But, unless you're one of the Hollywood hotties, you may not be able to shed that baby bump so quickly after delivery. In fact, if you're over 25 and certainly over 30, losing the baby weight may seem like a losing battle.

Not only has our body packed on the pounds during pregnancy, but along with age, comes a natural tendency to favor fat and gain weight. Once a certain fat level is reached and maintained for an undetermined but specific amount of time, the body accepts this (level) as normal and works at conserving it.

So, as you start to purge those extra pounds, other physiological systems kick and foster

Re-gain. Hormones and neurotransmitters that control your activity level, your hunger level and how you metabolize food are also affected in ways that encourage fat to make its way back.

But, experts assert that there is hope, it just may take more time and conscious effort. And, they add, that it should be viewed and treated as a lifestyle change, and not a "temporary" diet plan geared at simply shedding some extra pounds.

Among the key factors to dropping the weight and keeping it off is the amount of exercise you do over the long haul. Experts suggest a few times a week if possible, but even that may not be enough. In fact, the ideal amount would amount to about 30 minutes per day, even if it's done at intervals, which is also a great way to help you not only maintain a healthy weight, but stay healthy as well.

Furthermore, studies show that losing weight and keeping it off may mean up to 60 to 90 minutes of moderate exercise daily (for most), and they again suggest breaking it into intervals. You can also incorporate exercise into daily activities such as walking instead of driving, taking the stairs instead of the elevator, etc. And, they caution those who are or may be out of shape to start off slow and take it easy and build up gradually.

Overall they suggest sticking within your (daily) calorie and exercise range and finding a program that's practical and easy for you to commit and stick to. And they suggest making small, achievable goals that will enable you to see results, which will in turn be a motivation for you to continue on your successful path.
