Can you please tell me about the healthy amount of calories and grams of fat that should be consumed daily by a teenage female?

Diet for teenager. Depends on many factors: body type, height and weight, amount of exercise or sport activity (how many calories burned each day), the health of the teenager and what illness may be present. Best is to see your doctor for a check up to determine what is the best diet for you as a unique individual.
Depends. Around 1800 to 2500 depending on their activity level, maybe more if very active. Fat consumption between 20 to 30 percent of calories.
