Answer:
Between 420 and 600 grams.
Step-by-step explanation:
There are no resources which would endorse dietary intake for athletes because of insufficient information. But, there are some sources that recommend carbohydrates intake in grams, depending on how much athlete weighs. It varies from 5 to 7 grams per kg for a regular training and from 7 to 10 grams per kg for the athletes.
7 x 60 = 420g
10 x 60 = 600 g
Jenny is advised to consume somewhere around 420 and 600 grams of carbs each day in order to balance her weight and glycogen.
