i didnt actually know locust caused weight gain,my leo eats a good few,well 3rd hoppers not locusts i know waxies are meant to be bad but i think ideally the main food should be crix,i can understand why ppl dont like them tho they are foul but silent browns are just about bearable,until you find the escapees all over the house,i would say my feeding is crix and hoppers alternate days the every 10th day as may waxies as he wants,hes not fat at all so i cant be doing much wrong
