Weight loss can lead to iron-deficiency anemia. Excessively restricting certain nutrients during weight loss, such as strictly limiting meat intake, and over-consuming fat during exercise may result in insufficient energy supply. When the body's consumption exceeds intake and fails to meet physiological needs, anemia can develop, and some individuals may develop iron-deficiency anemia. If iron-deficiency anemia occurs, it is advisable to temporarily stop weight-loss efforts and actively treat the condition. Without timely treatment, more serious complications may arise over time.
