Assuming you're going to eat the chocolate cake anyways (because, let's be honest, we're all going to eat the cake) then of course there's a point of walking. Cake without walking < Cake with Walking
Pretty much the only reason I exercise is so I can eat more chocolate...
Unless you only went for a walk so that you could make room for said chocolate cake......
you wouldn't burn enough calories from a 30 minute walk to cover a piece of cake.
No no tis touché
Hey you might just wanna burn up some calories before you eat the cake.
A lot of people reward themselves that way.
but... it tastes yummy :(
