A. Your wish to lose weight is already a good start. The first steps you can do on your own - try to take a look at your life style and recognize the things that lead you to eat more than necessary (e.g. having available snacks in the kitchen, serving high calorie-refreshments, no regular meal schedule etc.) and exercise less. Changing these things may remove some of the obstacles toward losing weight. Weight reduction is a subject too vast for this answer form, so you may want to read more (e.g. here: www.nlm.nih.gov/medlineplus/ency/article/002457.htm).

In addition, consulting a professional (e.g. physician or a dietitian) may also be helpful.

Good luck!
