To summarize: The nutritional requirement for dietary carbohydrate, lipids, and proteins, and trace the fate of glucose, lipids, and amino acids after their absorption. Introduction: Nutrient is an essential requirement of the body to perform normal physiological functioning by providing energy, regulating cell metabolism and by promoting growth and development. Nutrients can be classified into two types: macronutrients such as protein, fat and carbohydrate, which is required by the body in large amount and the other is micronutrients such as minerals and vitamins which are required in trace amounts.

Question

What are the 3 macronutrients and how do each provide energy to the body? Define the fed, post-absorptive, fasting, and starved states. Outline changes in the utilization of glucose, fatty acids, amino acids, and ketone bodies as the body transitions from the fed state to the prolonged starvation state. Describe the impacts of insulin, glucagon, epinephrine, and cortisol on CHO, lipid, and protein metabolism. Describe the major pathways that occur in the liver, muscle, adipose tissue. Describe which hormones exercise tends to increase and potential impacts on pathways we’ve discussed. Describe the cori cycle and the glucose-alanine cycle. Describe differences in primary fuel sources by exercise intensity. Describe classical vs moderate CHO loading in preparation for competition in trained athletes. Simple to the point answers please!
