why do my clothes feel tighter in the summer when i eat less and excersize more?

Answer 1

summer time causes more swelling - the heat & humidity, ya know

Answer 2

You are retaining water because of the heat. My rings on my fingers do the same thing in the summer and I am sure they don't have that much muscle mass.

Answer 3

maybe you turned the heat up in your washing machine and they shrank?

that or you are increasing muscle mass

Answer 4

your building muscle!! muscle is larger and heavier than fat
