The most common reason I hear from individuals for not eating healthy or exercising is that they don't have the time to prepare healthy meals or snacks, don't have time to exercise, and don't have time to get the proper amount of sleep each night. My response to this type of statement is that it's not that individuals do not have the time, but they just don't make the time to change.
Finding the time to change your unhealthy habits requires a desire to be healthy, enough so that you will sit down and prioritize the healthy habits such as being physically active and preparing healthy meals over unhealthy habits such as eating convenience foods and spending your nights in front of a television or computer screen. Once the desire to be healthy is there, you just ned to sit down and write on a piece of paper your day to day schedule. List everything that you do from the minute you wake up to the minute you go to sleep. Fitting in time to be healthy may be as simple as getting up an half hour early to jog around your neighborhood, or sacrificing television time to prepare a healthy lunch and snacks for the next day.
Therefore, don't ever tell yourself that you do not have time to be healthy, but remember that if something is important enough to you, then you will find the time to do it. And if anything should be important to you, it should be your health.
