The proportion of carbohydrates, protein and fat in three different diets

IELTS Writing Task 1:The table below gives information on the proportion of carbohydrates, protein and fat In Focus three different diets. Write a report for a university lecturer describing the information shown below. Make comparisons where relevant.

The pie charts compare the proportion of carbohydrates, protein and fat in three
different diets, namely an average diet, a healthy diet, and a healthy diet for sport.
It is noticeable that sportspeople require a diet comprising a significantly higher
proportion of carbohydrates than an average diet or a healthy diet. The average
diet contains the lowest percentage of carbohydrates but the highest proportion
of protein.
Carbohydrates make up 60% of the healthy diet for sport. This is 10% higher than
the proportion of carbohydrates in a normal healthy diet, and 20% more than the
proportion in an average diet. On the other hand, people who eat an average diet
consume a greater relative amount of protein (40%) than those who eat a healthy
diet (30%) and sportspeople (25%).
The third compound shown in the charts is fat. Fat constitutes exactly one fifth
of both the average diet and the healthy diet, but the figure drops to only 15%
for the healthy sports diet.

Band 8

The three pie charts illustrate the proportions of carbohydrates, protein, and fat in three diets: an average diet, a healthy diet, and a healthy sport diet.

Overall, people who follow a healthy diet for sport consume the highest percentage of carbohydrates, whereas those on an average diet have the largest proportion of protein. Fat intake is lowest in the healthy sport diet and highest in the other two.

Carbohydrates make up 60% of the healthy sport diet, which is 10% more than the 50% found in a normal healthy diet and 20% higher than in an average diet (40%). By contrast, protein stands at 40% in an average diet, while it accounts for 25% in the healthy sport diet and 30% in the normal healthy diet.

Fat constitutes around 20% of both the average diet and the healthy diet, but drops to 15% in the healthy sport diet. This indicates that while carbohydrates and protein are adjusted significantly for sporting needs, fat intake is reduced.

Band 9

The pie charts compare the relative proportions of carbohydrates, protein, and fat in three distinct dietary patterns: an average diet, a healthy diet, and a specialized healthy diet for sport.

Overall, the healthy sport diet contains the highest proportion of carbohydrates, while the average diet features the largest share of protein. Fat is relatively consistent at around one-fifth for two of the diets but drops noticeably in the sport-focused diet.

Carbohydrates account for 60% of the healthy sport diet, surpassing both the normal healthy diet (50%) and the average diet (40%). Protein, on the other hand, makes up 40% of the average diet, compared to 30% in the healthy diet and just 25% in the sport diet. This indicates that individuals on an average diet consume proportionally more protein than those adhering to the other two diets.

Fat stands at around 20% in both the average diet and the healthy diet, but it declines to 15% in the healthy sport diet. Thus, while carbohydrates and protein ratios vary notably across the three diets, fat levels remain relatively moderate in two but significantly lower in the sport-focused plan.
