Try and work out everyday even if its just some push ups or sit ups , I have a busy lifestyle too but I try and make time by getting up early in the morning or doing it at night before I take a shower. For food I would say make sure you cut out all unhealthy foods. Substitute certain meals for healthier choices, for me instead of cooking fried chicken I make baked or grilled chicken, and if I need to cook with oil I use something healthy like coconut oil. Also try substituting sugary drinks with water , it cuts out a bunch of calories and your kidneys will love you for it. If you are wanting to loose weight fast try cutting carbs. ( here's an article about it http://articles.mercola.com/sites/ar...-body-fat.aspx
That is pretty much all I have for tips. Best of luck to you , I'm wanting to loose some weight as well.
