I decided to start working out weights, HIIT, and eating healthy foods keeping 500 calories under my maintenance level. It's been two weeks since I started and I already see results if that's any help to you. You will see more results if you have never done much before in the way of weights and dieting. Just depends on how fit you are... the more fit and healthy you are, the more difficult it will be to see big results in a short amount of time. You will definitely see a difference after 6-8 weeks though, if you are consistent.
