How are Zink and weight loss related?

Zinc is an essential trace mineral involved in numerous metabolic processes, including insulin sensitivity, thyroid function, and appetite regulation. Some observational studies suggest a link between low zinc status and obesity, but evidence for a direct weight-loss effect of zinc supplementation is weak and inconsistent. Mechanistically, zinc may influence leptin signaling, potentially improving satiety. However, randomized controlled trials showing significant weight loss from zinc are lacking. High doses can be toxic (nausea, copper deficiency). A balanced diet with zinc-rich foods (e.g., oysters, beef, pumpkin seeds) is safer than untargeted supplementation. The evidence is primarily mechanistic and insufficient to recommend zinc for weight loss.
