Activity 1. Direction: Summarize the following excerpt below from UnderstandingCalories. Use any of the summarizing techniques learned from module 1.Write your answer on a separate sheet of paper.Understanding CaloriesA calorie, also known as kilocalorie, is a unit of energy. This unit represents theenergy required to heat a kilogram of water on degree Celsius. While people generallylink the term calorie with food, it is a unit of measurement that can be applied to anysubstance possessing energy. For instance, there are 8200 calories in a liter (aboutone quart) of gasoline.Summarizing Technique Use

The energy quotient of a food is often measured in terms of calories. The calorie is known as the…

Sam’s kcalorie needs for weight maintenance based on his height, weight, gender, and activity level are about 2800 kcalories. It is recommended that Sam consume 30% of his total kcalories from fats. How many grams of fat are recommended for Sam?
The catalytic activity of enzymes depends on the presence of appropriate environmental conditions. Pepsin is a digestive enzyme found in the stomach and facilitates the digestion of large proteins. If pepsin is removed from this acidic environment of the stomach and is instead placed in a more basic environment, it will cease to function. Describe the specific effect that a change in environmental pH will have on pepsin and explain how this change can lead to inhibition of its catalytic activity. Respond in 4 to 6 complete sentences.

SHOW YOUR WORK cereal? 2 grams 1. How many Calories in the cereal come from: a. CHO b. fat a. CHO 2. Using 114 as the total number of Calories in a lounce serving, calculate what percent of Calories in this cereal come from: a. CHO b. fat c. protein 3. Compare the AMDR for each of the macronutrients to the % of each of those macronutrients in the cereal. Is the AMDR higher or lower than the amount supplied by the b. fat c. protein c. protein
Background A man just ate a plant-based hamburger with a bun and nothing else on the sandwich.Coincidentally, he visited his doctor an hour later.Out of concern that the man has been eating normally but losing weight, the doctor conducts some tests. The initial tests and observations showed that the man's caloric consumption (using the patient's food diary) should meet his caloric expenditure so that the man should be able to maintain a relatively constant body mass.The doctor ran another test on the man's feces and found that there was an abnormally low level of proteins in the feces. Surprisingly, the doctor found higher than expected levels of amino acids in the man's feces. No other abnormal results were found. Q1) True or false: Based on the new evidence, digestion of proteins appears to be occurring normally. Q2) How are most of the mass loss of the food we absorb into the internal environment? Group of answer choices Feces Urine Carbon dioxide Water Peptides Fiber…
Endurance athletes sometimes follow the exercise-and-diet plan described here: 7 days before an event, do exhaustive exercises so as to all but deplete glycogen stores. For the next 2 to 3 days, consume few carbohydrates and do moderate- to low- intensity exercises. Finally, 3 to 4 days before the event, consume a diet rich in carbohydrates. Explain the benefits of this regime.

Andree is a 25-year-old powerlifter. He weighs 235 lbs and is 6 ft 1in tall. His average day includes 90 min weight lifting at a MET of 6. He does HIIT workouts 3x/week for 30 minutes at a MET of 8. TDEE with TEA including both workouts: 2900 kcals + (961 kcals) + (427) - (213 kcals) = 4075 kcals Analyze his macronutrient needs. Determine the percentage ranges and g/kg ranges for protein and carbs. Determine the percentage range for fats. Prioritize carbohydrates and protein and determine the kcals of each. Determining remaining fat intake and double-check the percentage is within a healthy range. Final Protein g, kcals,%: Final Carbohydrate g, kcals, %: Final Fat g, kcals, %:
Discuss whether or not a high fat, high protein, low carbohydrate nutrition plan is the best choice for an 800 M track athlete in the following scenario: Kip is an 800 meter track athlete who has read many nutrition books hoping to find the ideal diet for his sport. Based upon his readings, Kip knows that dietary protein is needed to help his muscles recover from training. He is now convinced that a high fat, high protein, low carbohydrate diet may be the best choice. As Kip’s nutrition coach you disagree. Answer the following questions: A. What energy systems does an athlete running the 800m event rely on for energy? B. Bioenergetically, what are the nutrition needs to support energy for Kip’s competition? C. Is Kip on the right track with regard to nutrient intake? D. How would you explain whether or not he should follow this new diet?
