I'm 4ft10 and weigh about 14/15st somewhere in between. I need to lose at least 4st before the end of July as I'm going on a beach and waterpark holiday with my size 10-12 best friend and our very very fit and attractive guy friends and I don't want to look like a whale or a beach ball next to them.
I have no idea how to do this though so any advice would be amazing.
