Dr Oz and my heart

Why is that when ever I watch the Dr. Oz show, which is hardly ever, that it's like the same show over and over and over. The main themes are: healthy heart health, weight loss and all the tricks, and delicious superfoods that boost your metabolism and are delicious and simple to make. 

I actually like Dr. Oz and I think he helps a lot of people to become healthier but it really is the same stuff over and over. Anyone else ever noticed that??
