Can Metformin be used for weight loss?

Hello, studies have indeed shown that metformin can induce a weight loss of 1-2kg over a period of 1-2 years in some patients. The mechanism of action of this weight loss is not completely understood and some patients do not lose weight. However, in Canada, metformin is not approved for this indication. It is only indicated to treat diabetes or polycystic ovary syndrome. Therefore, the most effective means are still exercise and a better diet and metformin seems to have a modest effectiveness only for weight loss.
