When it comes to eating healthy, you can't expect to be perfect all the time. Don't deprive yourself of your favorite foods, and don't beat yourself up if you have an off day. The worst thing you can do is give up when you slip up. Remind yourself that all it takes to get back on track is just that—getting back on track the next time you eat a meal or snack. And most important of all, be kind to yourself. Eating healthy gets easier the more you do it, and the older you get, the more important it becomes. So start eliminating these bad habits and adopt good ones now!
