Final answer:
Based on the recommended fat intake for a 2000 kcal diet, which is 65 grams, Mr. J. should consume no more than 81.25 grams of fat for a 2500 kcal meal, following the proportional increase in calorie intake.
Step-by-step explanation:
To calculate the maximum number of grams of fat that Mr. J. should consume when eating a meal of 2500 kcal, we can refer to the daily recommended intake based on a 2000 kcal diet, which is 65 grams of fat. First, we ascertain how much fat is recommended per calorie by dividing 65 grams of fat by 2000 kcal, thus obtaining a ratio. We can then apply this ratio to the 2500 kcal meal to find the recommended amount of fat.
The calculation is as follows:
(65 g fat / 2000 kcal) × 2500 kcal = 81.25 g of fat
This result means that based on a proportional increase from a 2000 kcal to a 2500 kcal diet, Mr. J. should consume no more than 81.25 grams of fat in his meal to adhere to recommended dietary guidelines.
