Hi... I saw pretty much threads about this, but I never saw anything posted by somebody this young, so here we go. I'm 15.5 years old, 161cm tall and 79kg in weight (well, at least I was the last time I was measuring it). My BMI index is 30.5, and that worries me much. I have asthma, and the overweight adds to my breathing problems. I calculated I should take at least 10 kilograms off, but I don't know the best method for that... I heard that diets aren't so effective and healthy. I work out regularly and do Shotokan, but that doesn't seem to help. I try to eat less sweets and more healthier food. I am in the gym for a few months now and just started training Karate again... Any more advice? Thanks!
