Essentials of Nutrition for Sports

(Nandana) #1

Each gram of fat supplies 9 calories. Therefore, multiply total daily calories by 30% and divide by 9
to determine your maximum daily fat allowance in grams.


For example, suppose your total daily intake is 2,100 calories.
Multiply by 30% to get 630 calories

from fat. Divide by 9 to get 70

grams of fat, your maximum daily fat allowance.

For a diet targeting 20% of calories from fat, multiply total daily
calories by 20% and divide by 9 to get your daily fat allowance in grams.

For example, suppose your total daily intake is 2,100 calories.
Multiply by 20% to get 420 calories

from fat. Divide by 9 to get 47

grams of fat, your daily fat allowance.

For a quick reference to fat allowances for other daily caloric
intakes, see

Table 16. Caloric and grams fat allowance based on daily calories.

Controlling Weight

Total energy intake is the key factor in regards to weight control
regardless of the proportion of protein, fat and carbohydrate in the diet.

Fat is calorically dense. Fats make foods calorically dense. A 4-
ounce portion of oil has about 1,000 calories, but 4 ounces of carrots, celery, apples, or lettuce have less than 50 calories.

Higher-fat diets are moderately hypercaloric when compared
with diets containing less fat. At isocaloric intakes, low-fat diets do not produce weight loss.

Saturated Fatty Acids,

Trans

Fatty Acids, Cholesterol

Intakes of saturated fatty acids,

trans

fatty acids and cholesterol

have each been independently and positively associated with lipid biomarkers of heart disease including LDL-cholesterol.

Excess intake of these types of fat

increases the risk of coronary

heart disease.

It is neither possible nor desirable to achieve zero percent of
energy from saturated fatty acids or

trans

fatty acids. Some intake of

these fats is necessary to have an otherwise balanced diet.

Aim to keep saturated and

trans

fatty acid daily intake less than

10% of total calories. Many Americans consume two to three times as much saturated fat as recommended.

Total fat, saturated fat, and trans fat content of selected foods is
given in

Table 17

Cholesterol is discussed in more detail in the free supplement to
