Metformin to support losing weight for non diabetic people?

Would you recommend metformin to support losing weight diets for non diabetic people?

The quick answer is, no. Doing the diet will give you 100 times better results.

Benfortiamine is a much better option, which takes glucose and makes ribose out of it, thus enhances the genetic function. Where as metformin makes glucose into lactic acid which is not good, but for sure not as bad as sugar.
