Fat post college guy trying to lose some weight. Advice please?

Hay people I've just finished my degree but gained about 15kgs. Most of it around my stomach and chest (moobish). Iam a guy so iam quite embaressed about it. I've started jogging and swimming. Anything else I can do to get in shape (fatburn primarily) would appreciate some advice. Iam not lazy. My confidence is pretty shit due to this issue.
