Which of the following is an example of a SMART lifestyle goal?

A SMART lifestyle goal is one that is Specific, Measurable, Achievable, Relevant, and Time-bound. The option stating, "I will eat five servings of fruits and vegetables each day for the next three weeks," meets all these criteria.

It is specific about the quantity of servings (five servings of fruits and vegetables). The goal is measurable, as one can easily track the amount of fruits and vegetables consumed each day. It is achievable, assuming the individual has access to fruits and vegetables, making it a reasonable goal. The relevance is clear, as increasing fruit and vegetable intake is directly related to improving diet and overall health. Lastly, it is time-bound, as it sets a clear timeframe of three weeks within which the goal should be accomplished.

In contrast, the other options lack one or more elements of the SMART criteria. For example, exercising for one hour daily is specific and measurable, but without a timeframe or an achievable context, it may not be seen as fully SMART. The desire to lose weight does not specify how much weight or a time frame, lacking specificity and measurability. Stopping junk food forever is ambitious but fails to set realistic, actionable steps or a defined timeframe, impacting its achievability and relevance. Thus
