I too am too fat for my liking but I think everyone who carries extra weight and especially when getting older should consider what joswift mentioned, Berberine, as a supplement. I am taking metformin since a buddy has some but I'm eventually switching to Berberine if/when the supply dries out.
Why not simply lose weight instead? Yes of course, but it's like a doc sees a newly type2 diagnosed patient, he's put on drugs immediately. Of course the doc will mention weight loss but he knows few will do it but some might take the medicine at least. It might sound crazy to some but many don't take their medication or only when "they remember to take it."
Aside from the metformin/berberine I started some other old school stuff that affects insulin action in the body, like chromium picolinate and lipoic acid.
