Final answer:
Restricting carbohydrate intake in the morning and at lunch primarily serves the purpose of aiding weight loss by promoting fat burning and reducing excess carb storage, aligning with this dietary approach's goal. Thus, the correct option is b.
Step-by-step explanation:
Restricting carbohydrate intake in the morning and at lunch in this dietary approach primarily aims to promote weight loss. By limiting carbs earlier in the day and consuming them predominantly post-workout, the body relies more on stored fat for energy, aiding in weight reduction.
The strategy of restricting carbohydrates during certain times of the day helps regulate insulin levels, promoting fat burning and reducing the likelihood of excess carbohydrate storage as fat.
This method aligns with the idea of utilizing carbohydrates strategically when the body's insulin sensitivity is higher, typically after intense physical activity, maximizing muscle glycogen replenishment while minimizing fat storage.
Ultimately, this approach supports weight loss goals by manipulating nutrient timing to optimize energy usage and fat utilization throughout the day.
Therefore, the correct option is b.
