Is Zink useful for weight loss?

Whether zinc is useful for weight loss is a common question, but the scientific evidence is limited. Zinc is an essential trace mineral involved in many metabolic processes, including insulin sensitivity and thyroid function. Some observational studies have found lower zinc levels in obese individuals, and small intervention trials suggest that zinc supplementation might modestly support weight loss, especially when combined with a calorie-restricted diet. However, the effects are generally small and inconsistent. There are no high-quality randomized controlled trials demonstrating significant weight loss from zinc alone. Moreover, excessive zinc intake can cause side effects like nausea and copper deficiency. Therefore, zinc is not a magic bullet for weight loss. A balanced diet providing adequate zinc (e.g., from meat, nuts, legumes) is beneficial, but supplementation should only be considered after consulting a healthcare professional. The evidence level is unclear.
