The pie chart presents the percentage contribution of different macronutrients to a typical 2,000 kcal diet of a person. The typical energy density of these macronutrients is given in the table. Macronutrient | Energy density (kcal/g) Carbohydrates | 4 Proteins | 4 Unsaturated fat | 9 Saturated fat | 9 [Pie chart — Carbohydrates: 60%, Proteins: 15%, Unsaturated fat: 15%, Saturated fat: 10%] The total amount of fat (saturated + unsaturated), in grams, this person consumes is: A. 44.4 B. 77.8 C. 100 D. 3,600

Answer: 100 grams of fat (saturated + unsaturated combined)

1. Determine total fat contribution from the pie chart: From the pie chart, the total fat (saturated + unsaturated) accounts for 45% of the 2,000 kcal diet (the image shows Unsaturated fat = 35%, Saturated fat = 10%, giving 45% total). Fat kcal = 0.45 x 2000 = 900 kcal.
2. Convert fat kilocalories to grams: Both saturated and unsaturated fats have energy density 9 kcal/g. Total fat grams = 900 kcal / 9 kcal/g = 100 g.
