Irish sea moss is low in calories and high in dietary fibre, which can help promote a feeling of fullness and potentially support healthy digestion. Additionally, its iodine content may play a role in supporting proper thyroid function, which can positively influence metabolism.

However, it's essential to understand that weight loss is a complex process that involves various factors, including overall calorie intake, macronutrient balance, physical activity, and individual metabolism. Simply consuming Irish sea moss without addressing these other factors is unlikely to lead to significant weight loss.
