                                According to health experts, when dietary protein is insufficient, the body may pull from its muscle reserves, causing muscles to tighten, ache, and stiffen. This can directly address the question: does lack of protein cause tight muscles? This process, known as muscle catabolism, is a crucial reason behind unexplained muscle discomfort and fatigue, especially after physical activity.
