• Answer:

  Losing weight is all about burning off more calories in activity than you take in through food. There's no other way. I think it's possible to reach a plateau where you don't lose for a little while and then after a while the weight loss starts up again. A doctor or nutritionist could tell you how many calories and how much activity is best for your age and build.
