I want bigger glutes? But they dont want to grow, please some sporters help me?

when I am eating much? My glutes grow easier, but my stomach get bigger, which dont look good (altough I exercise my stomach too). When I eat less, my glutes dont want to grow or grow slower. I really dont know what I can make, it makes me sick. I am 1.58 and 63 kg so Im not skinny
