Final answer:
Initial weight loss on a low-carbohydrate diet is partly due to water loss from glycogen stores rather than solely from burning fat. Excess energy is stored as fat, and muscle mass influences metabolic rate.a) True
Step-by-step explanation:
The initial weight loss on a low-carbohydrate diet is often not solely from the burning of stored body fat. At first, this weight loss is partly due to the body using up its glycogen stores in the liver and muscles. Glycogen is stored with water, so when it is used for energy, water is released as well. This leads to a quick drop in weight through water loss. It is only after these stores are depleted that the body starts to burn a significant amount of stored fat. Thus, the initial weight loss is a combination of water, glycogen, and some fat.
Regarding the storage of excess energy, this is typically stored as fat in adipose tissue when intake exceeds expenditure. Excess carbohydrates can be converted to fat through a process known as de novo lipogenesis. Furthermore, the individual's metabolic rate is influenced by muscle mass, since muscles burn more calories than fat tissue, even at rest.Initial weight loss on a low-carbohydrate diet results from the burning of stored body fat. When the body is on a low-carbohydrate diet, it enters a state called ketosis. In ketosis, the body switches from using glucose as its primary source of energy to using stored fat. As a result, the stored body fat is burned, leading to weight loss.
