Making better health decisions first requires a clear understanding of basic healthy principles; this includes the balance among fitness, nutrition, habits, and even attitudes. Individual differences also play an important role, from genetic predispositions to physical potentials and limitations. It's important to first learn about the conditions of a healthy lifestyle, or get guidance from a health specialist like a fitness trainer or nutritionist, or from other expert sources. Then take an honest assessment of your personal health and habits, as well as realistic, safe goals. Taking action, following through, evaluating carefully, and observing safety limits all help make better health decisions.
Optimal health and wellness require a state free of disease or other problems that compound when the body is out of balance. The human body is a self-regulating machine that attempts to counterbalance the artificial influences and demands a person puts on it. An unhealthy body resulting from poor health decisions actually represents a successful reflection of the conditions placed upon it. First understand that a person's physical state is the result of habit and time; then you can begin to address new goals with the same patient inevitability despite little apparent daily change. Over an extended period, these incremental changes create total transformation of not only body, but mind.
Transformation may spin its wheels at first as the body seeks to adjust to its new lifestyle. The excitement of a new wellness activity, coupled with desire to change, motivates people to push themselves sometimes harder than necessary in the beginning. You may begin to feel the weight you are trying to pull in this workaday middle period, and momentum may slow or even stop. This first milestone is to push on at least a few weeks, in order to make the new health and wellness activity into a habit. Once habit sets in, and the activity becomes a normal part of your daily routine, then ritual and clear goal visualization begin to work their magic, and you naturally begin to make better health decisions, because it naturally feels better to do so.
Once you achieve this state, you can maintain motivation with rewards; performance will naturally improve as well. More informed decisions affecting your health and wellness become more rewarding in and of themselves. With careful assessment of progress and techniques, as well as professional evaluation of any physical limitations or diseases that may pose a threat, the body's energy will influence the mind's energy into a positive cycle of self-perpetuating improvement. As long as the techniques are sound, well-researched, well-founded, and based not just arbitrary advice, then you can count on being better informed about health decisions, activities, and habits that support your goal.
Finally, compare and confirm all information to make sure it conforms to widely accepted healthy principles. Talk to people who have achieved what you seek to accomplish. Get the advice of specialists, and do your homework. Keep in mind that change is not only possible, but inevitable. It's up to you to choose which track it will take.
