What is the key to a healthy lifestyle? First of all, it is changing bad habits. In order to improve your health, you need to start step by step and change your routine.

That is to slowly replace your unhealthy snacks with fruits and vegetables and choose walking instead of car rides. Firstly, you need to maintain a healthy diet. That means no more late night snacking and fast food.

Surely, you can treat yourself every once in a while with your favourite junk food but not on a daily basis. Maintaining a healthy diet is not just important to lose weight but also to remain healthy.

In order to keep all your bodily functions normal, you need to have a balanced meal. Another thing to pay attention to is physical activity. If you want to have a healthy spine and joints you need daily physical activity. For that reason, choose to walk instead of driving everywhere.

Besides that, you also need exercise. While 30 minutes of vigorous exercise a day will surely be enough, you need to do personalized exercise. That is strengthening key areas. For example, if you sit for a long time in office, you need to exercise your spine and hips.

Depending on your job and in which position you spend most of the day you will arrange your workouts. The best is probably to start going to the gym and your personal trainer will guide you and give you proper exercises.

Healthy body weight is one more important thing to watch for. Surely, it doesn't mean you are unhealthy if you aren't perfectly fit. However, you need to know your limits and know what is the weight you should maintain to be healthy.

Of course, smoking and alcohol don't even have to be mentioned as you already probably know their effect on your body.

But moderate amounts of alcohol won't harm you, so you can enjoy your glass of wine or the occasional beer.
