I've been on two Metformin delayed release and diet it works well if i limit carbs that is the secret most people think if they take a drug like metformin that you can eat whatever you want. "YOU CAN'T" I'm Italian so pasta was a main meal for most of my life until 8 years ago I like bread but if I eat bread and pasta I gain weight period. There's no getting around the diet change you must reduce carbs eat more fat but still must watch caloric intake but once you start to lose weight you can exercise more and lose more weight. Just break the carb cycle sugar and processed grains are not healthy for us don't listen to main stream medical advise telling you to eat more whole grain products don't they process a little slower but won't lower you're blood sugar enough. Good luck on your new journey in healthy eating.
