Answer 1

This diet contains 22 gm of protein

93 gm of fat and 22.022 gm of fat (as we know that 1 gm= 1000mg

hence 22 mg of cholesterol= 0.022 gm)

this will be added in fat part

It is known that 1 gm of carbohydrate provide= 4 calories

1 gm of carbohydrate provide= 4 calories

1 gm of fat provides = 9 calories

Hence Total calories by the above diet = 22x4+93x4+ 22.022 X9

= 88+372+ 198.198

= 658.198 calories

The percentage of calories from the fat part is= (198.198/ 658.198) X 100

=30.11 %
