Is it possible to lose breast weight (decrease their size) and how?

Yes: Healthy diet and exercize can lead to weight loss in male breasts. Sometimes however, male breasts have abnormal glandular tissue that is not responsive to weight loss.

Yes but....: When you lose weight you do not have control over what parts of your body lose over others. A healthy and diet exercise program will cause weight loss throughout your body. If your breasts shrink too much, talk to a plastic surgeon about your options for breast enhancement.
