Getting fit over 40 seems almost impossible for some people. In fact, it would seem that the deck is stacked against us.

Back when you were a teenager or young adults, losing weight probably seemed easy. Or, at least it was easier than a few years down the road. There's a lot of science to back up the fact that it is harder to lose weight with age. It's not just your imagination.

First of all, metabolism slows with each passing year. That means you can't burn off, or use up, as many calories as when you were younger. By eating the exact same number of calories and keeping all other factors equal, you will gain weight due to this decrease.

Another big hit is that muscle mass starts to deteriorate with age. Muscle plays a large role in metabolism levels so the two go hand in hand. If you don't do something to maintain or even build muscle, you will get fatter and weaker.

By allowing yourself to become weak, you set yourself up for broken bones and other accidents that could lead to a loss of independence at some point. This is seen all too often with older adults.

The solution is to take action now, whatever your age. Once you get the all clear from your doctor, get busy with an exercise program. Whether you choose home workouts or decide to join a gym, every effort you make will play a big role in having a healthy and full life enjoyed on your own terms.

Although it may seem strange and confusing at first, losing weight over 40 isn't difficult provided you go about it the right way. Do yourself a favor and get your hands on a good health and fitness program designed for adults, rather than bodybuilders or kids. Specialized programs will help you set realistic goals designed for the shape you're in now as well as where you want to be.
