Hi LendingHeart and welcome to 3FC!
Whether or not you might have excess skin after weight loss is determined by your age, genetics, the elasticity of your skin, sun damage, how long you were overweight etc. They're all factors beyond your control.
Unfortunately, there isn't anything you can DO - like supplements or exercises - that will keep you from having excess skin. It's either going to happen or not and no one, not even a doctor, would be able to tell you now if your skin will be a problem for you later.
Try not to let the issue of skin worry you now! Focus on building healthy eating and exercise habits for a lifetime. When you get to goal, wait six months to a year and then assess how your skin responded to the weight loss. You may be one of the lucky ones.
