I've always thought based on appearances and research, water signs seem to have the most trouble with weight. Cancers and pisces are either fat or just bloated looking/round faces and bodies. Scorpios I feel just fluctuate between muscular and stocky/stout. Every water sign who is ripped has a roundish face more so but I don't know. Me being scorpio and pisces rising, I struggle consistently. I gain weight and muscle, but harder to lose.
