Versele Laga food isn't very good quality, it's quite low in protein too & the ingredients are very good, I'm not sure about the other as I couldn't find a GA or ingredients list.
It may be that the new food is better quality & their nutrition has improved which would explain the weight gain, as far as I can tell they're still possibly not getting as much protein as they should, by a year they don't need too much but if they like them a few mealworms would help top it up & some plain cooked chicken or dried chicken once or twice a week would help too.
Walnuts & oats are both really good foods, they do have some protein & healthy fats but not complete protein, broccoli is great too but try to give a wide variety of veg not just broccoli.
