A woman begins a diet and exercise regimen and loses 30 lb. Will her total body water increase, decrease, or stay the same? Why?

Video transcript

Hey, everyone. Let's take a look at this question together during diet and exercise. A notable portion of weight loss may be attributed to the shedding of water weight. This occurs as a result of the body metabolizing stored carbohydrates, prompting the liberation of water. What metabolic process is referred to in this scenario is it answer choice. A gluco genesis answer choice. B cellular respiration, answer choice C glycogenolysis or answer choice D the creb cycle. Let's work this problem out together to try to figure out which of the following answer choices is the metabolic process that is referred to in this situation of metabolizing stored carbohydrates to shed water weight. So, in order to solve this question, we have to recall what we have learned about. What type of metabolic process involves the metabolizing of stored carbohydrates which would prompt the liberation of water. And we know that carbohydrates are stored in the body as glycogen. So we are looking for a process that metabolizes glycogen, resulting in that shedding of water weight. And we know that the process that metabolizes glycogen into glucose is glycogenolysis. And since diet and exercise requires energy, these stored carbohydrates are then metabolized from glycogen into glucose to provide that energy. So the energy required for diet and exercise is provided by glycogenolysis. And we also know that in glycogenolysis, each gram of glycogen that is broken down to glucose releases water when it is broken down. So, in glycogenolysis, where glycogen is broken down into glucose, it releases water, which is why during diet and extra exercise, a notable portion of weight loss is attributed to the shedding of water weight. Since diet and exercise requires energy which is provided by glycogenolysis in which glycogen is broken down into glucose, which then releases water. So answer choice. C glycogenolysis is the correct answer and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
