In this case, one serving contains 31 grams of carbohydrate; therefore, one serving contains 124 calories of carbohydrates. ACE Essentials of Exercise Science, p. 173

Carbohydrates, which are the body's preferred energy source, contain how many kilocalories per gram? - 4 kcal/g - 2 kcal/g - 7 kcal/g - 9 kcal/g

The Correct Answer is: 4 kcal/g Why? Made up of chains of sugar molecules, carbohydrates contain about 4 kcal/g. Proteins also contain 4 kcal/g, while fat contains 9 kcal/g and alcohol contains 7 kcal/g. ACE Essentials of Exercise Science for Fitness Professionals, p. 160

What percentage of total calories comes from 1 serving of carbohydrates, protein, and fat in this product? - Carbohydrate = 43%, Protein = 8%, Fat = 50% - Carbohydrate = 43%, Protein = 50%, Fat = 8% - Carbohydrate = 50%, Protein = 8%, Fat = 43% - Carbohydrate = 8%, Protein = 50%, Fat = 43%

The Correct Answer is: Carbohydrate = 50%, Protein = 8%, Fat = 43% Why? To calculate the percentage of calories from carbohydrate, protein, and fat in 1 serving of a product, divide the number of calories from each macronutrient by the total number of calories in 1 serving.

Contributing to cell membrane function, making bile acids essential for fat absorption, metabolizing fat-soluble vitamins, and making vitamin D are all functions of which nutrient? - Omega-3 fatty acids - Carbohydrate - Protein - Cholesterol

The Correct Answer is: Cholesterol Why? Cholesterol, a fat-like, waxy, rigid four-ring structure, plays an important role in cell membrane function.

A client must achieve a 1,000-calorie deficit per day in order to lose 1 pound per week. TRUE FALSE

The Correct Answer is: FALSE Why? 3,500 calories = 1 lb. Therefore, a 1,000 calorie per day deficit will lead to a loss of 2 pounds per week. The Dietary Guidelines recommend that those trying to lose weight aim for a 500-calorie deficit per day, achieved through decreased caloric intake and/or increased physical activity. Over the course of a week, the 3,500 calorie deficit should lead to a loss of 1 pound. For optimal long-term success and overall health, gradual weight loss of no more than 1 to 2 pounds per week is best. ACE Essentials of Exercise Science for Fitness Professionals, p. 174
