How much importance does genetics play in your size(how fat you are, not build) as you age. It seems to me that the older I get the easier it is for me to keep weight off. I was expecting to end up like my mum - apple-shaped and increasingly big as the years go by. But it seems that I am taking more after my dad's family - tall, large built and quite slim. With no real attempt to do anything about it. And I've got friends who seem to get bigger as they age so that they resemble their mothers/fathers. Even though they don't eat hugely and take reasonable amounts of exercise.
Does it really make a difference? Or is it just down to your lifestyle.
