How do carbohydrate needs vary during periods of metabolic adaptation, such as during weight loss or muscle gain phases?

Carbohydrate needs vary during periods of metabolic adaptation, such as weight loss or muscle gain, by reflecting changes in energy expenditure and metabolic processes. During weight loss, carbohydrate needs may decrease to create a caloric deficit, while ensuring sufficient intake for energy and muscle preservation. During muscle gain, increased carbohydrate intake supports muscle growth and recovery by providing additional glycogen and energy. Adjusting carbohydrate intake based on these phases helps optimize results and support metabolic goals.
