雅思口语P2 Describe an argument that your friends had(文字版)

Mention about the topic, a time when two of my close friends had disagreement with how to lose weight properly comes to my mind. In fact, last weekend when we sat in the dormitory, this disagreement came to us. You know, I used to be a bit overweight and certainly I was wondering if there were any better methods to do. One of my friends thought that diet was the most important part of keeping body shape. He told us that we should avoid eating too much fat and calories in life. By doing so, all the overweight problems would be gone. Another believed that exercise was the only way to lose weight. The point was that we should keep doing it every single day of our life. Above all, they asked me whose opinion I supported and I had to find a right one. It was hard to get, you know. I realized that something was wrong on this topic. Then I told them I tried both of the methods they have mentioned above. I thought they were absolutely right. For me, I trusted them. So, this is quite dangerous for me. Quite impressive. That is it.
