1. What is metabolism and how does it relate to weight loss
or weight maintenance? Provide examples of metabolic
processes occurring in the body.
Answer: Metabolism refers to the sum of all chemical
reactions that occur in the body to sustain life. It
determines how efficiently the body converts food into
energy. A higher metabolic rate can aid weight loss as it
burns more calories, while a lower metabolic rate may lead
to weight gain. Examples of metabolic processes include
digestion, absorption, and cellular respiration.
2. Explain the role of basal metabolic rate (BMR) in weight
management. How can BMR be influenced?
Answer: Basal metabolic rate (BMR) represents the
number of calories the body needs to perform basic
functions at rest. Understanding BMR is crucial for weight
management as it provides a baseline for calorie intake.
Factors influencing BMR include age, gender, body
composition, hormone levels, and genetic factors.
Generally, individuals with a higher muscle mass tend to
have a higher BMR, contributing to weight loss or
maintenance.
3. How can physical activity impact metabolism? Discuss
the concept of excess post-exercise oxygen consumption
(EPOC) and its relationship to weight loss.
Answer: Physical activity has a significant impact on
metabolism. It increases energy expenditure, both during
exercise and post-exercise. Excess post-exercise oxygenÂÂ
