Someone who is hostile, selfish, and unreliable would score low in two dimensions from the Five Factor Model, which are: agreeableness (for hostility and selfishness), and conscientiousness (for unreliability).
<em>Agreeableness</em> refers to the degree to which someone is willing to acquiesce to another individual – thus making them generally more forgiving and helpful. Low scorers would be more prone to fighting with other people than high scorers, and tends to put themselves first. <em>Conscientiousness</em> refers to the degree to which someone is well-organized and disciplined – the lower the score, the messier and less organized the person.
Answer: Planning meals to limit high-fat foods and limiting portion sizes
Explanation: When you're obese it does not matter if you eat at a table with family or in front of a tv it does not minimize your portions or change the diet. Using food as a reward is saying "if you do this you get chips" doing that would just make you have something to look forward to if you do something good.
