When I was a kid, I often played basketball. So I was thin but healthy. When I was about 15, I stopped playing basketball. I also started to drink a lot of drinks high in sugar and eat much more than before. Between 15 and 17, I put on a lot of weight (重量) — about 50 kg.

I didn’t know how big I was till I saw a photo one day. In the photo, I had a fat neck and my stomach was out there. I didn’t like the way I looked. I knew I needed to lose some weight.

I started to drink only water, and eat less and healthier. I ate mainly vegetables and only one piece of meat every day, and stayed away from sugar.

I also started to exercise. Every day, I ran for 30 minutes first, and then I did some push-ups (俯卧撑) for 10 minutes. I also jumped rope (跳绳) for 15 minutes every day.

I kept exercising all the winter. When March came, many people said to me, “Oh, Dave, you’ve been a different person!”

It was true. I lost 25 kg in three months. I liked taking photos, and I noticed the difference in my looks.

I loved the three months. It felt good to lose weight, and it felt even better to set a goal (目标) and go for it.
