Getting "fit" can be tough, but for most people, maintaining your fitness is even harder. It's not just about reaching your goal, but staying there. Living a healthy lifestyle (whatever that personally means to you) requires a long-term change, but it is possible if you adopt some of the nutritional habits of people who've gotten fit.
You already know the basics of physical fitness: eat less of the foods that don't offer your body the nutrients it needs, exercise more regularly (however you enjoy!), and make food choices that arm your body with the proteins, fats, and carbohydrates it's in need of. But, the majority of us only take that approach when we're trying to reach a short-term goal such as fitting into a dress, or losing a few pounds before a big event. As soon as that milestone passes, it's easy to fall back into bad habits. The secret is not doing it, but becoming the kind of person who does it everyday.
How do you become the kind of person who lives a healthy lifestyle? Start by reaching out for help. Make an appointment with a dietitian or nutritionist to learn how permanently incorporate healthy eating habits into your long-term life plan. Meet with a trainer who can teach you how to get fit, as well as ways you can continue to exercise daily once you've met your goal. Talk to a counselor to help you overcome issues that may prevent you from maintaining a healthy lifestyle. And make sure you define why you want to get "fit," and understand that fitness and health look very different for every single person.
In the mean time, here are some habits the experts want you to pick up in order to get fit and stay fit.
