I'm 195cm and around 70kg, it seems that nowatter what I eat I'll not gain weight, it's the same thing for my brothers and sisters, they are also skinny even though they are not all eating very healthy. Why is that?
What does this mean for my biking, should I eat more when biking? should I eat earlier? should I drik more? etc. etc.
Can somebody help me a bit with these question or perhaps point me to an article that can explain things for me.
