Calories in n out: See the excellent answers on "weight loss". You basically need to burn more calories than you take in. Increase your exercise, choose healthier, less-caloric foods and drinks. The nice thing is that if u build more muscle you will even burn more calories while you sleep! and don't focus too much on weight. Focus more on pants-size, etc. Muscle weighs more than fat but that's ok--its good wt.

Gynecomastia Surgery: Best to be seen in consultation. Also, best to achieve a long-term stable weight prior to undergoing any chest wall surgery. If gynecomastia is present, surgery usually involves a partial resection of glandular tissue plus/minus liposuction surgery of the chest wall. If/when the time is right, i seek consultation with board-certified plastic surgeons. See lots of examples of their work. Best.
