Final answer:
An individual on a 2000 calorie diet should consume between 50 to 175 grams of protein a day, based on the AMDR for protein which is 10-35% of daily calories.
Step-by-step explanation:
According to dietary guidelines, the amount of protein often recommended for an individual on a 2000 calorie diet ranges around 50 to 175 grams per day. This recommendation is based on the Acceptable Macronutrient Distribution Range (AMDR) for protein, which is 10-35% of daily calories. Therefore, using an average value of 4 calories per gram of protein, one following a 2000 calorie diet could consume anywhere from 50 grams (10% of 2000 calories) to 175 grams (35% of 2000 calories) of protein each day. It's important to consider factors such as individual body composition, age, and activity level which can influence protein needs.
