compromise is setting her up for troubles. She is doing the acceptable thing by researching the issue however she has missed some finer points. While fats at 9 calories per gram do in fact yield more calories per gram than carbohydrates which are 4 calories per gram and as such do indeed have a greater potential for energy use she is misguided in her thinking and taking an approach where she drops her carbohydrates low and takes in high fat in her diet is perverting the facts.

The event she participates in will be fairly short yet very intense with that in mind as an 800-meter track athlete the Carbohydrates are going to serve her the best. She will require immediate as well as a short sustained use of energy for her event. While she will be using both energy systems Fink states she will mainly be using anaerobic energy system which â€Å"is a major contributor to intense activities that last from 1 to 3 minutes.† (Fink, 2012, p. 50) Undoubtedly Kay must be experiencing some undesired results during her races which she wants to correct.
