When most people think about what changes after weight loss surgery, one thing usually comes to mind: food.

Truth is, weight loss surgery is a lot more complicated than that. Yes, food will play a big role in your ability to succeed and reach your goals. But so will your decisions, habits, emotions and commitment.

Here's a look at the ins and outs of weight loss surgery–and how food plays a role in all of them.

If you believe the hype in the magazines, you might think skipping carbs or sucking down some sort of liquid concoction is the way to go. Don't believe it. Eating healthy is all about making decisions that give your body the right nutrients. You need ample protein. You need vitamins and minerals. And you need to decide to eat the right amount of these foods–enough to give your body what it needs, not so much that your body can't handle it.

Old habits die hard, which is why being aware of eating habits prior to surgery is important. Even with a smaller stomach, your body could, in time, learn to digest a lot of calories. This means that if you continue to eat the way you did prior to the surgery, you could put your weight loss at risk. Instead, be aware of your bad eating habits. Write them down. Think about them. And work hard to change them.

After surgery, you might not look or feel like yourself. You won't be able to do some of the things you used to do. And people might treat you differently. You may also find yourself missing food. After all, it played a big role in your life prior to weight loss surgery. It can be a sad, difficult time, emotionally. Luckily, there are therapists out there who specialize in helping people come to terms with their new lives.

Hard Work
Initially, the weight will come off fast. After a while, you'll need to work hard to keep it off. The hard work can include exercise and continued focus. If you commit, your chances of succeeding improve dramatically.
