Why is the high protein quality of halibut crucial when aiming for muscle preservation during calorie restriction?
Answer
Muscle tissue is more metabolically active than fat tissue, and protein preserves this tissue during a deficit.
During a calorie deficit, the body risks breaking down metabolically active tissue for energy; this tissue is primarily muscle mass. Halibut is an excellent source of lean protein, which is vital for providing the necessary building blocks to preserve muscle tissue under these restrictive conditions. Because muscle burns more calories at rest than fat does, preserving the existing muscle mass helps maintain a higher overall resting metabolic rate, making long-term weight management more sustainable.
